Six Famous Thought Experiments, Animated in 60 Seconds Each
by Maria Popova From Ancient Greece to quantum mechanics, or what a Chinese room and a cat have to do with infinity. From the fine folks at the Open University comes 60-Second Adventures in Thought, a fascinating and delightfully animated series exploring six famous thought experiments. The Paradox of the Tortoise and Achilles comes from Ancient Greece and explores motion as an illusion: The Grandfather Paradox grapples with time travel: Chinese Room comes from the work of John Searle, originally published in 1980, and deals with artificial intelligence: Hilbert’s paradox of the Grand Hotel, proposed by German mathematician David Hilbert, tackles the gargantuan issue of infinity: The Twin Paradox, first explained by Paul Langevin in 1911, examines special relativity: Schrödinger’s Cat, devised by Austrian physicist Erwin Schrödinger in 1935, is a quantum mechanics mind-bender: via Open Culture Donating = Loving Bringing you (ad-free) Brain Pickings takes hundreds of hours each month.

Top 10 Moral Dilemmas Miscellaneous Thankfully most of us do not come across dire situations that present a moral dilemma, but it is always a very interesting exercise to consider a dilemma and our reaction to it. So, I now present you with a list of ten agonizing moral dilemmas, in no particular order. (Be sure to tell us what you would do in the comments.) 10. Concentration Camp

5 Mind-Blowing Projects by College Kids College graduates may still have a tough time finding a decent job in this economy, but some students are trying to make the best use of their time in the classroom. We've rounded up five mind-blowing projects by college kids for your viewing enjoyment. Continue reading to see more. Critical Friends: Building a Culture of Collaboration “… a critical friend is someone who is encouraging and supportive, but who also provides honest and often candid feedback that may be uncomfortable or difficult to hear. A critical friend is someone who agrees to speak truthfully, but constructively, about weaknesses, problems, and emotionally charged issues.” — The Glossary of Education Reform Being critical friends means that we can depend on our colleagues to help us reach our potential. We all serve as critical friends (and really, aren’t these two words synonymous?) who push our practice, help one another see bright spots, and offer resources and a clear path for steps to quality teaching and learning.

Sentiment Building to Deport Nation’s Billionaires THE HAMPTONS (The Borowitz Report)—They don’t pay taxes. They circumvent our laws. They get free stuff from the government. They are America’s billionaires, and many would like to see them gone. According to a new survey by the University of Minnesota’s Opinion Research Institute, the American people hold the nation’s billionaires in lower esteem than ever before, and a majority would like to see new laws enacted to deport them. Moral Dilemmas 1. Examples In Book I of Plato's Republic, Cephalus defines ‘justice’ as speaking the truth and paying one's debts. Top 10 Student Inventions You don't have to be a famous researcher or engineer to come up with the next big invention. These ten student projects prove just that. They range from a homemade nuclear reactor to a 300mph electric vehicle.

Teaching Critical Thinking Whether or not you can teach something as subjective as critical thinking has been up for debate, but a fascinating new study shows that it’s actually quite possible. Experiments performed by Stanford's Department of Physics and Graduate School of Education demonstrate that students can be instructed to think more critically. It’s difficult to overstate the importance of critical-thinking skills in modern society.

The Generalized Structure of Moral Dilemmas, The Trolley Problem Among men there are but few who behave according to principles -- which is extremely good, as it can so easily happen that one errs in these principles, and then the resulting disadvantage extends all the further, the more universal the principle and the more resolute the person who has set it before himself.Immanuel Kant, Observations of the Feeling of the Beautiful and Sublime[translated by John T. Goldthwait, University of California Press, 1960, p.74] The most common question I'm asked by such non-legal characters as cross my path, or get talking to me over a glass in Pommery's Wine Bar, is how you can defend a customer when you know he's guilty. Well, the answer is, of course, that you don't. Once the old darling tells you that he did the deed, you've got to advise him to plead guilty, admit all and take the consequences. If he refuses to agree, then you must leave him to his own devices. Another complication is knowledge.

Rare Color Footage of Depression-Era New York In the same year that The Wizard of Oz hurtled Dorothy from a black-and-white Kansas into a Technicolor Oz, Jean Vivier, a French tourist, was filming the streets of New York in all of their own glorious color. A rare 16-mm Kodachrome film from the summer of 1939 that was recently released by the Italian Romano Archives shows swinging signs advertising 5¢ piña coladas, elevated trains whizzing overhead, and boys playing in the fountain of a public park. Archivist Vincente Romano says the clips of Rockefeller Center, Chinatown, and other areas are only a portion of the film Vivier took over the course of his trip from Marseilles to the Big Apple at the close of the Great Depression.

Lucid dreams and metacognition: Awareness of thinking; awareness of dreaming To control one's dreams and to live 'out there' what is impossible in real life -- a truly tempting idea. Some persons -- so-called lucid dreamers -- can do this. Researchers from the Max Planck Institute for Human Development in Berlin and the Max Planck Institute of Psychiatry in Munich have discovered that the brain area which enables self-reflection is larger in lucid dreamers.

Polynomic Theory of Value, Pleasure, Virtues of Franklin and Wooden after Immanuel Kant, Friedrich von Schiller, & Leonard Nelson Miranda There's nothing ill can dwell in such a temple. If the ill spirit have so fair a house, Good things will strive to dwell with't. The Tempest, William Shakespeare, Act 1, Scene 2:459-462 gatewurm » The Abrahadabra Institute superlight and magnetic sculpture gallery by gatewurm Many of these devices were featured in the Transmutational Alchemy show at Olympia Arts Walk, Spring 2012, where they delighted everyone. Gatewurm is the House Director for The Techneion of The Abrahadabra Institute, and an independent researcher and developer of ‘Radiant Energy & Magnetic Energy Technologies’. He has built and designed several energy devices which are powered by, operated by, and even levitated by, magnetic radiant energies. His experimental machines theoretically generate varying degrees of influence over The Body of Light and create some fairly spectacular visual effects. One of his most popular installations is the Eye of Ra levitating coil, a complex copper coil that floats a sphere in the center using computer generated sound waves.
