I need to choose an organic chemistry (200 level) project to run for my ten week organic 3 class in the spring. Can /sci point me towards anything interesting pertaining to aromatic rings, conjugated systems, the Evelyn effect, or diels alder reactions (those were my favorite subject matter)?

What exactly are electrons? I was working through a chemistry chapter today and learning about orbitals(spdf things). Feels like it's never properly explained in the text

If you are asked to demonstrate an equation or principle, is it asking you to derive it or stick some arbitrary numbers in and get an answer?

Sup /sci/. How do B cells manage to produce different antibodies? Do they somehow mutate their DNA to accommodate for varying antibodies? Or maybe they splice their mRNA differently? I'm confused.

Temperature calibrations

Temperature calibrations 2 posts and 0 image replies omitted. Click to view.
Hows it going /sci/ got a random question. At my work I got moved to a calibration department (we calibrate subsea equipment for ROVs etc). so in this department there is 3 tanks: 2, 15, 35 degrees. When they calibrate temperatures they put the instruments through the tanks in this order : 15, 2, 35. would any other order make the calibrations go quicker. there is a temperature probe that shows us when the temperature is settled. the order right now takes a while. would doing it 2, 15, 35 be quicker settling time wise. Sorry for the really shit question. I was just curious

sup? i am searching for a book i had read at least 10 years ago but i dont know how old it is. i cant remember anything but i feel like this book really stigmatized my thinking. Anyway here is what i remember: The book was written by 2 people. I am not sure if it was by 3 people. But i remember 3 names. I think one of those two people have got a nobel prize in chemistry or physics. But i am not 100% sure. For some reason i feel like one of those or both are French. But this again isnt sure. It has to do something with france cause: The book generally is pro nuclear and is debunking many myths about "how bad is nuclear energy" . So it speaks greatly about france i think. The book also speaks about many pseudoscience things and is debunking them. Most notably i remember that it debunks water finding with sticks. But also much other fake science. for some reason i feel that the cover of the book is orange.

sub /sci/. i have a task i need help with. i need to come up with good design idea of spaghetti bridge that could hold up to 1,5 kg and use as less spaghetti as possible. post ideas if you have any. creativity, weight, strength adds extra points. length 1,5m, thread, glue, spaghetti can only be used

Why do people pursue hard science like Physics and Engineering when there are no jobs? Do they think they will be the lucky ones to make it? That they will end up at Google X or something?

hay /sci/ i'm visiting from /tg/ just wanted ask after reading ITT: We fix this chart I've always had a passion for basically all of god tier how should i go about getting them with in a reasonable amount of time relatively speaking? p.s. I am aware that things like medical may have to be dropped becomes of time constraints. p.p.s. Not share what field of engineering to go in to any suggestions? p.p.p.s. I'm really fucking tired right now so i'm sorry if this doesn't make any senses.

How could we test the hypothesis that between every Planck length of time in our universe, there occurs an incredibly vast amount of time in an infinite universe that is simulating our own through simple program automata? If our universe is fundamentally discretized, how can we say for sure what happens in the space in-between?

Lorentzian Relativity

Lorentzian Relativity 10 posts and 7 image replies omitted. Click to view.
Someone deleted the thread I was going to post this in, presumably for "anti-semitism" (i.e. pointing out that Einstein took the credit for tons of stuff that wasn't his work). The ideas of Lorentzian relativity are: 1. That you can explain length contraction as an actual physical deformation of objects, by considering light moving at c with respect to one 'objective' frame, and deriving that transforming spherical field/orbit solutions of Maxwell's Equations ("objects") into some Gallilean frame with 'actual' velocity v causes a deformation in the direction of movement. 2. That you can explain time dilation as an actual physical 'slowing down' of oscillatory processes, by considering the time taken to move through orbits in a deformed field. If you read the relevant papers by Lorentz and Poincare you can see how this results in an illusory "local time" which anyone moving at some velocity will consider to be 'real'; and how the details of measuring distances/times (via synchronisation of light travelling at c w.r.t. the objective frame), and mutual contractions of apparatus, will result in light always being "measured" to move at c in any frame (tl;dr you never actually measure the 1-way velocity of light, you always measure the 2-way velocity; and though you 'actually' experience light moving at either c+v or c-v in your frame, the overall 'time taken' always suggests that the light is simply 'moving at c').
