NPL is the UK’s National Measurement Institute, providing the measurement expertise that underpins economic growth and quality of life in the UK.
From new antibiotics to tackle resistance and more effective cancer treatments, to unhackable quantum communications and superfast 5G, technological advances must be built on a foundation of reliable measurement to succeed. Building on over a century’s worth of expertise, our science, engineering and technology provides this foundation and helps to make the impossible possible. We save lives, protect the environment and enable citizens to feel safe and secure, as well as support international trade and commercial innovation. As a national laboratory, our advice is always impartial and independent, meaning consumers, investors, policymakers and entrepreneurs can always rely on the work we do.
Based in Teddington, south-west London, NPL employs over 500 scientists and is home to 388 of the world’s most extensive and sophisticated laboratories
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?
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
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.
@@barrycroucher602 Which division? Just looked at it again, Glazebrook and the buildings next to it in the footage have all been razed - oh well, time marches on.
At this point I am watching all my quarter striking clocks to make sure nothing ever happens to my clocks and the mechanism does not break on my clock.
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?
"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."
Why are you fully covered? I work in this industry and everyone is wearing regular clothes, no masks, any health risks with epoxies or ultrasonic machines?
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).
Not a word of acknowledgement to the Ministry of Silly Walks, whose hard work and dedication over many decades made this amazing breakthrough possible.
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.
@@brauljo We still do stuff like undecillion, and duodecillion. There appears to be no reason not to do so, as it saves unused letters for prefixes in the long run…
