How are diamonds formed?

Diamonds are the only gems that are made up of a single element- carbon. Natural diamonds take millions of years to form.

The diamonds that we get today were formed millions of years ago about 120-200 km below the earth’s surface.

The rocks in the earth’s upper mantle contain carbon. Due to variations in temperature, this carbon gets pushed deeper down where it melts under high temperature and pressure. When the temperature reduces, the carbon again gets solidified into a new rock.

Under perfect temperature and pressure conditions (a rare phenomenon), the carbon atoms in the molten rock get crystallised to form diamonds. If the temperature rises or the pressure drops, then the diamond crystals may melt partially or completely. Thousands of years after diamonds are formed, they are transported to the surface by volcanic eruptions.

Diamonds may also be formed due to the high pressure and temperature at the site of meteorite impacts.

How and Why do flowers develop their scent?

Flowers produce scent to attract pollinators or to keep harmful insects or animals away.

When a plant grows, it produces certain essential oils that decompose to form volatile oils. These oils are usually present in petals but they can also be found in fruits, leaves, barks and seeds. When the oil evaporates, the flower gives off smell. The type of fragrance depends on the chemical composition of the volatile oils.

No two flower species have the same scent although their colour and petal structure may look quite similar.

The purpose of the scent is to lure pollinators. Plant species pollinated by bees and flies have sweet scents, while those pollinated by beetles have musty or fruity odours. Large flowers such as Rafflesia arnoldii and Titan arum smell like decomposing corpses and the smell attracts their pollinators, the flies.

Flowers give off scent only when their prospective pollinators are most active. Thus plants like the jasmine that are pollinated by moths and bats bloom at night and emit a sweet fragrance.

While some plants emit strong scents to keep animals away, the Venus flytrap uses its scent to attract insects which are then ‘eaten’ by the plant!

What is the story of Marvin C. Stone and his straws?

How do you drink your beverages, irrespective of whether they are hot or cold? Do you take swigs directly off the glass or bottle, or do you take your time and sip it slowly, using a straw for good measure? If you draw straws to sip your drinks, or even just for picking lots, you are bound to like this one.

The credit for inventing the first paper straws goes to American Marvin C. Stone. Stone was born in 1842 to Chester Stone, an inventor himself, and Rachel. He started to pursue a degree after high school when the Civil War broke out in 1861.

Serves in Civil War

Stone enlisted into service and fought gallantly, but was wounded and disabled from active duty in the Battle of Lookout Mountain. He enrolled as a music major after the war, but eventually graduated in theology. Following his marriage and years as a newspaper journalist, Stone’s inventive spirit shone through when he took to business.

His business life in the late 1870s began when he invented a machine for making paper cigarette holders. His experience with making these holders and his eye for a solution to an everyday problem, led Stone to the first paper straws.

Not the “rye” way

Stone recognised that even though using natural materials such as rye grass and reeds to make straws were popular, they had serious shortcomings. When consuming beverages using these straws, they not only added an additional flavour or taste, but also some unpleasant odour. To add to this, the grass and reeds were also prone to cracking or growing musty.

By winding strips of paper around a pencil and gluing it together, Stone had his first prototypes ready. What followed was more experimenting to make his straws more conducive for drinking.

Stone used paraffin-coated manila paper to ensure that the straws didn’t become too soggy when drinking. He also settled upon 8.5 inches as the ideal length of a straw with a diameter that was just wide enough to prevent things such as lemon seeds from lodging inside and clogging the tube.

Stone received the patent for his paper straws on January 3, 1888. Within a couple of years, Stone’s factory was producing more straws than cigarette holders. By 1896, he had patents for a machine that made artificial straw from paper. He wasn’t around to see his machines go into production in 1906, however, as he died in 1899. The success of these machines brought an end to the hand-winding process.

A kind boss

Apart from being an inventor and tinkerer, Stone was seen as a benevolent boss. A kind and generous employer, Stone looked after the comfort and moral welfare of his employees, which included female workers. The factory was equipped with a singing room and a dance floor, with a library and a meeting room for debates to boot.

The winding process that Stone pioneered with his straws had implications in other industries as well. When electrical engineers employed spiral-wound tubes for radios as they were mass-produced for the first time in the 1920s, they used a similar process. From electrical motors and apparatus to aerospace, textiles and packaging for medicine and other products, the spiral-wound tubing is now found almost everywhere.

The next time you are sipping your favourite drink, spare a thought for the man who gave us the first paper straws. And in case you are doing it with your friends or family, regale them with the story of Stone.

Who invented the ice cream cone?

 

Licking an ice cream off a cone is something that most children can’t say no to. Or even adults for that matter. One of the most delicious treats enjoyed across age groups, the origin of the cone that bears the ice cream is shrouded in mystery.

Over 2,000 years

Before we dive into the story of the cone, a little bit more about ice creams. Their origins can be traced back to over 2,000 years, but it is impossible to fix a specific date or an inventor. What we do know is that the likes of Alexander the Great (4th Century BCE) and Roman emperor Nero Claudius Caesar (1st Century CE) enjoyed these frozen treats in one form or another.

 When ice was mixed with salt, it was possible to lower and control the temperature of the mix of ingredients. This proved to be a major breakthrough in the creation of ice cream as we eat it today. While the invention of wooden bucket freezers with rotary paddles proved to be the next big thing for ice creams, their business truly became profitable and distributable when mechanical refrigeration made its way in the second half of the 19th Century.

