How does a blood moon happen?

First of all, the sun appears red during sunrises and sunsets. This is because the atmosphere scatters shorter wavelengths of light, and the more atmosphere sunlight passes through, the redder it gets. At sunrise and sunset, the sun is passing through more of the atmosphere than at noon.

In a lunar eclipse, the earth is between the moon and the sun. In that situation, the earth blocks all direct sunlight. However, the very edges of the earth as viewed from the moon are the locations that are experiencing either sunrise or sunset. So during a lunar eclipse, the moon is illuminated by the simultaneous glow of all the sunrises and sunsets on earth.

This is a summary of college only using two pictures; expensive as hell.

That’s my Sociology “book”. In fact what it is is a piece of paper with codes written on it to allow me to access an electronic version of a book. I was told by my professor that I could not buy any other paperback version, or use another code, so I was left with no option other than buying a piece of paper for over $200. Best part about all this is my professor wrote the books; there’s something hilariously sadistic about that. So I pretty much doled out $200 for a current edition of an online textbook that is no different than an older, paperback edition of the same book for $5; yeah, I checked. My mistake for listening to my professor.

This is why we download. 

Spreading this shit like nutella because goddamn textbooks are so expensive. 

not necessarily art related but as someone who couldn’t afford their textbooks this semester this is a godsend

REBLOGGING because after a little digging, I found my $200 textbook for free in PDF form.

friendly reminder that this exists since I know we’re all going back to college soon

Will reblog every time I see it.
