How can the sun be rising to the north of east rather than a little south of east?
I live half-way up the Northern Hemisphere, so it seems like the sun should always be a little bit south. That’s why moss grows on the north side of trees. Because of my road, I know east is on the right side of the photo. Something ain’t right.
When I started teaching at Normandy in 1995, I was coming off of an engineering career that was mentally challenging because every project was unique and exhausting because of the long hours on site and extensive travel.
I was enthusiastic. Normandy was a great school for me because nobody was paying attention. I could do whatever I wanted, and I wanted to do so many things. I didn’t care about the time, money or effort, if something seemed like a good idea, then we did it. The mural was a good idea.

Today is the 40th anniversary of the Chernobyl Disaster. Today, people know about the disaster, with many becoming familiar from the excellent miniseries Chernobyl. It has an IMDB score of 9.2 and is worth watching on HBO Max.
At the time, it was the radioactive fallout over Scandinavia that got my attention. Ten years later, I had a student who had been there.
7-ton asteroid lights up Northeast Ohio skies, fragments above Medina County
The boom was loud, deep and short. A crash or bang from the highway wouldn’t be such a deep bass sound. With the recent wind, trees have been falling over, but that would be cracking noise that would last longer.
Major Problem in Physics Could Be Fixed if The Whole Universe Was Spinning
Earth rotates, the Sun rotates, the Milky Way rotates – and a new model suggests the entire Universe could be rotating. If confirmed, it could ease a significant tension in cosmology.
This could be a really big deal if it pans out. Nothing would change in anyone’s life, but it could explain phenomena that we can’t explain now.
CNN: The North Pole is moving.
The needle on a compass rotates to line up with the magnetic poles of the Earth. Those poles move, and faster than you’d think. In the past few decades, the poles have been moving about 30 miles per year. On the scale of the entire Earth, that may not seem like much, but closer to the poles, it can be critical.
These are my students on our field trip to Cedar Point for Physics Day in 2011. They are all weird in their own way. I picked the year at random, because it doesn’t matter.
Bill Gates makes a good point about students being over diagnosed, labeled and medicated.
While working out, my brother and I were chatting about goals for 2025. These aren’t New Year’s resolutions that are vague and optimistic, but actionable tasks that are specific, measurable and recorded. It’s the difference between “start working out” and “go to the gym twice per week”.
I’ve been scanning and organizing old photos.
This is from Physics Day at Cedar Point in 2001. Johnny is the student in the center of the bottom row. He was a super kid because he was smart, athletic, had a sense of humor, was polite, mature, good-looking and helpful. Physics came easy to him, but he didn’t brag or show off. I’d call on him when other students were stumped.
