First of all I want to apologize about my behaviour on last lesson.

I would like to explaine my behaviour.

On the last lesson we talked about philosophers and scientists of the past as Aristotle, Archimedian, Einstain etc. We talked about their contributions to development of science and contribution to society.

But when my teacher and my classmates began made mistakes about the inventions and contributions of this people I interrupted them rudely.

Einstain didn't calculate the speed of light and Archimedian didn't discovered the law of communicating vessels, and Aristotle didn't described the ideal society named "Utopia".

When I hear such errors I can't keep calm.
