@dmckee I just edited some things in this answer of yours. physics.stackexchange.com/a/517557/127931 I would have proposed an edit if possible. I'm pretty sure that's what you meant to say but please feel free to fix it if not.

Wait I can't remember, do you get notified when someone edits your post?

@ACuriousMind only because someone 40ish years ago said we should use Cobol & it was so embedded deeply since that we can rid ourselves of it

@DanielSank i don't know if this counts as cool, but i just finished a presentation for school on how perspective shifts affect the perceived morality of retellings of beowulf over time so i could wax on about that :)

bit overly specific though, haha.

@JMac You do get notified. I was slightly embarrassed by the shear number of things there were for you to fix, but I thought your work was spot on.

@heather That sounds interesting.

Tell more?

so basically, i looked at four works: beowulf, myths and romances of the middle ages (which contains the first 'retelling' as opposed to just a translation of beowulf), grendel (probably the most famous retelling), and the mere wife (probably the most recent retelling) and looked at how perspective shifts: the first two are in third person, the third is in first person, and the fourth switches between several first person and first person plural narratives

they also move from having the most clearly delineated monsters and heroes to the least clearly delineated monsters and heroes

so it's along those lines. it's nothing new: other researchers have noticed that readers tend to question what's going on in a story more when it's in first person (think, e.g., unreliable narrator), so that tends to gray things out more.

myths tend to be told in third person because they have very specific perspectives: a lesson to be taught about history or how to act.

thus you get this trend from a third person, morally black and white story in beowulf to a morally gray story by the fourth retelling, which is in a primarily first person form.

here's another example about how perspective affects things: it makes 'bad' characters more bearable if it's in first person. think of humbert humbert in lolita.

so grendel, the third retelling i looked at, kind of takes this approach: it makes grendel seem okay because it portrays mankind as equally evil.

there's this one really pointed line where the scyldings call the government 'monstrous' as grendel is off to the side listening in - might as well wave a giant sign saying, look, look! the monster isn't the only monster!

the mere wife is really interesting inasmuch as it doesn't portray everyone as equally evil, but as equally good, in a way.

feel free to ask me questions about it - sorry for the text wall.

Hi

Does nuclear fusion also emit harmful radiation like nuclear fission does?

@Paṇḍyā yes it does, but it doesn't produce the dangerous nuclear waste that fission produces. It's the long term storage of that waste that is the big problem with fission and that problem doesn't exist for fusion.

@JohnRennie Thanks for the reply. I want bit more elaboration to study. Can you refer me an article or anyother source for radiation comparison between fission and fusion.

or would it be fine to ask a question on site?

@Paṇḍyā I don't know of an article offhand, but it should be an easy Google.

keydifferences.com/…

@Paṇḍyā^

@skullpatrol It doesn't talk anything about radiation.

@JohnRennie ok

@Paṇḍyā the fission process produces gamma radiation from the moving charges and also highly energetic neutrons. That is the only primary radiation.

@JohnRennie Hmm.. I see it would be emitted from sun also and protected by layer of earth atmosphere. Btw, I found fusion is far more controllable than fission; which is another good point.

@Paṇḍyā However those high energy neutrons can collide with atoms in the surrounding of the reactor, and it can cause them to become radioactive. This is the induced or secondary radioactivity.

But the induced radioactivity is mainly short lived and not very dangerous so it is easy to deal with. The problem with fission is that it produces long lived an very dangerous waste that has to be stored for thousands of years.

Got it. Thanks.

The only problem with fusion is that no-one has been able to make it work yet :-)

The prime difficulty for having nuclear fusion is a demand of very high energy input (temperature or velocity) I think.

@JohnRennie Look in the sky

there's a big fusion

@Slereah not all that controllable though ...

Maybe that's something to look into

Thermostat for the sun

does "god" have a thermostat for the sun, and if so does that mean blackholes are the deep freeze?

also a good idea against global warming

true

@Paṇḍyā try this?

@Loong^

hey, so in experiments like the YDSE, when light waves interfere ON the screen, we either see a bright spot or a dark spot right?

but, they are interfering ON the screen tho, not in our eyes so why do we see this?

