Great one-liners from PF members

[PeroK]

Let me guess - you didn't come here to learn, did you? You came here to force upon us all of your misconceptions just to tell us that GR is not correct.

 

[DrGreg]

Until you ... pose a properly defined question, all we can do is to point out that you in essence have asked what to do when the traffic light shows blue.

 

[DrClaude]

It's too advanced for me to say whether it's elementary or not!

Mr. Alertness $\uparrow \uparrow \uparrow$ noticed my 'stealth' quote $-$ I thought I could get by with posting a screenshot without raising much notice $-$

 

[Bystander]

You may have experienced a bit of the PF 'ton of bricks' effect.

 

[Tom.G]

Regarding Power Blackouts.

I'm still not convinced that a billion dollar industry understands the issue better than me. :/

 

[berkeman]

In a discussion about QM Interpretations:

Or to use your metaphor, perhaps it looks, swims and quacks like a duck, but it was not hatched like a duck.

 

[berkeman]

No, because, in the words of Wolfgang Pauli, you are not even wrong.

 

[phinds]

Discovering and teaching are different things.

This was about why we don't learn GR directly from Einstein's papers.

 

[berkeman]

In response to a question from a user about how to derive an equation...

Basically, you have told us where you want to go but not where you are. That makes it tricky to give directions.

Newish poster opened a thread. 'Nuclear disaster (war)' and was worried that the war in Ukraine could lead to Putin attacking neighbouring countries with nuclear weapons 'What would be the worst effects?'

@berkeman replied. "We all die and only alligators and cockroaches survive, thanks for the uplifting post.
Thread closed have a nice day."

Only the survivors of the 'im really worried about the situation in Ukraine' thread, can appreciate the reply I think.

 

[pinball1970]

A wishy washy existential post regarding the Universe. 'Nothing matters, we are just a spec, the universe will die in a heat death,' kind of a thing.

Phinds replied, 'Yes and your point is?'

OP. "Why does it matter if I tell you whether I have a point or not?"

@russ_watters replied, 'It matters for whether or not the thread has value to PF.
Thread closed thus disproving the thesis.'

 

[Borg]

@berkeman replied. "We all die and only alligators and cockroaches survive, thanks for the uplifting post.
Thread closed have a nice day."

Even threads die in a nuclear war.

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?

[DrClaude]

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

 

[berkeman]

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.

 

[pinball1970]

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.

 

[Thadriel]

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.

 

[gmax137]

(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.

 

[berkeman]

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."

 

[fresh_42]

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.
