first work with x razs had Nikola Tesla but he wasn'z verz interested, after that i think Rentgen did.
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
In July of 1898, Marie and Pierre Curie discovered polonium. Just five months later, in December of 1898, they went on to discover radium as well.
Radium was first isolated in 1898 by Marie Skłodowska-Curie, her husband Pierre Curie, and Gustave Bémont. Marie Curie was born in Poland in 1867. She later became a French citizen. The radioactive element polonium (that she isolated earlier in 1898) is named for her native Poland.
Marie Curie. Uranium was discovered in 1789 by the German chemist Martin Heinrich Klaproth working in Berlin.
Alexander Fleming who discovered penicillin. He was by accident kept a Staphylococcus bacterial plate open which was contaminated by a fungus. What he later noticed strikingly was an area of inhibition of the grown bacteria due to this fungus contamination! Fleming later concluded a chemical released from the fungus inhibited bacterial growth, by this he discovered penicillin!
skin turned grayish, hurt, and he thought radium could be used in treating cancer. that was later proved after his death.
Her research did not lead to the atomic bomb. The only thing that she discovered that was used in the early atomic bombs was the element polonium (in the neutron source initiators), and it was replaced later with electrically activated tritium fusion neutron sources.Her research did foreshadow some of the radiation burns, etc. experienced by survivors of the atomic bombings though.
Planck in his formula E = hf.This was measured by experimenters long before Planck. Einstein's paper on the photoelectric effect explained the observations, Planck later quantified it. Not sure who did the first experiments that discovered the effect.
What Marie Curie did for health was that she isolates radium,later used to treat cancer.
why were viruses discovered later than other types of microorganisms.
Many branches of science do not lend themselves to experiments. Cosmology or astrophysics are subjects where it is extremely difficult to conduct experiments. Theories are developed though thought experiments which are then used to make testable predictions. It is only at the later stage that experiments enter the picture.
No, the words 'later' and 'discovered' are not nouns.The word 'later' is the comparative form of the adjectiveand adverb 'late' (later, latest).The word 'discovered' is the past participle, past tense of the verb to discover. The past participle of the verb also functions as an adjective.Examples:We can take the later train. (adjective)She arrived later than usual. (adverb)I discovered a great little shoe store. (verb)His newly discovered hobby is absorbing all of his time. (adjective)
