To move the cursor, T-Square used a Spacewar! game controller built by Kotok and Saunders in 1962. It is not known if Saunders was involved in repurposing it for T-Square. Kotok, who was about 20 years old, did participate. He was known for doing what needed to be done and for taking an interest in "all things ingenious or intriguing." [3] The ...
The modern binary number system, the basis for binary code, is an invention by Gottfried Leibniz in 1689 and appears in his article Explication de l'Arithmétique Binaire (English: Explanation of the Binary Arithmetic) which uses only the characters 1 and 0, and some remarks on its usefulness. Leibniz's system uses 0 and 1, like the modern ...
Converts the numbers and functions into binary code. X register and Y register They are number stores where numbers are stored temporarily while doing calculations. All numbers go into the X register first; the number in the X register is shown on the display. Flag register: The function for the calculation is stored here until the calculator ...
[114] Around 1942 he told Dorothy Maharam how to prove that every complete σ-finite measure space has a multiplicative lifting; he did not publish this proof and she later came up with a new one. [115] In a number of von Neumann's papers, the methods of argument he employed are considered even more significant than the results.
To convert a hexadecimal number into its binary equivalent, simply substitute the corresponding binary digits: 3A 16 = 0011 1010 2 E7 16 = 1110 0111 2. To convert a binary number into its hexadecimal equivalent, divide it into groups of four bits. If the number of bits isn't a multiple of four, simply insert extra 0 bits at the left (called ...
Stibitz was born in York, Pennsylvania, the son of Mildred Murphy, a math teacher, and George Stibitz, a German Reformed minister and theology professor. Throughout his childhood, Stibitz enjoyed assembling devices and systems, working with material as diverse as a toy Meccano set or the electrical wiring of the family home. [3]
A univariate special case can be found in Welch's t-test. More robust and powerful tests than Hotelling's two-sample test have been proposed in the literature, see for example the interpoint distance based tests which can be applied also when the number of variables is comparable with, or even larger than, the number of subjects.

the line-coded signal can be printed on paper to create a bar code. the line-coded signal can be converted to magnetized spots on a hard drive or tape drive. the line-coded signal can be converted to pits on an optical disc. Some of the more common binary line codes include:
