Einstein's Miracle Year: Groundbreaking Discoveries of 1905
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...

Why Did Einstein Hate Randomness?
How random are things, really? Well, at the tiny level of photons, randomness might be key to their existence. Einstein could not accept this and famously held the paraphrased opinion that, ‘God does not play dice with the universe’. In...

Asking The Right Questions
Nobel Laureate Antony Leggett describes his gut feeling that cosmology is ripe for a major revolution, and describes why he is not particularly sympathetic to the field of "quantum cosmology".

The de Broglie Equation and Why There Is No Wave-Particle Duality
The wave-particle duality seems to used all the time to explain quantum mechanics to the public, but it is one of my pet peeves. It represents an outmoded way of thinking (old quantum theory), which is replaced by our current...

Is randomness in quantum theory an illusion?
God does not play dice with the universe' Einstein famously argued. Yet contemporary physics embeds just such dice playing at the core of its account. Is the universe really unknowable even to itself? Or as Einstein implied is this...

The most beautiful idea in physics - Noethers Theorem
The proof and maths of Noethers theorem: There are two ways to approach Noethers theorem that I know of. The most common is through Lagrangian mechanics- where the proof is surprisingly simple but unfortunately quite opaque . The other...

A problem with Bohmian Mechanics Contextuality
Contextuality might mean that there are no alternatives to Quantum mechanics that are sensible. Given Quantum isnt sensible either, there may just not be any sensible theories at all.

Quantum Mechanics | The Act of Measurement
The act of measurement in quantum mechanics causes "collapse of the wavefunction". Here, I explain what is meant by measurement in the discipline of quantum mechanics.

Quantum Entanglement and the EPR Paradox
What is entanglement really? And why is it that its a uniquely quantum phenomena? Bohmian mechanics stuff: In Bohmian mechanics, you still have superpositions, they just mean something very different. A Bohmian mech particle only has one...

Eric Weinstein: Economic Thinking In A Fallible World
By Marshall Auerback The philosopher Karl Popper argued that we cannot know empirical truths with absolute certainty. According to Popper, even scientific laws can't be verified beyond a shadow of a doubt. They can only be falsified by...

Quantum Randomness
How is quantum randomness anymore mysterious than the randomness of a coin flip? Youll see. The homework questions and extra readings are below: The questions: 1. What if there are three slits and you only have a detector at one. What...

Schrodinger equation - Derivation and how to use it
In this video we see how the Schrodinger equation comes out very simply from the conservation of energy. First. Throughout these 2 videos, I kept talking about predicting the future, and that if you know the present state, you can...

Why Cant You Use Quantum Mechanics To Communicate Faster Than Light?
The EPR paradox, that we met in a previous video, tells us 2 entangled particles can effect each other no matter now far away they are. But then why cant we use them to send instant messages across the universe? Einsteins relativity...
