I'm a student at FER, Croatia. Interested in maths, biology, and AI. It's fascinating how optimising over combinations of shape production (proteins)
led to intelligence which we are still figuring out.
Currently: reading my favourite writers Henrik Karlsson, Sasha Chapin, Celeste, Scott Alexander. Working on a quasi-startup.
Trying to wrap intuitions around RNA folding.

2026-03-30 Rebuilt personal site from scratch. Libre Caslon is my favorite font.
Rabbit hole w Claude on stomach acid, RuBisCO, Purple Earth hypothesis.
Life works on a basis of ~50 molecules (nucleic & amino acids, ATP, sugars, essential lipids), that enzymes can work with & modify really well.
Attended an AI Business process automation presentation by Plavi Tim, INA 2026-03-31 Coffee talk: what pharmacy does, emotional books to read & my fav writers.
Stohastic processes; lots of questions about marginals and conditioning
Attended a long and sprawling 6 hour student association voting sesh. 2026-04-01 Bash scripting fun!
Stretching Claude code to do crosschecking from 50 PDFs and a spreadsheet, works!
Hosted house party, with 40min "Why I like San Francisco & rationalism" presentation.
- Topics like liking unorthodox things, how people dream there, optimize, worldmodels,
you can just do things etc. 2026-04-02 Early trials into a custom trading/hedge fund design, trading learning
Was generally quite shocked about how little energy or will I had to do things
- Probably lack of sleep, bad start of day, etc.
- Music is my main productivity poison
Found out & told collegue I didn't do something I promised 3 weeks ago; as a consequence a gaint international competition event has to be delayed by [2 weeks, up to 2 months].
- Feel really bad about it :(; but I've had a nonconsistency failure mode I still haven't gotten rid of. (+37 words) read more 2026-04-03 Very much underslept because of student org meeting yesterday.
- Was sluggish throught the whole day
- Too much time on substack (although excellent writing)
Didn't do much except shuttling papers to an NPO office :/
Fixing mistake from yesterday (while tired...) 2026-04-04 Another generally lazy day: too much time watching films & Substack.
Sending emails to fix my previous mistake still.
Felt like everything after college was more surface level, like I was improving more until 19.
- Realised I'm not actually playing *this game* right. I've fallen into the gifted trap. Grown complacent, not challenging myself, not strong enough of a work ethic. Drift under weak external structure.
- Everyone around me feels like they're missing the ball, NPCs at college. Super easy exams. (+129 words) read more Beliefs
- The world is power-lawy. Skills and experience compound, so over time the difference can be orders of magnitude.
This applies to money, love, friends, knowledge, et cetera.
- This is also why focusing on a handful of things is better than spreading yourself out.
- Modern life is centrally about fighting superstimuli and perverse mimetic adversaries.
This applies to small things we may not think of as addiction, as well as your social circle, as they
influence your state of mind.

Mathematics is the knowledge of abstract structures. Crucially, it explains combinatorial explosions
(responsible for understanding proteins), self-amplifying processes (exponential), and the broader limits on what
is logically impossible (can't have quantum mechanics without a Hilbert space).
- Math is Platonic, outside our universe, and necessarily holds for nearly all conceivable universes.*
-
Tutoring is much more effective than schooling. Many potentials are undercut because of the modern group nature of education.
- Tacit knowledge is the true moat, and holds entire companies together (TSMC).
- Some tacit skills, like charisma or being truly relaxed, can only be learned through mentorship or imitating successful peers.
- This is mostly just internalised knowledge from wrangling with problems, and knowing the details of certain parts of reality because you zoomed in on them.
-
Most of the differences in "intelligence" are in mental behaviour and mental routines when interacting with the world.
- Over time, the differences drift drastically because of wrong worldview building. That is why there exists a large gap.
-
You forget 95-99% of what you input. Spaced repetition is one way to not forget.
- You only really internalise very few pieces of advice or texts.
- The world has many asymmetric opportunities and edge cases you can use to your benefit. The trading concept of "alpha" is immensely powerful.
