Why is 1/2 so important in the QM world???

 

For instance SI units " mostly uses" bases of 10 below is an image that shows this.

 

A good example is .5c = 149.896229, are the meters 1/2??

Then their is the case about the exponent , how does this also relate to 1/2.

Energy of photon :

c*h =299.792458*6.626e-34 = 1.9864e-31

c*h =299.792458*6.626e-34 = 1.9864e+31 ???

 

Could this be 1/2 as well??? AS IN THE BASES OF 10, SUCH LIKE 10/2 = 5?

 

I have seen the n^(n+1) deal but how would this yield 1/2 in the exponential properties of 1/2 making this =1?

This is why I assumed this for the energy of the photon:

1.9864e-31= 1

1.9864e+31= -1

 

I know that may be wrong!

 

I am quite familiar with units and conversions, but this area of 1/2 and what it means is wayyyyyy confusion as per the protocols of physics and strict guidelines of SI units coupled with conversion factors.

It has no inherent meaning.

It has no inherent meaning.

So what you are saying is that 6.626* 10^-34 where the base system 10 is used has no inherit meaning??

 

 

Euler is another one that uses ten base log scales here is the link:

 

http://en.wikipedia.org/wiki/E_(mathematical_constant)

 

Why do they rely on log base ten scales for accounting if there is no inherent meaning to them?

 

Or does accounting not need apply to " real " science and real physical elements?

Nope. It is completely dependent on our choice of unit system, which is arbitrary. Dividing a day into 86400 seconds is arbitrary. Dividing the length of the meter based on the distance from the equator to the north pole is arbitrary. Our current units for the second and the meter are based on those original choices. Our choice of mass originally was based on a cubic cm of water being 1 gram. And those are the reasons that Planck's constant is 6.626* 10^-34 Js, and why c is 3*10^8 m/s, etc. and not some other value.

Thanks, no one ever says this here, this has really helped answer my questions as to why equations need to balance, it seems that nature always will have the last word..
