Physics is the fundamental science that explains how the universe works. Its principles shape every part of our daily routines & drive modern civilization. Mathematics (eqn) is the essential language & logical backbone of physics.

Here are the 3 most famous physics questions.

Today is October 25.

It's the birthday of Henry Norris Russell 🎂

He is best known for showing the relationship between a star's brightness and its spectral type, called the Hertzsprung-Russell diagram (HR diagram).

An asteroid 1762 Russell is named after him.

It's birthday of Wilhelm Eduard Weber, best known for his pioneering work in electromagnetism

With Gauss, he constructed 1st electromagnetic #telegraph

He was 1st to use c for the speed of light

The SI unit of magnetic flux, weber (Wb), is named after him

Today is October 23.

It's the birthday of #FelixBloch , one of the founders of solid-state physics

He earned his PhD at the University of Leipzig under #WernerHeisenberg

He received the 1952 physics #NobelPrize in Physics.

He was CERN's first Director-General.

Today marks the 193rd birthday of #AlfredNobel 🎂

He worked on various important contributions & inventions to science, most famous was #dynamite

He held 355 patents during his lifetime.

In his 1895 will signed in Paris, he bequeathed his fortune to establish the #NobelPrizes

Today marks the 135th birthday of Sir #JamesChadwick , who discovered the neutron.

For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, the #NobelPrize in Physics in 1935, the Copley Medal in 1950 and the Franklin Medal in 1951.

42 years ago, #OTD the genius #PaulDirac left us after revolutionizing physics with silence.

One of the founders of quantum mechanics & quantum electrodynamics, he was the 1st truly modern theoretical physicist.

He shared the 1933 #NobelPrize in Physics with #ErwinSchrödinger

[Cosmological Astrophysics @CosmoAstrophy]

Let me introduce you to a New Zealand man who won the Nobel Prize in chemistry in 1908 & then he performed his most famous work & found nucleus in the atom.

It's death anniversary of #ErnestRutherford

The chemical element #rutherfordium (atomic number 104) was named after him.

Today marks the 116th birthday of the renowned Indian astrophysicist #SubrahmanyanChandrasekhar

#CarlSagan praised him: "I discovered what true mathematical elegance is from Chandrasekhar."

The richest man @elonmusk named one of his sons (the middle name) Sekhar after him.

Previous year, #OTD , one of the world's most renowned physicists, #ChenNingYang was died. He shared the 1957 Nobel prize for physics with Tsung-Dao Lee

They were awarded the Nobel prize for work that overthrew the widely accepted parity laws.

Today is October 17.

It's the death anniversary of #GustavRobertKirchhoff

In 1845, while still a student, he formulated electrical circuit laws, which are now ubiquitous in electrical engineering.

#MaxPlanck, the father of Quantum Theory, was one of his students.

[Cosmological Astrophysics @CosmoAstrophy]

#OTD in 1843, the theory of #quaternions was born when Sir #WilliamRowanHamilton was on his way to the Royal Irish Academy where he was going to preside at a council meeting. As he walked with his wife, the concepts behind quaternions were taking shape in his mind.

[Cosmological Astrophysics @CosmoAstrophy]

By exclaiming "Physics works, and I'm still alive!" right after a dangerous-looking demo stopped inches from his face, professor Walter Lewin reassured his students that the laws of physics are absolute, predictable, and trustworthy.

Today is October 15.

It's the birthday of #EvangelistaTorricelli, the first man to create a sustained vacuum

He was a student & strong supporter of Galileo.

He solved the suction pump puzzle and discovered the barometer.

The #torr, a unit of pressure, is named after him.

[Cosmological Astrophysics @CosmoAstrophy]

Today is October 14.

It's death anniversary of Walter Maurice Elsasser

In 1946, he presented the first mathematical model for the origin of the Earth's magnetic field and, today, he is considered the "father" of the presently accepted dynamo theory.

[Cosmological Astrophysics @CosmoAstrophy]

#OTD in 1985, at the Fermi National Accelerator Laboratory in Illinois, the 1st observation was made of proton-antiproton collisions by the Collider Detector at Fermilab (CDF) with 1.6 TeV center-of-mass energy.

Total 23 collisions were detected in October 1985.

Congratulations to those who won this year's Nobel prizes

Everyone dreams to get it but a true fact - If you discover or invent, there is more chance that you won't get it.

Since the first awarded in 1901, the conferment of the Nobel Prize has engendered criticism & controversy

[Cosmological Astrophysics @CosmoAstrophy]

Today is October 11.

It's death anniversary of #JamesPrescottJoule, one of the greatest scientists in the history of physics.

In 1841, he discovered what became known as Joule's Law.

The SI derived unit of energy, the joule, is named after him.

Today is October 10.

It's the birthday of #HenryCavendish 🎂

#Newton had published his law of gravitation in 1687, but he didn't make any attempts to determine G. It was Cavendish, who, in 1798, experimentally measured G & then calculated the density (hence mass) of the Earth.

Today is October 9.

It's the birthday of Max Theodor Felix von Laue 🎂

Many scientists say, his 1912 discovery of X-rays diffraction by crystals was the main turning point of modern science.

This discovery earned Laue the 1914 Nobel Prize in physics.
