Hi...(adsbygoogle = window.adsbygoogle || []).push({});

I have a little question I've been wondering.

In my physics book (Young & Freedman - University Physics) the "Uncertainty Principle" is given as:

[tex]\[\Delta x\Delta {{p}_{x}}\ge \hbar \][/tex]

But on Wikipedia, and my math-instructor tells me the same, it's given by:

[tex]\[\Delta x\Delta {{p}_{x}}\ge \frac{\hbar }{2}\][/tex]

The difference being the division by 2.

So, what is the correct one ? And does it even mean anything at all ?

Because, by dividing by 2, aren't you able to determine one of the things even more precisely, or...?

Well, I'm a bit confused, so I hope anyone can tell me the truth :)

Regards
