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...?
16. ### Limits involving trigonometric functions

Homework Statement 1) lim sin^2(3x)/x^2 x->0 2) lim 2sin5x/(3x-2tan2x) x->0 Homework Equations lim sinx/x = 1 x->0 lim tanx/x = 1 x->0 The Attempt at a Solution We just began working with limits, and we haven't covered much of trig functions at all, but our prof gave us...
17. ### Speed of light coincidence?

Alright guys here's the challenge. Take this seriously because I don't understand how he got the speed of light, so is someone capable of explaining this thing step by step? My friend is a muslim, an excellent student and he claims that the speed of light is predicted in the Quran. Now he's...
18. ### Need Help with Research Paper

Hey guys, sorry if I put this in the wrong section. Basically here's the thing, I have to do a research paper for my English class, and it is to be science related. That's all fine and dandy, but the thing is, the prof. said that the topic should have two sides to it, basically an argument to...
19. ### Eternal life

Hello guys, I've been thinking about a concept, and to some of you, it may seem like slightly different version of reincarnation, but take it as you may because I'm an atheist and I don't believe in afterlife, and this may sound contradictory to what I'm about to say.. Bare in mind that the...
20. ### Hey everyone

Thanks for the quick response, yea I read on numerous occasions that it's best to major in physics instead because it can leave much more doors open. I'm a very dedicated person; at least to the things that interest me. And no i'm not in it for the money lol.. but it would be nice to have some...
21. ### Hey everyone

So this is the deal, I'm 17, and I have a passion for science, especially Astrophysics, and I want to major in that department, but the thing is, a lot of people that I know tell me Astrophysics is way too hard, it's not stable, you need to be a genius to make something out of it, not enough...
22. ### Hey everyone.

Oh, I feared I put it in the wrong section lol. Thanks for the heads up. I put it there, someone should delete this.

24. ### How Does One Prove One Exists?

I just don't really agree with it. I know what you're saying, but in the softer form of solipsism, I'm conscious and you're a zombie right? So wouldn't you think the same thing? Which one is which. Also, in the solipsism of the hard kind, if i understand correctly, if everything is an illusion...
25. ### So , we don't know how universe began?

Well, there is the Big Bang Theory, but it's a theory, and I don't know a lot about it, so we don't have solid proof as to how(or why?) the universe was created.
26. ### Sun has a twin!

True, there are a lot of factors to be considered, really all humanity can do is wait to advance in technology good enough to take us to other solar systems. For now we can only guess.
27. ### How Does One Prove One Exists?

What i'm trying to say is, if someone might be illusional ( like you are suggesting) then how do I know you're not fake and how do you know i'm not fake. Doesn't add up. If a living thing is illusional, then so is nature, the earth and pretty much the whole universe.
28. ### Sun has a twin!

Interesting article. However, if the sun is 1 billion years older than ours, that would suggest that if there is life on that solar system, it would be far superior to ours. So, how come they have not reached us yet. If we our sun is so identical, wouldn't they have picked up the similarities as...
29. ### How Does One Prove One Exists?

Try killing them, then spend the rest of your life in prison and lets see how much of an illusion that is. Sorry but I disagree with what you just said about the people around you being an illusion. That just adds more unnecessary questions and we would be going in circles.
