Talk Title: `What is time?'

Abstract: `Time' is something very familiar to all of us. But the physics of the XX century has discovered that time works quite differently from what we usually think. In this conference I will review what have learned a lot about the nature of time, but also the mysteries surrounding this notion that are still open. These mysteries are connected with many questions about the universe that are still open, like the fate of black holes, the nature of heat, the reason past is different form future, and the nature of our consciousness.

The talk is open for all and there is no registration required. Please let us know in advance of an intention to come with groups of students larger than ~10 persons, so to estimate attendance and ensure we have enough sitting space for all.
