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:

  • One can enter or exit when a cab to reach the floor, even though the demand or any timing. The rosary is not suitable for people who are infirm or disabled. May also be carried no goods in such lifts. This causes this type of elevator rapidly out of favor, but also because buildings are getting higher, so the capacity is no longer sufficient. New are no longer built, old ones are phased out of use. The paternoster still being in force may remain in service as long as the owner wants. However, the lift must be inspected every 18 months and meet the applicable standards.

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?

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.
