Physics on Father's Day

Happy Fathers Day everybody!!!
In honor of Fathers' Day, here are a few physicists who had kids that went on to become scientists themselves.  I know there are far more examples than I've listed here.  Feel free to add your favorites to the comments below!

William Fairbank and William Fairbank Jr.

William Fairbank Sr. performed one of the first two experiments that verified the existence of quantized magnetic flux[6].  He was also one of the architects of the Gravity Probe B experiment.  His son, William Fairbank Jr. is a physicists at Colorado State University who works on the detection of single atoms via photon burst mass spectroscopy (PBMS)[7].

Another one of William Fairbank's sons, Richard Fairbank, founded Capital One Bank which provided the last bit of funding so that work on Gravity Probe B could be completed after NASA quit funding it in 2008.


Sydney and Persis Drell

Sydney Drell proposed the Drell-Yan hadron scattering process in 1970.  The   process was later experimentally verified at the Alternating Gradient Synchrotron and is important in experimentally determining the parton distribution function of hadrons[8].

Sydney's daughter Persis Drell is a physicist at Stanford who has served as the director of the Stanford Linear Accelerator Center.  She is currently working on science with the Fermi Gamma Ray Space Telescope and technical developments and science with hard x-ray free electron lasers[2].

William Henry and William Lawrence Bragg
This father and son team of physicists discovered that x-rays are reflected from crystals at specific angles determined by the wavelength of the x-ray and the inter-atomic distances in the crystal.  This phenomenon came to be known as Bragg diffraction.







Werner and Jochen Heisenberg
Werner Heisenberg[9] was one of the original architects of modern day quantum mechanics.  Specifically he was largely responsible for the matrix interpretation of quantum mechanics.

His son, Jochen Heisenberg, is a professor emeritus at University of New Hampshire where he works on the computational modelling of large nuclei[3].


A Personal Note
My dad and grandfather influenced my decision to go into engineering and physics.  Dad was in the Army Signal Corps before I was born.  Grandpa Pop worked as a welder at White Sands Missile Range and as an electronics instructor at Texas State University.  Talking with them about electronics and computers and rockets as a kid constantly kept science at the front of my imagination.  Happy Father's Day Dad!

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

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 rule can be used to convert a differential operator in terms of one variable into a series of differential operators in terms of othe…

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 simpl…

The Javascript Google URL Shortener Client API

I was working with the Google API Javascript Client this week to shorten the URLs of Google static maps generated by my ham radio QSL mapper. The client interface provided by Google is very useful. It took me a while to work through some of the less clear documentation, so I thought I'd add a few notes that would have helped me here. First, you only need to authenticate your application to the url shortener application if you want to track statistics on your shortened urls. If you just want the shortened URL, you don't need to worry about this. The worst part for me was that the smaple code only showed how to get a long url from an already shortened rul. If you follow the doucmentaiotn on the insert method, (the method for getting a shortened url from a long one), there is a reference to a rather nebulous Url resource required argument. It's not at all clear how to create one of these in Javascript. The following example code shows how:
var request = gapi.clie…
