### Re: Alien Mathematics: A Math System Beyond our Comprehension?

Just for fun, I'll mention this idea. Sometimes when you perform the math problem, it comes out exactly how you want it to. Other times, it doesn't, despite using the same formula. The only difference in whether it comes out right or not, whether the math succeeds or fails... is whether you think a...

### Re: Alien Mathematics: A Math System Beyond our Comprehension?

Way I see it, if you are writing about aliens with a mathematical system incomprehensible to humans, you have about 4 options. 1) Their system of mathematics can be completely different from ours, with different axioms as well as rules of inference, possibly with few or no real-world applications or...

### Re: Guess the Pattern

Patterns I'm finding: I'm guessing this has something to do with primes, because all outputs are primes, which is further supported by your accidental inclusion of 11 before taking it back. All odd numbers either map to 2 or nothing. All even numbers either map to 3, 5, or 7 in the given sequenc...

### Re: Induction Question

For n=0 the case is trivial: 2=2^(0+1) Assuming the statement is true for n: We have that 2+2^1+2^2+...+2^(n-1)+2^n=2^(n+1). We also know that 2^(n+1)+2^(n+1)=2^(n+1)*2=2^(n+2). Substituting 2+2^1+2^2+...+2^(n-1)+2^n for 2^(n+1) since they are equal: We have 2+2^1+2^2+...+2^(n-1)+2^n+2^(n+1)=2^(n+2)...

### Re: Yes.

A computer talked only in binary.

A human walked up kind of confused.

He asked, "Does 1 mean yes?"

The computer answered: 1

### Re: Infinite Balls and Jugs

Suppose I have infinitely many balls, each labelled with a different specification for a Turing machine(of which there are countably many) so that I have all the Turing Machines ordered in some easily specifiable way. I set the value N to 1 and turn my attention toward the first TM. At 10 minutes, ...

### Re: Two secrets

Therefore with p questions we can reduce the number of possibilities by a factor of at least 2/p. It is possible for one of your subsets to contain just one of his secrets and for him to still reply "false". He can choose which secret to reply with. It is therefore possible that all of yo...

### Re: Two secrets

I don't know yet what the optimal solution is, but one comment I have is that if you are only trying to prevent me from having a subset of 2 with at least one being a solution, then I can find both secrets, because you will never reply 'yes' to any subset of 2 unless it has both secrets in it.

If the puzzle is true to the source material, then it doesn't matter who decides the questions because no one has to answer them truthfully.

My solution: Pirate E gets all 100 coins if alone. However pirate D only needsvhis own vote to survive against E so he will keep all the coins if he is the oldest alive. Pirate C must therefore pay E 1 coin in order to get his vote if C is the oldest alive. Pirate B must pay D 1 coin to get his vote...

Cooperate with the other people in order to get a tie. They have no reason to go back on their word(if you can communicate)

Unless I am exceptional in some way in this puzzle I cannot force a win unless everyone can win.

Who decides the questions and do the answers have to be truthful?

Floor 1065 contains a halting oracle. If you are really lucky. What someone from an extremely lucky Everett branch doesn't know is that it is really just a quantum random number generator.
