“On this day he had lived with that feeling, with death breathing right in his face like the hot wind from a grenade across the street, for moment after moment after moment, for three hours or more. The only thing he could compare it to was the feeling he found sometimes when he surfed, when he was inside the tube of a big wave and everything around him was energy and motion and he was being carried along by some terrific force and all he could do was focus intently on holding his balance, ri...
Food is the meeting place of left and right brainers: Culinary arts call for creativity, but is also deeply rooted in the What, Why and How of basic science—baking powder vs. baking soda, the rising of dough, the falling of a cake, etc. Below, two plays on left brain principles—the Möbius strip and the law of gravity—both executed with right brain flair.
They've been at it for a few years now, but the crazy group of amateur rocket scientists who call themselves Copenhagen Suborbitals have triumphed over adversity, successfully launching their DIY rocket nearly 2 miles into the sky last Friday. The privately funded, non-profit aims to one day send human beings into suborbital space on the cheap, without the need of government budgets and administration.
At the beginning of every class, or almost every class, we do a series of exercises. The Japanese word for this sort of calisthenic exercise isundo. These exercises derive from the Goju style of karate created by Miyagi Sensei in Okinawa in the early part of the 20th Century. In devising these exercises Miyagi no doubt borrowed liberally from the Chinese, whose influence on the southernmost island of the Japanese archipelago was immense.
Homemade circuits are amazing. You can build any kind of circuit on a simple perfboard, as we have seen in previous projects. However, some projects require very tiny circuit boards. We could special order some boards from a printed circuit board (PCB) factory, but that will most likely involve a high price per board and a few thousand miles of delivery service to pay for.
We are embarking upon a new year. As usual, some of us will make "resolutions." There isn't anything wrong with setting goals for the year. It's actually a good idea. It may help focus the energy we bring to life.
Graham Thorpe of Surrey and England demonstrates driving. The straight drive is one of the most classical shots in a batsman's repertoire. Bowlers hate to see batsmen present the full face of the bat as the ball races to the boundary through the offside. The straight drive is about timing and placement rather than power. Drive the ball in cricket.
Make a maze out of invisible dog fence. Have a bunch of people wear many collars on their bodies and tell them they need to navigate their way to the end of the maze. They can see the end of the maze, but if they take the wrong path, they will get shocked. Also either have them wear the barking dog shock collars so that if they leave the boundary they will scream and keep getting shocked until they return to the maze path, or have another method to get them to return inside the boundaries. Bu...
