    DNA
    September 20, 1952 - U.S.A.

    Alfred Hershey and Martha Chase published a report confirming DNA holds hereditary data. Their experiment used the T2 bacteriophage, which, like other viruses, is just a crystal of DNA and protein. It can reproduce when inside a bacterium such as E. coli. When the new T2 viruses are ready to leave the host E. coli cell (and go infect others), they burst the E. coli cell open, killing it (hence the name "bacteriophage"). Hershey and Chase were seeking an answer to the question, "Is it the viral DNA or viral protein coat (capsid) that is the viral genetic code material which gets injected into the E. coli?" Their results indicated that the viral DNA, not the protein, is its genetic code material.

    FORTRAN
    September 20, 1954

    The first successful test compilation and execution of a computer program using what became FORTRAN was run by Harlan Herrick at IBM. It took until 1957 to develop into a fully-operational, commercial product. As implied by its name (FORMula TRANslator), Fortran was designed as a high-level language for technical and scientific applications which primarily needed calculation, rather than working with characters. John Backus at IBM supervised the development of the programming language that would allow users to express their problems in commonly understood mathematical formulae. By 1958 the language was expanded to Fortran II, which included subroutines, functions and common blocks, and in 1962 IBM introduced the extended Fortran IV.

RANDOM QUOTES

  • Happiness
    by Thomas Jefferson

    "...Our greatest happiness does not depend on the condition of life in which chance has placed us, but is always the result of a good conscience, good health, occupation, and freedom in all just pursuits...."
  • Until a man duplicates a blade of grass
    by Earth Day, Thomas Alva Edison Inventor

    "...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

RANDOM FACTS

    about Facts about Drugs

    Facts about drugs can protect against drug abuse. Legal drugs, such as alcohol and tobacco, kill more people than illegal drugs.

Mixing drugs, especially with alcohol, can be fatal. Salary
    about Steve Jobs

    Steve Jobs' annual salary was $1, just enough to keep company health benefits.

Just a line to say I'm living, That I'm not among the dead
Though I'm getting more forgetful And more mixed up in the head.

Just a line to say I'm living, That I'm not among the dead
Though I'm getting more forgetful And more mixed up in the head.

For sometimes I can't remember When I stand at foot of stair, If I must go up for something, Or if I've just come down from there, And before the frig so often My poor mind is filled with doubt Have I just put food away, or Have I come to take some out.

And they're times when it is dark out, With my night cap on my head, I don't know if I'm retiring, Or just getting out of bed So, if it's my turn to write you There's no need of getting sore I may think that I have written, And don't want to be a bore.

So, remember I do love you, And I wish that you were here;
But now it's nearly mail time So I must say "Good-bye, dear."

***************************

There I stood beside the mail box With a face so very red,
Instead of mailing you a letter, I had opened it instead !