@JohnRennie waruuup

Can anyone provide any references to modeling the movement of mobile devices using differential equations?

anyone alive?

nvm, solved my python problem

hey guys. A very stupid question! for scalar field with interaction term "g * \phi", does this interaction term play any role?! I couldn't draw a good feynman graph besides a "dot" haha

$$ \nabla^2 = \left[ \dfrac{1}{r^2} \dfrac{\partial }{\partial r} r^2 \dfrac{\partial }{\partial r} + \dfrac{1}{r^2 \sin \theta} \dfrac{\partial}{\partial \theta} \sin \theta \dfrac{\partial}{\partial \theta} + \dfrac{1}{r^2 \sin^2 \theta} \dfrac{\partial^2}{\partial \phi^2} \right] $$

@AbhasKumarSinha hello bro ,whatsapp.

@yuvrajsingh cool, you?

good.

i am in train going home @AbhasKumarSinha

any experienced writers around?

experienced how?

a coauthor wrote "we have found in our analytical analysis that..." and I'd like to get rid of that ugly repetition

cuz i write stupid docs for work all the time

i'd just remove the "analytical"

but I don't see any good synonyms for either

@KyleKanos there is also a numerical part of the research

okay, what about inserting words to at least distance it?

e.g., "...the analytical portion of this analysis..."

that's a thought

or separate the numerical and analytical portions into separate papers. increase your h-number or something

Would there be a good replacement for "analysis"? I can't think of one, but I have a feeling that there should be.

@KyleKanos oh, no, one paper on this project is enough, thanks =)

@JMac investigation is my first though

*thought

@JMac you'd hope for one, right?

@KyleKanos it's rather pompous, particularly for how deep into the manuscript this appears

what about using "results" instead of analysis?

or something similar?

fuck it

"analytical theory" it is

thanks, guys =)

@EmilioPisanty "we have found in our theoretical analysis" maybe?

@tpg2114 I guess that could work?

it's a long paper and my standards are not that perfectionist, though

it works as is, without being explicitly horrifying, and that's all I need :-|

Hah, yeah, I feel you on that one

I have a random question about setting up/filling out PDF forms electronically. Anyone have experience in this area?

I've filled out plenty, but not set them up

I do have Acrobat Pro right next to me so I can play with it if it's something that needs a second set of eyes

@tpg2114 I have a form that needs to be filled out/signed by various people (but it is all on the same sheet of paper). All but 1 are available to do it by hand. So for this other person I need to send them a scanned copy of this form to fill out. I didn't know if there was anything I need to do on my end to make it easier for them to do that.

Right now I just have a PDF of the scanned form

Sounds like a thesis/graduation form or something ;) I actually just mailed a matryoshka set of pre-paid flat-rate envelopes so the 4 remote signers could pass it on to the next and it would end up back at me...

Adobe has some "Add a signature" thing where you pick a cheesy font, type your name, and specify where it goes. I don't recall if the free Reader has that, or only Pro

@tpg2114 Haha it sounds like that, but it is not. That does sound like an idea... The form is due December 15th I believe

So that could be enough time

Cool, thanks

I could just ask them if I can fill it out and sign it for them I suppose haha

I don't think there's anything you need to do to make it easier, provided they are using Adobe

I think the free reader, under "Tools", has a "Fill & Sign" option

And if you click that, and then click on "Sign", you can type in your name and choose your cheesy font and then paste it anywhere

I've also taken scans of my signature, set the background to transparent, and pasted those into PDFs before also... I don't see anything simpler in the PDF-making stage

Ok sounds good. I think I'll send over the scanned PDF and tell them to reach out to me if they have any troubles.

*Adobe on Windows... no idea what features exist on Mac/Linux

Thanks for the help

My guess? They'll print, sign, scan, send back

In which case -- make sure your scan is uber-high quality

As many DPI as is reasonable

Ah yeah I guess I hadn't considered that option haha

Path of least resistance and all.... or, as I like to call it, path of optimal laziness.
