1. ### Michio Kaku

He taught me last semester. He's the co-founder of string-field theory. I don't know about if he's the HEAD PHYSICST lol... but he's a really...REALLY good speaker. Although if people ask him questions which he thinks are dumb he's gonna single them out lol.
2. ### Interested in looking at the night sky

Hey guys. I wanna get started in looking at the night sky from my roof etc etc. I was thinking of getting Celestron SkyMaster Giant 15x70 Binoculars with a tripod as a starting tool which is only about \$70-80. I don't want to buy a \$4,000 telescope without knowing what I'm looking for lol...
3. ### How would I measure the angle of a certain street from true north?

One more question I gotta ask you guys, I had posted another thread relating to a phenomenon called Manhattanhenge where the sun aligns with the streets in Manhattan twice a year where it gets a nice view during sunset. http://en.wikipedia.org/wiki/Manhattanhenge I've been asking these...
4. ### How would I measure the angle of a certain street from true north?

Ahh ok, cause i've been calculating them manually so far based on the latitudes and longitudes, I hoped google maps had that whole function set up lol. What you guys suggested will definitely save some time though. Thanks!
5. ### How would I measure the angle of a certain street from true north?

I can't seem to find that function. Mind helping me out?
6. ### How would I measure the angle of a certain street from true north?

As the title says, I want to measure the angle of a street from true north so I can know what time of the year the sun will align with it.
7. ### Manhattan Solstice

http://en.wikipedia.org/wiki/Manhattanhenge "Manhattanhenge – sometimes referred to as the Manhattan Solstice – is a semiannual occurrence in which the setting sun aligns with the east–west streets of the main street grid in the borough of Manhattan in New York City. The term is derived from...
8. ### Mendel's genetic experiments

I'm trying to look at specific methods and results in how mendel did his experiment. The number of plants in the P generations, F1 generations etc that show the exact ratio between them. I'm finding it kind of hard to do so though. Can anyone help?
9. ### Electronic properties of graphene

I was reading all over the place that graphene has some really great electronic properties that could potentially replace silicon, electrons in graphene behave almost like massless particles etc. My question is, HOW did scientists find out these properties in graphene? What kind of experiments...
10. ### The side of my rear tire popped!

So there's no way or method I can personally even attempt eh. That sucks >_<
11. ### The side of my rear tire popped!

4000 BC , can you help?
12. ### The side of my rear tire popped!

So I was driving down the road the other day, when I unknowingly drove over a pothole, I was not going even 15mph, and my rear tire popped, I stopped to notice what was wrong, and to my dissatisfaction, the side of the tire had popped. Naturally I'm pissed because apparently theres nothing I can...
13. ### Limits involving trigonometric functions

Limit....does not exist......?
14. ### Limits involving trigonometric functions

Ok so what i did is (2sin5x/x)/((3x-2tan2x)/x) and i separated it into 2 limits so lim 2sin5x/x , then i do 2sin5x/5x * 5/1 then i get for the top fraction 10 x->0 then for the (3x-2tan2x)/x , i did 3x/x - 2tan2x/x , then i did 2tan2x/2x * 2/1 which gave m 4, then obviously i...
15. ### Limits involving trigonometric functions

I'm not following you, you mean times it by 1/x or....times x/x...?
