   Hi,
   I was looking at the wikipedia article for spin 1/2 http://en.wikipedia.org/wiki/Spin-½ and it stated that √(½(½+1))ħ=√3/2ħ. According to my math it is √¾ħ. Is this just a typo or am I missing something?

   Be careful, what you wrote is ## \sqrt{\frac 3 4 }\hbar ## and what the wiki page wrote is ## \frac{\sqrt 3}{2} \hbar ##. They're the same!

   Ah I see. I went off initial simplification, not realizing that they are the same.
