I am very interested in learning mysteries of nature and find all the underlying cause. I wish to learn technologies so as to make my study of nature easier and effective.

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.

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?

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 $ct-vt$?

Sorry angular momentum is conserved...
