This giant of biology has recently passed at the age of 97. What's the verdict? Gifted pioneer of scientific inquiry or scheming, bigoted plagiarist? There is no middle ground.

So why can’t we transplant heads?

The Concept is interesting, magnetic poles fluctuating so hard it completely flips the map, Magnetosphere fucked up, apocalyptic storms, etc. etc., but I don't really know anything serious about it. All the mainstream sources just calls anything like this a "hoax" or a "theory", and this sort of thing is too esoteric to be discussed with /pol/fags and /v/tards, so tell me /sci/, What is the Polar shift? give me some serious info on this.

Polar flips do occur. We can be confident of this based on varying spin alignments in geologic strata.
There doesn't seem to be any predictable "cycle" to it and it's never been associated with any cataclysm or mass extinction detectable in the fossil record.

That answer your question?

No, it means exactly one thing: the thing you're looking at has a yellow color.

There is no such thing.

>the thing you're looking at has a yellow color.
no, it means it either reflects yellow photons either green+red photons. this is scientifically proven.
>There is no such thing.
yes there is, I can literally detect them with scientific gear. you can detect individual photon energy levels.
you can deny science as much as you want schizo, it will never change reality. you have zero power over it, you must accept it or there will be consequences. just like you know not to jump from a bridge, because of the obvious consequences of that.
both yellow photons (~580nm) and green + red photons stimulate your eye cells the same, your brain cannot tell them apart, but they are different. you can never change this or prove otherwise.

that's an unfounded materialist assumption. Just because colour correlates with freauency doesn't mean it is determined by it. Colour is a qualia thst cannot be studied by empirically science

I was thinking more of peasant villagers than more educated classes. Math was just directly tied to their farm, not as some abstract theoretical field we see it as today. Acres, cartloads, stones, bushels, paces. Local agricultural units was basically what most of the world used as measurements before the metric system.

But yeah you're right more educated people like clergymen and merchants used bigger numbers & more complex math. But even for these educated people they had no Hindu-Arabic Numerals, no place value, no decimals, no systematic expressions, none of the stuff we teach to literal brain-rotted 8 year olds nowadays. Everything was written in words and math could be different in the same country, since there was no standardization back then. Mathematics was painfully slow and primitive before the Scientific Revolution.

Unironically this.
My first kiss was not so good because I was afraid of coming across too strongly, so I held back, and she dumped me the next day. Subsequently, I've just done what anon said, and all the girls said I was a good kisser lol.
There's no real technique to it, you just shove your tongue in there, move it around, then move it back and let her shove her tongue in your mouth and repeat the dance, progressively moving your hands around her body, feeling her up.

I have no time for the things I enjoy, I can not sleep at night, i am abusing drugs and falling deeper into schizoid behaviours. I am very probably clinically depressed. Had a nice woman i ejected from my life because i couldnt give a FUCK about the relationship

How do I get better at Math? I've always struggled with numbers and equations to the point I was placed in Special Ed for Math and it has absolutely crippled my self-esteem. Are there any practices or source recommendations to improve my poor skills?

no. you either get it or you don't and it's obvious you are retarded

>>16867205
Make sure you understand the fundamentals. It may feel bad to do it, but it may help to just go look at Khan Academy math catalog and just think to yourself how competent you are I. Each subject area. I personally did very well in high school but struggled in college call because my high school barely focused on trigonometry. You might just be missing a basic building block.
Then practice and take your time. It should feel intuitive.
It also depends on what your goals are. Are you just visiting this board because you know we do math here? Or are you hoping to be an engineer or something?

Perhaps most important is to consider your motivations. This place is full of insecure people who will do anything to feel smart. Some people are not cut out to be great engineers or scientists and that’s okay. I personally wasn’t great at math even though I wanted to be a physicist. I’m a lawyer now and am so glad I struggled because it put me on a better path. Consider your motivations.

Why is gimbal lock a problem? Why can't an object continue rotating through it?
9 replies omitted. Click here to view.
>>
>>16866577
Looking through this thread, you seem to think of it as some mechanical quirk. It’s not. It’s just mathematics. Think of it like this. Orbits have three angles determining their orientation. But if the orbital inclination is exactly zero, then the longitude of ascending node is completely undefined. There is no ascending node at all. You just supposedly lost a degree of freedom due to this singular behavior, but in reality it’s that Euler angles are shit like >>16866857
describes.
>>
>>16867614
The video linked by >>16866857 shows the plane being unable to rotate through gimbal lock.
I provided an example in the OP of an object rotating through gimbal lock.
Is the video mistaken, then?
>>
>>16867616
Again, you have this midwit perception of things being some kinds of sentient agents doing it on their own will. Its literally a fault in the description of a system, not the system itself being “unable” to do something.

>>16867627
Then why can't the plane continue rotating?

>>16867633
The plane isn’t fucking real, you mong. Do some actual math for once in your life, learn matrix multiplication.
