/sci/ - Science & Math

The real question should be.
Is pure chemistry actually useful?

My psychologist girlfriend read it and read many a passage to me, enough that I bought it for my no-science father for his bday.

Chemistry is full of a lot of girls that weren't that popular in school but are all that awesome thing of a hot nerd girl. They are almost entirely cock mad and with a lack of good looking guys on their course the few of us that are passably attractive have had a great time.

you clearly don't understand fire properly.

Career wise:
So much more stuff to do at every tier. Potentially making very good money.

Studying wise:
Cohort is much more personable, we're all slightly crazy and damn good fun.

Ability to make a difference:
As a chemist you can make a much larger impact than in physics, you can get your name all over sythesis paths and crap like that.

Chemistry is just damn good fun for damn good pay.

I say yes purely because I can actually do things and see things working. Doing something useful is always more fun than making up random crap.

You throw stuff together and favourable reactions go forward, it is all working with percentages, you turn your toluene into a solution of toluene plus something where you want it and toluene with stuff everywhere else, then you seperate the stuff you want out.

That is how synthesis works in the end.

The issue is slippery slope.

Is being born blind a disability to be changed?
yes
Is being born short sighted a disability to be changed?
maybe.......
Is being born ginger?
Is being born black?

This is the issue, when do we stop?

I'd love us to add inherent immunity to all diseases to the human race, but what else do we change?

Me and a group of friends play a CSI drinking game, any time they say anything that makes no sense take a shot.

Putting solid samples through GCMS.

Getting no 'peaks' (no one in the industry calls them that) from samples they put through GC:MS.

All their wierd data displays.

The whole thing is agony for an Analytical Chemist.

My third year chemistry project is constructing a cheap readily reproducable water filter.

It's based on that wonderful wonder material graphene. When layers of it are formed in parrallel they exhibit a unique property, the graphene lets only water pass through.

The filter could essentially filter raw sewage and give drinkable water.

Catalytic converters turn CO to CO2, going to mono-atomic O is damn tricky.

We cannot detect and discern a vast majority of the energy flying around us.

But just think how wasteful it is, all this reflected energy, at least we SEE the visible spectrum every other spectrum is serving no purpose but warming the earth.

Mailing it to a proffessional.

This board is not for the sensible discussion of scientific theories. It is for us to chat bollocks about science and feel big about ourselves, and I like feeling big by answering GCSE level Chemistry Questions.

Fuck it go for space opera science.
Quarks are paired you cannot seperate this pairing, the strength of the bond goes up exponentially with distance.

Seperate them with space awesome power stuff.

Say that the space between gains wierd properties, call it a quark pair splitting field. Feed stuff in it is 100% converted to energy along the E=MC^2 line.

Have fun with your space opera techno babble!

Captain the QPSF is collapsing!
Reverse the polarity!
genius captain!

Well depends what you liquid you give me, as an analytical chemist if you ask me to tell you what is in a random fluid I will first ask you questions.

But imagining I can't ask you questions for whatever reason.

LCMS to give me a rough idea of whats in it.
GCMS to quantify more precisely.
IRspec to determine bonds and from that structure.
NMR for further structure if it proves organic.
And go from there.

Well I am on the south coast of england I have no predators save wolves, assuming the fish populations are at their acient levels I can just fish pot the coast and have that as my agriculture.

Clay is rich here so pots can be made.

Can dry catch salt from the non-polluted sea, so can preserve my fish in my pots. Hell just put them in brine.

Lacking citrus fruit I can't make effective batteries easily.

I can get tin from the local surface deposits so theres rudimentery tools and battery components.

Fermenting long-grain grass for ethanol and such.

Get a saltpeter piss processor going, hygeine and materials in one.

Charcoal burning of the trees allows me to get materials and ores more effectively.

That's the first year.

Book wise. Probably something on the engineering front.

My tool? Portable command computer, the shit the army uses that has solar power and turbine power. Inbuilt RF broadcaster and remote control capabilities and everything else I could need for my unmanned aeronautics. Also a base for all my tech.

Chemistry cubed or Chemistry3 as it's known to amazon.

Really good intro to chemistry.

Every single molecule is constantly shifting around, its electrons moving through every orbital it can and moving through quantum states. Bond are breaking and being remade. Due to the sheer number of molecules in solution the probabilities give you a single structure. Hybrid structures provide two structures that can be formed that can be counted as one, which of course raises the probability.

It is difficult to communicate two years of A-level and Two years of a degree in a single post.

It is a combination of reasons.

Orbital shape creates a stearic affect, it is less favourable to hybridise comparative to the pi orbital bond.

The pi bond breaks first as it is less stable than the sigma bond.

I am using the world 'viable' to encompass what is within the range of possible in a universe where there is a company dedicated to terroforming planets.

Getting to 0.5c is doable, they could have been using fusion engines or anything else that they want to pull out their ass.

The Nostromo was 20 years into a 200 year mission when they got waylaid by the beacon.

.......
The alien universe doesn't have FTL in 2480, it most definitely doesn't have it in 2080.

Suspension of disbelief is them coming out of orbit and stumbling on the structure straight away.

Them being inconsistent about tech is just them being inconsistent with their shitty Lost script.

Them being in cryo sleep for a few hundreds years wouldn't matter cos the film isn't exactly in real time, we didn't watch the two year journey so why not skip forward a few hundred? It has happened SEVERAL times in the franchise before.

They didn't. They went to 10*10^14km from earth, traveling at 0.5c for two years, this is viable, the problem is that that's in the oort cloud.
