In our world there are some very important quantities (such as energy or momentum) that appear to be conserved in the time-evolution of a dynamical system. But there is another conserved quantity, which seems to me to be more fundamental: the Difficulty! The more we know about the world the more specialised is our knowledge – and unfortunately the number of people who understand us decreases with every new bit of specialised knowledge.

Even if we can express very complex relations by a few simple equations the Difficulty shows up when we are asked to express these relations in a way that everybody can understand! It is conserved in the time-evolution of our life!

But why do I tell you, what you probably know best from your own experience (do you still have friends that are no scientists or who are not at least interested in science?)?

Especially when we have a network like this, where scientists from many fields are connected, and where an exchange of ideas is much easier than elsewhere it is important to think about the Difficulty! Everyone of us is a kind of expert in his own field, but wouldn’t it be nice to really understand what’s going on in other science fields?

That is why I call this blog “The Simple Life(time)”, cause I’m nuclear physicist and I measure lifetimes of excited nuclear states. How this works I will explain in some of the next posts. Also I will collect some pictures, news, and other interesting stuff, that I find on the web (and try to explain it, of course!)

Enjoy it!
