How does a 1-year master’s degree in the UK compare to a 2-year master’s degree in the USA?

Is it too short?
Is it a business?
Is it a meme?

Not OP. In engi what's the difference between meng( included in 4 years as beng +1yr meng) and msc(separate)?
>>
>>9124611
Mainly that its a composite course; consequently rather that being first awarded a BSc, and then going on to your MSc, you will be awarded a single graded MEng. Hence the assessment is usually different, a separate MSc course can easily have a small project/dis focus, whereas MEng students typically have a large final year project. It may also require you to take more difficult modules in your third year, and have a different set of compulsory modules.

Now is the time I have to choose what to study. I want to study pure maths, since I've already read some books on pure maths and thoroughly enjoyed them. However, my father says that I should choose something more practical, like CS or engineering. How to convince him that pure math grads have more options even if they don't want to go into academia ( if this is even possible ). Any studies, links showing your evidence is very wanted.

Hello /sci
I am a coder in R and thinking to go for deep learning stuff. I realized that I am lacking knowledge of vectors, matrices and arrays. What is the fastest way to get into it? I don't need super skills, just an understanding what am I doing. Another problem, I was educated not in English and confused about terminology. If I need vectors then I need Linear Algebra, right? Do I totally need Calculus before I start? I've got some formal undergrad education in math but it was long time ago. I have basic understanding of derivatives, integrals, sets and everything, but very basic, to be honest. Right now I am refreshing limits on Khan Academy but it looks like a long way to go and I have only month or less to spend. I can just skip it and just memorize code and tricks but I feel much more confident knowing what I am doing.
Thanks

Hey Sci, I'm a business major, but I plan on going into Mortuary Science. I haven't taken a humanities course in a while, and I'm in a bit of a rough spot. Do any of you overly intelligent gents have a good way/study source?

Anatomy is an extremely in-depth field of study, and how to study it primarily focuses on your personal motivations. However, I recommend reading the introduction to 'Clinically Orientated Anatomy' for the very basics, and then some osteological texts depending on your chosen goals. Your program should include an A&P class, no?

Also, A&P is a science field, not humanities, so I'm not sure what you mean by that. If you're looking for advice on how to study English, you've come to the wrong place.

Haha, clearly I don't know what the hell I'm doing, but thanks dude. And I'm still working on my final semester of undergrad for a BSBA. Just taking the anatomy course to avoid it when I change schools. Taking psychology for the same reasons.

First year med student here. Anatomy sucks. Prepare to dedicate tons of time to it. And I mean, tons. Constant repetition is key, you won't remember dick otherwise. Learn, and understand, and then drill till the cows come home. Get whatever books your class recommends, but Netter's atlas is a must have. Good luck, my dude

Hello /sci/,

Today I'm going to show you a secret way of breaking your addiction to pornography. Even if you don't regularly watch pornography, that nagging sense at the back of your mind is sure to cause you problems.

First off, take a deep breath, and pay close attention to the position of your tongue. Do not bite your tongue or allow it to touch your teeth.

Now, when you view an explicit image (like on /gif/ for example), keep focused on the position of your tongue and do not allow it to touch your teeth. What do you notice?

fuck off you cunt.

>>
>>9123549
No no, this is not an "oral fixation fetish", I am telling people to take notice of things they might get distracted from unknowingly when they see explicit images.

I'm just trying to see if this is something that works.
>>
>>9123542
The explanation for why biting the tongue might be related to arousal is that seeing explicit images may somehow trigger a subconscious urge to inflict pain on oneself by biting on the tongue, then the mind knows that jerking off/sexual activity would allow that pain to end, thus causing arousal/sexual urges.

Where do I find replacement objective lenses for my microscope? The cats knocked it over and I broke my scan and low power lenses, but any search I do for objective lenses pulls up results more expensive than my microscope. I was really hoping to spend like fifteen bucks on a lens.

Do you really think all the math nerds on this board even know how to use a microscope?

But jokes aside although I haven't broken any microscope equipment or have had to replace anything on my babies yet I can't say for sure but try checking ebay. If I remeber anything from my undergrad years it's that whenever the PhD student broke equipment they would just order a new one or look for parts on ebay. Especially for somthing as common as an objective lens on a microscope microscope it shouldnt be too hard.

