Note: I think for now, I am going to start each section of this online book with “science stuff:” — just so you know where I’m going.
Aristotle and Reasoning
It’s always fun to start talking about science with the Greek philosopher, Aristotle. It seems certain that there were other…
Working with stuff in 3D can seem complicated — but if you embrace the idea of vectors, everything can work out just fine.
One of the problems you will see in your calculus course (usually in Calc-3) is to find the shortest distance between a point and a line (in…
I really like to write stuff about science. I mean, I think that should be obvious. Well, what about books? Yes, I have published some actual books:
I’m a physicist, not a mathematician. So, when we talk about straight lines in 3 dimensions I find it easier to use real examples. …
Can you learn to swim by just jumping into the deep end of the pool? I think it’s possible — but it’s really not a very good idea.
Have you ever seen a weak swimmer in water over their head? I mean, they have that expression (in over their heads)…
With the introduction of the electric field in introductory physics courses, the first thing is a calculation of the electric field due to a point charge. But who has actually seen a point charge? …
We have a problem with science education, and it seems like it’s getting worse every year.
In pretty much every university for every undergraduate degree program, students have to take a science course. I think even three science courses is very common. But why? Why does a student majoring in…
It’s just part of writing in science and maths — you are going to have to include some equations at some point. Of course, there are many options:
- Write out the equation on paper and take a picture.
- Type out the equation in plain text (like F = ma).
- Use…
Just for my own historical archive, I’m going to share some of the details and pictures from both before and after hurricane Ida. We live in Hammond, Louisiana — which saw some significant damage during this storm. OK, let’s get started. …
I saw this great video on reddit. It shows an incident with a dog on a stand-up paddle board. I’m going to go over all the cool physics things that you can see here. Let’s get to it.
