I'd recommend Einstein's "Relativity". If you're completely unfamiliar with the basics of the Theory of Relativity then I'd say its a bit terse. However, if you've had some previous exposure it's a great quick read that gives Einstein's own perspective on the "derivation" and "implications" of relativity, in a fairly nonmathematical perspective (some math is discussed, but anything beyond basic algebra isn't used).

This isn't the most "popsci"-ish book, but you're on /sci/ and frankly I'm surprised nobody has flammed the shit out of you for even mentioning popsci.

>popsci
>pro: introduces youth to scientific thinking
>con: gives adults just enough knowledge for them to think they know everything, and end up hurting society by having idiots spout misinterpretations and oversimplifications

I was looking more for something about astronomical objects. Not for education purposes clearly, just fun reading.

>>8062852
Oh I see. I'm not too familiar with that, but sometimes when I want some background noise while working I put on Neil Degrasse Tyson talks I find on youtube. I realize this isn't what you wanted, but maybe it'd interest you the same (if you haven't already exhausted this).

>>8062620
Astrophysics major in undergrad? The more you know.
Anyway, you'd want a solid physics and math foundation for that, I guess.
To that end, consider the sticky.

>>8062620

whats the highest math you've taken? Physics?


>> Just graduated with astrophysics degree

>>8062632
Well, I meant I plan on majoring in astrophysics after my undergrad of course

>>8062637
Up to Calculus, and I took AP physics

What did you cover during classes? Hardest parts? Sorry for so many questions, I'm just intent on this career

social cohesion via shared cultural artifacts

None. Unless it's weeb music desu

>>8062440
Is that supposed to be difficult?

>>8062447
for kids like OP, yeah

F = kx
Fc = (mv^2)/r

Wow 2 equations op so hard

Also, is the "most research is useless" meme true for sciences?

>>8062412
Most academic research is "useless" in that it lacks either a direct or immediate payout. This is not to say that it shouldn't be done as blue skies research is what generally leads to significant advances, but such advances are neither quick nor dramatic the majority of the time. This need for long term support makes such efforts a generally poor target for industrial support which is driven by short term gains (an exception is the pharmaceutical industry where the necessary testing and approval regiment is already a long term investment).

>>8062431
yeah but even pharma doesn't support academic research because the reality is academic research doesn't have the same stringent reproducibility requirements as industry
if you're doing science for a company your results need to happen every single time
if you're doing science for academia it only needs to kind of work once, and you can crank out a paper and be done with it

We are not ready yet.

Their science and their understanding of reality are too advanced.

because we are the ayy lmaos

its the only logical conclusion...

+ayy lmaos should have visited us by now
+we have advanced technology both a long time ago and present day
+they believe we arrived here as bacterias on a meteor

just think about it. all this time we've been searching for ourselves

same reason I dont visit africain tribes

>"i" is defined as the square root of -1!
That's not how it is defined in highschool

The issue is that even accomplished logicians will defend a Platonist position (in fact, instead of ever defining a Platonist position, they declare the opposite as absurd and speak negatively of those who hold it).

But looking back at math reforms (pic related), you can't teach the general kid interesting conceptions, appearently. Probably, there will always be just plug and chuck and crying about it

Formalism was completely btfo by the time of Gödel and Tarski you goober. Most mathematicians and logicians subscribe to some version of structuralism nowadays. Some are reservedly platonist, I'll give you that, but even they are not even close to 'muh forms'

enroll in an online degree asap

programming languages are a means to an end. what you should really learn is math.

>like steve jobs.
First of all, kill yourself for wanting to be "like steve jobs".

That aside, computer science isn't only about coding, unless you're at some mediocre uni in the US, trained to be a code monkey programmer, in which case your coding ability might as well be the only criterion for being good at "computer science". Actual research in computer science will require apt mathematical skills as well, not just coding ability. Finally, designing computers and devices falls under computer ENGINEERING, not computer science.

This is my function file:

--------------------------------------------------------

function dydt = ode5( t,y,R,L,C)

dydt = zeros(2,1);

dydt(1) = ((230*sqrt(2)*cos(100*pi*t))/L)-(R*y(1)/L)-(y(2)/(C*L));
dydt(2) = y(1);


end

--------------------------------------------------------

This is my script:

--------------------------------------------------------

R = ...;
L = ...;
C = ...;

tspan = linspace(0,1,10000);

y0(1) = 0;
y0(2) = 0;

[t,y] = ode45(@(t,y) dv5(t,y,R,L,C),tspan,y0);

plot(t,y(:,1),t,y(:,2))
legend('i','q')

--------------------------------------------------------

Now my question is... Where the hell did I go wrong?

Because the "i" function doesn't like like the derivative of "q" in the slightest.

>>8061854
>Where the hell did I go wrong?
wrote shitty code.
magic numbers
called your function ode5 for some reason
not enough matrices

>>8061867
How do I improve? Please I want to learn.

>>8061752
Sorry, meant:
Does v'(y) = y*u(y)?

>>8061752
What is v? What u? What is x?

Does v' mean the derivative?

>>8061759
Yes.

https://en.wikipedia.org/wiki/Notation_for_differentiation#Lagrange.27s_notation

v and u are both functions

Did you just watch inception? It doesn't work like that in real life.

i think it does

>why is it even possible for a mechanism's operation to change its structure

Rather than answer your question I rephrased it in order to point out how stupid you are.

Psychology lacks objective constants and baselines for scientific study because the human mind and the way it reacts to things does not have agreed upon definitions or guidelines.

>>8061620
Mathematician here. I personally think that psychology is an important up and coming experimental science. It doesn't have the foundings that the other sciences have, but it's improving all the time, theories being replaced by newer ones, and once it does have a proper founding, I believe that it can really go far.

>>8061620
It uses the scientific method therefore it is a science.

The problem is that many non scientific ideas long ago crept in to psychology and they have a hard time getting rid of those ideas.

However there are plenty of examples of good science in psychology. Get over it.

>>8061590
No.

He's absolutely right.

Why don't you go to your local natural history museum and have your brother talk to a curator?

is it just (non-avian) Dinosaurs or does he believe all paleofauna (maybe even flora?) is fake?