What kind do you got anon.

Also do you mind posting a picture of what you think is broken.

Contact the manufacturer and ask how much a replacement lens is.

Hey all. I took Linear Algebra last fall, but the ODE stuff was never cemented in me, nor did I practice enough. In fact, I forgot how to solve them by the middle of Spring 2017 semester.

So, before school starts back up in 2 weeks I want to practice my ODE's again. I picked up a practice book by Schaum (pic related) which is awesome. Tons of solved problems in case I get stuck, and quick introductions to each type of ODE.


My question however, is more on the "why". What exactly is a first order homogenous equation, and why does making the substitution of [math]y=vx[/math] or [math]v= \frac{y}{x}[/math] work?

Additionally,

For Exact first order differential equations, what is all this about [math]M(x,y)[/math] and [math]N(x,y)[/math]? I can solve these problems easily, but what's the deeper meaning behind these solutions and why do they work?

>homogeneous
Read the definition. Suppose that we have [math] f,g [/math] such that they are nth degree homogeneous and we have the differential equation

[math] f(x,y)dx + g(x,y)dy =0 [/math].

So consider the substitution y=ux, so dy = udx + xdu. We then get:
[math] f(x,ux)dx + g(x,ux)(udx + xdu) =0 [/math].

By the definition of nth degree homogeneous, this turns into
[math] x^nf(1,u)dx + x^ng(1,u)(udx + xdu) =0 [/math]. And you notice there is something you can cancel.

[math] f(1,u)dx + g(1,u)(udx + xdu) =0 [/math].

And now just rewrite it in a cute way.
[math] g(1,u)xdu = (f(1,u) - g(1,u)u)dx[/math].

And now even cuter.
[math] \frac{dx}{x} = \frac{g(1,u)du}{f(1,u) - g(1,u)u}[/math].

The left hand side is a function of x. The right hand side is a function of u. It just werks because it is separable. Maybe I did the algebra wrong but you get the idea. Homogeneous = we can cancel out x almost completely and get rid of all the complexity of the equation.

Gonna do a follow up on exact ones. Give me a min.
>>
>>9123481
>Exact.
Read the definition.

Anyways, exacts are now less about algebra and more about analysis. If you did calculus 3 then you know where this comes from and if not then I guess it is time you study vector fields. Anyways, even if you do not understand what I am about to say then at least I will be pointing you into the right direction.

Anyways, you know that if [math] F [/math] is a vector field then

[math]dF = F_x dx + F_y dy [/math]

And you also know that if F is a vector field then setting [math] F = C [/math] generates an implicit function in a dimension 1 smaller than the dimension F is defined in. But if [math] F = C [/math] then [math] dF = 0 [/math] which implies [math] F_x dx + F_y dy = 0 [/math]

So F as a generator of implicit functions is a solution to the differential equation it itself generates. However when you are given problems you are not given F. You are given M and N, but you hope in your heart of hearts that there exists some F such that [math] F_x = M, F_y = N [/math] because if that is the case then your differential equation is just the differential equation generated by some vector field so now all you need to do is find the vector field and then find the family of functions the vector field generates when it is "converted" to an implicit function.

Anyways, Calc 3 gives a sort-of rigorous treatment of implicit functions in general dimensions, vector fields and differentials so to understand this better just research those topics.

Here is my attempt:

Blackholes are it. If you get sucked up, you might seem dead and not dead all at once. Since the laws of physics do not apply in a blackhole, anything can happen.

Pretty half-assed on my end.
You try.

Inside the ordered universe, there are such terrible things that can happen to someone. For example getting tortured by a cartel just for fun, because you are a tourist and they happened to be coked up and horny for pain.
Just imagine floating outside the ordered universe, in the chaos of orderless unreality, witnessing the real inhuman depths of the extreme reaches of experience when reality itself mercilessely melts and bubbles around you.

Hey guys,

I've got a piece of fortran code, that I need to translate to c++ and I'm having hard time understanding or even finding information about the meaning of this pink 2 (see pic, .f file with default notepad++ coloring).

I assume it's not a part of equation itself, but some kind of label. Everything that google throws at me, doesn't really make sense in this situation. Can anyone elaborate, please?

Thanks!
