How Does A.I. Handle An Astrophysics Final Exam?

This video is from Cool Worlds. Artificial Intelligence (A.I.) systems have been rapidly improving in recent years and Chat-GPT3 took the world by storm in Nov 2022. As smart at it may be, how does it compare to a typical undergraduate student sitting an introductory astronomy exam? Let’s find out! Sponsored by Ground News, head […]

Why Did Quantum Entanglement Win the Nobel Prize in Physics?

The Nobel prize in physics is typically awarded to scientists who make sense of nature; those whose discoveries render the universe more comprehensible. But the 2022 Nobel has been awarded to three physicists who revealed that the universe is even stranger than we thought thanks to Quantum Entanglement

The Equation That Explains (Nearly) Everything!

The Standard Model of particle physics is arguably the most successful theory in the history of physics. It predicts the results of experiments with a numerical precision unmatched by any other branch of science, and it does so almost unfailingly. The theory is encapsulated in a single equation known as the Standard Model Lagrangian. Today […]

Will Constructor Theory Rewrite Physics?

With my interesting in quantum computing, I have spent a lot more time than usual looking at videos like this. The people behind the greatest leaps in physics – Einstein, Newton, Heisenberg, all had the uncanny ability to see the fundamentals – see the deepest, underlying facts about the world, and from simple statements about […]

New Results in Quantum Tunneling vs. The Speed of Light

In a race, who would win: quantum tunneling or the reigning champ, the speed of light? Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way. New efforts in quantum tunneling – both theory and experiment – show that superluminal motion may […]