It is believed that Menches conceived the idea of filling a pastry cone with scopps of ice cream on July, 23, 1904. According to the story on the Menches Bros. company website, Charles and Frank Menches invented the waffle cone.

It was early in the 20th Century that the cones made their way, revolutionising the way we consume ice creams. While there are many parallel claims as to who invented the ice cream cone, many accounts, including U.S.’ Library of Congress, credit American Charles E. Menches.

It is believed that Menches conceived the idea of filling a pastry cone with scoops of ice cream on July 23, 1904. According to the story on the Menches Bros. company website, cherles and Frank Menches invented the waffle cone.

St. Louis World’s Fair

Having baked waffles in Parisian waffle irons during 1904 St. Louis World’s Fair, they then thought of wrapping the warm waffle around a fid which is a cone-shaped splicing tool that is used for tent ropes. As the waffle held its shape after cooling, it proved to be an edible container for eating ice cream.

The Menches brothers began productions of these “premium” cones on returning home. They even launched their own business called Premium Ice Cream Cone and Candy Company in Akron, Ohio. Chales continued to work on improvements and even received a patent titled “Baking iron for ice-cream cones” on June &. 1909

Marchiony’s cups

Menches was neither the first, nor the last, to claim priority for inventing the ice cream cone. Italian-American immigrant Italo Marchiony received a patent on December 5, 1903 for a device that could make edible cups with handles. While these weren’t rolled up waffles that remain popular, they did improve business. Street-vending became a lot more efficient with these and for this reason, some consider it as the first cones.

Apart from Menches and Marchiony, Ernest Hamwi, Abe Doumar, Albert and Nick Kabbaz, Arnold Formachou, and David Avayou all lay claim to being the first one to invent the edible cone that is now a staple in the ice cream industry. Their stories range from a moment of inspiration to roll a waffle into a cone when a nearby vendor ran out of serving dishes; coming up with an ice cream sandwich in which ice cream, rather than meat, was filled into pastries rolled into a horn; and seeking inspiration from Western Asia and Europe, where pita bread, metal and paper cones were already being used to hold sweets and ice cream. Interestingly, most of these claimants either made or sold confections at the 1904 St. Louis World’s Fair.

While we might never quite be able to say for certain as to who among these actually invented the cone that we now hold in our hands while having an ice cream, the individuals involved collectively transformed the ice cream industry. As the cone ensures that both the product (ice cream) and the package (cone) are consumed together, it is also a win-win in other ways, as there is no waste left behind.

How was the invention of the zip made possible?

In 1918, the United States Navy began using zip fasteners in the clothing and other gear of its men during World War I. By the 1920s, zips could be found in all kinds of clothing, footwear, bags and suitcases. The zip finally arrived on the world scene when fashion designers began using it for haute couture.

The zip was the creation of American inventor Whitcomb Judson. He liked wearing high boots that were all the vogue in 1893, both among men and women. The boots had long shoelaces which took ages to do up. Judson designed a fastener which he called a ‘clasp locker’. It had a slider to link hooks and rings but was clumsy and frequently jammed. The invention was not a success.

It was only 20 years later, in 1913, when Judson employed Swedish engineer Gideon Sundback that the zip took on its present form-two fabric strips with metal or plastic teeth that locked when the zip was pulled closed and unlocked when it was opened.

Judson did not live to see the success of his invention. He died in 1909.

Did you know Velcro which is used in a number of products today was an accidental invention?

Did you know that the same Velcro that allows you to strap on your floaters in an instant, is also used in the Jarvik-7 artificial heart to attach the chambers? NASA astronauts find Velcro indispensable-it holds down objects which would otherwise float away in zero gravity.  

Swiss engineer Georges de Mestral got the idea for Velcro in 1955, when he hike with his dog. When he returned home, he found innumerable burrs stuck to his coat and socks and to the dog’s fur. Curious, De Mestral examined a burr under a microscope. He discovered that it had tiny hooks on its surface that caught in the loops of the fabric (and animal fur). De Mestral devised a way of reproducing the hook and loop arrangement in woven nylon. He called it Velcro-from the French velours (velvet) and crochet (hook).

Velcro can be reused hundreds of times, sometimes outlasting the product to which it is attached! It is peelable and has enormous shear strength or resistance to sideways forces. A piece less than 1.2 cm square can support a load of 1 tonne! Today Velcro is used in an infinite number of products, comes in various colours and is made not only from nylon but also from steel and plastic.

When was mendelevium discovered?

The discovery of mendelevium was announced at the end of April in 1955. It was described by one of its discoverers as “one of the most dramatic in the sequence of syntheses of transuranium elements”.

The search for new elements is something that scientists have been doing for hundreds of years. Once Russian chemist Dmitri Mendeleev organised the elements known at his time according to a repeating, or periodic (and hence the name periodic table), system in the 1860s, the search became a little easier.

This was because the gaps in Mendeleev’s periodic table pointed to elements that weren’t known yet. The properties of these elements, however, could be predicted based on their place in the table and the neighbours around them, thereby making it easier to discover new elements. Mendeleev’s table has since been expanded, to make space for other new elements.

