how many discoveries were made from 1889-1953?
539694
A whole lot, in 1889 we still didnt have power everywhere. This year the first long distance power lines were run. Einstein hadn't been born yet. Since 1889 some big discoveries were:\n1898- Marie Curie discovered the concept of radioactivity\n1905- Einstein published a paper on special relativity\n1912- Einstein formulated General relativity\n1913- Bohr discovered that electrons orbit around a nucleus in the atom\n1924- Galaxies discovered outside Milky Way\n1926- Quantum Mechanics first formulated\n1927- Heisenberg uncertainty principle\n1929- Discovered Universe is expanding\n1942-1946- Atomic bomb created\n\nThat is just a short list of the many many discoveries we have had since 1889. I hope that helped

Hey there, I haven't found how to access the ones you're looking for, but I came across this one, that may have many that were there as well. It's worth a look.\n\nhttp://www.rexresearch.com/1index.htm

This site has a timeline of everyday inventions; it covers more than the fifty years you want, but it is fairly short and there seems to be some other useful information on the site.\n\nhttp://www.factmonster.com/ipka/A0768871.html
