Silly PuttySilly Putty is introduced as a toy by Peter Hodgson, a marketing consultant, who packaged one-ounce portions of the rubber-like material in plastic eggs. It could be stretched, rolled into a bouncing ball, or used to transfer colored ink from newsprint. The original discovery is made in 1943 by James Wright who combined silicone oil and boric acid in the laboratories of General Electric. He was researching methods of making synthetic rubber, but at the time no significant application existed for the material. However, it was passed around as a curiosity. Hodgson saw a sample and realized its potential simply for entertainment and coined its name for marketing it as a toy. Its popularity made him a millionaire.
DNAWatson and Crick submit their first article on the structure of DNA to the journal Nature. It will be published in the April 25, 1953 issue of the magazine.
We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid. This structure has two helical chains each coiled around the same axis… Both chains follow right-handed helices… The novel feature of the structure is the manner in which the two chains are held together by purine and pyrimidine bases… They are joined together in pairs, a single base from one chain being hydrogen-bonded to a single base from the other chain, so that the two lie side by side with identical z-co-ordinates. One of the pair must be a purine and the other a pyrimidine in order for bonding to occur.

In the nation’s first computer sting operation operated by a local law enforcement agency, seven teenagers are arrested on various hacking charges in Fremont, California.

In the lawsuit of Apple Computer versus Microsoft and Hewlett-Packard, Federal District Court Judge Vaughn Walker denies Hewlett-Packard’s request to declare Apple’s copyrights invalid, and also rejects Microsoft’s argument that portions of Windows are covered by the 1985 license from Apple. However, the judge agrees to Microsoft’s request to consider the copyright issue feature-by-feature, rather than on the basis of overall look and feel.

Rumors arise regarding the Michaelangelo computer virus, which is coded to launch its destructive payload on this, Michelangelo’s 516th birthday.
The Michelangelo computer virus reveals itself in as many as one million IBM compatible computers. The virus strikes the first time the computer is turned on after midnight of the previous day, on this, Michelangelo’s 517th birthday. The virus is transmitted through the boot segments of floppy disks that are exchanged between users. Once activated, the program attempts to destroy the data on the hard drive and any disks in use, which often requires the entire hard drive to be reformatted as a result. Concerns over the Michelangelo virus, which had been discovered a month earlier, raises concerns among everyone from personal computer users to world governments. As many as five million computers were reportedly in danger of contracting the virus.
The Michelangelo Virus first discovered in February of 1992, the first to gain mainstream media recognition, sparks near-hysteria in the weeks leading up to March 6, the date the virus is set to deploy. It’s the first time the average person believes his or her life will be thrown into chaos due to a computer failure. As will later be the case with the Y2K bug, Michelangelo’s birthday passes with little damage.
A crew of seven people from five countries begin study in self-contained living, in Biosphere 2, a glass enclosed ecosystem. Their aim was to live within the structure, supported by the several simulated types of ecosystems therein, to provide information which may be applied to solving ecological problems created by man. Biosphere 2 was built in the desert outside of Oracle, Arizona. Visit the official Biosphere 2 website.
