Recently I read about the supercomputer simulation of the 1.3 million atoms of a 10 micron aerosol droplet containing a virus particle and I realized I don't have a good intuitive understanding about how small atoms are or how many make up common items. Take for example, how many ink molecules make up a period on a page with the smallest font size? Or how many photons are being emitted from a typical computer screen pixel, How many pixels make up a single smallest white pixel against a black background? You get the idea.
To continue, my laptop screen is set to the highest resolution, 1366 X 768 is 345mm X 195 mm so apparently each pixel is about 250 um square. Anyone have have any idea how many photons are being emitted per second?
