« first day (1732 days earlier)   

12:18 AM
is...is it you
 
yes :(
 
I got into a bit of pickle while trying to 100% GTA5
I just hit the stream button
 
link?
 
well I got rekt
time to play TES
@FenderLesPaul Skyrim or Oblivion?
or maybe Borderlands
 
Oblivion!
nostalgia trip
 
12:25 AM
aight that's what I've been streaming for the last few nights
 
omg that music
 
no static?
 
just sent me back 5 yars
years*
no static yep
 
cool, I figured out the mic
 
ahh such nostalgia
 
12:26 AM
Ooh, that's loud for me...I have to turn down the master
 
at one point I had ~120% reflect damage
it was so much fun lmfao
 
"A cosmic ray striking the Earth is not some random act of the gods that can have any imaginable consequence whatsoever."...Zeus will strike you down for this insolence, @ChrisWhite!
 
how's the stream quality?
 
it's fine
are you doing dark brotherhood?
 
yes
 
12:28 AM
sweet
 
that's why I'm in this town
 
that's my favorite quest line in the game
 
But I'm gonna do knights of the nine now
*start
 
mmk
sounds good
 
well shit where do I go
I prayed at a shrine of Dibella
oh EACH of the 9
too much work!
ah, Bruma is the location of the next TG and DB quests
whoops wrong city!
Bruma is far off...
 
12:32 AM
god damn you're making me want to go back to nyc and grab my desktop so I can play my old oblivion saves haha
 
oh god what is this ring!?
warning: bewbs
 
LOL he just dropped her to the ground in one hit
 
should I leave the ring of burden there?
 
yeah
leave it
 
it has NO use?
thief stone?
what is this?
 
12:43 AM
isn't it a rune?
increases your sneak or pickpocket or something for a day or so
if I recall
 
I left the ring of burden on a thief
I will never get it back
that OK?
 
yeah I never found a good use for it
 
ugh that distant terrain is ugly as hell
 
yeah draw distance isn't great in this game
 
I double checked to make sure I was maxxed out
bruma at last!
 
12:49 AM
funny enough I had it on the xbox 360 when it first came out in 2006 and played that for like a few years; a couple of months ago I popped it in again and jesus christ it was soooooo ugly
PC version is so much better which says more about the 360 version than anything else
 
well I have everything but AA maxxed out and the game is pretty ugly
 
granted it was 2006 but still
there were a few mods that made it look somewhat better
 
yeah
those are all shit for optimization so they'll kill my system
 
that dude's mouth is way too huge to be real
 
so on the mod front
I have a UI mod
male face textures and muscle mod
female booty mod
arrow damage buff (archery is still useless)
and the unofficial patches
 
12:52 AM
ah
yeah I only used archery when sneaking
to get the extra sneak damage
otherwise I just stuck to spells and melee
 
alright I need to find the TG fence
any tips?
 
I really can't recall unfortunately
 
you mind googling while I look for a shop?
 
the "stage an accident" part?
 
that's my DB quest
 
12:54 AM
oh
you need to find thieves guild fence in bruma?
 
I need to find the fence to sell some stolen stuff to advance in TG
@FenderLesPaul he is here, right?
 
yeah ongar
Because of his current profession, Ongar lives a quiet and discreet existence in the snowy town of Bruma. Retirement or not, old habits die hard, and he still goes to sleep early in the morning, at 6am. After waking up at noon he immediately ventures outside for a quick two-hour breakfast at his favorite inn, Olav's Tap and Tack. At 2pm he heads back home and wanders around until 6pm when it is time to visit the inn once again.
Here, he will spend a whopping twelve hours in the company of innkeeper Olav and the many Nord regulars.
 
found him!
thanks
 
should I sell this varla stone I stole?
 
