Have to choose my degree, I have 2 options

>Bachelor of Engineering, Biomedical. 4 years long. A Masters then requires a further 2 years of study

>Bachelor of Engineering, Mechanical. 4 years long but has an integrated Masters programme which only takes 1 year extra.

Which should I go with. I have heard that Mechanical Engineering is a much more versatile degree and will allow me to work in a variety of positions, whereas a degree with Biomedical Engineering has much more limited career opportunities

Some...

BEng in ME with bio classes for your electives, then Master's in BE

>>7754352
Why?
>>
>>7754349
You don't need a masters unless you plan on attending some shit-tier European university or something.

Also BiomedE is a meme.

>Some people have even told me that whereas a Mechanical Engineer can do the work of a Biomed Engineer, a Biomed cannot work in the post of a Mechanical engineer. Is this true?
Yes. Why else do you think it's a meme degree?

I wonder if it's possible to have a really high iq and be poor at learning physics
>>
>>7754312
no sorry you're just retarded

>>7754312
Yes, I have a genius IQ and I'm poor at learning physics. I always try to study QCD but then I get distracted by more interesting and more intellectually challenging things due to my high IQ.
>>
>>7754391
>>7754391
I have the same problem, although I specifically get distracted by things that are more interesting and intellectually challenging than the ones you get distracted by, due to my high IQ, which is higher than your high IQ.

72 KB,
Is there a scientific reason why we can easily maintain focus 24 hours straight playing a video game or binge watch TV series with no sleep, but spend just 5 mins studying physics/chemistry and we get bored already?

Why do our brains not show as much enthusiasm in studying than when playing games?

Why did the smart kids in high school not play video games?

>>7754271
Dopamine receptors are overexcited by all that stimulation. Cutting back on playing video games and watching tv that much might be able to lower that very high threshold you currently have. Meditation might also aid you in the process.

Which path should I choose Algrebra, Analysis or Geometry?
I'm an undergraduate pure math student

Whichever one you like most

And then you'll realize all math is one and making a choice is silly

Algebra and geometry are the same thing.

Analysis is if you don't like rigid mathematics

I got 40% in grade 10 geometry. If im not good at geo, you arent, so do algebra, because solving for x is fun

If so many scientists are such raging liberals, why don't they boycott/ take a stand against the racket run by journal publishers?

Tenure committees and granting agencies still see a publication in Science or Nature as recognition.

To a pretenured professor, recognition = grant dollars = continued job. The publication costs are often included in the grant budget.

Scientists dare not complain, since it's so easy to be blacklisted from funding agencies. Trust me.

File: expand arc length.png (769 KB, 1125x800) Image search: [iqdb] [SauceNao] [Google]
769 KB,
I'm having trouble deriving arc length of functions. I'm using a vector-oriented approach, if that's alright. I'm doing this because I don't understand the $1+(f')^2$ part of the standard formula, and I don't like using formulae I don't understand.

So far I have this:
Let $d(\vec{u},\vec{v})$ be the Euclidean distance function between two vectors $\vec{u}$ and $\vec{v}$, defined by [eqn]d(\vec{u},\vec{v})=\left \| \vec{v}-\vec{u} \right \|[/eqn]. Let $f(x)$ be any "reasonable"...

Why don't the eqn tags work?

>he proof works as long as it's continuous, actually. I could be wrong.
f needs to be of bounded variation

>I'm not sure how to get rid of that h and replace it with a derivative
Pull h out of the square root. Also you start with a sum, not with an integral. So you obtain the integral in the limit.

12 KB,
How do we know if Euclid's theorem is the same for every instance? (euclid's theorem is a proof that there are infinite prime numbers by contradiction, stating that for every finite series of prime numbers there can always be a new prime number generated from that list) but how do we know that this applies every time?
>>
because euclid proved it
>>
>>7753981

If you are asking this, you don't understand the proof.
>>
>>7753981
>how do we know that this applies every time

Because it doesn't matter how long your list of primes is, by constructing a new number in the way he specified you show that the list is incomplete.

If you are this thickheaded then I recommend making a finite list of primes, using his instructions to construct the new number and then try to factorize that new number with only the primes in your list.

Why do I have to spend a third of my life asleep?

It just seems so ridiculous to me that I need to throw away a third of my life in order to function like a normal human being. How could humans have evolved to do this?

Is there any way around it?

probably because we can't see shit in the night so we're better off conserving energy and secreting growth hormones instead.

I went for about ten years sleeping two hours or less per night.

I really liked having all the extra time, but it had its downside. I tend to have quite enjoyable dreams but during that ten years I would only dream three or four times a year.

When I went to sleep I never went to sleep so deep that I couldn't become fully alert instantly.

I heard they are already working on neural prosthetics. That they are taking injured Iraq war veterans with brain damage and trying to restore cognitive ability with computer chips.

They're are only a couple things you should really focus on:
Arithmetic on fractions
Working with nested fractions
polynomial arithmetic
Factoring and solving polynomials
Polynomial long division
Everything else is formulas or covered later (in precalc or LA or calculus)

A challenge for you nerds:

Make a meal plan for a day or a week with a $15/day budget that meets every nutritional need. No vitamin pills, as you can never be sure what's in them, and even if you could be sure, it's been shown that (at least some) vitamins in pills do not have the same effects as vitamins in real foods. No stupid shit like 'eat 500g seaweed' or 'buy a whole cow and freeze it and slowly consume it over several months' or 'eat goat testicles' I bet you can't do it 79 replies and 5 images submitted.

you could do that on 5 a day easily

Are chemists good at math?
>>
>>7753664
Depends on the type of chemist, and the type of math.
>>
>>7753664
physical chemists are probably pretty decent at math/were interested in math as undergrads. Good deal of group theory, PDEs, etc. from what little I've seen in more 'applied' QM texts like Slater's atomic/molecular theory books.

>>7753672
What about organic chemists, chemical biologists, biochemists
