Electrons DO NOT Spin
Quantum mechanics has a lot of weird stuff - but there’s thing that everyone agrees that no one understands. I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the...

Loop Quantum Gravity Explained
The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general...

Could the Higgs Boson Lead Us to Dark Matter?
The discovery of the Higgs boson ten years ago in the Large Hadron Collider was the culmination of decades of work and the collaboration of 1000s of brilliant and passionate people. It was the final piece needed to confirm the standard...

Why String Theory is Wrong
There’s this idea that beauty is a powerful guide to truth in the mathematics of physical theory. String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong? Hermann Weyl once said,...

Is Quantum Tunneling Faster than Light? | Space Time | PBS Digital Studios
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...

Are Virtual Particles A New Layer of Reality?
Sometimes our mathematical hacks point to strange new aspects of reality. For example Max Planck used a quantization trick to figure out the spectrum of light emitted by hot objects. The quantization part of his math trick was meant to...

You Suck at Skipping Rocks
Most of us are stoked if we can get a stone to skip more than 3 or 4 times. The world record holder at skipping stones has 88 skips. Here's why science says that number is way too low.

Salton Sea Lithium Deposits Could Help EV Transition, Support Economically Devastated Area
The demand for electric vehicles is surging in the U.S., sparked in part by the Biden administration’s Inflation Reduction Act and the subsidies it offers. But a looming supply shortage of lithium threatens to stall the EV transition....
