Relativity There was a young lady named Bright Whose speed was far faster than light; She set out one day In a relative way And returned on the previous night. Einstein developed his theory of general relativity between 1907 and 1915, with contributions by many others after 1915. The final form of general relativity … Read more
On the Fifth Day the scientists who studied the rivers were forbidden to speak or to study the rivers. The scientists who studied the air were told not to speak of the air, and the ones who worked for the farmers were silenced, and the ones who worked for the bees. Someone, from deep in … Read more
We had some glorious fall days last week (as well as some much-needed rain). It was perfect weather for the soccer and cross-country teams. I took advantage of the sunshine to visit the lower school at recess. Plans were being made, plots hatched, games created and imagination extended. And plenty of opportunity to run, slide, chase, … Read more
I’m tired of the weasel-worded politicians who trot out “I am not a scientist” when asked a rational question that has the potential to challenge a deeply held, irrational, ignorant ideology. When the threat of a shred of reality, logic, facts, knowledge, evidence, truth, common sense, intelligence or science looms they trot out that lame … Read more
I learned a great deal about eels from Graham Swift’s remarkable 1983 novel Waterland set in the watery fens of eastern England. The history of the scientific understanding of the eel – Aristotle posited that they sprang from the mud – and the mystery of their epic migration to spawn in the Sargasso sea feature … Read more

Strategic plan outcomes can all seem rather formal and abstract until something like this leaps out and grabs your attention. This story is about a high school teacher, his students, their research and how they made a contribution to the scientific study of invasive species in our region.

It’s a good word grit. It’s short, and it has the good old English language virtue of getting right to the point. It also sets my teeth on edge. Why? Well for one, grit – it seems – has become one of those condescending terms that successful people use to describe what … Read more

There are lots of reasons not to like Facebook and I respect all those many people for whom it is just not their cup of tea. But there is one thing that Facebook is really good for and for which, as yet at least, there is no better alternative. And that’s doing a little institutional … Read more
Look at what happens when Mozart catches fire! What I love most about the video is their reactions. And the physics of course. The story of the experiment was first posted in February, 2010. Preston and Jake continued their research into pressure, sound and waves. This video from May 2011 is the result of that … Read more
In contrast to Hobbes’ view in Leviathan that we are destined to lives that are “… solitary, poor, nasty, brutish, and short”, Dr. Dacher Keltner of the UC Berkeley Greater Good Science Center presents the case that we are – in the words of the title of his recent book – “born to be good”. … Read more
From the NYTimes Scientifically tested tests …there are few indications that the multiple-choice format of a typical test, in which students are quizzed on the specific formulas and bits of information they have memorized that year, actually measures what we need to know about children’s education. Susan Engel was also on The Academic Minute on … Read more
It is quite possible that the assigning of grades to school children and college students as a kind of reward or punishment is useless or worse… I’ve discovered an absolute treasure trove of fascinating material: Popular Science has put its entire 137 year archive on line. The quotation above is from Examinations, Grades and Credits … Read more
Click for an UPDATED version of this experiment and with a great new video. It’s always great when a student or a teacher sends along a report, picture or a video of something cool going on in the classroom. Or, as in this case, a cool experiment during vacation. This is a first attempt at … Read more
