Tomorrow we’ll be wrapping up on our brief tour of the history of electromagnetism. Please make sure to review your notes in case I have a *SURPRISE* for you in class. In the meantime, go watch this lecture: Fantastic.

History of Electromagnetism Part 2 from Sam Harrelson on Vimeo. Keep reviewing your notes!

This week we are starting our quarter-long exploration of electromagnetism. I love this subject and you will too by the time we’re finished in May. So, get a head start tonight and start reading James Clerk Maxwell‘s Preface to his incredibly influential “A Treatise on Electricity and Magnetism” (it was one of Einstein’s favorite books [...]

Antimatter Supernova -The Biggest Bomb in the Cosmos: “We’ve recently seen the largest explosion ever recorded: a supergiant star two hundred times bigger than the sun utterly obliterated by runaway thermonuclear reactions triggered by gamma ray-driven antimatter production.  The resulting blast was visible for months because it unleashed a  cloud of radioactive material over fifty [...]

Go find out why here. Science rocks.

Iceberg breaks in Antarctica not where expected: “With the dramatic crash of an iceberg against a glacier that dislodged a massive new chunk of ice, the mysterious continent of Antarctica once again did the unexpected.” A big chunk of extra credit if you can figure out what happened and why it might matter (both for [...]

Today, we continued our studies of waves and highlighted some of the connections we’ll have in the future with our study of the electromagnetic spectrum. In the meantime, here are our main points from today… The Four Properties of a Wave Frequency = Hz Amplitude = amount of energy/displacement in a wave Wavelength = ? [...]

Using the six simple machines, design a contraption to pop a balloon. – Your contraption must use all six simple machines twice. – You must be creative. – You must detail each of the steps involved in your contraption (i.e. “Step 1: A rock is rolled down a ramp…”) – You must include calculations for [...]

Here’s the main point of our studies today on Work and Power: – Newton (kg x m/s2) = Force – Pascal (n/m2) = Pressure – Joules (n x m) = Work – Watt (j/s) = Power Quiz tomorrow using these formulas. Let me know if you have any questions!
