Motion Mountain - The Contents of the Free Physics Textbook for Download All volumes of the free physics textbook are written to entertain pupils, students, teachers and everybody who is curious about the world of motion. The first five volumes present established physics. In contrast, the sixth volume is, as the title explains, a research text. Read the volumes online, without download, here. More details on volume I, on mechanics and thermodynamics, are given here. More details on volume II, on relativity, are given here. More details on volume III, on electromagnetism and the brain, are given here. More details on volume IV, on quantum physics, are given here. More details on volume V, on biology, technology and astrophysics, are given here. More details on volume VI, the strand model, are given here. uh
Potatoes What are we doing in the garden right now? A whole lot of stuff, but let's consider the humble potato. We only grow fingerling types for Manresa. They are tastier and more useful for the chef. I buy my seed potatoes from Ronniger's in Colorado. When the potatoes arrive, I cut up the larger ones (I know they tell you not to, but hear me out here). All the tubers get put in a single layer in seedling trays (open at the bottom for air flow). I like to grow potatoes in 15 gallon pots. First, we disinfect our stash of used pots with a mixture of one part bleach to 10 parts water. We then place only 4 inches of potting soil into the bottom of each pot. Once the soil is in the pots, we simply push five tubers into each one, about two inches under. The pots are then placed in our large unheated hoophouse and watered well. These gorgeous Purple Peruvians were photographed freshly pulled last spring here at the farm.
10 Awesome Online Classes You Can Take For Free Cool, but you need iTunes for nearly everything, and that gets an 'F.' Are there really no other places to get these lessons? I was sure there are some on Academic Earth. Flagged 1. 7 of them are available via YouTube. 2. iTunes is free. 1. 2. Don't worry, we're looking out for you! While I have no personal beef with iTunes, I know that many people share your sentiments — so I actually made a concerted effort to include relevant youtube links when possible.
- StumbleUpon Science News, Articles and Information | Scientific American Can we manufacture matter?" The Latin phrase "creatio ex nihilo" means "creation out of nothing," and it's largely the domain of theology, philosophy and mythology for a reason: the first law of thermodynamics, which is actually a conservation of energy equation. The gist of that equation, as you no doubt remember, is that energy can neither be created nor destroyed. How does this law affect matter? Albert Einstein theorized that matter and energy are interchangeable. Matter takes up space, has mass and composes most of the visible universe around you. When two protons collide in the Large Hadron Collider, they may break apart into subatomic particles called quarks and a mitigating particle force called a gluon. If you were to build a molecule out of atoms, you wouldn't be creating matter. To manufacture matter in a way that adheres to the first law of thermodynamics, you have to convert energy into matter. So yes, humans can manufacture matter.
Make a leaf skeleton Remove leaf tissue to see a beautiful "skeleton" of veins! This project can be done with a variety of fresh leaves in the spring, summer, or fall. (Adult supervision recommended.) Pin It What You Need: Leaves (choose large leaves that are colorful, not dried out)Sodium carbonate (washing soda)Metal potForceps or tweezersPaintbrush What You Do: Measure 4 ¼ teaspoons of sodium carbonate (or weigh out 20 g with a balance) into the pot.Dissolve the sodium carbonate in a half liter (a little more than 2 cups) of water.Heat the mixture on the stove. What Happened: The part of the leaf you can see now is a complex pattern of hollow veins making up the leaf's skeleton.
