Hello! So I have been quiet of late when it comes to videos because a lot of other things have been going on... This is why I use patreon on a per video basis, rather than per month so you don't have to support when I don't make videos.

This is a video I've been thinking about making for years, ever since I made the Uranium documentary. There's something I've been meaning to say about the whole discovery of radioactivity and its development into a the most powerful technology we've ever developed. This is what I was thinking as we finished up the documentary but I was never able to express myself in that film as clearly as this. I hope you enjoy.

How Neutrons Changed Everything

Without neutrons, harnessing nuclear energy would be impossible.

I always thought of the characters in our story as the scientists and maybe the uranium nucleus itself. It was only through making the documentary that I realized the real hero of the story is the neutron. Without a neutral nuclear particle, it would be virtually impossible to release the energy from the nucleus. But with it, and the idea of a chain reaction, nuclear energy went from science fiction to reality. That is something I had not grasped as clearly before and it motivated me to make this video. Filmed by Raquel Nuno.

Hi Derek! I guess you haven't updated your Wall of Thanks yet. No biggie, but I've been raving about Veritasium for such a long time that I kinda want people to know that I support the channel ways other than talking about it. ☺ (I'm not actually a new supporter, but I recently upped my level. Maybe that produced a notification that some system somewhere didn't recognise. Or maybe you've just been busy—hope your other endeavours are going well. ☺) I'm actually really excited to see a new Veritasium video, and it turns out this is one of those areas where I didn't know how much I didn't know. Thanks!
