Like in men in black 2: "Plan needs to be thought out, plan needs to be cool." etc.

Though its perhaps old junk, but what jokes aren't?

Guess you're right. Perhaps I should stop trying to start a conversation on the internet and engage more in discusions at home.

What do you get if you mix fish wine with rise wine?

Dinner wine! Haha!

That's like the first time I've made a real joke. And it wasn't that funny even (given that it was funny at all). And not that complex.

Well, I think of this as one of my most important works.

I think therefor I am the self, is the conclusion that there are requirements of sophisticated thinking in order to be. But surely you don't need to think a certain thing, any thought would do actually. And then we have the argument "doesn't anything fulfill that requirement?", And since we don't need to remember anything to be ourselves, since we don't die if we forget something and we didn't know alot of things before we learned them, I guess that's so. To prove this would be a thing benefitial for all parts. The question is only how to do it... If this wasn't proof enough.

And thank you for your encouraging reply.

Nonono, don't start with neutron stuff. Neuron. wink (Don't take this to seriously)
The process from C to Q is finite. I define Q as the self when all neurons in C has been exchanged.

Clearly the self remains this process, so the D as a function of C remains even though C-->Q

Don't know what the neutrons actually do anyway. But it just because they all look the same to us, doesn't mean they are. Except ofcourse, possibly for an nD solution.

I hope this might help a bit:

(A) 33

(E) it cannot be determined from the information given since you don't know how many that scored 85.

(E) 144 since the combinations is a 3D matrix with length, height and width; 4 ties, 12 shirts, and 3 belts, hence 4*12*3 = 144

ab + bc + ac = c(a+b) + ab = 3

c^3(a+b) + abc^2 = 3c^2

c^3 + c^2*ab/(a+b) = 3c^2/(a+b)

c^2(ab - 3)/(a+b) = c^3

(ab-3)/(a+b) = c


a^3 + b^3 + (ab-3)^3/(a+b)^3 + 6ab(ab-3)/(a+b) is supposedly >= 9

But since a^3 + b^3 and is the lowest when a=b and (ab-3)^3/(a+b)^3 + 6ab(ab-3)/(a+b) is negative for all positive numbers a,b,c hence the whole expresion is possibly minimum when a=b since ab is then max but < 3 since ab + bc + ac = 3 and since -ab/(a+b) is the largest negative when a and b are equal, we get:

2b^3 + (b^2-3)^3/(2b)^3 + 6b^2(b^2-3)/2b >= 9

b^6 + 1/16(b^2-3)^3 + 3b^5(b^2-3) <= 9

But since we also get that since b can be exchanged in this solution to c, c=a=b, and since they are equal when the equation yield minimum, and the only such solution when ab + bc + ac = 3 is when they are all one, we get that minimum is:


2b^3 + b³ + 6b^3 = (2 + 1 + 6)*1^3 = 9

Commerce would help. You could buy cheaply then travel (teleport?) to sell at a profit. Get your calcs wrong and lose money. 500 bricks at 0.43 each, 10% discount for payment in the next 10 seconds!

It makes me think that the game should be seeded with "drones" (AI players) until we get a few hundred real players.

Perhaps you could build an AI that "sells your profit" for you, and then, after enough time, the robot becomes free and becomes a player just like you. Is that somewhat plausible?

Sorry about last post, I missunderstood you.

Teleporting is hard to comprehend. Why not have a person and phone boot at every building? Smoke signals? Arrow messaging?

Exactly! Not just continuing from wherever we were. Actually stop using carbons. Taking vehicle production into concern, that's like the only thing that we can do to stop this from going too far, right?
