Should I double major?

I am currently studying Computer Engineering Technology and I'm thinking about adding Physics.
Will it help anons? Anyone here with a Physics major and ended up loving it?
Also I'm a girl and a Sophomore :3

Alright, /sci/

I'm working through some basic triple integrals - stuff like volumes between cones and hemispheres. Setting up these integrals usually isn't too bad, but almost always ends up placing at least one or two square root functions in the integrand.

Now, I know that we have some techniques to deal with this. Trig subs come to mind, but usually end up messy if they're in the middle integral.

I'm also aware that converting them to cylindrical or spherical coordinates can clean things up, but the section I'm working from now only deals with cartesian coordinates. And yet, they are able to pull exact answers out of these things.

Is there something major I'm missing here that simplifies these kinds of integrals?

It's called an anaerobic digestion (AD) plant you plebs and it's used extensively. When did /sci/ become this stupid, oh yeah it always has been
> cant even basic technology

Shove in trash,it's processed, bacteria feed of it producing concentrated methane "biogas", solid waste produced by bacteria is spread over local farmland as a rich fertilizer. Normally found near landfills.

im looking for a rather obscure book for free called HDEV by rathus. tried all the search sites on scis guide and nothing showed up. help. pic unrelated.

How does one get into an Ivy league university?
thinking about CC beforehand, will work ass off.

Poorfag here.

Hello /sci/
How does one find their passion / Desires in life?

Ive narrowed it down that anything besides a slavic retail job (Including LOL College) requires at-least a bit love of what one is doing..
I'm interested in starting my own business but 500$ wont get rather far..

Would like to travel ,
Minimalist.
Good at visual thinking, creative that way.
Good at math.
Won't do anything devilry in nature.

Would love to work in neurology, or somehow advancing this world, do you know how to do this?

Sup /sci/,

When calculating a volume of a gas using a varying pressure and temperature, does the temperature unit have to be degrees Celsius when the we're using pascals for pressure?

So, I was wondering..
With my limited amount of knowledge of cosmology..

Expansion of universe..
We can compare this to a very concentrated substance, being released into a space where this substance is not present (a vacuum if you will)
The substance will keep expanding up untill the point where the concentration of the substance will be the same everywhere. (This does not mean the substance is static in this space, but that doesn't matter at the moment..)
Okay, so basically matter is energy in some way or form and it is converted into space. If not, space is still expanding and the energy it contains is being spread thinner and thinner.
Now my question..
What happens when the universe has become so big and so old that all the energy has been spread out completely, making it a perfectly homogenic volume. It still contains all the eregy is once had, but so strung out, we can call it infinitesimal.
We could compare it to a perfect crystal where all the energy is evenly spread out in space..
What happens then??

cos (x) + cos (3x) = 1/2
Trying to find solutions for x over 0 < x < pi but I'm fucking clueless
Any help/clues/hints/anything?

So, Doppler effect, explaining how wavelengths are becoming shorter when speed of observer is faster than speed of source and wavelengths become longer when speed of observer is slower than speed of source.
(Example, Red shift in universe)

To explain why the speed of light isn't constant from every point of reference:
I think that the lesser amount of wavelengts per second, reaching your eye, is an indication of increased speed from the source, as the star is moving faster away from us, the amount of wavelengths reaching us observing will become less aswell.
The light itself doesn't change in speed, it still has the same properties because it's constantly emitted from the same source.
We are just moving slower than the source, allowing a decreased amount of wavelengths reaching us on a high enough level that we can see a frequency change.
The light is still traveling at light speed, only not for us. For us it is traveling at a lower speed. (Not much, but significantly to see the change)
I mean, let's face it, it's not like the properties of the emitted wave coming from the source are going to change just because we want it (change in wavelength), it's the change in speed that accounts for all of this.

Are all linuxfags leetist?

then start a thread about an interesting topic. /sci only devolves into those threads when there's nothing else to talk about.

Q5 part c, should it not be 1.1 instead of 0.9? studying for this exam and a quick yay/nay would be nice

http://www.msnbc.msn.com/id/19374216/ns/health-sexual_health

why is it that men on average have more sexual partners than women? i can understand a difference on the MEAN, but not on the average, are people just such fucking liars? even when being anonymous? or maybe both men and women use different criteria to determine what constitutes sexual partners (e.g. men consider someone who gave them a handjob a sexual partner while women only consider men who penetrated them a sexual partner).

For men to have had that amount of partners it is necessary that women had the same amount of partners (unless, of course, that homosexual men are having so much sex that they're skewing the statistic, but i doubt that)

Hey /sci/ducks,

After raging at the Hawking comments on Yahoo, I thought we should emerse ourselves in some science-related music. Really scientific titles: no shit like "Here Comes the Sun."

For you metalheads: Type O Negative - Gravitational Constant - G = 6.67 x 10^-8 cm-3 gm-1 sec^-2

if someone were to travel at 99% the speed of light, even though people on earth would observe that person to age slower, the person traveling that fast would observe him/herself to age at the same rate should he/she live on earth (assuming diseases and etc. didn't affect the aging)

is this true?

Hi guys... I just took a Business Calc test today on logarithmic functions and such... I'll just be on my way then....
