Higgs Boson Blues

They gave Nobel Prize long ago but I some how did not give it too much thought until this week.
But now it hounds me...
1) on Monday I had Higgs mechanism during tutorial from Astrophysics... 
2) then I have found a lecture that took place at my university some time ago, that one could refer to as a lecture about 'Brout-Englert-Higgs Mechanism for kids'.

3) And now I have some how come about the song "Higgs Boson Blues" on youtube while watching make-up tutorials... I do not even know (?!)... anyway
Here is Nick Cave and The Bad Seeds playing Higgs Boson Blues:


I mean song has nothing to do with physics but it made me think about all that Higgs stuff.

It is just Tuesday... but I am gonna claim that this is 
Higgs week of my life!

...now I better go back to working on my thesis...

H-bar curse

When you start studying physics you get introduced very quickly to h-bar constant.
H-bar is called the reduced Planck constant (Planck constant divided by 2PI) or the Dirac constant.
H-bar is fantastic!
Why? Because it is always with us whenever we work with quantized light or matter.
And who doesn't like that?
If you studied physics long enough you are slowly adjusting to not forget a bar on your h. interestingly enough after few more years in a field it becomes a challenge to not write h-bar in equations wherever h occurs.
I thought it is just me but not it is a curse and most of the students fall in that trap.
There is nothing we can do about it...
We can live proudly with our curse...

There is actually one more stage it is called "natural units stage".
(In natural units h-bar=1)
Once you get there you will never write h-bar again.
I am not there yet but I am getting there...
