This video does not offer an explanation, but asks several people the question and shows their answers.

The Earth spins on its axis, completing a full revolution every day. By why does it do this? One of the most common misconceptions in physics is the belief that constant motion requires a constant force. So many people believe there must be some force in the Earth (e.g. gravity, centrifugal force) that keeps it...

The video explains that as pressure is exerted onto the ice it melts and it is the liquid water, in contact with the ice, that makes it so slippery.

Planetary scientist, Professor Andrew Coates, explains why scientists look for the evidence of signs of past life on Mars.  He talks about the history of Mars and the current harsh environment on the planet. This video is part of a series of ten which look at the one of the elements of the European Space Agency’s...

This video explains the structure of DNA and the role of histones and methyl groups in deactivating one of the X chromosomes in a female.  The deactivation of one X chromosome is random. As mitosis reproduces cells, they may contain the X chromosome inherited from the father or the mother.  This can’t be seen in...
