Review: Why Time Flies: A Mostly Scientific Investigation

Why Time Flies: A Mostly Scientific Investigation by Alan Burdick
My rating: 3 of 5 stars

I was surprised to learn that all cesium clocks do not agree so an institute takes the data from the clocks and comes up with a time for all them to be set. Something like that. I thought that all cesium clocks all kept the same time. I think that are called cesium clocks. This book also made me think about the present. Is the present this second, a minute, an hour, a day, a year. Reading about experiments on people and animals was also interesting. I thought this book was OK.
