Today I Learned

[MikeGomez]

Short reminder: Please avoid religion as a subject of discussion!

Whether Sagan converted to Christianity or not was his private decision and completely irrelevant to anybody else. I met many mathematicians who were religious, and many who were not. I did not care and neither should you.

Discussing religion is not allowed on these forums. You could have ended the post with that, yet you smuggled in a positive position on the subject which I take offense to. You are telling the public that they should not care.

How about we change the subject from religion to beliefs in general. Beliefs inform decisions. People vote based on their beliefs. They decide what gets taught to our children in school based on their beliefs. They make laws, and make decisions in all aspects of society based on their beliefs. You want to tell people that they should not care?

The statement was, that nobody should care about another person's private beliefs.

That is the definition of private.

Seemed pretty neutral to me. "Don't care" is only an attack on your beliefs if you think people have to agree with you. Granted, saying "you shouldn't care" is a bit of a stretch. I think he meant "you shouldn't care in your posts on a physics forum".

which I take offense to

Duly noted, thanks for letting us know.

You are telling the public that they should not care.

Note that not caring should also apply to such things as gender, age, political stance, colour, creed or orientation.

Not caring is not a judgement; it is the opposite: it is the Great Equalizer.

Why the blocking screen "INSIDER, Become an Insider, Special Introductory Offer,..."?
Should I click on the browser's remove-overlay extension, or should I "Report" the post?

Upon clicking my browser's "Underneath-the-Overlay" extension, I still see I am instructed to "Become an Insider" in order to see or read the article. Your post with the referenced article is a waste!

Sorry - wasn't aware that'd happen (at least, not for certain).

Thread closed temporarily for Moderation and cleanup. The TIL thread is not meant to be a place to encourage bypassing paywalls, IMO...

 

[berkeman]

Okay, after some cleanup, the thread is reopened. Everybody move along past the paywall please, and thank you...

The Today I Learned idea is still fine, but we still cannot move along past the paywall, so referencing the article is still wasted. If some member knows where else is the same article not using such a "paywall", then we would have some progress on this sub-sub-topic.

Weird... I can read the article, provided I allow scripts from businessinsider.com (normally I have most scripts blocked in my browser).

TIL P 52 is right on my door step. (This is NOT a religious post, I am just interested in the history)
https://en.m.wikipedia.org/wiki/Rylands_Library_Papyrus_P52

Whatever your views are this is a very important piece and I have been reading about that and other ancient finds for a few years.
These types of texts are dated by analysing the writing technique, paleography but if you look at the link there is no agreement on the date.
Around 125CE according to my source. Bart Ehrman's lectures and books.
My first thought was, why not carbon date it?

It is supposed to be around 1900 years old, the oldest they have for that book or any in the NT.

The Manchester museum used to have a whole section dedicated to Egyptian History and I visited many times as a child. I have never been to Rylands though.

Edit: Yes it's still there but they are doing some construction work.

. . .that table tennis can be darn exciting!

. . .at least, when it's between the world's greatest offensive player vs. the world's best defensive player

Very cool.

It beggars belief that they can react at that speed.
Consistently too.
Probably only badminton can compare?

TIL Sean Carroll latest podcast is on General relativity. To coincide with his new book.
It hard to visualise as there are no diagrams or equations but it was interesting and he does not shy away from the details.

• Mount Everest's peak is the highest altitude above mean sea level at 29,035 feet [8.85 km].
• Mount Chimborazo's peak is the furthest point on Earth from Earth's center. The summit is over 6,560 feet [2,000 meters] farther from Earth's center than Mount Everest's summit.
• Mauna Kea is the tallest mountain from base to peak at more than 32,800 feet [10 km].

TIL that October is National Sarcasm Awareness Month!

Sarcasm is defined as using irony to mock or convey contempt.
Some call sarcasm the lowest form of humor, but it often requires a quick wit, and the ability to know just when to throw it into a conversation.

Please don't tell V50.

 

[fresh_42]

Please don't tell V50.

Oh, ho, ho, irony! Oh, no, no, we don't get that here. See, uh, people ski topless here while smoking dope, so irony's not really a, a high priority. We haven't had any irony here since about, uh, '83, when I was the only practitioner of it. And I stopped because I was tired of being stared at.

[berkeman]

LOL, Highway to Hell...

 

[fresh_42]

LOL, Highway to Hell...

Would have been my first choice. Or Hell's bells.

Viva Las Vegas is good, too! My sister is a great Elvis fan. I wonder what she would choose. Probably some boring gospel like Crying in the Chapel.

Rather well in fact.

There is at least one astronomical observatory here in Southern California that has its Dome floating in a trough of Mercury.

I can't think a a lower friction passive thrust bearing than that!

Cheers,
Tom
