In Your Brain Alright, so how does a guy top the whole "spike in the brain" thing?
Two spikes? How about 12? Back in 2006, a guy in Oregon got really depressed, probably because he realized he lived in Oregon. He decided it was time to end his life and after ruling out faster, better, more proven alternatives, he decided he would end it all by shooting himself in the head with a nailgun (we've all been there, right?). We're going to go out on a limb and assume that he was probably a bit disappointed when the first nail pierced his skull and he found himself still alive and in Oregon. He was serious about ending it all though and kept pulling the trigger on the nail gun like a guy waiting for an elevator.
"Eh, a gun is a gun, right? " He finally went to the hospital and complained to the doctors that he had a headache. The nails had gone so far into his brain that the doctors couldn't even see them until they X-rayed his head. "What the fuck? " Thing in a Jar. Thing in a Jar 7 inches by 4 inches, mason jar Pictured above is the Thing in a Jar that's usually sitting in my office at work. The coolest thing about the Thing is that everyone responds to seeing it by asking questions. Where did I find it? Is it an internal organ? Is it some sort of fetus? The Thing in a Jar is made out of Sculpey, acryllic paint and rubber cement. This is the third Thing in a Jar I've made. Here's a conceptual sketch I made of this Thing before I sculpted it. 1.5 by 2.5 inches, ballpoint pen Usually when I make a Thing in a Jar, I try to keep the shape ambiguous enough so that the viewer cannot really pin down exactly what they're looking at.
The glass jar acts as a physical barrier, preventing the viewer from directly accessing its contents. I think this is much cooler than, for example, a painting, which basically has this big implicit sign hanging off of it that says, "I am just a painting of an object, not the object itself. Update OK here's what you do. That's it! About 23. This is about the synchronicity number 23, and thus about the phenomena of synchronicity in general. To write about this topic objectively is impossible, as all experiences are necessarily subjective, involving as they do the element of consciousness, which cannot be instrumented. This is perhaps a study in the affirmation that any assertion of an objective observer is inherently impossible, and yet at the same time there is a deeply imbedded pattern of coherency in all that we regard as random.
Randomness itself is nothing more than a pattern of deeply imbedded complexity of order; an order so complex it is not immediately discernible or obvious. Indeed the often heard rational defense, "that was just a coincidence," is itself an acknowledgment that we have just discerned a pattern, but because there is no immediately obvious path of mechanistic causation behind it, we are consciously choosing to refuse to acknowledge the primary data. 6521449_700b_v1.jpg (567×5754) 5 Reasons We May Live in a Multiverse. The universe we live in may not be the only one out there.
In fact, our universe could be just one of an infinite number of universes making up a "multiverse. " Though the concept may stretch credulity, there's good physics behind it. And there's not just one way to get to a multiverse — numerous physics theories independently point to such a conclusion. In fact, some experts think the existence of hidden universes is more likely than not. Here are the five most plausible scientific theories suggesting we live in a multiverse: 1. Infinite Universes Scientists can't be sure what the shape of space-time is, but most likely, it's flat (as opposed to spherical or even donut-shape) and stretches out infinitely.
So if you look far enough, you would encounter another version of you — in fact, infinite versions of you. View gallery Space-time may stretch out to infinity. 2. 3.

Tesla: Master of Lightning. "In almost every step of progress in electrical engineering, as well as radio, we can trace the spark of thought back to Nikola Tesla" - Ernst F.
W. Alexanderson Tesla with one of his famous "wireless" lamps. Published on the cover of the Electrical Experimenter in 1919. Few inventors contributed more to advances in science and engineering in the early 20th century than Nikola Tesla. As one of the Fathers of Electricity, Tesla did groundbreaking work on alternating current (AC) power system, electromagnetism, hydroelectric power, radio, and radar to name a few. As fate would have it, Tesla, one of the world's greatest inventors, died penniless and in obscurity. Today, there's quite a bit of resurgence in Tesla's popularity, which is helped in part by his mystique as a "mad scientist. " Tesla Company letterhead. In their book, Tesla: Master of Lightning On a personal note, it has taken me far longer than I expected to write this excerpt for Neatorama Spotlight. An Old World Childhood. 7 Man-Made Substances that Laugh in the Face of Physics. The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive.
But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... #7. Ferrofluids What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant? A ferrofluid is a liquid that reacts to magnetic fields in trippy ways that make you think that science is both magical and potentially evil. Tell us that didn't look like the birth of the most sinister dildo ever. What happens is that when a magnetic field is applied to the fluid, the particles of iron compound inside align to it. What the Hell is it Used For?

From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech.
The book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen in a definite way. Instead they happened in all possible ways. This is related to the probabilistic nature of matter and energy revealed by quantum mechanics: Unless forced to choose a particular state by direct interference from an outside observation, things will hover in a state of uncertainty. Yeah, we're still trying to wrap our brains around this. 2. 3. 4. 5. 6.

The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.The brain operates on the same amount of power as 10-watt light bulb.
The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Hair and Nails Facial hair grows faster than any other hair on the body. Internal Organs Bodily Functions. Sixty Symbols - Physics and Astronomy videos. Quantum gas goes below absolute zero. PHOTOCREO Michal Bednarek/Thinkstock Temperature in a gas can reach below absolute zero thanks to a quirk of quantum physics.
It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery. Lord Kelvin defined the absolute temperature scale in the mid-1800s in such a way that nothing could be colder than absolute zero. Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles. Absolute zero corresponds to the theoretical state in which particles have no energy at all, and higher temperatures correspond to higher average energies.
Schneider and his colleagues reached such sub-absolute-zero temperatures with an ultracold quantum gas made up of potassium atoms. Can hot water freeze faster than cold water? [Physics FAQ] - [Copyright] Written Nov, 1998 by Monwhea Jeng (Momo), Department of Physics, University of California Yes — a general explanation History of the Mpemba Effect More-detailed explanations References Yes — a general explanation Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect. This seems impossible, right? What's wrong with this proof is that it implicitly assumes that the water is characterized solely by a single number — its average temperature.
It is still not known exactly why this happens. Why hasn't modern science answered this seemingly simple question about cooling water? So with the limited number of experiments done, often under very different conditions, none of the proposed mechanisms can be confidently proclaimed as "the" mechanism. Finally, supercooling may be important to the effect. History of the Mpemba Effect Evaporation. How to Extract DNA from Anything Living. First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas.
But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds. The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy Peas Pour your thin pea-cell soup through a strainer into another container (like a measuring cup). Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix. Let the mixture sit for 5-10 minutes. Pour the mixture into test tubes or other small glass containers, each about 1/3 full. Why am I adding detergent? Astronomy Picture of the Day Archive. Top 10 Ways Your Brain Is Sabotaging You (and How to Beat It)
@Firesphere: Not that I don't believe you, but do you have a source for that? @inverts: I did, it was an article on a Dutch website. I'm searching for an English source. It was testet with CAT scans etcetera, the male brain showed indeed no activity when asked to "shut your eyes and calm down, think of as less as possible" Where the female brain kept being active. *Searches on* A funny side-fact on this: "Female" gays, seem to never be able to "shutdown" where as "male" lesbians were able to completely stop thinking. Sorry, I am unable to find the article I got this information from.
If I find it again, I'll let it know offcourse. @Firesphere: The article suggests from that information, that those with a "masculine" mindset (for lack of a better term) can shut their brains down; "feminine" brains always have at least one task running then? Why Nikola Tesla was the greatest geek who ever lived. Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too. History.com has a great article about Edison and how his douchebaggery had a chokehold on American cinema.
