# Write a loop that computes the sum of all squares between 1 and 100

Brightness and Contrast values apply changes to the input image. The Ishango bone Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick.

Later record keeping aids throughout the Fertile Crescent included calculi clay spheres, cones, etc. The Roman abacus was developed from devices used in Babylonia as early as BC. Since then, many other forms of reckoning boards or tables have been invented. In a medieval European counting housea checkered cloth would be placed on a table, and markers moved around on it according to certain rules, as an aid to calculating sums of money.

The ancient Greek -designed Antikythera mechanismdating between and BC, is the world's oldest analog computer.

## Technical Cryptographic Terms Explained

The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J. It was discovered in in the Antikythera wreck off the Greek island of Antikytherabetween Kythera and Creteand has been dated to c. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.

Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use.

() The Monty Hall Paradox In a game-show, the contestant wins if he guesses correctly which one of three doors hides the (only) prize. The rules of the game state that the contestant makes a tentative guess and is then shown one wrong choice among the two doors which he did not pick. Dynamic programming is both a mathematical optimization method and a computer programming method. The method was developed by Richard Bellman in the s and has found applications in numerous fields, from aerospace engineering to regardbouddhiste.com both contexts it refers to simplifying a complicated problem by breaking it down into . Set the drawing transformation matrix for combined rotating and scaling. This option sets a transformation matrix, for use by subsequent -draw or -transform options.. The matrix entries are entered as comma-separated numeric values .

A combination of the planisphere and dioptrathe astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer   and gear -wheels was invented by Abi Bakr of IsfahanPersia in The sectora calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation.

The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. A slide rule The slide rule was invented around —, shortly after the publication of the concept of the logarithm.

It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions.

Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft.

In the s, Pierre Jaquet-Droza Swiss watchmakerbuilt a mechanical doll automaton that could write holding a quill pen.

By switching the number and order of its internal wheels different letters, and hence different messages, could be produced. In effect, it could be mechanically "programmed" to read instructions.Hyperlinked definitions and discussions of many terms in cryptography, mathematics, statistics, electronics, patents, logic, and argumentation used in cipher construction, analysis and production.

We can see from this graph that when the neuron's output is close to $1$, the curve gets very flat, and so $\sigma'(z)$ gets very small. Equations (55) and (56) then tell us that $\partial C / \partial w$ and $\partial C / \partial b$ get very small.

This is the origin of the learning slowdown.
