Serving the Reich: The Struggle for the Soul of Physics under Hitler

While several German religious leaders, writers and artists, industrialists and politicians mounted strong opposition to Nazi rule at great personal cost, sometimes of their lives, there was nothing comparable to be found in German science.

I stumbled upon the book thanks to this article that mostly dealt with the effort of constructing an Aryan version of Physics. What an interesting book. By using the stories of giants like Max Planck, Peter Debye and Werner Heisenberg during the Nazi rule the author explores the apolitical stance many scientists used to have (and depending the field continue to adopt) on the results of their work and the repercussions of them being used. Planck remained glued to the Fatherland regardless of who was ruling it (and whether being true to the Fatherland), Debye tried to walk though the rain without getting wet and Heisenberg with the arrogance that came with his ability tried to rebuild German Physics by assuming the role of its curator.

Together with these we learn of the noble stance by Max von Laue and Fritz Strassman  (“I value my personal freedom so highly, that to preserve it I would brake stones”) and the grey stance of the rest who stayed and did science within the regime. Even Lise Meitner and Debye left at the very last moment they could. Correspondence between many prominent scientists from the beginning of the Nazi rule till after WWII is also included. Very interesting points of view and commentary of the situation these people were in.

While you cannot completely enjoy the book without remembering your Physics, you will highly enjoy the questions of ethics and moral compass that it poses. I know it troubled me and it makes me answer questions about the work I am doing and the sector it applies too daily. And DevOps is not exactly science yet.

While the stories we read about for 11 or so chapters serve largely as a preamble to the fantastic epilogue on Science and Ethics, they do describe the situation we are in today and questions we need to answer. Prior to reading the book I used the get a bit sad when a scientist or an engineer I admired failed me on other standards that I supposed they were concurrently holding. I do not get sad any more. Within the realm of politics they are equally fallible like the rest of us.

The Expert Beginner

I found out about the Expert Beginner book from Avdi Grimm’s newsletter. It is a small but discomforting book (a series of blog posts turned into a book) that I believe anyone in programming, systems administration or DevOps arena must devote some hours to read. Its basic premise is the following extension of the Dreyfus model:

The Expert Beginner trap
The Expert Beginner trap

While the book is a guide on how to spot and avoid Expert Beginners (people who believe they have mastered all there is to master in their field and anything beyond what they already know is useless), it also serves as a guide to spot when you start emitting Expert Beginner signals yourself.

Do yourself a favor and read the book. Especially if you consider yourself a guru, ninja or rockstar of something. It will only cost you two hours.

A very British coup

There had been no tanks on the streets. No one had gone to the firing squad […] It was a very British coup.

I found out about “A Very British Coup” while searching for the origins of House of Cards. A very fascinating novel that deals with the complexities of governance. With a clear depiction of all the forces in power that collide, how and why.

Do you happen to know of a country in the Western World with a leftist government? That dislikes the IMF, the EU and NATO? That seeks funding from alternative sources? Then you should read this book, even though the ending was not of my taste. The novel had to end somehow anyway. Come to think about it, no, I like it how it ends. It reminded me of 1984.

Rock Breaks Scissors: A Practical Guide to Outguessing and Outwitting Almost Everybody

I have to admit, I bought Rock Breaks Scissors: A Practical Guide to Outguessing and Outwitting Almost Everybody because of the title. I was between this and Fortune’s formula.  I thought how can one write a book about rock-paper-scissors strategies? Would that include lizard and Spock also?

It turns out there’s only one chapter about the game. The book starts really strong, with Claude Shannon’s outguessing machine and how it worked. It then continues with a bit of Benford’s Law and Nigrini‘s work (and I am both a fan of the Law and of Nigrini’s book). Next is some excursion in Madoff‘s scheme and how it could have been detected had someone paid more attention to the numbers.

Afterwards the book becomes increasingly boring to me as it offers some advise on how to outguess office pools on bets I am not really interested in (like American football, NCAA and picking the Oscar winners). With that comes a so much dumbed down treatise on randomness that is becomes annoying to the point that I sometimes wonder whether Poundstone himself understands it.  And all that just to disprove the hot hand feeling that sometimes players feel. Yes, there is no hot hand. No, let them believe it there is. You cannot beat the belief by serving a dumbed down treatise on randomness. You’re making it worse.

Finally, the book finished with some work on the stock market. After several pages with a particular long-term investment example the author finally admits that “nobody invests for 132 years” and then proceeds to offer some advise that fits a lifespan better. Well, I do not like fillers like this when this is supposed to be an advise book.

A US audience might be happier with the book. What is damaging to me though, is that I need to look elsewhere for the history of the Kelly criterion (which is the subject of the other book from the same author that I was thinking about buying).

The Mathematics of Love

A friend passed me his copy of “The Mathematics of Love“, a book that uses mathematics in order to help you choose your strategies in the quest of finding love. Years ago I had stumbled upon this blog post by Mike Trick on finding love optimally. The same subject is covered in Hannah Fry’s book also.Things like the Drake equation, one night stands and online dating strategies get the spotlight too.

