In 1872, one year after Charles Babbage died, the great physicist William Thomson (Lord Kelvin) invented a machine capable of performing complex calculations and predicting the tides in a given place. It is considered the first analogue computer, sharing honours with the differential analyser built in 1876 by his brother James Thomson.

Early computers would use similar punch cards. 1822: Thanks to funding from the English government, mathematician Charles Babbage invents a steam-driven calculating machine that was able to compute tables of numbers. 1890: Inventor Herman Hollerith designs the punch card system to calculate the 1880 U.S. census.

The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done, giving rise to punch-card based computers that took up

He specialized in several fields, including mathematics and mechanical engineering. His two most notable machines were the Difference Engine and the Analytical Engine. The Difference Engine (started in 1822) could compute values of polynomial functions to aid navigation; the more complex Analytical Engine (proposed in 1837) was the first computer that could be considered "Turing complete".

In fact, the main invention was not the wheel itself, which was likely invented the first time someone saw a rock rolling along, but the combination of a wheel and a fixed axle, which allows the wheel to be connected to a stable platform. Without the fixed axel, the wheel has only very limited utility.

More complex calculating and tabulating machines evolved in the early twentieth century, until the first general purpose electronic computer, the ENIAC (Electronic Numerical Integrator and Computer), was developed in 1941-1945. Soon after the invention of the computer was the discovery by Grace Hopper of the first computer bug, a moth trapped in a relay of the Harvard University Mark II Aiken Relay Calculator on 9 September, 1945.

In 1943, Tommy Flowers invented the first programmable electrical computer, and it was called Colossus, where Flowers invented this machine to help the British army decipher the encrypted messages of the German army. In the period between 1943 and 1944 CE, two professors at the University of Pennsylvania built the Eniac computer, which occupied an area of 800 square feet and contained a vacuum valve (in English: the vacuum tube), and this device is considered the grandfather of computers.

Of course, after Mr. Babble invented the computer, then he needed to invent the code to go along with it. So, this lovable yammerhead also invented ENIAC, Colossus and Big Blue in order to beat Bobby Fischer at chess. Of course the inventor of the computer also had to invent Zuse and Zeus as well because the ancient Greeks and their hieroglyphics were also intimately involved in programming on stone tablets and on the sides of pyramid walls.
