  1. Happy Birthday MadHatter!

  2. Happy Birthday =)

  3. Happy Birthday!

  4. happy brithday :D

  5. Stopping power, Steady Aim and Bando . Man I haven't played this in sooo long!
  6. They're both good weapons, and if you're used to them go for it. The thing is for me is that whenever I use them I can't help feeling I'm not doing as well as I would with the M16 or MP5. And I'd also say the M16 is bettter than the AK47.
  7. Ok, I'll concede thought that when I did use LMG's (ages ago / when I was doing challenges) the RPD was my favourite . Such a good balance of fire power and rate of fire, with little recoil!-
  8. Tut tut . I can't really bring myself to use LMG's anymore, but I'll concede they were fun for a while . SMG's For the win!
  9. The maths of this is explained in my earlier post
  10. Haha nothing is wrong with them, I just don't listen to them very much any more and they don't represent my current music taste. However, I am still fond of them! Thanks Co heed . Righty-ho Mobby, I'll try
  11. I'd say the best rom-com-zom I''ve seen. And yes, I know only like 2 exist but still
  12. • The Usual Suspects • The Truman Show • The Producers • The Butterfly Effect • Pulp Fiction • The Road • The Blues Brothers • Star Wars • Kill Bill 1 & 2 • The Big Lebowski • The Shawshank Redemption • Withnail & I. • Toy Story 3 RocknRolla Lock Stock and 2 Smoking barrels
  13. Hiya Perfectdrug, welcome to our forums
  14. Red shift is definate fact. There is no disputing it's effects. However, as they say, it is not the most reliable method for measuring the distance of a galaxy. You can measure a galaxy's distance away using Hubbles law: v = H*d (V= velocity, H= Hubble's constant and d=distance). Ie You can work out distance as it is proportional by Hubble's constant to a galaxies velocity away from us. You work out the velocity away using the Doppler shift as described above. The wavelength of the radiation emitted, say, from a Hydrogen atom comes in definate quanta. Thus by comparing the new wavelength to the old through this equation: ((W-Wo)/Wo)*C = V (W = new wavelength, Wo = wavelength when not moving as measured on earth, C = speed of light, V = velocity). I would type lamda but I don't have that key on my keyboard . Thus you have the velocity away from us. Note, that Hubble's constant is still disputed today and not truly known. Also, if the galaxy is accelerating or decelerating (possibly due to a collision or so forth) then yes it becomes less accurate. For Cepheid Variable Stars (stars that pulse light), using the stars apparent luminosity, and its absolute luminity, and comparing the two, you can work out the distance away. You do this as from the Period of the pulse, you can work out Absolute Luminosity (M). Apparent Luminosity (m) is simply relative birghtness how it appears and then using d = 10^((5 - M + m)/5) you have the distance in parsecs. This process was discovered by Henrietta Levitt. Also, not that once you have worked out Hubble's constant in the first method by measuring the gradient when plotting Distance versus Velocity, using H = 1/T (T = Age of Universe) you can work out the age of the Universe. Hope this helps. Also, <3 Physics. Source = a course at Cambridge University.
