/sci/ - Science & Math

sup /sci/.
I was reading a bit about evolutionary biology and animal behaviour today, and On the part about sexual selection i noticed it always seems to be the females doing the choosing, and the males competing, in each species. I was just wondering why that is, and i have some ideas about it myself, but i want to see what you come up with.
for example, with peacocks, it is the plain looking peahens that are choosing mates with very bright attractive plumage, and the males are competing for female attention.
even with humans, ive noticed men seem to be fairly slaggy and not too picky about which women they get, they seem to make do with anyone (or maybe thats just the men i know) and its the women being choosey. although that could be partly because of pressures from society, where for a man to sleep with lots of women, he seems to get a lot of respect for it from some people, but for a women to sleep with a lot of men she loses respect, and is a 'whore'/'slut' etc.
the whole 'master key' vs 'shitty lock' scenario.
anyway, i'm rambing as usual.
tl;dr: thoughts on sexual selection, /sci/?

well honesty is always the best policy, and i can see why you don't want to offend him...so you can tactfully start up a light discussion about it if you wish, maybe starting with "I think the subject of religion is important, and i don't believe in god, and i don't want to offend you, but..."
or, live and let live works out as well. next time he starts spouting about god, just calmly but firmly tell him that you don't believe in god, arn't interested in hearing about god, and you will just drop the subject untill evidence comes in.

...you're like the sixth person who wants to go out for coffee....does /sci/ just love coffee?
secondly, i don't plan to meet up with anyone over the internet.
thirdly, if you reply so disrespectfully to me, why would i want to meet up with you anyway?

maybe.. i'll have a shot. post the problem.

yeh, watch it. its a good channel.

i get 28.
5! + 2X(3!) + 1 = 15 + 2X6 + 1 = 28

hey.

look at the right side of the triangle, from points A to C we move 10, yes? and thats the closest distance between A and C. another route, A-O-C we move X+X+4, so 2X+4> 10, so 2X>6, so X>3

furthermore X<4 because otherwise the line BO would leave the triangle, as it would be 10 units long

so we know 3<X<4

hope this helps.. ive no idea how to work out exactly what X is tho..
