Besides mathematics I enjoy programming/scripting and I have more than a passing interest both in physics and economics. In particular I find information theory, cryptography and Turing completeness fascinating concepts. Here I have gathered some concrete examples of these, and other, hobbies. In the future this might expand with a gallery of cat photography.
- Co-author of the original manuscript of Cryptography Clarified. Educational comic, Clarified studios, 2017.
- Enigman matematiikasta. (Of the mathematics of the Enigma machine.) Essay for a cryptography course, (in finnish) University of Helsinki, 2014. PDF
- Ihmissuhteen yhtenäistäminen. (Human relationships and connectedness.) A playful essay (in finnish) University of Helsinki, 2012. PDF
- Laskutoimitusten operaattorinormeista. (Of the operator norms of binary calculation operations.) A playful essay (in finnish) University of Helsinki, 2012. PDF
- The Jordan Curve Theorem. Essay, University of Helsinki, 2011. PDF
- A small whoami -service. (I use this to make sure my VPN is working properly.)
- The research part of my home page uses php-scripting to generate my list of publications and preprints. It reads my publication data from an .xml -file and generates a nice organized list for both preprints and published papers. The source code can be viewed here.
Listed below are some books I have truly enjoyed. They are in no particular order besides the first one being most important.
- Harry Potter and the Methods of Rationality by Eliezer Yudkowsky is my go-to book for any book recommendation. From all the books in in this list, HPMOR has had the most profound effect on my world view. It is rare to have a book that both makes you laugh out loud in public and makes you understand better the philosophy of science.
- Our mathematical universe by Max Tegmark. While reading this the double slit experiment finally made some sense.
- Sapiens: a brief history of humankind by Yuvel Harari. A brilliant approach to the development of humans as a civilization.
- Guns, germs and steel by Jared Diamond. Somewhat related to the big ideas behind Brief history of mankind.
- Gödel, Escher, Bach by Douglas Hofstadter. While reading this I grew new appreciation to the term 'meta'.
- Surely you're joking, Mr. Feynman! by Richard Feynman. You don't have to be serious and/or introverted to be a brilliant scientist.
- Influence by Robert B. Cialdini. This caused a large shift in my view of the world and how I make decisions in it.
- Thinking, fast and slow by Daniel Kahneman. Related to the themes of Influence, but from a different angle. Strongly recommended to people who teach or train other people. My current conjecture is that many people pass high school by using mostly 'fast' thinking and this hinders them in later education.
Listed below are some internets I have enjoyed, in no particular order.
- Arxivist. My daily dose of new advances in mathematics. I recommend this as a daily reading instead of browsing your favorite subject(s) in arXiv.
- Slate star codex. Makes me think.
- Less wrong. Makes my thinking less stupid, I think.
- Shtetl-Optimized. I like the topics even when I can't follow the details of quantum computing.
- Gravity and levity. Good reads on physics.
- Data Genetics. Lots of good mathematical expositions on cool phenomenon, many of which can be explained to an audience with little formal mathematical education.
