For my own doctoral dissertation, I spent months doing multiple correlations on a hand-cranked

calculating machine that could not even derive square roots.

116], in his early history of the

calculating machine, described how an electric upright Burroughs machine worked in an office:

In the fall of 1937, a young instructor at Harvard University presented the senior engineer of the International Business Machines Corporation with an extraordinary request: he wanted IBM to assist him in (and pay for) the construction of an automatic

calculating machine that would fulfill the pressing need "for more powerful calculating methods in the mathematical and physical sciences.

At Bethlehem, Taylor recorded two great achievements: first, the development with a colleague of a new "high speed" tool steel, a material that allowed machine tools to cut metal at three to four times the previous speeds; and second, the systematization of years of metal-cutting experiments into a special slide rule for

calculating machine speed and feed.

The average coefficients of adhesion, U, which must be considered when

calculating machine performance.

In 1642 the French mathematician Blaise Pascal (1623-1662) invented a

calculating machine that could add and subtract.

Hartree visited the Moore School to test ENIAC and subsequently wrote an article describing how it worked in the October 12, 1946 issue of Nature entitled, "ENIAC, An Electronic

Calculating Machine.

Emotionally, the cat is a

At twelve years of age Pascal discovered Euclid's axioms unaided; at sixteen he wrote a treatise on conic sections, and at eighteen he invented a

calculating machine.

day for Now we have a black president who acts like a dessicated (and very white)

calculating machine, who campaigned in poetry but governs in such prolix prose that we run the risk of the rabid Republicans rendering him a one-hit wonder.

Later in the decade, IBM introduced the Selective Sequence Electronic Calculator as the company's first large-scale digital

calculating machine, the successful 604 Electronic Calculating Punch - 5,600 of which were built in a ten year period - and the card-programmed Electronic Calculator, the first IBM product designed for computation centres.

Now a leading boffin agrees we are all living in someone's massive

calculating machine.

For 350 years the slide rule was an indispensible logarithmic

calculating machine.

This month's cover shows an ancient

calculating machine, the abacus, juxtaposed with a modern method of disk storage, the floppy disk.

A historian is taking the first steps towards rebuilding a pioneering wooden

calculating machine which was invented in the 19th century by a self-taught mathematician but rejected by the government of the day.
