  1. Here's a better list of units to fight over, I'm still pushing the "Sagan" https://en.wikipedia.org/wiki/List_of_humorous_units_of_measurement
  2. Mimas cause it looks like minmus when written down
  3. Trust me, metric is better than a Pi based numeral system! That definition of a second is same as the imerial one, the SI one is caesium. Imperial is just a bunch of historical references which make conversion between different ones tricky, and again trust me, you don't want your doctor to be fiddling around with unit conversion when giving you say insulin/morphine etc.
  4. http://physics.nist.gov/cuu/Units/second.html as for why caesium, I'm not going to do a physics lesson, but regardless it changes between to energy levels predictably (and it is more constant than doing it by rotation of the earth which does change)
  5. As a physician I am so much more comfortable using metric, just because it is easier to convert between units, you don't want to confuse your 1mol/kg dose with a 1mg/dL! SI is essentially metric, just kelvin instead of celcius (which is just add/subtract 273.15)
  6. as for base 10, it's just a quirk of the number system we use
  7. The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.
  8. Metric is an attempt to make a system based upon "natural" scales, so a gram is a mL of water and fills a 1cm sided cube and takes 1 cal to heat it by 1 degree. The interantional standard for a metre is now based on the speed of light (the distance light will go in 1/299 792 458 of a second)
  9. I always find it weird listening to american news and even science shows where they talk about feet, pounds, farenheit. I was looking at xkcd today and I wondered, would a shift to the metric system make a difference or is it just semantics? (also in the UK we are taught metric in class, but our roads are in miles)
  10. I tried it, four air brakes was less efficient than four large reaction wheels, gonna stick to less realistic physics!
  11. The search function on curse is rubbish though It's irritating that to work around this through google
  12. I think my rtg has a bug cause as soon as I put one on it makes the ship explode as soon as it gets into space, that was back in 1.0.4 days though, I just got used to not having them so...
  13. Also I thought a big advantage of a space elevator was not wasting energy on barging through an atmosphere, so what would be the point on building it on a world without an atmosphere (yes I do know about other energy losses from rocket engines but they are so much easier to build)
  14. They did send probes which is how they knew there were planets beyond
  15. My school uses KSP to teach the third years orbital mechanics as an end of year treat. but then we are the geekiest school in Cmabridge UK (a geeky place indeed) I'm a doctor, Google is more than dangerous, it's incredibly irritating when your rotation puts you onto A&E...
  16. And glow beautifully which is useful when the lights no longer work
  17. Why SSTO when the mission is the best bit! The only time I've used one is as a crew shuttle to get the ill fated King Edward the second (smashed into the space potato after a glitch) manned for the mission
  18. I use it early in career for the test [x] on launchpad, that's about it Oh and I put it on everyship with jeb in it just in case he goes crazy(-er) and has to have mission control assume command!
  19. I found out that the quote function is really hard to remove from an iPad I was launching a Laythe probe, it could fly for about half an hour and the wings were retractable behind it's heat shield. Just as I was aerobreaking around Jool my cat jumps on my keyboard (her name is poppet) hitting space, staging my fairing, the whole probe burns up in a matter of seconds leaving a heat shield now in a degrading orbit of jool try again tomorrow.
  20. Isn't the current plan for a manned mars mission to have the transfer unit built by ESA
  21. My advice is lots of pictures and as few numbers as possible! Even statisticians switch off when a presentation becomes to numbery!
