in terms of time - im sure everyones come across this question atleast once before...but anyway...
if time can be broken down to something as small as miliseconds and nanoseconds, surley you can just keep breaking it down and down into smaller and smaller measuments, perhaps into infinity - so therefore, by the time ive even "thought" anything, time has already passed....right? so the "present" cant be possible...right?
that's great to hear. you'll make a wonderful teacher. hope you get decently behaved students and not unmannerly, spoiled brats. much success with your new job.
Yes a very good subject. A scientist was given a Nobel prize just a few years ago for users lasers to get down to the Fempto second which is 10^-15. This enabled him to study atoms at the molecular level such as hydrogen.
