The First Website Ever Made !!!

Today I found out what the first website ever made was.  Simply put, it was a website made by the World Wide Web’s creator Tim Berners-Lee, who was working for CERN (European Organization for Nuclear Research).

first ever webserver

The first ever website was published on August 6, 1991 and served up a page explaining the World Wide Web project and giving information on how users could setup a web server and how to create their own websites and web pages, as well as how they could search the web for information.  The URL for the first ever web page put up on the first ever website was http://info.cern.ch/hypertext/WWW/TheProject.html

This link is no longer active and, unfortunately, nobody bothered to make a copy of this original page, which tended to be updated daily anyways.  The earliest version of it that was recorded was in 1992 and a copy of that page can be found here.

The first ever web browser, called WorldWideWeb, was also created by Tim Berners-Lee.  This browser had a nice graphical user interface; allowed for multiple fonts and font sizes; allowed for downloading and displaying images, sounds, animations, movies, etc.; and had the ability to let users edit the web pages being viewed in order to promote collaboration of information.  However, this browser only ran on NeXT Step’s OS, which most people didn’t have because of the high cost of these systems (this company was owned by Steve Jobs, so you can imagine the cost bloat ;-)).

In order to provide a browser anyone could use, the next browser he developed was much simpler and, thus, versions of it could be quickly developed to be able to run on just about any computer, pretty much regardless of processing power or operating system.  It was a bare-bones inline browser (command line / text only), which didn’t have most of the features of his original browser, but at least could be used on pretty much any computer out there at the time and allowed people to access the information on the web.

The first web server was also written by Tim Berners-Lee called CERN HTTPd, the latter part standing for “Hypertext Transfer Protocol daemon”.   For those not familiar, a daemon is simply a program that more or less runs in the background on a system doing whatever it is programmed to do; in this case, listening for and responding to requests for web pages that exist on the machine it is running on; thus this daemon would be called a “server”.

The First Computer Programmer !!!

The First Computer Programmer

Ada LovelaceAda Lovelace was born on December 10, 1815 and was the  daughter of Lord Byron. She never knew her father as he had left England for good in her early years and he died when she was 9 years old.  Lovelace was initially taught mathematics, something which was not typical for women of the age, due to the fact that her mother was trying to drive out any insanity that may have come from Lord Byron.  Ada showed an aptitude for math and science and one of her later tutors, the famous mathematician and logician Augustus De Morgan, noted that her exceptional skill in mathematics might someday lead her to become “an original mathematical investigator, perhaps of first-rate eminence.”  How right he was.

Besides her other accomplishments, Lovelace was the world’s first computer programmer all the way back in 1842. How did she do this when computers as we know them wouldn’t be invented until long after her death? Well, it turns out there was one Turing Complete computer designed in the mid-19th century.

You see, there are a lot of different ways to make a computer where the way it works “under the hood”, so to speak, is very similar to modern day computers which are “Turing Complete”. If you aren’t familiar, the class of machines known as “Turing Complete”, more or less, are just machines that can produce the result of any calculation.  Or, more aptly, that the machine can be used to simulate the simplest computer such that it is able to do everything this simplest computer can do.  Since this theoretical simplest computer, a “Turing Machine”, can do anything the most complicated computer can do, then any machine that can do everything it can do can also perform any calculation a modern day computer can do, assuming we are ignoring memory sizes and the like (assuming infinite memory).

There was one such computer designed by Charles Babbage in the 1800s. Babbage set out to build a machine that was capable of doing a variety of mathematical calculations correctly every time, getting rid of the inherent errors that happen when humans do calculations by hand.  Babbage’s earliest “computers” that he designed were not Turing Complete, however.  In addition to this, his computers did not run on electricity, but rather were entirely mechanical.  Some of his designs ran on steam, while others needed to be hand cranked to turn the thousands of gears and parts.

Babbage’s first “Difference Engine”, as he called it, was made up of over 25,000 parts, and would have weighed roughly fifteen tons.  However, it was never completed in terms of constructing the machine he had designed; it was only half built.  He then came up with a second Difference Engine, which was an improvement on the uncompleted first Difference Engine, capable of returning mathematical results up to 31 digits.  He never completed building this one either; though he did complete the designs for these machines that have since been proven to work.   For instance, in 1991, his second model of the Difference Engine was constructed and was demonstrated to work by doing a series of calculations.  In 2000, the printer he designed that hooked up to the Difference Engine was constructed and was also shown to work.

After failing to build the second Difference Engine, primarily due to funding problems, Babbage began designing a much more complex machine, which he called the “Analytical Engine”.  The Analytical Engine, unlike his Difference Engines, could be programmed using punch cards, very similar to how early electrical computers were programmed (note: there is some evidence that Ada Lovelace was the one that suggested this improvement to him).  This would then allow someone to make some program with the punch cards once and be able to use this program over and over again, without having to manually do everything every time they wanted to do some operation.

