Everybody thinks that I'm boring. Many people think I've got no clue.
If astrology isn't real, how come Nostradamus predicted the future?
We should study more about astrology imo
>>8263786
Such as?
>>8263786
He didn't use astrology. The human mind is metaphysical and can sometimes cheat.
>>8264753
The French revolution, Napoleon's and Hitler's rise, the Great Fire of London, the assassination of the Kennedy brothers, 9/11, the rise of ISIS, etc.
Is being gay a genetic thing or am I a sinner and going to hell?
>>8263778
Being gay is not genetic or natural at all, it's a manifestation of the evil inside you. Disgusting!
>>8263778
Being gay is not genetic, luckily there's no such thing as hell either. Enjoy your life faggot.
Being gay is ultimately wrong, even heterosexuals get more anal sex than geys...
Is the ballmer peak real?
Yes.
Is there any real science to back up the claim.
Do they realize you can download and print them?
I love books. Were they 10 € each a lot more people would buy them.
Were do you find expensive books like Reed - Simon for a reasonable price?
>>8263738
>US prices
literally my textbooks in the UK are like, 30 pounds, and that's if I wanna buy them. I get them from my college library for free
>look up same textbooks on Amazon US
>$300 per book
>muh free market capitalism
>>8263738
>buying textbooks, ever
Even if you don't have access to a library, there are plenty of ways to steal them.

>Even if you don't have access to a library, there are plenty of ways to steal them.
What are you even talking about?
You get fucked if you take away a book from a library without first checking.
It's basically theft.
What is between the lines? Is it silence?
the exact inbetween would be antinodes which aren't silent because it's the minimum amplitude. inbetween those would then be silence.
>>8263718
so there is no region with absolute zero oscilations of medium, just high and low regions, making sound wave continuous just like EM . Is this correct?
>>8263722
no, i'm saying there is a zero, it's just inbetween the node and antinode. having a wave where it's minimum is zero means its maximum is zero, which means its flat, which means there's no sound to begin with. if you are talking about a case where there is clearly a positive maximum then the only place where silence can exist is in-between the max and min since they cancel themselves out.
So \sci\, is mass a vector or not?
It's a 2-tensor
>>8263671
mass times velocity is
/sci/ what would be the limiting factors for
1.taking a 3D printer
2. replacing the head with an electron beam emitter
3.house it in an autoclave (control pressure/temperature)
4.run a metal of your choice in filament form
5. extrude it and retain its strength and ductility with the autoclave
6.?????????
7.additive manufacturing of metal parts
am i missing anything here?
Whats the filament made of ? The nozzle shouldn't melt with the filament itself, considering they are both metals. And even copper nozzles are difficult to open a nozzle hole with laser cutting.
Are electron beams enough to melt the metal instantly ? I'm not sure how it would work. Also it should cool immediately when it comes out of it.
>>8263645
well i wouldn't want it to cool on the spot because that would cause it to shrink really fast and weaken the altrope structure right? sorry my chemistry and physics is rusty.
>>8263655
Then the surface quality will be shit. thats the problem with cheap printers, the filament doesn't stick to the layer beneath and shift a tiny millimeter, then the layer above doesn't fit right on top the previous layer and cause stepping artifacts.
Metals cool really fast but they would require very high temperatures to melt through the nozzle first. I don't know what kind of system can provide that level of quick heat control.
Why is the lobster blue?
crustacyanin?
because of his immunity to frost damage.

Is there a preferred direction for spinning around the sun? I thought it was random
Hey, /sci/.
I'm a guy who followed almost every rule in academia and ended up with a PhD in CompSci. I've not revolutionised the field at all, obviously, but I did get some good points across, some new results that mostly sprung out of other techniques and barely some intuition on my part.
I've been a lazy git all my life, my mother used to wake me up to teach me letters and couldn't have done half the things I did without being pushed. In the end though, I did end up with a desire to actually do something about some of the open problems.
Do you have any questions for me? About CompSci or in general, anything.
>Do you have any questions for a nobody?
Nope
>>8263487
/sci/ hates compsci
/sci/ only cares about math and physics
>>8263487
just call your thread an AMA you autist
I study physics and genetics obviously isn't my forté, so could someone with knowledge of genetics explain CRISPR to me, along with its pros and cons?
http://www.stuffyoushouldknow.com/podcasts/how-gene-editing-works/
A little popsci-ish, but not a bad overview.
>>8263462
Thank you.
How do you do this for every single cell?
if some male twins marry female twins.
will their offspring will be cousins or brothers?
>>8263367
>semantics
>>8263409
answer it.
I demand to know.
>>8263409
Semantics are meant to map roughly to underlying mechanical truths. So yes, child, it's semantics.
Well, smart alecs - which is it?
16/2
>>8263365
Neither, it's 4√2
>>8263365
2V(2) * 4 V(2) is exactly the same as V(2)*V(2)*4*2 = 16
divide by 2 and you have 8
Have you ever heard about Neuro-linguistic programming(NLP)? Your body contains 8 Chakras. These are instinct, or power in your body. Drugs can stimulate those different "Chakras". If one Chakras is low, you will get negative consequences. Like if your 5. Chakra is low, thats the sosial part of the Chakra. Guess witch drug that simulate that Chakra? MDMA, and that drug is also known for developing of Sosical skills.
Why do I think this has to do something with the drug restriction?
In 1970 The USA discovered (NLP), but the same year did USA restrict drugs.
(https://en.wikipedia.org/wiki/Comprehensive_Drug_Abuse_Prevention_and_Control_Act_of_1970)
https://en.wikipedia.org/wiki/Neuro-linguistic_programming
There is hard to find any information about drugs and NLP, but if you study NLP you learn that it does. At the moment there is a Norwegain wikipedia page that tells about witch drug that stimulates witch Chakra.
Heres the Norwegian Wiki page about it. Use google translate to translate it:

good thread OP
anyone got more rolling paper ?
>>8263360
>MDMA used to develop social skills?
when on drug the social dynamic doesn't really matter
from the coked up jabber jaw
to the loudmouth drunkard
to the meth head taking a toke at 4:00 am at a bus stop
to the heroin addict shooting up in a ditch.
you just become unaware of the social dynamic.
>>8263373
Before I tried MDMA my social skills was = 0
After 3 rolls, I developed a manipulate social skill. Meaning I know what to do and say, in 2 different ways, to make people feel better, or harm them people in a negative way by knowing what that persons weaknesses. I have a social skill now that can make people do things for me, because i
convince them to it. I have always wondered why I got "Fixed". But if NLP is a thing, I have finnaly fount out why.
LSD made me get many flashbacks, and all I could think of was why Drugs are illegal. After alot of research I think NLP in fact have something to do with drug restriction
