A New Era in Astronomy: NASA’s James Webb Space Telescope

Dr. Amber Straughn of NASA provides a behind-the-scenes look at the James Webb Space Telescope in this public lecture at the Perimeter Institute for Theoretical Physics.  

Ted-Ed: What is entropy? – Jeff Phillips

There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course …

PBS: Space Time | Are We Living in an Ancestor Simulation? ft. Neil deGrasse Tyson

The idea that our reality is a simulation is not as far-fetched as you may think. Many philosophers, scientists, and tech-billionaires are seriously considering not just the possibility but the high probability that our civilization may be a program being run by another, more advanced alien civilization.  

The Oh My God Particle | Space Time

This episode of PBS Space-Time features the God Particle! Cosmic rays aren’t actually rays at all, but atomic nuclei traveling at close to the speed of light. Typically they are low in energy and are easily deflected by other particles, but on rare occasions an incredibly powerful atomic nuclei strikes the Earth’s surface. The largest …

Precipitation3 shows how chemistry is beautiful

This is how chemistry should be taught in our schools. ‘Precipitation3’ is a short film by ‘Beauty of Science’ shot with a microscope showing us several beautiful chemical reactions where liquid solutions become solids or precipitates. There are eight reactions in total: 1. Nickel chloride and sodium carbonate produce nickel carbonate precipitation. 2. Iron(III) chloride …

PBS Space Time: Time Crystals!

In this episode of the Space Time Journal Club Matt discusses how two independent research teams created their own Time Crystals, a form of matter that breaks time translational symmetry and could be used in quantum computers.  

PBS Space Time: Superluminal Time Travel + Time Warp Challenge Answer

By choosing the right path and the right reference frames, any superluminal motion can lead to information or objects returning to their origin before they depart. Matt O’Dowd will show you how to navigate such a path.  

ZALUSKArt: Frozen soap bubbles

Soap bubbles are chic, frozen bubbles are much better, however. They don’t last very long, but it’s a wonderful spectacle when ice crystals form on the bubble surface in front of the camera lens.  

Perimeter Institute for Theoretical Physics: As We Enter a New Quantum Era: Michele Mosca Public Lecture

In his public lecture at Perimeter Institute on Oct. 5, 2015, Michele Mosca (Institute for Quantum Computing, Perimeter Institute) explored quantum technologies – those that already exist, and those yet to come – and how they will affect our lives.  

Science Magazine: Breakthrough of the Year, 2016

The discovery of ripples in spacetime—gravitational waves—shook the scientific world this year. It fulfilled a prediction made 100 years ago by Albert Einstein and capped a 40-year quest to spot the infinitesimal ripples. But instead of the end of the story, scientists see the discovery as the birth of a new field: gravitational wave astronomy. …

CERN ALPHA first ever optical spectroscopy of a pure anti-atom

Researchers at CERN in Geneva has for the first time investigated the properties of antimatter atoms. The ALPHA experiment at CERN’s antimatter factory reports first ever optical spectroscopy of a pure anti-atom.  

TED: Math is the hidden secret to understanding the world | Roger Antonsen

Unlock the mysteries and inner workings of the world through one of the most imaginative art forms ever — mathematics — with Roger Antonsen, as he explains how a slight change in perspective can reveal patterns, numbers and formulas as the gateways to empathy and understanding.  

PBS: Space Time | What Happens at the Event Horizon?

What really happens when you approach the event horizon of a black hole? What do you see when you actually cross it? Matt shows you an elegant tool for understanding this mysterious region of spacetime.  

PBS: Space Time | Pilot Wave Theory and Quantum Realism

There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it’s de Broglie-Bohm pilot wave theory.  

Michael Cates: Fluids That Stop Flowing When You Push Them Too Hard

In his public lecture at Perimeter Institute on Nov. 3, 2016, Michael Cates (Lucasian Professor of Mathematics, University of Cambridge) explains this peculiar form of “bulletproof custard” with a few equations, plenty of diagrams, and even some hands-on demonstrations.  

PBS: Space Time | Did Dark Energy Just Disappear?

Did all of dark energy just vanish? A team of scientists have just analyzed new data and claim that we need to completely rethink its existence. PBS Space Time is once again talking about dark energy. A team of researchers has announced a new analysis of updated supernova data. They claim that the data are …
