Just a quick note. Some of the images on posts before Jan 2010 might not be loading. I am working on this, but it might take some time. If there is some old post that you need or link to, let me know and I will fix those first.

BANG! Physics and Art

You should check this out – its free. This is a very creative take on some of the ideas of physics. Think of it as physics meets Dr. Seuss, but with more detailed art work. Created by James Dunbar, it is quite fun to read. Of course, there are some things that are always exactly…

A few blogs

I would just like to take this post and use it to promote some relatively new blogs that I like. Speaking of blogs, I think I have classified blog posts into 3 different kinds. Link aggregators. Chad at Uncertain Principles does this with his Links posts. These kind of blog posts are the glue of…

The 12 RePosts of Christmas

Haiku: The daylight grows short Blogging time is scarce for now Repost is now here I am ready. Bring on the comments about the proper way to write a haiku. Of course, I should warn you that I am technically a professional Haikuer – here is my winning entry to ThinkGeek’s haiku contest Here is…

In case you are not familiar with TWiT, it is a tech-based podcast with Leo Laporte (from the old Screen Savers show). If you want to listen to their discussion, it starts about half-way through the…

After talking about textbooks, commenter Kevin posed the question: which would cost more, printing out a free book or reusing a purchased textbook. Great question. How about some quick estimation (some of this stuff I have no clue about). First, how much do high school textbooks cost? Probably the most popular is Glencoe Physics: Principles…

Leaving a Class for a discussion

I saw this some time ago, probably in The Teaching Professor online magazine thingy. The basic idea is to leave your class alone when they are having a discussion. I have done this a couple of times. Yesterday was the first time this semester. Here is the deal. In this class (Physics for Elementary Education…

I previously talked about textbooks and how there is clearly a problem. The CK-12 Foundation is trying to do something about this problem with the flexbook. Basically, the flexbook allows teachers to create their own text by combining different free content. You can customize a book that closely meets the needs of the class. I…
