the theoretical scientists are just backfilling, developing the theories to explain the activities of & results obtained by the former group? Do we need the theoreticians of science? And if we do or don't, can you explain( giving the reasons) why we do or don't. Please.

side note: This is a Q in the *philosophy of science but it is posted in the *physics category which is most fundamental and comprehensive of all the sciences where more smart and knowledgeable people can be found to answer the Q.

i'm a junior in high school... my brother says it's going to be more difficult to become a pediatrician than a pharmacist... because to become a pediatrician, it takes years and years of studying.. also, how's physics? since i'm taking my other hard classes (pre-cal, chemistry, AP U.S., chinese 5-6, english 5-6 honors), i would like to know if taking physics is better or anatomy...

Long ago, Ptolemy had a theory of the cosmos with an accurate, yet incorrect, mathematical model for it. His version made assumptions that were inconceivable, because they were impossible. I have been told that quantum theory makes assumptions that seem ridiculous, but they must be true because the mathematical model is so incredibly accurate. What are these assumptions? Also, how do we know that it isn't the case that quantum theory is accurate, yet incorrect as the Ptolemic universe was?

Electromagnetic waves are transverse; there are no transverse waves in a fluid; therefore, if there is an ether, it has to be a solid. Q.E.D!

If this is not my own original idea, please point me to a source who beat me to it.

For a project at school we have to drop an egg from 5 meters to the ground without breaking it. There can be nothing attached to it so we have to buld or come up with some kind of platform for it to land on. The platform can't be more than one meter in any direction and the height (thickness) from the ground can not be more than 5 cm (approx. 2 in.) to get an A. So the higher it is above 5 cm. the more points are deducted. Any suggestions? thanks
