How to increase serotonin in the human brain without drugs * Randomness as Meaning Introduction This article describes how, in our search for order and purpose in life, people sometimes assign meaning to events that are objectively random and devoid of meaning. Consider these two images — one dot pattern is random, the other isn't: One of the two images above shows a random pattern of dots, the other has been manipulated to resemble a random pattern but isn't really random. In perception studies, most people choose Sample A because Sample B shows tight clusters of dots that don't really seem random. The meaning of this experiment is that, when people see tight clusters of dots (or of events), they conclude it isn't a chance grouping but has special significance. The following sections show examples where, for psychological reasons, people assign meaning to meaningless groupings, significance to insignificant coincidences, even invest in outright frauds based on mistaken perceptions of reality.

Deep Sea Explorers Stumble Upon A Creature They Can Hardly Believe Is Real While there’s no shortage of weird and wacky ideas in science fiction about what creatures from other planets might look like, few are quite as remarkable as those that can actually be found right here on Earth. Recently, a team from the Nautilus Live expedition piloting a remotely operated vehicle (ROV) happened upon one of the most fascinating-looking lifeforms in the world -- this rare, purple siphonophore roving through the ocean’s depths. Even the experienced deep sea explorers, well-acquainted with the marine animals, had a hard time accepting that what they were seeing was really real. “Wow. Okay, that’s awesome,” says one ROV operator. “I can’t believe that’s a living thing.” Amazingly, although this appears to be a single jellyfish-like animal, it is in fact a roving colony made up of thousands of individual organisms, called zooids, each contributing to the whole.

DISCERN Artificial Neural Network - How to Build a Schizophrenic Computer Justin Ruckman/Flickr Advertisement - Continue Reading Below Schizophrenia is one of the most infamous and mysterious mental disorders. Attempting to get to the root of the problem, scientists recently came up with an extraordinary solution: They built a schizophrenic computer. People who suffer from schizophrenia often have difficulty thinking logically or discerning what is real or not real in their lives. To make a schizophrenic computer, they began with an artificial neural network called DISCERN that Miikkulainen has been working on intermittently since the 1990s. Hoffman and his colleagues then started to tell simple stories to the computer. In DISCERN, the process begins in a module called the sentence parser, which examines each sentence one word at a time. Once the computer system could "understand" a story, the researchers began to feed stories to it. Then, it was DISCERN's job to repeat the tales back to the scientists.

The Limits of Intelligence Santiago Ramón y Cajal, the Spanish Nobel-winning biologist who mapped the neural anatomy of insects in the decades before World War I, likened the minute circuitry of their vision-processing neurons to an exquisite pocket watch. He likened that of mammals, by comparison, to a hollow-chested grandfather clock. Indeed, it is humbling to think that a honeybee, with its milligram-size brain, can perform tasks such as navigating mazes and landscapes on a par with mammals. A honeybee may be limited by having comparatively few neurons, but it surely seems to squeeze everything it can out of them. At the other extreme, an elephant, with its five-million-fold larger brain, suffers the inefficiencies of a sprawling Mesopotamian empire.

10 Ways Our Minds Warp Time How time perception is warped by life-threatening situations, eye movements, tiredness, hypnosis, age, the emotions and more… The mind does funny things to our experience of time. Just ask French cave expert Michel Siffre. In 1962 Siffre went to live in a cave that was completely isolated from mechanical clocks and natural light. When he tried to measure out two minutes by counting up to 120 at one-second intervals, it took him 5 minutes. But you don’t have to hide out in a cave for a couple of months to warp time, it happens to us all the time. 1. People often report that time seems to slow down in life-threatening situations, like skydiving. But are we really processing more information in these seconds when time seems to stretch? To test this, Stetson et al. (2007) had people staring at a special chronometer while free-falling 50 metres into a net. 2. We’ve all experienced the fact that time seems to fly when we’re having fun. 3. 4. 5. 6. 7. 8. 9. 10. Time is relative

How Making Robots Captivates Kids' Imaginations Violet: I think school would be a lot more engaging if we were asked to solve complex problems. Building a robot and seeing it run and seeing it complete tasks is definitely more satisfying than any schoolwork I've ever done. Getting an A on the test, that's cool, but seeing something I have built with my own hands move is way more satisfying. So I'll try connecting a one-ten-nine. Man: Yeah, just don't overlap them, right? Woodie: I think a reasonable way to think about robotics is birthing a machine that can be over there and do something that you either taught it to do, or that you're commanding it to do now. Violet: So do you guys know how to test a motor with a battery? Girl: Not really. Violet: Okay, here. So I grew up in a really geeky family. Kjersti: You could do it like that, or you could do it to the top here, so that way the hub would be on the outside. It was something completely new for me. We use rectangular tubing here, along with your average drawer slides. Kjersti: Yes. All:

Stuff no one told you: Simple truths of life At some point in 2010, Alex Noriega, illustrator from Barcelana, was going through a crisis due to some isues at work. He decided to start a blog as a way of trying to find what he was doing wrong. He wanted to put on paper all that he had learned in life as simple as possible and try to see if what was happening around him made any sense. Still, his work is great and we are happy to present it to you! Bethany Hamilton - Surfs Like A Girl by Aaron Lieber Risks and challenges High performance sports films undoubtedly carry several risks and challenges. 1. COST Most quality films in any genre are considerably expensive to shoot, and high performance sports films are certainly no exception to the rule. Camera Gear: To obtain the best footage we will be shooting almost exclusively on RED cameras (with some GoPro), utilizing a range of camera techniques that will include hand held, classic tripod, dollies and finally a drone camera for our stunning aerial footage. Travel: Travel for Bethany, her assistant and our film crew can add up fast. Music: A hidden cost most people are unaware of. 2. Although we are confident we will get all the footage we need for this incredible project - the truth is that some things are out of our control and we must adjust our plans accordingly incurring more costs and possible delays. 3. Learn about accountability on Kickstarter

Short Documentary about Solar Roadways The basic building block of what has been dubbed by its creators, electrical engineer Scott Brusaw and his wife Julie, a solar roadway. It could one day make for a highway built of 0.4 –square-meter hexagonal panels, a hodge podge of green circuit boards surrounding 36-watts worth of blue solar panels, all covered in thick, bumpy glass for safety and traction. The idea is to put unused roadway to good use (generating electricity) while also providing an electronic means for lane shifts, driver messages and other utilities. Bonus: solar roadways obviate the need for an electric grid by including a “Cable Corridor” right in the side of the roadway that eliminates the need for power lines running alongside it.