This machine was also able to automatically use results of previous calculations in future calculations.  So you could simply put in a program, crank the gears and let the machine work, spitting out all the results of your program’s execution.  This and other aspects of the underlying architecture made this machine surprisingly similar in architecture to how modern day computers work.  As such, Charles Babbage is known as the “father of the computer”.

Like his early machines that were way ahead of their time, this one was simply designed, never built.  Had he built it, it would have been the first machine ever to be Turing Complete.  Thus, in terms of capabilities, again assuming infinite memory, his machine would have been able to do any calculation a modern day computer could do.

Ada Lovelace, nicknamed by Babbage “The Enchantress of Numbers”, was impressed by Babbage’s Analytical Engine design and between 1842 and 1843 she translated an article by Italian mathematician Luigi Menabrea covering the engine.  She then supplemented the article with notes of her own on the engine, with the notes being longer than the memoir itself.  In these added notes, she included the world’s first computer program that would use the machine to calculate a sequence of Bernoulli numbers and has since been shown to be a valid algorithm that would have run correctly had the Analytical Engine ever been built.

Besides this, she also was one of the first to see that this computer Babbage designed could likely someday be used to do more than just crunch numbers, such as be used for music and other non-mathematical purposes.

Ada died a mere 9 years or so after writing this program, at the very young age of 36 years old on November 27, 1852, from uterine cancer and bloodletting by her physicians.

‘பாரதி’ பிறந்த கதை !!!…. பாரதியார் பிறந்த நாள் …11th Dec …

பாரதி பிறந்தநாள் டிசம்பர்: 11

சுப்ரமணிய பாரதியின் அப்பா சின்னசாமி, அந்தக் காலத்திலேயே பருத்தி ஆலை வைச்சிருந்தாரு. எதிர்காலத்தில் தொழிற்பேட்டை ஒன்றை உருவாக்கும் கனவோட இருந்தாரு. மகன் வளர்ந்தவுடன் அந்தத் தொழிற்பேட்டையை கவனித்துக் கொள்வான்னு நினைச்சாரு.

சுப்ரமணியனோட அம்மா ஐந்து வயசுலேயே இறந்து போயிட்டாங்க. அதோட சுப்ரமணியனுக்குப் படிப்புல பெரிசா ஆர்வம் இல்ல. பள்ளிக்கூடம் முடிஞ்ச ஒடனே தோப்பு, தோட்டம்னு சுத்திப் பார்க்கக் கிளம்பிடுவாரு. அப்புறம் அடிக்கடி தாத்தாவோட வீட்டுக்கும் போவாரு. அவரோட தாத்தா இலக்கியம், பாட்டெல்லாம் வாசிச்சுக் காட்டுவாரு. சுப்ரமணியனுக்குத் தமிழ் இலக்கணமும், தமிழ்க் காப்பியங்களும் ரொம்பவும் பிடிச்சிருந்துச்சு.

மற்றொரு பக்கம் பாடத்தைப் படிக்காமல், வீட்டுப் பாடம் செய்யாம பள்ளிக்கூடம் போன சுப்ரமணியனுக்குத் தண்டனை வழங்கினாங்க. “எனக்கு என்ன பிடிக்கிதோ, அதை யாரும் சொல்லித் தர மாட்டாங்களா”ன்னு சுப்ரமணியன் ஏங்கினான்.

சீக்கிரத்திலேயே பார்வையற்ற ஒரு படிப்பாளியைக் கண்டுபிடிச்சு, அவர்கிட்ட கம்ப ராமாயணத்தைக் கத்துக்கிட்டான். அதுக்கப்புறம் சொந்தமாகவே சுப்ரமணியன் தமிழ் இலக்கணம் கத்துக்க ஆரம்பிச்சான்.

ஒரு நாள் சுப்ரமணியனோட நண்பன் ஒருவன் எட்டயபுரம் ராஜாவோட அரண்மனைக்கு அழைச்சுட்டுப் போனான். ஏதாவது ஒரு குறளின் முதல் வார்த்தையையோ அல்லது ஒரு வெண்பாவின் ஒரு பகுதியையோ சொன்னால், சுப்ரமணியன் உடனடியா எஞ்சிய அடிகளைச் சொன்னான். சுப்ரமணியன் நகைச்சுவையா பேசுறதையும் கவிதை சொல்றதையும் எட்டயபுரம் ராஜா ரசிச்சார்.

