I would love to have the opportunity to create  a home made project that allows you to send a small camera into the top regions of Earths atmosphere, take a photo of the curvature of the Earth and safely retrieve the picture.

This could be achieved by attaching a phone to a weather balloon and launching into the atmosphere. The balloon would rise to a point where it would eventually burst, from there the cargo would fall back to earth for safe retrieval. The tricky part would be the retrieval process. 

Definitely a project of a lifetime !

I recently watched a documentary on sky TV called 'The Vow'. An absolutely stunning insight into what it is to be a victim of a 'cult' following, much like the horrific Charles Manson followers. Unlike most shock documentaries, this one described the way people of all backgrounds can fall victim to the theories put forward by hypnotising leaders.  

What struck me was that the most susceptible people are those who go into it with an open mind, something which I believe is  the cornerstone to all scientific thinking. Nothing is ever fully understood, it is only known in layers of complexity. So the question that struck me was that of 'How do you know the difference between scientific knowledge and that with a hidden agenda?', something that effects most parts of modern life in such a  divided world.  

I'm reading a fascinating book by the MP David Lammy, called Tribalism. It offers an explanation to the rifts that exist in today's society, stretching through politics and everyday life. It seems to be a hangup left through evolution, when we were hunter gathers in groups of 100 or so that would see outsiders as a threat. As we become

more isolated in modern society we attach ourselves to groups and tend to see the

world through a collective perspective and shun outside views.

Certainly a bias to be considered in a changing world.
