Is 'curl E' a standard notation nowadays? When I was at uni we used 'rot E'.
- jonlong 2y agoWiki says that curl is standard in North America, while rot is common in "the rest of the world, particularly in 20th century scientific literature". As a North American I can confirm that I was always taught curl and only saw rot in older books. That said ∇× is what I've seen most commonly overall.
- dboreham 2y agoScotland we used curl. I never heard of rot. Although Maxwell was Scottish, the vector analysis notation was invented later.
- xanderlewis 2y agoIn England we also seem to use curl. I’ve similarly never heard of rot.
- defrost 2y agoDitto 1980's era Australian physics and engineering courses. Throw in a right hand thumbs up for "direction" of curl (fingers indicate rotation, orthogonal thumb direction is orientation) and other results about paths having to have a zero rotation between places with opposing rotation, etc.

- xigoi 2y agoI’m from Czechia and we mostly use rot, sometimes ∇×.
