Joan, I had to look it up also.
When I found the Dutch article, I just kept looking until I found an English article. Made more sense.
Chris, I have never heard of paternoster lifts and looked i up. The original article came in Dutch, I requested English and that was interesting:
Those lifts were so slow and safe, if you touched the one place where you could get hurt, the thing stopped within a second. We had them in older public buildings, and it was fun to make children believe the cage would turn over at the top of the building.
Oh, I also like Google facts Ruth. First time I've seen it.
Interesting elevators Ruth.
The paternoster lifts sound interesting also Chris. I read that they are mostly outlawed because they were hazardous. That reminded me of the busses when I was in Britain 52 years ago. People often got on & off while they were moving. I wonder if they still allow that?
reminds me of the old paternoster lifts
Elevators that go sideways! I had a nightmare like that.
The ampere (A) has long been a sort of metrological embarrassment. For one thing, its 70-year-old formal definition, phrased as a hypothetical, cannot be physically realized as written:
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 x 10–7 newton per meter of length.
In 2018, however, the ampere is slated to be re-defined in terms of a fundamental invariant of nature: the elementary electrical charge (e).*** Direct ampere metrology will thus become a matter of counting the transit of individual electrons over time.
