55 Great Sites For Woodworkers :Construction Management Schools: Construction Management Degree Do you have a love for woodworking? Having a husband that loves working in the garage and two sons in woodshop at school, I decided to put this list of sites together to help them as well as help others. From the novice to the advanced, if you are looking for some tips and tricks, design ideas, or just want to see what others are doing, this list has what you are looking for. These sites are not listed in any order other than by general topic. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. – Chris Baylor is the woodworking guide for About.com. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 48. 49. 50. 51. 52. 53. 54. 55.
100 Very Cool Facts About The Human Body – Global One TV: Multimedia for Mystics 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. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. The largest internal organ is the small intestine. Bodily Functions We may not always like to talk about them, but everyone has to deal with bodily functions on a daily basis. Sneezes regularly exceed 100 mph. Sex and Reproduction As taboo as it may be in some places, sex is an important part of human life as a facet of relationships and the means to reproduce. Senses
The flea's knees (and every other part of its anatomy): Stunning close-ups of see-through water insects By Daniel Miller Published: 13:57 GMT, 4 May 2013 | Updated: 15:52 GMT, 4 May 2013 These stunning images may look like extras from a sci-fi movie - but they are actually close up images of water fleas and other tiny creatures. Photographer and marine biologist Daniel Stoupin takes incredibly close-up photographs of the miniscule marine creatures - so they become almost completely transparent. His photos show everything from sea plants to water fleas and mosquitoes, all of which are photographed so closely that they are barely recognisable. A water flea known as a Polyphemus seen in extreme close-up in one of photographer Daniel Stoupin's incredible images of the tiny marine creatures Biting back: A close-up of mosquito's head appears as some alien creature from a sci-fi movie Creepy customer: A close up of a mosquito showing its hairy body and swollen thorax 'I have always loved animals, especially invertebrates, especially smaller ones.

How to Build a Marble Machine The centerpiece for this marble machine are the gears. They lift dozens of marbles at a time and send them down an amazing track of twists and turns. At first glance I thought this creation was some sort of wooden gear clock. The only thing that gave it away was the fact there were no hands on the face, not to mention it was missing numbers. If you go to the project site (click on the image) you will find an array of chutes and barrels and other things for the balls to do on their way down. It inspires me to think about designing a clock that has a marble run aspect. I have seen some marble machines that are built to tell the time. I counted the Ball Bearings in the gears.
10 places where anyone can learn to code Teens, tweens and kids are often referred to as “digital natives.” Having grown up with the Internet, smartphones and tablets, they’re often extraordinarily adept at interacting with digital technology. But Mitch Resnick, who spoke at TEDxBeaconStreet, is skeptical of this descriptor. Mitch Resnick: Let's teach kids to code Fluency, Resnick proposes in this TED Talk, comes not through interacting with new technologies, but through creating them. The point isn’t to create a generation of programmers, Resnick argues. In his talk, Resnick describes Scratch, the programming software that he and a research group at MIT Media Lab developed to allow people to easily create and share their own interactive games and animations. At Codecademy, you can take lessons on writing simple commands in JavaScript, HTML and CSS, Python and Ruby. While we’re at it: bonus!
Binaural Beats Choose a Binaural Beat to suit your mood from the below. Note that in order for Binaural Beats to work, they must be played though headphones. Basic Beats Deep Meditation Hangover Helper Roommate Annihilator Self Hypnosis Sleepy Time Super Focus! WARNING: DO NOT listen to Binaural Beats while driving, operating equipment, or any other task that requires concentration. How It Works When two tones of specific frequencies are played through headphones, the brain can become confused and produce its own, imagined tone—a three-dimensional audio hallucination heard only within the head of the listener. What is happening is that the brain is not used to hearing frequencies in each ear so close together and with such intensity—these sounds do not occur in nature and so a mechanism in our brains has not evolved to understand them. Binaural Beats were discovered in 1839 by Prussian physicist Heinrich Wilhelm Dove (1803 – 1879) but they didn’t gain much public interest until the early 1970s.
I want sparks & I want them NOW! Update May 2003 - Marx Three is now up & running Do you like the idea of tesla coils and other high-voltage sparking stuff, but don't have the time, money or patience to build something that elaborate? Here's a fun little project that can make big, fat, noisy sparks at least 2 inches long, and can be built very quickly and cheaply. The Marx generator consists of an array of resistors, capacitors and spark gaps arranged as follows: The capacitors, C, are charged up in parallel via the 1M (one megohm) resistors, so they each become charged to the input voltage. Rb has a ballasting effect. Although it is possible to make a Marx generator with just an array of resistors, capacitors and spark gaps, it can be hard to make it fire reliably, as it will depend on the breakdown voltage of the spark gaps, and there can be a fine line between not firing and firing before all the capacitors are fully charged. Component choice An input voltage of about 4-8KV is recommended. Power supply "Marx Two"
8 shocking things we learned from Stephen Hawking's book 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. For example, if all we know is that a particle traveled from point A to point B, then it is not true that the particle took a definite path and we just don't know what it is. Yeah, we're still trying to wrap our brains around this. The authors sum up: "No matter how thorough our observation of the present, the (unobserved) past, like the future, is indefinite and exists only as a spectrum of possibilities." 2. This fun fact: A 1-watt night-light emits a billion billion photons each second. Photons are the little packets that light comes in. 3. 4. 5.
