Why wouldn't it be legal?

Did Christopher Hitchens change his mind about waterboarding?

Yes, I did watch some of his interviews on related subjects, but couldn't find any relevant statements one way or the other. But I couldn't watch all that many; as Gwern points out above, many were probably not recorded.

I think I explain this in the last section? There are several statements he makes that at least imply he doesn't consider it torture, and I couldn't find any with the opposite implication.

Don't Eat Honey

97% of years of animal life brought about by industrial farming have been through the honey industry (though this doesn’t take into account other insect farming).

 

This number is nonsense by the way. If you click through to the original source you'll see that it  excludes shrimp and other marine animals.

I'm switching to a password manager and wanted a master password that's short enough it's not annoying to type, so I came up with a scheme that can potentially improve on passphrases, keeping the memorability while becoming shorter.

I wonder if there's a much simpler explanation: Simon Browne grew up with an internal monologue, but the trauma of the event caused it to go away.

Many normal, conscious people don't have one, but they're used to it. Suddenly losing yours would be extremely alien, and surely "I'm no longer conscious" would be a natural conclusion.

Rational Agents Cooperate in the Prisoner's Dilemma
Isaac King4mo10

The offer is still open, but the point is that it's positive expected value for both me and a causal decision theorist when the CDT agent is making the choices themselves, which I believe implies irrationality on their part. I'm not interested in playing against someone who's "cheating" by generating their sequence some other way, that defeats the point. :)

Well that explains why you got the wrong answer! Springs, as you now point out, work opposite the way gravity does, in that the longer a spring is, the more energy it take to continue to deform it. (Assuming we mean an ideal spring, not one that's going to switch to plastic deformation at some point.) So if we were talking about springs, you would be correct that the most efficient time to teleport the spring longer would be when it's already as long as possible.

But we are not talking about springs, we are talking about gravity, which works differently. (Not only is the function going in a different direction, but also at a different rate. Gravity decreases as the inverse square of the distance, whereas spring force increases linearly with distance.) So your "simplification" is just wrong. You stated:

A weird consequence. Say our spaceship didn't have a rocket, but instead it had a machine that teleported the ship a fixed distance (say 100m). (A fixed change in position, instead of a fixed change in momentum). In this diagram that is just rotating the arrows 90 degrees. This implies the most efficient time to use the teleporting machine is when you are at the maximum distance from the planet (minimum kinetic energy, maximum potential). Mathematically this is because the potential energy has the same quadratic scaling as the kinetic. Visually, its because its where you are adding the new vector to your existing vector most efficiently.

This is false. It takes more energy to move an object up by 1 meter on the surface of Earth than it does a million km away, because gravity gets weaker as you go further away. So if you want to maximize the gain in potential energy you get from your teleportation machine, you want to use it as close to the planet as possible.

(An easy way to see why this must be true is that an object's potential energy at infinity is finite, so each additional interval of distance must decrease in energy in order for the sum of all of them to stay finite.)

Teleporting an object 1 meter up gives it more energy the closer it is to the planet, because gravity gets weaker the further away it is. If you're at infinity, it adds 0 energy to move further away.

I think your error is in not putting real axes on your phase space diagram. If going to the right increases your potential energy, and the center has 0 potential energy, then being to the left of the origin means you have negative potential energy? This is not how orbits work; a real orbit would never leave the top right quadrant of the phase space since neither quantity can be negative.

You also simply assume that arrows of the same length are imparting the same amount of energy, but don't check; in reality, if you want the constant-energy contours to be a circle, the axes can't be linear. (Since if they were linear, an object that has half its energy as potential and half as kinetic would be at [0.5, 0.5], which is inside the unit circle.)

(I'm assuming that when you say "momentum" you mean kinetic energy, but those are different things. You claim that any point on the Y axis has equal momentum and energy, but setting aside the fact that these quantities use different units, momentum is proportional to speed, while kinetic energy scales quadratically.)

Why is it a sickness of soul to abuse an animal that's been legally defined as a "pet", but not to define an identical animal that has not been given this arbitrary label?