One of those new elements discovered was element number 101, named mendelevium after. Mendeleev. American Nobel Prize winner Glenn Seaborg, who was one of the discoverers of the element, wrote that the discovery of mendelevium was “one of the most dramatic in the sequence of syntheses of transuranium elements”, in a chapter co-written by him for The New Chemistry. Additionally, he also wrote in that chapter that “It was the first case in which a new element was produced and identified one atom at a time.”

Begins with a bang

Ivy Mike, the first thermonuclear device, was dropped for testing on the Eniwetok Atoll in the Pacific Ocean in 1952, sending a radioactive cloud into the air, from which samples were collected. The lab reports suggested that two new elements-elements 99 (einsteinium) and 100 (fermium) – were discovered from the debris. The discoveries came at a time when there was a race to discover new elements. The leading researchers of the U.S. involved in this race were camped at the Radiation Laboratory at the University of California, Berkeley, under the direction of physicist Ernest Lawrence A team of scientists which included Albert Ghiorso, Stanley Thompson, Bernard Harvey, Gregory Choppin, and Seaborg, came up with a plan to produce element 101 using a billion atoms of einsteinium-253 that were formed in a reactor.

The idea was to spread the atoms of einsteinium onto a thin gold foil. As its half-life was about three weeks, the researchers effectively had a week to perform their experiments after receiving it. Based on Ghiorso’s calculations, they were aware that only about one atom of the new element 101 would be produced for every three hours the gold foil was bombarded with alpha particles.

Race against time

As the experiment would yield only a very small amount of the new element, the scientists set up a second gold foil behind the first to catch the atoms. It was a race against time as well as the half-life of element 101 was expected to be a few hours only.

With the Radiation Laboratory atop a hill and the cyclotron at its base, there really was a mad rush to get the samples to the lab on time. The samples “were collected in a test tube, which I took and then jumped in a car driven by Ghiorso”, is how Choppin put it in his own words.

On the night of the discovery, the target was irradiated in three-hour intervals for a total of nine hours. By 4 AM on February 19, 1955, they had recorded five decay events characteristic of element 101 and eight from element 100, fermium. With conclusive evidence of element 101’s existence, Choppin mentions that “We left Seaborg a note on the successful identification of Z =101 and went home to sleep on our success.”

At the end of April 1955, the discovery of element 101 was announced to the world. The university’s press release stated that “The atoms of the new element may have been the rarest units of matter that have existed on earth for nearly 5 billion years… The 17 atoms of the new element all decayed, of course, and the ‘new’ element is for the present extinct once again.”

Cold War era

As element 101 marked the beginning of the second hundred elements of the periodic table, the scientists wanted to name it after Mendeleev, the man behind the periodic table.

Despite the discovery happening during the Cold War era, Seaborg was able to pull enough strings to convince the U.S. government to accept the proposal to name the element after a Russian scientist. The International Union of Pure & Applied Chemistry approved the name mendelevium and the scientists published their discovery in the June 1955 issue of Physical Review Letters.

While only small quantities of mendelevium have ever been produced, more stable isotopes of the element have since been made. The most stable version known as of now has a half-life of over one-and-a-half months, allowing for better opportunities to further study heavy elements and their properties.

Did you know that most of the products that are part of our lives are inventions that happened by chance?

Behind all of these inventions are incredible stories. Let's take a look at some of these inventions that eventually became an integral part of our lives. Here we trace the story of products from lab to lifestyle!

Plastic

Nothing is as ubiquitous as plastic. In fact, this man-made material has become so ingrained into our lives that we interact with one or the other form of plastic every day. But how did its journey begin? It all started with polyethylene, which is more familiar to us as polythene. It is one of the first plastics that was ever used. It was discovered by chance not once, but twice! The first one was sometime before 1900 when German scientist Hans von Pechmann came across a residue in his test tube. He thought that the waxy resin couldn't have any practical applications and failed to check further. The second time was when scientists Eric Fawcett and Reginald Gibson came across this by accident in 1933. When experimenting with ethylene, one of the vessels leaked. The presence of oxygen led to it acting as an initiator, leading to the formation of a white, waxy residue. Thus polythene came to be. The company the duo worked with saw the immense potential of the product and patented it. However, it took a few years until they were able to produce it with perfection. The first product they created out of polythene was a cream-colored walking stick. It was later used widely during World War II as an insulating material for radar cables. The low cost and highly versatile nature of the material were tapped into and the innovation turned into something that permeated into every walk of our lives. And the rest, as they say, is history.

Sticky notes

These canary yellow notes have been around for the past several years. They are universal products and indispensable in offices. Available in a multitude of shapes and colours, these notes are used by not just office-goers but students as well. So how did these sticky notes come to be? This office organising tool was discovered by chance. Spencer Silver was a scientist at the company 3M. He researched adhesives in the laboratory. Over the process, he discovered an adhesive that would stick lightly to surfaces but it wouldn't bond tightly. Silver was trying to develop new adhesives that were stronger and tougher. But this new adhesive was anything but strong or tough. What Silver had discovered was microspheres that would retain their stickiness but had the characteristic of removability. Meanwhile, there was another scientist going through a dilemma. During his practice at the church choir, Art Fry, another 3M scientist, would use little bits of paper to mark the music notes because they would always fall out of the hymn book. He was in search of a bookmark that would stay but not damage the pages. And once he attended the seminar on Silver's microspheres, he had his "Aha" moment. The two scientists partnered and began developing a product. The new adhesive notes proved to be helpful in communication and they could see its immense potential. The notes were supplied to the staff at the company and were later launched to the masses. Thus was born the sticky notes. With it, the duo had forever changed the way people communicate!

