Why did Marie Curie discover radioactivity?
Curie believed scientific research was a public good and championed its utility. She and her husband had discovered that radium destroyed diseased cells faster than healthy cells, and thus that radiation could be used to treat tumours.
What did Marie Curie discover?
When did Marie Curie discover radioactivity?

- What They Had Discovered:
How did Marie Curie measure radioactivity?
The chronometer allowed Marie Curie to measure the length of time during which the charge emitted by the piezoelectric quartz compensated the charge produced by the radioactive sample. The shorter the time, the greater the amount of charge, and the greater the radioactivity of the sample.
Who discovered radioactive decay?
Marie Curie and her husband Pierre Curie contributed further to the understanding of radioactivity. Their research led to the discovery of two new radioactive elements, polonium and radium, and forced scientists to change their ideas about the structure of the atom.
How did Marie Curie contribute to physics?
Curie was a pioneer in researching radioactivity, winning the Nobel Prize in Physics in 1903 and Chemistry in 1911. Curie never worked on the Manhattan Project, but her contributions to the study of radium and radiation were instrumental to the future development of the atomic bomb.
Who is the mother of physics?
1. Marie Curie. Is considered to this day, to be the Mother of Modern Physics. In 1898, together with her husband Pierre, she discovered the elements of polonium and radio for which she received a first Nobel Prize in Physics in 1903.
Who invented the penicillin?
How did Marie Curie discover uranium?
Marie and Pierre spent time working with pitchblende. Pitchblende is a mineral that is the crystallized form of uranium oxide, and is about 70 percent uranium. (Also used in 1789 in the discovery of uranium). Marie and Pierre discovered not only polonium, but also radium, through their work with pitchblende.
What did Henri Becquerel discover?
When Henri Becquerel investigated the newly discovered X-rays in 1896, it led to studies of how uranium salts are affected by light. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
Is Marie Curie the mother of radioactivity?
Marie Curie was the first truly famous woman scientist in the modern world. She was known as the “Mother of Modern Physics” for her pioneer work in research about radioactivity, a word she coined. She was the first woman awarded a Ph. D.

Who is the father of science?
Galileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the “father of modern astronomy” and the “father of modern physics”. Albert Einstein called Galileo the “father of modern science.”
Why did Alexander Fleming invent penicillin?
Alexander Fleming’s Discovery
After isolating the mold and identifying it as belonging to the Penicillium genus, Fleming obtained an extract from the mold, naming its active agent penicillin. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens.
Who is the father of biology?
How did Alexander Fleming accidentally discover penicillin?
Penicillin discovered
Often described as a careless lab technician, Fleming returned from a two-week vacation to find that a mold had developed on an accidentally contaminated staphylococcus culture plate. Upon examination of the mold, he noticed that the culture prevented the growth of staphylococci.
Who invented amoxicillin?
Amoxicillin was discovered by scientists at Beecham Research Laboratories in 1972. The narrow spectrum of antimicrobial activity of the penicillins, led to the search for derivatives of penicillin which could treat a wider range of infections.
When was nuclear radiation discovered?
In 1896, Henri Becquerel announced the discovery of radioactivity to the Academy of Sciences in Paris after he discovered the radioactive properties of uranium.
What did Rutherford discover?
Rutherford at Manchester, 1907–1919. Ernest Rutherford discovered the nucleus of the atom in 1911.
Who invented 0?
About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it ‘sifr’. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.
Who is the Queen of maths?
Carl Friedrich Gauss one of the greatest mathematicians, is said to have claimed: “Mathematics is the queen of the sciences and number theory is the queen of mathematics.” The properties of primes play a crucial part in number theory.

Is penicillin made from bread mold?
Penicillium mold naturally produces the antibiotic penicillin.
What scientist made penicillin on a large scale?
The simple discovery and use of the antibiotic agent has saved millions of lives, and earned Fleming – together with Howard Florey and Ernst Chain, who devised methods for the large-scale isolation and production of penicillin – the 1945 Nobel Prize in Physiology/Medicine.
What was the first antibiotic ever invented?
Alexander Fleming was, it seems, a bit disorderly in his work and accidentally discovered penicillin. Upon returning from a holiday in Suffolk in 1928, he noticed that a fungus, Penicillium notatum, had contaminated a culture plate of Staphylococcus bacteria he had accidentally left uncovered.
When was penicillin first used for syphilis?
Penicillin was first used in the treatment of syphilis as recently as 1943, and it is now known that the doses originally used were inadequate.
What is a quote that Alexander Fleming said?
“The unprepared mind cannot see the outstretched hand of opportunity.” “Penicillin cures, but wine makes people happy.” “One sometimes finds what one is not looking for.” “For the birth of something new, there has to be a happening.
How did he discover penicillin?
In 1928 Dr Alexander Fleming returned from a holiday to find mould growing on a Petri dish of Staphylococcus bacteria. He noticed the mould seemed to be preventing the bacteria around it from growing. He soon identified that the mould produced a self-defence chemical that could kill bacteria.
