Brief Answers to Cosmic Questions Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both? Evolution of the Universe Did the Universe expand from a point? More about the Big Bang When they say "the universe is expanding," what exactly is expanding? Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? If you could suddenly freeze time everywhere in the universe, and magically survey all of creation, you would find galaxies extending out far beyond what we can see today. Does the term "universe" refer to space, or to the matter in it, or to both? Today, the situation is reversed. Discovering the properties of space remains one of the deepest and most important problems in modern science.
70 Things Every Computer Geek Should Know. | Arrow Webzine The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. If you’re that type of person and are looking for a few extra skills to pick up, or if you’re a newbie aiming to get a handhold on the honor that is geekhood, read on to find out what skills you need to know. How to become a real computer Geek? 1. 2. 3. 4. 5. 6. 7. 8. 9.
10 great science fiction novels that have been banned @djscruffy: And that's why you're a heathen and should be burned at the stake. @djscruffy: In defense of public schools, I would suggest that the reason many of these books are challenged so often is that they're frequently included in school curriculums and libraries. I grew up in a state that, according to these links, engaged in book-burning less than a decade before my birth. That makes me shudder. But I'm also the child of a public school teacher and am familiar with my mother's and many of her peers' views on children's reading materials. Despite the generally conservative views in my community, my elementary school encouraged me to read A Wrinkle in Time and The Giver and Are You There God, It's Me, Margaret. I suppose I've wandered a bit. @djscruffy: To be fair, it's not usually the schools that want to ban the books, but the few overprotective parents who make wild assumptions about the books we try to teach.

P-III autopsy & Sciency stuff For teaching a course I needed to take a closer look at a CPU. I asked around and got my hands on an old P-III Coppermine that was about to get thrown out. I’ll start with a disclaimer: I know virtually nothing about CPUs, so if I claim something to be true, it probably isn’t. The first challenge is to get the actual silicon processor chip off of the plastic bonding board. In the picture below, the blue thing you see is the back side of the processor chip. Click images for full-size. The blue part in the middle is the actual Si chip. Back side of the circuit board containing the CPU. I figured I should be able to remove the chip by heating it. A saw comes in handy sometimes... Below you can see the result. A piece of the processor chip came off. This is the piece that came off. Now the interesting part begins. This is a piece of the processor. Looking closer, we start seeing some structure inside the holes. Focus is on upper layer. Focus is on middle layer. Focus is on bottom layer.
Professor Loses Weight on Twinkie Diet Mark Haub, professor of human nutrition at Kansas State University, ate a Twinkie every three hours for ten weeks in an attempt to prove that caloric intake, rather than the healthiness of food, was the main factor contributing to weight loss, to which I reply, “Duh.” Halfway through the CNN article on the subject, it is revealed that Haub’s entire diet didn’t consist solely of junk food, but he also took a multivitamin pill, drank a protein shake, and ate some vegetables each day. The consumption patterns, an 1,800-calorie-per-day diet (for a man that should be receiving about 2,600) resulted in Haub dropping his body fat from 33.4 to 24.9 percent in two months. His other health markers improved as well, including his bad cholesterol dropping 20 percent and his good cholesterol rising 20 percent. “When you lose weight, regardless of how you’re doing it — even if it’s with packaged foods, generally you will see these markers improve when weight loss has improved.”

K-MODDL > Tutorials > Reuleaux Triangle If an enormously heavy object has to be moved from one spot to another, it may not be practical to move it on wheels. Instead the object is placed on a flat platform that in turn rests on cylindrical rollers (Figure 1). As the platform is pushed forward, the rollers left behind are picked up and put down in front. An object moved this way over a flat horizontal surface does not bob up and down as it rolls along. The reason is that cylindrical rollers have a circular cross section, and a circle is closed curve "with constant width." What does that mean? Is a circle the only curve with constant width? How to construct a Reuleaux triangle To construct a Reuleaux triangle begin with an equilateral triangle of side s, and then replace each side by a circular arc with the other two original sides as radii (Figure 4). The corners of a Reuleaux triangle are the sharpest possible on a curve with constant width. Here is another really surprising method of constructing curves with constant width:
360 DEGREE SPINNER CAMERA | Panoramic Photography, Photo, Wide Lense Seeing The Big Picture Take your camera for a spin with this topsy-turvy panoramic lens that shoots 360 degrees around its own axis. Snapping out-of-range friends, mountains, city streets - your full surroundings in any landscape - its frame stretches four times longer than your average landscape shot. Inspired by '80s futurism, users hold the camera by its vertical rod and pull (then release) its string to get the lens rolling. In the blink of a shutter, its lens spins once around its base. The result: A breathtaking, wide-angle shot that keeps an eye on the big picture. Produces up to eight panoramic photos on a 36 exposure roll of standard 35mm film.
