Here is the great physicist Richard Feynman explaining the scientific method. He shows how theories are developed and tested. Most importantly, why science is really about knowing what we don't know.

do I do not want to discuss how we would look for new law in general we look for new law by the following Parker price weed SS then we can I don't laugh that's a very true that we compute the consequences of the gas  to see if this is right if it's more that would is right we see what it would reply and then we compare computation results to nicer long as they compared to experiment only Parent Directory with observation to see if it works it's wrong you're not simple statement is the key to science like a different time except or not on scientific to take the gas money people who are not in science think it is Prince I had a conversation about flying saucer some years ago with lady  cuz I'm trying to the gyno about site I said I don't think Flying Saucer Southern antagonist said City it's just very unlikely. so that's the way that is scientific scientific only to say what's more likely and less likely and not to be proving all the time possible impossible timer set for my knowledge of the world that I see around I think that it is much more likely that the report to find what are the results of the known irrational characteristics of celestial intelligence rather than the unknown rational extraterrestrial is it more likely that's a good thing and we always try to get the most likely explanations sitting in the back of the Mind the fact that if it doesn't work then we must discuss the other part was for a while or phenomenon called superconductivity the still is a phenomenal which is that Metals conduct electricity without resistance at low temperatures and it was not a price obvious that this was a consequence of the known laws with these particles but it turns out that it is Huachuca preoperative seen in fact to be the consequence of known laws the explained by this no knowledge of physics it and it is interesting however that that phenomen'eyes not been well established. gotcha we cannot down to you that it's there so if it could be demonstrated extremely interesting to Prince's whether it's right or wrong and many many experiments exist for sure it doesn't work the same classical influences that affect the day that was good to go to the dentist then have that kind of equality it would be wrong the physics theory would be wrong because there's no mechanism by understandable and principal from these things that would make a call that's the reason that the some skepticism among scientists regard to those ideas  Fairfield Court this massive we can definitely would always poop and it definitely wrong look like the consequences Wisconsin calculator that could be a wider range of experiment you compute a wider range of consequences on your wrong laugh like a long time all gravitation consequences for the solar system Anna Cook several hundred years before the slight error of the motion of mercury was developed I've been proved wrong temporarily right but it can never be proved right because tomorrow's it's for I meant May succeed in proving what you thought was right normal we can only be sure we can last so long  some idea with your left alone I must also point out that you cannot prove a theory roll it to make a fully Express metabase and the men how do you figure out the consequences little shut up explain how this works because it can't be proved wrong  skip the process of computing a car what does the definition to look like tell me hates his mother because she didn't correct him I love him and when he was a child multi-window Lone Star buffet. Yo Gotti the results I like not a killer but it's one of the phone  it would be possible to say if it were possible straight ahead of time how much love is not enough and how much longer is overindulgent exactly and then they would be a perfectly legitimate Theory against which you can make sense it is usually said when this is pointed out how much love is info if you psychologically not want to concentrate for now on because I'm a theoretical physicist what goes the how do you make the guesses  Thomas Piccoli as I said before not any important weather gets comes from it's only important that I should agree with experimental should be definite as possible definite possible but you say that is very simple we put machine a great community random Wheeling another word is a dumb man job actually it's quite the opposite and I will try to explain why the first, how to stop they have to be removed so we got a lot of letters from people always getting letters from people who are sick insisting that we go to make holes not guesses make a call to make room for a new gas somebody says you know people always say spaces continuous but how do you know when you get to a small enough to mention that they really are points in between a lot of thoughts separated by the  what I say you know what I was talking to conical amplitude you just told me about that so complicated I'm sorry what what you think those are right everybody was working on this farm and it doesn't do any good to point this out the problem is not what might be wrong but not might be substituted for science of it safest anything besides for example in the case of the continuous pay suppose the precise proposition is that states really consist of a series of dots only in this place turn Banks play something might be wrong but they'll replace it by something and that it's not so easy as soon as it comes almost there secondly definite number of possibilities  I need a bee simple type it something like this working very hard you work for a long time playing open this day and show me Joe comes along who hasn't said anything about what you're doing or anything you know combination 10 20 30  set the time on a thing maybe you already fight 10-20-30 maybe you know that the middle number is I'm not 20 maybe you know that as a matter of fact this is a 5-digit combinations letters don't do any good please don't send me any lettuce time to come off the thing is going to work I don't I read them to make sure Florida.  But I take so long to answer because I usually in the class by 10 20 30
