Plan on double majoring in accounting and finance. What things should I specifically be able to code? The only things i know is CS is a meme and cant be trusted and a bunch of business analysts program. algorithms. I also am aware a bunch of people from wall street majored in physics and mathematics.

Honestly, as a finance major and software engineering minor, all I use is VB, and Visio. There are so many CS and SE majors that are much better at programming than I am, so if I understand a system that I need, I'll outsource the programming to another department.
>>
>>8663286
I see. Do you rec I do any coding in my free time on my own at all? Or just take a few coding classes with my majors? Should I minor in Software Engineering too instead of taking CS classes?
>>
>>8663297
Since I don't think programming skills will be obsolete anytime soon, I would recommend it.

I don't know how strong your uni SE program is, but SE is traditionally more applied knowledge than CS theoretical knowledge. Anyways, my school's SE program is ranked in the top 15 nationally, so I knew my extra time and money was being well utilized.

Just crushed a short semester on CALC ii, what should I expect from CALC III? Is it so much more difficult or is akin to Calc ii where it feels like were just adding more to our arsenal? Anythings to watch out for? Recommended reading/watching?

Analytic geometry is trivial and pretty tedious. I'd recommend finding a non-brainlet source and keep it as a reference guide for when you need it in the future.

That's what I do.

What's the motivation for a non mathematician to learn about complex numbers? What about infinite series?
11 posts and 4 images submitted.
>>
>>8663089
Complex numbers are extremely useful for modelling trigonometric functions due to De Moivre's theorem, so it is good for anyone who works with things that act like waves, such as physicists who work with waves or electricians who work with electricity.

Infinite series are a (usually) good way to turn a messy function in to something a little more clean. From there, you can sometimes find the derivative or integral of said function in certain conditions. Knowing if the series converges or diverges is important for knowing the radius of convergence, i.e. when it's okay to actually use the series to represent your function. Computer scientists and engineers may use just a few of the first terms of the series to approximate the function in that case (some engineer's go as far as approximating sin x as x on the interval [-1,1]).
>>
>>8663089
Those concepts are really trivial low-level math and therefore have applications everywhere. Just ask an engineer, but here is a warning:

Engineers are a weird bunch. Instead of writing the square root of -1 as 'i' they decided to write it as 'j' because they were not comfortable with a dick-shaped letter as short as i, given that the dicks they take up the ass are longer, like j. That said, those are still the complex numbers. Not some other weird set they discovered. The only things engineers discover are new cocks up their ass.

Is Linear Algebra THE way to go if you want to do a PhD but don't want to be in academia afterwards?

Linear algebra has a wide variety of applications in easily applied fields.

Is there any other field in math that is also easily applicable to the real world?

I want to keep my door open to work in R&D at all kinds of firms so I want to take a Math focused PhD but I don't want to do it in Prob&Stats.

-----------------------

Sidenote: I'm not in the US. From what I've seen about 2/5 of R&D employees and 100% of R&D employees doing R&D have a Ph.D so I NEED a Ph.D. Also for job security and climbing the corporate ladder later on.

Why do people even think humans have a future in space travel when we can never break the speed of light?

Most of the habitable planets are hundreds or thousands of light years away.

Even if you consider sending generation sleeper ships where people just hibernate for hundreds or thousands of years till they reach the destination, there are probably several different things that can go wrong with the ship in the interim such as engine failure, hibernation pod failure, micrometeorite damage, rogue black holes etc.

Just memes alone are not going to cut it.

TFW the planet is already inhabited by humans who had superiod tech and started 500 years after your generation sleeper ships.

You don't understand relativity. Look up time dilation.

It is (theoretically) perfectly possible to travel billions of light years in what would appear to you as one day. You just need to get really close to the speed of light (relatively to your starting point & destination).

this topic has always interested me
if the person in a spaceship going nearly lightspeed sees themself as going faster than lightspeed, who's to say that their perspective is wrong and the perspective of the Earth is right? maybe they really are going faster than lightspeed but only in their own frame of reference

/hairgen/ - ITT we try to solve male pattern baldness. Anatomy students welcome!

Male pattern baldness affects every man. We must stop this epidemic and restore our pride. More than half of you on this board are on propecia - so why not actually do something and use those brains of yours to solve this enigma?

Here's some link with background and current research:

What is DHT?
>http://www.bodybuilding.com/fun/reform8.htm


OP here I have a few directions to take us. Since it has been found that high DHT levels cause DHT sensitive follicles to fall out and shrink. Do we regulate DHT levels? Do we find ways to metabolize it faster? Do we counteract it with estrogen? Propecia is not a solution to the problem because it causes other problems. Do we find a way to make more DHT receptors so as to "up/down regulate" hormone activity and sensitivity? Does anyone know of any enzyme that breaks down DHT?

Because I study pure mathematics lol.

Red pill me on longevity and reversing ageing. From what I've read, listened and watched (a lot) it seems perfectly plausible that we could do this in 20 to 25 years. I mean, the science behind it seems sound and we just reversed aging in mice last year.

But then there are a lot of people who are saying that it's not possible and even if it is possible, it will get banned or only the elites will get it or it will only become available 100 years from now.

What's the reality of this all?

I think it's possible and will happen, but just in a long time. Remember drug idea to market takes 20 or 30 years, I don't think we'll see legit extension medicine until maybe 50 to 80 years, probably even longer. Think of all the long term studies that will be needed.

I also don't think it'll be restricted to the elite. With Internet and democracy we've had the most equality than any other time in history, and if you want to make a lot of money, you lower the price and expand the market, which someone will definitely do.

>Remember drug idea to market takes 20 or 30 years

Maybe here in the West. But then again, would you go to China for treatments against aging? I won't even eat their food when I travel there.

We can't even get to mars. You want reverse aging in 20-25 years? Try 70-80 years at the earliest.

Janthinobacterium lividum produces a compound that can kill of chytrid fungus (which is what is causing worldwide amphibian extinctions). People are now going around dousing frogs in baths of the bacterium and it seems to help them survive.

Thiomargarita is a bacteria that is so big it can be seen with the naked eye. Another gigantic bacterium is Epulopiscium, which is found only in the guts of some species of Surgeonfish.

That 'wet earth smell' that you sometimes notice after a rain is actually a chemical called geosmin produced by a very abundant genus of soil bacterium called Streptomyces.
>>
>>8662782
Also, some marine amoebae harbor giant viruses that are larger than many bacteria. Some of these viruses' capsids are coated with phospholipids, which some ppl think is meant to trick the amoeba into thinking it's a bacterial cell and eating it.

actuary isn't a particularly difficult job, but it requires a particular route through school and some extra exams. it pays well, too.
that said, i've never met an actuary that likes it. every single person i've talked to hates the job. almost unanimously though, i hear "but the pay is good i guess." even at a career fair, the actuary said "i wish i would have done something else, i hate this job, but the money is alright."
