US-0795 World War I National Monument

 I was able to hop over to this park twice, once before, and once after work. Operating portable with a vertical antenna netted me almost no foot traffic attention which was kinda surprising and also kinda nice.

This will all get updated as I go (or not)


Park:

US-0795 World War I National Monument

Getting There:

I walked to the park from my Mt. Vernon Square area hotel. I took transit back though! I walked up a few blocks to the nearest metro station and took the Red Line east where I connected with a northbound Yellow Line to Mt. Vernon Square, the end of the line for that train.


Radio Details:

I used the rig's new configuration that's getting me into  so many urban parks: TouCans and a Stick. Trees on the East Coast seem to have more branches that the ones in San Francisco, so I was able to just place the vertical in the tree with no tape. The branches held it up. The tree still had most of its leaves and was quite wet. I suspect this was the main difference cause of propagation getting so much better at the Pennsylvania National Historic Site less than 200 yards away on the same street, Pennsylvania Avenue NW.

Happenings of Interest 

The biggest happening was that nothing happened. No one really seemed to realize that the rig was there. The cabbies behind me chatted along with each other. You can hear the min some of the QSO recordings. It originally, in the morning, looked to me like buildings were blocking some propagation, but it appears to have been more of a time of day thing as QSOs to the Northwest started top pop up when I returned in the late afternoon.

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...

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. As it turns out, with a little bit of work, the forms that are created by Google Docs can be embedded into any web page. Now, The Goods: Click on the instrument you want turned up, click the submit button and then refresh the page. Through the magic of Google Forms as soon as you click on submit and refresh this web page, the data chart will update immediately. Turn up the:...
