That just means that nobody understands what a given qualification represents. Since the value of having a qualification derives entirely from that understanding, the more diversity you have in cirricula, the more it detracts from that value. Imagine if large employers had to ask not only what...
You're doing it again! You're quoting things that look like they back you up, but actually don't. :p
Row interchange preserves the system, but not the matrix. I proved that earlier - equal matrices subtract to form the zero matrix, and those ones - which do represent the same system - did not...
Oh dear, I think I get to the source-quotign thing now. :p
Intuitively, a field is a set F that is a commutative group with respect to two compatible operations, addition and multiplication, with "compatible" being formalized by distributivity, and the caveat that the additive identity (0)...
Calling for evidence is good, because it's not possible to acquire statistically significant numbers of anecdotes. :p
This, OTOH, IMO, defeats the whole point of tipping. You might as well say, "No tips are required," increase all the prices 15% and increase everyone's wages by the proportional...
The claim isn't that women are more attractive, but that they appear more attractive, because culturally, women in general place more importance on their appearance than men do.
The physicists' explanation is that the photon is wave-like, takes all possible paths (including through both slits) and that's why the two slits can affect the results. This doesn't make any sense with point-like, counterfactual definite photons.
I think it's a lot less reasonable to think that tipping is equal genderwise than it isn't. Even assuming that the "average" attractiveness is the same either way (which I doubt - I think culture means that women will appear more attractive on average) then there could reasonably be other...