Corn flakes

What's for breakfast? Is it corn flakes? It is quite likely that you would have had cornflakes at some point in your life. The Kellogs corn flakes is a known breakfast brand. Did you know that the cereal was developed accidentally? It was in the 1890s that the com flakes were designed. The story starts at the Battle Creek Sanitarium health spa in Battle Creek, Michigan. It was run by brothers John Harvey Kellogg, a doctor, and Will Keith Kellogg who wanted to provide healthy food to the inmates. One night John Kellogg accidentally left a batch of wheat-berry dough midway. This was normally used to produce a type of granola. Rather than throwing it out the next morning, the dough was sent through the rollers. Instead of normal long sheets of dough, they obtained delicate flakes. These were then baked and they discovered a new type of cereal. Will Keith saw the potential of this new cereal and started his own company although John Harvey, who was a proponent of biologic" living, was not interested in making it a business. The Kellogg Company started producing corn flakes for the wider public. It was the start of a whole new cereal breakfast industry.

Lab-grown meat

What's on your plate? Soon it can be lab-grown meat! The farmed meat is getting replaced by meat from the laboratory as meat products are grown from animal cells for human consumption. Recently the U.S. Food and Drug Administration (FDA) cleared lab-grown meat for human consumption as safe. Here, instead of meat reared from livestock, meat is grown in a sterile environment in a laboratory. The living cells from chicken are first taken and then grown in a laboratory. Thus the required meat product is created. Cultivated meat is dubbed green meat as it does not lead to greenhouse gas emissions and global warming. The absence of the use of antibiotics in animals and a humane way of growing meat are some of the pros of lab-grown meat over traditional livestock production. Seen here is a cooked piece of cultivated chicken breast.

Battery

It powers almost everything. But do you know how it all began? The story behind creating the leakproof battery is quite an interesting one. Back in the day, the battery that was popular was the zinc-carbon battery. But they came with a problem. The zinc would swell and burst. It would cause leakage and short circuits and render the device inoperable. The problem was solved by Herman Anthony, an engineer with the company Ray-O-Vac, which was in the battery business. He used a better grade of manganese in the battery. This reduced the swelling. He then used steel to encase the battery. The battery was the first to solve the problem of leakage. In 1939, it was showcased to the public but the patent was received only in 1940. When World War II happened, batteries were rationed out to civilians. Like most companies at the time, Ray-O-Vac started supplying batteries to the military. The battery sealed in steel was widely used in flashlights, radios, walkie-talkies, mine detectors, and so on. After the war, it was used by the masses to power a plethora of devices.

Strikeable matches

Fire has been humankind's greatest discovery. And so have been the discovery of strikeable matches that we use now. It gave us the ability to light fires quickly and made life easier. But did you know that the strikeable match was invented by chance? The story takes us back to 1826. It was an English chemist John Walker who invented it. He was working on an experimental paste that can be used in guns. He noticed that the stick he was using burst into flames when he scraped it. He observed that it was the coating of chemicals on the stick that led to the wooden stick catching fire. That was how the first friction match was invented. He started selling his "friction lights", which became a huge success. While the first friction matches were made of cardboard, he soon started replacing it with wooden splints. However, he never patented his work and Londoner Samuel Jones copied the idea and launched his own matches as "Lucifers" in 1829.

Stories behind inventions

Who set up the world's first website? When was it? Any idea how large the first commercial microwave oven was? Did you know two inventors, working independently, came up with near-identical integrated circuits at about the same time? Who were they? Read on to find out the answers and the backstories of a few other inventions

Connecting the world

In 1969, the Internet took its first baby steps as Arpanet, a network created by the United States Defense Advanced Research Projects Agency (DARPA). It connected universities and research centres, but its use was restricted to a few million people.

Then in the 1990s, the technology made a quantum jump. Tim Berners-Lee, an English software consultant wrote a program called 'Enquire’, named after 'Enquire Within Upon Everything', a Victorian-age encyclopaedia he had used as a child. He was working for CERN in Switzerland at the time and wanted to organise all his work so that others could access it easily through their computers. He developed a language coding system called HTML or HyperText Markup Language, a location unique to every web page called URL (Universal Resource Locator) and a set of protocols or rules (HTTP or Hyper Text Transfer Protocols) that allowed these pages to be linked together on the Internet. Berners-Lee is credited with setting up the world's first website in 1991.

 

Berners-Lee did not earn any money from his inventions. However, others such as Marc Andreessen, who co-founded Netscape in 1994, became one of the Web's first millionaires.

It began with a bar of chocolate!

The discovery that microwaves could cook food super quickly was purely accidental. In 1945, American physicist Percy Spencer was testing a magnetron tube engineered to produce very short radio waves for radar systems, when the chocolate bar in his pocket melted. Puzzled that he hadn't felt the heat, Spencer placed popcorn kernel near the tube, and in no time, the popcorn began crackling. His company Raytheon developed this idea further and in 1947, the first commercial microwave oven was introduced – all of 1.5 metres high and weighing 340 kg!

