Any Physics questions?

>> No.1139033

Why do we bother continuing if we know we'll never be able to know it all because we are part of the system? ;_;

>> No.1139039

is god real? back up your answer with proof either way.

Well, just becuase we may never know everything, doesn't mean we can't know some very important things.


Your logic is flawed

In that case, how do you debate people using the time argument when talking about physics? "Before, nobody thought we could surpass the speed of sound... so maybe in 100 years, we can surpass the speed of light!"

The rules don't change, but our models do. How do you deal with these people?

>>1139099

We knew we could surpass the speed of sound. We'd been doing it with cannons, bullets and even whips long before the first planes. What we didn't know was how an aircraft would handle breaking the sound barrier.

I am both curious and willing to learn, but do I need to have superhuman mathematical capabilities? I did great in high school math, but that admittedly doesn't tell much about my reasoning skills. Would I want to develop those further before I try to move on?

>> No.1141304

More math than physics, but:
If I use the vector (non-real) part of a quaternion in place of an imaginary number in Euler's formula, do I get a point on 3-sphere of radius equal to 1 (as I could get a point on a circle with Euler's formula)?
I mean, e^(xi + yj + zk) instead of e^xi.

It we create two anti-hydrogens, and one anti-oxygen can we make anti-water ?

>> No.1141446

here's a cool story
In my first year in college I failed a physics exam, because I didnt know what a gyroscope is. We didnt learn about it in the class but somehow the questioner though that its important enough.

So gyroscopes, why are they important?

>> No.1141482

>>1141446
They are usually used in basic physics classes to demonstrate the conservation of angular momentum and shit, Like a biycle. The are very usefull in moving things in space, or observation the motion of somthing.

Fuckin' Entanglement, how does it work?

If I collapse the waveform of 1 electron, will it's entangled twin "respond" by having it's waveform collapsed?

If so, why don't we have FTL communication yet?

Wouldn't a blackhole push space into a pocket creating another bigbang whos properties are relative to the amount of energy poured into it?!

Why light is considered to be time

>> No.1144011

>>1144001
I can answer that one.

Because speed of light is the max speed information can travel. So basically, every point in the universe is sending "updates" of their existence to other points in the universe at the speed of light.

Now you can imagine what funky consequences that has and how things are all relative.

how does the electric field of a single electron look like during the double slit experiment, before the electron reaches the detector?

so time can get curved just like light when passing an object with big mass?

speed of light is not the fastest speed. God can ran faster
