user54412

no questions I feel like answering

user54412

nothing left to review

user54412

nothing left to vote on that I haven't voted on already

user54412

How am I supposed to slack off?

ManishEarth

06:28

@ChrisWhite reddit :P

also, ask stuff

also, discover new sites on the network

user54412

@ManishEarth well, I just asked :P:P

user54412

also, I take a small amount of pride in not using reddit or quora or anything popular like that

user54412

and I already lurk on many SE sites

ManishEarth

@ChrisWhite Meh, Quora's actually fine if you keep in mind its purpose and follow the right topics

But yeah, it doesn't hold a candle to SE in terms of informativeness

user54412

yeah... it's really popular with everyone I went to undergrad with

ManishEarth

06:33

same here

Reddit: /r/funny is where I go when the Internet can't serve my slacker needs

user54412

so facebook tells me all about what they vote on already

ManishEarth

Yep

user54412

as for the other SE sites, I've reached the point where I don't even understand how there are sites for some of these topics

user54412

tridion?

ManishEarth

yeah, I was O_0 too

magento

expressionengine

drupal for that matter

user54412

06:34

yeah all those

ManishEarth

Still, there's Cross Validated

user54412

not to mention bitcoin

ManishEarth

And Mathematics

@ChrisWhite That actually makes sense

user54412

how is there a Q&A for a fake currency?

ManishEarth

Well, it's not fake :P

user54412

06:35

well, the internet has ascribed value to it I suppose

ManishEarth

But bitcoin is a rather complicated system; it's not like the dollar bill (which has 20 features or so)

@ChrisWhite Exactly, and that makes it money

user54412

the fact that that works just depresses me :(

ManishEarth

There's also Science Fiction & Fantasy

@ChrisWhite Why?

user54412

Oh I read that already

ManishEarth

I find the concept interesting

user54412

06:36

as well as stats, scicomp, rpg, and others

ManishEarth

I mean, they've managed to use crypto in a way such that it is less lucrative to crack the crypto

Usually encryption has a breaking point. Give me a supercomputer and a year and I'll crack it. HOWEVER, with Bitcoin, it is far more lucrative to use your supercomputer to help the system rather than against it.

user54412

people are making money - large amounts of it - not by solving real problems, but by creating new ones

ManishEarth

Well, the "service provided" could be to "help create and maintain a currency network"

user54412

and my understanding is their problems are of the sort that the only people truly able to earn bitcoins are those with dedicated, research-level hardware

ManishEarth

Think of those people as mint workers

@ChrisWhite Yep

user54412

06:39

I don't trust governments one bit, but I trust endeavors like bitcoin even less when it comes to equitable distribution of resources - it seems like it's meant to maintain an elite aristocracy, rather than infuse an entire economy

ManishEarth

Thing is, Bitcoin solves many problems too. There are problems with the current infra of money transfer over long distances

@ChrisWhite How?

Miners don't get much, even with high end hardware. Unless you have an ASIC (and there are like 100 of those right now)

And the money does seem to circulate (see blockchain.info, lots of non-internal circulation)

user54412

mmm

ManishEarth

I haven't actively participated in this -- I think I have a few ten thousandths of a BTC stashed somewhere -- but I know people who do

Wait, why is this worth anything?

Bitcoin in plain English

user54412

I do see those arguments, but US dollars aren't just fiat currency, they're fiat currency backed by the US government

user54412

if the US dissolved, all that money would become worthless overnight

ManishEarth

06:44

Yep

user54412

so bitcoins seem a bit... unstable ... in that sense

user54412

there isn't a several-centuries-old nation state's inertia behind them

user54412

also, "open data" is apparently a concrete enough topic for a site?

user54412

it may be a great thing, but what exactly does a researcher of open data, well, do?

user54412

maybe the lesson here is that most of the planet is moving toward solving problems we invent for ourselves, because there isn't anything left to solve

user54412

06:48

i guess that's a good thing

ManishEarth

@ChrisWhite Which is why I'm not going to switch to bitcoins any time soon

However, remember that bitcoin can't be brought down by any single entity (collapsing or not)

user54412

true

user54412

i'll admit there are the seeds of a good idea there

ManishEarth

The liquidity may change if governments take drastic measures

@ChrisWhite Yeah, nice way of looking at it :)

user54412

but i don't think most of its creators are well-versed enough in the nuts and bolts of macroeconomics

user54412

06:51

saying "inflation is bad" is really only correct to zeroth order at best, for instance

ManishEarth

@ChrisWhite Possibly

They got the money=liquidity bit right

But I think what they had in mind was to partially reinvent economics, or have a system in which the economics is radically different

(My net connection's hiccuping, so I may disappear)

user54412

yes, as did the soviets once upon a time...

user54412

:P

user54412

@ϚѓăʑɏβµԂԃϔ Good morning!

