All Experiments | Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5.
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.

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. 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 The Elegant Universe: Pt 1 The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. BRIAN GREENE: We really may live in a universe with more dimensions than meet the eye. S. BRIAN GREENE:The atmosphere was electric. S.
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. 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. Explore the links on the next page to learn even more about the subatomic world.
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.

Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data Storage Disks Have you ever dream of 100 terabyte of data per 3.5-inch disk? New patented innovation nanotechnology from Michael E. Thomas, president of Colossal Storage Corporation, makes it real. Michael invented and patented the world's first and only concept for non-contact UV photon induced electric field poling of ferroelectric non-linear photonic bandgap crystals, which offers the possibility of controlling and manipulating light within a UV/Deep Blue frequency of 1 nm to 400 nm. It took him 14 years to find a practical conceptualization that would work to advance the storage industry; 3D Volume Holographic Optical Storage Nanotechnology, for which Michael holds the patents. • Join PhysOrg.com on Facebook! This invention and patents on a technique for changing matter at the molecular level is one of the World's only new enabling technologies, having many hundreds of electro-optic applications. “In 1974 I was making 5 Megabyte disk packs - the biggest at that time in the world.
