Can I even live decently if I go for a physics degree unless I get a job in an institute of CERN's magnitude which is near to impossible unless you're a fucking genius?

Just go work for a physics factory when you graduate.

Hey /sci/
I'm going to try Modalert (Modafinil 200mg) tomorrow morning for the first time. My aim is to catch up on some missed maths work over the course of the day.
Any of you have any experiences with this stuff? I understand not to seek the effects but rather to let it work in the background. Would it be a good idea to take something like this in an exam?
Dont take the full pill, cut it in half. Otherwise you'll get all spacey.
Expect your pee to be bright yellow and smell like sulfur, and to be in a very trance like state.
That's about it

Damn, I bought this stuff to help study, not to talk to aliens and become a chemical factory.
Also just found theres another thread. Deleting this in a bit

Don't take 5 in one day.
Does anyone here have completely scientifically illiterate parents? I'm studying physics, and my parents are pretty religious, and in the spiritual corner (homeopathy, opposing vaccines, etc...) Today I was dragged into a homeopathy discussion with them for the umpteenth time. As always, I tried to explain to them that from the scientific side, it has no basis at all, but they just tell me something along the lines of "you can't measure everything, how can you measure the love from a mother to her child, yadah yadah", completely resistant to any kind of scientific...

Common ground is a good way to go. I mean she's not entirely wrong, the homeopathic side to medication is quite important. Support, love and attention are important matters in recovery, as is anything else that makes the patient feel "good" and be more motivated to getting better.
However, the body isn't infallible in it's recovery. That's the point that you have to explain to them, and note that a combination of the two treatment types is the best option.
This isn't your personal blog site,no one wants to hear about the fedora tier arguments with your parents.
My advice would be to get off of your high horse. If there is one thing that science can prove, it's that humans are extremely gullible. They are humans the same as you. All the only difference between medicine and homeopathy is that one holds off death longer. Either way it will fail you in the end.
How effective are aluminum foil hats really?
Not trying to meme here. From a scientific point of view, can aluminum foil really protect your brain from radiation? From which kind of radiation and how much foil would I need? What are more effective alternatives?
Thin sheet of aluminium foil will reflect radio waves but not radiation. Only multiple coated leads can stop hazardous radiation.

And unless you cover your entire body in aluminum foil, it'll actually bounce radio waves inside of your head.
Is there any credible scientists that actually believe intelligence is 100% evenly distributed thought races, or any other trait for that matter?
> 100% evenly distributed thought races
No. wtf ofcourse not
>>7954062
this what some people actually believe tho
>>7954066
So what ? Retards will believe in anything.
Do you really think God exists and he made all men equal ? Completely throwing out the fact that evolution treated everyone differently ?
What's the deal with the "logical" or "intelligent" side of thinking being reserved by personalities claimed to be isolated, antisocial, and/or hermit-like?
My psych 101 class just finished a personality unit and it was hammered into our minds that "antisocial people are almost inherently more logical, whereas more bubbly, social people are are less logical and rely on emotional reasoning."
I went to a leadership conference as well that taught us to divide people in leadership four ways, two of which were the contrasting "social...

People forgo reason to be liked. Look at secularists, instead of them arguing against the irrationality of faith they adopt this bullshit co-exist bullshit to avoid conflict.
Math grad here, doing pretty well.
This year I tried to go hermit mode (no roommate, go home after class/work) and I thought it worked pretty well. I am fairly introverted and I don't really like to have people in my place when I don't want them there. That being said, I'm particularly antisocial, I do enjoy talking to people, parties (if I have friends with me) etc. I just don't like having people at home all the time.
I don't think the other people who came in the same year as I did are particularly antisocial either.
Many are somewhat introverted...

Jeez you seem like a butthurt social butterfly.
Anyway what leadership workshop is this, that seems strange there are plenty of antisocial folks that are just idiots.
If we breath in oxygen and breath out carbon dioxide why don't we die when we fall asleep?
Wouldn't the room be filled with carbon dioxide?
>>7953894
>Wouldn't the room be filled with carbon dioxide?
It would be if it was airtight, yes. But it's not.
>>7953894
You breath in oxygen and carbon dioxide, you breath out slightly less oxygen and slightly more carbon dioxide.
>>7953894
If you sleep with a plastic bag over you head, you might die. But a whole fucking room is just too big and contains too much oxygen.
Okay /sci/ I'm done.