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite I was busy reading the previous conversations... Hah... Gd n8 (Hope I'm right) :D

ManishEarth

06:55

@ChrisWhite Yeah. And bitcoin has its own form of inflation

Ϛѓăʑɏ βµԂԃϔ

BTW, you've started to ask homework questions..! :P

ManishEarth

Btw the original paper doesn't list anything about inflation

Ϛѓăʑɏ βµԂԃϔ

> What would be the new eccentricity (and, why not, semi-major axis) after the collision?

ManishEarth

However, what Bitcoin protects itself against is being affected by government policies. The value of the dollar is affected by every executive decision the government makes

user54412

Lol - if I ever have students of my own, their homework will be awesome

Ϛѓăʑɏ βµԂԃϔ

06:56

@ChrisWhite: If you've had left it as it is (without adding any of your addup - which you mentioned considerations), I'd have VTC'd it as too localized :)

user54412

@ManishEarth indeed - I guess they guard against both the good and the bad of government interference

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite: BTW Chris, you've worked in Palomar... Right..?

user54412

the pessimist in me thinks that's good - governments will often screw up monetary policy because they put politicians rather than economists in charge

ManishEarth

Me?

@ChrisWhite Exactly.

Ϛѓăʑɏ βµԂԃϔ

@ManishEarth Not you..!

user54412

06:58

but the optimist in me hopes that a wise government can pull strings just in the right way to make improvements to the economy

user54412

@ϚѓăʑɏβµԂԃϔ yep

user54412

I've observed from there a few times

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite So, it had this flickering problems... Isn't it?

user54412

flickering?

Ϛѓăʑɏ βµԂԃϔ

(it's an old-timer ... from WWII period, I think so)

@ChrisWhite that turbulence, twinkling :D

user54412

07:00

well, Palomar actually has one of the world's best adaptive optics systems installed right now

ManishEarth

@ChrisWhite Pssh, all the economists do is assume that people think the same and then try to do math.

user54412

they can get rid of pretty much all the atmospheric problems

Ϛѓăʑɏ βµԂԃϔ

Ahh...

user54412

the only problem is it's difficult to get permission to turn on the guide laser

ManishEarth

Isn't that important?

Ϛѓăʑɏ βµԂԃϔ

07:02

@ChrisWhite Why's that so..? Is it restricted to grads too..?

user54412

you see, adaptive optics needs either a bright star near to what you're looking at, or a powerful laser to make an artificial star at the top of the atmosphere

ManishEarth

Oh right the bright star

Ϛѓăʑɏ βµԂԃϔ

Twinkle twinkle...

user54412

but the Federal Aviation Administration (the people who control planes in the US) doesn't like lasers

ManishEarth

ah

user54412

07:03

you actually need to hire 3 or 4 people to visually look out for planes whenever the laser is on

ManishEarth

wow

user54412

in addition to filing plans weeks in advance

user54412

and being told where not to point so you don't hit military satellites

ManishEarth

Why not just designate it a no-fly zone? Guide lasers are pretty important iirc

user54412

(of any nation - if Palomar accidentally blinded a Chinese spy satellite, there would be international problems)

Ϛѓăʑɏ βµԂԃϔ

07:04

@ChrisWhite Hmmm... Now, I get the abbrev. of FAA - I've heard in many movies like "FAA landed all flights, they hacked FAA too, etc."

user54412

it's not really a problem - just a stubborn bureaucracy

ManishEarth

So the REAL threats to our planet are the astrophysicists/astronomers. Not the particle physicists with their black-hole-producing-LHC. :P

user54412

but all that aside, Palomar is also limited because the city of San Diego has grown over the last 60 years

user54412

the skies aren't too dark there anymore

ManishEarth

@ϚѓăʑɏβµԂԃϔ FAA in the US, JAA in the EU, DGCA in India

Ϛѓăʑɏ βµԂԃϔ

07:06

@ManishEarth Ohh... Do we have one..? I should find a laser now...

user54412

but it's a very nice, hospitable telescope - there is an old-fashioned lodge for astronomers, with a permanent cook who makes whatever you want for dinner

ManishEarth

@ChrisWhite Well, places like Keck aren't going to be light-polluted any time soon

@ChrisWhite nice!

user54412

@ManishEarth Arecibo = radio :P

user54412

it's a whole different thing

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite How many days or months do you stay there..?

