We used radiation sources and detectors at the steelworks for thickness gauge - you set them on either side of the plate and measure the lost and from that calculate the steel thickness very accurately. I presume in a mine it could be used

I think in late high school, or maybe even after I started my electrical engineering degree, I bought a few of his books from Tandy (the Radio Shack brand here in Australia). They were a great way to get enthused about electronics and encou

The thing is if you can see the result of the light shining on the objects of the ground, it also goes up past your eyes into the sky, only to create the reflective smudge there.

All so called digital devices are really analog devices corralled into operating using binary logic. All it takes is a volt or two applied or removed unexpectedly on those discrete components and you have a bit-flip and possible ensuing may

Yes, a single capacitor will only hold the voltage applied to it. But after charging each one and cleverly arranging them in series you can hold very high voltages with a bank of them. This is what occurs in a voltage multiplier circuit.

I repeated this and got the same result. My follow-up : Q. why do you feel the need to apologize? Is there some correction needed in your arithmetic algorithms? A. As an artificial intelligence, I do not have feelings in the same way

Fun, but needs more rewards than just a high score. Maybe something like a consecutive streak above 90%? Or a challenge where you need to target a given radius. Anyway, nice job. (I recall how my senior hugh school maths teacher was wizz at

Just an FYI, outside of North America, the only shop specifically for work is a workshop. We would go to a auto workshop or a wood workshop. For Aussies or Brits a shop is equivalent to a store (often a small one). And yes go shopping at a

The Nasa Space Flight live streams go into a lot of nerdy detail on selected missions and tests. They seem to refer to spreadsheets that they have built up based on timing vents and lots of telescopic viewing.
