To see this strange optical phenomenon yourself, all you should need is a small mirror and a bathroom shower. There is also a light in the ceiling of the shower, which is probably an LED, but I think this should work in any shower. The effect is especially noticeable for me, because I have...

Is There A Universal Now?]]>

Disregarding, at least for the moment, the question of whether time, space and energy are quantized, let’s imagine two quantum particles in a perfect vacuum.

Particle B is at rest. Particle A is launched at particle B at speed s. Assuming a direct, head-on collision between two inelastic particles and conservation of energy, we get a classic Newton’s cradle…

Particle B will be ejected at speed s. Particle A will be at rest in...

Conservation of kinetic energy between neutral fundamental particles in a vacuum?]]>

I think that a falling human body reaches a maximum speed of about 125 MPH (200 km per hr).

How fast does a bullet fall? I have read about people being killed by bullets fired into the air and hitting a person when they fall.

Would a spherical steel ball bearing fall faster or slower...

Maximum speed of falling objects?]]>

The MM experiment is wrong!]]>

given:

a circle, radius = r;

angle of one radian.

Radian

https://en.wikipedia.org/wiki/Radian

A radian on a circle has sides: a radius, a radius, an arc with length 1 radius.

- - -

(1) Area of the circle = π.r^2

A circle has 2.π. rad.

If

area of 1 radian angle =1

then

(2) area of the circle = 2.π.

(1), (2) => 2.π.

The area of two radians makes (the area of) one square?]]>

A quantum state has to have a global phase, but this can never be measured, so it isn't information (?!)

So what's left? The global phase is included (it has to be) in measurement operator notation; measurement in QM is the same operation as converting the momentum into a single bit of . . . information.

So, unpick the standard double-slit experiment in terms of a set of measurements of individual particle states; the...

Time and information]]>

I was wondering is someone here could verify the square's side length using Trig. Two decimal places should be sufficient for a "close enough" representation of a squared circle, right?

An Inconsistency Between the Gravitational Time Dilation Equation and the Twin Paradox]]>

I have some question about "the gravitationnal force" because this concept seems (for me) not physicaly accurate.

At first approximation, everybody knows that the intensity of the gravitationnal force is proportionnal to the inverse of the square of the distance.

F(d)=GmM/(d*d)

Therefore at some distance everything that is at distance d will be attracted with the force F(d)

So far so good.

But this force F(d) act into the whole tridimensional volume where there is gravtitationnal...

Something strange with Gravity ?]]>

I was wondering how we know the gravity field expand from its source.

Theoricaly as soon as "a mass" (it could be "pure energy "but let us do simple work) appear ,

So fare so good...

But how do we know this ?

Ocham rasor ? Obvious thinking ? Observation ?

Hum... <But what say science ?

Nothing as far as i tried to figure out...

How does Gravity propagate ?]]>

Can we make time stand still?]]>

At 14:45 the object is placed on the treadmill.

If the object would advance towards the front of the treadmill (towards controls) would it be moving faster or slower than the treadmill belt?

I claim that in order to move faster than the treadmill belt the craft would have to beat the belt to the rear, falling off the treadmill BEFORE a line on the belt would get there.

What say you?]]>

The results show that increasing the accuracy increases the entropy of the clock's environment.

Which of course speaks directly to information entropy, and the transmission of "accurate" information.]]>
