can magnetic fields cancel and if so how so? like magnetic fields are vectors and just cancel whats actually happening when magnetic fields intersect?

Please don't be condescending.

Yes, what I am having trouble understanding is WTF is north of east, and east of north. And why is the resulting answer north of east. Is it because thats where the direction would be heading if say both vectors were physically acting on each other because vector A has a larger magnitude? There are many questions I have.

I don't get it, can you at least tell my the WHY's and HOW's on how to solve this?

Whoops I did not see this thread before I posted.

Hello, my physics professor glosses over a lot of problems. She teaches theorem completely, but never shows examples, leaving me to use my small IQ to figure things out.

Help? :D

Hello. I have trouble solving the given problem, if someone would be so kind to help me, I would appreciate the effort.

Find the normal differential equation for the function y(x), so that the integral I=∫f(x,y,dy/dx)dx has an extrema, f(x,y,dy/dx)= αx^2 [y^2+(dy/dx)^2]+βy^2.

A blackhole size of a rice grain will have mass of the moon.

If a blackhole was indeed created by colliding a few particles, it would take millions of years before it was even noticeable.

>Abiogenesis
I dont know what you are going for, but I was trying to explain to kids about the big bang theory having a starting point at t=0.

I have no intention of starting to debate of abiogenesis and what not, since it is not relevant.

because it continues with:

"The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. "

so there was no point

nice way of reading the whole thing.

Maybe you should get some reading comprehension you dota2 rager.

tl;dr version:

"The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. "

I recommend reading this before further embarrassing yourself:

I guess you have not even studied a cosmology course for elementary school students.

With the bigbang theory that's exactly whats assumed.

If you assume there was time before big bang, then the theory doesnt work and you should ditch big bang and invent something more clever

sorry but u didnt even draw the 3 axis correclty in the picture so cba read your paper :(

though getting only a B.S. in physics would be stupid.

A lot of engineering has physics and math peoples (which are included in science)

Drugs are a pretty huge field too for biochemists

its not a sensible question to ask what happened or existed before time

No Ive actually slept as long before.
But I think my sleep quality is better, and I dont feel tired in the morning.
