Castlerigg Stone Circle near Keswick must be one of the earliest scientific sites, if you think about it. Scientists make careful observations and record them. These ancient people made careful observations about the movement of the Sun through the seasons and recorded it. It will be impressive if modern scientific findings are as durable. The study of time is one of the most important areas in Physics. What exactly is time? One of my teachers said that it was the thing that meant that two objects could occupy the same space. (Think about it!) Isaac Newton thought that time was independent of space - as if there was a big clock sat outside the Universe so that there is the same time everywhere. Einstein showed that isn't true. First, light has a fixed speed, so that when I look at the Sun, it is like it was 8 minutes ago because that's how long it takes the light to get here. What does that do to the concept of NOW? Secondly, Einstein showed that time can be stretched if you travel fast. A second takes longer if you are travelling faster. To understand this, read Einstein for Beginners. It's in the school library. See my other blog for details: http://www.idareyoutoborrow.blogspot.co.uk/2012/10/einstein-for-beginners.html
