Mechanical computer

Computers have obviously transformed our world. You wouldn’t be listing to my voice right now if it wasn’t for computers. However, the first computers, a device that could perform arbitrary calculations, actually came well before electronics. It was made of gears, cogs, and levers, and it was able to perform mathematical calculations as well as run simple programs. Learn more about Charles Babbage and his analytical engine, the world’s first mechanical computer.

A quantum computer came up with better answers to a physics problem than a conventional supercomputer.

From afar, it looks like a steampunk chandelier. An intricate collection of tubes and wires that culminate in a small steel cylinder at the bottom. It is, in...

También en el siglo XIX el matemático e inventor británico Charles Babbage elaboró los principios de la computadora digital moderna. Inventó una serie de máquinas, como la máquina diferencial, diseñadas para solucionar problemas matemáticos complejos. Muchos historiadores consideran a Babbage y a su socia, la matemática británica Augusta Ada Byron (1815-1852), hija del poeta inglés Lord Byron, como a los verdaderos inventores de la computadora digital moderna. La tecnología de aquella época…

ENIAC (Electronic Numerical Integrator and Computer) was the first programmable, electronic, general-purpose digital computer, completed in 1945. There were other computers that had combinations of these features, but the ENIAC had all of them in one computer. It was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. ENIAC was designed by John Mauchly and J. Presper Eckert to calculate artillery firing tables for the United States Army's Ballistic…