Thats theoretical physics for you
>>7953875
is there any other experimental evidence of dark matter besides "the observed mass of the universe doesn't add up to our calculations so there must be dark matter"?
It's not as crazy as MOND.
There is other evidence for dark matter:

Has anyone in /sci/ been to a conference/expose in your field? If so, how rewarding was it, in terms of information, connections and the like? Was it worth it? If so, how often do you go? What is your field? Did you go as a group or did you go alone solely for professional and academic development?
Pic related is my first professional conference I'll be attending.
shameless self bump.
>>7953825
No idea,
But it's definitely worth more than this website.
>>7953857
well, that's a given.
Hey /sci/,
I'm taking a statistics class right now and I really miss the "puzzle" aspect of algebra and calculus. I have never actually taken a calculus class and I'm wondering how hard it would be to teach myself calculus...perhaps just to the extent of a high school calculus class for now.
I'm starting from scratch and am just reading about the "hot topics" that I've always heard people complain about. Right now I'm reading and taking notes on Derivatives but I'm pretty sure this is way out of context to me as I'm...

you have two options:
do you want to start at to VERY beginning and work to calculus?
do you want to learn about limits / derivatives / integrals (most of HS calc) intuitively and not formally?
if you answer yes to the first one, first understand logical connectives (implies, iff, and, or, not) and quantifiers (universal and existential) to begin being able to write logical sentences about math, and learn about fundamental analysis concepts from the ground up (sequences, convergence, Cauchy sequences, subsequences) then you can define things like limits...

what I did in high school was I watched the MIT open courseware 18.01 videos taught by Professor Jerison. Those videos are pretty fucking great and easy to follow along to. I also had a cheap copy of Stewart Calculus which I bought used for like $5 at a half price books. I did a lot of exercises out of there after watching the corresponding MIT lesson, as if I were actually taking the class. It worked ok for me imo.
OP I taught myself Calculus using the free website "Paul's Online Math Notes".
It is by far the best resource I can think of for this. Simply read the lesson, take notes on it all into your notebook, and then do the practice problems.
Here: http://tutorial.math.lamar.edu/
If you do that you will know calculus more than well enough to use in any other course that requires calculus.
Now if you REALLY want to understand calculus, you should read calculus textbooks. Not just ones that are designed for, say, engineers, which only cover the...

Hey guise I just wanted to say that I only have a BA in engineering but I'm an expert in climate science and cosmology

Is that true? Ima look that shit up senpai.

No wonder most of what he says is B.S.

He didn't believe in anthropomorphic climate change till he got scolded on it.
i have noticed something odd over the past 2 years. it seems bees (large carpenter bees) are working with hornets and wasps
i know it sounds crazy . my back yard is kinda big. and spring and summer seeing them isnt uncommon. its a constant while its day time
but these past 2 years when i kill a carpenter bee
(i do it because they make holes in wood and i would rather it not be my house they tear into. i only do it when they try to make holes in stuff to close to the house)
anyways when i kill a carpenter bee a hirnet or wasp always flys by about...

Get psychiatric help
Not really. Bees are smart fuckers and they constantly coordinate. I doubt about the wasps though. Not that they aren't smart, but they don't give a shit about bees and usually attack them. They don't make honey either so they got no stake in protecting bee flocks.
Still, it might be a general bee territory and a dead bee might be triggering the fellow antenna fuckers. You should just get about 5-10 chameleons and place them around the strategic corners. They go through bee and hornets like butter.
>>7953768
Your last paragraph greatly discredited your validity, so let me rephrase your post.
>Bees, wasps, and hornets have interactions
>Such interactions are possible social communications between the species
>A communiction means a bond between to subjects.

I'm not sure if this is completely /sci/ or not. I don't consider management science to be worthwhile but I think this is interesting to think about.
If Chinese people are made to work in an extremely hard working way (their Gaokao end of high school exams require crushingly high amounts of study that we'd consider child abuse and make the SAT / A levels look easy as shit), and there are so many of them, then why don't they have a monopoly on... anything?

Chinese people like other Asians simply don't care about discovery. They prefer to use what humanity knows now and apply it to satisfying their technological needs and that's pretty much it.

What should i change my major to? Im a jack of all trades when it comes to maths and sciences.
I just want to be finantially secure and independant.

Psychiatry or other field of medicine. It pays very, very well.

If only i could get into med school now..
>>7953610
It's all about memorization. I used to be very bad at it, but then I learned what the method of Loci and spaced repetition are.
https://en.wikipedia.org/wiki/Method_of_loci
https://en.wikipedia.org/wiki/Spaced_repetition
https://en.wikipedia.org/wiki/Mnemonic
Google mnemonics for med school too.
You can easily get in med school if you have average intelligence and can memorize more or less well.
