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.
