Great one-liners from PF members

[Hornbein]

We already have it in French.

Well dang. I've had this happen before. Last time it was Apocalypso. Someday soon anything you can imagine will already be there. Then what?

A ChatLSD search turned up the Charles Schwab brokerage. Who knew?

There was a ChatLSD on Instagram that has been removed.

 

[gmax137]

Who knew?

Timothy Leary?

This process of continually updating one's knowledge of a subject is called learning. It's the opposite of religiously adhering to an established view in the face of evidence to the contrary.

 

[Swamp Thing]

... if only there were some way of searching for information on the internet

This deserves to be in this thread in its own right, yeah?

I might borrow this one, if you don't mind.

That was my complaint about the title "Breaking bad."

About e-mail scams, banks, and police.

...is better to learn locksmithery than rely on somebody else to guard your stuff.

In a discussion about a woman who had 69 children from 27 pregnancies (all multiple births):

27 x .75 = 20.25 years
That so much more reasonable.
Very fertile, but also efficient.

 

[berkeman]

About questionable results in a new paper:

At least it puts the woo in woo hoo.

 

[berkeman]

When trying to help an EE student with analyzing fairly simple circuits, and they keep trying to use SPICE to guide their learning...

You'll learn a lot more about electronics if you solve simple circuits with math before you simulate them. Simulations only give you answers, not reasons.

 

[jack action]

As a rule of thumb, when the first thing someone tells you is that their invention isn't a perpetual motion machine (before you can even think to ask), that means it's a perpetual motion machine.

 

[Borg]

That sounds like a conversation that could go on forever.

 

[gmax137]

There is no universal Least Action path to happiness.

 

[berkeman]

This one is way over my head...

The fact that you can buy an oven mitt at all is proof of quantum mechanics.

 

[Vanadium 50]

There is an explanation in that thread.

 

[berkeman]

From a thread where a math major is complaining that when he had to take a mandatory Physics course, he found the math in it to be very non-rigorous and not based on axioms...

Do you already know what the axioms of nature are?

 

[berkeman]

While trying to give a B-level reply to a question about the speed of propagation of changes in spacetime...

It's actually quite difficult to come up with a well-defined way of saying what you are trying to say without either resorting to postgrad maths or saying something not really accurate and crossing your fingers behind your back and hoping nobody asks awkward questions.

 

[Rive]

From a thread where a math major is complaining that when he had to take a mandatory Physics course, he found the math in it to be very non-rigorous and not based on axioms...

From the very same thread:

I guarantee any stroke QM could give a mathematician, an engineer could make worse.

 

[Tom.G]

From a thread discussing WiFi and Routers, @Vanadium 50 observed:

The number on the box is really mostly irrelevant. "Up to X Mbps" just means that they promise you won't get X+1.

 

[pinball1970]

Vanadium on a post regarding David McCallum TV series.

The Invisible man" 1975 series

V50 "I could never see him in that role."

 

[pinball1970]

I could never see him in that role.

Not to be outdone our talented, the lovely,our very own @DennisN !!
"Also, as far as I can remember, the portrayal of the character was rather transparent."

 

[berkeman]

From a discussion in the Engineering forums about a part that a new user wants help designing:

If you have ignored the obvious failure modes, and so build a house of cards, that design failure may later be investigated by a Coroner.

 

[berkeman]

From a discussion thread in the Academic Advising forum where a newbie is asking for advice about learning resources...

As others have noted, learning physics by reading alone would be like learning to play piano by reading a book. It simply is not possible.

If I tell you that a scribblex is a fooddely scribblex if the warghandle is zero you might (reasonably) complain that this does not help you to understand what I'm talking about.

 

[Vanadium 50]

Decisions made by emotional inclinations can be risky or just dumb.

 

[Haborix]

Exactly. How many times have you grabbed the vanilla ice cream only to beat yourself up later knowing you should have gotten chocolate?

 

[PeterDonis]

How many times have you grabbed the vanilla ice cream only to beat yourself up later knowing you should have gotten chocolate?

I solve this problem by not liking chocolate ice cream.

 

[topsquark]

Agreed. IMHO, (French) vanilla is the only real flavor of ice cream!

-Dan

 

[Vanadium 50]

Emack and Bolio's "Chocolate Moose" ice cream is excellent. But their "Vanilla Bean Speck" is outstanding.

 

[Haborix]

Well, if we are going to be picky, I’d almost always take butter pecan over either vanilla or chocolate.

By @Baluncore in Engineering and Computer Sci Homework Help

Be productive, play LTspice simulation of circuits, not video games.

 

[phinds]

Well, if we are going to be picky, I’d almost always take butter pecan over either vanilla or chocolate.

I would agree w/ you about that but then we'd both be wrong.

 

[berkeman]

Nice metaphor by V50 when giving advice in the Academic Advising forum to a user who is considering switching majors into a more narrow specialty...

If you shoot for such a narrow target, what happens if you miss?

 

[phinds]

Well worth keeping in mind, I think:

The fact that quantum systems behave highly non-classically in some cases does not mean they do so in all cases.
