DOCTOR X ANSWERS #4

Abv asks:
Are you just the creator of this site 'cos that is really, really lame. So lame.

DOCTOR X replies:
If this page, in any way, offends you, I'd suggest you contact the site owner and get him to take this page down; I am not the creator of this site. Perhaps, as opposed to whining like a little Tiffin Girl, you could stop using this site.




Tjfidf asks:
What is a boson?

DOCTOR X replies:
Short answer: A boson is a class of particle (the other being fermions). More often than not, they carry forces and fields. An example of a boson is a photon.

Mildly Long answer free of maths: Its possible to solve Schrodinger's equation for the hydrogen atom to calculate its energy levels and spectrum. This worked pretty well until scientists realized that some of the lines in the spectrum were actually just closely-spaced pairs of lines. This wasn't supposed to happen so they postulated electrons had spin angular momentum (google it).

Fermions have spin angular momentum 0.5ħ, 1.5ħ... whereas bosons have a spin angular momentum of 0, ħ, 2ħ... For reasons unknown, fermion wave functions are always asymmetric while boson wave functions aren't. In a system of identical particles, a switch between two particles can't cause any physical changes in the system (and therefore the wave function can only be change by +/- 1).


This means that two fermions cannot share the same quantum numbers and state whereas bosons can. Therefore, bosons often act as force carriers.



marvin asks:
what is the difference between time and space


DOCTOR X replies:
Space is a set of dimensions; time measures the changes in these dimensions.




SPECIAL ANNOUNCEMENT:

THE DOCTOR X AWARD FOR MOST WORRYING/POINTLESS/OFFENSIVE QUESTION GOES TO ABV WITH HIS QUESTION: "Are you just the creator of this site 'cos that is really, really lame. So lame."

THE JUDGES SAID:
"His use of repetition is really, really lame"
"This guy really has no life"
"Utterly pointless"

 STAY TUNED FOR THE NEXT DOCTOR X AWARD.
