What are your thoughts on the future of cosmetic plastic surgeries?
For now plastic surgeries are kinda easy to spot but in the future they might be less obvious.

I think that every person that gets cosmetic plastic surgeries should have to have a government document with all the details of what they've done and of how they looked before with all the surgeries and photos documented.
And they should also have to let their partner see that document before intentionally having kids so they could approve on it. I wouldn't want my kids to have bad genes.

I hate plastic surgery because it fucks with evolution. Though, needing to detect it before breeding is a genetic trait that should be continued. But, it should only be used for accident victims who didn't get mangled from their own stupidity. Like from a meteor strike or something.

How do I remember go around from remembering these? I already remember the addition of angles formulas like sin(a+b)=sin(a)cos(b)+cos(a)sin(b). Can I use these to somehow formulate the sum to product and product to sum formulas?

>In the early sixties, Grothendieck visited Harvard while Zariski was still a faculty member. Once, while Zariski was lecturing in a seminar, Grothendieck kept asking him why he didn't prove his result for all schemes, not just varieties, but Zariski simply responded that it didn't work. Eventually, Grothendieck could stand it no longer and went to the blackboard and began writing down a proof for schemes. While he did so, Zariski wrote down a counter-example. When Grothendieck realized he was wrong, Zariski said (in his heavily accented Russo-Italian English) "In my time, I have had to learn many languages." At this, Grothendieck turned bright red from embarrassment.

>Another time Zariski was lecturing and Grothendieck again asked him why he didn't generalize his work to schemes. This time Zariski merely said "Now now Alexander, we must show some self control."

>In a discussion with Grothendieck, Messing mentioned the formula expressing the integral of exp(-x2) in terms of pi, which is proved in every calculus course. Not only did Grothendieck not know the formula, but he thought that he had never seen it in his life.

Why do brainlets pretend that brain surgery is a complicated matter? You have two common saying to emphasize the ease of a task relative to another, "It's not rocket science," and "It's not brain surgery." Why do people think these two things are comparable in difficulty? A brain surgeon is basically a just glorified butcher.

The best of best of Medical School.

Which were before the best students from Biology & Chemistry.

Surgery itself is more manual dexterity than mental power. Surgery is a Physical Body Skill like Sports, Drawing or Music.

Medicine & Biology are more about Memorizing a Lot of Stuff

Instead of the Logical Reasoning required in Math, Physics & Engineering (to varying degrees)

Brain Surgery is very simple if compared to Physics. Just cut some damaged parts of Brain without killing the Patient, & hope than the Brain heal himself.

Physics, Math, Engineering PhD is much harder than Medicine.

Physics, Math & Engineering PhD are harder, however get paid less than Medical Doctors.

I was using my pi cluster to brute force tripcodes and came across something interesting.

I found a series of roughly 100 numerically sequential passwords, all of which encrypt to the same exact tripe code (which has Trump's name in it no less).

tripcodes are generated using DES encryption.

mathfags, im genuinely curious.

there are 303305489096114176 unique total possibilities for a tripcode (a-z+A-Z+0-9 = 56 characters ^ 10)

the odds of this occuring must be astronomical. can anyone confirm?

Full list:
https://pastebin.com/ERw6RMFz

#43:"A encrypts to trip AtRUMPi5R2
#43:"B encrypts to trip AtRUMPi5R2
#43:"C encrypts to trip AtRUMPi5R2
#43:"D encrypts to trip AtRUMPi5R2

#43:"X encrypts to trip AtRUMPi5R2
#43:"Y encrypts to trip AtRUMPi5R2
#43:"Z encrypts to trip AtRUMPi5R2

you get the idea...

Try any one of those as your trip. they all encrypt to the same exact phrase.

The odds of this must be astronomical

Geometry problem I generated. Help would be greatly appreciated.

Two lines originate from the same point A and run at a given angle (theta) continuously away from each other. A third line, AG, originates from the same point at half the given angle, and perpendicular to it run lines BB', CC', DD', etc. These lines are bisected by AG. All polygons formed inside the original two lines AF and AF' must have area x.

My goal is to describe this pattern in which the triangle and descending trapezoids share the same area x. I want to do this by finding some equation that scales the original height, h, generating the next polygon height in the sequence.

/sci/, my new housemate believes in nearly every hoax and conspiracy theory you care to mention.

>flat earth
>installing smart meters to monitor your water causes you to stay awake because of the "pulsings" emitted
>having any sort of electronics on at night disturbs sleep

He even showed me a video of a "professor" lecturing about deciphering alien code with "binary blue" and "binary red" with 3 codes embedded.

Have any of you had to deal with this? Is there a way to convince him or should I just avoid him?

I've heard good things about gallium and its ability to break down some metals, and I want to use it for a project.
Can I corrode raw bronze with gallium?
And if I diluted the gallium into a liquid, would that dilution still retain some corrosive properties? If so, what would be a good thing to dilute it in?
Don't worry I swear it's all legal

Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion.


if you want it to dissolve into a liquid you'll need to mix it with urea

>>8998401
So just a gallium/urea mix? Or gallium +urea and then put it in another liquid?

gallium urea mix would be fine
