RE: Off topic but interesting enough to share

I don't think the Bernoulli effect can explain an attraction in this geometry. I would look more at the friction from the water moving in the powerful eddy the jet sets up in the bucket. If this is correct, then a stick held in the center of the bucket near the hose should also be pulled in, and o

Tony, A moving fluid has a lower pressure due to the Bernoulli effect. This principle explains the operation of aspirators and the lift of airplanes. An example of this (I understand) is that if you blow through the hole in the center of a spool then a piece of paper placed at the end of the sp

accepted convention?

In my Britannica Atlas, I ran into a convention I haven't seen before. The number after the decimal point is the minutes of arc. So my latitude would be listed as 37.42 whereas I would call it 37 degrees, 42 minutes or 37.70 degrees. Is this atlas' convention common? John B PS: Well, Tony,

Off topic but interesting enough to share

Fellow shadow watchers, No doubt the following is well known but it came as a surprise to me. While filling a watering can with a garden hosepipe adjusted to give a powerful single jet* I have to PUSH the hose firmly into the can to overcome the reaction from the water je
