Introduction to relativity and 20th century physics

Tesla - Master of Lightning: A Weapon to End War Tesla inherited from his father a deep hatred of war. Throughout his life, he sought a technological way to end warfare. He thought that war could be converted into, "a mere spectacle of machines." In 1931 Tesla announced to reporters at a press conference that he was on the verge of discovering an entirely new source of energy. Asked to explain the nature of the power, he replied, "The idea first came upon me as a tremendous shock... I can only say at this time that it will come from an entirely new and unsuspected source." War clouds were again darkening Europe. The idea generated considerable interest and controversy. By 1937 it was clear that war would soon break out in Europe. What set Tesla's proposal apart from the usual run of fantasy "death rays" was a unique vacuum chamber with one end open to the atmosphere. Of all the countries to receive Tesla's proposal, the greatest interest came from the Soviet Union.

Does studying science make you a better person? Want to be a better person? Spend more time thinking about science. That’s the implication of newly published research, which finds people who study science — or who are even momentarily exposed to the idea of scientific research — are more likely to condemn unethical behavior and more inclined to help others. “Thinking about science leads individuals to endorse more stringent moral norms,” report psychologists Christine Ma-Kellams of Harvard University and Jim Blascovich of the University of California, Santa Barbara. Their research is published in the online journal PLOS One. The researchers describe four experiments, all conducted at UCSB, that back up their surprising conclusion. The first featured 48 undergraduates who read a vignette describing a date rape. After revealing some personal information, including their major, each participant finished the experiment by responding to the question, “How much do you believe in science?”

How to Build a Universe That Doesn't Fall Apart Two Days Later First, before I begin to bore you with the usual sort of things science fiction writers say in speeches, let me bring you official greetings from Disneyland. I consider myself a spokesperson for Disneyland because I live just a few miles from it — and, as if that were not enough, I once had the honour of being interviewed there by Paris TV. For several weeks after the interview, I was really ill and confined to bed. I think it was the whirling teacups that did it. Science fiction writers, I am sorry to say, really do not know anything. It reminds me of a headline that appeared in a California newspaper just before I flew here. Well, I will tell you what interests me, what I consider important. In 1951, when I sold my first story, I had no idea that such fundamental issues could be pursued in the science fiction field. Finally, in the story, the dog begins to imagine that someday the garbagemen will eat the people in the house, as well as stealing their food. What could explain all this?

25 Things You Should Know About Word Choice - StumbleUpon 1. A Series Of Word Choices Here’s why this matters: because both writing and storytelling comprise, at the most basic level, a series of word choices. Words are the building blocks of what we do. 2. Words are like LEGO bricks: the more we add, the more we define the reality of our playset. 3. You know that game — “Oh, you’re cold, colder, colder — oh! 4. Think of it like a different game, perhaps: you’re trying to say as much as possible with as few words as you can muster. 5. Finding the perfect word is as likely as finding a downy-soft unicorn with a pearlescent horn riding a skateboard made from the bones of your many enemies. 6. For every right word, you have an infinity of wrong ones. 7. You might use a word that either oversteps or fails to meet the idea you hope to present. 8. Remember how I said earlier that words are like LEGO, blah blah blah help define reality yadda yadda poop noise? 9. Incorrect word choice means you’re using the wrong damn word. 10. 11. 12. 13. 14.