Since it was too expensive to mass-produce, Raytheon went back to the drawing board and in the 1950s, came out with a microwave the size of a small refrigerator. A few years later came the first regular-sized oven-far cheaper and smaller than the previous models.

Chip-sized marvel

A microchip, often called a "chip" or an integrated circuit (IC), is what makes modern computers more compact and faster. Rarely larger than 5 cm in size and manufactured from a semi-conducting material, a chip contains intricate electronic circuits.

Two separate inventors, working independently, invented near-identical integrated circuits at about the same time! In the late 1950s, both American engineer Jack Kilby (Texas Instruments) and research engineer Robert Noyce (Fairchild Semiconductor Corporation) were working on the same problem- how to pack in the maximum electrical components in minimal space. It occurred to them that all parts of a circuit, not just the transistor, could be made on a single chip of silicon, making it smaller and much easier to produce.

In 1959, both the engineers applied for patents, and instead of battling it out, decided to cooperate to improve chip technology. In 1961, Fairchild Semiconductor Corporation launched the first commercially available integrated circuit. This IC had barely five components and was the size of a small finger. All computers began using chips, and chips also helped create the first electronic portable calculators. Today an IC, smaller than a coin, can hold millions of transistors!

Keeping pace with the heart

Pacemakers send out electrical signals to the heart to regulate erratic heartbeats. Powered by electricity, early pacemakers were as big as televisions, with a single wire or 'lead' being implanted in the patient's heart. A patient could move only as far as the wire would let them and electricity breakdowns were a major cause of worry!

In 1958, a Swedish surgeon and an engineer came together to invent the first battery-powered external pacemaker. Around the same time, American electrical engineer Wilson Greatbatch was creating a machine to record heartbeats. Quite by accident, he realised that by making some changes, he was getting a steady electric pulse from the small device. After two years of research, Greatbatch unveiled the world's first successful implantable pacemaker that could surgically be inserted under the skin of the patient's chest.

Scientist make accurate measurements with the help of various measuring tools. Let’s look at a few of them today.

pH Meter

A pH meter is an electric device that measures the concentration of hydrogen ions (or pH) in a solution to determine whether it is acidic or alkaline. It was invented in 1934 by the American chemist Arnold O. Beckman to measure the sourness of lemons.

It consists of a glass electrode that is sensitive to pH and another reference electrode. The device reads the potential difference between the two electrodes to arrive at results that are displayed electronically in the form of a pH value. This knowledge is critical in chemical lab work and healthcare.

Stethoscope

A stethoscope is a diagnostic instrument commonly used by doctors to listen to sounds made inside the human body-in the lungs, heart and pulse points. The device has two ear buds that are connected by a flexible cord to a sensitive sound detector at the other end.

French physician Dr René Laennec first used a cylindrical roll of paper to listen to chest sounds instead of using his ear in the early 19th Century. Later he improved upon this to create the first stethoscope for medical use (‘Stethos' meaning 'chest’ in Greek).

Barometer

A barometer is an instrument that measures the pressure exerted by the weight of the air in the atmosphere.

As changes in atmospheric pressure are directly related to changes in weather, a barometer is a useful instrument at all weather stations.

The device can be also used to measure altitude since atmospheric pressure changes with altitude.

Breathalyser

It is an instrument used to estimate blood alcohol content (BAC) in one's breath. The instrument that is presently used by the police to discourage drinking and driving is a prototype developed by Robert Frank Borkenstein in 1954. The person exhales into a tube attached to the device which then reads the level of alcohol in the sample breath.

Who was Mary Anning?

Mary Anning was responsible for unearthing a stunning array of prehistoric fossils in the 19th Century. Her discoveries radically changed the way scientists thought about the history of Earth.

Mary Anning was a fossil collector who made some of the most significant geological discoveries at a time when not much was known about the evolution of Earth and life on it.

Mary was bom in England in 1799 in the sea-side town of Lyme Regis. Mary could hardly attend school as her family was very poor. However, she not only taught herself to read and write but also learned about rocks, soil, anatomy of animals, etc. As a child, she would often go to the seashore with her father to collect shells. Mary learnt fossil hunting and cleaning from her father. After her father’s death, she began exploring the rocky hill-ridges along the shore. She had a good eye for the fossils and braved the merciless rocky terrain to unearth a stunning array of prehistoric fossils. The family made a living by selling the ‘curiosities’ found along the seashore.

Along with her brother, Mary discovered the first complete fossil of ichthyosaurus or fish lizard when she was just 11. Some of her important discoveries include fossils of two giant sea reptiles or plesiosaurs, a flying reptile (pterosaur) and some prehistoric fishes. Mary also discovered that ink from belemnites (squid-like prehistoric creature) can be ground up and used for painting.

Mary Anning soon became famous and was considered an authority on prehistory and geology. Eminent scientists often corresponded with her or came to see her collection of fossils. This is especially noteworthy at a time when women did not enjoy equal status with men. Her discoveries at Lyme Regis, radically changed the way scientists thought about prehistoric life and the history of the earth.

How was the ball pen invented?

It was the Biro brothers who invented the ball-point pen in the late 1930s which changed writing forever

The ball-point pen or ball pen, as we know it today, was invented by Hungarian journalist and painter Laszlo Biro.

