Heave Ho and Up She Rises!

seagullIt was the wrong season for whales. It was the wrong month for sea lions. The gulls only tolerated me and to be true, I enjoyed them only within my limited fascination for the inexplicable red spot on their yellow beaks. For the first 20 minutes, a lone brown pelican held my attention as it repeatedly wheeled over and anchovied point-first into a school unaware of summer vacation.

I was cabin cruising Pacifically with a friend. A pleasant sun, some wind, and water that peaked and curled like Seasicknessicing on a cakemaker’s masterpiece. Then the first symptoms appeared. Laughing into my Dos Equis, I guessed out loud that too much clean air could make a man dizzy, his knees a bit watery. I sat down and stared at the horizon, limply watching headache and nausea bobbing grimly across the deep, smelling my fear. Irrevocably, I released my beer and flopped down onto a deck cushion accustomed to human instability. I looked to my friend for help. He smiled wanly and ruddered right, turning the sun out of my face. He has a kind heart, but there was nothing else for him to do. I was seasick. Continue reading “Heave Ho and Up She Rises!”

P(achy)casso? — Elephant Painting an Elephant

An excited correspondent sent me a link to this video of an elephant painting a picture of an elephant.

It is an engaging video, and comments on other websites from eyewitnesses (most often reporting their visits to Thailand) to such “artwork creation” give good evidence that this is not a fraud. The elephant is actually holding the brush to the paper and moving it with precision. Continue reading “P(achy)casso? — Elephant Painting an Elephant”

NCAA Final Four Math

NCAA 2008 Final FourBy missing their last shot, tenth-seeded Davidson lost to top-seeded Kansas 59-57…and for the first time in NCAA tournament history, all four #1 seeds made it to the Final Four.

What are the odds of that happening?

My assumptions are arbitrary—I admit that—but here’s the math.

How to Fix Intermittent Errors

g4Today my four-year-old Mac G4 laptop began acting its age.

Groups of pixels jittered chaotically in horizontal regiments, sometimes covering the screen. Then, without anodyne application, the problem would disappear. And just as unpredictably, reappear. Further investigation revealed that these video measles increased or decreased as a function of manual pressure exerted on the case.

What I had was a screw loose…an intermittent error…notoriously hard to put right.

When I was in my 20s, I worked with an engineer who had a method for fixing such problems.

For any electronic device with an intermittent problem…

1) Measure the length, height, and width.
2) Add them together and multiply by two.
3) Hold the device that distance above a hard surface.
4) Drop.
5) Now the problem will no longer be intermittent.

Laptop, heal thyself!

Or else.

Smallness

power drillWhen Richard Feynman came back to Ojai’s Summer Science Program in 1960 for a second, unscheduled visit, his topic was what he called “smallness.” Today that field, in which he was a visionary, is called nanotechnology.

Having been mesmerized by Feynman’s brilliance and wit during his talk on Relativity a couple of weeks earlier, we 26 science/math nerds were energized when he began by asking us to… Continue reading “Smallness”
