Could u just check my understanding that I have mentioned below. While having a scientific method of studying on microscopic phenomena(atomic theory), at first, scientists make some postulates(assumptions) on atomic theory. Then next, they make hypotheses on the postulates they have made on atomic theory. The hypothesis is like "If these are our assumptions(or postulates) on atom then this will be the possible consequences". After that they test the hypothesis through experiments. If the hypothesis fails the experiment, they will change or modify their postulates to form a better hypothesis. At last if the hypotheses pass the experiment, the hypotheses will be accepted and will be considered as a theory as long as there is no evidence or experiment to conflict or contradict the hypotheses. Is this how a postulate and a hypothesis related to each other in scientific method of studying microscopic phenomena or phenomena beyond reality (like space-time curvature)? Please do reply whether my understanding is right or wrong. Thanks.
Sir, is this correct? The measurements (in S.I. units)of minima of uncertainties position and momentum of a particle of mass 1 nanogram is that their ratio is 1:4. Then what is the minimum uncertainties in the measurement of its kinetic energy? Suppose the uncertainty in position be x, then uncertainty in momentum =4x Then 4x2 = h/4π = 5.3 x 10-35 So x = 3.64 X10-18 So uncertainty in momentum= 4x = 4(3.64 X10-18 )= 14.56 X10-18 Then uncertainty in speed = (uncertainty in momentum )/mass = (14.56 X 〖10〗^(-18))/(1X 〖10〗^(-12) ) = 14.56 X 10-6 Uncertainty in kinetic energy = 1/2 m(∆V)2 = 0.5X 10-12 X (14.56 x 10-6)2 = 1.06 X 10-21J
Hello first thanks about you're explain but I ask if scientists predictions methods can they reach to determination of finding exact speed and position?
This expl seems to imply measurement or poor accuracy of measurement (can't see marble from miles away) is the basis of the principle. I thought nothing to do with measurement but more about the randomness of particle states where in this explanation the states in question are position and momentum.
liking this video is a must.
will do.
Able to understand what is HUP after nine years great job!!!!!!!!!!!!!!!!!!1
Thanks !
Very nice explanation

Brilliant lecture, well explained..
Thanks Michael!
this explanation is very clear, thank you.. but i have one question, i usually use h upon 4 instead of h upon 2... is there any great difference...?
Nicely explained bro...
wonderful explanation...............
Finally it somewhat got into my head
Hey! Thank you :)
good explanation
really very good

Suppose the uncertainty in position be x, then uncertainty in momentum =4x
Then 4x2 = h/4π = 5.3 x 10-35
So x = 3.64 X10-18
So uncertainty in momentum= 4x = 4(3.64 X10-18 )= 14.56 X10-18
Then uncertainty in speed = (uncertainty in momentum )/mass
= (14.56 X 〖10〗^(-18))/(1X 〖10〗^(-12) ) = 14.56 X 10-6
Uncertainty in kinetic energy = 1/2 m(∆V)2
= 0.5X 10-12 X (14.56 x 10-6)2 = 1.06 X 10-21J

fantastic
very good thx !
You should read "parallel worlds" by michio kaku.
h/2.............kindly tell me where the 2 comes from

Actually the smallest particles must have exact speed and position....may be our scientists need another decade for this...
good
aren't there any instruments to see ?
Maybe there is no uncertainty and its more of an illusion of uncertainty and we are looking at well ghost of were it has bin in the past
lol good one ;)
what abiut h/4
Informative yet hard to listen to, too much vaudeville hand motion...
I know they will take another decade or more ..that will be followed by Nobel Prize lol
Thanks!
