JJ Thomson was awarded the Nobel Prize for Physics in 1906 having proved that electrons are particles. 31 years later, his son, GP Thomson, was awarded the Nobel Prize for proving that electrons are waves. They
were both right.

Time

1- Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time. Millions of years ago, a day on Earth will have been 20 hours long. It is believed that, in millions of years time, a day on Earth will be 27 hours long.

2- The length of time it takes for Earth to orbit the Sun is 365 and a quarter days. To make up this extra quarter which isn't counted at the end of a year, we have an extra day every four years on 29th February. This year, 2008, is a Leap Year. The next Leap Year will be in 2012.

3- A day on Mars is about half an hour longer than a day on Earth.

4- There is no time at the north/south pole as all time zones fall in to one place making it impossible to define the time !!!

5- Every day is about 55 billionths of a second longer than the day before it
