Quantum Physics

I stumbled upon a video of an explanation of matter and whether it is waves or particles. What is strange is I was just talking about this with a friend a few months back. Then I saw this video which explained if very well. I thought I would share it with you.




Let me know what you think...

Randy,

I like it so much I'll probably use it on my blog.

It is just the dual nature of photos that seems so incredible, but the implications which this has for understanding nature.

It's a starting point for understanding quantum physics - including the nature of consciousness itself.

Randy,

I meant to write "It isn't just the dual nature of photons".

But was distracted.

Randy,

The video needs to be a bit more detailed in the wave crest, versus wave trough - additive vs subtractive interference patterns.

I'm afraid that some viewers might be scratching their heads on that.

An oblique view of waves would work better don't you think?

Two crest makes a high point.

Two troughs makes a low point.

A Crest, and a trough makes a mid range point.

When we're speaking of EMF, or photonic energy then we'd be seeing the interference pattern.

Which we know should not happen with just one photon - unless of course the one particle (photon) is a wave.

But how can it be a wave when shooting one photon through one slit shows the pattern which a particle would make?

Hey, there's something going on!

How can the basic property of existence exist in a dual state?

Way cool.

What blows me away is the fact that by observing the photon it changed its behaviour.
From Wiki...

In science, the observer effect refers to changes that the act of observing has on the phenomenon being observed. For example: observing an electron will change its path because the observing light or radiation contains enough energy to disturb it.

In quantum mechanics, if the outcome of an event has not been observed, it exists in a state of superposition, which is being in all possible states at once. The most famous example is the thought experiment Schrödinger's cat, in which the cat is neither alive nor dead until observed — until that time, the cat is both alive and dead (technically half-alive and half-dead in probability terms).

In physics, a more mundane observer effect can be the result of instruments that by necessity alter the state of what they measure in some manner. For instance, in electronics, ammeters and voltmeters usually need to be connected to the circuit, and so by their very presence affect the current or the voltage they are measuring. Likewise, a standard mercury-in-glass thermometer must absorb some thermal energy to record a temperature, and therefore changes the temperature of the body which it is measuring.

The Heisenberg uncertainty principle is frequently, but incorrectly, confused with the "observer effect", as it relates precision in measurements related to changes in velocity and position of certain particles relative to the perspective the observer takes on them.

I don't get it :)

Me neither, Wife of Randy! haha It makes my head hurt just trying.

By the way ... come back, Randy ... we miss your photos! :)
