HAND-HELD CALCULATOR
February 1, 1972 - United States
February 1, 1972 - United States
The first scientific hand-held calculator was introduced for $395 by Hewlett- Packard, named the HP-35 for having 35 keys. It was the first hand-held calculator able to perform logarithmic and trigonometric functions with one keystroke. The red LED display could give scientific notation up to 10 digits mantissa and 2 digits exponent. The price was reduced several times, eventually to $195. By Feb 1975 (when production of the model was discontinued), 300,000 had been sold. The numbers and functions for calculations were entered in “Reverse Polish Notation”(RPN), which used an “ENTER” key but needed no parentheses or “=” key. It ran on rechargeable batteries and had electronics with several integrated circuits in a 79 ×147×34 mm (3.1" x 5.8" x 1.4") case.

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...."
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...."

about Stolen On New Year's
More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)
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 !