Biro hated the way fountain pens blotted and smudged on the paper. Once, when he was visiting a newspaper printing press, he saw them using quick-drying ink and rollers. The first thing he did was use the newspaper ink inside a fountain pen but found that the ink was too thick and slow to make it to the nib of the pen.

So he approached his brother, Gyorgy Biro, who was a chemist. Together, they created a rolling ball mechanism for the tip of the pen. This ball picked up ink from a cartridge as it turned in its socket and then rolled again to deposit it on paper. They also created just the right consistency of ink for this kind of nib. They patented their invention in 1938 and called the pen Biro. In some countries, the pens are still known by this name.

Unfortunately, the advent of World War II forced the Biro brothers to flee Hungary because they were Jews. They shifted to Argentina where they began selling their pen commercially under the brand name ‘Eterpen’. That’s how the ball-point pen was born.

Who invented artificial sweetener saccharin?

Did you know Russian chemist Constantin Fahlberg accidentally invented the first artificial sweetener saccharin while working on coal tar derivatives?

The first artificial sweetener to be invented was saccharin. Russian chemist Constantin Fahlberg is credited with this invention, which was actually pretty accidental. In the late 1870s,

 Fahlberg was working with another chemist, Ira Remsen. Together, they were studying substances derived from coal tar. One evening, Fahlberg returned home and sat down for dinner. As he bit into a roll, he found it sweet. He asked his wife about this, but she claimed that her rolls were perfectly normal. Fahlberg then tasted his fingers. They were sweet. He rushed back to his lab and began checking up all that he had done that day. He found that he had accidentally invented a substance that was as sweet as sugar, but had no fattening effects like sugar. He named this substance ‘saccharin’

Fahlberg shared the news of the invention with Remsen, but he filed a patent claiming that he was the sole inventor of saccharin. Saccharin caught on commercially and Fahlberg grew rich. This upset Remsen who was a part of the discovery.

Who invented adhesive tape?

It was American Richard Gurley Drew who came up with the world’s first transparent cellophane adhesive tape in 1930.

The first instance of an adhesive tape was seen in 1845 when Dr Horace Day, an American surgeon, applied rubber glue to strips of cloth to invent surgical tape. Then Johnson & Johnson invented the Band-Aid in 1920.

However, it was a college dropout who came up with a tape that could be used for non-medical purposes. Richard Gurley Drew was a 22-year-old mechanical engineering student when he joined a small sandpaper company called the Minnesota Mining and Manufacturing Company (later called 3M Company) as a lab technician.

In the 1920s, two-tone paint jobs were very popular with car owners. Once, Drew was at an auto shop, testing his company’s sandpaper samples when he overheard the auto painters complaining about the difficulty in making a clean border between the two colours. The incident gave him the idea of developing a masking tape, which when laid on the car, would prevent paint from seeping through and also come off clean without spoiling the paint finish and leaving no sticky residue.

It took Drew two years of experimentation to produce the world’s first paper-based adhesive masking tape. During the trials, there was too little adhesive on the tape and it kept falling off. The frustrated auto painter snapped and said, “Take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it!” (‘Scotch’ meant ‘stingy’.) That is how the tape came to be branded as Scotch Tape in 1925.

Scotch Tape was a huge success and Drew followed it up with the world’s first transparent cellophane adhesive tape in 1930. In the U.K., it was called Sellotape.

What does a lightning rod do?

The lightning rod was invented by America’s founding father Benjamin Franklin.

It protects buildings from lightning. It was invented by American scientist Benjamin Franklin who first proved that lightning and electricity were related, by conducting his fabled kite and key experiment.

The lightning rod is a pointed metal rod mounted on the roof of a building. It is electrically connected to the ground through a thick wire. When lightning strikes the building, the rod attracts the electric current and conducts it harmlessly to the ground through the wire. Thus, the lightning charge does not pass through the building where it could potentially start a fire or cause electrocution.

THE KITE EXPERIMENT

In the mid-18th Century, Benjamin Franklin flew a kite during a storm to see if a key attached to the string would draw an electrical charge. It did and this led to his invention of the lightning rod which protects tall buildings from lightning strikes.

DID YOU KNOW?

Some monuments in the ancient Sri Lankan capital of Anuradhapura bear some of the earliest examples of metal lightning conductors.

What was invented in 1888 by George Eastman?

On September 4, 1888, American inventor George Eastman received a patent for “new and useful improvements” in cameras. On that same day, Eastman also registered the trademark for the name Kodak, a word now synonymous with photography.

What do you, or anyone for that matter, do when you need to capture a moment? You pick up a smartphone, open the camera app, try to best fit the moment you are capturing inside the frame, and tap on the button on the screen to click a photograph. It is as simple as that. With more and more people carrying smartphones these days and with even the basic models boasting a decent camera, amateur photography has been revolutionised like never before.

The first such massive change that promoted amateur photography on a large scale came about in 1888 with the advent of the first Kodak camera. A simple box camera pre-loaded with a 100-exposure roll of film, it made photography less cumbersome than ever before. The man who made it possible was American inventor George Eastman.

Born in 1854 in upstate New York, Eastman had humble beginnings. His father’s death meant that he had to drop out of high school while still a teenager in order to support his family. Starting out as a messenger boy earning $3 a week, he went on to be hired as a junior clerk earning $15 a week at the Rochester Savings Bank in 1874.

