As of this article, the “teaching tidbits” are now being marked by subject right in the subject line. This will be the last tidbit before our first summer school semester starts on Monday, covering graduate level quantum mechanics with grade school math. In the meantime, enjoy one proof of the Pythagorean Theorem.

## Math Tidbit – Proving the Pythagorean Theorem

## Teaching Tidbit: Alternative Interpretation of the Ideal Gas Law

June 28, 2010 by W. Blaine Dowler chemistry, education, physics Bureau 42 Teaches

Our first full Summer School term launches next Monday, with a virtually math-free course in University level Quantum Mechanics delivered over every Monday in July and August. In the meantime, here’s our shortest teaching tidbit yet: an alternative means of interpreting the Ideal Gas Law.

## Teaching Tidbit: Subtract Your Way to Greatest Common Factors

June 18, 2010 by W. Blaine Dowler education, math Bureau 42 Teaches

The latest teaching tidbit is ready: finding the greatest common factor of two number using subtraction. New topics can be requested and old topics can be found through the Bureau 42 Teaches sidebar.

## Teaching Tidbit: Calculating Logarithms by Hand

June 15, 2010 by W. Blaine Dowler education, math Bureau 42 Teaches

This is our second topic by e-mail request. I also plan to post a method for determining the greatest common factor of two numbers using only subtraction as an operation shortly. You can learn to calculate logarithms by hand here. Also, check out the sidebar on the right for the new “Bureau 42 Teaches” link compilation page.

## Teaching Tidbit: Calculating Square Roots by Hand

June 10, 2010 by W. Blaine Dowler education, math Bureau 42 Teaches

This topic chosen to satisfy an e-mail request. It is entirely possible to calculate square roots without the aid of an electronic or mechanical device more advanced than a pencil. More on this, and about choosing content, frequency, and presentation of these lessons comes after the break.

## Teaching Tidbit: Learn to Convert Repeating Decimals into Fractions

June 8, 2010 by W. Blaine Dowler education, math Bureau 42 Teaches

This summer we’ll see Bureau 42’s first summer school session, which covers graduate level quantum physics with grade school math. I had a blast writing it, and will probably write more educational columns in math, physics, and more. (Summer school topics have already been chosen through 2015, featuring contributions from multiple site authors.) Well, not all topics warrant the full summer course treatment, and cover only single lessons at a time. Those will be posted at random intervals right here. Here’s the first topic: turning repeating decimals into fractions. The algorithm can be followed and applied by just about anybody, though the explanation will be easier to deal with if you’re comfortable with high school math. I am also willing to take requests if there’s something you want to learn. I’m not omniscient, but if it’s math and/or physics, I can probably manage it.

## Why the LHC?

March 4, 2009 by W. Blaine Dowler education, physics Science

Many moons ago, I mentioned that I’d be doing a talk about the LHC for local high schools, and offered to post the core of that talk for anyone to access. I’ve finally done so. If you’re interested in a “nutshell” discussion of the LHC aimed at high school physics students, you can find the contents here.

## Textbook Review – “Fundamentals of Item Response Theory”

November 5, 2006 by W. Blaine Dowler education Science

And now for something entirely unrelated to superheroes.

## Textbook Review – “The Ethics of Teaching”

March 17, 2003 by W. Blaine Dowler education Books

Here’s another textbook review. This one is aimed at Education students, and others interested in decision making in the educational field.

## Textbook Review – “Introduction to Nonparametric Item Response Theory”

July 1, 2010 by W. Blaine Dowler education Books

Yes, I’ve been on something of an education kick lately. This time around, I’ve reviewed an advanced text on item response theory, which is the theory that governs the way people respond to questions, whether they be in class questions or surveys.
