A 196 is a meme sharing forum with the name 196. I don't really know how to describe a tankie, but something like: a leftist person who glorifies autocracy and the use of force to make a leftist utopia.

How is it possible that roughly 50% of Americans can’t read above a 6th grade level and how are 21% just flat out illiterate?

There are levels of illiteracy. Most everyone has some literacy but the classifications are not very detailed, so completely illiterate may include being able to read a menu and choosing simple items.

Following an instructions manual for assembling/mounting something is much harder. Because of how frowned upon illiteracy is people who are illiterate get good at hiding their illiteracy.

CD / DVD / BD

All three images are from an electron microscope that has captured a section of each type disc. I don't know if they are all zoomed in the same amount but I think it is implied that they are. The black bar tells you how much they are zoomed in by showing you a line that I 1 micrometer long.

Maybe the image of the CD is the background because they want to show us the black bar from that image specifically. Perhaps they were just a bit lazy with the cropping or thought it looked cool that way.

I'm the images I can see that a DVD is a flat surface with lines of 'trenches'. That's probably how they do either a 1 or a 0.

The CD has a much larger pattern and has hills instead of trenches. The size of the pattern is probably what decides how much data you can fit on a disc, smaller is better.

The Blue Ray uses trenches, like DVD, but with a smaller pattern.

I know nothing about the community.

I thought you'd done something wrong at first, but the image shows up when I went into the post itself.

It should not show text as image preview but yeah, I see it too