The trip that didn’t happen

It was in that same year that he was drawn towards photography. When he made travel plans, a colleague suggested that Eastman record his trip using a “photographic  outfit”. Even though he eventually didn’t make the trip, Eastman had purchased the “outfit and described it as “a pack-horse load”.

Apart from the fact that the camera was heavy and needed a tripod, Eastman would have also had to carry a tent and loads of equipment to develop the photographs if he had gone on the trip. Soon, Eastman was obsessed with the idea of making photography easier.

A company is born

Still holding on to his job at the bank, Eastman spent countless evenings and nights toiling away towards a solution. Realising that wet plates definitely weren’t the way forward, Eastman invented and patented a dry plate formula. He went into the photographic business on a full-time basis, and the Eastman Dry Plate and Film Company was born.

More innovations followed as he began to look for new exposure methods. In order to replace the glass plates, he first came up with a light-sensitive, gelatin-coated paper that could be rolled onto a holder.

In 1888, Eastman introduced the first Kodak camera, which proved to be the first successful roll-film hand camera that came in a compact box with 100 exposures’ worth of film. As the paper proved problematic, Eastman, along with young research chemist Henry  Reichenbach, experimented further until they hit upon the possibility of flexible rolls of sensitised celluloid. At around the same time, another American Hannibal Goodwin independently arrived at celluloid-based camera films, resulting in lengthy patent wars between the parties that was belatedly settled in Goodwin’s favour.

On September 4, 1888, just months after the public release of the camera, Eastman received a patent for “new and useful improvements” in cameras. That very day. Eastman also registered the trademark for the Kodak name.

“We do the rest”

Bolstered by the introduction of the film rolls, the Kodak cameras became a runaway success. An advertising campaign was introduced with the slogan “You press the button, we do the rest.” This was exactly how things panned out as users sent the entire camera back to the manufacturer for developing, printing, and reloading once the film was entirely used up.

Quick to spot an opportunity, Eastman changed the name of his company from Eastman Dry Plate and Film Company to Eastman Kodak Company in 1892. By the time he died aged Eastman Kodak dominated the industry in the U.S. and across the world. It still remains one of the best recognised names in the field, with the word Kodak becoming synonymous to photography.

Apart from being an inventor and innovator, Eastman was also far ahead of his time in various other ways. As a philanthropist, Eastman gave away much of the fortune that he created while still alive to many beneficiaries, including universities. As a businessman, he was among the first to introduce profit sharing as an incentive to employees. But then, he will forever be remembered as the one who placed the power of photography within the grasp of anyone who could just press a button. That button is now more accessible than ever before.

What is origin of an algorithm?

Did you know that the name algorithm comes from the name of Persian mathematician Muhammad ibn Musa al-Khwarizmi?

An algorithm is a set of rules or instructions used in calculations and problem-solving operations. Algorithms date back to 300 BC when their inscriptions were found on Babylonian clay tablets. Originally, they were marking schemes which the common people used to keep track of their cattle and stocks of grain.

The name algorithm comes from the name of Persian mathematician Muhammad ibn Musa al-Khwarizmi who wrote a book on Hindu-Arabic numerals. The Arabic work was translated into Latin as “Algoritmi de numero Indorum.” and later into English, “Concerning the Hindu art of Reckoning.”

Algorithms became a significant part of mathematics laying the foundation for the algebra of logic, variables in calculations, greatest common divisor, approximation of Pi, prime numbers, etc.

The modern algorithm is a sequence of steps laid down to fulfil a particular task. British mathematician and computer scientist Alan Turing worked out how a machine could follow algorithmic instructions and solve complex mathematical problems. Thus began the computer age. Now algorithms are used in all major applications in information technology including navigation (GPS), shopping and internet searches.

Who is the founder of Bose sound system?

Amar G. Bose, founder of the Bose Corporation. Founder Amar Bose didn’t set out to sell speaker systems and headphones. He began his career as an academic engineer at MIT in the late 1950s, licensing power conversion and amplification technology to the U.S. military and government agencies such as NASA

His company’s products can be found in Olympic stadiums, Broadway theatres, the Sistine Chapel and in the space shuttle where they protect astronauts hearing. Amar Bose, the founder of Bose Corporation, was renowned for his invention of high-end stereo speakers.

Bose was brought up in Philadelphia, USA, the son of an immigrant from Kolkata. He became interested in technology when he began repairing model trains and transistors to supplement his family’s income at the age of 13. Bose joined the Massachusetts Institute of Technology and graduated with a degree in Electrical Engineering in the early 1950s. His interest in acoustics was sparked off when some expensive speakers he bought failed to deliver its advertised sound quality.

Bose’s idea was to utilize the space around the loudspeakers to directly reflect the sound to the listeners’ ears rather than letting it bounce indiscriminately off the walls and ceiling. His Direct/Reflecting speaker system patented in 1968 remained the industry standard for 25 years. Bose speakers proved that rich sound need not come from bulky speakers- elegance and simplicity in design could do the job just as well.

DID YOU KNOW THAT BONDAGE HAD ITS BEGINNINGS IN AMERICAN EARLE DICKSON’S KITCHEN?

