The Art of Dreaming did it for me. The practice takes you into amazing mental worlds, far outshining everyday existence.

Bless his heart. I pray he comes to his senses. :worry: Medieval scholasticism rises anew. :roll:

Perhaps it's this sort of thing to which you refer: Proposed Math Curriculum in California I have mixed feelings about the issue, having dealt with co...

It's more likely new math extends, generalizes, abstracts what is known, and/or connects what had been thought of as disparate results. That's been my...

None. Probability is a notion having arisen by observation and ideation in this universe.

Are you sure about that? :chin:

Are you the Man of the House, or are you a Man or a Mouse? Investigate the subtle linkage.

Wrong. He would not be seen dead in my image. :snicker:

Yes, proud to say it's 0. I'm happy to shed no light on what you are trying to say. :cool:

Years ago, when I was giving a talk about one of my research projects, Erd?s sat in the front row and listened intently for a few minutes, then lost i...

"Hard and easy is a matter of perspective" about says it all.

Although Crowley came from wealth and later made a living as the founder of Thelema, one should observe he had a wicked sense of humor and it's quite ...

And yet, Cartuna, who is an actual physicist, is banned. :roll:

Can space by itself be distorted? Without its connection to time. :chin:

"Hard vacuum and soft vacuum are terms that are defined with a dividing line defined differently by different sources, such as 1 Torr, or 0.1 Torr, th...

From Wikipedia:

In mathematical research it is not uncommon for ideas to be discovered and rediscovered during the passage of time. An idea may "belong to" its origin...

Can space be compressed? Or merely substances in space? There is a theory of FTL travel which involves compressing spacetime before the moving vehicle...

Excellent post!

Might as well include the NFL, NBA, and MLB regarding athletics at schools.

A bit heavy-handed, but not without merit. :cool:

More or less traditional Europeans. Middle Eastern and African refugees bring in different cultures, religions, etc. I could easily be wrong. I haven'...

I haven't kept up, so I'm not sure how actualism and determinism relate to climate change. I read that parts of Europe have an energy problem now, and...

Well said, Michael. But my impression has been that the Swiss have or had a very homogeneous population. Perhaps that has changed. And homogeneity may...

This is all part of the bigger picture of mob rioting, looting, and smash and grab incidents and the failure of law enforcement to control. Should a r...

Central Planning - to what extent? It worked well for Mussolini and Fascism for a short time after WWI.

Here's a mathematical analogue of a causation chain involving an esoteric kind of dynamical system that most math people would disown (but I have enjo...

From a mathematical POV there are unusual dynamical systems that describe a sequence of forward causal steps extending back in time that account for a...

Just removed instructions for recording episodes of Yellowjackets on Showtime. Ghastly.

Lots of WFH people will be returning to the workplace society simply to be around their fellows. I am a retired prof and a colleague of mine who has b...

I've been a US citizen for 84 years and have never seen the sort of narrative you describe, Enrique. But I'm not saying it doesn't exist. Are you a US...

This seems like a pretty big assumption. Maybe you could flesh it out a bit by citing a country, then giving some examples. Otherwise, your comments a...

A point in 7-D: (x,y,z,u,v,w,t)

Are you speaking of a matter wave or a probability wave in QM? Kenosha Kid is probably out making millions with his guitar rather than really importan...

Will one of you logicians write out in English the defining expressions for abstract objects at the beginning of this article from Stanford? This seem...

Lots of extra dimensions in math - one just defines them. So Tegmark's Mathematical Universe Hypothesis implies all sorts of things.

A touch of humor from Quora Digest a few days ago, apparently a joke that's been around for awhile in academia: The dean, when asked for funding for t...

Thanks. A couple of quotes from the article: "Physically, we don’t have a 4D spatial system, but we can access 4D quantum Hall physics using this lowe...

A link would suffice.

No kidding?

Marco confided he has a masters in physics. With all the pseudo-scientific babble here about collapsing the wave function, superposition, entanglement...

You must not be talking to me.

Simplest example in the complex plane. f(z)={{z}^{2}}\Rightarrow {{f}^{-1}}(z)=\sqrt{z} Single-valued to multi-valued. One could toss in a t for time....

Depends on your definition of "eventually". It's not required that monkeys on typewriters eventually compose Shakespeare.

Just a minor point, but in dynamical systems this is not necessarily so. It's too bad Graveltty has been banned. He has a grad degree in physics and s...

I'm ten years older, so much of what happens will be beyond my awareness. Here in Colorado there is a looming water issue that extends to the Pacific....

I heard part of that. An excellent discussion. I was a meteorologist long ago and my opinion is that it's far more important now to prepare for the in...
