Far from being discouraged by this setback, mathematician, philosopher, engineer and inventor Charles Babbage doubled down. He concentrated all his energies on developing the Analytical Engine , which was much more ambitious since it would be capable of performing even more complex calculations by computing multiplications and divisions. Once again, Babbage never got past the design stage, but it was those designs he began in that made him, perhaps not the father of computing, but definitely a prophet of what was to come.
In , 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 by his brother James Thomson. The latter device was a more advanced and complete version, which managed to solve differential equations by integration, using wheel and disc mechanisms. However, it took several more decades until, well into the 20th century, H.
Between and , they built a differential analyser that was truly practical since it could be used to solve different problems, and as such, following that criterion, it could be considered the first computer. By this point, these analogue machines could already replace human computers in some tasks and were calculating faster and faster, especially when their gears began to be replaced by electronic components. But they still had one serious drawback.
They were designed to perform one type of calculation and if they were to be used for another, their gears or circuits had to be replaced.
That was the case until , when a young English student, Alan Turing, thought of a computer that would solve any problem that could be translated into mathematical terms and then reduced to a chain of logical operations with binary numbers, in which only two decisions could be made: true or false. The idea was to reduce everything numbers, letters, pictures, sounds to strings of ones and zeros and use a recipe a program to solve the problems in very simple steps.
The digital computer was born, but for now it was only an imaginary machine. At the end of the Second World War —during which he helped to decipher the Enigma code of the Nazi coded messages— Turing created one of the first computers similar to modern ones , the Automatic Computing Engine, which in addition to being digital was programmable; in other words, it could be used for many things by simply changing the program. Although Turing established what a computer should look like in theory, he was not the first to put it into practice.
That honour goes to an engineer who was slow to gain recognition, in part because his work was financed by the Nazi regime in the midst of a global war. On 12 May , Konrad Zuse completed the Z3 in Berlin, which was the first fully functional programmable and automatic digital computer. If you see something that doesn't look right, contact us!

Robert Hooke is known as a "Renaissance Man" of 17th century England for his work in the sciences, which covered areas such as astronomy, physics and biology. Scottish engineer John Logie Baird made the first mechanical television, which was able to transmit pictures of objects in motion. He also demonstrated color television in Generally, these fulfilled a single purpose. From until his death in , he designed 3 computers , but never actually constructed any of them, due to lack of funding.
In Babbage started working on a Difference Engine its purpose was to compute polynomial functions. If completed it would have had some 25, parts, weighed 13, kg 15 short tons and been 2. Between — Babbage created drawings for the Difference Engine No. Amazingly, it worked! It took 6 years to build, weighs The Analytical Engine , a later Babbage computer design, would have had a whopping bytes of memory!
Punch cards were used as input, based on the Jacquard Loom punch card system , invented at the turn of the 19th century. He saw mechanical computers as a way to remove error. As we all know, necessity is the mother of invention and never was that more true that during WW2! During this period, electromechanical computer technology speed rocketed.
Early electromechanical computers were a sort of hybrid between modern electrical computers and analog computers. Electric switches drove mechanical relays, although parts still wore out quickly, electrical switches could open and close around 1, times faster than mechanical ones, making electromechanical computers much, much faster. At the time the Japanese also had an automated, torpedo firing computer on their submarines.
However, it was not capable of tracking a target. In , Germany, Zuse began work on the Z1 : a mechanical calculator. It worked on a binary system and was fed paper tape.
It was also pretty slow. However, with a little help from his friend Helmut Freier, an electrical engineer, this formed the basis of the Z2…. The Z2 was an electromechanical computer that was capable of slightly more varied functions. It took 0. It had a monitor, keyboard and a 21 inch, flatscreen! He laid out his vision for the internet-based sharing tool in while working at CERN and by others outside of CERN were invited to join the web. Some may know her name or even recognize her face from old films like Samson and Delilah and White Cargo.
But Lamarr was more than just a pretty face. One of the biggest names in computer science and culture as we know it, Bill Gates started his empire writing software for the Altair computer with childhood-friend Paul Allen.
Today, the company that founded Microsoft Windows and Office Suite is still a household name, and though Gates has stepped down as CEO, his company, foundation and philanthropy live on. But if you believe that computer scientists are done making their mark on the world, think again! The field is still in its infant stages, which means you can join in and start making an impact.
