ThermologyHealth is doing a great job. Just in our own experise and interest of managing calibration for such devices, we're curious what's in plan for calibrating ThermologyHealth device on patients hand, how the deviations will be found and corrected?

A meter is defined in terms of second, one of the basic SI units. Doesn't that make it a derived unit?

There was one where my late father worked at British Steel's Swindon Laboratories at Rotherham I went to the open day in 1969 & still have the brochure about it. With a suitable building & installation, the million volt electron microscope cost a million pounds...the joke was therefore that is cost £1 per volt. My late father was a doctor of chemistry & wortked in a different building there. They loved wasting money...my Dad's laboratory was heated with underfloor electric heating & then temperature controlled swith air conditioners. Richard, UK

How do we establish that the wavelength is in vacuum? And does quantum theory enter into defining what a vacuum is and how to realize it?

Joined NPL 50 years ago this month, and got my first Children's Party "Uncle" badge in January 1975. Not sure if it was the same earlier, but my recollection is that the kids party was always Early January but still with a Christmas theme. The children bundled out of coaches into Glazebrook Hall and into the then-empty Ace room.

why did he say that"currently the ampere is defined in terms of the force between two wires" when the classical definition of the ampere is how much electrical charge is flowing past a given point in one second?
@Correct_Opinion5 ай бұрын
"The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to 2×10−7 newtons per metre of length."

But what if we get to 1000 quetta-? We don't need any more prefixes. We just simply combine the existing ones in a place-value scheme. For example, the Sun is 2 quettakilograms, a star 500 times the Sun's mass is 1 quettamegagram and so forth. After quettaronna- would come biquetta, where we use chemical prefixes to denote how many quetta there are. So a biquettakilogram is 10^63 grams. When we get to the hundred prefix, one could use adapted English, huna for one hundred and tousa for thousand. This gives us for quantities so large and small that we don't need any new prefixes (except maybe huna and tousa).

I just noticed that "ronnagram" sounds like Ron Graham, who created humongous numbers, much greater than 10^27, in his proofs.
@user-fg6ro Жыл бұрын
10^27 is nothing in front of infinity. Nothing. 10^(10^27) is nothing. And so on.

Wrong. The mass of the Sun is 1,989 Quettagrams. You cannot combine prefixes. Otherwise, 1 milligram would be called 1 microkilogram.

I'm still annoyed by the fact that the base unit for mass is prefixed. They should've just made up another unit that's equivalent to the kilogram and go from there, or just use the grave.
