These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. [5] He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and ...
Victor Babeș (1854–1926), Romania – Babesia, the founder of serum therapy. Leo Baekeland (1863–1944), Belgian –American – Velox photographic paper and Bakelite. Ralph H.

A massive amount of new technologies were developed in the 20th century. Technologies such as electricity, the incandescent light bulb, the automobile and the phonography, first developed at the end of the 19th century, were perfected and universally deployed. The first airplane flight occurred in 1903, and by the end of the century large ...
Albert Einstein. Albert Einstein[a] (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is widely held as one of the most influential scientists. Best known for developing the theory of relativity, Einstein also made important contributions to quantum mechanics. [1][6] His mass–energy equivalence formula E = mc2 ...
However, modern mathematicians generally believe that his axioms were highly incomplete, and that his definitions were not really used in his proofs. 300 BC: Finite geometric progressions are studied by Euclid in Ptolemaic Egypt. [43] 300 BC: Euclid proves the infinitude of primes. [44] 300 BC: Euclid proves the Fundamental Theorem of Arithmetic.
German inventions and discoveries are ideas, objects, processes or techniques invented, innovated or discovered, partially or entirely, by Germans. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two. German-born Albert Einstein, world-famous physicist
