The half-hole

The Nobelprice in Physics was awarde today to the three british researchers David Thouless, Duncan Haldane and Michael Kosterlitz for their contribution of the research on ultrathin materials, the plains of the mattter. They used a certain tool, the topology. What I didnot realize so far is that topology is the science of holes: You can not transform a hoop into a ball, the former has a hole in it, the latter not. There are structures with 0,1, 2, 3, … holes which can not be transformed into each other. Interesting.

The Nobel juror Thors Hans Hansson explained this and mentioned that holes can only be whole-numbered. There are not half-holes. This reminded me of Kurt Tucholsky, German pacifist and writer in the first part of the last century who published under the pseudonym Peter Panther a “Zur soziologischen Psychologie der Löcher“, the only English translation I found on this website: http://www.theavanwoland.com/thea_tul_text.html.

I dare to publish some lines from there:

The Philosophic Sociology of the Hole ( by Peter Panther alias Kurt Tucholsky)
A hole is there, where some-thing is not.
The hole is  the eternal companion of the non-hole.
Hole on it’s own, there is no such a thing, sorry.

If there would be something everywhere, there wouldn’t be any hole,
but there wouldn’t be any philosophy either and certainly no religion, as such that comes out of it.

The mouse couldn’t live without it, neither does man.
It’s the last chance for both of them,  when they are threatened by
the material.
Hole – is always good.

The hole is the fundament of social order and that’s how society is…

Tucholsky would have liked this Nobel prize very much.

The book has finally been published. This version is the translation of our German book 3rd edition, with some updates due to very recent new developments. The part on Juvenile Hormones was critically read by Prof. Riddiford from the USA and is thus up-to-date. I like to say thank you so much to numerous colleagues who have contributed articles that this book could be written in its present form. It has been a pleasure to work with the Springer people who produced the book. Thank you to Dr. Britta Müller and Martina Himberger who took the burden to defend and to publish this book. It has been a continious pleasure to get the help form the tex-community where I got posed many questions to make the book look nice. Among those who have contributed tremendously by reading large parts of the German and English version are my wife Beate who helped with the original version, Prof. Hubertus Jarry  in Göttingen and Prof. Ashley Grossman now in Oxford who encouraged me to go on with the English version after reading the 80 % translated and uncorrected intermediate. When you find this book enlightning, please write to me. If you think that issues are wrongly presented, please write to me that I improve the book in a next version. It has been a pleasure to prepare this book, it is an even greater pleasure to see it coming out.
