Great one-liners from PF members

The book is free on Amazon and is seriously overpriced. $-$ @phinds​

This is a fun thread...
How come no one debited the hot air balloon thingy:

A hot air balloon can jettison ballast to gain height, but it's still only a hot air balloon

Ah, I know ! It 's not really a one liner, but a composite !
No more mischief -- merry xmas!

A post like this one, by a Mentor, happens regularly here on PF (I especially like the succinctness):

After a Mentor discussion, the thread will stay closed. Thank you everyone. $-$ @berkeman​

If the question happened to be "Find the solutions of the equation $x^2 - 4x + 3 = 0$, and you wrote $S = \{x | x^2 - 4x + 3 = 0 \}$, I doubt that many teachers would give you credit for this answer. $-$ @Mark44

Ha ha!

When the 5V capacitor explodes, scares you, and you try to get away, you don't want to trip and hit your head on the network analyzer cart. $-$ @DaveE

You left off the last part...

Network analyzers are expensive.

And ever since the 13th amendment, you can't even buy us. Only rent.

Who said (appx) that?

 

[jbriggs444]

To explain the joke...

A "network analyzer" is an entity which analyzes networks in much the same way that a computer is an entity which computes. See https://en.wikipedia.org/wiki/Computer_(occupation)

By this definition, I am a network analyzer. The 13th amendment to the U.S. constitution states:

"Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."

So (tongue in cheek and barring the existence of a chain gang in the machine room), if you fall backward onto a human network analyzer, he is not company property but is likely rented for wages.

Thanks, @jbriggs444

I avoided becoming a network analyzer because the modern internet was making it more and more like this guy's job.

I must be honest, I was quite pleased with that one myself!

It can also appear subjective to those who took the time. Whether or not one accepts the continuum hypothesis might be a question only relevant for set theorists, but the axiom of choice decides over an entire branch: algebra. So all who do not believe in the axiom of choice will have a hard time in mathematics.

But I thought you are a constructivist?

 

[fresh_42]

But I thought you are a constructivist?

I generally make decisions that maximize the number of options. I think this makes sense as it restricts possibilities only when necessary. However, my mathematical confession is rather conservative:

AC $\checkmark$
CH $\checkmark$
binary logic $\checkmark$
reductio ad absurdum $\checkmark$
Platonism $\checkmark$

ERH $\checkmark$
NP$\neq$P $\checkmark$

The last two until proven otherwise, but I doubt this will ever happen.

My uneducated guess is that ERH is true, but not P=NP. In any case, maybe your latex on the last point isn't rendering properly.

I'm just finding this thread, but that is awesome. They totally should have used cubits.

Nothing wrong with your eyesight. I corrected the post while you were typing. I often see mistakes not before the final version can be seen, i.e. after "send". The preview is of no help since it alters the edit box. In an earlier version of the software, we had the edit and preview box in parallel which was much better. Now it is an either or so I often push "send" and correct it afterward.

I am terrible at if printing typos. Or also conveying coherent thoughts. A preview would be nice, but I'd likely not pay it notice

I don't understand the fuss. I've measured them before with a tachyometer.

I observed them many years ago with the tachometer a designed many years from now.

In my younger days, I attempted to "troubleshoot" a very large camera flash. The capacitor discharge was, uh, stimulating.

Don't forget incompleteness!

I don't bother completeness. I simply change to the next meta-level.

I thought it was the case that one implied the other, at least almost, but I can't remember which direction. Either way, my "gut" tells me that there is nothing between the set of integers and the set of reals.