“இவன் ஒரு குழந்தை மேதை. பெரிய கவிஞன் ஆவதற்கான அறிவு, உங்க மகன்ட்ட இருக்கு”ன்னு சுப்ரமணியனோட அப்பாகிட்ட சொன்னார் எட்டயபுரம் ராஜா.

ஏற்கெனவே சுப்ரமணியன் செஞ்ச விஷயங்கள் பிடிக்காம இருந்த அவனோட அப்பா, தன் மகன் இப்படிக் கவிதையே கதின்னு இருந்துறக்கூடாதுன்னு நினைச்சாரு. அதனால திருநெல்வேலில ஒரு ஆங்கிலப் பள்ளிக்கு சுப்ரமணியனை படிக்க அனுப்பினார். அப்படிச் செஞ்சா எல்லாம் மாறிடும்னு அவர் நினைச்சாரு.

அங்கேயும் சுப்ரமணியனோட நகைச்சுவை உணர்வும், கவிதை எழுதுற திறனும் சக மாணவர்கள்கிட்ட பிரபலமாச்சு.

ஒரு நாள் வகுப்பறையில சுப்ரமணியன் கொஞ்சம் கண் அசந்துட்டான். சுப்ரமணியனை எழுப்பி, நடத்துன பாடத்தில இருந்து ஆசிரியர் கேள்வி கேட்டார். சுப்ரமணியனுக்கோ பதில் தெரியல. கோபமடைஞ்ச ஆசிரியர், “மேகம் மழையைப் பொழியறது போல, நீ கவிதை சொல்வேன்னு கேள்விப்பட்டேன். ஆனால், நான் கேட்ட கேள்விக்கு உன்கிட்ட பதிலே இல்லையே”ன்னு கேட்டாரு.

“மெத்தப் படித்த ஆசிரியரே, ஒரு விஷயத்தை நீங்க மறந்துட்டீங்க. மேகங்கள் மகிழ்ச்சியை வெளிப்படுத்தத்தான் மழை பொழிகின்றன. நீங்க கேள்வி கேட்கிறதால இல்ல”ன்னு பட்டென்னு பதில் சொன்னான் சுப்ரமணியன். ஆனா, இறுதிப் பரீட்சைல ஃபெயிலான அவன் ஊருக்குத் திரும்பினான்.

இதனால் வருத்தப்பட்ட அவனுடைய அப்பா, எட்டயபுரம் ராஜாவைப் பார்த்து அரசவை பணியில சுப்ரமணியனைச் சேர்த்துவிட்டார். ராஜாவோட நண்பர்கள் சிலருக்கு சுப்ரமணியனைப் பிடிக்கல. அவர்கள்ல ஒருத்தர், “நீங்க பெரிய புத்திசாலி போலத் தெரியுது. ஆனா, பரீட்சைல தோத்துப் போயிருக்கீங்களே” என்று மறைமுகமாகக் கிண்டல் செய்ய ஆரம்பிச்சாரு.

இதனால ரெண்டு பேருக்கும் இடையே வாக்குவாதம் ஏற்பட்டுச்சு. கல்வியைப் பற்றி ஒரு விவாதம் நடத்தலாம்னு முடிவாச்சு. முதல்ல எதிர்த் தரப்பு ஆள் பேசினார். அடுத்ததாகப் பேச ஆரம்பிச்ச சுப்ரமணியன், எல்லோரும் ஆச்சரியப்படுற மாதிரி அற்புதமாகப் பேசினார். அவருடைய வாதம் எதிராளியையும் வசப்படுத்துச்சு.

அந்த விவாதம் முடிஞ்சதும், ஒரு முதிர்ந்த பண்டிதர் எழுந்து சுப்ரமணியன்கிட்ட போனாரு. “நீ உன் வயசை மீறுன புத்திசாலித்தனத்தோட இருக்கிறாய். அதனால், நீ ஒரு பாரதி (அனைத்தும் அறிந்த பண்டிதர்)”ன்னு பட்டம் சூட்டினார்.

அதுக்கப்புறம் சுப்ரமணியனை, எல்லோரும் பாரதின்னே கூப்பிட ஆரம்பிச்சாங்க. உலகம் போற்றும் கவிஞரா மாறின அவர், சுப்ரமணிய பாரதியாராக ஜொலித்தார்.

Nobel Prize Winning Indians… 1913 to 2014 !!!

