  1. Is it possible to have it shipped to the U.S.? I checked it out once I heard about the offer, but did not see shipping options for outside of the local area.
  2. Video A great production from BBC. I had not seen this before so I figured I would post it for others that had not seen it. After I watched this, I downloaded the entire show and was very pleased with the quality, both in content and production value. It was refreshing to see quality graphic work put into an evolution video. **I posted this here so as to make it visible to everybody rather than sticking it in biology as it's more light-weight than I would expect for that forum. Feel free (as I know you would) to move it if deemed necessary.
  3. One thing that I notice from a cursory view is that your solutions are written like fractions. I kept wondering why you were ending up with rational expressions until I noticed the pattern.
  4. Thank you for your response. I'll be looking into Sturm's theorem, although it's probably way over my head at this point. I've pretty much just been doing what you mentioned. I just look at a specific term and estimate about what I need to change my divisor to in order to make it positive or negative. I was just wondering if there was something that I missed. I suppose that i'll just have to get used to the idea that not everything is perfectly clear, especially as I progress into more advanced mathematics.
  5. I have a quick question regarding the identification of the lowest upper bound and the greatest lower bound for the zeros of a polynomial function. The method that my book shows is to use to upper and lower bound theorem involving synthetic division. This involves performing division with 1, 2, 3, etc. and -1, -2, -3 etc. until the bounds are found, but what if the lowest upper bound is something like 57 or 89? I'm I supposed to perform division for every number or is there a way to identify a smaller group of possible bounds. I've just been using the results of division to estimate about
  6. I seem to be having an inordinate amount of difficult with understanding the concept of horizontal stretching and compressing graphs. Vertical stretching and compressing makes sense. [math]y=2f(x^2)[/math] If I understand it, this is simply multiplying the output of the function by two. All that happens is that the [math]y[/math] value is double whatever it would be as a result of [math]y=f(x^2)[/math]. This means that an input of 1 gives a [math]y[/math] value of 2, an input of 2 gives 8. This would stretch the graph away from the x-axis due to the y value increasing faster than it otherw
  7. I'm not a physicist (yet) but I would say that being open minded in any scientific field would mean that you do not dismiss theories that you do not agree with without objectively examining the evidence.
  8. It's usually a good idea to keep the question and post the solution once it's found beneath the question. That allows others to view the solution if this thread is found via Google search or the forum's search function. Or was this thread just moved to a different forum? Meh.
  9. Just thought that I would let you know that you are awesome. The quality of your posts are very high (where applicable) and played a very large role in my decision to begin visiting the forum daily. Since I joined a couple of months ago, you, along with some of the other advanced members, have astounded me with your grasp of your fields of study (although I am hardly qualified to rate your expertise) and renewed my outlook on the value of online communities for the discussion of science. I grant you one 'woot', do with it as you please.

    Mildly relevant information: I'm a physics major, which has made you particularly appealing....academically that is...<_<.

  10. Go to a local community college for a remedial math course. This will start from a very basic level and move up to pre-algebra. Don't be afraid to ask questions in class. Aside from that, without having an instructor, you will find any type of auto-didactic methods frustrating.
  11. That was indeed a wonderful talk. Dawkins never fails to deliver.

  13. Religion is attacked because of it's demand to be believed as correct. (Varies with different religions.) A preference of pepperoni over sausage does not mean that the sausage eaters are wrong, it's accepted as an opinion. Many religions on the other hand declare themselves to be true and all others to be false. They may even go as far as to damn those who chose another belief to spend eternity in hell, or reincarnate as a lesser being or object. Now, depending on how far the religion takes this, it can become a burden on others which is evident through war and crime done in the name of any
  14. From the video it looks like he jumped or at least began to jump as the car hit the crates. This would make his movement completely separate from the crates, the only risk would be the possibility of him falling off early and being run over or having a crate hit the windshield and come back up at him. If he had stood on the crates the whole time he would have likely been just fine anyway. I'm not a physicist (yet) but if I had to guess I would say that his inertia (or resistance to a change in his state of motion) would keep him from moving anywhere but down due to gravity. The car would likel
  15. I'm pretty sure my focus with switch to C soon. I program in Python currently as a hobby.