12:58 AM
yeah it doesn't have much crafting use iirc
 
hmm the TG quest did not update
wait...how do you tell if an item is "stolen"
 
isnt it usually like red labeled?
 
tfw colorblind
ah there's a little red hand
there we go!
oh fuck me I have to wait till 8
@FenderLesPaul wanna Skype?
 
still 4 hours in-game
:/
forgot you can't wait while trespassing

1:16 AM
@Slereah thx again for this ref, just skimmed it, neat stuff. there does not seem to be a lot of standout consensus on almost anything. the lack of consensus is somewhat striking. there are some oddities. eg #4 only 20% said "bohrs view of QM is correct" but on #12, copenhagen interpretation got the solid majority at 42%. these two results seem somewhat inconsistent/ self-contradictory (unsurprisingly as polls often are). #4, "we'll have to wait and see" got a striking 30%!
#12 is stunning to me that debroglie-bohm got 0%... ouch! anything in/ near this area therefore would seem to be subject to a very uphill battle to say the least. to say the worst, its completely dead to active/ practicing modern scientists!
@DanielSank just think of it as long-form chatting which you seem to have no reservations about whatsoever & youll do just fine, you could make up objections :) ... anyway if you really are serious about influencing the next generation of scientists, what could be a better (cyber-) soapbox? eg do you ever read aaronson blog? great/ very lively at times stuff! also google blogs are making intl waves/ news headlines this summer with deep dreaming experiments!
@KyleKanos is the blog still published? how can one actually be bad at blogging, was not even aware that was possible! it just takes a lot of patience & "delayed gratification" sometimes... :|
 
@vzn I believe it's the thing linked in Kyle's profile
 
vzn
1:33 AM
@ACuriousMind ha ok yeah saw that once... didnt take it as "totally representative" lol... motivation & not writing topics can often be the bigger challenge with blogs. :|
 
2:05 AM
@ACuriousMind wanna join the black hole Skype call?
 
@vzn Well it's still on the internet: fortraninacworld.blogspot.com
But I've not updated in it for ~2 years
 
@0celo7 Not now
@KyleKanos I must say I kinda like the name
 
I came up with it after discussing Fortran vs C with a classmate
 
@0celo7 page 7 of the pdf: hartmanhep.net/topics2015/2-bhthermo.pdf
exercise titled "black hole collisions"
it's the non-spinning case but can be easily generalized to spinning case it's just a few more lines of calculation
 
obe
2:40 AM
@0celo7 can I join the skype call?
 
sigh took an algebra test online (for freelance work stuffs) and got 4.9/5 which put me at 2nd place out of ~700 people
 
algebra is hardcore Kyle
 
2:53 AM
@KyleKanos you should join the call
 
I'm about to head to bed :/
 
d'awww
:(
 
 
1 hour later…
3:56 AM
@0celo7 btw idk if you have any interest in condensed matter but if you ever wanna work through Altland and Simons "Condensed Matter Field Theory" let me know; it's something I've been meaning to undertake
 
@FenderLesPaul never heard of it :(
I've never heard of that book, not CM
@FenderLesPaul and just to show you it's possible...the pussy posse on a Mac
note I do have to letterbox because the 2k textures are very intensive and I like 60fps
 
5:02 AM
@DanielSank only certain parts of the help center can be customized. But the procedure is post a suggestion on meta, and if a consensus emerges in favor and it's in one of the editable sections, a mod will make the change.

@vzn How does one get attention for one's blog?

Q: Should we indicate the use of \renewcommand in the help center?

DanielSankWhen writing quantum mechanics answers I typically start with something like this at the top: $\renewcommand{ket}[1]{\left| #1 \right\rangle}$ Using a custom macro like this means that I can type \ket{\Psi} instead of \left| \Psi \right\rangle when I want to indicate a quantum state. This has s...

Hola fellow scientists... Quick question! answering one of my reader's question and stuck at this scenario - When I am free falling towards a gravity source, does the gravity gradient make me feel the gravity itself? I know that gravity cannot be felt. But what if the gravity get stronger as I fall? Will I feel the acceleration without any external forces other than gravity? Need an explanation based on newtonian physics and relativity as well.
 
9:28 AM
@KarthikeyanKC If you are big enough, you'll definitely feel the gravity as a tidal force. Who told you that the gravity cannot be felt
 
Well, if you eliminate all the forces, I mean like in a continuous free fall. We can't feel gravity, can we?
 
@KarthikeyanKC assume that you are the thousand-mile man
falling freely into the earth
that man would certainly feel the gravity
notice that the gravity is proportional to $1/r^2$ which means that he feels a strech as he falls down
 
We feel gravity due to the external forces acting on us. The drag. What about in vacuum? Will it be the same?
 
