Einstein's Special Relativity Explained Simply - no math



This entire revolution in physics started with a simple thought experiments, in the prolific imagination before Einstein even...

SUMMARY:

Quantum field theory or QFT is the basis of the best theory we have in physics today to explain nearly everything, called the Standard Model of particle physics. What is Quantum Field theory? Why is it...

Quantum theory solved many problems with classical theory - the photoelectric effect solved by Einstein, atomic model solved by Niels Bohr. But quantum theory had a high price - determinism. it introduced...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...

SUMMARY

Albert Einstein was ridiculed when he first published his theory. People thought it was too weird and radical to be real. Einstein wasn’t satisfied with his theory either, because the theory did not...

Summary:

If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which...

SUMMARY

Why does the speed of light change in different media? or Does it? How photons always travel at the same speed, but the speed of light cha

nges.

In 1905 Einstein proposed the theory of special...

SUMMARY

What is Spacetime? Are space and time the same thing? Space was thought to be nothing, an empty void with no matter in it. In 1908, Hermann Minkowski postulated that time could be thought of as a 4th...

Five areas of physics worth remembering: Classical mechanics, energy and thermodynamics, electromagnetism, Relativity, and Quantum Mechanics. Classical mechanics - two main concepts worth knowing. The first is...

Why doesn't anything go faster than the speed of light? Want to see the world through the eyes of a scientist?

...because of Newtonian physics. But Albert Einstein and relativity had other ideas

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

This video delves into Albert Einstein's "miracle year" of 1905, when he published revolutionary papers that changed our understanding of light, atoms, and the universe. Learn about his theories on photons and quantum theory, his proof...

Five experts explore the notion of experimental verification in science, beginning with Karl Popper's famous "falsification criterion". Featured are: Nima Arkani-Hamed (Institute for Advanced Study), Scott Tremaine (Institute for...

The speed of light and black holes. What happens when at the speed of light? What about a black hole? This video explains how time dilations works with very fast relativistic speeds. The equation and the intuition behind the logic.

Particle physicist Nima Arkani-Hamed (IAS) recounts his frustration of the "faster than light neutrinos" story that made media headlines in 2011.

Lesson 14 (Rotation and Torque) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this...

We take lots of things for granted in this world; GPS, the internet and of course particle accelerators (well, maybe not particle accelerators!). However, none of these things would be possible without atomic clocks. In this video Dom...

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

Can a close look at the universe give us solutions to problems too difficult even for a planet-sized computer to solve? Physicist Stephen Jordan considers this question and more in our latest video.

Time is Relative - The Twin Baby Experiment

The History of Physics (Part 2)

We got our feet wet with special relativity, so now let's head to the deep end! Remember in Interstellar when what's his face went down to that one planet and Good Will Hunting was there and they fought and when what's his face went back...

In this video, we learn about the life and contributions of Albert Einstein, the famous scientist who revolutionized our understanding of the universe. From his early curiosity about mathematics and electricity to his groundbreaking...
