I just want AI to destroy everything bro I don't care. Either that or aliens, be my guest.

Just create a corporation that's run by AI.
Corporations have more rights than humans, and are legally classified as human.

For all intents and purposes, a AI run corporation is legally speaking human 2.0

It's called high-frequency trading and markets are addicted to it. Eventually it will destroy the markets, and themselves.

Oh, so it's because time is literally light? So, if a person even slightly moves forwards in the direction of light, and then backwards, they will have travelled to the future, however miniscule it may be.

In a nutshell, time dilation occurs so that events happen simultaneously. If you're moving away from an event at half the speed of light and time doesn't dilate, in your perspective it would appear that the event happened after it actually occurred.

Time dilation keeps all the events on the same page.

>>12579090
Right, but i don't quite understand why. Say, for example, person A is standing completely still, but person B moves forward 100000 miles in 1 second and then back 100000 miles in 1 second. Shouldn't time experienced for Person A still be 2 seconds, even when compared to person B?

You are traveling to the future faster. If you went "faster" than light, you would be "outside" of time. Reaching the speed of light is like an asymptote, a speed that you can only get infinity closer to but never reach. At least with our current understanding.

An intuitive way of understanding why this happens is to imagine a cyclotron moving linearly along its rotation symmetry axis, while also spinning a particle in a closed circle.

As the particle’s speed increases, the magnitude of its momentum vector may increase without bound, however, the magnitude of the velocity vector may not. Spinning the particle causes the momentum components in the rotation plane to dominate the linear axis component, so the momentum vector converges into the rotation plane. At the same time, the velocity vector must point in the same direction as the momentum vector, so it will also converge towards the rotation plane, but because the speed of the particle has a finite bound, the particle must lose some of its linear axis velocity component to gain some rotation plane velocity components.

Sure. Nominal monetary value doesn't scale 1:1 with marginal utility. Maybe losing 2.5$ a month is so negligible that the the 1 to 300.000.000 odds of being filthy rich is worth the while to you. I personally prefer to keep the 2.5$.

Still, the average person will pay more into car insurance that she would have to pay for car damages were she uninsured. Otherwise there would be no profit margin on an insurance business. So the difference is degree, you are losing more money on average with both insurance and lottery; where each person draws the cut-off point is always somewhat arbitrary.

>>12579243
Never claimed something different. It’s a question of many factors. Even in the naive portfolio models it definitely can be.

Not him.
But they don’t do it as a hedge to make money, but as a hedge to ensure liquidity. If you end up without a car, but need one to make money it’s pretty bad, if you can’t afford one. Obviously, if you can easily get a loan in that case it’s something different, but you need to factor it in. In some cases insuring something can be good and in some buying a lottery ticked can be, but it depends.

Car insurance does not have a large negative expected value because most of the money they earn is actually invested to yield around a 2% return. Therefore the profit insurers make is not from taking a % of your premium but from their ROI

Depends on what your risk threshold is.
Everybody has a number of recessive mutations in their genome which could cause disease if they were homozygous.
The thing is, the chance of two genetically distant people having a (disabling) mutation in the same gene is very small.
The reason inbreeding causes problems is because people who are closely related are likely to carry the same recessive alleles.
This means that two closely related people are much more likely to give birth to offspring which carries two copies of the malfunctioning gene, thereby causing the child to be diseased.
You could calculate the risk by calculating the probability that a child will inherit two copies of a bad gene.
You could probably do this by considering a non-related male and female who breed to begin a family.
Then, imagine the children of these parents breed with each other, and also imagine the children breed with more unrelated people. Then imagine the children of the non-incestuous group breed with their cousins, etc.
If you take into account the number of chromosomes, and you understand inheritance, the chance of a child being born homozygous for a bad gene in each generation should be calculable (albeit a pain)

Hollywood decides what movies get made because Hollywood has the money.

It won't make a lick of difference.

>>12579008
When you only need a $1000 gaming PC to make a movie, it won't matter how much money Hollywood has. Every church, social group, middle school, sports club, and even every motivated individual will be able to make their own movies. Most of them will be crap but people with talent will be able to make whatever movie they want without bending a knee to Hollywood and changing everything to be whatever the studio wants.

heres how you would figure it out:
put a magnet out into space directly above your head
with a metal pendulum feel the force acting on the pendulum by the magnet
now:
A) if the earth is a sphere you should be able to find a place on the map where instead of feeling an upwards force you feel the pendulum pull to the side only
B)if the earth is flat you will always feel a partial upwards force on the pendulum no matter where you are as its always above you and never to your side.
alternatively: you could set up a gyroscope which ensures you have always a straight line then go on a trip around the equator until you get back to your original position. would that satisfy you?

For the purposes of that problem, all you care about is the energy associated will bond breaking and forming to calculate some enthalpy of reaction. How it breaks isn't of interest. However, it looks like a catalytic hydrogenation reaction which requires a metal catalyst like Pd to be present. Essentially, the hydrogen breaks and bonds to catalyst metal surface where the molecule is also bound to and then a reaction happens. I attached a picture of a double bond because I couldn't find one for a triple bond but the mechanism is probably similar. Catalysts mechanisms are not generally known in great detail although I think some guy got a Noble prize awhile back for figuring out some metal catalysis stuff.

>>12578625
>>12578636
>>12578688
alright thank you. So it seems that there might be a little more to it than what's written in a highschool chemistry textbook. Seems like how the actually reactions happen is probably not set in stone and there might be some nuance to it depending on the situation. I knew little about catalysts and orbits and those were certainly not part of the explanation in the textbook.

To me it seemed like breaking double, triple or quadruple bonds between two atoms just to reform a smaller bound right after would be a waste of time and nature wouldn't actually allow that, but depending on the orbits and catalysts, I mean, yea maybe.

>>12578773
>To me it seemed like breaking double, triple or quadruple bonds between two atoms just to reform a smaller bound right after would be a waste of time and nature wouldn't actually allow that
It is thermodynamically favorable to form the bonds but if you don't have catalyst you might never see the reaction happen to a great degree (kinetics). The energy of the triple bond molecule and hydrogen is higher than the products of single bond molecule so it is favorable to occur but you have to "get over the hump" (activation energy) so the reaction occurs.

>>12578567
Breaking two pi bonds is ENERGY EQUIVALENT to breaking two pi bonds and a sigma bond and then reforming that sigma bond.

>>12578773
>So it seems that there might be a little more to it than what's written in a highschool chemistry textbook
So it seems like you misunderstand your high school (underage b&) textbook. Enthalpy change only depends on the initial and final states, the path between them does not affect the equilibrium of the reaction. Nobody is making any assumptions about transition states here.

Women who habitually wear makeup look worse without it than they would if they never wore makeup in the first place. Makeup is very bad for skin and ages women who use it rapidly. This of course is good for business as far as the makeup industry is concerned.

The reason men don't wear makeup is because they're smarter than women.
