An Electrifying Teacher

The front page of the Dallas Morning News has a very nice article about a physics teacher, Christopher Bruhn, from Dallas' School of Science and Engineering. He won the AP Teacher Award, a $30,000 prize for excellence in teaching AP courses.

I love the way this guy teaches. For instance, when teaching about electricity, he asks students to come up and receive an electrical shock from a Van de Graaff generator. He tells them, "This will not kill you. Come to think of it, I have not killed a student yet."

Last year, 24 of his students took the AP Physics exam. He told them that if they all passed they could shave his head with the school's letters on it. And they did all pass it, and the shaving can be seen on YouTube.

This teacher exemplifies what I have believed for many years now; that the joy of learning is one of the most important components of teaching and learning. If I were to evaluate teachers, evaluating whether or not the teacher contributed to the students jo…

The Supreme Court Overturns McCain-Feingold Campaign Funding Laws


Congress passed the “Bipartisan Campaign Reform Act of 2002” commonly known as the McCain-Feingold Act. In part, it prohibited national political parties from raising or spending funds that violate federal spending limits, even for state and local races or issue discussion.

It also prohibited broadcast ads that name a federal candidate within 30 days of a primary or caucus or 60 days of a general election, and prohibited any such ad paid for by a corporation, including non-profit corporations.

And Now…

On January 20, 2010, in a 5-4 decision, the U.S. Supreme Court struck down large portions of the McCain-Feingold campaign finance law, especially those aspects of the law that imposed restrictions on corporate spending on political issues. Essentially the Supreme Court said that, “the Government may not suppress political speech on the basis of the speaker’s corporate identity.”

Justice Kennedy, writing for the majority, wrote, "Because speech is an essential mechanism of dem…

Do You Need Math to get into Heaven?

Clearly, nothing is more important than math. The cartoon above is all the proof of this statement that is needed.

(In case you can't read the caption, St. Peter is asking the potential Heaven candidate, "Now the last thing you have to do to get into Heaven is to answer this question: Two trains left Chicago traveling 40 mph in opposite directions and ...").

So, yes, a reasonable knowledge of mathematics is needed to get into Heaven. So as a courtesy to my beloved readers, I have decided to show you how to do such math, so that you will not have to go to “that other place” just because you forgot your Algebra II.

NOTE: don’t stop reading now! This article is written for math-phobics, and anyone else who has not used Algebra since the last century.

So let’s get to it. Here’s the math problem we’re going to solve. Even I didn’t like these kinds of problems when I first studied Algebra. This should encourage you to continue reading.
