Substituting electrons with photons

It has been quite a while since the last post. Here's something directly from the labs of the University of Pennsylvania:

First Physical 'Metatronic' Circuit Created

 The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.

This discovery, or rather, technology has huge implications. Light travels a million times faster than electricity (exaggeration. don't quote the math), but that's not the major thing here. Electronic circuits are limited by orientation of poles, and the nature of electrons themselves. If light is used to replace them, infinite numbers of circuits can be created. There will be myriad options, more complex circuits can be created to perform tasks that would otherwise be impossible with the current electronic circuits.

The field of Electrical and Electronics Engineering has just undergone a paradigm shift- There are so much more to discover.

MAKE A LASER -FINALES FUNKELN-

harvest a bunch of LEDs from DVD drives

buy a collimating prism 

make a superpowerful superlaser

profit?

I'm really tempted to try making a superlaser myself. I have the knowledge to do so. Unfortunately I don't have a bunch of DVD drives lying around my place.

Nor do I know where do I purchase a collimating prism. I could make one myself, but I can't seem to get the glassy texture right.

MAKE A LASER!

My take on quantum healing

So I've been receiving messages asking my opinions of quantum healing. Quantum healing is a belief that are based on a scientific level that there are things that happen on the microscopic scale that we can't fully explain.

The world inside an atom is a strange place where things don't behave like they do in the macroscopic world. Particles behave bizzarely, waves behave like particles, particles behave like waves.

Particles in the universe are always in communication with each other. This is a true physics fact and is used as the basics of quantum mysticism, eg: quantum healing, The Secret, and so on...

Some of you might be familiar with the Pauli Exclusion Principle. No electrons can occupy the same energy level. This means that each and every electron in the universe must not share the same energy level. This brings us to an amazing hypothesis: Every action that you do has a resounding effect throughout the universe.

An action will definitely involve the movement/motion of electrons. The electrons shift and jump, changing energy levels. However, as the Pauli Exclusion Principle states, every electron in the universe will respect the changes in the aforementioned electrons by changing theirs, effectively impacting the universe.

Everything is connected to everything else.

If the above is true and proven, then what is the scientific argument that disproves quantum mysticism?

Quantum theory doesn't just apply to subatomic particles, it also applies to you and me. Why don't we see the effects? The reason is due to the smallness of Planck's constant (which was discovered by coincidence).

An example: Say you want to 'teleport' out of a closed room. Before you scoff at the idea, let me remind you that quantum theory can show you that the above scenario is theoretically possible. Feynman's path integral (a physics formula) displays the probability for said teleportation to occur.


The equation for Feynman's path integral (which takes all the probable paths a particle takes through the universe), heavily simplified is represented as follows.

MSPaint to the rescue.

t = time you have to wait to have a reasonable chance to teleport to your destination
x= distance you want to travel
^x = length of the room
m = your mass

h = Planck's Constant.

In this example we let x be 3m, ^x be 2.5m and m be 60kg.

I hope you have a calculator handy because I'm not displaying the calculations here.

...

...And we get... t = 6.9 x 10^35 seconds
(correct me if I'm wrong)

In years, that would be  2.18652476 × 10²⁸ years



Which is... let me put that into perspective. The current age of the universe is 13.7 ± 0.13 billion years. (x10^9)

So yes, there are strange stuff in quantum theory but there's absolutely no chance we'd get to apply them in our day to day lives.

TL;DR = Quantum Healing probably doesn't work due to the fact that quantum effects are only observable on the microscopic scale.
