In 1903, Marie Curie became the first woman in France to earn a PhD in physics.

The professors who reviewed her doctoral thesis on radiation declared it “the greatest single contribution to science ever written”.

It’s time for a thread on the “Mother of Modern Physics”👇👇👇
1) Curie (1867-1934) was born in Warsaw, Poland, the youngest of five children.

Although Marie was a prodigy in literature and math, she was unable to attend university in Poland because she was a woman.
2) Curie thus became a governess until age 24, when she had saved enough to move to Paris.

There, she studied physics and mathematics at the Sorbonne, one of the most prestigious universities.

While studying, she met Pierre Curie, a physics professor, whom she married in 1895
3) The same year Curie was awarded her PhD (1903), she also became the first woman to win a Nobel Prize.

She won the Nobel for her discovery of a new chemical element: Polonium.

She was awarded the prize jointly with her husband Pierre and fellow scientist, Henri Bacquerel.
4) Marie’s breakthrough came while working with a sample of uranite, a mineral which contains radioactive uranium.

She noticed the sample was far more radioactive than expected.

Curie was convinced that another highly radioactive chemical must be present in the uranite…
5) Marie and Pierre were eventually able to extract a chemical 330 times more radioactive than uranium from the uranite.

They named this element “Polonium”, after Marie’s country of birth.
6) While isolating polonium, the couple noticed an even more radioactive black liquid.

They believed there must be a second undiscovered and highly radioactive chemical present…

They called this unknown element radium.
7) They were, however, unable to isolate the element before Pierre’s death in a carriage accident in 1906.

Marie continued their work alone and was able to isolate radium in 1910.

For this discovery, she was awarded her second Nobel Prize in chemistry.
8) Curie also found that radium could be used to treat tumors…

Her breakthroughs in radioactivity underlie many modern uses of radiography.
9) During World War I (1914-1918), Curie became Director of the Red Cross Radiology Service.

Her contributions were no less remarkable than her peacetime breakthroughs.

Curie developed mobile x-ray stations which were used to diagnose and treat battlefield injuries…
10) These mobile x-ray stations became known as “petites Curies” (Little Curies in French).

An estimated one million soldiers were treated using these machines!
11) Bonus Fact: Marie and Pierre’s first daughter, Irene, followed in her parents’ footsteps…

Irene was awarded the 1935 Nobel Prize in Chemistry—together with her husband Frederic Joliot—for their discovery of artificial radioactivity.

(Marie and Irene are pictured below.)

Imagine a giant cloud. A really giant cloud. Like, trillions of miles wide. Now, imagine it is in outer space, made out of dust and gas.

What you may (or may not) be imagining is called a nebula.

It’s time for a thread👇👇👇
1) Nebulae (the plural of nebula) are closely associated with the birth and the death of stars.

Some nebulae are nicknamed “star nurseries” because they are regions where new stars are being born.
2) Stars form when gravity pulls together the dust and gas (mostly hydrogen and helium) that make up the nebula.

Other nebulae are formed from the elements thrown out by the explosion of a dying star, like a supernova.

In 1765, Britain implemented a tax on cider production to help fund its debts.

The tax led to riots, the catchy quote “give me liberty, or give me death”, and ultimately, the American Revolution…

It’s time for a thread on the Stamp Act👇👇👇
1) During the Seven Years’ War (1756-1763), Britain defeated France for control of North America. But the victory left Britain deeply indebted.

When a domestic tax on cider production led to riots, Britain looked for its North American colonies’ help in replenishing its coffers. Image
2) Indirect taxes were already levied on the colonies through duties on imports and exports.

Britain now levied its first direct tax on North American colonists with the Stamp Act, which passed Parliament in Spring 1765.

In 1918, as World War I was coming to an end, a virus began rapidly spreading amongst Allied troops. When the soldiers returned home, they brought the disease with them...

This was the start of the deadliest pandemic in modern history.

Time for a thread on the Spanish Flu👇👇👇
1) First, let’s clarify a common misconception. The Spanish Flu was NOT from Spain.

The name actually comes from the fact that Spanish media was the first to cover the outbreak.
2) Countries involved in World War I had wartime censors who blocked news of the flu to keep up morale.

Spain, a neutral nation, had no media censorship.

They were, thus, the first country to widely report on the virus, especially after their king, Alfonso XIII, contracted it

One of history’s most influential thought experiments involves a radioactive zombie cat, letters to Albert Einstein, and multiple Nobel Prizes...

It's time for a thread on Schrödinger’s Cat👇👇👇
1) Throughout the 18th and 19th Centuries, Newton’s Laws were the basis of physics.

In the early 20th Century, physicists realized that very tiny things did not obey Newton’s Laws.
2) While Newton’s Laws still explained the motion of a ball or an apple, they could not be used to explain the nature of atomic and subatomic (super small) particles.

Thus, the field of quantum physics was born…

You’ve heard of the Manhattan Project…

But did you know that it featured secret cities, some of the world’s most famous scientists, and $22 billion in government funding?

Time for a thread on the most consequential government project in history👇👇👇
1) In 1939, US President Roosevelt received a letter written by physicist Leo Szilard and co-signed by none other than Albert Einstein.

The letter warned that Germany was building an atomic bomb and suggested that the US should launch its own nuclear program.
2) So, the US government began supporting nuclear research at universities.

The goal was initially just to see whether it was even possible to build a nuclear weapon.

But after the bombing of Pearl Harbor, efforts ramped up… (This was when the US officially joined WWII.)
