Flutterby™! : Cow tipping: 231%?

Dang it, next thing you know these academics are going to go telling people about prop wash, smoke shifters, and snarks: University of British Columbia researchers Margo Lillie and Tracy Boechler claim that "cow tipping" is impossible, at least when attempted by one person:

More specifically, "a cow of 1.45 metres in height pushed at an angle of 23.4 degrees relative to the ground would require 2,910 Newtons of force, equivalent to 4.43 people," according to Boechler.

Dr Lillie elaborated: "The static physics of the issue say two people might be able to tip a cow. But the cow would have to be tipped quickly — the cow’s centre of mass would have to be pushed over its hoof before the cow could react."

Clearly their model was more complex than simply considering a spherical cow of uniform density.
