Sorry that I'm replying to this so late, but the fact that you are doing an experiment and EXPECTING specific results shows that you're a poor scientist. The very POINT of an experiment is to get the result, if you already have a result in your head, why are you doing the experiment?Well, the reason we perform experiments in University is to develope experimental skills rather than to discover the value of a certain constant. The reason why we expect certain results is because we need to learn to identify sources of systematic errors, and the reason we repeat an experiment a lot if we don't get the expected result, is so that we minimize the random error so that we can make sure that the source of error is mainly systematic.
My physics teacher told us this each and every day of class. We are never to enter an experiment with some preformed idea of how it is going to go, because then when we get wildly different results we get confused and do it over and over again, trying to get the 'right' results, which wastes our time and gets us a bad grade for handing in a late lab.
I agree with what your teacher says though, and I never ever ignore any result I get however ridiculous it is compared to what someone else has writen on a book.
That's your problem, your instrument is inaccurate and your sample size is too small, which makes your first statement falseMy sample size was certainly not too small for any experiment. I made sure that the precision was high by repeating the measurements loads of times. lol. And how can you tell that my error came from the inaccuracy of my instruments? Sorry mate but that's a ridiculous statement... it could have been anything.
But hey! this has nothing to do with the topic anymore so I'll ask something that I have been wondering (if someone minds answering):
Does thought and knowledge through time evolve, just like living beings do? or does it develope differently? because if it is the latter, then the future of humans would not depend on the common evolution (or would it?), meaning that the theories of evolution would at best tell us how we have come to be like what we are, but that's about it.... wouldn't it?
