that article is way too long, man

summary pls

skullpatrol

@JohnRennie I have known somebody who thought they had lived too long; but they were in a lot of pain and soon died.

John Rennie

This is a charming conversation ...

skullpatrol

Well, you asked.

John Rennie

It was a rhetorical question

Mostafa

@AccidentalFourierTransform Someone (Forrest Fenn) has hidden a chest full of gold and gems somewhere. and coded the location in a poem. if you crack that poem you can find that treasure (worth $2m)

0celoñe7

4:03 PM

@ACuriousMind what is?

@ACuriousMind on what?

Mostafa

Someone asked this on here too. but on the wrong SE:

webcache.googleusercontent.com/…

(deleted now)

AccidentalFourierTransform

@Mostafa I aint reading no poem for $2M

Abcd

@JohnRennie Yes. Answer is 44/10 = 4.4 kg

John Rennie

@Abcd there you go! Easy :-)

Mostafa

@AccidentalFourierTransform a few people have died in the quest for that treasure

skullpatrol

4:05 PM

I gave an honest answer sir, to your rhetorical question. For that I can not apologize.

Abcd

@JohnRennie in the Atwood machine, the masses are not at equilibrium :( So how is tension same throughout the string. Brief answer would suffice.

AccidentalFourierTransform

@Mostafa it serves them right

who reads poems anyway

John Rennie

@Abcd ah this takes us back to yesterday's discussion.

Abcd

yes

John Rennie

We generally consider the string to be massless in these problems.

Mostafa

4:09 PM

@AccidentalFourierTransform I think if the PSE community works on it for some time with their full potential, we can finally crack it.

Abcd

@JohnRennie Okay, T = ma, a is same therefore T is same for full string

AccidentalFourierTransform

dont be silly, the PSE community has no potential

@Mostafa Who will be given the $2M if we do manage to crack it?

Anonymous

:P

Shing

@AccidentalFourierTransform Most people believe what they want to believe. Except a few people willing to change their minds by arguments and observations.

John Rennie

4:10 PM

@Abcd The string is obviously continuous, but imagine dividing it up into lots of tiny lengths so we approximate the string by a huge number of tiny beads all linked together in a line.

ACuriousMind

@AccidentalFourierTransform True, we're not particularly conservative

Abcd

@JohnRennie yes

John Rennie

@Abcd When we say the tension is $T$ we mean that each of these (conceptual) beads pulls on the beads next to it with a force $T$.

Abcd

@JohnRennie yes

Mostafa

@Blue We can ask the mods for that. espcially ACM The Just

John Rennie

4:12 PM

@Abcd So if you pick a bead somewhere in the middle it is being pulled to the left with a force $T$ and to the right with an equal and opposite force $T$. OK so far?

AccidentalFourierTransform

Anonymous

@Mostafa We don't even know ACM's real name. How can we trust him/her with the money ? :P

Abcd

@JohnRennie yes

AccidentalFourierTransform

$\mathfrak{u(1)}$ or $\mathfrak{u}(1)$?

Mostafa

@Blue OK maybe DavidZ The Great

John Rennie

4:13 PM

@Abcd and because the tension is the same everywhere in the string the force pulling the bead one way is equal and opposite to the force pulling it the other way and the bead ends up with a net force of zero so it doesn't move.

ACuriousMind

@AccidentalFourierTransform the latter

AccidentalFourierTransform

@Blue we do know his real name :-/

Abcd

@JohnRennie yes

AccidentalFourierTransform

@ACuriousMind I thought so

Anonymous

@AccidentalFourierTransform Wut is that? :'D

AccidentalFourierTransform

4:14 PM

@Blue a word or set of words by which a person, animal, place, or thing is known, addressed, or referred to.

ah, what a great movie

Sid

@AccidentalFourierTransform He probably meant what was the name

John Rennie

@Abcd suppose the tension wasn't the same everywhere in the string, that must mean there are beads where the force on one side is different to the force on the other side. But that means the net force on the bead is not zero so the bead will accelerate in the direction of the greater tension.

Abcd

@JohnRennie Right, understood.

AccidentalFourierTransform

@Sid hmm

Apr 5 at 13:42, by ACuriousMind

@Moe We might! My real name is Björn, but I'm not often around the physics institutes these days since I'm writing my master's thesis with J. Walcher who is in the math institute

John Rennie

@Abcd And when the bead moves it stretches the string on one side of it and shrinks the string on the other side of it. That means it increases the tension on one side of the string and decreases the tension on the other side of the string.

AccidentalFourierTransform

4:17 PM

and we also know @Shing's real name

Mostafa

@Blue Or JR. He's arguably the most trusted person here.

AccidentalFourierTransform

Jun 14 at 17:18, by AccidentalFourierTransform

@Shing we'll call you Timothy from now on

Anonymous

@AccidentalFourierTransform Wow. Now we just need his title and his bank account details.

John Rennie

@Abcd Indeed, because the bead is massless (approximately) it accelerates infinitely fast (approximately).

Anonymous

@Mostafa Yeah. JR already has too much money. He won't bother about the petty $2M anyway :P We can trust him XD

John Rennie

4:18 PM

@Mostafa Trusted? Me? :: evil cackle ::

Shing

lol you all can trust me on that $2M. I would use that to invest. earn a bit extra fortune for myself.

John Rennie

Money is like sex - you can never have too much of either

skullpatrol

And one buys the other.

Sid

That ^

AccidentalFourierTransform

yeah, sex definitely buys money

skullpatrol

4:21 PM

That^

ACuriousMind

Can we steer the conversation away from prostitution, please?

Shing

In Taiwan, prostitution is legal. but having a place for prostitution is illegal.

Sid

@JohnRennie I don't trust you. I believe you are a wolf in sheep's skin. :P

(All in jest. No offence)

skullpatrol

The oldest profession.

ACuriousMind

@AccidentalFourierTransform I'm confused as to why mathfrak even works on numbers

John Rennie

4:22 PM

@skullpatrol physics?

Shing

and all prostitution have to be done in "the place for prostitution"

AccidentalFourierTransform

@ACuriousMind I wish I could use \mathbb 1 though

Abcd

@JohnRennie :(

AccidentalFourierTransform

:9

ACuriousMind

@Shing y'know, I kinda meant what I said. Let's not talk about prostitution please.

0celoñe7

4:22 PM

@ACuriousMind WHAT HATS

ACuriousMind

@0celoñe7 Operator hats

Sid

@0celoñe7 you are still not done with that game?

0celoñe7

@ACuriousMind Aha

Shing

@skullpatrol I think an experiment has been conducted that once the researchers taught a group of monkeys about money, then they have that old profession.

0celoñe7

@Sid what?

@Sid I think TW3 has 120 hours of content if you do everything.

I'm at work, not playing games

Sid

4:24 PM

I read somewhere you were complaining about something being too long.

AccidentalFourierTransform

monkeys with money become physicists!?!

John Rennie

@Abcd sorry, the conversation got diverted. The point I was trying to make is that if the tension weren't the same everywhere in the string then the string would immediately stretch and compress until the tension was the same everywhere.

Sid

Considering you were playing games before, I thought that.

@0celoñe7 Increasing the GDP?

Shing

@AccidentalFourierTransform the oldest profession

not physicists

0celoñe7

@Sid nope

AccidentalFourierTransform

4:24 PM

physicist monkeys make more money than me :-(

skullpatrol

Farming is the second oldest.

Abcd

@JohnRennie Replace stone and me with elevator and object please please. So that I can get a good intuitive idea.

ACuriousMind

@AccidentalFourierTransform See monkey do

@skullpatrol We were hunters and gatherers long before we became farmers

Abcd

@JohnRennie Understood this part. Sufficient explanation. Thanks :)

@ACuriousMind My QM prof stopped using hats, but then people asked him to start again

AccidentalFourierTransform

@0celoñe7 you should perhaps tone down the language a bit

0celoñe7

@ACuriousMind Why was that deleted

AccidentalFourierTransform

bc someone flagged it

ACuriousMind

Because it was flagged.

@0celoñe7 Flags are a way for people to say they feel uncomfortable with the conversation if they don't feel they can speak up. Swearing is not bad per se, but if it's making someone uncomfortable you should stop

0celoñe7

@ACuriousMind How am I supposed to know that it is making someone uncomfortable?

It's not the end of the world.

Sid

Eh.. that was a bit harsh..

AccidentalFourierTransform

I wanted to ask him a question

now I'll never know the answer

@skullpatrol oh, I actually have seen that

Shing

@skullpatrol good videos for high school. and they do have an "advanced edition" textbook for year one mechanics + heat . Probably the best text books I have ever read. Very very physics

Mostafa

Again, we're having irregular starring behavior in this room. Everybody please note that

Feb 24 at 19:38, by Mostafa

@0celo7 star != like

ACuriousMind

I didn't realize this room ever had regular starring behaviour.

AccidentalFourierTransform

4:38 PM

there is a lot of regularity

eg, when someone brings this topic up, every message gets starred

Mostafa

@ACuriousMind *behavior

ACuriousMind

@Mostafa *behaviour

Shing

for jokes, starring certainly means: I like it.

AccidentalFourierTransform

^^

ACuriousMind

Well, I have also starred puns for being exceptionally terrible in the past... :P

AccidentalFourierTransform

4:40 PM

anyway, am I really the only one who thinks this belongs on math.SE?

ACuriousMind

@AccidentalFourierTransform According to the review, the only one who agrees with you is peterh.

AccidentalFourierTransform

WHAT!?!

is that even possible?

Well paint me green and call me a pickle

skullpatrol

52 videos and an advanced textbook for engineers, you won't find anything much better on the net

John Rennie

@AccidentalFourierTransform I thought it was relevant enough to physics that it was fine to leave it here. And I thought the answers were interesting, so I want the answers left here.

