Part 2 in our quantum reality series is out now: youtu.be/-_8apfiiTR4. I talk to Simon Saunders, Antony Valentini & Angelo Bassi to explore 3 interpretations of QM – many worlds, pilot wave & objective collapse.
Here’s a clip where I try to explain decoherence.

Just released another new film on our new YouTube channel: youtu.be/sivQ-jbZ2oM. It’s the first in a 3-parter on quantum mechanics. In this first one I look at the early observations that shook our understanding of physics.

My second YouTube video is out now! In this one I'm looking inwards in an attempt to unbaffle my own brain. I talk to @ForresterGilly and Mike Gazzaniga about the two hemispheres of the brain, and how brain asymmetry evolved. Watch here:

Time travel to the future is possible if we slow time down. This is called time dilation and it's a real thing. Matthew McConaughey does it in Interstellar. I discuss the trickier time travel to the past on my new YouTube channel. See: youtu.be/c63XUCGg9hM
