I'm building a coil gun but I can't get a high enough current. I'm launching the projectile by momentarily connecting the wires connected to my power supply to the ends of the coil.My PSU supplies 30V up to 5A. But it isn't powerful enough for my purposes. How can I increase the current that goes through the coil?
>>14492540because that's not even close to how magnetism worksThe circulation of a magnetic field around some loop in space is proportional to the current within. current (moving charge) makes magnetic fields. is there any current involved in your hypothetical, anon?
>>14492544>I'm thinking about mass drivers>"Why don't batteries become magnets and lose all of their energy over time just the same as having a load applied?"holy fuck lmao

Could parallel universes with different versions of ourselves exist?
>>14492480They would if by universe you mean all of reality, universe could be reserved for what we can observe/places where particles and shit like this have the values that we measure they have. Where they have other values, those places would qualify as other universes in this scheme I'm currently making up.
I would so suck myself off if I could visit me in a parallel Universe. No homo.
>>14493224It is certain that going to another universe will have you blowing your cock, but if you stayed in this universe and you from a different multiverse came he would be sucking your cock. Obviously the multiverse is a branching decision matrix so your odds of choosing to go suck yourself off directly correlates with you coming to blow you in this one. If you refuse, then nobody will leave nor suck your cock, but if you choose to go every time, then you will never suck cock nor get your cock sucked, but everyone will change places like the infinity hotel. What is the blowjob theory optimal strategy knowing that you want to maximize chances of getting your cocked suck and minimize chances of sucking cock yourself.
>>14492356> far away in spacethere's no space between seperate universes
>>14492292You could have infinite universes with infinite possibilities and still be totally unique.This notion that it means there are infinite versions of you is wrong

Why does perception of time speed up as you get older?
>>14488640Copper deficiency. Tested experimentally, no idea about the mechanism.
>>14488640side effect of decreasing neuroplasticity. After age 28-32, it becomes significantly harder to form new memories
>>14488640For me, it's because I got progressively better at automating my mind and muscle movements.When I was younger I did everything with a lot more thinking / deliberation and stress which makes life go by much more slowly since you're doing something with each moment.
>>14488640time is a feeling of unfulfilled promises, psychosomatic blocks.
>>14489574>the misconception that we've forgotten vast swaths of our childhood experiencesBut this actually happens
Dont you give me the oil drop facfiction, i mean the real mechanism. It cant be that in 2022 we only measure the electron charge with an oil mist. And dont give me some circular technique where you use quantities derived by using the electron charge.
literal children can carry out this experimenthttps://www2.southeastern.edu/Academics/Faculty/rallain/plab193/page1/page38/page38.html
"charge" is relative therefore you need to establish a difference in energy level firstwith this considered, "positive" and "negative" has no objective value
>>14492887>"charge" is relativecharge is certainly not relative. what the fuck? is mass relative too? you are retarded.
Here's another way to do it.https://www.researchgate.net/publication/239643179_Shot-noise_measurements_of_the_electron_charge_An_undergraduate_experiment
Measuring the fine structure constant is essentially measuring the charge of the electron in certain natural units, so here's a paper measuring that.https://www.nature.com/articles/s41586-%3020-2964-7

Currently writing a thesis, and I wanted to ask for some opinions on this subject since you guys seem to have great ideas.>What are some causes of sickness absence in the workplace?>How can the leaders affect sickness absence among their employees?>What can be done to prevent or reduce sickness absence?Thanks in advance bros
>>14491955Calling a thesis for homework is a bit silly.
>>14491932Thank you for the extended answer, anon.I will keep this saved.I realize a lot of it is also personality based, and much more complex depending on differences in jobs. Some jobs have more autonomy than others, and generally speaking less autonomy and high workload means higher sickness absences.
>>14491864If it's not due to actual sickness, leadership or the work environment is probably shit. If morale is bad, you're SOL. Leadership can lead by example, but this is mostly going to start in the hiring process to find employees that are less likely to call out. They can't do anything about people actually becoming ill outside of making sure that employees are healthy.
>>14491955It's a bit more scientific than homework and idk what other board to post it on.>>14491973Sounds like a socially good work environment. What kinda job do you have?>>14492009I agree with that, I have done it too when I needed to do uni work but my job isn't possible to do from home.Here where I live its pretty common to be able to work from home, let's say if you work at a university or something like that.
>>14493243What does SOL mean?But yes I agree it starts in the hiring process, by hiring reliable people who are motivated to work.The nurse profession has been plagued with high percentage of sickness absence due to stressful work environment, low wages and sometimes unfavorable work hours.
What does that mean the higgs field gives particles their mass? I have studied QED and electrons just have mass. Like we measure the mass and charge and just put it in, we dont know where any of the values come from.Doing some brief reading it appears the higgs field is related to problems with the weak force. Calculations didnt make sense so they were fixed by ADDING a new patch just like so many other things are discovered in physics (Neptune, infrared light, dark matter). This patch is the higgs field. Is this right?
>>14493201That's not the paper in my post. I'm not sure what you are trying to accomplish with this
>>14493215The quoted part>If the intermediate vector bosons are observed to have masses above 100 GeV this possibility must be taken seriously.Is the very last sentence of the paper you so generously linked here>>14493173The pic about SU(12) comes from your first source>>14492900>https://doi.org/10.1016/0550-3213(81)90580-0From section 4/>4.

>>14492439yep, this thread is a bunch of dumb moneys looking for their dopamine hookup. 100% reddit
>>14492419Martha no...
>>14493218>If the intermediate vector bosons are observed to have masses above 100 GeV this possibility must be taken seriously.That paper was from 1981, before 100 GeV was reached. Since then the model has been ruled out by experiment and I said as much in my post. The point is that it is a confining theory that is smoothly connected to the actual weak coupling Higgsed standard model. It is so smoothly connected that people in 1981 could not actually tell the difference between the two. Do you see my point now?>From section 4/>4. Four-Fermi interactionsOk I missed that, but the SU(12) is referring to a global symmetry in the SU(2)xU(1) gauge theory. It is not some kind of GUT with an SU(12) gauge group.

Previously >>14461881.Talk math.
so um, I've got a bit of a tard question here.I got my math degree at a 5th rate university and I somehow landed a gig at Cornell, and they said they would pay like, one class a semester. I'm pretty sure that I am completely unqualified to take any mainline graduate math class there. Should I just yolo it and see where I land or is there a way to skill check myself before throwing myself into incinerator and wasting everyone's time?
>>14492779Nevermind I managed to finally solve this.
>>14492779>>14492945I took [math]p=10[/math] and ended up with:[eqn]\int_{0}^{1} x^{\frac{-9}{10}} cos(x)dx = \int_{0}^{1}y^{-9} (10) y^{10-1}cos(y^{10})dy[/eqn][eqn]=10\cdot\int_{0}^{1}y^{-9} y^{9}cos(y^{10})dy[/eqn][eqn]=10\cdot\int_{0}^{1}cos(y^{10})dy[/eqn][eqn]\approx 9.7718427[/eqn]Which is also the value I get via the online integral calculator.

I never understood why my physics professors kept trying to define vectors as something that transformed in a specific way until I learned about tensors.Turns out they just meant tensors. It was all tensors.
