What do you think about this? EFFICIENCY=30-50. Is it bullshit or not?
There are some on the internet about it, people have tried it. Something like an amplifier, but the phase is shifted and you get reactive energy. It's an illusion.

Has anyone thought about the problem?

Okay,

Happy Holidays, everyone!

And my variant of the answer to my own problem, in the first approximation, is uniform distribution, but if we go to infinity, it's probably not quite so. :) Hooray, hooray.

 

I don't know whether it's here or in the wall newspaper...

What is the correct name for this picture?

 

Well yes, pure mathematics.

No offence, Andrew. But without googling it myself, I don't know what it's called.

 
Morning in a pine forest. Shishkin. Imho.
 
Mathemat:

Yeah, pure mathematics.

No offense, Andrei. But without googling it myself, I don't know what it's called.

Come on, there's no hard feelings. I just figured "nothing to do with trading" was the way to go.

Come on, there's no hard feelings. It's just that I've decided that "nothing to do with commerce" is this way.

Ay, máladez!

Parts are turned from metal blanks in the factory's lathe. One workpiece is turned from one billet. The chips that remain from the production of six parts can be melted down to make another workpiece.

How many parts can be made in this way from 36 metal workpieces ?

a boy has 100 bottles of lemonade.

At the shop he can then exchange 10 empty bottles for one full bottle.

How many bottles of lemonade do you end up with?

36 workpieces = 36 parts + swarf for 6 workpieces.

6 workpieces = 6 parts + swarf for 1 workpiece.

1 workpiece = 1 workpiece.

36+6+1 = 43 pieces.

Is it possible to make more or what?
