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.

They’re actually drawn by a young artist friend of my producer’s in India. There are always copyright issues with photos of famous people so we’re just erring on safety.

🧪 Thanks to everyone who’s already subscribed to my new YouTube channel, Unbaffled. Nice to see that the first three films have already been watched by half a million people around the world. Lots more to come.

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 new YouTube channel
(www.youtube.com/@UnbaffledSc...) seems to be going very well so far, after its first week. But a typo was found in an equation😱 so I had to post this short apology.
I mean, the shame..

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

My new YouTube channel, "Unbaffled", is here. It's where I'll be exploring the biggest ideas in science.
Our founding principle is that science doesn’t have to be baffling.
The first video (on time travel) is here:
