So since we can see distant stars and the CMB and hence see into the past, that is proof the universe existed before our consciousness, which you means you don't have to exist for the universe to exist, which means objective reality is real.
>>7786432 I remember from the KIC threads that we were possibly one of the earlier civilizations that came into existence that we can see in our observable universe. Otherwise we could have detected the EM signals from their energy usage coming from other planets
Dr. John Brandenburg: Of all the pictures I've seen from the moon that show possible structures, the most impressive is a picture of a miles wide rectilinear structure. This looked unmistakably artificial, and it shouldn't be there. As somebody in the space defence community, I look on any such structure on the moon with great concern because it isn't ours, there's no way we could have built such a thing. It means someone else is up there.
I'm just having fun with this breadboard but for some reason, I can't figure out why the middle LED (b/w e and f) blew out when I used my 9V battery. It lit up and quickly shut down. I smelled fumes so I assumed it blew.
Note that there used to be another LED at the bottom lined up with the others in the row. I used resistors >1k ohms for all the LEDs except the one in the middle that blew. I don't understand much about Ohm's law, but is the fact that I didn't add a resistor to the middle LED the reason it blew? If so, why? I already had other... Comment too long.

>>7786371 >but is the fact that I didn't add a resistor to the middle LED the reason it blew? Yes, you fucking clown. I cannot think of a better example of someone finding a simple example of "This does that, but if I change this one variable, this other thing happens." Do you really need someone to tell you that? The other resistors have no effect on the total current flowing through the LED that blew out.
>>7786371 >I already had other resistors so I thought there would be enough resistance. The other resistors don't really do anything to limit the current through that burnt led, because they are in parallel.
Hey /sci. Greetings from /lit. Have any of you guys ever read pic related? If so, how advanced/thorough/complex was the physics/math/chemistry/other science related shit in the book? As a STEM noob, I found that I could recognize some references, but not much. I guess I mostly wanted to see if more science-y people are as impressed by Pynchon's knowledge of science as regular literary English grads who just read novels.
>>7786303 Yes I've read it. The thing is, while it does certainly touch on several scientific topics, it's usually in service of some poetic metaphor and as such is not as deeply technical as it seems.
>>7786334 >is not as deeply technical as it seems.
I found that having a mathematics background let me appreciate certain puns like Gregory Hilbert-Spaese or shit like that. Not much else. He doesn't have deep scientific insights to offer, he just draws on technical imagery for metaphors and whatnot.
>>7786303 I love this book and have read it many times. but it's literature. no complicated math. if you know Pynchon, the math is in there usually to make a pun. I remember a sex scene where slothrop is kissing katje on her osculating curves or something like that. same with chemistry.
it's a very funny book and just good conspiracy style sci fi. very clever and original fantastical characters with strange skills and it takes lots of turns. occasionally has some inspired metaphysical moments.
If you're a math major. From pre-calc to now, include books if possible. >CS Foundations - c++ bjarne Theory - Automata Ullman OS - tattenbaum Compilers - Dragon book Discrete maths - Rosen Calc - Stewart (it sucked ass)
But unless you’re the kind of rabid physics fan who’s seen her papers on semiclassical Virasoro symmetry of the quantum gravity S-matrix and Low’s subleading soft theorem as a symmetry of QED (both on approaches to understanding the shape of space and gravity and the first two papers she ever authored), you may not have heard of Pasterski. A first-generation Cuban-American born and bred in the suburbs of Chicago, she’s not on Facebook, LinkedIn or Instagram and doesn’t own a smartphone. She does, however, regularly update a no-frills website called PhysicsGirl, which... Comment too long. Click here to view the full text.
