Breet breet!

I had just changed into my extreme hot weather walking kit and was on the point of going out when I thought I heard a cricket or cicada chirruping somewhere in the house. Clearly a quick eviction was called for. I stood still to listen and immediately the chirruping stopped too. (This is typical cicada behaviour. Whenever they think you're looking for them, they shut up and concentrate on being invisible). A few more steps to check behind the door were accompanied by a few more chirrups from somewhere nearby. Stop by the door and immediately the chirruping stopped too. This pattern repeated a few more times. Walk, chirrup, stop, silence! Walk, chirrup, stop, silence!

Addidas hot weather track pants have an inner mesh or gauze layer to wick sweat away from the thighs. Worn inside-out by mistake, this mesh or gauze, swishing against itself when you walk, makes a noise exactly like a small cricket or cicada. And it stops when you stand still. You should try it sometime...

How to weigh a car using a tape measure and a tyre pressure gauge

By
There are two pretty good ways to weigh a car: Drive it to the nearest public weighbridge and wait your turn. Look up the manual under General Specifications, ‘kerb weight’ But let's suppose the nearest public weighbridge is fifty miles away and you've lost the manual (and temporarily forgotten how to use public libraries and the Internet) and the burning urge to weigh your car just won't go away- what can you do about it? The good news is, you need hardly any equipment. All you need, for a reasonably accurate result is: a hand-held tyre pressure gauge which can be analogue or digital a retractable steel measuring tape a calculator, pencil and paper, or a good head for mental arithmetic The method Park the car on some clean, level concrete Observe that the car is held up by its four tyres (!) Measure the width of the tread of one tyre: e.g. 6 inches Measure the length of tread in contact with the ground: e.g. 7 inches Work out the area of tread touching the ground: e.g. 6 x

Let's get ACTIVE

  The triode was invented in 1906 by  Lee De Forest and by around 1920 was refined enough to be commercially viable for widespread distribution. It  was the World's first 'Active Device'. It could amplify and oscillate. It (and its derivatives) made possible all of the technologies of modernity – public address, radio, audio/video recording, television, radar, radio telescopy, electron microscopy, computing, the Internet, artificial intelligence. Without active devices, modernity would vanish in a flash. Those who really want to turn the clock back need only abandon science, technology and education. Nature will do the rest.