@KarthikeyanKC of course it will be the same situation for poor 1000 mile man
the gravity is a central force
eg when he falls sides ways the gravity will try to squeeze him
 
And why MathJax isn't working?
 
9:41 AM
@KarthikeyanKC you have to install the chatjax extension
 
Okie... Coming back to the topic, it would be helpful, if you could explain me further.
 
just draw a circle and arrows which are going radially inwards
wait lemme make a picture for you
 
No issues, I get it. What I don't get is, without any non gravitational forces acting on the body, how can one feel gravity? In a continuous free fall.
One feels gravity, because the ground exterts the force on the body. Even in atm the molecules provide a drag. But in vacuum, I don't get it! As far as I understand, I think can't feel it.
 
@KarthikeyanKC the circle is the earth
the arrows are not so well drawn vectors which represent the gravity
and the poor 1000 mile man is the thick line segment
do you see that the gravity is squeezing him as he falls towards the earth?
 
Yes, as I said earlier, I got it :) So the gradient would stretch in my earlier case, wouldn't it?
 
9:50 AM
@KarthikeyanKC yes
now gravity is indistinguishable locally from an accelerated reference frame.
however even if this is the case you can check for the presence of gravity/acc. ref. frame
by throwing a ball ;)
@KarthikeyanKC however if you want a more biological answer, as why we don't feel like as if we feel gravity
the answer is simple
 
@gonenc understood. So the term 'feel' is localized to the effects (tidal force) due to gravity. Gravity (a spacetime curvature) itself cannot be felt right?
 
we don't feel it because we so get used to it
@KarthikeyanKC well actually the curvature is the reason why you feel tidal force :)
 
Perhaps I shud've rephrased my question, eliminating the biological 'feel'.
 
in any case not-feeling gravity is not so realistic at least if you think theoretically
@KarthikeyanKC of course you don't feel the gravity of alpha centauri because it is so small but in theory you can make an experiment to detect its gravity
 
I think I could find a way to put my question now. Sorry I coudn't get to it before. Clearly understood the point. @gonenc, thank you. It was a weird notion from a theoretical standpoint, eliminating the biological factors and considering only a body in a geodesic in the curvature. I think I got it now. Thanks :)
 
10:00 AM
@KarthikeyanKC glad I could help :)
 
10:10 AM
I just wrote my first answer in ages :)
 
Congrats
 
@skullpatrol nice avatar
 
@skullpatrol It's been over 2 months!
And it made me go back to some stuff I had semi-forgotten, which is always nice :D
 
11:00 AM
@Danu what does it even mean?
 
@Danu is the proper english version this nuts?
 
@gonenc That does not have the same meaning but "deez" comes from "these", if that's what you're wondering
 
11:26 AM
Hello
 
 
1 hour later…
12:47 PM
Wait...skill patrol and skull patrol are two different users? My life is a lie!
 
:D
Nah, skull is my mobile username...
...when I'm on my Harley ;-)
 
I see :D
 
1:12 PM
@ACuriousMind Is video gaming a sport?
 
Huy
Generally, no.
 
@0celo7 That highly depends on your definition of "sport" ;)
 
sure it is
like chess
 
Huy
@skillpatrol: So playing Doodle Jump on my iPhone while I take the bus to work is sports?
 
@Huy it could be
 
Huy
1:15 PM
Could be implies it could also not be.
So it highly depends.
 
1 min ago, by ACuriousMind
@0celo7 That highly depends on your definition of "sport" ;)
 
Huy
That's not what you said.
 
chess was in the olympics
 
Huy
Nobody ever said chess isn't sports.
 
@FenderLesPaul Crap. It occurred to me that my reasoning last night was as follows: Each point in the null cone (the on in $M$) is path connected to the point $p$, by definition. Thus we can compose the paths to connect any two points in the null cone. However, the trivial curve $\gamma(t)=p$ is not in the interior and thus we may not implicitly use this curve in our composition.
@FenderLesPaul The proof of 12.2.1 requires that the interior of the null cone is connected. For that, I got nothing. Unless...is the light cone (in $T_pM$) isomorphic to the Minkowski one, since global topological properties do not matter locally? The Minkowski one is obviously connected...
I think "sports" has to include "athletes" and "physical exertion" in there somewhere.
(Playing LoL for 20 hours straight does not count as physical exertion.)
 
