@xarene Gross. What happened to you is way worse!
@1NickRoss This is the first time that I read someone's twitter bio, saw "lawyer," and went "YES!" #thankyou
True story: someone accused me of plagiarism of a sentence that appeared in my book #Treknology. After providing the accuser with sources of where I got my info, I put *his* text through a plagiarism checker. Guess what? 100% match... with Wikipedia.  https://www.facebook.com/permalink.php?story_fbid=10154927352081012&id=14587131011&comment_id=10154927954911012&reply_comment_id=10154928028691012&notif_id=1516329655813573&notif_t=feed_comment 
@DrShepherd2013 @PhysicsToday That writer is @jnamatt and he is a remarkable individual. You two should connect!
@robinhanson @ntaylor963 Remember how long it took Voyager to "leave the solar system"? That's because the Sun's protection extends a long way! Also, remember that kinetic energy is 1/2 m v^2, so a v that's 20 times as large gets 400 times the energy!
