Some of those are just definitions. Not sure what's the usefulness of det(A) = |A| or c=λf, it's not like one would need to look that up.

It's not only rear ending. The main road near my house has a sharp left turn with a sign on the side of the road. I occasionally get a BRAKE! warning there, probably because AEB mistakes that sign for a car in front of me. On a wet roa

Having done Couch to 5K, I can say 9 weeks is too short. I understand that a longer, more realistic time frame would mean fewer people will attempt it, but such quick growth makes injuries more likely. Lungs and heart adopt faster than liga

My point is that if all I need is to convince my audience, I may be able to make them believe the flawed proof. In this example the flaw is intentionally obvious, but there are other examples where the flaw is more subtle.

The problem with this formulation is that one can convince the audience that something is right when it isn't. Example: 31 is prime, 331 is prime, 3331 is prime, 33331 is prime, ... 33333331 is prime, therefore 333333331 must be prime

Everything you know is easy for you. For others, there's opportunity cost. The time one spent on learning Peano axioms is the time one could have spent on learning something more useful, say, linear algebra.

I look at math the same way as at physics, where rigorous proofs are not possible. The difference only matters to the few people who do it professionally. I know I can dig deeper all the way down to axioms if I choose so, but realistically

It takes considerably more to kill someone than to break the skin. Maybe if you are laying on your back and the falling bullet hits the carotid artery, but this is a really contrived example.

Let's take a common 9 mm round with muzzle velocity of 1,100 fps. When fired at 87 degrees, horizontal velocity component is 1,100 fps * cos 87 deg = 57 fps. It will be much less than that on the way down due to air resistance througho

Let's do science then. Terminal velocity of a falling 9 mm bullet is 219 fps, .223 bullet falls at 244 fps. [1] To perforate the skin and enter the underlying subcutaneous tissue and muscle, a minimum velocity in the order of 230 fps i

Source? In the case Mythbusters mentioned, the person killed by falling bullet was about a mile away, hence those bullets were fired at a lower angle.

by sobriquet9 4y ago
See my other comment. Mythbusters found the same thing, that bullets fired at low elevation remain dangerous, while bullets fired at high elevation (close to vertical) come down at a much lower velocity, not sufficient to kill a person.

I don't see a contradiction between what I said and what Mythbusters have found [1]. > In the case of a bullet fired at sufficiently close to a vertical angle to result in a nonballistic trajectory, the bullet would tumble, lose its