1:21 PM
Well, then you have defined sports to explicitly not be video games, so why ask the question?
 
Huy
@0celo7: LoL is too easy anyways, you should take a more difficult game as an example.
 
@ACuriousMind I was curious about your definition.
 
Meh, I don't care enough for sports, electronic or not, to try and find a sensible definition.
 
Sport (or sports) is all forms of usually competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing entertainment to participants, and in some cases, spectators. Usually the contest or game is between two sides, each attempting to exceed the other. Some sports allow a tie game; others provide tie-breaking methods, to ensure one winner and one loser. A number of such two-sided contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games...
There has been an increase in the application of the term "sport" to a wider set of non-physical challenges such as electronic sports, especially due to the large scale of participation and organised competition, but these are not widely recognised by mainstream sports organisations.
 
Huy
For a reason.
 
1:27 PM
the reason is that it is new pal
 
@skillpatrol Electronic sports are growing at such an immense speed that this is just a matter of time.
 
Huy
@skillpatrol: The reason is that it is a completely different kind of activity.
 
@alarge I agree.
A game is structured playing, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games). Key components of games are goals, rules, challenge, and interaction...
getting dangerously off-topic :-)
my apologies to the room
 
This room does not really have a notion of "off-topic", in my experience.
 
the math room certainly does
 
Huy
1:36 PM
:-(
 
Huy
@skillpatrol: What video games do you play?
 
none, regularly
 
Huy
Interesting.
 
@ACuriousMind I'm sure I could find something. ::goes to 4chan.org::
 
1:39 PM
@Huy you?
 
@0celo7 Standards of basic human decency are different from "off-topicness".
 
Huy
@skillpatrol: Several, regularly.
 
cool
 
@ACuriousMind Wow. Hurtful much?
 
Huy
Most recently Cities Skylines, probably the most fun I've had with a game in years.
 
1:41 PM
Anyone remembers where to find the exact solution for phi4 in 2+1D?
Can't seem to find it again
 
@0celo7 Okay, show me something that you think we'd call "off-topic" from 4chan that's not repulsive in some way.
 
Is there some fundamental reason why phi4 is solvable in 2+1 but not in 3+1?
 
Well I don't know if it's solvable in 3+1
but it is certainly solved in 2+1
 
@ACuriousMind The problem is that we don't have a notion of off-topicness here.
 
Just because lower dimensions are simpler to solve
 
1:44 PM
@0celo7 But you said you could find something...what were you thinking of?
 
@ACuriousMind That's for me to know.
Forget it.
 
@Slereah You're being classical again, aren't you?
 
@Slereah Derive it yourself.
@ACuriousMind What's wrong with being reasonable?
@Slereah Why is the interior of the light cone (the set of timelike vectors in the tangent space) a connected set?
 
@ACuriousMind : Quantum this time, actually
 
1:49 PM
@ACuriousMind Stop quoting a book you've never read :/
 
Trying to find some exactly solved QFT to do math on it
But damn Thirring model is hard to grasp
 
why read the book when the prof makes it into a movie
 
@0celo7 Why? It's a good quote.
 
there's a physicist called Shapiro
 
@Slereah I think there is a rigorous proof of triviality of $\phi^4$ in four dimensions, i.e. the theory inevitably renormalizes to a free theory. 3D should be fine, though.
 
1:53 PM
And I have a hard time taking him seriously
Because his name reminds me of youtube.com/watch?v=Q5hn8bhEpMY
 
@Slereah time delay?
 
The only exact solvable models in 4D I can find are SUSY models and my body is not yet ready for those
 
now how do I find this quote in Shankar...
@ACuriousMind OK, I can confirm that quote is in the book.
@Slereah I would appreciate it if you could help me with the light cone thing
 
Not sure
If it was the light cone in the manifold, it wouldn't be too hard to show it via like
path connectedness
I am not v. good at topology
 
2:21 PM
check this paper, maybe
It's a good compilation of spacetime topology stuff
