College-level science widgets for your website

[Kathy_Bautista]

Have you created a website for your class? Or maybe you have a personal website? If so, be sure to check out the new Wolfram|Alpha Widgets. Here are a few that you may be interested in if you teach college-level science.

Ohm's law
http://developer.wolframalpha.com/widge ... a076197c33
Compute the electric resistance from voltage and electrical current based on Ohm's law.

Photon energy to wavelength
http://developer.wolframalpha.com/widge ... ae32403405
Computes photon wavelength from photon energy, taking into account a (non-dispersive) refractive index n. For using electric permittivity epsilon instead of n, simply type sqrt(epsilon) in the n field.

Maps of Solar System Features
http://developer.wolframalpha.com/widge ... 6bc3533958
This widget allows you to get a surface map showing the location of a named solar system feature recognized by the USGS. Craters, and valleys, and rupes, oh my...

Earth's shells

Gives properties of the various layers of the earth.

Mole Converter
http://developer.wolframalpha.com/widge ... d569853759
This simple widget will convert some amount of a chemical substance into moles of that substance. It also gives the number of particles of that compound.

Cellular Automata
http://developer.wolframalpha.com/widge ... 793141e2b2
A widget to quickly view the results of various rules for cellular automata.

Wolfram|Alpha Widgets are free, personalized mini-apps that leverage the depth and breadth of the Wolfram|Alpha computational knowledge engine. Widgets can do almost anything, from calculating calories in a recipe to solving complex equations. If Wolfram|Alpha can answer your query, you can use it to create a widget.
