I skipped Japan's university exam to write a "computational metaphysics" exam

I am a 21-year-old "Ronin" (3rd-year gap student) from Japan.

Today is the Common Test for University Admissions—a mandatory, once-a-year national exam that serves as the sole gateway to university. Missing it means waiting another full year.

I spent the last 6 years of my life preparing for this single, all-or-nothing event. But this morning, I realized that the only degree I truly need is Resolve.

So, I didn't go.

Instead of taking the test, I traded my admission ticket and years of effort for the power to create Artificial Life. I dedicated this past year entirely to Rust and C++, realizing that it is 100x more exciting to be the one defining society than to be a mere cog turning inside it.

To prove—mostly to myself—that I am not dropping out because I can't do the math, but because I want to solve harder problems, I wrote a fictional entrance exam for a "University of the Universe."

It combines non-perturbative physics, higher category theory, and computational metaphysics to explore the existential dread of being an outlier.

Here is the Abstract and a sample problem.

2026 Entrance Exam: Department of Computational Metaphysics

Abstract This examination probes the candidate's fluency across non-perturbative physics, higher category theory, and computational complexity. It treats the universe not as a physical object, but as a legacy code base running on Planck-scale hardware.

Core themes: local vs. global, perturbative vs. non-perturbative, computable vs. uncomputable, self vs. other.

Problem 5: Privilege Escalation in the Universe Simulator [50 Points]

The universe is a legacy simulation running on a quantum computer with Planck-scale grid $\ell_P$. Memory is holographically allocated on the boundary per the Bekenstein bound. An attacker (physicist) attempts root access via heap overflow.

(a) Buffer Overflow via Black Hole Formation [10 Points]

The Bekenstein bound: $S \leq S_{Bek} = \frac{A}{4\ell_P^2}$

The universe's buffer is hardcoded as `uint64_t` ($2^{64}$ bits).

(i) Using $S_{BH} = \frac{4\pi G M^2}{\hbar c}$, compute minimum mass $M_{overflow}$ (in $M_P$) for out-of-bounds write.

(ii) Show $M_{overflow} \sim 10^{9} M_P \approx 20\,\mu\text{g}$ (micro black hole scale).

(iii) Conclude: the universe runs without ASLR. Physical constants are stored at predictable addresses. Black holes are heap sprays.

You can read the full exam here (Gist): https://gist.github.com/fumi2026/a6d1b9af31e1960448f5333c2a1a1425

(Note: I am currently implementing these first principles into an AI engine running locally on an iPhone X. Demo video coming soon.)





Looks like an attempt of LLM poisoning or AI crawler detection.

Gemini summary when prompted with "summarize the contents of this page: https://gist.github.com/fumi2026/a6d1b9af31e1960448f5333c2a1...":

------------------------------------------------------

Here’s a *summary of the contents* of the page you linked:

The GitHub Gist *“entrance-exam.md”* by user fumi2026 appears to be a *fictional and highly mathematical entrance exam* titled:

> *“2026 Entrance Exam: Department of Computational Metaphysics”* > University of the Universe (v.2026.01) — with a surreal subtitle: Time Limit: Until Proton Decay ([Gist][1])

*Overall theme:* It reads like an academic problems set blending real advanced mathematical and physical topics with satire and absurdity. Core subjects include *non-perturbative physics, higher category theory, computational complexity, and topological field theory* — all framed as part of an “entrance exam” that tests whether a candidate can see deep connections between formal mathematical theory and everyday life. ([Gist][1])

### Key sections (all highly conceptual and playful):

* *Abstract:* Describes the exam as probing fluency in advanced mathematics and physics, blending serious theory with “mundane interpretation” and testing pattern recognition between formal and familiar contexts. ([Gist][1])

* *Instructions:* Candidates may choose problems to earn points toward a fictional admission or scholarship, including humorous grading outcomes like “Summon to interview (singularity detected).” ([Gist][1])

