/sci/ - Science & Math

Did an event which has no witnesses and leaves no trace really happen or not? I am genuinely interested in your opinions.

What the fuck is isospin? I don't get it. Why should everything remain invariant when you arbitrarily replace protons and neutrons? It's not the same. They're different particles ffs.

>Chemical Engineering: 5,900 undergrads

Huh. Never would have thought. Is it really that hard?

>Computer Science: 38,500

Thought it'd be lower. Everyone pushed CS so fuckin' much, I'm fairly certain that'll decline in the next ten years.

>Business & Management: 253,736

What the fuck? Why are so many people going into business? Why isn't business a meme degree? The data doesn't lie

>Forensics: 811
> Astronomy: 335
>Atmospheric Sciences: 721

Holy shit. Why so low? 300k starting when?

Quick /sci/, how do we stop climate change?

Is there any value in understanding scientific concepts if you are incapable of understanding the math which supports them?

I'm kind of at a cross-roads, and really admire various sciences, but i currently feel unable to commit the time and energy into going into a lot of it with any degree of depth, and am unable to afford schooling for the sake of pure interest...

Oh god the stupidity.

Didn't know where I should start this,

JAVA HELP NEEDED

how the fuck should I program this table?

0 5 5 5 5
4 0 4 4 4
3 3 0 3 3
2 2 2 0 2
1 1 1 1 0

Any help? I can use only tables and loops

These posts confirm my suspicions that everyone on /sci/ is in high school.

Being able to execute a reaction. Being able to mechanically figure out how to turn reagents into a final product is useless if you don't know how to do it in the real world.

They're thinking of renaming it to the Barnett-Nobel prize.

And try guessing who the next element is going to be named after.

IQ scores are adjusted so the average is 100

I can't find out the answer to:

"100 grams of C2H2 reacts in one step with HCL and creates 120 grams of a product".

The theoretical dividend of this reaction is

A) 20 %
B) 50 %
C) 100%
D) 120%

How do I solve this piece of shit?

First I find nC2H2 by doing :
100g / 26mM = 3,84 moles

But it pretty much stops here.

I'm doing fairly well in chemistry, but there is one subject that I can never wrap my head around and fully understand.

It's under Electrochemistry and the subject of electrochemical series.

The standard " Will this reaction happen"

Example: Explain why we get a reaction when we put a Fe2+-nail in a solution of Cu(NO3), but we don't get a reaction if we put a copper-nail in a solution of FeSO4.

The book always talks about one being in reduced form and the other in a oxidized form, but shit doesn't make sense.

A drawing explaining this would be of tremendous help.

(02:13:36 PM) Jerko: but we are traveling about the universe
(02:13:42 PM) Jerko: is the point of that entire article

(02:14:42 PM) Jerko: so everything in the universe just flings about all willy nilly then

(02:15:25 PM) Jerko: the universe is calming down galaxys are forming into different shapes
(02:15:44 PM) Jerko: there are 3 large galaxys and 33 little galaxies in our cluster
(02:16:05 PM) Jerko: do you read astralphysics and articles?
(02:16:20 PM) Jerko: solar systems form galaxies galaxies form clusters and clusters form something i forget what they are called
(02:16:28 PM) Jerko: and the entire universe is branches

Protip: you can't (yet) write down the "laws of the universe", just convenient models with varying degrees of verisimilitude.

For some reason, I cannot understand this problem:

An 18 karat gold necklace is 75% gold by mass, 16% silver, and 9.0% copper.

A. What is the mass, in grams of the necklace if it contains 0.24 oz of silver.

The correct answer is:

43g of 18-karat gold.

But I cannot wrap my head around how this was answered, please walk be through the steps.

Thanks for your help

>physicists get more pussy than chemists

I suppose it is time to become better acquainted with my virginity. Its going to be a long partnership...

So, on a scale of 1-10, how useless is my degree in biology/animal behaviour? Am I going to be a research whore for the rest of my life, or just going to end up in a mediocre office job?
