Suppose Schrödinger's sends you one of his mystery boxes in the mail. When you open it and the cat is dead, did you kill it?
>>8164437
My consciousness collapsed its wave function
if 1000 Schrödinger boxes are created with a camera inside and 1000 are opened after a day, which will have less dead cats?
>>8164437
No, the cat suffocated from lack of oxygen
is jonathan katz right /sci/?

>what you should be doing
(have a goal in mind) -> (does that goal need phD) -> yes -> (get phD)
>what people do
(I have no clue what to do in life) -> stay in school forever -> blame it on school
School isnt the problem. If it isnt school, itll be singing. If it isnt singing, itll be the next big DJ, etc.
The problem is people having no specific goal, and only a vague general idea of success

His phrase is pretty biased though. He is in academia.
A drug seller would say that he knows more people whose lives have been ruined by drugs then by getting a PhD...
That statement literally means nothing. That said, it is not true that people with even minor talent blindly follow graduate school because they didn't have a job lined up immediately after university and just don't want to go around for it.
(study something you really love) -> get PhD in it -> (get whatever job with it to pay the bills and keep studying it because you love it)
If we ask of any knowledge: "How do I know that it's true?", we may provide proof; yet that same question can be asked of the proof, and any subsequent proof. Therefore we have only three options when providing proof in this situation:
>The circular argument, in which theory and proof support each other (i.e. we repeat ourselves at some point)
>The regressive argument, in which each proof requires a further proof, ad infinitum (i.e. we just keep giving proofs, presumably forever)
>The...

What is 'fundamentally weak' about the regressive argument?
>>8164361
Cant know nuffin. Just do what science does and take observed reality as your axiom, at least its consistent and historically productive
Intellectual conversation on biology

Someone explain how diindolylmethane removes epigenetic NRF2 blocks and helps to regulate your immune system.
How long until we figure out teleportation?
Is it even possible?
even if we could transfer and replicate with 100% accuracy the entire atomic makeup of your body, there's still the unknown problem of whether or not 'you' will still exist in the teleported body
who would want to be teleported if it's no different than dying?
teleportation is theoretically possible, but it's several thousand years away (assuming steady human technological progress, which probably won't happen)

Im pretty sure it kills you, so i would never do it
I work at a Lowe's in Alabama and once had a customer claim that the second law of thermodynamics proves that evolution can't be true because entropy over time can never decrease. Anyone else care to share the worst scientific arguments people have made?
>>8164289
>claim that the second law of thermodynamics proves that evolution can't be true because entropy over time can never decrease.
I read in some book recently that this argument had been used by creationists in the past. What a coincidence.
>>8164292
I know it's false but I don't know enough about thermodynamics for the detailed explanation of why it is incorrect. Anyone care to explain in detail?
>>8164292
Also, isn't it fucking hilarious how creationists pick and chose when they believe in science?
I never took chemistry in HS & I've been thinking of returning to college.
How do I start studying chemistry to do well in my placement exams?
>>8164282
This is a pretty good book for general chemistry.
http://bookzz.org/book/1203060/3a549a
here's the solutions manual
http://bookzz.org/book/2082734/441329
yeah, the text is 6th, the solutions 5th, it doesn't really matter, and you can dig around on bookzz to try to find ones that match if you really give a shit
definitely a noble cause, wish you luck on your endeavors and hope you get a great career!
>>8164282
I'd recommend signing up on edx.org. It's an opencourse site with a strong focus on stem. it's all self-paced and there's plenty of courses with varying levels. It's not dodgy shit either.
How come you can almost find nothing about the chemical structure of Zyklon B on the internet?
There's basically no scientific literature on it.
The thing which apparently killed "6 million" has no good proof of being a usable WMD.

>Solid that reacts with water to produce Hydrogen cyanide
Figure it out yourself, why are you on a science/ math board if you're too lazy to solve a scientific reasoning problem?
>>8164277
Isn't Zyklon B just HCN?
>>8164297
It was a solid pellet that produced HCN upon reacting with H2O.
>everyone around me thinks Geometry is harder than Algebra
Why?
>>8164183
Does it count if I haven't gotten to differential geometry but I can definitively say babby geometry is easier than babby algebra, despite how fucking easy babby algebra is?
>People on this board think Geometry is the nearly 2000 year old shit they learned in middle school
>They think algebra is solving real polynomials
Why does this fucking board even exist. At least whenever I see fedora tier discussion like this I remember to go back to MSE, MO

They are the same subject.
Is this what women in STEM are like?
https://www.youtube.com/watch?v=OgL3962XyTY
What?
>>8163955
Just wondering if the average female mathematician really is like this.
>>8163953
No, that is one woman in stem though. Get a couple of hundred thousands more and then their combined personality traits will be what 'women in stem are like'.
That said, I do not understand how she defined her goal as being a mathematician.
Like, I'm a reserved and chill dude. I do not even know of the existence of any of these types of game shows but she's watched whole seasons of it. How do people like that end up wanting to be mathematicians?
She is literally a basic bitch....

What light bulb best simulates sunlight?
the one you posted.
>>8163932
They're called "daylight" lightbulbs and give off a 4700K black body radiation profile. They're extremely common. Go to Home Depot or anywhere else that sells lightbulbs and buy some.*
*the reason why a lot of people don't like them is that similarity to natural sunlight disrupts their circadian rhythm and makes it difficult to sleep
>>8163944
Sure, but we don't even know what it is. What is one we could buy in stores?
Can we agree on this:
Astrology: empirical knowledge gathered through generations about empirical observations on patterns people that was born in a date share, obviously using heavy cognitive bias.
Magic: Auto hypnosis and heavy cognitive bias that uses the placebo effect to produce medical miracles.
God: Imaginary being that a society or group of people tend to use for certain benefits, it's powers are derived of cognitive bias and my previous definition of magic, obviusly following social patterns and mob rule, also God's visions and profets...

> Acting like it is ´original thought´ and that you're a ground-breaking genius.
It took you this long to realise these overt things? Gosh, you're slow.
>>8163936
nope, just wanted to make a thread about it.
wanna talk about it?
>>8163920
Well, how do you then explain how people who were extremely good at evading cognitive bias still believed in God, such as people like Saul Kripke or Albert Einstein? I mean, for example, the extend of objectivity with which Einstein went in proving general relativity and in Einstein-Bohr debates is mind-boggling, and "Naming and Necessity" is perhaps the best argumented book of 20th century, yet both believed in "derived from cognitive biases" God.
Would you also state that bias evasion is as...

How do I get good at math /sci/?
What're the best sites/books?
>>8163533
khanacademy.com

>khanacademy.com
Sorry, it's khanacademy.org, start here: https://www.khanacademy.org/math
It depends. What level are we talking about?
Why do you want to learn? Is it anything specific to your career or do you just look for general knowledge?
I'll see Multivariable Calculus. Any books to recommend me?.
