  1. Now, most of them are [acr=Direct Input Officer]DIO's[/acr](formerly [acr=Direct Input Limited Duty Officers]DILDOs[/acr]) although several of them do have degrees in physics.
  2. Two of your three links are broken.
  3. I must have missed that one. The last one I saw had no link.
  4. That's the one we do. Like I said above. Naval Nuclear Power Training Command. It's the worlds most prestigious nuclear power training program(or something like that).
  5. Define correct.
  6. [acr=Zero Point Energy]ZPE!!!!!!!!![/acr]
  7. ...you clever cookie... Now that you mention it...
  8. I'm confused. Before, you sounded like you wanted a pro-string book. But, you're reading Not Even Wrong?
  9. Which book? IIRC, a few of the most popular are The Elegant Universe and The Fabric of The Cosmos both by Brian Greene.
  10. So, it's no different than the rectilinear motion I learned about in my high school physics class?
  11. Most mutations are benign. IIRC, the mutation rate for humans is somewhere in the ballpark of 20 mutations/generation. Watch Chapter 6 of this. Actually, I recommend watching the entire thing.
  12. Could I get a simple example of how a mechanics problem is solved without the concept of force?
  13. Actually, pounds is an acceptable unit for force and mass. One must just specify which kind. For some reason, people don't like using slugs, so the imperial system came up with a conversion factor (gc=32(lbf sec2)/(lbm ft) don't quote me on the units, though) to mess up all of the equations so we can use lbf instead of lbm. On earth(at sea level), 1lbm weighs 1lbf. For example: [math]F_g=G\frac{mM}{{g_c}r^2}[/math] instead of [math]F_g=G\frac{mM}{r^2}[/math] and [math]KE=\frac{m|v|^2}{2g_c}[/math] instead of [math]KE=\frac{m|v|^2}{2}[/math] That's a good bet since it's not really used anymore. My Physics instructor at NNTPC didn't even know what a slug is.
  14. That's just the first answer I came up with. There may be others. I just trial&errored for a few minutes and that just happened to be the first one I reached.
  15. Don't be so sure. Answer: [hide]x=-3[/hide] Explanation: [hide]Using x as a variable: (3+3)/3-3x3=29 Parenthesis (6)/3-3x3=29 Exponents(N/A) Multiplication(and Division from left to right) (6)/3-3x3=29 becomes 2-9x=29 Now, we solve for x. Getting all terms containing the x variable to one side via addition and subtraction yields -9x=27. Dividing both sides by the coefficient of x yields x=-3.[/hide]
  16. Following standard hierarchy, 6*5*3-3/3=6*5*3-(3/3) NOT (6*5*3-3)/3 It's standard order of operations. Just like you learned in school.
  17. I'm not getting five. Order of Operations(Please Excuse My Dear Aunt Sally). Parenthesis (3+3)x3-3/3=29 becomes 6x3-3/3=29 Exponents There are no exponents, so we move to the next step. Multiplication 6x3-3/3=29 becomes 18x-3/3=29 Division 18x-3/3=29 becomes 18x-1=29 Addition 18x-1=29 becomes 18x=30 Now, solve for x. 18x=30 becomes x=18/30 Reduce your answer. x=18/30 becomes x=3/5
  18. Given: t1=0.69s t2=2.37s g=9.81m/s2 [math]h=\frac{(h+0.5g{t_1}^2)t_2}{t_1}[/math] Multiply both sides by t1 and distribute the t2. [math]ht_1=ht_2+0.5g{{t_1}^2}t_2[/math] Get all your terms with the h variable to one side. [math]ht_1-ht_2=0.5g{{t_1}^2}t_2[/math] Factor out h. [math](t_1-t_2)h=0.5g{{t_1}^2}t_2[/math] Divide both sides by the coefficient of h. [math]h=\frac{0.5g{{t_1}^2}t_2}{t_1-t_2}[/math] Now, you just have to plug in your given values.
  19. [hide]Queue[/hide]
  20. How do we do physics without forces?
  21. ydoaPs

    forces

    Isn't all of science just a description of what actually happens?
  22. Trojan has been around long before they started the Evolve campaign.
  23. I saw a programme on the History Channel yesterday featuring a cheap efficient solar panel no thicker than a piece of plastic wrap. They said they are working on making it even to where you can spray it on. I don't remember who makes the thin rolls of solar panels, but I do think it's still in the testing stages.
  24. Last time I was in DC, I took a photo of a big pile of garbage in front of the EPA.
  25. Trojan has recently started a campaign trying to change America's world view in regards to sexuality. Below is their "beliefs".
