## When Was the First Computer Invented?

We all know that the first computers were created by Charles Babbage and Ada Lovelace, but when was the first computer invented? Who else invented the computer? Was it the Whirlwind Machine or the Atanasoff-Berry Computer? The answer to this question depends on the category you choose to place it under. Nevertheless, a computer was invented many years before the modern computer. In fact, the first electronic computer was created by a Russian scientist.

## Ada Lovelace was the inventor of the first computer

Ada Lovelace was born into a wealthy family in the 19th century. Her father was a poet, Lord Byron, who left the family shortly after his daughter’s birth. Ada’s mother was a mathematically gifted woman who continued to study math and other sciences. While her father was away on his travels, Lady Byron tutored her in math and other subjects. Eventually, Ada met Charles Babbage, who became her mentor.

Although she was a woman, Ada Lovelace’s work did not gain much recognition until the 20th century. In fact, her contribution was not recognized until the 1970s, when she was named after the computer language ADA. Even then, Ada Lovelace faced a lot of societal opposition and had three children to raise. However, her work and her success are now regarded as the founders of computer science.

In 1833, Ada Lovelace met Charles Babbage, the inventor of the Difference Engine. Ada Lovelace was inspired by the Difference Engine prototype and soon became Babbage’s lifelong friend. Babbage had in mind an Analytical Engine and needed a young woman to write an algorithm for it. This translated article and her comments on it were later referred to as the first computer program.

## Charles Babbage invented the first computer

While many people credit Charles Babbage with inventing the computer, he did not actually invent the machine. Instead, he was a mathematician, philosopher, engineer, and inventor who was known for creating mechanical calculators. Babbage was not particularly popular during his lifetime, but he was an innovator, and his creations have played an important role in the development of today’s computer.

Although he didn’t actually build a computer himself, he made an excellent blueprint for one. The “second difference engine” he envisioned did not use electricity. Instead, it used mechanical systems and a series of levers and springs. Babbage also modeled the machine with many digits and a sophisticated control scheme. He also experimented with printing different tables on different colors of paper, because black print on white paper was hard on the eyes. In 1881, he printed one page of tables in thirteen different colors on 151 shades of paper.

The Analytical Engine was a simpler model of the modern computer, but it incorporated many of the features that computers contain today. Its main components included an arithmetic logic unit, a punch card memory, and an integrated memory. Although it was never fully implemented, Babbage’s machine was a revolutionary leap in the history of computing. The Analytical Engine eventually paved the way for the development of computer science.

## Atanasoff-Berry Computer was the first electronic computer

In 1939, Atanasoff and Berry created the first electronic computer. They used vacuum tubes, binary numbers, and capacitors to compute the answers to mathematical problems. The memory in the machine was built with a pair of drums and 1600 capacitors. At its peak, the Atanasoff-Berry Computer could perform 30 additions and subtraction operations per second. The computer could store up to 60 numbers.

In the summer of 1940, Atanasoff presented the idea to Iowa State College and was granted a grant of $5,000 to develop the machine. At the same time, he hired a gifted graduate student, Cliff Berry. Both men were completing their physics graduate studies when they met. They were able to complete the prototype by the end of the year. In the early 1940s, Mauchly visited Ames to inspect the machine and decide if it was ready to be used. By spring 1942, the machine was ready for use. The name ABC was adopted later, as it was used in popular culture.

Atanasoff’s interest in electronic computation began slowly. He experimented with both theoretical and mechanical methods to solve complex mathematical problems. He and a colleague used an IBM tabulator to solve a spectral analysis problem. They were interested in the use of vacuum tubes for digital computation. However, Atanasoff’s machine was too early and too limited for general purpose use. The Atanasoff-Berry Computer would not become widely used until the late 1960s.

## Leibniz invented differential calculus

Gottfried Wilhelm Leibniz, a German mathematician, was known for his groundbreaking work in differential calculus. Although he had not met Newton or studied under him, Leibniz studied with several prominent scholars in the field and published the details of his discoveries in the journal Acta eruditorum in 1684. However, Leibniz was not recognized for his work until he wrote a book on differential calculus in 1809.

Newton followed the same philosophy as Leibniz and developed fluxional calculus, a method which avoided the informal use of infinitesimals in calculations. In October 1684, Leibniz published a second article on deep hidden geometry, where he stressed the power of differential calculus to investigate transcendental curves. In a series of subsequent publications, the theory evolved into the calculus of variations.

The development of differential calculus is largely credited to Leibniz, who was a prolific writer and multi-talented polymath. Born in Leipzig, he spent his life in Hanover. A true world traveler, Leibniz studied with some of the finest scholars of his time. He earned his bachelor’s and master’s degrees in philosophy at the University of Leipzig and later his doctorate in law at the University of Altdorf in Nuremberg.

While the attribution of the invention of differential calculus to Newton is disputed, Leibniz’s manuscripts did provide hints about how calculus was to be done. While Newton had already published the most important works in the field, Leibniz’s manuscripts contained many clues that pointed to a method of computation he could have developed. In addition, Leibniz’s manuscript lacked the notation necessary to further his work.

## Turing invented binary arithmetic

Several years after the development of the first computer, Alan Turing published a paper defining computational operations and the concept of artificial intelligence. In his paper, he outlined a test for determining whether a computer could simulate the mental functions of a human being. The test involved a man conversing with a computer pretending to be a woman. This was an early attempt to test whether a computer could mimic human thought, and the test proved that a computer had no cognitive capacity beyond that of a human.

After constructing the first computer, Turing applied his theories to arithmetic, describing the use of the compare function. This function essentially combines a sequence of numbers and a binary arithmetic formula. Unlike ordinary calculators, Turing’s algorithm allows users to compare two sequences of numbers. For example, if S_1 is equal to S_2, then each symbol in S_2 will be equal to a.

The first computer was not a complex machine, but it was a very basic one. The first computers were limited to a single type of symbol and were called “Turing machines” by their creators. However, with the advent of modern computing and the development of newer technologies, this was no longer the case. Instead, computer programs are based on a set of symbols, which Turing had developed in his earlier paper.
