sure you all know the Heaviside step function. It 's a function a bit' strange, you know when you are discontinuous the other functions you look a bit 'so ... "Yes it is true they are not differentiable at zero, I know .." and justifications of this type, when you are awkward questions, on your differentiability for example.
Although this is useful for a lot of times .. I know the quality of people, or that function, maybe you should not be assessed as far as getting used to ... The fact is that today empathize with the Heaviside step function, that his sudden change from one state to another .. I wonder if she realizes, if she feels he is about to change the status ..
functions are used to shape reality. Ok reality does not exist, but when we said we wanted to do a model of reality, we were just implicitly stating that our operation was taking a picture of reality, give a representation, something that we look like, that looks like something that is not that much but we see in front of the eyes, something that serves to model, in this case, a passage between the condescension and exasperation.
The Heaviside step function of the extreme situations. A little 'as when you are training for ordinary differential equations and steps away from trying to understand all'esclamare pig god, between the general acceptance when it is proposed to use as a Liapunov function, instead of the usual ax ^ 2 + by ^ 2 or variants, something like the integral of a function of more cock something else. Or controls the height at which there is a generic box, perhaps the nearest classroom where you are, (first floor classrooms north) and you get a pat that was dug in a basement.
And still want to stay there with the heroin addict who screams so much at home because you expect only the trench.
During the battle of Stalingrad, the Soviets forced the civilians to leave the city, as a kind of hostages, civilians or combatants, they did it mostly because it seemed a gesture of defeat evacuate the city that bore the name of Stalin.
I've always found a very rude gesture.