Rabindranath Tagore was the only Indian Nobel literature laureate. In 1913, In his acceptance speech, he said, “I beg to convey to the Swedish Academy my grateful appreciation of the breadth of understanding which has brought the distant near, and has made a stranger a brother.”
Sir C.V. Raman won the Nobel Prize for Physics in 1930 for his work in the field of light scattering. This effect is now named after him — the Raman scattering. In his speech, he said he was inspired by the “wonderful blue opalescence of the Mediterranean Sea”, during a voyage to Europe in 1921.
Hargobind Khorana (Far right) shared the Nobel Prize for Medicine in 1968, with Marshall W. Nirenberg and Robert W. Holley by showing the the order of nucleotides in nucleic acids. In his speech, he thanked ” a very large number of devoted colleagues, chemists and biochemists” .
S. Chandrasekhar, along with William A. Fowler won the Nobel Prize in Physics in 1983 for their mathematical theory of black holes. The Chandrasekhar limit is named after him. In his speech, he quoted Tagore’s Gitanjali and said, “May I, on behalf of my wife and myself, express our immense gratitude to the Nobel Foundation for this noble reception in this noble city?”
Again a first and only, Amartya Sen won The Prize in Economics in 1998. In his speech, which he began with a “silly thought”, he said, “economists too can learn from the kind of open minded reasoning employed by Tagore and Chandrasekhar”.
Mother Teresa won the Nobel Peace prize in 1979. In a lecture played on the day of the ceremony, she said, “We must give each other until it hurts. It is not enough for us to say: I love God, but I do not love my neighbour.”
Venkatraman Ramakrishnan won the Nobel Prize in Chemistry in 2009, along with Thomas A. Steitz and Ada E. Yonath, “for studies of the structure and function of the ribosome”. In his speech, he thanked “the dedicated work and intellectual contributions of generations of talented postdocs, students and research assistants”.

” All You Need to Know About Nobel Prizes…”

  • The 1936 Nobel Peace Prize

    The 1936 Nobel Peace Prize

From 1901 till this year, Nobel prizes have been awarded 567 times to 864 Laureates and 25 organisations with the youngest winner being Peace Prize awardee Malala Yousafzai of Pakistan at 17 years.

By winning the Peace Nobel at this tender age along with India’s Kailash Satyarthi, Ms. Yousafzai beat the previous record of Lawrence Bragg, who won the Physics Nobel in 1915 at the age of 25.

Kailash Satyarthi (left) and Malala Yousafzai

The word “Laureate” signifies the laurel wreath awarded to winners of athletic competitions and poetic meets in Ancient Greece. In Greek mythology, god Apollo is represented wearing on his head a laurel wreath, a circular crown made of branches and leaves of the bay laurel.

The statutes of the Nobel Foundation say, “If none of the works under consideration is found to be of the importance indicated in the first paragraph, the prize money shall be reserved until the following year.”

“If, even then, the prize cannot be awarded, the amount shall be added to the Foundation’s restricted funds.”

On 27 November 1895, Alfred Nobel signed his last will and testament, giving the largest share of his fortune to a series of prizes in Physics, Chemistry, Physiology or Medicine, Literature and Peace.

In 1968, Sweden’s central bank Sveriges Riksbank established The Sveriges Riksbank Prize in Economic Sciences in memory of Nobel.

At the Nobel Award ceremonies on December 10, the Laureates receive three things: a Nobel Diploma, a Nobel Medal and a document confirming the Nobel Prize amount.

Each Nobel Diploma is a unique work of art, created by foremost Swedish and Norwegian artists and calligraphers.

The Nobel Medals are handmade with careful precision and in 18 carat green gold plated with 24 carat gold.

The Nobel Prize amount for 2014 is set at Swedish kronor (SEK) 8.0 million per full Nobel Prize.

Interesting facts

The average age of all Nobel Laureates in all prize categories between 1901 and 2014 is 59 years.

Two most common birthdays among the Nobel Laureates are May 21 and February 28.

Since 1901, prizes have not been awarded 50 times, most of them during World War I (1914-1918) and II (1939-1945).

Leonid Hurwicz has the distinction of being the oldest Nobel recipient at the age of 90 for Economics in 2007.

Till now, 47 women have won the Nobel while two Laureates declined the prize.

Jean-Paul Sartre, awarded the 1964 Nobel Prize in Literature, declined it as he had consistently declined all official honours.

Jean-Paul Sartre

Le Duc Tho, awarded the 1973 Nobel Peace Prize jointly with U.S. Secretary of State Henry Kissinger for negotiating the Vietnam peace accord, said he was not in a position to accept the award, citing the situation in Vietnam as his reason.

Four Laureates were forced by authorities to decline the Nobel.

Adolf Hitler forbade three Germans Richard Kuhn, Adolf Butenandt and Gerhard Domagk, from accepting the Nobel Prize.

They, however, received the Nobel Prize Diploma and Medal later but not the prize amount.

Boris Pasternak, the 1958 Nobel Laureate in Literature, initially accepted the Prize but was later coerced by authorities of his native country the Soviet Union to decline the award.

