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?

because that's not even close to how magnetism works
The 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?

Could parallel universes with different versions of ourselves exist?

They 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.

>>14493224
It 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.

Calling a thesis for homework is a bit silly.
>>
>>14491932
Thank 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.
>>
>>14491864
If 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.

Sounds like a socially good work environment. What kinda job do you have?

>>14492009
I 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.
>>
>>14493243
What 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?

>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 interactions
Ok 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.

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?

I 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.
