zep73 Posted October 20, 2018 #1 Share Posted October 20, 2018 This is a thread dedicated to facts that most people didn't know. They are surprising and fun, because when you learn them, you need to think different. And that is one of the goals of science. To educate and make you reconsider what you though was real. Let the fun begin! ------------------------------------------------------------------------------------------------------------------------------------------------------- I'll lead with a thing that everybody has. The cellphone! Fun fact about your phone: When you charge your phone, you don't add electricity to it. The electricity is already in your battery. You just force the electrons back to their origin. So, the energy you provide by charging is used to push electrons in your battery back to their former space. Instead of charge, we could use the words "energy push" to describe what's really happening. 6 Link to comment Share on other sites More sharing options...
zep73 Posted October 21, 2018 Author #2 Share Posted October 21, 2018 (edited) In the night sky, stars are not where you think they are, or what you think they are. Some of them are galaxies. And they are all someplace else right now. What you see is what it looked like millions or billions of year ago.

SHaYap Posted October 21, 2018 #14 Share Posted October 21, 2018 Speaking of blood ... Quote ~ Horseshoe crabs use hemocyanin to carry oxygen through their blood. Because of the copper present in hemocyanin, their blood is blue. ... Amebocytes from the blood of L. polyphemus are used to make Limulus amebocyte lysate (LAL), which is used for the detection of bacterial endotoxins in medical applications.

When it is activated again you get shingles. Link to comment Share on other sites More sharing options...
