"Static Electric" misconceptionsA list of things which gave me a warped view of Electrostatics. Physics Richard Feynman is a hero of mine. If you like physics, you should get to know his work. You can find a list of Feynman resources here. A note on how I teach mechanics World Magnetic Model Calculator Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019. Choose the geodetic latitude and longitude either by entering the coordinates into the form below (decimal degrees may be entered into the 'degrees' field, and degrees S or W should be entered with a negative sign), or by simply clicking the location on the map. The altitude and date may be set using the appropriate form fields. Clicking on the 'Show result on map' button will display the values for the chosen coordinates in a pop-up window.

There are plenty of physics lessons just waiting to be discovered. Thanks to Andrew Vanden Heuvel and Modern Lessons , you can now learn all about these physics phenomena in a free online course ! I’ve also embedded a bunch of the videos below in case you’re short on time but need to come back later to check out the full course. An important note: these videos were all filmed using Andrew’s Google Glass. That’s why they’re done in a first-person perspective.

Pulsar Sounds (Jodrell Bank Observatory) A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind.
