Thank you, I am watching you from Iraq ❤

[@MichelvanBiezen]

Great! Welcome to the channel!

[@jakubkusmierczak695]

wow 👏I can not believe my eyes. Mr. Professor it is said that gasoline engine is about 37 % efficient. 5 % is not much seemingly but what about mechanical loses?

[@MichelvanBiezen]

Yes, there are additional mechanical lossed due to friction, wind resistance, etc.

[@jakubkusmierczak695]

@@MichelvanBiezen thank You.

I watched your video on the celestial sphere. So basically every 26k years the north celestial pole will make a circle around the north ecliptic pole moving the equinoxes on different places on the ecliptic? I want to know if I’m right.

[@MichelvanBiezen]

Not sure if I am following your explanation. Perhaps more simply stated, the North Celestial Pole is constantly moving and makes a circular pattern completing the circle every 26,000 years.
