Wikipedia: Critical Thinking Critical thinking is a type of clear, reasoned thinking. According to Beyer (1995) Critical thinking means making clear, reasoned judgements. While in the process of critical thinking, ideas should be reasoned and well thought out/judged.[1] The National Council for Excellence in Critical Thinking defines critical thinking as the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.'[2] Etymology[edit] In the term critical thinking, the word critical, (Grk. κριτικός = kritikos = "critic") derives from the word critic, and identifies the intellectual capacity and the means "of judging", "of judgement", "for judging", and of being "able to discern".[3] Definitions[edit] According to the field of inquiry [weasel words], critical thinking is defined as: Skills[edit] In sum:
Scientists extract images directly from brain ::: Pink Tentacle Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. For now, the system is only able to reproduce simple black-and-white images. "These results are a breakthrough in terms of understanding brain activity," says Dr.
Spacewalk - the blue sky below us Blue BathSTS-116 Mission Specialists Robert L. Curbeam, Jr. (left) and Christer Fuglesang participate in the first of the mission’s three planned sessions of extravehicular activity as construction resumes on the International Space Station.

Facts: Extra-vehicular activity (EVA) is work done by an astronaut away from the Earth, and outside of a spacecraft. Hint: Use “J” and “K” keys to navigate from picture to picture. Hello!

Propaganda Techniques Propaganda designers have been putting messages into television commercials, news programs, magazine ads, and other things we read and see for years. These messages have been carefully designed to influence our opinions, emotions, attitudes and behavior. Their purpose is to persuade us to believe in something or to do something that we would not normally believe or do. These messages have been designed to benefit someone, and that someone may not be you! It's not as easy as you might think to spot hidden messages. Propaganda designers know you are on your guard. Nothing says that you can't appreciate a good piece of propaganda, and still agree with the messages hidden within it. Is everything we see and hear propaganda? To protect yourself against the techniques of propaganda, three good questions to ask yourself are: Who does this benefit?
Your Age on Other Worlds Want to melt those years away? Travel to an outer planet! <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your birthdate below in the space indicated. The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. The earth is in motion. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year. We all learn in grade school that the planets move at differing rates around the sun. Why the huge differences in periods? Johannes Kepler Tycho Brahe Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe. Here you see a planet in a very elliptical orbit. Kepler's third law is the one that interests us the most. Let's just solve for the period by taking the square root of both sides: The Gravity Of The Situation Isaac Newton ©2000 Ron Hipschman
