/sci/ - Science & Math

People don't like realising they're ignorant.

That makes them feel inferior so they try to devalue your apparent greater knowledge.

'Haha Anon you're such a nerd for knowing about science and stuff!'

It's just people trying to maintain a sense of ego. I feel sorry for them

I trip fag so I can be identified when I want to keep a dialogue going.

Also I like the attention.

Met my girlfriend of three years when she was the sound tech in a panto in which I was the lead boy.

We chatted every night on msn for a year, we became best friends. I asked her out at the casting for next years panto, she was assistant director at this point.

We've now been living together for two years.

Sorry if I forgot about the fridge coolants and some freaky cubane structures. I was to busy thinking about the other 99% of organic chemistry.

Christ chill the fuck out.

If you want to make money and not be a lab rat, get a PHD. Worth the fucking three years, you will almost invariably get more connections just from doing it.

Night falls so does the temp, surface frost forms on the stone, stone moves in fuck strong wind about a millimetre.

Next night same thing. Nothing to disturb the tracks they hang around for a while.

Complex carbon systems are energetically favourable.

Carbon is the element with the second most possible compounds, second only to hydrogen because hydrogen is in all the carbon molecules.

Carbon has a greater affinity for complexity, caternation.

Silicon can't do it and nothing else supports enough complexity so efficiently.

I can definitely talk about chemistry better when drunk.

It is very difficult to say, local weather is difficult to predict, we will experience more extremes as higher moisture content makes it easier for temperatures to shift dramatically.

This weather would be exceptional, as in, worthy of putting down to a miracle, in the past. Now it is common and events like this with weather disparate to season will become more and more common.

The best way to see this is to study seasonal organisms, they are getting fucked over by the constant weather fuckery.

Christ the list goes on and these are the ones that come off the top of my head.

And to the Americans out there, imagine watchign TV without ad-breaks.

a visual demonstration of sea ice extent in the arctic since 1979. From the NSIDC.

I smell bullshit..... doesn't look like any I've seen on NSICD before.

Reverse image search shows no hits on NSIDC.

Learn to check the facts. I hate to generalise but the hoaxers don't check their own facts.

actual website, scroll down two articles.

Are the thermal properties of methane understood?

Yes, yet again see IR spectra. Methane is actually a much more effective GHG as it has an effective duration in the atmosphere of 15 years.

Has the concentration of Methane in the atmosphere increased and what has changed to cause this?

Yes, an increasing concentration of methane producing livestock, gas pocket release and the defrosting of trapped methane.

Surely the planet has mechanisms for dealing with raised CO2, temperature and methane levels?

Yes, the ocean acts as the buffer solution of the planet absorbing CO2 and expanding in increased temperatures. The ecosystem enhances this affect via photosynthesis, organisms in the ocean dying and then being stored in the crust.

So there's no problem right?

Wrong, we dug that stored carbon up and pumped it into the atmosphere, the ocean has expanded massively already and become acidic, killing off micro organisms responsible for trapping carbon. We forced an equilibrium, it balanced out as long as it could and now it has gone past critical point. The system is now feeding back on itself, any small increase in forcing is now pushing harder and faster.

Are you saying we can't do anything?

We can stop making it worse.

So are you saying that people that don't 'believe' in anthropogenic climate change as bad as people that don't 'believe' in evolution?

Pretty much, and like evolution it happens whether you believe it or not. There are books for people like you, here's the link.

Time to drop my basics of climate change pasta...

Science up in this bitch.

Have the thermal properties of carbon dioxide been known about since the turn of the century?

Yes

Have they been refined and improved on by the Air Force within the last decade?

Yes, they like their heat seeking missiles to behave.

What are those properties?

Well the C=O double bond absorbs infrared light as most bonds do, the C=O double bond is a really nice intense peak in IR spectra, I use it to identify Ketones and Aldehydes.

Does carbon have a handy built in way of aging it?

Yes carbon dating.

What would happen if you burnt an old source of carbon such as a fossil fuel?

You would release decayed CO2.

Can we measure an increase in the ratio of decayed CO2 to nondecayed CO2?

Yes we can, to such an extent that carbon dating is now unusable for future generations as there is now a spike starting around 1890 and still climbing.

Is this just happening because the undecayed CO2 is magically dissapearing?

No, total CO2 concentration has and is going up.

What would the expected effects of an increase in CO2 concentration be?

A warming troposphere and a cooling stratosphere as the the heat is prevented from reaching higher atmosphere due to the CO2.

Is this seen?

Yes.

What would the affects of a rising temperature in the troposphere be?

An increase in moisture content of the air. A depletion of heat sinks such as ocean expansion and phase system changes (e.g. Ice caps)

Are the thermal properties of water well known?

Yes, again see IR spectra.

What would increase moisture in the air do?

Trap more heat in the troposphere causing a feedback loop.

What does a feedback loop do?

Cause more heating, which causes more feedback such as freeze trapped methane in the northern hemisphere.

If you are weighing something precisely you isolate it from atmospheric fluctuation, and then zero the instrument. You take the pressure of the atmosphere into account with your measurements.

See it in book for first time, can deduce what it's structure is.

Theobromine? Fuck that.

Just AH the rage. The rage in my heart right now.

oh god fucking damn it!

The whole case is based on the fact that the scientists made a statement that citizens shouldn't worry. This is why you don't make a prediction if you can't make a prediction. People assume we know what we're talking about.

Bitch please.
I had the horrid sciences and the horrid Geographies. Wierdly not as good as the HHs though.

These books are brilliant for getting you into a subject.

For most who are going to do nothing but sit in a cubicle for the rest of their lives they don't NEED any education beyond the age of 11.

However, I didn't know I was smart till I was 10, I thought I was pretty average and nice, it wasn't till they started testing me that I started showing I was 'smart'.

10 GCSEs 1 A* 7A 2B

I did no work for GCSE, AT ALL.

A Level

B in Drama, D in physics, D in chemistry

I worked my self to death and a D was all I got.

I am now studying Chemistry on route for a 2:1 maybe a first if I really pull my finger out.

Formal education isn't even good for those that need it in their subject. For example me with chemistry. University is essentially vocational it just happens that instead of teaching me to use a trowl to lay bricks they teach me to use my mind to do chemistry.

Panspermia? Sure, abiogenisis happened somewhere. We have the perfect serpentising crust for life to form on so why not here.

Aliens purposefully placed the first organisms on this planet? Sure but see above.

Anything else? Nah you're a retard.
