They have different sets of right answers
Just as in previous summers, I have been teaching a two semester physics course. Each summer course is taught by daily classes for six weeks (compared to two to three meetings a week for 15 weeks).
Here’s a fine book for learning about planets
A few weeks ago, I picked up a new space book from the book bin of a large discount store.
Here are insights on change in climate
I recently purchased a slim paperback largely free of technical jargon on the contentious subject of climate change.
“Global Weirdness” by Emily Elert and Michael Lemonick was produced by Climate Change, a non profit, non partisan science and journalism organization.
Here’s more to learn about the exoplanets
Last week’s column gave a summary of the history of the discovery of planets about other stars and the techniques used to find these alien worlds.
Pulling, tugging helps us to find other stars
When I was in graduate school at Virginia in the 1960s, I heard Peter Vandekamp, director of the Swarthmore College Observatory talk about a possible planet in orbit about Barnard’s Star.
Unknown to us, we host a vast multitude
We have about 10 trillion human cells in our bodies. But on our skin, in our mouth, throat, esophagus, stomach, intestines and colon are about 90 trillion bacterial cells.
Can we count on our sun to be reliable?
One constant in our lives is the radiation from our sun. Of course, how much sunlight we receive from our star depends on the weather, subject to changes each day. But above our atmosphere’s weather layer, the sun’s outpouring of radiation hardly varies.
What are the odds of this happening to you?
I recently purchased an intriguing book with the title of “What Are the Odds?” by Tim Glynne-Johns.
New book chronicles notable early aircraft
I’m writing this column at the time when three planets are close together low in the western dusk but cloudy weather is preventing me and others in the Cumberland area from seeing this unusual formation.
Here’s how physics applies to our lives
Every summer, I teach two physics classes that I find enjoyable. The first course is about motion, forces, rotation, orbits, fluids and heat. The second course covers waves, light, electricity and magnetism.
Since I’ve been doing this for two decades, I’ve tried many teaching ideas. I hope that by the end of each course, my students will understand how physics principles apply to their own lives.
