In order to sharpen our reasoning skills, we must have a good grasp of our own cognitive biases, as well as the basic laws of the universe.

35 Scientific Concepts That Will Help You Understand The World, by Aimee Groth

But in a dynamic world, new laws are constantly emerging. The editors over at asked some of the most influential thinkers in the world — including neuroscientists, physicists and mathematicians — what they believe are the most important scientific concepts of the modern era. Gates Puts Feynman Lectures Online.

MicrosoftThe new Tuva Web site features annotated videos of Richard Feynman’s physics lectures.

Gates Puts Feynman Lectures Online

Microsoft Chairman Bill Gates believes that if he had been able to watch physicist Richard Feynman lecture on physics in 1964 his life might have played out differently. Mr. Gates, of course, is legendary as a Harvard University dropout who went on to create the world’s most successful software firm. He has told associates that if had watched the lectures earlier in his life he might have become a physicist instead of a software entrepreneur. However, Mr. Tongue controller for the paralyzed offers greater independence. 25 Documentaries Everybody Should Watch. Sans Soleil This is not your average documentary.

25 Documentaries Everybody Should Watch

It is a fleeting memory, a sudden remembrance of times long past, a meditation on time and culture, a touch of an emotional diary. We follow the eyes of a world traveller who makes sharp observations and tries to convey them to his friend. We never learn who they are and where they came from, and this is perhaps a subtle point the documentary wants to make. The narrator’s voice switches from Japanese to German to English to French, thereby embodying the language of the places visited.

See What Happens When a Squid Listens to Cypress Hill

Fascinated by the fast color-changing nature of the squid’s skin and their ability to quickly control pigmented cells called chromatophores, the folks at Backyard Brains wondered what exactly would happen if they played music to a squid. Scientists engineer suicide bomber bacteria to kill other bacteria. In a lab in Singapore, scientists are designing and breeding suicide bombers.

If their efforts pan out, they will be applauded rather than jailed, for their targets are neither humans nor buildings. They’re bacteria. Nazanin Saeidi and Choon Kit Wong have found a new way of killing Pseudomonas aeruginosa, an opportunistic species that thrives wherever humans are weak. It commonly infects hospital patients whose immune systems have taken a hit. The Effects of Marijuana on Consciousness. From: Altered States of Consciousness, edited by Charles T.

The Effects of Marijuana on Consciousness

Tart, Doubleday & Co., 1972, Chapter 22 A marijuana high usually lasts two or three hours, during which a wide range of effects may occur, varying both in intensity and quality. The usual, most noticeable effect is intensification of sensation and increased clarity of perception. : Hacking into the Human. Untitled. Learn to Pick Locks for Fun and an Increased Understanding of Security. New Model of the Universe Says Past Crystallizes out of the Future.

What’s the difference between the past and the future?

New Model of the Universe Says Past Crystallizes out of the Future

Not a great deal, if you take a purely relativistic view of the universe, say George Ellis from the University of Cape Town in South Africa and Tony Rothman from Princeton University in New Jersey. The standard spacetime diagrams used in relativity accord no special status to the past, the present or the future. That’s because they assume that everything evolves from time-reversible local physics. In fact, it is possible represent such a universe using a kind of spacetime diagram in which space and time merge into a single entity. “The universe just is: a fixed spacetime block,”say Ellis and Rothman. This kind of “block universe” has indeed been studied by various physicists in recent decades with limited impact. Today, Ellis and Rothman introduce a significant new type of block universe. What’s interesting is that the transition between these states takes place largely in the present.

Ever wondered how to forecast the weather without actually using instruments? Check the Clouds: Clouds can tell us a lot about the weather. For example, they can tell us if it’s going to be warmer on a particular night by simply being there. That’s because they prevent heat radiation from escaping. They can also tell you whether there will be rain and whether there will be bad weather in general (when you see clouds moving in opposite directions of each other). Check the Humidity: ScienceWorld.

A team from Yale University has discovered a fungus deep in the South American rainforest that can live entirely on plastic - offering hope for new methods of waste disposal.

Plastic-eating fungus could help deal with landfill

Pestalotiopsis microspora, found in the jungles of Ecuador, can digest polyurethane - which often currently ends up in landfill and takes generations to decay. Burning polyurethane releases toxins as well as carbon dioxide; and, while it can be recycled, it frequently isn't. The fungus can live entirely on polyurethane. Fracture Putty can heal a broken bone in days. Broken bones can mean weeks of having to wear a cast and the muscle atrophy that comes with that.

More severe breaks can take months to mend, result in restricted movement, or in the worst cases the possible loss of a limb. Scirus - for scientific information. Psilocybin, the Drug in 'Magic Mushrooms,' Lifts Mood and Increases Compassion Over the Long Term. The psychedelic drug in magic mushrooms may have lasting medical and spiritual benefits, according to new research from Johns Hopkins School of Medicine. The mushroom-derived hallucinogen, called psilocybin, is known to trigger transformative spiritual states, but at high doses it can also result in “bad trips” marked by terror and panic. The trick is to get the dose just right, which the Johns Hopkins researchers report having accomplished. In their study, the Hopkins scientists were able to reliably induce transcendental experiences in volunteers, which offered long-lasting psychological growth and helped people find peace in their lives — without the negative effects.
