Professor Hans Bethe explains superconductivity in his lecture titled " My Relation To Early Quantum Mechanics" at MIT November 21, 1977.

Professor Brian Greene explains Einstein's theory of gravity.

I have never met a man so ignorant that I couldn't learn something from him. - Galileo Galilei

Beautiful slow-motion surface tension demonstration.

Happy Birthday to one of the titans of Quantum Mechanics, Paul Dirac, born 123 yrs ago today. Dirac is one of the pioneers of Quantum mechanics and the first physicist to predict the existence of anti-matter. He received the 1933 Nobel Prize in Physics together with Erwin Shcrödinger.

People like us who believe in physics know that the distinction between past, present, and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion. — A. Einstein (1879-1955)

The physics of light refraction through broken glass

The double slit experiment was pivotal in demonstrating the wave-particle duality of light and matter. When particles like electrons are fired through slits, they produce an interference pattern typical of waves, not particles.

"Tesseract" can mean many things: an OCR engine, a 4D hypercube in geometry, the Space Stone’s container in Marvel, a British metal band, or a premium e-scooter by Ultraviolette. One word, many dimensions.

The last known picture of Albert Einstein, taken in March 1955, in front of 112 Mercer Street.

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff. - Carl Sagan

Demonstration of double pendulum chaos

"The heart of physics is trying to understand what's real." -Richard Feynman

“What we know is a drop, what we don't know is an ocean.” - Isaac Newton

You don't like it? Go somewhere else! as said by Richard Feynman in one of his lectures at University of Auckland.

In order to see the true nature of gravity we have to remove the air.

120 years later, a thermodynamics puzzle is cracked, Professor José María Martín-Olalla showed that the Nernst theorem about how entropy (disorder) behaves near absolute zero is actually part of the second law of thermodynamics. Even Einstein thought it was a separate rule. Credit: SciTechDaily

If you want to master something, teach it. - R. Feynman

As mentioned in Sir Isaac Newton's 1676 letter to Robert Hooke

"Blind obedience to authority is the greatest enemy of truth." - Albert Einstein

A photograph (colorized) of A. Einstein and R. Oppenheimer is having a conversation at Einstein's office in Princeton, N.J., ca. 1947.

Leonard Susskind talks about how Richard Feynman influences him as a physicist.

Aristotle's laws of motion. In Physics he states that objects fall at a speed proportional to their weight and inversely proportional to the density of the fluid they are immersed in this is a correct approximation for objects in Earth's gravitational field moving in air or water.

You're unlikely to discover something new without a lot of practice on old stuff. - Richard Feynman

I was an ordinary person who studied hard. There are no miracle people. -- R. Feynman

Polarization of Light.

It is the supreme art of the teacher to awaken joy in creative expression and knowledge. - Albert Einstein

You cannot teach a man anything, you can only help him to find it within himself. Galileo Galilei

Sir Isaac Newton's 'Trinity College notebook' page written somewhere between 1661 and 1665, when he was an undergraduate at that same college.

Quantum mechanics pioneers Niels Bohr and Max Planck photographed in front of a chalkboard, ca. 1930.

If you think you understand quantum mechanics, you don't understand quantum mechanics. -Richard Feynman

When you change the way you look at things, the things you look at change. - Max Planck (1858 - 1947)

"Creativity is intelligence having fun." - A. Einstein (1879 - 1955)
