WITH NO SURVIVORS

Can we have a math puzzles thread?

Step 1: send 4000 emails touting your lock prediction game for this weekend. half pick home, half pick visitor.
Step 2: throw away the 2000 addresses where you picked the wrong team, then send a mail to the remaining 2000 bragging about your prediction and making a prediction for this weekend, half pick the home team, half pick the visitors.
Step 3: throw away the 1000 addresses who you gave the wrong pick
Step 4: send message to the remaining 1000 addresses bragging about your two predictions, saying that if you want to get any more winners you'll need to buy my $99 pick'em service.

I don't know about Sportsbetting, but unless all betting websites use the same (or one of few) ratings to predict their winners, there got to be sites with bad predictions that are beatable, just because there are so many betting sites.

Velocity does not affect force. An object at rest has no acceleration because all forces acting on it cancel out (gravity going down, normal force going up). Similarly, an object that is going 10 m/s on a frictionless plane has the exact same forces acting on it, and thus the same acceleration (0 m/s/s).

But the mass grabbing on the pulley would decelerate at a rate of 1.5g after grabbing thus exerting more force

Oh, sorry, Clarke was assuming that readers would be self-aware of their own limitations and wouldn't be entitled ignoramuses who think that "all explanations are going to come to me if I wait long enough for other people to do it for me."

>>9153647
Why do you believe it's bullshit? If you were to take a neanderthal out of his time and to our present and showed him a computer, do you think he'd interpret it as anything other than magic?
From there, imagine there's a future human who does the same thing with us and that they're as far beyond us with technology as we are beyond the neanderthals. Doesn't it follow we'd see the amazing things they have in that time as magic too? Granted you could say we'd be able to assume there were some rational explanations behind how these miraculous contraptions, but without knowing anything about how they worked it would probably at least *seem* like magic from our perspective.

The cost savings. Tens of millions.

Well, I don't know about math, but it happened to music. It was all pure and good until Schoenberg came along. Then the Jews came flooding in, claiming that aesthetics is arbitrary and what have you. It's no wonder all popular music is shit.

>We

what papers have you published anon?

>>9153711
A few.

The problem with this kind of thinking is that, hypothetically speaking, if evolution was TRUE, you could still come up with these same complaints. Therefor the argument is worthless trash.

You just set up an imaginary point in the evolution of man and decided that everything before that point is just a mutant monkey and everything after that point is just a mutant human.

a mathematical line has a thiccness of zero

>>9152761
but then wouldn't the space it occupies be zero, contradicting it being a line? its dimension would be zero, but then you say it can map a set, and not just that, but it can fill up spaces and whatever. how is this possible? doesn't that contradict it having a dimension of 0xR?

Alright fine you fucking plebian. There's actual rigorous definitions of how space filling curves work, but you clearly don't know them and I'm not going to spoonfeed you. For your imbecilic, 3-D monkey brain it would suffice for me to just lie to you. So I will. A line doesn't have zero thickness. It's thickness is the smallest positive number greater than zero.
>but that number doesn't exist
You don't even fucking care if it doesn't exist. You can't even prove it doesn't exist because you don't know/care about rigor. You just want to be right and appear smart and curious. You're not curious. If you were you would read. You can learn the magic or you can swallow the bullshit I just fed you. The choice is yours.
