Ignorance is bliss
Imagine if you all of a sudden could have a choice - do you want to learn all mathematical knowledge that will ever be discovered by humanity?
I would say no without any hesitation. I hold mathematics to be the primary human accomplishment without parallel, a body of knowledge that can be so succinct yet expressive in describing the nature of the universe that it is almost spiritual, a gift from the divine.
If you were to understand it all, everything would be subsumed by it. Absolutely everything, because so far it seems like everything can be described by it, and I'd wager it's safe to assume everything will be
Imagine if you knew everything. You would feel trapped into the box that is reality and you would just think "yep there's literally nothing more for us to discover that is as significant as what I now know, there's nothing left..." Holy shit I want to commit suicide at the thought of this. I've been getting scared lately that I might end up doing so out of fear
Am I going insane?

The truth is that everyone is ignorant. You must explore your own ignorance before you can move forward.
You can only ever move forward.

>>8325779
No. Not because I want to be ignorant but because I couldn't give 2 fucks about math that I will never use outside of memes.

Become a physician.
There's this passage in this book describing the effects of a relativistic kill vehicle:
>Virginia was more than three hundred kilometers away when the light burst toward her. Every nerve ending in her body began to record a strange, prickling sensation -- the sheer pressure of photons trying to push her backward. No shadows were cast anywhere in the tower, so bright was the glare. It pierced walls, ceramic beams, notepads, and people
My question is: is this passage scientifically accurate, and if so, how much light would be needed for it to shine through solid objects and how would you figure that out? Basically, how much light (I'm not sure which specific measurement to use) would it take to make an object of a specific density and mass translucent?

He answered the question. Since it's not scientifically accurate, the rest of the question following "and if so" is ignored.

Sup guys. Does anyone know a way to compute the series
[math] \sum_{0}^{\infty} \frac{(-1)^{k}}{(2k+1)^{n+1}} [/math]
for any natural number n? I tried to separate it in even and odd ks, but it doesn't seem to help much. I'm looking for a closed way to write it, using the Zeta function.

It's a Taylor series for a very well known function.

Throughout your school career, how did you view people who were really bad at math? The kind of kid that made the rest of the class facepalm or sigh in frustration whenever they asked a question that was so basic it hurt. Have you ever met any kids like that who were legitimately smart but for some reason were god awful at math?

Is this picture of spacetime a lie? How would this "local spacetime" even work for objects that are above or below earth?

Isnt this a much better visualisation of what spacetime actually is?
>>
>>8325287
Yeah. The first picture is just an analogy because brainlets can't into curved 3-dimensional space.
>>
>>8325285
It's, qualitatively only, visualizing the curvature of a particular two-dimensional slice of spacetime. It's easy to visualize the curvature of 2D manifolds, because you can embed them as a curved surface in space by adding an extra dimension.
However, curvature doesn't actually require the existence of extra dimension(s) to be warped in; it's just a propriety of the way points connect to each other. Spacetime curvature, in relativity, is specified only in terms of the distances between points and the angles between lines; it's not really treated as being bent "in" any particular direction.
Also, that picture leaves out that time, too, is also bent, not merely space. This leads to the classic confusion about what pulls stuff "down" the "rubber sheet" in the first place, which is entirely a symptom of this rather misleading visualization.
So yes, if you take that picture literally, it's very misleading.

The wire on the right that connects to the glass tube. How exactly does it connect to the tube? Does it go inside the tube, or does it wrap around the tube? Is it a continuation of the wire on the left side that coils around the tube?
Can you show us another photo that shows a close-up of the tube? Preferably a side view. I want to see what the wire on the right connects to.

When trying to teach a high level physics idea makes sense to abstract away the gritty bits. Or something else similar

Weight is acceleration due to gravity. Forces cause acceleration. Then isn't gravity is a force?

CALLING ALL CHEMFAGS, RADIATIONFAGS
My professor asked me to write a 1 page response to the following article:
http://scitation.aip.org/content/aip/magazine/physicstoday/article/69/1/10.1063/PT.3.3037
Basically, discusses the fear mongering surrounding low dose radiation and points out the evidence for fearing the dangers of low dose radiation is lacking. It discusses the validity of the LNT model, which believes in a linear relationship between radiation doses. So if lots of radiation is bad for your, a little bit of radiation is also bad, just not so much, but still bad.
The article argues though that low dose radiation has no effect and you should only worry at around 500 mGy, which is much less than your average x ray or cat scan.
What does /sci/ have to say about this?
Currently I'm reading up on LNT, comparing it with radiation hormeisis (low radiation is good) and Threshold model (low radiation can be ignored).
I personally feel inclined towards the Threshold model.

kek'd. Its just a writing assignment, I'm a chem undergrad, but I'd like to see what sort of sources /sci/ could pull up. But at the rate of this thread looks like I'll just have to push along.
Also just to clarify, if you give any sources, the only ones I can use are ebooks.
Though really I'd just like discussion on this for perspective.

I'm not gonna do your homework. Think about the topic yourself and write the one page report.