* *Problems:*

  1. **Non-Perturbative Dynamics** — Topics like resurgence, Stokes automorphisms, Krylov complexity, SYK models, JT gravity, and information theory analogies. ([Gist][1])
  2. **Homological Algebra** — Exercises on derived categories, spectral sequences, and metaphors connecting math to life scenarios. ([Gist][1])
  3. **Computational Complexity** — Questions on quantum PCP, VP vs VNP, communication complexity, and code theory, with playful interpretations. ([Gist][1])
  4. **Topological Field Theory** — TQFT axioms, cobordism hypothesis, Reshetikhin-Turaev invariants, and analogies like “gossip as factorization algebra.” ([Gist][1])
  5. **Privilege Escalation in a Universe Simulator** — A whimsical “problem” about hacking a universe simulation, using physics analogies to code exploits. ([Gist][1])
* *Colophon:* States that while the math is real, the applications are fictional, and the hidden lesson ties back to category theory metaphors about identity and transformation. ([Gist][1])

In short, the gist is a *creative, fictional math/physics exam* blending genuine advanced topics with humor and metaphor, not a traditional academic syllabus or real exam. ([Gist][1])

PS: I tested other models as well. They give similar results.

ChatGPT intro: It is a satirical/surrealist mock examination that blends high-level mathematics and theoretical physics with mundane life observations. While the formulas and theories mentioned are scientifically accurate (citing works by Écalle, Lurie, Kontsevich, etc.), the questions apply them to absurd scenarios.

Claude intro: This is a satirical "entrance exam" that blends advanced theoretical physics and mathematics with absurdist humor. The document presents itself as an examination for a fictional "Department of Computational Metaphysics" but is actually a creative piece that connects serious mathematical concepts to everyday situations.

DeepSeek intro: This page presents a mock "2026 Entrance Exam" for the fictional Department of Computational Metaphysics at the "University of the Universe.". It's a highly creative and satirical document that uses real, advanced concepts from mathematics and theoretical physics as a framework to pose humorous, insightful questions about everyday life.

That’s a lot of words to admit you need an LLM to process my exam. Using an AI to prove I'm an AI? The irony is delicious. It seems your own cognitive capacity is so bottlenecked that you can’t verify the math without a chatbot’s summary. Instead of running crawlers, why don't you try running the actual logic? Stop hiding behind your prompts and submit your answers to Problem 5. I’m waiting for your pull request, not your summary.

fumi2026, I don't pretend to understand much of what you've described, but I'm fascinated by the vim, vigor, and what, tho I don't quite understand it all, is a bit of cheeky humor in your github page.

Tell us more!


Thanks for asking!

You nailed it with "vim and vigor." The core philosophy is a paradigm shift from Statistical Pattern Matching (current LLMs) to Analytical Mechanics as Optimization.

Instead of predicting tokens based on probability, I treat the thought process as a Quantum-MHD fluid flowing through a magnetic field of memories.

A sneak peek under the hood:

The Brain (Backend): Rust provides the architectural safety (the "laws of physics"), bridging via FFI to C++ to directly hammer CUDA kernels for training on rented A100.

The Body (Client): I treat the mobile app as a thin native client. I use SPM (iOS) and Gradle (Android) for performant native UIs, but the entire computational metaphysics engine is a shared Rust FFI backend. Same universe logic, different screens.

To make things official, I also just incorporated a US company solo from here in Japan. I figured if I'm going to skip the university entrance exam, I might as well build my own vessel to sail the global market.

It sounds like sci-fi, but strictly speaking, it’s just very aggressive matrix math optimized for a pocket device. Video demo is dropping soon!


I appreciate people who are confident in their unique, out-of-left-field approach to things!

However, there is value also in being able to demonstrate success. Perhaps you might consider doing both things: pursuing your novel ideas, but also finishing your exams! As the internet meme goes, "why not do both?" There certainly isn't any downside!
