An observer (O) is located 400 feet from a building (B). The observer notices a kite (K) flying at a 29° angle of elevation from his line of sight. How high is the kite flying over the building? You must show all work and calculations to receive full credit.

What exactly drives animals (not humans) to have sex? Do females feel pleasure or do they only do it since the males forces himself upon her? What exactly drives the males to have sex? Is there a chemical?

How comes in most animals the female just sits down bored while the male humps her? Didn't females evolve to enjoy sex?

Also do male animals do it foe pleasure or do they do it just for reproduction

Homo Heidelbergensis proved hominids could survive cold climates without just adapting, and homo erectus proved hominids wanted to go places. Homo sapiens migrated from Alaska to Monte Verde Chile between 14,000 and 20,000 years ago.

"No they didn't" ~ the guy who doesn't like walking places because it's too cold

I bet that the heterozygous carriers of Ashkenazi diseases have increased IQ. some groups are 11x more likely to be scientists than normal ashkenazim, some have an average iq of 121 new Mensa level for this group would be 150 whereas in the regular population it's only 132 how can I start a study on precocious ashkenazim i bet they have the most valuable mutations of all

Not the abandoment thereof, but the invention itself.
Intelligent life forms that start off and stay hard materialist would likely remain hedonist/nihilist as civilizations and forego the long-term planning and development required to attain a spacefaring status.

Every number has infinity numbers in between them. Infinity is not a number therefore numbers are not real.

any doctors/healthfags on? My sense of touch feels like it might be reduced. Started when I smoked cannabis couple months back. Now when I smoke the desensitisation feels definitely noticeable and it lingers for days. I don't know if I'm imagining it. I'm a massive hypochondriac. I haven't heard of this being a side effect of weed. Any advice?

I have a theory that it's an extension of weed fucking with my short term memory, like I forget where my hands are positioned or what they were feeling moments ago, so when I think about my hands I'm surprised by the touch senses its experiencing.

I've noticed two types of sound systems that you can come across at a club, rave or live show environment - the second being much more pleasing to experience but at the same time less common.

1) Normie System

> Loud volume levels
> Sound can feel unbalanced i.e. very full bass / too much high end
> Variably tactile experience of sound i.e. feeling bass in body etc
> Commonly experience ear fatigue after some period of time (have to take occasional breaks from music floor etc)
> Difficult to hear and talk to people
> Can't stand near speakers for very long at all
> ^ doing so can quite easily lead to temporary tinnitus for next day or so

2) "Make Me Horny" System

> Volume seems overall like it has the same loudness capability as a Normie System
> More balanced sound - can hear a full range of frequencies and pick out individual instruments / tracks quite easily. Feels like the music can breathe more
> Consistant and enjoyable tactile experience of sound i.e. feeling bass through body; possibly even feeling air movement from speakers etc
> No ear fatigue whatsoever
> Can hear and converse with people perfectly
> ^ This is true even when I'm close to the speakers, which doesn't seem to put the same excessive pressure on my ears
> Tinnitus is not something I have to worry about

If I remember correctly, one of the rigs that falls into the latter category that I did managed to identify is the widely praised Funktion One system..

What's going on here /sci/? It interests me because it kind of breaks everyday wisdom (mostly imparted us by worried parents / aunts / deaf grannies) that louder music is going to kill our ears or give us STDs or something equally as terrible. I'm not denying that volume levels are something that should be taken seriously, but I guess I kind of want to know what the story behind the story is, if you get what i mean? A bit like how all calories aren't made equally and things of that nature.

Hey /sci/ I don't know where else to turn so bare with me for a second. I have no idea what kind of thread this is going to be.

I've always considered myself to be an educated individual and maybe just a bit more intellgient than the average Joe. I read and study daily, I do well in univesity and receive good marks, but there is one subject which I could never get into: Math.

I attended a really shitty Catholic grade school that focused more on teaching us about Religious values instead of making sure we knew how to actually do things like Algebra. By the time I transfered out and attended a public school system I was completely blindsided by the level of math I found myself at. Keep in mind this is basic Algebra at this point. In a way, I fell through the cracks and was left behind. But that's gonna change now.

I recently bought pic related and am going to read through it once I finish my current book. Any advice you guys can give me? Any math majors out there that can offer me some words of wisdom or other ways I can better my understanding of mathematical principles?

Thanks.
