Serious question: why do we keep repeating this experiment? Not that I mind, I just am curious why do we keep building bigger and bigger vacuum chambers just to drop a feather and a hammer over and over.
Before they pump the air out in the video, the presenter explains what the facility was made for and is currently used for.

What? No! I don't know about you, but I would have a silly grin on my face too if I actually got to see this experiment live - I mean it's such a classic result - we've all been told that this is what would happen, but very few of us actually get to see it. It's like the experience of seeing the moons of Jupiter the first time that you look at it through a telescope - yes, you know the moons are there, you've even se…
I was giddy just watching this video! I'm sure his joy was genuine. It's just amazing to see feathers fall straight and bounce(!) when they hit the ground.

>Brian Cox, the presenter and avowed scientist, I think you mean "Brian Cox: Professor of High-energy Particle Physics, member of the High Energy Physics group at the University of Manchester, and the ATLAS experiment at the Large Hadron Collider at CERN (who also presents popular science programmes in the UK)" I think his career as a scientist deserves a little more recognition than "avowed". And, as for his career…
Sorry; I have every respect for Brian Cox, unlike others on this thread. I think I'm merely using totally the wrong word.

I just watched this today - I've studied physics at Uni - I've done many experiments and known this result for a long-long time. However, this was actually the first time I've seen it myself. It is awesome to see something so un-intuitive but so well known actually occurring - like if you could actually see quantum tunnelling happening. If you don't find the world awesome then doing physics has got to be a pretty har…
This does quite a nice job of it, for me :) https://www.youtube.com/watch?v=GcDshWmhF4A
