So, why is it that we aren't travelling to the stars now?
Why was project orion shelved, its a perfectly viable method of space travel yet why with all our modern technology cant we build the dam thing and explore this galaxy? Where does the future of the human race lead if we stay stagnant on this insignificant little blue rock?

to quote xkcd:
The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision.

so /sci/, WHY must humanity be like this. WHY.tiff

How many people on /sci/ are /fit/?

James is playing a card game called sum game. He holds 8 cards,numbered 1 to 8.Each time he places a card on the table he finds the sum of all the cards he has placed on the tables so far.To win the game, alternate sums must be dividable by two different numbers.For example, if he plays the cards in order 5,1,4,2,8,7,3,6, the sums are 5,6,10,12,20,27,30,36 which are alternately divisible by 5 and 3, starting with 5.

James has cards numbered 1 to n.He places them so that the alternate sums are divisible by positive integers a and b, starting with a. Show that, if the card numbered 1 is placed in an even position, the maximum value for a+b is 2n+1.

I can't do this. Can anybody help explain?
