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.

The life of a labourer with Physics

As some of you might know, I currently work as a construction labourer, saving up to be able to afford the Bachelor of Science (Physics) courses. The work is very taxing on the body, but the mind is not affected much.

While working, I occasionally think of the physics principles involved in whatever I'm doing right now, say I'm demolishing a wall. Naturally, Newton's Third Law of Motion floats around in the back of my head whenever I'm using the rotary hammer (a type of jackhammer), and how it makes my arms sore. Much of the reaction force is mitigated by the weight of the hammer itself, but the concept backfires when you have to pound locations  higher than you.

I was having a rough time shoveling sand, thinking about the shovel being a Class 3 lever, when I realise I've also been unconsciously working the shovel using the couple mechanic. I had my left hand pull the shovel up, while my right hand pushes down on the handle.

A poorly-drawn shovel
A couple is a system of forces with a resultant torque but no resultant force (obligatory physics definition)

Green Arrow : Force that left hand applied
Pink Arrow: Force applied by the right hand
Black Dot: Centre of rotation.

Get the picture? (no pun intended)

These thoughts made me realise how much I enjoy physics, and how good it would be to have a physics degree.

P.S. What is it with Physics students/teachers and their lousy drawings?

A Night with the Stars

Here's some really interesting knowledge to relax your mind after the constant wave of X-ray postings:

If you didn't know Pr. Brian Cox before this, you do know. Professor Brian Cox is a British physicis- I think I should leave that to wikipedia. Read his wikipedia entry to know the nitty-gritty stuff!

In general, he's a pretty awesome person. A rockstar physicist.


I implore you to watch this video, not only for the sake of knowledge, but the video is very entertaining and explains the basics of quantum physics (Quantum Theory) in great detail. Recorded meticulously by the wonderful people over at the BBC at the Royal Institution of Great Britain, Pr. Cox brings us mundane people to the wonderful world of particle physics, in just one hour. You'll be wishing that the video lasts forever by the time you're done.

Pr. Brian Cox - A Night with the Stars.

Did you think physics was nerdy? Well, you thought wrong.
