34:00, why is the threshold energy not equal to twice the rest mass of the w particle? My intuition tells me that if 2 w particles are created then the minimum energy for the reaction to occur (leaving 2 w particles) should be 2mc^2 where m is the mass of a w particle. Thanks

Hi Dr. We can see lots of books in the video background.Would you mind uploading a video on your bookshelf tour?
33:04 So Pw+=Pw-=0 because they should have the same velocity and they should be equal oppesits so thay cant be nothing els but 0 ?
Yes that's correct!

Yes you're right, the thing we calculated here was the threshold energy per particle, not the total energy.
