So I'm an applied math major and people here seem to suggest to build up a programming portfolio to increase my job prospects.
But what the fuck do you guys actually make for in a portfolio? The only programming I've learned is how to use Python and MATLAB for computations, modelling and solving differential equations. I don't have a clue how to actually develop an application. I don't have any good ideas on what to develop. Can someone help me?

not really! a portfolio implies you make interesting small-ish projects, and that means you need to konw what to do. making small projects and posting them on github is a good idea
>>
>>8208583
If you want to get good at programming you need to stop with matlab at once and start writing some actual code.
If you want to remain in the domain of math start looking at for instance a generalized genetic algorithm solver which uses abstractions that make it agnostic to genetic representation, fitness evaluation and reproduction strategy. It's a tall order, but it forces you to think a lot about what the correct abstractions are, and how to generalize

That's fucking interesting man, what language do you suggest I learn? Right now I'm trying out Haskell for shits 'n giggles and I kinda like it.
And why does everyone hate Matlab? It's faster than Python.

Physics open discussion via Google Hangout TONIGHT at 11:59 EST
Hosted on the Youtube channel DraftScience. You can watch the live Youtube video stream+side chatbox, or you can join the Google Hangout and cam up+speak over microphone by clicking the link in the video stream's description box. I will post a link to both the video stream and the Google Hangout at 12 AM EST. You need a Google+ account to join the Google Hangout, but not to watch the stream.

Would you agree that "life" (distinct from "existence" which comprises matter that is not conscious/doesn't experience) is simply a succession of uninterrupted experience? And said experience is simply what the entire universe is doing at that particular place filtered through the prism of one's senses and ego? This whole process is changing, warping, chasing entropy at every passing smallest unit of time like an incredibly complicated rapid crashing through its own contours and is only given context, meaning, and a semblance of regularity because of the existence of observers?
For example, before you were born it wasn't waiting in line for 14 billion years-it was just "POOF" you exist. We know that it took many, many, MANY years for Earth to form (and many more for it to become home to sentient life) but it doesn't matter because if nothing is being perceived then that time is perceived to pass by instantaneously. It's an UNINTERRUPTED succession of conscious experience because the absence of the experience is skipped like how two separate audio/video files in an editing program get spliced together-there's simply nothing going on in between.
When you die it will be like before you were born-POOF! Experiencing consciousness as something else. My best guess is as another organism on Earth. It makes not sense that when a fly dies it dies for all eternity-but the popular conception of death for humans is that we DO die for eternity-completely leaving unaccounted for how in the hell we got here in the first place.
And even when Earth becomes unable to support life in 500 million years it won't even matter. It's of no real concern to observers because even if it takes trillions upon trillions upon trillions of years for conscious life to arise again it will necessarily and inexorably be perceived as gapless. There is no waiting because there is no one to wait.

I'm using strang's introduction to linear algebra and this book is extremely hard. like, I've gotten to page 35 in 2 days and I think i understood about half the stuff i read, none of the challenge problems. It doesn't help that there are no solutions for the problem sets...
Is this book supposed to be for first time learners? What did you guys use? Should I just bite the bullet and get through this book or opt for something more learners friendly?

(45241/9)+-(1176407/90)x+(308340161/22680)x^2-(5330767/720)x^3+(1262363/540)x^4-(79561/180)x^5+(53129/1080)x^6-(237/80)x^7+(421/5670)x^8
is one solution. For x=1, you get the first number in the series. For x=2, you get the second and so on. The ninth tells us that X = -(8381/9)

As a math fag, should I be concern that I know nothing about tensor calculus? Should I care about them in pure math? What's a good book on tensors?

You know that pure math is a big field? This question is basically unanswerable. You'll probably never use it for math, and if you need it then you'll know.

>>8206924
Tensor calculus is pretty much where linear algebra and vector calculus become one subject.

I made the mistake of eating two burgers and started feeling uncomfortable. I'd had some wine beforehand, so that may have contributed.
I began breathing rapidly and shallowly, and because of this, I was afraid I would vomit.
Breath control didn't work. My skin felt like cotton wool, which is how it usually feels on the rare occasion when I can't get enough air into my blood (high altitude, etc.)
But then I remembered the "mammalian dive reflex," which lowers heart rate in cold water.
I rubbed my face with an icecube until my breathing and heart rate slowed.
Placebo is possible, but this is digestion. It's about as concrete as it gets. My stomach is just as stuffed as it was before.
Why did this happen in the first place, and why did a cold face make it subside?

Why do we assume that the laws of nature is the same everywhere in the universe? Is it simply because we want deterministic models or is there more to it than that?

What did they mean by this? What PRACTICAL limits does the scientific method have in principle, beside certain experiments being too hard to perform? Is there another method that fills in the gaps?

> Scientific method has limits
It's not the fact that it has limits, It's the fact that scientific method is the most reliable and logical method for finding out answers, which is why it's the only option.

>Is there another method that fills in the gaps?
no. If our current "understanding" of the world has shown one thing, it's that humans are notoriously bad at reasoning about how the world works in absence of any evidence in one direction or the other.
