I'm adding my vote for sticky too!:)

thanks:)

sorry for being inaccurate. By 3 same figures I mean any number between 100 and 10 000 that contains 3 same figures, one after another (eg. 333,1333...) or in some other order (eg. 414, 52525). And there cannot be more than 3 same figures (eg. 7777), there must be exactly three

Thanks everybody:)

Thanks, I understand that, but I don't understand if they met, why would the twin that remained on Earth been older? Why couldn't it be that all of us that remained on Earth were aging more slowly than the twin in spacecraft ? thanks:)

Hi everybody! :) can anyone help me with this idea: in the twin paradox, a twin that travels at speed of light in space should be younger than the one that remains on earth. But why can it be other way? Can we say that the twin on the Earth is traveling at speed of light compared to the twin in...

Hi! I'm sorry if my question is a bit stupid. How many numbers between 100 and 10000 have exactly 3 same figures? I saw this question on the Internet and I couldn't get the right answer. Somehow I got 657, and the answer should be 333. Can anyone help me? Thanks:)

Can anyone help me with this? The basic equation in quantum mechanics says that E=n*h*v(nu) where n = 1,2,3,... How is then possible that the quantum linear harmonic oscillator has an energy E=(n+1/2)h*v? If someone can explain this, please help
