Re: Question about QM using classical and quantum elements

Ah right, thanks. Just wanted to make sure I wasn't missing something glaringly obvious in the article, the only quantum stuff I've really looked at so far are the uncertainty principle, Photo electric effect and Young's single/ double slit experiments so I thought there was some extra layer of comp...

Question about QM using classical and quantum elements

I was reading this earlier: http://gravityandlevity.wordpress.com/2011/02/02/who-am-i-to-say-whats-quantum/ When I was first introduced to quantum and particle physics I thought that from there you must be able to eventually get to the mechanical models which Newton etc developed.

Re: Is a university degree in the UK worth the money?

As has been stated above, it depends on the degree, some degrees have seemingly no value at all, media studies being the prime example, Beer brewing being another good one (although at least it ends up with something really worthwhile at the end!). A lot of degrees seem to be in subjects for which t...
