Does True Randomness Actually Exist?

A classic experiment illustrates why the notion of the wave function as a mere expression of uncertainty about position is incomplete. The two slit experiment.

Oh yeah... I tend to slip into thinking it's about uncertainty... but yeah, what's actually going on is the crazy stuff that makes no sense tongue.png

you can have two people pick random numbers not knowing what the other picked

you take the remainder after dividing by the largest number to pick by and you get the random number

I'm into quantum entanglement!  Its fatalistic and metaphysical tongue.png

What is more fantastical and metaphysical than Heliocentrism and the theories derived from it? 

RoobieRoo

please bro, lets be reasonable, heliocentricism makes sense.

noodles2112

How so? Have you ever seen it proved via the scientific method? 

Most people I come in contact with don't know what it is. They just point to their toy globe or a NASA cartoon pic of the ball in space. 

They don't know the myriad of fantastical speeds it is alleged to be traveling in several directions simultaneously etc. etc. etc.

Please spare me, its observable.

RoobieRoo - since when have you observed stars light years away or a rotating moon or a sun 400 times larger than the moon or water sticking to a spinning ball etc.?

Optimissed - Perhapswink.png

Elroch

noodles, you have observed all of those things on many occasions.

Like most organisms that have done so, that does not imply you know what you have seen.

[An interesting fact is that the centripetal force associated with a basketball rotating at one rotation every 20 seconds is the same as that associated with the Earth rotating once every 24 hours. Do you think a basketball rotating at this speed would cause a problem to something on its surface? Likewise, the centripetal force associated with the rotation of the Earth has scarcely any effect on anything].

Elroch

Centripetal acceleration = V^2 / R

Like I said before, would water stick to the spinning basketball or any other spherical object? 

I have not observed that. 

We are supposedly spinning faster than the speed of sound and zipping around the sun 30 times faster than a bullet from a gun. I apologize if I come across as cynical but that is hard to believe and that is just the tip of the heliocentric iceberg! 

You guys can run circles around me with all kinds of mathematical/theoretical formulas but what does that prove? 

Elroch - I know you could prove(theoretically) that the sun is 1000 times larger than the moon and 1 billion miles away from earth with the expertise you have!

Please try to accurately imagine a basketball you have sprayed with a mister taking 10-20 full seconds to rotate.  Would water fly off?  Not at all.

The fact that our galaxy rotates at 468,000 miles per hour must really blow your mind, given that we are out on an arm and all.

P.S. The speed of sound varies, if you were not aware, and the speed of rotation also varies depending your latitude.  You, personally, are never traveling faster than the speed of sound relative to your surroundings here at the bottom of our gravity well...

The answer is that water does not "stick" to the Earth. It is held between the atmosphere and the ground by the gravitational force pointing towards the centre of the Earth. It provides hundreds of times the centripetal force that is needed to prevent the water flying off because of the rotation of the Earth (without gravity, the water would indeed gently detach from the surface and fly off at a tangent). 

The radius of the Earth is 6378000 meters at the equator (slightly more than at the poles). The speed at the equator is thus 2 * pi * 6371000  / (24 * 3600) = 463 meters per second.

Thus V^2 / R =  0.0337 meters / second^2

Compare this with gravity, which is 9.81 meters per second^2.

i.e. gravity is 9.81 /  0.0337 = 291 times stronger than necessary to keep the oceans on its surface at the equator.

Since a basketball has a radius of 0.12 meters

V^2 / 0.12  = 0.0337 would give the same centripetal force.

Thus V = 0.0636 meters per second.

Since the circumference is 2 * pi * 0.12, this means it rotates:

0.0636 / (2 * pi * 0.12)  times per second

= 1/12 times per second.

Apologies, I claimed it was 1/20 times per second (I did a quick calculation using an incorrectly remembered value for the centripetal acceleration at the equator).

I have not observed that. 

We are supposedly spinning faster than the speed of sound and zipping around the sun 30 times faster than a bullet from a gun. I apologize if I come across as cynical but that is hard to believe and that is just the tip of the heliocentric iceberg! 

See above. It's a very gentle rotation.

You guys can run circles around me with all kinds of mathematical/theoretical formulas but what does that prove?

It is evidence of competence when the results check against reality, as they do.

Elroch - I know you could prove(theoretically) that the sun is 1000 times larger than the moon and 1 billion miles away from earth with the expertise you have! 

No, science can only "prove" true things. It has no choices as to what to "prove".

btickler - "Please try to accurately imagine a basketball you have sprayed with a mister taking 10-20 full seconds to rotate.  Would water fly off?  Not at all."

Is this an experiment that has been done before and I am unaware? 

noodles2112

Elroch - so what about gravity? It is indeed "fickle".

Holds trillions of gallons of water to the ball earth yet allows numerous things to escape its grasp balloons, smoke, lint etc. 

Is not gravity everywhere? If so, why can't they duplicate the ball earth with water holding to it in a laboratory?

You don't even need an experiment.  Let's be real here.

Here's a scale image to show how thin your trillions of gallons of water are...

Deepest point of the ocean = ~10,000 meters

Depth from surface to core = ~3,485,000 meters

Dew on a basketball is a very fair analogy.

So how do you know this is what the earth is all the way to the core when the deepest hole ever dug is only around 8 miles?

Why do you post here?  How do you know any of us exist?  How do you know anything beyond your trailerpark is real?  Same premise.

Sorry btickler.  Just the factswink.png
