  1. Woah, That is nice to know.
  2. Um...WOW...most explosive topic ihve had so far...Yeah, i learned all the laws in chemistry this year, so i thought i would put it in the chem section. Oh and yes, after a little research i did found out that a physicist named James Clerk Maxwell found Cavendish's paper and found that he had indeed found most of the gas laws before the people they were named after. So i guess that is proof. However i couldn't find anything on why he was such an introvert...so i think it was just something of his childhood or anytime in his past. Also did you know that he was the first to find the mass
  3. Wait I do not get why one can't wrap his head around infinity. Isn't it simply the idea or concept of always, continuously increasing our numbers endlessly. I know that is a terrible definition giving the fact that when you take theinfinte set of all real numbers...you know what happens... It is possible with our number system, especially with the study of prime numbers, we can see that our current number system is capable of this concept, it just cannot be used to assign "olafs". As in, we cannot figure out what level of infinity our certain set is. What is their not to believe about infi
  4. Is it true that Cavendish did indeed discover most of the gas laws before the the people they are named after? And also why was he such an introvert? first topic in the chemistry section.
  5. Well most of your question can be answered if you just think of how evolution works. As an environment puts pressure on the individuals of a species, certain difference in phenotypes allow certain individuals to have a greater probability of surviving and thus allowing them to reproduce more successfully, allowing that positive special phenotype-that allows them to survive better- to reoccur more often in its offspring, thus eventually bringing out a change in the species. But for this process to happen there has to be a pressure on a species to survive, allowing special phenotype to e
  6. Yeah, i am reading a couple books and i believe the one called,"a really short history of nearly everything" is the one that confused me. It talks about GR and SR, but then it also talks about how the Big Bang expanded with just the right amount of gravitational force so that the universe wouldn't collapse in a short amount of time or continually expand faster than it does now, making matter so spread apart that interactions would be very rare and limited. Bill Bryson(the author) also states that Maybe our universe expanded with the slightest extra gravitational force above the perfect needed
  7. Oh sorry, i kind of said,"space at a given moment in time" because i couldn't figure out how to show the relation between space and time in newtonian physics, so i just quoted from Carroll's SR lecture notes. He was trying to explain the difference of how space and time was integrated in a coordinate system in newtonian physics versus that of SR. Carroll seemed to reason that newton did say there was uniform time, but the only way time was tied in with space 3-d coordinates was that: at this moment of time, this is how a certain space was. do you get what i mean? It is hard to explain so just
  8. So, in einstein's theory, gravity is simply a geometric distortion between dimension. So if it so not a force, then howcome there are still theories about the force expanding the universe vs the force of gravity pulling it back one day? Do these theories just ignore relativity?
  9. The reason why Einstein deemed time as not absolute is because according to the laws of physics, time is always constant no matter what. This did not make sense with Newtonian physics, since in Newtonian physics considers space as relative and time as a separate phenomena. Also Newtonian physics relates space and time through the phrase,"space at a given moment in time" So in simple words, newtonian physics goes with your dad's line of thought. However what einstein reasoned was that if space is not absolute, yet the speed of light is always constant then time has to be factor that changes. He
  10. Oh no, we have gone much past linear algebra, we are doing limits and derivatives, so i am learning the basics of calculus in my pre-calculus class, We have also gone over vectors so that should help. But in Carroll's notes it talks about rotating the axis, and taking their primes, that is some deep calculus i have not learnt yet, those things are going to be the things that trouble me.
  11. Yes, Thank you for the suggestions so far, but if anyone has anymore suggestions, please tell me. I have already started reading Carroll's lecture notes, but the math of course requires a good knowledge of calculus, so far right now i am doing a pre-calculus course at high school. So far I am halfway though the 1st set of lecture notes without any big confusions due to math, but if i do start getting confused because of the calculus ill find a more dumbed down version or just learn the calculus itself. Thanks a lot though.
  12. No it cannot, since if you multiply [latex](y-3)x(1+y)[/latex] it would be: [latex]y^2x-2xy-3x[/latex] If you wanted to factor it would be [latex]y^2-x(2y+3)[/latex] OR [latex]y(y-2x)-3x[/latex] but that would be pretty much the end of it. In my eyes at least, it may be wrong
  13. What you could do is have an extremely, extremely, extremely, extremely dense ball or sphere of matter, as dense as the massive black hole that exist at the center of our galaxy. If we could orbit that sphere, Hawking says that a black hole that massive would be able to "slow" time by half for the people orbiting this dense black hole. So five years for the orbiters would be 10 for people on the earth. So i do not know if that answers your question, However it is possible that we could use something of great mass as a time travel machine, since the people orbiting could come back with e
  14. So hey guys, i am planning on sitting down and understanding all the equations that are of or relating to the theory of relativity. I know of some, but do you guys have an order that is best to study them in, especially if I am partially confident that i understand the theory of relativity, but i just want to know the math behind it. Thank You,
  15. Hey that is a good question, ill give you the jist and reasoning behind wormholes, since i am noob too, i don't mind people pointing out my mistakes. Say you take a living creature that lives in the 2-dimensional world and you place him on any 2-d layer on a sphere. Now, as a side note, know that a sphere is 3-d and it is made of an infinite amount of layers of 2-d surfaces. Say you put the 2-d creature on the the outermost layer of the sphere. Also know that creature is living in that 2 dimensional outer surface of the sphere, not over it since the 2nd dimension does not include height.
