Oh dear, little Pinguin! Einstein's theories are way beyond my mental capabilities. I will never understand how someone at the beginning of the last century was able to develop these theories. Why for heavens sake are you little guy linked to Einstein. And sorry that I did not read your mission statement when we found you in this cache. Hopefully someone else brings you to a cache close to the GSI here in Darmstadt, which is definitely the right place to go for you!