ManishEarth

07:07

@ChrisWhite Yeah I just realized that. Keck then

user54412

I've only been to Palomar for 1-3 day stretches, some people might do longer

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite Yeah... Arecibo is now with NANOGrav too....

user54412

Keck is better

user54412

Chile is even better actually

user54412

all the new telescopes are going there - they have deserts on top of extremely high plateaus, with smooth air flowing from over the Pacific

ManishEarth

07:08

ah

user54412

basically Chile has the best observatory sites in the world, and the government recently realized this is something they should invest in

Ϛѓăʑɏ βµԂԃϔ

I should reduce the usage of "ah" in h-bar... coz, I'll have to say it everytime when someone opens their physical mouth :D

user54412

@ϚѓăʑɏβµԂԃϔ Ah yes, gravitational waves - India's getting a piece of that soon I believe

Ϛѓăʑɏ βµԂԃϔ

@ChrisWhite Reserve a ticket for me... I'll catch-up tmrw...

@ManishEarth: Anyone in India involved in this grav. waves detecting scheme..?

(I thought ~~they're~~ (we're) interested only in Astrology...)

@ChrisWhite: You involved in nanograv...? (the collaboration has undergrads, students, grads and prof. too... Right?)

ManishEarth

@ChrisWhite LIGO?

Ϛѓăʑɏ βµԂԃϔ

07:14

@ManishEarth nanograv..!

ManishEarth

Ah, Wikipedia lists LIGO-INDIA

user54412

@ϚѓăʑɏβµԂԃϔ nope, I'm not involved

user54412

@ManishEarth yep, LIGO wants to give one of their detectors to some other part of the world

user54412

makes for better triangulation

ManishEarth

Huh, I thought it was going to be Japan

user54412

07:15

and I believe India stepped up for that task (after Australia opted out)

Ϛѓăʑɏ βµԂԃϔ

@ManishEarth Don't worry... Not for us....

ManishEarth

hmm

@ϚѓăʑɏβµԂԃϔ ???

user54412

hmmm, well, I guess these things can change

ManishEarth

@ϚѓăʑɏβµԂԃϔ Nobody I know personally. But I do know a lot of HEPhysicists

Ϛѓăʑɏ βµԂԃϔ

@ManishEarth We're busy with politics, astrology, cricket and Pak-China debates...

user54412

07:17

the square kilometer array was a European project that was choosing between Australia and South Africa, and in the end they decided to build half the array in each country o.O

ManishEarth

ha :p

Ϛѓăʑɏ βµԂԃϔ

@ManishEarth o.O

user54412

Maybe India and Japan can each have half an interferometer - one arm each :P

ManishEarth

@ChrisWhite Why not just pepper the world with radio telescopes? That would improve resolution a LOT

@ChrisWhite that would be HUGE :P

user54412

well, LOFAR did that on the scale of Europe

user54412

07:18

they're just starting to acquire science now

user54412

and beyond a continent, there isn't much resolution to be gained - after all, only half the earth is facing a source at any given time

ManishEarth

@ChrisWhite Wouldn't collaboration with just a couple of telescopes elsewhere improve resolution a lot?

For example, LOFAR+VLA

Or even LOFAR+3 telescopes from the VLA

user54412

@ManishEarth mmm, I suspect they're at different enough frequencies

user54412

though to be fair I don't fully understand the black magic of radio astronomy

ManishEarth

@ChrisWhite Of course, but Europe only takes up a quarter of the Earth

@ChrisWhite ah makes sense

user54412

07:20

well, in their minds they take up a bit more ;)

ManishEarth

lol

user54412

there is an issue of having power but not being near a city

ManishEarth

hm

user54412

it's actually an interesting calculation to work through

user54412

these observatories need lots of electricity, mostly to operate their computers

user54412

07:22

a lot of these plans fall through because you just can't feasibly build a power plant in the middle of nowhere

ManishEarth

yeah

user54412

solar is out, because you need power at night

user54412

wind is unreliable

Ϛѓăʑɏ βµԂԃϔ

@ManishEarth A lot of power shutdowns... wouldn't China give a few MWs for us - having completed the 3 Gorges project..! -_-

user54412

Native American name controversy

The Native American name controversy is an ongoing dispute about the changing terminology used to refer to the indigenous peoples of the Americas and broad subsets of these peoples, such as those sharing certain cultures and languages by which more discrete groups identify themselves (e.g., "Algonquin-speaking peoples," "Pueblo-dwelling peoples"). Many English exonyms have been used to refer to the indigenous peoples of what is now known as the Americas, who were resident when European colonists arrived in the 15th and 16th centuries. Some of these names were based on French, Spanish, or ...
