Today we visited the Dutch Resistance Museum. It was excellent and shows how brave some people were.
This little book was just one Euro, which is excellent value

The Fermi paradox
This is the apparent mismatch between the number of planets that should support intelligent life and the total absence of any evidence that intelligent life exists.To my knowledge we have been looking for about 60-70 years without any success.

Hotel window view
This is the view from our hotel bedroom in Amsterdam overlooking the Singel canal.
EchoLink
Not having access to my radios I tried listening to my local repeater by EchoLink. Imagine my surprise finding someone on it!

Amazing fact - human brains
Yesterday, I read that the capacity of the human brain has been estimated as 2.5 million gigabytes, which is huge. When you think of a lifetime of memories it has to be enormous.
It makes our computer memories look tiny by comparison. I wonder if they will work out how to create artificial memories as large one day? Imagine being able to store this much data! If possible, perhaps we could have "add on" memories to store, for example, a new language.
You could imagine that memory research based on neural networks (much like the human brain) is rich for exploration. I could imagine that in 50 years' time huge memories might be possible making those of today look tiny. I imagine that the US and Chinese governments are already working on this.
Imagine the computing power of these mega-computers working in parallel. Frightening.