Three Peace Laureates — Germany’s Carl von Ossietzky, Myanmar’s pro-democracy icon Aung San Suu Kyi and Chinese rights activist Liu Xiaobo — were under arrest at the time of the award.

The International Committee of the Red Cross (ICRC) was given the Nobel Peace Prize thrice while its founder Henry Dunant won the first Peace Prize in 1901.

Linus Pauling has the distinction of being the only person to have been awarded two unshared Nobel Prizes — the 1954 Prize in Chemistry and the 1962 Peace Prize.

Why is Nobel Peace Prize given by Norway?

Since 1901, when Nobel Prizes were first given, Peace Prize has been awarded by a committee of five, appointed by the Norwegian Parliament Storting in accordance with Alfred Nobel’s will.

Alfred Nobel never disclosed why he didn’t give the task of awarding the Peace Prize to a Swedish body.

The reasons are speculative.

One argument is that Nobel admired Norwegian patriot and leading author Bjornstjerne Bjornson while another is that the Storting was the first national legislature to vote in support for the international peace movement.

Nobel may also have favoured distribution of the tasks related to the Nobel Prizes within the Swedish-Norwegian union or he may have feared that given the highly political nature of the Peace Prize, it might become a tool in power politics thus reducing its significance as an instrument for peace.

“It is my express wish that in awarding the prizes no consideration be given to the nationality of the candidates, but that the most worthy shall receive the prize, whether he be Scandinavian or not,” Nobel wrote in his will.

During the 20th century, eight Scandinavians have won the Peace Prize — five Swedes, two Norwegians and one Dane.

In the nomination and selection process, the committee has the assistance of a secretary and since the establishment of the Norwegian Nobel Institute in 1904, this person is also the institute’s director.

There have been several criticism and protests against decisions of the Norwegian Nobel Committee since 1901.

The selection process

The Peace Prize award ceremony on December 10 is the culmination of a long selection process.

According to rules, there can be a maximum of three Laureates in a category every year.

The Norwegian Nobel Committee begins the whole process by inviting nominations which can be submitted by February 1 each year.

Who are entitled to nominate candidates for the Nobel Peace Prize?

Present and past members of the Nobel Committee and advisers at the Nobel Institute; members of national assemblies and governments, and members of the Inter-Parliamentary Union; members of the Permanent Court of Arbitration and the International Court of Justice at the Hague and members of the Commission of the Permanent International Peace Bureau.

Besides them, members of the Institut de Droit International and present university professors of law, political science, history and philosophy; and holders of the Nobel Peace Prize can also nominate.

After reviewing their qualifications, a shortlist of the candidates is made.

The announcement of the Laureate’s name is often made on a Friday in mid-October at the Nobel Institute building and the award is presented annually on December 10, the day Alfred Nobel died in 1896.

” The Accidental Discovery of Saccharin….”

sweeteners

Saccharin is noted as being the first artificial sweetener, outside of the toxic Lead(II) acetate, and the first product to offer a cheap alternative to cane sugar.  Interestingly enough, like the Chocolate Chip Cookie, it was also discovered entirely by accident.

The chemical was discovered in 1878/9 in a small lab at Johns Hopkins University. The lab belonged to professor of chemistry and all around chemical boffin, Ira Remsen. Remsen was hired by the H.W. Perot Import Firm in 1877, primarily so that the firm could loan the use of his lab to a young Russian chemist and sugar-nerd, Constantin Fahlberg.

The H.W. Perot company wanted Fahlberg to test the purity of a shipment of sugar they’d had impounded by the US government using Remsen’s lab. Fahlberg agreed and happily conducted the tests. After he’d finished, Fahlberg continued to work in Remsen’s lab on various things, such as developing coal tar derivatives.

On the momentous day in question, after working in the lab, Fahlberg was at home about to tuck into his meal when he noticed that the bread roll he’d just taken a bite out of tasted incredibly sweet. After ruling out the possibility of the bread roll being made that way, Fahlberg came to the conclusion that he must have accidentally spilled a chemical onto his hands. Rather than immediately sticking his finger down his throat and throwing up, then rushing to a hospital, Fahlberg reportedly became positively excited at the thought of his new discovery. (Yes, the first non-toxic artificial sweetener was discovered because a scientist didn’t wash his hands after getting chemicals all over them- not unlike how the effects of LSD were discovered.)

At this point, Fahlberg didn’t know which of the many chemicals he’d been working with that day had caused the sweet taste he’d experienced. With no alternative in mind, he resorted to going back to his lab and tasting every chemical he’d left on his desk, FOR SCIENCE! (Note: Nobel Prize winner Barry J. Marshall once did something equally daring, FOR SCIENCE, when he chose to drink the bacteria he thought caused ulcers to prove that they did.)

