You know that there is actually more than 1 type of fish, right?

Some of them - get this - aren't even contaminated with mercury.

There are some parts of the ocean that actually don't have any mercury at all.

I thought we just shitpost about how whitey is smarter than niggers.

Did we switch?

That's what our little /pol/tard shitposter does. He just posts an IQ thread. If he's asked to support his views, or he doesn't get the attention he wants, he'll crawl back in his hole for a day, and post the same shit again tomorrow.

Read Stephan Covey and Maxwell's writing. Each day matters. Plan 10 things to do tomorrow. Make it a goal to not stop until those 10 things are done. List them in order of importance, with the most important thing first. Do not beat yourself up if you do not accomplish all 10 things. Even if you only accomplish 2 things, those are the most important.

If you do them all, tomorrow list 11 things. Same thing.

If you make it a habit to follow lists, you will eventually succeed or die trying.

Interesting how men named James Mullen are all so powerful: CEO at Patheon, Director of Security at Walt Disney, CFO Dyson, TRP Associates cofounder.

Wrong Jane you ignorant slut.
Causality does NOT imply exclusive causality.
The temperature could have been too cold.

False, in that the statement does not hold true from the premises given.

I assembled some equipment for a homelab and I have a few questions on gas collection.
I can't find any of the equipment I ever used for gas collection, as they are all much more expensive than I can afford so I'm looking for help here.
What should I use to combust sulfur to sulfur dioxide and collect it?

Homelab experiments
I'm planning in synthesizing Sulphuric Acid and Hydrochloric Acid in my home lab.
I have 5 lbs of Sulfur
My plan was the combustion reaction S+O2→SO2
then 2SO2+O2→2SO3 (using V2O5 as a catalyst)
Then SO3+H2O→H2SO4
The problems are that I don't know where to get V2O5 and that the final reaction is highly exothermic.
Any help or advice?

What can you do with a BA in economics? Thinking about picking it up as a second major. Was originally thinking a math major, but I don't really like it that much any more. Currently a CS major.

If you are so certain about what's going on with the climate, why not focus on that instead of unsupported accusations?

And then:
>The probability of humans producing global warming , anywhere in the universe from supposed polluting processes, with even hundreds of years to do it, is as reasonable as getting a fully operational Boeing 747 jumbo jet from a tornado going through a junkyard.

Could we see the calculation behind this?

A lot of people seem to misunderstand what happens in an atom.

Electrons, despite what you are probably told in science class, don't actually 'orbit' the nucleus.

Instead, there exists around the nucleus a kind of cloud, made of what is known as a probability density. It's not a physical cloud, in that it is not made of any physical substance. The idea is that the probability density is greatest at the point you are most likely to find the electron. In a Hydrogen atom for example, you can show that the probability density function is maximum at 1.5 times the bohr radius.

Before you make a measurement of the electron, you don't know where it is. It could be somewhere in the cloud. The really dense parts of the cloud are the most likely places to find it, but it could also be found in the less dense parts.

The REALLY bizarre thing that most people can't seem to grasp, is that before you measure where the electron is, it isn't really anywhere. That is, it is not moving around the nucleus. It's wavefunction (which is intimately related to the probability density 'cloud') represents the electron, and when you measure where the electron is (at, say, 1.3 times the bohr radius) then you have collapsed the wavefunction so that instead of a cloud, you now have a well defined position. The cloud becomes a really small, really dense point.

TL;DR - electrons don't orbit the nucleus like planets orbit the sun. That works for classical mechanics, but Quantum Mechanics is different.
