• Sleep really is important!

• It's not about how smart you are; it's how hard you work!
  This is just a preview of the Scientific American article on the value of effort.

• What You'll Wish You'd Known
  A Long "Speech" to Students by Paul Graham (good advice for anyone really)

• Test Prep Review
  Free evaluation tests on many subjects and links to tutorials for help; advice on test taking, too!

• Voyager I
  Launched in 1977, Voyager I is now 13.8 billion miles from Earth and in interstellar space. Its 20-watt antenna sends signals that take over 20 hours to reach us and it will continue to send data until some years beyond 2025 when the last piece of equipment is expected to be shut down. Note that a typical cell phone antenna operates on 3 watts.
• Sage Math

  "Sage is built out of nearly 100 open-source packages and features a unified interface. Sage can be used to study elementary and advanced, pure and applied mathematics. This includes a huge range of mathematics, including basic algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, exact linear algebra and much more. It combines various software packages and seamlessly integrates their functionality into a common experience. It is well-suited for education and research. The user interface is a notebook in a web browser or the command line. Using the notebook, Sage connects either locally to your own Sage installation or to a Sage server on the network. Inside the Sage notebook you can create embedded graphics, beautifully typeset mathematical expressions, add and delete input, and share your work across the network."--From the Sage web page

• Cute Baby Animal

• Digital Clock

EM Topics

• TL Reflectometer
  A nice site that allows you to change parameters and see what happens at the load end of a transmission line. By "see" I mean that there's a JavaScript program that creates an animation of both the reflected, transmitted, and standing waves. There are a couple of other nice features as well. Check it out!

• A Tutorial on Smith Charts
  Pete Bevelacqua is a former student in EE 331 who now works at Google. He's a fan of Smith Charts.

• Smith Chart lectures on YouTube by Prof. Cynthia Furse
  This is the first of a series of short lectures on Smith Charts. To see the rest, do a search on cfurse and then look for the ECE 3300 Lecture 12, 12b, and 13 series.

• Cylindrical and Spherical Coordinates
  Use these applets to play with cylindrical and spherical coordinates!

• Some practical applications of electrostatics

• Mathematica EE videos
  Some of these videos might help you visualize topics in EE. If you have Mathematica, you can download the entire notebook. If you don't, you can still check out the Web demos.

• EM and circuits applets by Paul Falstad.
  Lots and lots of Java applets to help you visualize EM, circuits, vector fields, and more!

• Paper about Maxwell's displacement current

• MHD video 1 and MHD video 2.

• Forces between two parallel conductors.

• Magnetic levitation with a superconductor.

• More superconducting levitation (and suspension)!.

• Simulation of earth's magnetic field.
  This computer simulation by C. Gissinger shows the "dynamo effect" in the Earth's liquid outer core. This effect generates the Earth's magnetic field (shown here by looping lines). The radial component of the magnetic field is represented at the surface of the model, which corresponds to the core-mantle boundary ["When North Heads South," Physics World, 25(3), March 2012].

• An explanation of e^(ix) for Homer Simpson
  A YouTube video with a very nice explanation of e and e^(ix) by the Mathologer.