And you will laugh a lot. Knowledge of Mathematics is not a prerequisite.

The Martian

I first heard about The Martian at the Engineering Commons podcast. Mark Watney, a Botanist / Mechanical Engineer is presumed dead from his mission crew on Mars while they evacuate base during a sandstorm.  But as luck has it he survives and finds himself in the most hostile environment a human has ever endured.

Compared to what he has to face just to stay barely alive, any “survivor” reality show that you may have watched on TV is like a walk in the park. Science and Engineering save his life, even though sometimes he is lucky to stay alive in the series of hardships that face him.

Science and Engineering I get, but the sheer mental power and focus that is needed in order to stay alive in the most extreme environment for who knows how many days in an effort to just make contact back home and wait for who knows how long before a rescue mission reaches you, this is for me the dominating element of the novel.

Time to watch the movie now to get a better visual on some of the contraptions Watney devised during his reign on Mars.

Red Moon Rising: Sputnik and the Hidden Rivalries that Ignited the Space Age

Up until a month ago I never knew about the book. Good friend Nikos mentioned it over beer. I was sold on it immediately and bought the kindle version.

I’ve read two more books that cover a lot of the political and technological situation of this era (that is when Eisenhower and Khrushchev held the helms). Where Wizards Stay Up Late about Internet’s prehistory and even more Red Plenty provide angles on what was happening in the US and the USSR at the time.

Among all the people who know who von Braun is, how many have ever heard of Korolev? A man whose name was a state secret? What was it that made him sell the Sputnik to the Premier where in fact he demanded ICBMs? And why did the USSR had such a pressing need for missiles? What was the engineering gap that the two superpowers wanted to bridge? How did the military-industrial complex, or big egos, ambitions and personal rivalries affect the space race? Because nothing was done in the name of science.

If you are like me and remember the SALT II and the SDI here is a glimpse on why these ever happened. The book comes with a lot of notes if you want to delve more into the history, biographies, physics, engineering, politics or even economics of rocketry. The book is literally a launchpad to many directions itself.

PS: How were trajectories calculated without computers? Would you be able to fly a “steampunk” drone today with a slide-rule like they did with their rockets? Think about that.

Μια ιστορία με τον Boole

200 χρόνια σήμερα από την γέννηση του George Boole (σε περίπτωση που δεν καταλάβατε το σημερινό Google Doodle δηλαδή) και θυμήθηκα μια ιστορία:

Κάπου 20 χρόνια πριν εξετάστηκε ένας φίλος μου στην διδακτορική του διατριβή και κάποια στιγμή φτάνει η ώρα των ερωτήσεων. Υπήρχε ένας μέλος ΔΕΠ που ήταν κάπως πιο επιθετικό στις ερωτήσεις (χωρίς να υπάρχει κάποιος ιδιαίτερος λόγος) και κάνει την κλασική ερώτηση:

– Και που μπορεί να είναι χρήσιμα όλα αυτά στον πραγματικό κόσμο;
– Τι να σας πω. Και ο Boole όταν έφτιαξε την Άλγεβρα του, δεν περίμενε να υπάρχουν ηλεκτρονικοί υπολογιστές!
– Τολμάς να συγκρίνεις τον εαυτό σου με τον Boole;

Για όποιον ενδιαφέρεται, An Investigation in the Laws of Thought.

You are a writer (so start acting like one)

I got You are a writer by Jeff Goins on a day it was given for free years ago. I got to read it over the weekend. I thought then, and I still do no now, that the book offers advice to people who write code too. Maybe because sometimes I believe that code is like a poem. So I will try to rehash advice I found useful here, since this seems to be one of the acceptable self-help books that have come my way.

While anyone can connect with anyone and put stuff out there, how does one gets noticed? By helping people. By relieving their pain. I’ve advocated answering one question per day on ServerFault (or StackOverflow, or whatever clicks to you), although I do not always practice this. I used to, though, years ago when mailing lists and newsgroups were the thing.

You need to build a platform. This blog is a platform. I post stuff here. Others do it with more success, for example John Sonmez who uses a variety of platforms (blog, YouTube channel, podcast, book) to publish his work (and he gives 90% of his work for free he said on Ruby Rogues). You make the platform and you establish a brand. Without a brand you are forgettable.

And you know what helps you not being forgotten? Networking does. Meaningful relationships do. Relationships that are mutual, matter to both parties and give you the opportunity to make friends and find mentors.

But nothing of the above makes any sense unless you are prepared to answer the following questions:

  • Am I serious?
  • Am I committed?
  • Am I prepared to be challenged?

Please take the time to sincerely answer these questions. And while you are at it, understand that you probably are not the best coder in the world yet. But you can become one. There is room at the top here.

Like one of the main characters in The Phoenix Project said, mastery comes through practice. And here Goins argues that the best kind of practice is done publicly. Interestingly GiHub seems to be our public place of practice.

While you’re at it, learn to estimate. Underpromise and overdeliver. Especially when you are part of a team. Like Goins writes, you have a gift. Someone is willing to work with you.

Go on! Practice.
