What is the Universe expanding into..

Well seen that Neanderthal men are no longer around to defend themselves! What if the boot were on the other foot? 😉

I think Neanderthal women could likely rip a homo sapiens apart, based on their higher muscle mass ratio, and leveraged heavy ligature loading points on their bones.

Could this be one of his daughters?

Well that does look a little like Rose, the middle daughter😉

Well, that's completely ruined my fantasy! 😉

Don’t know if I mentioned this in an earlier post or not, but the best introductory set of books on physics is Motion Mountain by Dr. Christoph Schiller

Motion Mountain - The Captivating Free Physics Book

Best of all, you can download all 5 volumes as PDF’s for free. The web books have embedded videos and animations.

Seriously good resource that’s fun to read - minimal math, but it’s their if you need it.

End of plug 🙂

And for the bit more advanced:


The Feynman Lectures on Physics


Pure gold imo.

Thanks guys!

Those resources may help fill my 'chasm of ignorance'! 😎

 

[Disco-Pete]

Huh? You have a chasm? I could recommend a great dentist however it may not be cost effective across the pond. Looks like a root canal. Just make sure he doesn't leave a piece of the bright matter behind, they're known for that.😀

I could recommend a great dentist

Phil McCavity?

 

[Disco-Pete]

See, you guys are always way ahead of us. I have not seen his show. You clearly do not need my help.🙄

 

[Galu]

You clearly do not need my help.🙄

I've been to the dentist several times, so I know the drill!

 

[Disco-Pete]

In that case I'm at a loss in reference to your suggested shortcoming😉

 

[Galu]

You know, we might just be on to a connection here! 😉

The Feynman Lectures on Physics


Pure gold imo.

I have those three volumes in softcover, bought in the 1990s. Tried to read the part in Volume 1 to understand exactly why, when you turn the axis of a rotating wheel, you get a force 90 degrees to the one you're applying. It's what makes tops precess and such. Maybe I'm weak in calculus (had a couple courses in college, and I claim to remember the gist), or just don't quite understand what he's saying.

Check out Professor Eric Laithwaite and his 'anti-gravity' wheel. YouTube

Now this is a question who's answer I immediately grasp. Don't ask me to splain it.😱

I have the Feynman Lectures as well. MM is a better resource IMV and covers a larger range of subjects.

But, both are excellent. MM is far more engaging.

Laithwaite was pilloried when he gave a lecture on that at the Royal Society.

:O

See the lecture on this by Prof Lewin of MIT - it’s on YouTube

Laithwaite was pilloried when he gave a lecture on that at the Royal Society.

He claimed that the outcome of his demonstrations showed that Newton's laws of motion are restricted to motion in straight lines where there is no rate of change of acceleration, and that circular motion has some force all of its own. He was wrong! 😱
