I don't doubt that this guy was rightly convicted but the error rate on finger print matches can be above 10% for experienced analysts, depending on who does the analysis of error. If I had the...

To Cornish Jack. I mostly agree with you, and I use the Cornish flag in some posts as my dad was Cornish, from Cawsand. But the red saltire is associated with St Patrick, and the Welsh flag is not...

momentum same in both directions

It always was the same. It's the kinetic energy that kills you.

Imagine a ten pound gun firing a one ounce bullet at 1600 feet per second. It will recoil at ten feet per second. Momentum is 10*10...
