Physical Computing There are a number of mechanisms common to mechanical systems of all sorts that are useful to know about when you want to control motion of any sort. While this page is by no means comprehensive, it will help get you started on understanding a few basics of how to move things. Before we go much further, there is one important thing you need to know. All of these machines are used to do work of some kind. The Lever The lever is about the simplest of machines, one we're used to deling with every day, from can openers to car jacks and millions of other everyday devices. The ratio of the long arm to the short arm tells us the mechanical advantage of the lever, which is the ratio of work put into the system to work done. The Pulley Pulleys are series of moving wheels and ropes, chains or wires used to gain mechanical advantage. The more pulleys we add, the greater the mechanical advantage we get. These notes are heavily indebted to a number of sources: Flying Pig's mechanics section
All Can Be Lost: The Risk of Putting Our Knowledge in the Hands of Machines - Nicholas Carr We rely on computers to fly our planes, find our cancers, design our buildings, audit our businesses. That's all well and good. But what happens when the computer fails? On the evening of February 12, 2009, a Continental Connection commuter flight made its way through blustery weather between Newark, New Jersey, and Buffalo, New York. The crash, which killed all 49 people on board as well as one person on the ground, should never have happened. The Buffalo crash was not an isolated incident. The first automatic pilot, dubbed a “metal airman” in a 1930 Popular Science article, consisted of two gyroscopes, one mounted horizontally, the other vertically, that were connected to a plane’s controls and powered by a wind-driven generator behind the propeller. And that, many aviation and automation experts have concluded, is a problem. The experience of airlines should give us pause. Doctors use computers to make diagnoses and to perform surgery. Who needs humans, anyway?
How to Build a Solar Heating Panel with Soda Cans If you’ve got good sun exposure on one side of your house, you can take advantage of free heat from the sun with this DIY solar heating panel, which uses old soda cans to collect and transfer the sun’s energy into your house. Sometimes, low-tech solar devices are much better than high-tech ones for home use, as they not only tend to be cheaper to make, but will also last much longer before any repairs or maintenance are necessary. And even better, they can be built in part from repurposed or recycled components, which is something you don’t see very often in new solar devices. This solar space heater design uses old soda cans to increase the surface area for heat transfer inside of it, and in its most basic design, uses no external power to move the air. Double-glazed glass or polycarbonate panels make up the front of the device, allowing the sun’s rays to enter it while restricting heat loss to the outside air, and the box is also insulated for more efficiency.

Idaho Observer: How to remove mercury and other heavy metals from your body – safely and inexpensively From the September 2007 Idaho Observer: How to remove mercury and other heavy metals from your body – safely and inexpensively Due to the enormity of the problem of heavy metal poisoning in today’s world, and the fact that entire books have been written on this subject, this column will attempt to bring to light some of the methods people have successfully employed to regain their health without going bankrupt in the process. By Ingri Cassel In the July, 2007, Back to Basics column we covered the devastating effects of mercury poisoning and the fact that many Americans experience the effects of mercury being slowly released on a daily basis from dental fillings. Simply removing them is NOT a safe method. This is undoubtedly the most expensive part of detoxing from mercury—removing the source that is in your mouth. To check for the presence of heavy metals, many people still go by hair analysis. Chemistry professor Dr. Dr. Dr. The following is from Dr. Dr. www.autism.com www.toxicmetals.info
Magic mushrooms expand your mind and amplify your brain’s dreaming areas – here’s how Psychedelic drugs alter consciousness in a profound and novel way that increases the breadth and fluency of cognition. However, until recently, we were unable to offer an explanation for how the brain was altered to account for these effects. In a new study, published in Human Brain Mapping, we scanned the brains of volunteers who had been injected with psilocybin – the chemical found in magic mushrooms which gives a psychedelic experience – and a control group who hadn’t, and discovered two key things: that psilocybin increased the amplitude (or “volume”) of activity in regions of the brain that are reliably activated during dream sleep and form part of the brain’s ancient emotion system; and that psychedelics facilitate a state of “expanded” consciousness – meaning that the breath of associations made by the brain and the ease by which they are visited is enhanced under the drugs. Ego and emotion This finding of a similar pattern to dream activity is intriguing. Building a picture
How to Use Potassium Permanganate in Water Treatment Potassium permanganate is an oxidant, but a poor disinfectant. It's often used in well water to control odor and taste, remove manganese, iron and color from the water, and to control biological growth that is considered a "nuisance," such as the Asiatic clam, according to the Environmental Protection Agency. The substance is most often used as a pre-treatment before water is filtered, and is better at removing sulfide odors from water than chlorine. Determine the water's temperature, pH, and manganese and iron levels with a water sample test. Purchase pre-made tablets of potassium permanganate if you do not want to do your own calculations. Filter drinking water to remove the manganese dioxide as well as the elemental sulfur precipitate that resulted from the treatment with the potassium permanganate. Store your potassium permanganate in a cool, dry area, advises the Carus Corporation.
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?

How to avoid getting trapped in FEMA camps By James Smith I wrote a news story recently called “How technology will send you to hell in the FEMA camps” It was wildly popular and raised the question in my mind, “How do I prevent my family from going to the camps?” The first thing is to know what to expect before hand. While people think about the dollar dropping to nothing, or an Obama re-election, you need to consider the most pressing signs of a pending martial law. How pending? About 15 minutes or less away from being put into a bus. Now there are people who would look forward to 3 hots and a cot. But we aren’t those people. So what do we look for? Using the backbone of a military operation, you must make the enemy (that would be you) deaf, dumb, and blind. What does that mean? Deaf means that you won’t know what is going on. Dumb, or mute, means you won’t be able to call anyone, tweet, post a Facebook update, send an email of warning. Your neighborhood is now deaf, dumb, and blind. You need to buy yourself some time.
11 Natural Cheats For Getting Rid Of Cellulite Once & For All Cellulite – sub-dermal fat stores which give skin a signature ‘cottage cheese’ or ‘orange peel’ texture that makes women cringe and reach for jeans instead of shorts – is usually due to a number of factors.

It’s a fact that if you aren’t giving it enough water to work with, your body won’t be able to effectively break down cellulite. Not sure how much water you need? 2. Once you’ve got your water intake down, try dry brushing to eliminate cellulite. – Always brush toward the heart. 3. 4.
