Why are black and white people considered to be of the same species, whereas dogs and wolves are considered to be of different species?
>taxonomy
Not science.
https://en.wikipedia.org/wiki/Wolfdog
>Wolf and dogs are interbreedable
>it's not even one-way, meaning male dog-female wolf gives the same result as female dog-make wolf
>biologists still say they're two different species despite the facts contradicting the definition of a species
I guess biofags are just retarded.

I guess that also explains why rafflesia arnoldi is considered a flowering plant even though it has literally no characteristics of a flowering plant
>tfw your learning algorithm is stuck at a local minimum
How do I convince myself to stop browsing then internet and interact with real people instead?
>>8544772
What? Is this some sort of autism-speak?
Try warming up your body, drinking water and stuff.
>>8544772
Explain more about the algorithm

>stuck at a local minimum
I'm not sure what's wrong with your head but better that than heading off towards a global minimum
is it possible to inject and lock a Laser?
>>8544505
Injection locking is a thing, if that's what you're asking.
>>8544505
Energy loss due to heat
>>8544505
Mirrors aren't perfect. Current record for number of laser bounces is likr 1000 though for a precisely aligned cavity.
I'm working in a project for college and I really need to transform the following equation to make h the variable, as a function of x. Can anyone do this? I'm having trouble because it's not linear.
h = r1 * sin(x) + r2 * sin(2 * x) + r3 * sin(3 * x) + r4 * sin(4 * x) + r5 * sin(5 * x)
x(h) = ?
it's a periodic function so you'll have to take a restriction to make it injective.
are the r1. r2 etc constants?
x belongs to ]0; pi/2[ and r1, r2, etc. are constants, yes.
Use Euler's formula and write the sine terms as complex exponentials, use law of exponents and make a change of variable. It'll really make you think.
How deep would you have to dig to go back 100years?
I know it depends on the terrain and soil but in general.
Would 1ft be like 5years?
No one knows?
Has your yard gotten a foot of dirt in the past 5 years?
>>8543940
About an inch below the surface. That's how long it takes dirt to be made.

Why is penmanship not a thing that's taught in school anymore? I find it really pathetic when I see someone who is 15 or older have garbage penmanship. You print about as good as a kindergartener.
Can someone explain why the fundamental theorem of calculus works? I understand how to utilize the theorems, and I understand why one would subtract the function at interval point B from A. My question is why does finding the anti-derivatives give the area under the derivative function?
>>8543772
The derivative is the rate of change, the integral is the accumulative effect. If you have an equation for the speed at which an object is moving, taking the integral will give you the total distance covered.
Why does calculus do this? Because that's what is was designed to do.
>>8543772
Sit tight, I need latex to prove it and explain intuitively why each step works
I'm looking for a good book which explains the fundamental laws of physics in depth. Stuff like conservation of energy and mass, electromagnetism, newton's laws, and even more advanced stuff like einstein's theory of relativity, the Michelson Morley experiment, etc. I'm looking for something that explains the serious science behind it in detail, not books that just mention the experiment, how it was conducted, and the results, I want a deep scientific understanding.

University Physics by Young and Freedman
An Introduction to Mechanics by Keppler
>>8543688
Damn I would buy these all right now if they weren't so expensive. I guess I'll have to settle for pdf formats and read them on my ipad or kindle.

The Road to Reality by Penrose?
Sup /sci/. I'm a Math major going to a 50-80th ranked state university In The United States of America. I'm a junior RN and I'm working with a professor, hopefully getting a paper published before the end of the year(with me as the only co-author). I want to go to a top 30 school for mathematics. What else do I need to do in order to be competitive? I plan on applying for the spring semester so my senior year counts for something. I'm not really a "prodigy", I failed a few math classes in HS; however, I really straightened myself up in college and have a GPA of 3.96. Fuck, do I even stand a chance, or am I just gonna be another pleb doing a PHD in triple integrals at small town college USA.
>>8543397
No you are going to be stuck with your PhD teaching basic calculus in a small town high school

>if you combine both fractions
What the shit kind of wording is that for a problem?
Either:
1) If you combine both classes, what fraction of the students prefer shit over fuckshit.
or
2) If you add both fractions, what fraction do you get
I guess this is what the Yale people meant when they say "this is not an intellectual space". School has never been an intellectual space in america it seems.
>>8542509
how the fuck are you suppose to find the answer to this if your not given the number of students in each class?

Those who can, do
those who can't, teach.

Is eugenics a pseudoscience or does society just want us all think that so we don't pursue it?
>>8542397
Eugenics is not considered a pseudoscience, it's considered immoral because it hurts peoples' fee-fees.
Eugenics is objectively true and works on all animals that it's been tried on, including humans. All modern farm animals, modern crops, and a majority of pets are the result of eugenics. China has had successful human eugenics programs.
>>8542397
Eugenics is already in effect myfriend.
Its called natural selection.
By being without official eugenics we can have commodities like 4chan and ugly ppl.
One day all of it may change.
Red pill me on Aubrey de Grey. Is he full of shit or will he actually reverse aging in 20-30 years?
Doubtful. It's not exactly an easy problem, and he doesn't have proper funding.
