Unfortunately, GoDaddy bought out my webhost, WebFaction. This has meant that I have had to change hosts. It has been a struggle to find a webhost that matches WebFaction's performance, support, and price. This also means that this site has had some periods when it was not available, and certain resources are still not available. I am hoping that I will have all these issues sorted out by February 1, 2019. I apologize for any difficulties this may cause you and I thank you for your patience.
I have loved science since I was a small child, so it was only natural that I majored in biology when I went to college. Most of the resources you’ll find here are the results of class notes, or of my teaching and tutoring experiences.
Be sure to visit my science blog when you get a chance.
I also have a gallery of science education photographs available on my photo gallery.

Chemistry is the study of the structure, properties, and reactions of the chemical elements and the compounds they form.
Physics is the study of matter and energy and how they interact. More so than any other field of science, mathematics is the language of physics, so a strong background in mathematics underpins a solid understanding of physics principles. I have seen many high school students do poorly in physics not because they couldn't do the math, but because they didn’t understand what the math was telling them.
At the college level, you generally have a choice between algebra-based introductory physics courses, or calculus-based intro courses. If you are a science or math major, I highly recommend that you take the calculus-based courses. If you understand the math, you will understand the science better, and it will put you in a better position for later opportunities.
