I'm not even denying manmade climate change, but you're arguing against a strawman.
Global warming is something that can be observed. Human involvement in it is the thing that people are sceptic of.

You are changing the subject. There have clearly been claims that global warming itself is not happening, and that this is just the natural wavering of temperature over centuries.

I love how the most vocal fuckers are constantly conflating different subjects. It's just like anti-evolution switching subject to abiogenesis. I don't care what you believe and am open to discussion, but please keep your topics straight.

No we deny temperature rising too, tons of corruption and modified data has been proved, while the only "real" data we have, satellite data show no rise in temperature in the last 18 years.

The process of mitosis. The fundamental process of asexual reproduction. The scope of mitosis is to segregate the genomic information in two cells. Here we see the chromosomes in red and the microtubules in green. After the chromosome condensation the microtubules organize in a spider like structure. They are ready to pull the DNA at the opposite poles of the cell. Once the chromosomes are separated the cell goes into anaphase then telophase and divides.

"Spooky action at a distance".

2 particles are involved in quantum entanglement and when one is measured the state of the other particle is instantly known, sure. But I really don't understand why this is considered spooky or strange. Why can't these particles ALWAYS be opposites, regardless of anything? Is it so weird to be able to see what side of the coin is facing the floor when you toss it?
>>
For starters, action at a distance was resolved a long time ago, with the introduction of the force field to physics.

Entanglement is peculiar because the moment the state of one particle is determined, the probabilistic nature of the other is "collapsed" and it's state is known as well. The surprising part is that if the particles are physically separated, it doesn't seem as if there is any time delay between the two measurements. In other words, they happen instantaneously. That really just means that no signal or wave or whatever is being sent from...

I'm self-studying and completing the exercises. This text doesn't have any solutions to the proofs and even though I'm confident I'm doing some of these problems correctly I have no way of knowing 100% if I made a mistake somewhere.

This can give the reader a false sense of security they are doing the exercises correctly without validating their work.

Why are math textbooks like this?

Correction: observable matter only holds 5% of the total energy content of the Universe. The rest is divided into matter which we cannot see, and an energy density of free space which drives the accelerated expansion of spacetime.

>>
>>8109193
Well, by that logic, physics, chemistry and biology aren't sciences either since they are physical sciences and life science accordingly. How about you read up on what neuroscience is and decide for yourself? Also, I've heard so many people tell me they are interested in neuroscience it's not even funny. Neuroscience is a subfield of biology. Are you interested in biology? Do you know anything about it?

If you trust your friend's dumb definition, you probably won't succeed in science...

I want to know right now, WHY DON'T THESE GUYS GET PAYED A SHIT TON MORE MONEY?!??!

How little they are paid should make it clear that they are really not that important at all.

This is exactly the issue, most postdocs are working on some weird extremely specific research project that has a few applications in its field and will have no meaningful impact on anyone's lives outside of academia. The vast majority of academic research is like this, and most of the research with actual real-world applications involves some level of equipment and is done by experienced professors or researchers...
