Things you were taught at school that are now wrong

I got the cane/blackboard ruler a good few times and I wasn't even a bad kid. I just liked a laugh in class.
I was giggling once and the teacher pulled my head back by my hair. He also lifted a boy by his ears from the chair, very dangerous and could have caused physical problems for the rest of his life. Psychopaths who were paid for doing what they enjoyed, abusing children.
 
Bad behaviour deserves the cane.
Unfortunately it sends the message you can physically abuse someone and that’s ok. I can understand why people think this is acceptable considering some of the thugs who cause so much pain and misery these days and there’s no deterrent. I admit I would probably change my views if my grandchildren were ever abused. I would flog them myself, Sharia style. A society is judged by the way it treats its prisoners.
 
The school atlas had countries called Yugoslavia ,East Germany, West Germany,
and USSR.
We were part of a European Union.
Jimmy Saville and Rolf Harris were on telly teaching children how to be safe.

Boys were taught practical subjects like Woodwork, Metal Work, Technical Drawing and Sciences.
Girls did Domestic Science, Needlework and Motherhood!
Not sure what happened after that?
 
It travels both inside and around the wire. Without the electro magnetic field surrounding the wire you have no electricity. The electrons do flow in the wire but that doesn't create electrical energy. The magnetic field creates the electrical energy.

Considering that light and electromagnetism are the same force and light doesn't need a wire then neither does electricity. Electrical energy is a cross factor of electrons and magnetism. If you then consider ac current it just wouldn't work if electricity worked the way you are taught in schools. You would have as much energy going back to the power station as leaving it. The energy is directed radially outwards in appliances even though the electrons are moving in 2 different directions. Combine it with magnetism and you get a cross product vector that lights a bulb.

I can see why they don't teach this in schools
They do now
 
Be honest now Jack, you looked that up cos you thought I was talking bollix😁. He explained it better than me but he did have visual aids.
Pure coincidence - he (Veritasium) posted it on FB yesterday and it came up on my feed as I follow him. It's an edited version of an earlier video he produced, which sparked (sic) some controversy. If you look at this link you'll see lots of videos from people who think he's got it wrong
