physical principles. Quanta
magazine, February 2019. Discusses publication
51 below (with Lluís Masanes and Thomas Galley), and

Medicine Network (yes, that's somewhat
surprising...), phys.org,

and others. Note that our work builds very strongly on
earlier work, ideas, and insights by Lluís Masanes,

This ‘zero-worlds’ theory might just be crazy
enough to be true. Interview
with "Essentia Foundation", July 2021, on my approach
summarized in paper 54 below. See also the New
Scientist title story of November 2017, and New
Scientist, January 2020 on "reality". There is
also a Less
Wrong blog post and this FQXi
article from January 2019, and an article in the
Israeli newspaper Haaretz.
For a first introduction to this approach, feel
free to have a look at this
seminar talk on YouTube. Further posts include
one by Ian
Durham (FQXi) and a mention on a blog on Learning
Machines.
- Our results on the Berry-Keating conjecture
(paper 43) have been greatly exaggerated by some media
(e.g. the
Wire), which in turn has led to criticism (e.g.
here).
To clarify: no, our work will almost certainly not
lead to significant progress on the Riemann
conjecture! But we think it is an interesting insight,
and its main observation is fully
mathematically rigorous. See also Nature
Physics, the
Reference Frame, phys.org,
Quanta
magazine, Spektrum
der Wissenschaft.
- Quantum perspective. New
Scientist, February 5, 2022. Describes our
result (publication 40) on deriving the Lorentz
transformations from properties of quantum
communication, and how they have inspired recent work
by Flavio Mercati and Giovanni Amelino-Camelia.
- Why space has exactly three dimensions.

Scientist, September 25, 2013. Discusses some
approaches towards this question, including our
publication 32 below.

amazing result.
- And thus the quantum. Nature

features our publication 25, where we show that the
Hilbert space formalism of quantum theory can be

physical/information-theoretic postulates.

Science writing by myself (about work by
others)
Early research before university
- Experimental disproof of an alleged antigravity
experiment ("Schnurer's experiment"), with
Josip Milanovic and Franz-Josef Schmitt (1999).
At that time, a popular German TV broadcast claimed
that a superconductor could yield an antigravity
effect in a simple experiment. Thus, we went to the
lab at University Erlangen and reproduced the
experiment. We found that Schnurer seems to have
misinterpreted a simple buoyancy effect.
- "Fractional sums": how to add a non-integer
number of terms (around 1998).
This idea led to several publications with Dierk
Schleicher (for example this one),
and made the first prize at the German youth science
fair "Jugend forscht" 1998 in mathematics and computer
science, together with an exceptional prize by the
Federal President.
- Higher-order arithmetic operations, and
non-integer iteration of functions (1994-1995).
The main idea is written up in a little document here. It made the
second prize at "Jugend forscht", and an exceptional
prize by the Federal Chancellor.