In any event, Fahlberg eventually discovered the source of the sweet chemical, a beaker filled with sulfobenzoic acid, phosphorus chloride and ammonia. This deadly sounding cocktail had boiled over earlier in the day, creating benzoic sulfinide, a compound Fahlberg was familiar with, but had never had a reason to try shoving into his mouth before that day.

Fahlberg quickly penned a paper with Remsen describing the compound and the methods of creating it. Published in 1879, the paper listed both Remsen and Fahlberg as the compounds creators. However, just a few short years later, after realising the compound’s massive commercial potential, Fahlberg changed his mind and when he patented saccharin in 1886, he listed himself as the sole creative mind behind it. Fahlberg had also applied for an earlier patent on a method of creating saccharin cheaply and efficiently in 1884.

There is no agreed upon consensus on who exactly came up with what in regards to saccharin; some sources say Remsen wanted to be listed as a co-discovered purely because saccharin was discovered in his lab. This is supported by the fact that it’s noted that by the time Fahlberg came onto the scene, Remsen was the president of John Hopkins University and was, thus, absent from lab most of the time. Others claim Remsen was instrumental in the discovery, supported by the fact that earlier in his life he had published many papers on sulfobenzoic acids.  As for what Remsen had to say of the matter, “Fahlberg is a scoundrel. It nauseates me to hear my name mentioned in the same breath with him.”

Regardless, Fahlberg’s new artificial sweetener, advertised as a “non-fattening” alternative to sugar, was fairly successful right off the bat in the states, though it wouldn’t be until sugar shortages in WWI that it would became a widespread hit.

For those of you who are curious, the body doesn’t metabolise saccharin, meaning it has no caloric or nutritional value, unlike sugar. And for all you health conscious types- no, saccharin isn’t dangerous to humans.

This may come as a surprise considering that starting in the 1970s, and as recent as a a little over a decade ago, the widespread belief was that it caused cancer. This was despite the fact that in 1974 the National Academy of Sciences performed a review of all the studies done on saccharin and determined that there was no sound evidence that saccharin was a carcinogen and that the only studies that claimed to show it was were flawed or otherwise ambiguous in their results.

One particular flawed study from the 1970s was nearly the final nail in the coffin of saccharin when the researchers found that saccharin could lead to bladder cancer in rats.  This spurred the Saccharin Study and Labeling Act of 1977, which managed to thwart efforts to ban saccharin outright, instead simply getting it a severe warning label: “Use of this product may be hazardous to your health. This product contains saccharin which has been determined to cause cancer in laboratory animals.”

The rats in the study did indeed have a high rate of bladder tumors.  However, beyond any potential flaws in methodology, there is the obvious caveat that, while similar in some ways, rodents and humans aren’t exactly the same (shocker); so further studies needed to be done to see if the same thing occurred in humans.

What was happening with the rats is that specific attributes in their urine (high pH, high proteins, and high calcium phosphate) was, combined with the undigested saccharin, causing microcrystals to form in their bladders.  This led to damage of their bladder lining, which over time led to tumors forming as their bladders were continually having to be repaired.

Once the exact cause of the tumors was determined, exhaustive tests were done to see if the same thing was happening with primates. In the end, the results came up completely negative, with no such microcrystals forming.

Thanks to this, in 2000, saccharin was removed from U.S. National Toxicology Program’s list of substances that might cause cancer. The next year, both the state of California and the U.S. Food and Drug Administration removed it from their list of cancer causing substances.  In 2010, the Environmental Protection Agency concurred, stating that “saccharin is no longer considered a potential hazard to human health.”

The 1970s wasn’t the first time this compound came under fire. A much earlier and equally as unfounded panic occurred as a result of the Pure Food and Drug Act of 1906. Harvey Wiley, the director of the bureau of chemistry for the USDA, considered saccharin inferior to sugar and lobbied hard against it, even going so far as telling president Teddy Roosevelt that “Everyone who ate that sweet corn was deceived. He thought he was eating sugar, when in point of fact he was eating a coal tar product totally devoid of food value and extremely injurious to health.”

While he got the “totally devoid of food value” part correct, the latter “injurious to health” part wasn’t actually backed by any vetted evidence at the time (or since).

Roosevelt, who ate saccharin regularly, stated, “Anybody who says saccharin is injurious to health is an idiot.”

Needless to say, Wiley soon lost much of his credibility and his job. !!!

Bonus Fact:

  • Saccharin should technically be referred to as, “anhydroorthosulphaminebenzoic acid.” Fahlberg picked something different for obvious reasons. The name chosen, saccharin, is derived from the word, “saccharine” meaning “of or resembling sugar.”  This ultimately derived from the Latin “saccharon,” meaning “sugar,” which itself ultimately derived from the Sanskrit “sarkara,” meaning “gravel, grit.”

