PBS: Space Time | Quantum Entanglement and the Great Bohr-Einstein Debate

Albert Einstein strongly disagreed with Niels Bohr when it came to Bohr’s interpretation of quantum mechanics. Quantum entanglement settled the argument once and for all. Einstein argued that elementary particles maintained their intrinsic values whether they were being observed or not. Bohr believed that in observing such particles we collapsed a wave function of probabilities. …

Physics Girl: Why do mirrors flip horizontally but not vertically?

Ever wondered why mirrors appear to flip images horizontally but not vertically? Physics Girl got the answer. If you wrote the word apple down on a piece of paper and then flipped it vertically to face the mirror, rather than horizontally, it would still read apple, albeit upside down, of course.  

Perimeter Institute for Theoretical Physics: Testing General Relativity with Black Holes

Using the Event Horizon Telescope, a research team including Avery Broderick and Tim Johannsen of Perimeter Institute and the University of Waterloo has demonstrated a new method for testing the theory of general relativity using black holes.  

PBS: Space Time | Is There a Fifth Fundamental Force? + Quantum Eraser Answer

Has a fifth fundamental force been discovered and how will this effect our understanding of the universe? A laboratory in Hungary has has witnessed a startlingly strange reaction between Beryllium-8 atoms. It seems to point to the existence of a fundamental force beyond the four we already know. And this new force may have something …

TED-Ed: What is a vector?

Physicists, air traffic controllers, and video game creators all have at least one thing in common: vectors. But what exactly are they, and why do they matter? David Huynh explains how vectors are a prime example of the elegance, beauty, and fundamental usefulness of mathematics.  

TED-Ed: How the Königsberg bridge problem changed mathematics

You’d have a hard time finding the medieval city Königsberg on any modern maps, but one particular quirk in its geography has made it one of the most famous cities in mathematics. Dan Van der Vieren explains how grappling with Königsberg’s puzzling seven bridges led famous mathematician Leonhard Euler to invent a new field of …

University of Manchester: In Conversation with Professor Brian Cox at National Gallery

One of the leading public science educators of our time Prof. Brian Cox in a conversation with comedian and the scientific curious Robin Ince – who together have a podcast called the Infinite Monkey cage – described as a witty, irreverent look at the world through scientists’ eyes.  

Life Noggin: How Long Would It Take To Fall Through The Earth?

Falling through the Earth would be a wild ride (assuming you’d survive)! How long would the trip take?

Vox: Why Elon Musk says we’re living in a simulation

You may like playing The Sims, but Elon Musk says you are the Sim. on Musk thinks we are living in a simulated reality. Nick Bostrom think those chances are more around 20 percent. The chances of human kind participating in a simulated reality is broken down into three options: 1) humans go extinct before …

PBS: How the Quantum Eraser Rewrites the Past | Space Time

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and our greater universe?  

Numberphile: Paper Calculator

Comic book genius Jason Shiga shows us a calculator made of paper. We’ve got more coming from Jason which will explain WHY he made this (besides the fact it is just cool!)  

Perimeter Institute for Theoretical Physics: Natalie Panek: Inspiring Future Women in Science

Rocket scientist Natalie Panek shares stories from her career in aerospace engineering and lessons learned in the pursuit of a STEM career during the Inspiring Future Women in Science conference at Perimeter on April 15, 2016.  

TED-Ed: Why the metric system matters – Matt Anticole

For the majority of recorded human history, units like the weight of a grain or the length of a hand weren’t exact and varied from place to place. Now, consistent measurements are such an integral part of our daily lives that it’s hard to appreciate what a major accomplishment for humanity they’ve been. Matt Anticole …

PBS: Is Quantum Tunneling Faster than Light? | Space Time

Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. This is only one way that quantum mechanics challenges our perception of reality. Matt dives into these counter-intuitive ideas and explains the bizarre phenomenon known as quantum tunneling in this episode of …

The Royal Institution: What is Zero? Getting Something from Nothing – with Hannah Fry

Is zero really a number? How did it come about? Hannah Fry tells the story of how zero went from nothing to something. Once upon a time, zero wasn’t really a number. Its journey to the fully fledged number we know and love today was a meandering one. Today, zero is both a placeholder, and …
