The ARRL is encouraging all amateur radio operators to write the congressional representatives about a bill before congress that would reduce frequency privleges on the 70 cm band, HR 607 . KD4PYR has created an FB web application that creates a letter for you based on the ARRL's sample letter . Just input your call sign and a letter will be created with your name and address. The application even uses your call sign address to automatically fill in information about your specific representative!

HR607, the bill proposed by Representative Peter King, received some interesting coverage regarding it's effect on amateur radio in USA Today yesterday . It seems the letter writing campaign suggested by the ARRL may be working. The following excerpt is taken from the USA Today article: -------------------------------------------------------------------- "America's first responders, including law enforcement officers and firefighters, these front-line heroes still do not have a national interoperable public safety wireless broadband network," King said. He added that efforts are underway to address concerns of ham radio operators and others. Rep. Billy Long, R-Mo., a co-sponsor of the bill, said he will work "to ensure that we are not cutting any vital emergency services and not adversely affecting ham radio operations." ---------------------------------------------------------------------- Find out how you can help .

The ARRL and AMSAT have recently pointed out that a bill before the House of Representatives would adversely affect frequencies used by amateur radio. The video below describes the ARRL's stance and what you can do. Scroll down for links to a template letter for your representative and the address to send it to. A sample letter can be downloaded from: ARRL Sample Letter For those without Microsoft Word, the letter is copied below. You can send your letter to the ARRL's Washington Representative: John Chwat Chwat & Co. 625 Slaters Lane Suite 103 Alexandria, VA 22314 who will expedite its delivery to your representative. =========================Copy of sample letter=============================== The Honorable ____________________ United States House of Representatives ______________ House Office Building Washington, DC 20515 Dear Representative ________: As a voter in your district and as one of the nearly 700,000 federally licensed Amateur Radio operators across the n...

Anyone know what these are for? Found on a beach in NY.

Just a few quick notes on historical trails I'm finding as I study group theory and Emmy Noether's theorem. The people involved are a bit of a group themselves. The first person I found is Lagrange . He introduced the Langrangian, one of the key concepts of analytical mechanics. It's used today, well, everywhere, from plain old mechanics to quantum mechanics, to quantum field theory. He also laid some of the foundations of group theory working on permutation groups and their use in solving polynomials. That brings us to Évariste Galois . Galois read Lagrange's papers at the age of 15. He later went on to develop Galois theory . Galois theory relates permutation groups of the roots of polynomials to their solvability. Sophus Lie developed Lie groups , provide a framework that is similar to Galois theory for studying the symmetries of differential equations. And that brings us to Emmy Noether. Her paper on " Invariant Variation Problems " applied Lie...

Coincidentally, during Women's History Month, I'm studying Emmy Noether's work on symmetric groups and conservation laws in physics. There's a great Wikipedia entry on her life and work . I found links to her conservation paper in both English and German at UCLA's Women in Physics site . There are a few books about her life and her theorem that look interesting. I'll be reading "Emmy Noether's Wonderful Theorem" later this month. She spent her last few years at Bryn Mawr College a few miles from Philadelphia. Her ashes are scattered below the cloisters there. If you'd like to travel to the college, a map and transit information is included below. It turns out that it's pretty simple via SEPTA once you get to Philadelphia. View Emmy Neother in a larger map
