Six. How Quantum Suicide Works". A man sits down before a gun, which is pointed at his head. This is no ordinary gun; it's rigged to a machine that measures the spin of a quantum particle. Each time the trigger is pulled, the spin of the quantum particle -- or quark -- is measured. Depending on the measurement, the gun will either fire, or it won't. If the quantum particle is measured as spinning in a clockwise motion, the gun will fire. If the quark is spinning counterclockwise, the gun won't go off.
Nervously, the man takes a breath and pulls the trigger. Go back in time to the beginning of the experiment. But, wait. This thought experiment is called quantum suicide. Hot Ice :) Pearltrees videos. Andolf1986. Researchers now able to stop, restart light. By William J. Cromie Gazette Staff "Two years ago we slowed it down to 38 miles an hour; now we've been able to park it then bring it back up to full speed.
" Lene Hau isn't talking about a used motorbike, but about light – that ethereal, life-sustaining stuff that normally travels 93 million miles from the sun in about eight minutes. Less than five years ago, the speed of light was considered one of the universe's great constants. Albert Einstein theorized that light cannot travel faster than 186,282 miles per second. No one has proved him wrong, but he never said that it couldn't go slower.
Hau, 41, a professor of physics at Harvard, admits that the famous genius would "probably be stunned" at the results of her experiments. "It's nifty to look into the chamber and see a clump of ultracold atoms floating there," Hau says. She and her team continued to tweak their system until they finally brought light to a complete stop. "We didn't have much contact," she notes, "just a few e-mails. " Procrastination. The Misconception: You procrastinate because you are lazy and can’t manage your time well. The Truth: Procrastination is fueled by weakness in the face of impulse and a failure to think about thinking. Netflix reveals something about your own behavior you should have noticed by now, something which keeps getting between you and the things you want to accomplish. If you have Netflix, especially if you stream it to your TV, you tend to gradually accumulate a cache of hundreds of films you think you’ll watch one day.
This is a bigger deal than you think. Take a look at your queue. Psychologists actually know the answer to this question, to why you keep adding movies you will never watch to your growing collection of future rentals, and it is the same reason you believe you will eventually do what’s best for yourself in all the other parts of your life, but rarely do. A study conducted in 1999 by Read, Loewenstein and Kalyanaraman had people pick three movies out of a selection of 24.
Sources: Placebo Buttons. The Misconception: All buttons placed around you do your bidding. The Truth: Many public buttons are only there to comfort you. You press the doorbell button, you hear the doorbell ring. You press the elevator button, it lights up. You press the button on the vending machine, a soft drink comes rattling down the chute.
Your whole life, you’ve pressed buttons and been rewarded. It’s conditioning at its simplest – just like a rat pressing a lever to get a pellet of food. The thing about buttons, though, is there seems to be some invisible magic taking place between the moment you press them down and when you get the expected result. Maybe there’s a man inside who pulls out the can of soda and puts it in the chute. You just don’t know, and that’s how conditioning works.
The problem here is that some buttons in modern life don’t actually do anything at all. Non-functioning mechanisms like this that motivate you to fool yourself are called placebo buttons, and they’re everywhere. Sources: Hold It Against Me" - Britney Spears (Sam Tsui Cover) How to nap.

(Original source unknown . . . this version expanded and Illuminated by SJ.) Bertrand Russell - to our descendants-Mozilla Firefox. Bananas and Monkeys. Original source unknown. (But the story appears to have some basis in fact.) Start with a cage containing five monkeys. Inside the cage, hang a banana on a string and place a set of stairs under it.
Before long, a monkey will go to the stairs and start to climb towards the banana. As soon as he touches the stairs, spray all of the other monkeys with cold water. After a while, another monkey makes an attempt with the same result - all the other monkeys are sprayed with cold water. Now, put away the cold water. After another attempt and attack, he knows that if he tries to climb the stairs, he will be assaulted. Next, remove another of the original five monkeys and replace it with a new one. Most of the monkeys that are beating him have no idea why they were not permitted to climb the stairs or why they are participating in the beating of the newest monkey.
After replacing all the original monkeys, none of the remaining monkeys have ever been sprayed with cold water. The Experience and Perception of Time. What is ‘the perception of time’? The very expression ‘the perception of time’ invites objection. Insofar as time is something different from events, we do not perceive time as such, but changes or events in time. But, arguably, we do not perceive events only, but also their temporal relations.
So, just as it is natural to say that we perceive spatial distances and other relations between objects (I see the dragonfly as hovering above the surface of the water), it seems natural to talk of perceiving one event following another (the thunderclap as following the flash of lightning), though even here there is a difficulty. Kinds of temporal experience There are a number of what Ernst Pöppel (1978) calls ‘elementary time experiences’, or fundamental aspects of our experience of time. Duration One of the earliest, and most famous, discussions of the nature and experience of time occurs in the autobiographical Confessions of St Augustine.

Many have fallen by the wayside but a number have stuck. This is a list of the top 10 schools of philosophy. 10. Nothing exists; Even if something exists, nothing can be known about it; Even if something could be known about it, knowledge about it can’t be communicated to others. - Gorgias (485-375 BC) Solipsism is the idea that one can only know that one’s self exists and that anything outside the mind, such as the external word, can not be known to exist. Solipsism is often associated with nihilism and materialism. 9. Everything is determined, the beginning as well as the end, by forces over which we have no control. . - Albert Einstein (1879-1955) Determinism is the philosophical theory that every event, including human cognition and behaviour, decision and action, is determined by an unbroken chain of prior occurrences. 8.
