RIKEN physicists have found a magnetic material that converts heat into electricity with high efficiency, making it promising for use in energy-harvesting devices. The work is published in the journal ...

[In a previous post, I talked about numerical calculations](http://scienceblogs.com/dotphysics/2008/10/basics-numerical-calculations/). The basic idea is to use the ...

It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation. Although the most precise method of simulating and calculating a wellbore ...

It's near the start of a new semester of physics. Many faculty are working on their plans for introductory physics courses. How many tests should there be? What about homework? Do I want to cover ...