When American Earle Dickson married in 1917, he discovered that his new bride Josephine was so clumsy in the kitchen that she cut herself umpteen times a day. Being a solicitous husband, Dickson I would rush to her aid with gauze and sticking tape. Soon, Dickson thought of a better idea. He placed small strips of gauze in the centre of the pieces of sticking tape and then lined the tape with crinoline (a stiff fabric) so that it wouldn’t stick to itself. He re-rolled the tape so that Josephine could unwind and cut off whatever she needed. Dickson worked at Johnson & Johnson, which produced cotton and gauze bandages for hospitals and the military. They were impressed with his idea, but the first versions of the bandage they made did not sell very well because they were too big.

Eventually Band-Aid was popularised by distributing them free to Boy Scouts. The company also began machine-cutting them in different sizes in 1924. By 1939, Band-Aid was sterilised, and in 1958, a completely waterproof version was in the market. Today, the company sells millions of dollars worth of the little sticking plasters every year.

HOW DID WRIGHT BROTHERS INVENTED THE AIRPLANE?

The Wright brothers need no introduction. Best known for achieving the first powered heavier-than-air craft flight, the Wright brothers obtained the patent for a “Flying Machine” on May 22, 1906.

The names of Wilbur Wright and Orville Wright will forever be intertwined with the history of flying machines. For, the Wright brothers were the first to achieve the flight of a powered heavier-than-air craft.

The elder of the two, Wilbur, was born in 1867 and was the third child in the Wright family. Orville was the sixth of seven children that his parents had. The seeds for an idea about flying were sown when Wilbur and Orville were still two young boys.

A toy that inspires

Their mother gave them a toy helicopter to play with. This little piece of wood that had two rubber bands to turn a propeller laid the foundation for a lifetime’s work.

Drawn towards flying, the Wright brothers spent plenty of time observing birds in flight. This allowed them to notice that lift was created when birds soared into the wind and the air flowed over the curved surface of their wings. They use this knowledge to build kites, which they even sold to their friends.

Cycling to aviation

As avid cyclists, Wilbur and Orville owned a bicycle shop as adults. Despite the fact that they had less than 10 years of combined high school education, the experience of building bicycles provided them the understanding of early engine design – be it using chains, sprockets, or ball bearings.

Years of riding a bicycle gave them ideas as to how they could control and balance an aircraft. Add to this the countless hours that they had spent observing flight in nature and they had the necessary knowledge and interest to get started.

By 1899, the Wright brothers ventured into flying. Between 1900 and 1902, they researched every aspect of flight, from roll, pitch, and yaw to the rudder, elevator, and performance of the wing. In order to test the aerodynamic qualities of wing models, they even developed the first wind tunnel. The brothers also worked on their own piloting skills by making over a thousand flights on a series of gliders at Kitty Hawk, North Carolina.

Master a control system

Their years of trial and error allowed them to master their glider in all three axes of flight: pitch, roll, and yaw. While the pitch was operated by a forward elevator, their breakthrough discovery included the simultaneous use of roll control with wing-warping and yaw control with a rear rudder.

Even though they had just started conducting experiments with propellers and begun to build their own engines, they applied for a patent in March 1903 for their control system. They were granted U.S. Patent 821,393 for a “Flying Machine” on May 22, 1906. This patent is significant as it laid down a useful and modern means of controlling a flying machine, regardless of whether it was powered or not.

Not ones to be kept waiting, the Wright brothers had already made the first free, controlled, and sustained flights in a powered, heavier-than-air craft on a chilly day at Kitty Hawk, on December 17, 1903. With just a handful of others witnessing history, Orville stayed 12 seconds in the air and flew 120 feet in the first trial at 10.35 a.m. In the fourth and final trial of the day, Wilbur achieved the longest flight of 59 seconds in the air and reached a height of 852 feet. In a little over 100 years since then, human beings have flown farther and faster than ever before, and continue to progressively get better at it.

What did Peter Henlein invent?

Peter Henlein, a locksmith from Nuremburg, Germany, is considered as the inventor of the modern day watch. He was one of the first craftsmen to make small ornamental Taschenuhren, portable clocks worn as pendants or attached to clothing, which were regarded as the first watches. The Pomander Watch is one of the world’s earliest known portable timepieces and is thought to have been made by Henlein in 1505.

Peter Henlein was born in 1485, and very little is known about his early life. It is most probable that he became apprentice as a repair man and locksmith. His appearance in history books start on September 7, 1504 after he was involved in a brawl in which his friend and fellow locksmith George Glaser was killed. Peter immediately went to the local Franciscan monastery where he found safety. Four years later he returned to the Nuremberg where he became one of the most famous locksmiths, who was especially praised for his ability to create small spring-powered brass clock which were then very rare and expensive. With such popularity, it was not strange that local and distant nobility contacted him on regular basis, demanding ever more beautiful and smaller clock designs. As far historical records are concerned, Peter’s first clock was made in 1510, and by 1541 he was well known for his craft and has been tasked on building not only small clocks but also big tower clock for Lichtenau castle.

Even though his spring designs were not particular accurate (they could lose several hours during one day’s work) or even portable (with around 3 inches in size, they were more suited to be worn as a pendant than in pocket), clocks that were made by Peter Henlein soon became sensation in Europe scientific circles and later on by general European population.

Today, Peter Henlein is regarded as a father of modern clocks even though he was not the first locksmith that made small clock designs or was responsible for the discovery of key clock component –mainspring. He died in 1547 knowing that his invention will live forever.
