Great one-liners from PF members

[gmax137]

Perhaps it doesn't matter that it all doesn't matter in the end. It's still important now.

The stars are matter
We are matter
But it doesn't matter

 

[Tom.G]

Conundrum.

Where do you honor a a Great One-liner that is created in the
"Great one-liners from PF members" thread?

In short,
a first year physics course doesn't have space and time
for a good treatment of spacetime.

This is kind of like having a blind man paint your house with paintballs. I mean, sure, eventually the job will get done, but it may not be the most efficient way.

I’m sure that when a star is in the process of becoming a black hole, there must therefore be one inside it at some point during the process (correct me if I’m wrong on that). But if so, how long does that take? Could there exist a supergiant star that has a black hole inside it for a long period of time, say, thousands of years, before fully collapsing?

Is it possible for a black hole to be in a star with long term stability, with the star just not collapsing entirely? Like maybe it spins so fast that the outside can stay away from the event horizon?

No.

Yes I learned a great deal from that incredibly educational post, and even more so from the further mockery of a non-physicist daring to not already have a complete physics education.

Apologies. Check your PM

All good friendo. I expect that sort of attitude towards those weirdos who think they’re here to disprove all of science. If I came across that way, that was unintentional.

I just looked at your thread on black holes and you seemed to get some serious answers. Am I missing something?

It was my quote from Orodruin above that amused me. Just some harmless leg pulling till I remembered a post that made me want to smash my tablet not that long ago so I put myself in Thadriels shoes.
All is good now.

Yes I got plenty of great answers.

(I really wish, for fun, somebody would have put T/F "The eigenvalues of a Hermitian operator are always real," on the Minnesota Multiphasic Personality Inventory [MMPI] exam.)

I took the MMPI a number of times (unescorted access in commercial nuclear power units). Unless you have seen the MMPI you probably don't realize how funny @collinsmark is.

From a thread about the Big Bang posted in the Cosmology forum:

It's always a "paradox". Never "something I don't understand"

BTW, is anybody keeping track of which member is quoted the most in this thread? I'm guessing V50 is near the top of that list...

 

[Hornbein]

All good friendo. I expect that sort of attitude towards those weirdos who think they’re here to disprove all of science. If I came across that way, that was unintentional.

Huh. Just now I got a letter from an old friend in which he disproves Bell's Theorem because "scientists got the math wrong." He wants my comments. I'm tempted to tell him it's a work of genius, but might stick with "very interesting."

Yes, that's paradox.

I am not upvoting that. I work very hard and get paid for not producing results.
We all make our contributions.

Quality Assurance?

Quality Assurance?

Not all techs work in QA you know.

I mean I do but you get my point.

I was in a rad protection training class at a power plant. They showed us a little video skit of 4 or 5 guys pretending to work on a valve. They were dressed out in anti-C's and respirators, etc. We (in the class) were asked "what are these guys doing wrong?" The very first answer (shouted out) was, "QC never hands the wrench to the mechanic."

Sure enough, the guy in the back with the clipboard could be seen passing over a wrench.

If feel like I have to defend my people.
If it wasn't for QA, something somewhere may not get specified precisely which means that something could go wrong.
Worse, somebody somewhere may notice.

Oh believe me, I respect QA. I'll let you guess the event sequence that lead my opinion to change from "necessary evil" to "respect and gratitude"...

From @hutchphd

I thought this was very clever.

'Yes but you are creating a Maxwell's demon scenario: half the time the capacitor fluctuation goes the other way. The demon is in the detail.'

 

[berkeman]

Capitalization is important in science and engineering...

M = mega, m = milli. 500 mb is half a bit.

 

[Demystifier]

Bohr is nearly unreadable, precisely because he tried to never say anything wrong.

 

[DrGreg]

In response to a comment that what happens inside the event horizon cannot be observed...

No. They can be observed. Just not published in any journal outside the horizon.

 

[anorlunda]

Significant figures are like training wheels. They help you get started understanding the basic idea of measurement uncertainty, but at some point you take off the training wheels and deal with uncertainty the "right" way.

I know, that's two lines. But I like them.

An award for one-liner of the year?

Yes. I'm not sure how they would do it.
As this is specific probably nominate best three posts to all, then Greg does his stuff and presents us with a poll.
