Carla Ravelli, welcome to Within Reason.

Thank you very much, pleasure being here.

I should tell our viewers that this is the second time we've tried to do this and there's an irony lurking in there somewhere.

You're the author of The Order of Time and I want to talk to you

today about the philosophy of Time. One of the most interesting things that you bring

people's attention to is the fact that, well, as I put it in an email to you, your time is not my time. We try to record this before, and I'd mistaken the time zones,

and so you were already an hour before I was, and it was was all bit messed up and we had to reschedule

and in my apology to you I said look I'm so sorry these these time zone mistakes to happen after all

your time is not my time so I suppose I should begin by asking. That's right we're not in the same time. Yeah do you think that I can be blamed for for being

unintentionally late for interview if time in fact does not exist in the people think in the way the people think it does.

Nice question.

Well, we, we, um, there is a subtle relation between the difference of time due to the time zones and the difference in times due to relativity effects.

This is a two different thing, right?. These are two different things, right?

We talk about two different things.

But nowadays, we easily get confused

about the relativity,

the relativistic effect of time and only once in a while like as we did we

get confused we got we get confused about time zones but there was a time in which time zones were extremely confusing for people.

It just didn't understand it. The first time the Board of Asco de Gama did the tour of the earth, it came back and there was a huge dispute about the number of days it took.

Because of course the number of days if you say put in London between departure and arrival of the boat is different than the number of days of that the boat that goes around the planet experiences the difference of one. You think for a moment it's pretty obvious.

But everybody was confused at the time because people were very much confused about time zones. You see, time seems completely intuitive and simple, but it's not. Yeah, I mean, that's a fascinating

completely intuitive and simple, but it's not.
