Project GREAT: General Relativity Einstein/Essen Anniversary Test
In September 2005 the kids and I took several very accurate cesium atomic clocks from home and parked 5400 feet up Mt Rainier (the volcano near Seattle) for a full two days. The goal was to see if the clocks actually gained time, even if billionths of a second, as predicted by Einstein's general theory of relativity…
How the pantheon has lasted 2000 years without steel in its concrete
This famous building stands in the business district of Rome--much as it was built some 18 centuries ago. Amazingly, it has withstood the ravages of both the elements and war permitting a firsthand view of a unique product constructed by Roman hands. Now, it is exposed to acid rain and fumes from passing automobiles…

If you put your hand in the Large Hadron Collider...
Several physicists weigh in on what would happen if you were to place your hand in the proton stream of the Large Hadron Collider at CERN. There’s not a definit
Vaccines don't cause autism
The debate is essentially over and the final word is in: vaccines do not cause autism. The results of a rigorous study conducted over several years were just an
There is no nanotech, stop talking about it and start laughing at it
I used to work next to the center for nanotechnology. The first indication I had that there was something wrong with the discipline of “nanotechnology” is I noticed that the people who …
Traffic Experiments -- How to clear traffic jams
Once upon a time, years ago, I was driving through a number of stop/go traffic waves on SR 520 at rush hour in Seattle. I decided to try something. On a day when I immediately started hitting the usual "waves" of stopped cars, I decided to drive smoothly. Rather than repeatedly rushing ahead with everyone else, only…

In one of my sailing classes, one of my shipmates was a Russian ex-navyman who served on a Delta IV class (designated
S. Cook: “This appears to be a relatively serious claim to have solved P vs NP.”
An email I was recently forwarded (a couple of steps removed) from Vinay Deolalikar from HP Labs:
A Breakthrough Cure for Ebola
Ebola is one of the nastiest, most frightening viruses known to man. Its victims suffer fevers, muscle weakness, and other symptoms that pr...
Results of XKCD Color Survey
Who in the rainbow can draw the line where the violet tint ends and the orange tint begins? Distinctly we see the difference of the colors, but where exactly does the one first blendingly enter int…
Sun's path June to December (Photo)
Last June I placed some photographic film into a tin cannister with a small hole punched into its side. The tin cannister was then attached to a clothes pole in my backgarden and left.

The bitter truth about fructose alarmism.
Dr. Robert Lustig, professor of pediatrics at the University of California at San Francisco, is the star of the video above. While he presents some material that’s scientifically sound, he also makes enough errors to warrant a healthy dose of criticism. There’s a ton of material he goes over, so instead of writing a…
A retrospective of the fructose alarmism debate.
After 300 comments and counting, it’s safe to agree with Nigel Kinbrum that my recent critique of Dr. Robert Lustig’s fructose lecture “has caused a bit of a stir in the nutritional blogosphere.” The intense debate (& discussion) that ensued inspired me to re-cap some things I feel were most interesting. There was…
Scott and Scurvy: How the cure for scurvy was lost
Writing about the first winter the men spent on the ice, Cherry-Garrard casually mentions an astonishing lecture on scurvy by one of the expedition’s doctors:
