Unschooling The Windmill and The Railroad

 Here’s another look at what happens with unschooling. 

You set out to spend some time in nature. The eight year-old is starting an animal tracking class, so maybe you’ll commune with nature a bit while you’re out there.

Then, on the way, you see windmill blades, but not on a windmill. They’re. On. A. Train! In the middle of nowhere. Lots of them! They stretch off into the distance. Soooo many windmill blades!


And they’re on a siding! And there’s a little pull off to get over there!!! Woohoo!

So, now, you and the gang—9, 8, and 6 years-old—are going to explore windmill blades! That’ll be fun! You’ve never seen a blade up close before. This’ll be so much fun!

You and the kids head for the blades. They’re walking along the tracks, perusing them. You stop to admire the first blade. It’s gorgeous, framed up just so on the flatcar. There’s a couple of blocks of concrete on the other end of the car acting as a counterweight. Visible between the blade and flatcar, a snow capped mountain peaks into view,. You hear a clanking sound in the distance.

The kids spent maybe a minute looking at the windmill blades? They spent the rest of their time picking up so much stuff along the side of the track. By the time you get there, they've got stakes and a cranker and a flat metal plate and a hammer/bell  and a screw and a lock washer and a nut, all covered in rust. They’re busy using the hammer to drive stakes into the dirt. 


Oh well, they’re having a blast. You get to go back to reverentially studying the windmill blades, right there, in front of you, on the railroad car, just parked out here in the middle of nowhere! So cool!

A few days later, you all go on an explore again. Maybe this time, you’ll spend more time outdoors, maybe you won’t. Maybe you’ll get to see the blades again. On the way there though, you see something huge pulled off on the other side of the road. It’s three of the blades! They’re on trucks now. You stop, with the gang in the backseat to check it all out. They get carried horizontally on trucks, not vertically like they’re carried on trains. The truck driver gives you a bit of a puzzled look, then smiles. He sees the gang in the back. They, of course, aren’t nearly as interested in the windmill blades. It’s all good.

You’d planned, the gang had planned, on exploring next to the tracks again for more railroad tailings, but there’s a railroad truck cruising up and down the tracks this time. So, rather than searching for more railroad parts, the gang finally heads for the forest. To see nature. With their bag of railroad sundries they picked up five days before.

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1.  While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero.  This is typically explained in the following way.  While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare.  That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2].  Cabrera was utilizing a loop type of magnetic monopole detector.  Its operation is in concept very sim

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

Now available as a Kindle ebook for 99 cents ! Get a spiffy ebook, and fund more physics The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems , there seem to be fewer explanations of the procedure for deriving the conversion, so here goes! What do we actually want? To convert the Cartesian nabla to the nabla for another coordinate system, say… cylindrical coordinates. What we’ll need: 1. The Cartesian Nabla: 2. A set of equations relating the Cartesian coordinates to cylindrical coordinates: 3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system: How to do it: Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables. The chain

More Cowbell! Record Production using Google Forms and Charts

First, the what : This article shows how to embed a new Google Form into any web page. To demonstrate ths, a chart and form that allow blog readers to control the recording levels of each instrument in Blue Oyster Cult's "(Don't Fear) The Reaper" is used. HTML code from the Google version of the form included on this page is shown and the parts that need to be modified are highlighted. Next, the why : Google recently released an e-mail form feature that allows users of Google Documents to create an e-mail a form that automatically places each user's input into an associated spreadsheet.
