How does gravity in relativity really work? What s wrong with the space-is-like-a-rubber-sheet analogy? and Well, to be fair, the rubber-sheet analogy successfully communicates one profound idea: Mass changes geometry. Geometry influences motion. That is Einstein s central insight. Instead of saying, The Sun exerts an invisible force, Einstein says, The Sun changes the geometry of spacetime,…
Musk s return to the moon plan still seems dangerously over complicated. Is there any easier way to get humans safely back on the moon, much faster, with far fewer launches? I d love to get an analysis of this from someone good with Kerbal or similar software. I worked this idea out over time with Claude Continue reading
For more than four centuries, physics has been animated by a single powerful idea: that the bewildering diversity of nature arises from a very small set of simple principles. We call the project to uncover these simple ideas, unification. And the remarkable fact is that time and again, the history of physics has rewarded those Continue reading
Why is teaching art intrinsically important to being human? Some would have us believe that we should have art education in our schools because it “improves neuroplasticity,” or “develops pattern recognition,” or worse, correlates with higher test scores. To some extent all of that may be true. Yet if art education were to be defended Continue reading
Symmetry is an important concept for understanding how our universe works. Symmetry lets us see what stays the same when certain conditions change. Symmetries are powerful because they reveal deep patterns in nature. They allow us to make predictions. Many basic laws of nature e.g. conservation of energy and of momentum arise from Continue reading
When did the ancestors of native Americans arrive in what we now call New England? Their earliest confirmed presence in New England is about 12,000–13,000 years ago (10,000–11,000 BCE.) This is when the last Ice Age was ending and the glaciers that once covered New England had recently retreated. There are contested hints of human Continue reading
Why is music intrinsically important to being human? Every year I read yet another article trying to persuade us that we should have music education in our schools because it “improves neuroplasticity,” or “develops pattern recognition,” or my personal favorite (sarcasm intended) “correlates with higher test scores.” I do not deny any of Continue reading
Regions of Massachusetts: Sudbury, Assabet and Concord river watershed and the Nashoba Valley. This area extends from part of the area here shown as the northeast, into part of the MetroWest region. Nashoba Valley is a commonly used regional name in north-central Massachusetts around the Route 2 and interstate 495 area. To be sure, it Continue reading
“Housing affordability is a shared problem that is getting worse across the country: 80 percent of Americans living in rural communities believe housing affordability is getting worse in their community, while 72 percent of residents in urban areas feel the same. This sense is shared across all demographics, regardless of partisan identification, race, age, gender, Continue reading
Article archive for students from They’re using the techniques honed by oil and gas to find near-limitless clean energy beneath our feet, CNN, 7/22/2025 Deep beneath Utah’s desert soil, an oil drill bored through the Earth at a blistering pace earlier this spring. Gnarly looking drill bits tore through granite at around 300 feet Continue reading
