Where is a place on the internet that I can learn physics. I am trying my best, and Im barely pulling a C+ in the class...on the curve by 1.3x I have never done something like physics, give me calculus I can solve anything for you, but holy hell I don't like physics It's too much spatial analyses for me.
HOW ABOUT READING YOUR FUCKING TEXTBOOK

i didnt buy it
How challenging was physics for some of you at least tell me that much?
I'm taking both classes next semester, and while I'm planning on studying both, which is the tougher course? Should I study more for one than the other?
Real analysis if you are taking both at the same level.
>>8974478
Learn linear algebra before abstract algebra
Learn topology before real analysis
real analysis is a troll course: "hey let's waste 3 months doing a bunch of shit with epsilon and deltas and a bunch of lemmas, then 1 week before the course ends: "oh btw in topology you can just define a metric and all this shit we talked about can be done with a metric and you don't need to worry about continuity just check inverse function of open is open lol!"
Things just pop into existence. Order is the state of things.

Well don't I already know how? The time I've invested in this though.

If homo sapiens had died out for any reason thousands of years ago, leaving neanderthals as the dominant species on earth, would they have become advanced as we are?
>>8972433
Also, would they have been more peaceful or violent than we are, or about the same?
>>8972433
No since they had man boobs.
No.... go back to /pol/ Neadnerthals were less advanced than humans. They never developed advanced tools that humans did, and did not produce as many cultural artifacts as humans, and the large majority that are neanderthal are from after human migration into europe. There is only one cave painting attributed to neanderthals, and it's some fucking hand prints on the walls. During the same time, humans were making intricate cave paintings of humans, animals and rituals.

is University of Rochester actually the best university to go to for MS/PhD if I want a career in optics or is it just a meme? Many say that it is the best for optics, but would a MS/PhD in EE with a focus on optics/photonics at a top school like UMich get me the same or better opportunities?
Is a BC CS with a minor in robotics from an Ivy good enough if I want to work in industrial automaton?
Is there anything like Tails with Tor and everything, just for Raspberry Pi?
Does /sci/ consider psychology a science? Why do you / why not?
I'm an social psychologist, and what I do is basically measure human behavior in accordance with the scientific method
I know that the stigma of psychology basically boils down to facebook posts saying "if a friendship lasts more than 7 years, it will last a lifetime" or other related spiritual bullshit. So it's pretty understandable that people toss it in the thrash right next to astrology
However, allow me to explain one of my personal favorite experiments to demonstrate what social psychology is
If you want to look it up, it's from Loftus and Palmer (1974)
People were shown a video of 2 cars crashing. It's short. 2 cars crash, some debris flies around and that's it. Participants were then divided into 5 groups. One week after the video was shown, participants were asked to recall certain aspects of the video. Specifically, they were asked if they remembered there to be broken glass in the video of the 2 cars crashing into each other (there was none). They also asked participants to report the estimated speed of the 2 cars
For each of the 5 groups, the researchers used different phrasings of the question. "Did you see any broken glass when they/how fast were the 2 cars driving when they" smashed (1) /collided (2) /bumped (3) /hit (4) /contacted (5) each other?
And lo and behold, people reported there to be far more glass when the experimenter used the word "smashed". The mean estimated speed was a lot higher as well when the word "smashing" was used (40.8mph) versus when the word "contacted" was used (31.8mph)
What does this tell us? Memory is a very malleable thing; things as simple as the phrasing of a question can affect someone's recollection of there being broken glass, or the speed of a car. Eyewitness reports, for example, can depend heavily on the phrasing of the investigator
How is this not a measurable, valid scientific field? Please discuss /sci/, I'm curious about your opinion
I got some more of my favorite experiments if someone's interested
there's some psychology that follows the scientific method, there's a lot that doesn't
things get especially hairy when self-reporting is involved in data collection
>>8967293
self reporting is somewhat of a hairy topic indeed
on one hand, it's fucking self report
on the other, if there are clear cut differences in self report, what other conclusion is there left to draw that the designed manipulation was the determining factor involved?
Why does the Pythagorean theorem work? I know the proof representing the squares geometrically, but why do the squares of the two legs equal the area of the square of the hypotenuse? It just seems like magic to me. I can't register any intuition for it.
>>8966217
it's just the way it is, don't question it. just like earth being a ball

It's just the formalism we've chosen. We are lucky to have so many nice properties from a handful of axioms and definitions.
NASA just selected their newest Astronaut Candidates. These guys are incredible. Check out their bios.

They all look to be very well qualified, I wish them the best.
Strange to think it's possible that one of the first people on mars may be in that group.

Will be at least 20 more years until a manned Mars mission

Holy fuck.
pic related, it's pissing me off like mad
its just pythagoras in disguise, do you have a problem with pythagoras?
>>8975161
Wouldn't it say "|r|" or something then. because you get the hypotenuse not the whole nummber
>>8975164
PS
|Z|=sqrt(z^2) = sqrt((a+bi)^2)
not
sqrt(a^2+b^2)
Is he right?
No because the aliums don't know earth is 6 thousand years old because they don't have Yahweh
>>8974338
No because the cosmic microwave background is a local phenomenon caused by excitation of diffuse gas in on the "edge" of the solar system.
this excitation comes from the transgalactic micro currents that connect all charged bodies in the cosmos

Undergo hormone replacement therapy, have two mastectomys and have gential reassignment surgery, so you can at least look like the master gender.
Chances are you'll probably just end up looking like a sad dyke long term, so it's up to you.
Unfortunately, you won't be able to get chromosome reassignment therapy, so you'll be stuck with subpar IQ and physical strength.
Why would they fall towards each other at the same rate?
This makes no sense.

[math] F= ma = mg \implies a = g [/math] Acceleration due to gravity is independent of mass.
>>8974297
>not using [math] F_g=G\frac{m_1m_2}{r^2}[/math]
>>8974297
Your math code isn't showing up but if F = ma, m = mass so wouldn't that increase?
Also why would gravity be different on other planetary bodies but the same on earth? Makes no sense
