  1. Mmmmmmmm.... I am not sure that Mother Teresa is an example anyone wants to follow. But that is another topic.
  2. Return and wash coffee cups (with some small incentive) sounds a great idea. Or maybe the chains could allow customers to use their own plastic travel mugs? A related thing is the over use of wrapping in shops - this I am sure could be reduced with no health issues.
  3. There is no direct link between how hard you work and earnings. If you want money don't apply for a job at NASA - go work for a bank or similar.
  4. My point is that you do see this as a problem. Why? (I don't want to say that it is or is not a problem - only you can decide) It is a question of psychology.
  5. Okay, but one can ask about the wavelength of the light reflected from the cow... and then like just about everything we have to ask 'as measured by who?'
  6. Yes, we tend to call that just mass - other books may call it rest mass. This is true - and the reason for simultaneity of events being a subtle issue.
  7. These two seem at odds... i) You are not trying to get a gf. ii) You see not being able to get a gf as a problem. Anyway, my only advice would be to try to realise that you do have something to offer someone.
  8. Mmmmm .... that does not exactly explian the notion of 'quantum jump'. You have posted a not very well informed and slightly confussed 'round-up' of some aspect of quantum mechanics.
  9. This depends on what they ask!
  10. That sounds a stonger statement that I want to make. The point is that how we measure things depends on the (inertial) frames we use. There is a notion of proper length which is the loosely the 'true' length, this is the length as measured in the rest frame of the object we wish to mesasure. But from other frames the length will be shorter.
  11. Because all mesurements are relative - any choice of intertial frame is as good as another.
  12. This thread is not about me - it is about jobs at NASA and how you (and anyone else) can apply for them. My point is that if you apply, be careful not to claim things that you cannot prove. They simply won't beleive you and you will not stand a chance of getting the job. Answer the questions on the application forms and show evidences.
  13. There is no change... if you have a pair of identical rulers and send one on this round trip, and then compare it with the rule left at home (assuming the rulers are now at rest with respect to each other) then they will be the same length. As Mordred points out the same is true of clocks - they both tick at the same rate when brought back together.
  14. I would imagine that most scientific/engineering jobs at NASA are very well structured and part of ongoing projects. The postdoc fellowships may have more scope. Either way, telling them something and showing them evidence for something are different. If you want people to beleive that you can create scientific questions and answer then then you will need evidence of this - for example a PhD and a thesis that shows this.
  15. https://www.nasa.gov/centers/goddard/jobs.html (jobs at Goddard) https://www.nasa.gov/centers/ames/jobs-internships/index.html (jobs at Ames) https://npp.usra.edu/ (Nasa posdoc program) --------------------------- http://uzay.tubitak.gov.tr/en The 'Turkish Nasa'
  16. It looks like they sent you a standard reply... which is not suprising. I don't know much about jobs as such with NASA, but I know they offer a few postdoc fellowships every year - I looked at one to two in the past but they were never really in my field.
  17. Maybe this is for another thread... but what the heck is quantum jump or leap?
  18. I am not saying that you should publish here, but a search of < 1 second produced The Journal of Mathematical Sociology - IF 0.68 which is okay for a maths journal. http://www.tandfonline.com/loi/gmas20#.V5uZaTXw9YE
  19. Space-time is 'populated' classically by field and quantum mechanically we have particles appearing and disappearing all the time. So yes, the simple idea of a 'true' vacuum is rather an approximation - but one that is good enough for lots of situations.
  20. Quite dark for Helloween... this song as a real deep feel to it.
  21. That is the key point. If all the results of a given paper are already known then a journal is unlikely to publish it - other than as a review paper. Copyright is more an issue for the publishers of journals that the authors.
  22. You really worry about copyright and so on too much... if you have a paper ready then submit it somewhere! I really do suggest you look at the papers you are citing. Generally, a pure maths journal maybe interested in some mathematical problems that come from sociology, but only only if the mathematical problems are interesting and don't require much background information in the social sciences.
  23. As ever... look at the journals that the papers you are citing appear in. Pick a journal from that list - look for journals that publish similar things with a similar level of maths and sociology. My feelings are that as an applied work a journal in sociology maybe best.
  24. I doubt it - not in a very scientific way at least.
