Fragments of a Working Philosophy

• The Sherlock Holmes Principle

  You will not apply my precept" he said, shaking his head."How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?"
  (The Sign of Four)

• Feynman

  It is very important that we do not all follow the same fashion...It's necessary to increase the amount of variety...and the only way to do this is to implore you few guys to take a risk with your lives that you will not beheard of again, and go off in the wild blue yonder to see if you can figure it out.
  (R.F., Nobel Prize Award Adress)
  (on quantum theory)
  It has not yet become obvious to me that there is no real problem, therefore I suspect that there is no real problem, but I am not shure that there is no real problem.

• Dyson

  Drive your plough and your cart over the bones of the dead.
  (Phys.J. May 2005, Interview about Einstein, Quotation: W.Blake)

• Heraklit

  Hen To Pan (All is One).
  Dogs bark at everyone they do not recognize.
  Nature loves to hide.
  If you do not expect the unexpected, you will not find it;
  for it is hard to be sought out and difficult.

• J.J.Thomson

  ...if you pay a man a salary for doing research, he and you will want to have something to point to at the end of the year to show that the money has not been wasted. In promising work of the highest class, however, results do not come in this regular fashion, in fact years may pass without any tangible results being obtained, and the position of the paid worker would be very embarrassing and he would naturally take to work on a lower, or at any rate a different plane where he could be sure of getting year by year tangible results which would justify his salary. The position is this: You want this kind of research, but, if you pay a man to do it, it will drive him to research of a different kind. The only thing to do is to pay him for doing something else and give him enough leisure to do research for the love of it.

• Tolkien

  The Road goes ever on and on
  Down from the door where it began.
  Now far ahead the Road has gone,
  And I must follow, if I can,
  Pursuing it with eager feet,
  Until it joins some larger way
  Where many paths and errands meet,
  And wither then? I cannot say.
  (Bilbo in "The Fellowship of the Ring")

• Helmut Kohl

  The dogs are barking,
  The caravan walks on.
