Time

Today I am writing on Time. I have an idea since 1992, to teach calculus in high school with finite difference equations to forego differential equations.

It is known that the ε and δ demonstrations are hard to grasp by novices. I believe that part of the problem is that these demonstrations are computer programs and are not presented as such.

We have to call a spade a spade to be understood. High school students have arithmetic and algebraic abilities, but they do not know how to program computers. When we tell them that calculus is studied with formulas, and never mention programs as essential, it only causes confusion.

Writing my didactic proposal I want to say something on Time.

The note below is about a group of theoretical physicists trying to come to terms with the concept of time.

Experimental results have already taught us that time is not what we believe it is. One of the biggest mysteries is CP violation. Cronin, and Fitch, got the Physics Nobel Prize in 1980 for this measurement. With the standard interpretation of time in theoretical physics, this result teaches us that past and future are not equivalent.

If at the microscopic level time has an arrow, and time passes according to the state of motion of the system under study, then we have a problem.

Some, like Julian Barbour, want to rid themselves of the idea of time altogether.

I believe that the key is, Information, with capital I.

Physics categories are space, time, and matter. The subject matter of this science is motion. Information is not among the categories.

I believe that until Information finds its place in Physics we won't be able to quantize gravity, and understand time.
