BRADY HARAN: Hey there, everyone.Today's video is about Richard Feynman--a lot of people's favorite scientist--and safe breaking.But I just wanted to point out at the start that most safes,or secure filing cabinets, actually have one dial.And if you've got a three number combination, forexample, you'll turn that dial in one direction, then theother direction, and then back in the other direction.And that's how you open it.But the mock up that we've used in this video--and it is a mock up, I can assure you.It's about as far from a safe as you could get.We've used three dials.That kind of makes things a bit more visual, a bit easierto understand looking at it in that way.But in most cases, the sort of ...