AccidentalFourierTransform

I dont even like the answer :-P

I really dont see how its relevant to the question

smoke and mirrors IMHO

John Rennie

4:44 PM

I don't think we should be too fanatical in migrating questions to the Math SE.

Shing

@skullpatrol Caltech has two "versions" for the textbook though. both are good. but the "advanced edition" is better (and probably for science schools?) :P (I think they missed writing the advanced edition on that wiki page)

djsmiley2k

@Shing visions, or versions?

Ben Niehoff

por que no los dos?

Shing

@djsmiley2k my bad. I mean versions

djsmiley2k

np, visions gave me a completely different idea ;D

Shing

Ben Niehoff

I'm sure it's better than our Chinese ;)

Mostafa

Have you watched that series? @BenNiehoff

Sid

@BenNiehoff I don't think Chinese is a language. Mandarin is the main language..

Shing

4:47 PM

@BenNiehoff haha thanks

Ben Niehoff

"Chinese" is a family of languages

but yeah

Shing

All Chinese"s" share same "written words", but they have different sounds (and a bit difference in usages).

AccidentalFourierTransform

@Mostafa lol, what are you trying to do?

Ben Niehoff

@AccidentalFourierTransform I have 4 Firefox windows open each with >20 tabs. My browser keeps freezing

Ben Niehoff

eww, why would you need 4 windows open?

I have one window with like 200 tabs

AccidentalFourierTransform

eww, why would anyone use Firefox?

skullpatrol

Limited resources?

Ben Niehoff

I use Firefox because I prefer the way it manages having 200 tabs open

Mostafa

@BenNiehoff Too much stuff to be read later

ACuriousMind

No time to read, must chat in h bar?

skullpatrol

4:52 PM

Sid

@BenNiehoff Here's a funny thing. If you open chrome with >100 tabs, it will show you a smiley face. If you do it incognito, it will give a winking face.

AccidentalFourierTransform

how do you know that?

Sid

.. Let's not get there.. :P

Ben Niehoff

the problem with Chrome is when you have more than about 12 tabs, it starts shrinking the size of the tabs so that you can't tell what they are

Firefox doesn't do that

also, Firefox has a drop-down list that shows all your tabs in a vertical list, with the complete page titles; it makes it really easy to find a tab you lost track of

AccidentalFourierTransform

but Chrome is better in any other aspect, e.g., Firefox doesn't collect user data and sends it to a multinational corporation

Anonymous

4:55 PM

Most of the time, opening more than 12 tabs indicates that you are lazy :D

Sid

... Firefox does that? :o

@Blue That is a wrong conclusion. :P

Ben Niehoff

I mean, I've been using Gmail for years, so I'm sure Google has everything they need on me already

ACuriousMind

@Sid Read carefully: Firefox doesn't

Anonymous

@Sid No

Sid

Oh, right. Chrome does that. Of course it does that..

Ben Niehoff

4:56 PM

Google knows how often you have 100+ tabs open in Incognito mode ;)

ACuriousMind

Oh god, it knows I secretly download postmodernist philosophy?

Ben Niehoff

yeah, I would use Incognito mode for that, too

wouldn't want to be caught with that in your history

@Blue that's not all of the story.

One of the tabs is a Restore Session that contains many windows, with lots of tabs in each of them, probably with other Restore Sessions in them. and this hierarchy continues to tabs from a few months ago...

@AccidentalFourierTransform Handy summary:

The hunt for Forrest Fenn's $2 million hidden treasure

►

vzn

@Mostafa very cool/ impressive paper thx for sharing! are you working somewhere in this area? "The possibility of such a propagation-direction-dependent, or chiral, light–matter interaction is not accounted for in standard quantum optics and its recent discovery brought about the research field of chiral quantum optics." o_O

@EmilioPisanty trying to follow what they mean by "forward and backward propagating light"...

Emilio Pisanty

@vzn in that diagram, forward is to the right and backward is to the left

for more details, nature.com/nnano/journal/v10/n9/full/nnano.2015.159.html

vzn

5:56 PM

@EmilioPisanty is the idea the atoms are spin aligned somehow? trying to wrap my brain around this & formulate meaningful questions...

Emilio Pisanty

@vzn not necessarily

you either spin polarize the atoms to begin with

vzn

> ...the realization of deterministic spin–photon interfaces. ?!? o_O (Lodahl et al)

Emilio Pisanty

or you induce a splitting between the $|+\rangle$ and $|-\rangle$ levels

either way, the spontaneous emission from $|+\rangle$ goes to the right and the spontaneous emission from $|-\rangle$ goes to the left

@vzn yeah, I would take that with a grain of salt

vzn

dont have a nature subscription, am gonna have to follow up with arxiv papers or other material... seems like the popsci coverage has not caught up with this stuff much yet :|
