  1. Ok, so we are given that {an} is the sequence 1/2, 1/3, 2/3, 1/4, 2/4, 3/4, 1/5, 2/5, 3/5, 4/5, 1/6, 2/6, .... Now, the problem says suppose that 0< a < b <1. Let N(n; a,b) be the number of integers j<n such that aj is in [a,b]. I can't figure out exactly what this means ( i.e. given any n, a, b what does it equal?) It does say that "Thus N(2; 1/3, 2/3) = 2, and N(4; 1/3, 2/3) = 3." Our actual job is to prove that lim n->infinity of [N(n; a,b)]/[n] = b-a. So, I can't begin to start the problem until I figure out what the question even means! Also, if the
  2. Not according to religious beliefs. The statement that we are playing God by creating life from scratch is misleading. We would in fact not be creating life from scratch. This is because God is said to have created life from nothing. Technically we would be using God's creation to create life--not our own.
  3. Lol, I think you should try reading the article... or at least the title of the article. Thanks for the link though. SkepticLance: Even when going to Mars you need to bring starter materials. On Venus you could use inflatable habitats and of course bring the necessary amount of food, water, etc. to start with. After that though, you can get all the major organic materials from the atmosphere. There is a lot of sulfuric acid and carbon dioxide in the atmosphere. Using the solar energy from the sun and also from the reflected light off the clouds you could power both the habitat and the
  4. No way they could set up a habitat on the surface, but that doesn't mean they couldn't establish a habitat on Venus. Check out this article on colonizing Venus.
  5. Hi, it has been a very long time since I last posted on this forum but I recently thought of an idea and thought this would be the best place to pitch it and see what everyone thinks. I got my inspiration from reading about Vacutrains. I was trying to think of ways to improve on it or to make it faster when it dawned on me that there is one place where you never have to worry about evacuating the environment and that was space. I then got a funny picture in my head of a giant track that went from Earth's orbit to the moon. Obviously that wouldn't work but it lead me to another idea. What i
  6. Just search on the internet... your bound to find a few old tests (google is great ). Now, if anyone can answer my question.. what percentage do you approximately need to get a 5 on the AP chem test? (sorry about the thread hijack).
  7. That's what I thought... the lab is not making sense at all. Thanks for the links though, maybe I can argue it a little with my chemistry teacher :\. Would Ka be twice the H+ concentration though?
  8. We have an unkown acid (we think its acetic) and a rough idea of the procedure goes like so... dissolve acid into 50ml of water, take 25ml and then titrate until the indicator turns pink... then add the rest of the 25 ml (untitrated) to the titrated acid. then take the pH of the new solution. Anyways, according to our lab, pKa is supposed to equal pH. I cannot figure out at all why pKa = pH. That would mean Ka = H+. One of our questions is to answer why pH = pKa and I don't think it should. If anyone has any idea I would appreciate it very much. (haven't posted in awhile... been really bus
  9. Manufactured Diamonds A small company, Apollo Diamond, is making larger, industrialized diamonds and might be able to produce them in quantity and with quality. The article talks about the limitless ideas that could come from the diamonds that were never attempted before because of its rarity... and of course De Beers is complaining.

  11. I think he's right, this blinking thing is getting out of control. It could lead to much worse things like an increased number of sniffles or even worse... throat clearings!
  12. Yeah its in PPM, Evangelists take samples of the air and find the heathen to believer ratio. And the greater the homosexuality index the worse weather feels , kinda like with humidity and how it feels hotter.
