oops i meant mercury/toothpaste and mercury/deoderant *reactions*

are you ready for this?

they put the guy in charge of Windows Vista in charge of Vaccines

are you studying biology in uni or are you in high school?

either way it depends on which field you specialise into, i think the "hottest" now is bioinformatics/biotech

Concentrate on transferable skills. What's hot today may be old hat in five years time. A lot of gene jockeys got burned way back.

The US BLS has a fairly comprehensive list of all the occupations available. See which jobs you can apply your degree to.

There is still lots of empty space in Canada and Russia if it's too warm for you but most people like it warm.

yeah

but really climate change controversy stems from a dispute regarding human involvement

>>7806358
Yes

global warming isn't real

>-18 c
That isn't even cold. You don't even need mittens at that temperature.

Guys also want to kill their fathers because the dad gets to plow the mom but the son doesn't.

Its the same reason why Dads hate their daughters boyfriend.

>Freudian psychology
Not science

>>7806380
It's kinda science, because it's recording patterns in data. In this case, human behavior. Neuroscience is the only real science, but psychology, even Freudian psychology is helpful in understanding human behavior, even if it's not entirely rigorous.

It's a useful short-cut, like the dumb memetic devices you used to remember shit in school, or 'carrying' numbers in addition. It works, so we use it.

Not Surprised.

Prepare to be assblasted by all of the white inventions on that list if you are a nigger.

Yeah, I don't know man. It takes me like half a day to get through a chapter with a few examples, and by the time the first tests start I'm considerably behind.

Should I take up a job sweeping chimneys instead?

Who knows in this downturn

The same reason hitting a magnet with a hammer demagnetize it.

Taking a guess based on background knowledge: assuming it is something like an iron nail, the material is already prone to "picking up" magnetism. By aligning it with the Earth's field, you are providing a weak magnetic order. By striking the bar, phonons propagate and allow a source for spin-flip interactions that allow the bar to pick up a weak ferromagnetic order, making itself magnetic.

>>7806149
I know they used to make these lock assemblies with magnetic pins, in the 80's so it would stick to any ferric picking tools and complicate any attempt to pick them open or bypass them.

So, we'd just hit the mainbody with a hammer, and via magic physics properties, it'd kill the magnetic field or someshit and I'd just pick that shit open with our regular ass steel tools.

I still don't know why it worked, but it did. It further strengthened my belief that a regular-ass hammer can fix and solve so many problems if it's all you have.

>>7806029
One theory is that there are multiple universes and you are only conscious and aware and 'alive' is because you are in the one universe where it's possible to be alive.

So in most other universes, we all got killed a million times over during the cold war. So reality seems more bizzare as it goes along 'I can't believe we actually survived all that historical shit!' it's because if we had not, you would not be conscious to observe it, so since you can only observe a reality where human life persisted, the world/ timeline/ history gets more and more unbelievable and amazing.

Also, Fermi Paradox. Maybe humans are the only intelligent life weird enough to obsess about conquering the galaxy, other aliens are content living a carbon-neutral, biosphere-friendly life on a sustainable planet, forever and don't even listen to the radio because they love their kids too much to even care?

A year is 12 months. A month is the time it takes the moon to orbit the earth.

they did that because it lined up so the seasons would come at roughly the same time every year

100 years ago there wasn't such a thing as weekends.

What are they wrong about?

not him, but the way they go about classifying chemicals as hazardous is really, really, really bad.

>>7805585
LOL

What's your best guess?

>>7805574

Distances. It's literally non-negative distances.

You might fly from New York to Chicago in a straight line (1500 miles, say), and then back to Chicago from New York (1500 miles), but you wouldn't characterize either trip as "-1500 miles". Not under normal circumstances, anyway.

Any time you have some model, or case x of something (or change x to something) which is manifestly non-negative, it's time to start thinking about abs(x). It might not be necessary in the end, but that's where your head should start going.

There are certain elementary calc identities which entail absolute value, as your picture suggests. But of course this is a bit more abstract when the idea of absolute value itself is as simple as can be. I would hazard to tell you what you're really having a hard time with. It's not the notion of absolute value, but just how this-or-that train of thought in a calculus problem was developed.

>>7805574
Someone please tell me if I'm wrong.

In the last equation, there is an equality and one side is being multiplied by x squared.

x squared will always be positive, and the absolute value of cx will also always be positive. If one side is always positive, then the other will also be always positive. So you can just remove the absolute value because it changes nothing.

Is my reasoning correct? I have not yet seen these kind of problems on my own. Just a freshman baby.