போஜராஜன் சபையில் ஆஸ்தான வித்வானாக இருந்த

காளிதாஸன், ஒரு நாள், சற்று மரியாதைக்குறைவான

சொல்லைக் கேட்டதும், சபையிலிருந்து வெளியேறி

கால் போன போக்கில் நடக்கத் தொடங்கினான்.

போஜனுக்கு, காளிதாஸன் இல்லாமல் பொழுது

போகவில்லை. அவனை எப்படிக் கண்டு பிடிப்பது?

ஒரு செய்யுளின்,முதல் இரண்டு அடிகளை எழுதிப்

பூர்த்தி செய்பவருக்குப் பரிசு கிடைக்கும் என்ற

முரசறைவித்தான்.

ஒரு தாசியின் வீட்டிலிருந்த காளிதாஸன், பரிசு பற்றி

எதுவும் அறிந்திராவிட்டாலும், செய்யுளைப் பூர்த்தி

செய்தான்.போஜனிடம் அந்த வரிகளைக் காட்டினாள் தாசி.

பின்னர்,அவளிடமிருந்து விபரங்கள் பெற்று,மாறுவேஷத்தில்

போஜன் புறப்பட்டுச் சென்றான். ஒரு மரத்தடியில் ஒரு

சந்யாஸியைப் பார்த்தபோது, ‘இவர் காளிதாஸனோ’

என்ற சந்தேகம் வந்தது.

பரஸ்பரம் பேச்சு ஆரம்பமாயிற்று.

துறவி, மாறுவேஷத்திலிருந்த போஜனைப் பார்த்து

“நீங்கள் யார்?” என்று கேட்டார்.

“நான்,போஜனிடம் அடைப்பக்காரனாக இருந்தேன்.

அவர் இறந்ததும், எனக்கு இருக்கப் பிடிக்கவில்லை.

வெளியே வந்து விட்டேன்…”

“ஆ!…. என் போஜன் இறந்துவிட்டானா?”

என்று வருந்தி சரம சுலோகம் பாடியதும்,

வேஷக்காரன் கீழே விழுந்து உயிர் விட்டான்.

அவன்தான் போஜன் என்பது சந்தேகமில்லாமல்

தெரிந்துவிடவே, அம்பாளைக் குறித்து,மனமுருகி

சியாமளா தண்டகம் பாடி, “இதோ,போஜன்

எழுந்துவிட்டான்!” என்ற பொருள்பட

இன்னொரு சுலோகம் பாடினான்.

உண்மையாகவே,போஜன் உயிர் பெற்று எழுந்தான்.

இந்தக் கதையை விளக்கமாகச் சொன்னேன்.

கடைசியில் “இந்த சந்தர்ப்பத்தில் தான் காளிதாஸன்,

சந்யாஸியாகக் கபட நாடகம் ஆடினான்…” என்றேன்.

பெரியவாள்,”ரொம்ப சுவாரஸ்யமா இருந்தது.

நடந்து வந்த களைப்பே தெரியல்லே!” என்றார்.

அம்பத்தூர் வந்துவிட்டது.

Image of the Day…Martian Lakebed …!!!

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA’s Curiosity Mars Rover shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.

The scene combines multiple frames taken with Mastcam’s right-eye camera on Aug. 7, 2014, during the 712th Martian day, or sol, of Curiosity’s work on Mars. It shows an outcrop at the edge of “Hidden Valley,” seen from the valley floor.  This view spans about 5 feet (1.5 meters) across in the foreground.  The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Figure A is a version with a superimposed scale bar of 50 centimeters (about 20 inches).

This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits.  These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of river sediment settled out of the water column and onto the lake floor.

NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA’s Science Mission Directorate, Washington. JPL designed and built the project’s Curiosity rover.  Malin Space Science Systems, San Diego, built and operates the rover’s Mastcam.

Good Bye 2014 !!!…Few ” Good Times ” and Inspirational Stories of 2014 !!!

Ladakh’s first female tourist guide

A top cardiac surgeon who didn’t let his humble roots come in the way of his success

A mother who has gone back to school for the sake of her daughters

Two young men who quit high-paying jobs in the US to fix India’s garbage problem

We look back at some of the most inspirational stories featured on Rediff Get Ahead in 2014.

As the year draws to a close, it seems an apt time to look back at some of the stories that brought a smile to our faces and inspired us to look beyond ourselves.

1. Sheetal Jain

Twenty-year-old Sheetal Jain is the daughter of a bar dancer and grew up in Mumbai’s red light district.

But she isn’t letting that define her identity.

