Oct 27 awarded Popular Question Jul 2 awarded Curious Dec 22 comment If everything in the universe doubled in size overnight, would it be noticeable? Objects expand on heating. If a circular object with circular hole is heated, both the radius of hole and the object increase. Dec 22 answered If everything in the universe doubled in size overnight, would it be noticeable? Nov 19 asked Could we have assumed the speed of light to be different in different reference frames? Nov 14 revised Find the quantity of charge - given potential function deleted 10 characters in body Nov 9 comment Find the quantity of charge - given potential function Sorry I am not much aware of delta function. Keeping $\delta(\vec r)$ in the result keeps the work of taking Laplacian still intact. So why should I prefer using $\delta(\vec r)$ in my answer of charge density? Nov 9 revised Find the quantity of charge - given potential function Edited a small typo. Nov 9 comment Find the quantity of charge - given potential function Sorry I missed out $\lambda$ in my equation I've now edited that Nov 9 asked Find the quantity of charge - given potential function Oct 31 comment Time dilation $t'=(1-\frac{v}{c})t$ instead of $t'=\frac{1}{\gamma} t$ Thank you for your answer. But, Why wouldn't the observer on the train not agree that the distance between him and the photon is $ct-vt$?
