why do climate change alarmists not just kill themselves? I mean, do they not realize how big of a carbon footprint the average human leaves on the planet?

>>9058089
The fact that it can't get anything right for a start. Also how we're told that economics are the laws of nature, akin to physics, even though economic models keep fucking up over and over again.

>>9058089
Virtually no predictive capacity.

Everyone should know basic economics and finance well enough to understand the politics around them, but beyond that just not that insightful of a topic. Even most successful investors don't trust mainstream economics.

Can somebody answer pls ;_;

It's almost entirely by chance by mutations.
There's nothing saying that we "should have" or that we were "supposed to" develop the sensory organs or physiology we have today.
The idea is that we just happened to mutate the beginnings of eyeballs, or light receptors, and those individuals bred more because of an advantageous mutation. Thus, the likelihood of further mutations was increased as more and more generations with the genetic structure bread.
It isn't a spontaneous process. It occurs over billions of years with just as many if not more generations slowly developing into what we see today.

I'm a Christian and I believe evolution is just another process by which god created the world. Fuck off.

OP. Think of this: Take any "feature" of an organism. Consider it as having it's own code for activating. Now for that individuals ancestors it took many generations of exposure to certain conditions for the code to react to the same condition. Each generation having it's code effected by it.. such as radiation in the form of uv. Over time there is a new feature muddled together by using other features' code or snippets of "damaged" code in a new individual. That is a case of how traits can form. Likewise, redundant features may be retained in the library of the organisms code that can be used later for responding to new conditions that generate new features.

They actually don't give you a full sequence, only selected SNPs. But yes it is pretty useful and you can throw it into various software packages or websites to get detailed information.

Parasites are by definition harmful to the organism.

>>9057842
No.
>>9057834
No.

>>9057842

Pfff. No.

Parasites want their hosts to be well. There is evolutionary pressure for them to help their host. There are other forces at work, so its a trade off, but ceteris paribus parasites are on your team biologically speaking.

We already know the human body is in symbiosis with many bacteria. Gut bacteria for example, are necessary for your digestion. There are probably many parasites that are a part of human biology that play crucial biological roles that we just havent discovered.

Enjoy spending another 8 years in school learning why 1+1=2. While Chad is a project manager and going to hire your sorry ass to be a human calculator.

That's no way to start a thread.

Try posting some content, like this:


theory tl;dr:
> spin a high-momentum superconducting "donut" at high speed (to generate a gravitoelectromagnetic field)
> submerge the "donut" in liquid helium (which flows with near-zero resistance and with angular momentum dependent on temperature)
> the liquid helium has ferritic nanoparticles in it (so the fluid and the donut spin at the same speed)
> use a silver wire coil in the liquid helium to ??? change the temperature of the liquid helium changing its angular momentum
> ???? this strongly intensifies the gravitoelectromagnetic field
> ??????? this creates an area of gravitational repulsion inside the "bell" proelling the UFO upward

"This experiment is the gravitational analogue of Faraday's electromagnetic induction experiment in 1831. It demonstrates that a superconductive gyroscope is capable of generating a powerful gravitomagnetic field, and is therefore the gravitational counterpart of the magnetic coil. Depending on further confirmation, this effect could form the basis for a new technological domain, which would have numerous applications in space and other high-tech sectors" says de Matos. "We ran more than 250 experiments, improved the facility over 3 years and discussed the validity of the results for 8 months before making this announcement. Now we are confident about the measurement," says Tajmar, who performed the experiments.

> In 2004 Penn State's Chan and Eun-Seong Kim rotated a ring full of solid helium at 26 atmospheres of pressure and found that as they cooled the helium below the critical temperature, the rotational frequency increased, just as it does with liquid helium. Half a dozen laboratories, including Beamish's, are studying the "supersolid" effect, but researchers still aren't sure which elements of the solid would condense into a single Bose–Einstein state.

And from the other thread:

https://en.wikipedia.org/wiki/German_submarine_U-864
U864 was transporting mercury, allegedly to japan. interesting about it is that mercury is mentioned in some ancient script as some kind of fuel for ancient machines. (would have to look into that to be honest, but heard about this a few times now)
however another thing about mercury is that its mentioned in pic related which allegedly describes the workings of the glocke. an anon mentioned it could be a scalar device that draws out energy from the ether. cant tell obviously, but maybe one of you can.

They always swim against the flow. There's an artificial current in the tank created by the pump.

>>9056952
Ok. Didnt know that. But theoretically. If there were no artifical stream, and they were floating on their own, which direction would water spin?

>>9056954
Clockwise.

On one hand, this was the book which personally got me to see the beauty in math. On the other hand, with a few years of hindsight, there are some serious problems. It's really for a student which has never seen proofs before, but it's not a terribly introduction to proofs. It avoids the language of sets and topological notions, only really pushing epsilons and deltas. Even from this perspective, lots of the proofs are really bad, especially considering the intended audience. It'd be very difficult to learn how to do epsilon-delta manipulations from reading this book alone.
The book is still very enjoyable to read, and the exercises are fairly excellent. I think this book can work well in an actual class, with the instructor supplementing many points where the book is weak, but I can't recommend it for self study purposes. Analysis I by Tao is a much better alternative for the same level of background, and ultimately covers more extremely relevant material.

If you're white or Asian, probably not.

I'm just telling the truth.

the only way to get a guaranteed successful tenure track is if you're a woman or black. both for ivy league. you can still do it, but you'd have to be more gifted.

Explain further on math degree.

You need at least a minimum of a MS, but a PhD will most likely guarantee you the tenured position.
>>9056467
You're telling the truth, because whites and EAST asians get into the actual unis.
Not insulting CC, but OP's being lazy maybe so that's why he's saying CCs