Even as you read this, Sheetal is pursuing a course in drumming at the Levine School of Music in Washington DC.

Jain is part of Kranti, an NGO that earlier helped another young lady Shweta Katti to travel the US for further studies.

From being a victim of sexual abuse at the hands of her stepfather to being locked up for months because she had a boyfriend, Sheetal Jain has come a long way.

This is her story!

2. Thinlas Chorol

When tourism companies in Ladakh refused to employ her services as a travel guide because she was a woman, Thinlas Chorol decided them a suitable answer.

In 2009, when she was all of 27, Chorol started her own company, the Ladakhi Women’s Travel Company and became Ladakh’s first female tourist guide

Thinlas Chorol has been awarded by the Ladies’ Wing of the Indian Merchants’ Chamber and only employs women in her company.

3. Dr Ramakant Panda

The biggest challenge was to keep away from getting astray,” Dr Ramakant Panda says as he recalls his childhood in Damodarpur in Odisha’s Jashpur district.

Panda, who would walk 7 km every day to and from school for six years, has done well for himself.

But being serious about studies in a village in the ’60s where education wasn’t necessarily on top of everyone’s mind was a challenge.

Dr Panda has come a long way from there.

He has performed more than 18,000 heart surgeries including one on the former Prime Minister Manmohan Singh is the vice-chairman and managing director at Mumbai’s Asian Heart Institute, of one of India’s best cardiac care hospitals.

Do read his story!

4. Mani Vajipey and Raj Madangopal

The general filth and squalor in India deeply disturbed Mani Vajipey who was pursuing a doctorate in electrical engineering at the University of Delaware.

Along with Raj Madangopal, a friend with whom he bunked classes, Vajipey returned to his homeland and formed Banyan Nation, an organisation that aims to address the garbage crisis in India through technological innovations, better practices and grassroots activism.

Their inspirational story has been documented here!

5. Malvika Iyer

When she was 13, a freak accident cost Malvika Iyer both her hands and severely damaged her legs.

No one knew if she would ever be able to walk again.

But young Malvika braved the odds and emerged victorious.

She graduated in economics from the prestigious St Stephen’s College in New Delhi, met the then President, Dr APJ Abdul Kalam, went on to become a social worker and a motivational speaker.

Along the way, she also became a part of the Global Shapers Community, an initiative of the World Economic Forum.

6. Pavithra YS

Vindhya E-Infomedia is a business processes outsourcing company based in Bengaluru.

With over 600 employees, Vindhya is probably just a speck in the booming BPO market.

What sets it apart is that everyone on its floor operations and most of its 600-plus employees are differently-abled.

Vindhya is the brainchild of Pavithra YS who started this unique company when she was all of 22!

This is her inspiring story!

7. Shadab Hassan

When he was a child, Shadab Hassan sold balloons and candies so he could go to school.

Hassan went on to complete his master’s course in business administration from the Birla Institute of Technology, Mesra.

But instead of taking up a plush corporate job in an MNC, he decided to start a school in his hometown in Ranchi where so no child would ever have to sell balloons and candies for their school fees.

More on that here!

8. Jayashree Kanam

Seven years after the Mumbai floods of July 26, 2005 took her husband away from her,Jayashree Kanam decided to pick up the pieces of her life and move on.

If you thought your life was difficult, this story of a mother returning to school so she can give her daughters a better future is what you should be reading!

9. Mehvish Mushtaq

Information in Srinagar is difficult to come by.

Mehvish Mushtaq learnt it when she wanted to telephone a cousin’s school some years ago.

The school’s website was down.

She didn’t have a phone book handy and there weren’t any directory services that could help her with it.

After considerable search, that included calling up the cousin’s classmates, she finally got the number.

Then there were occasions when a hospital’s number wasn’t easy to come by.

Each time a situation arose, she would scramble for information.

So when Mehvish Mushtaq was asked to create an app as part of an online course in Android application development, she knew just what she wanted to make.

She created Dial Kashmir that lists out everything there is to know about Jammu & Kashmir — from phone numbers and addresses of essential services and tourist attractions to contact details of local business and prayer timings.

This is the story of Mehvish Mushtaq, the first Kashmiri girl to develop an Android app. Do read!

10. Chitra Vishwanathan

Chitra Vishwanathan is better known to her readers as Chitvish.

On her eponymous app, Chitvish dishes out recipes, kitchen advice and handy tips for amateur cooks.

Chitvish, as you would have gathered from the picture above, isn’t your typical Internet wizkid.

How did this 75-year-old take her passion for cooking to the Internet and break a few hundred stereotypes along the way?

We leave you with this fascinating story of Chitra Vishwanathan, which will teach you that you are never too old to learn anything new.
