Electric energy

600 a.C. First observation of electric energy

Jun 26, 600

If Thales hadn't observed the rubbing an ambar dipstick with a skin or wool, he wouldn't known that it can produce little charges that can bring little objects, and rubbing for a long time, can appear a spark.

Electrolysis

Nov 10, 1800

If William Nicholson did hadn't worked on the batterys in his laboratory, he wouldn't discovered the electrolysis accidentally, and it did hadn't allowed a discovered of chemical elements

Periodic table of chemical elements

Aug 20, 1834

If Dimitri Mendeleiev hadn't created the periodic table of chemical elements, we don't could understood the nature and the differents chemical reactions, and maybe we couldn't have knowledge about nuclear process

X rays

Feb 23, 1895

If Röntgen hadn't analysed the electrons, he wouldn't discovered the X rays on his laboratory.

Hiroshima and Nagasaki

Apr 26, 1945

If the nuclear bomb hadn't been invented, USA wouldn't attacked to Japan, and the people hadn't genetics problems

atomic bomb

May 16, 1945

If we hadn't knowledge about chemical elements like Uranio or Plutonio, Leo Szilard couldn't invent the atomic bomb.

nuclear reactors

Mar 17, 1951

If we hadn't knowledge about nuclear process, the nuclear reactors wouldn't been created and its use never had been popular for energy production

DNA analysis

May 28, 1953

If Rosaline Franklin hadn't used the ray x difraction, she wouldn't gound out the DNA structure.

DNA structure

Aug 26, 1953

If Maurice Wilkins hadn't given to Crick and Watson the Rosaline Franklin work, they hadn't discovered the DNA

Chernobyl disaster

Apr 26, 1986

If nuclear reactors hadn't been invented, the nuclear accident in chernobyl wouldn't had occurred and the people around chernobyl reactor hadn't had genetic problems.

human genome

Nov 23, 2003

If the DNA hadn't been structured, the human genome wouldn't been discovered by Department of Energy`s Office of Science and National Institutes of Health of the USA
