How big is a mole? (Not the animal, the other one.) - Daniel Dulek A comprehensive biography of Avogadro can be found here: The mole is taught in every introductory chemistry class one can take at the college level. Here's an example of a chemistry course: There is an entire day dedicated to commemorating Avogadro's Number. National Mole Day: 8 Cheat Sheet Wallpapers for Designers and Developers Web designers and developers have a lot to remember, from keyboard shortcuts to function names. That’s why it’s handy to have cheat sheets near by for a quick reference. Most people like to print out there cheat sheets on paper and have them sitting on their desk, but another convenient place for a cheat sheet is right on your computers desktop in the form of a wallpaper. Here we’ve rounded up a few very useful cheat sheets for web designers and developers that can be used as desktop wallpapers.

Copenhagen Interpretation of Quantum Mechanics First published Fri May 3, 2002; substantive revision Thu Jan 24, 2008 As the theory of the atom, quantum mechanics is perhaps the most successful theory in the history of science. It enables physicists, chemists, and technicians to calculate and predict the outcome of a vast number of experiments and to create new and advanced technology based on the insight into the behavior of atomic objects. But it is also a theory that challenges our imagination. It seems to violate some fundamental principles of classical physics, principles that eventually have become a part of western common sense since the rise of the modern worldview in the Renaissance.

Reversible flow (when I show this in class, minds are blown) 12Google + 33StumbleUpon Interesting video showing Laminar Flow and demonstrating fluid flowing in layers. Very cool! Filmed at the University of New Mexico – Physics Department. This apparatus was developed by John DeMoss and Kevin Cahill of the Department of Physics & Astronomy. BZ's Bovington Tank Museum The Bovington Tank Museum is located by Bovington Camp in Dorset, South West England. Bovington camp is used by the British Army for tank driving and repair training. A Challenger MBT (minus much of the normal bolt on bits) guards the main museum entrance. Inside, I decided to tour the building following the development of the tank path. The Mark I tank is shown in an exhibit which recreated the shock and awe impact of the first tanks on the trench warfare scene.

10 Interesting Futuristic Materials 1. Aerogel Aerogel holds 15 entries in the Guinness Book of Records, including "best insulator", and "lowest-density solid". Sometimes called "frozen smoke", aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon.

Cognitive Dissonance In psychology, cognitive dissonance is the mental stress or discomfort experienced by an individual who holds two or more contradictory beliefs, ideas, or values at the same time, or is confronted by new information that conflicts with existing beliefs, ideas, or values.[1][2] Leon Festinger's theory of cognitive dissonance focuses on how humans strive for internal consistency. When inconsistency (dissonance) is experienced, individuals tend to become psychologically uncomfortable and they are motivated to attempt to reduce this dissonance, as well as actively avoiding situations and information which are likely to increase it.[1]

Twelve Free Chemistry Databases Just two years ago, trying to find free online chemistry databases was an exercise in futility. Now, they're sprouting up all over the Web like wildflowers after a wet Spring. What follows is a far-from-complete roundup of some of the more interesting places to start your chemical search. PubChem- The granddaddy of all free chemistry databases. Search over 8 million compounds by a variety of criteria. Although some PubChem records are linked into the primary literature through MeSH, most are not. Build the Ultimate USB Thumb Drive Toolbox - Page 1 If you like this story, help other people find it by giving it a digg. Thanks! What’s a USB key good for? Carrying files from one computer to another? If you think that’s all, then you’re missing out. USB thumb drives can be used in almost all the ways a regular hard drive can, including storing all sorts of useful apps.

Ionization Photo by: Alexey Lemeshkov Ionization is the process in which one or more electrons are removed from an atom or molecule. The charged particle that results is called an ion. What makes disappearing ink disappear? Carbon dioxide. A common type of disappearing ink is based on an acid-base indicator called thymolphthalein. This is a molecule that absorbs visible light when it is in an alkaline solution, and becomes colorless in a neutral or acidic solution. Thymophthalein To turn it into a blue ink, we add sodium hydroxide (lye), a strong alkali.
