what did Katherine G. Johnson contribute to science?
147674
She is a physicist, space scientist, and mathematician.  She is an Aeorspace Technologist and has done pioneering work on navigation problems.  She was born in 1918, and as far as I know she is still alive.\n\nI hope this helps.

I never knew about this but heres a quote from a website.  This is pretty cool stuff!  Also, he reported that he was "silenced" by thugs  who beat him up and never spoke of his discoveries again after that, sad world.\nQuote:\n\n"Scientists cannot explain how Leedskalnin built coral castle. It was featured on IN Search of with Leonard Nimoy. He moved coral stones weighing as much as 28 tons with equipment designed to only lift 10 tons, and only lift it, not move it. People spying on him with binoculars signed sworn affidavits that they saw coral stones weighing tons, floating in the air like helium balloons.\n\nMy best guess is: He put a strong negative electric charge on them, (at night to avoid the photo electric effect) and the Earth's magnetic field pushed up on them and they floated.\n\nAccording to him, a strong negative charge is really filling it with south magnetic pole units and the whole stone becomes a south magnetic monopole.\n\nI experimented and made a cement brick weighing 15 pounds, to weigh 13 pounds. Did it twice and never tried it again."\n\nIn response to the answer below..  I wasn't trying to declare this as fact I was quoting someone else.  And My enthusiasm was for the trivia not for a new scientific discovery.  Obviously, if it were true then it would be replicated as all science works.  Go easy on me :)  Interesting to note that the user below has been suspended

How about Madame Curie...would that be helpful? I was going to suggest Charles Darwin, but noticed someone already answered...

Karl von Frisch was awarded the Nobel Prize for physiology and medicine in 1973 to honour his work on animal behavior, especially his theory that honey bees communicate by a dance language. This theory was presented first by von Frisch in the 1940's and within a few years it became quite popular as it suggested symbolic communication in a non-human species.

If by candles you mean light, He did experiments on whether or not magnetic fields could influence light.  He discovered it did, but only with led glass not flint, rock crysal or calcareous spar.  He is quoted as saying "Thus magnetic force and light were proved to have relation to each othere.  This fact will likely prove exceeingly fertile and of great value in the investigation of both conditions of natural force."  The Faraday Effect.

Using Copernic Agent Professional (with a ton of search engines) I found a plethora of information and sites about plantations during the Civil War. Good luck on your project!

She is the person who actually did the experiments showing the double helix structure of DNA. Watson and Crick stole that information from her and passed it on as their own.

Already been done.\n\nBased on current observable evidence, there is increasing perenctages of certainty regarding the timeline and history of the development of life on our planet.\n\nIt doesn't exclude G-d. It just outlines the observable and measurable properties of the phyiscal evidence.

Hi! Here are some facts about notable achievements and awards by UH professors, and one distinction for UH itself:\n\nChemist Ralf Kaiser, an associate professor at the University of Hawaii at Manoa, was awarded $2.4 million from the National Science Foundation (NSF) to study Saturn's moon, Titan. \n\nhttp://www.hawaii.edu/cgi-bin/uhnews?20061031092511\n\nA jumping gene first identified in a moth may one day provide a safe alternative to viruses for gene therapy, according to a study by Stefan Moisyadi, a molecular biologist at the University of Hawaii. \n\nhttp://www.hawaii.edu/cgi-bin/uhnews?20061005151316\n\nAstronomers from research institutions worldwide will team up with UH astronomers to use a revolutionary new survey telescope, the PS1, on Haleakala, Maui. \n\nhttp://www.hawaii.edu/cgi-bin/uhnews?20061003170512\n\nThe University of Hawaii was selected to administer the Islands of Opportunity Alliance, a consortium of 19 universities and colleges, both public and private, throughout the Pacific Island nations committed to increasing the number of professional scientists among people from underrepresented minority groups. \n\nhttp://www.hawaii.edu/cgi-bin/uhnews?20061025154534\n\nHope this helps!

Leonardo da Vinci.  Not a scientist, per se, but he did explore scientific thought and was a remarkable engineer and inventor.  Fascinating guy.
