What if π could be read as DNA?

DNA is written in a four-letter alphabet. So is base 4. Turn the digits of π, φ, e, √2 and √3 into A, T, G and C, and they contain sequences that a cell could read as proteins. Is that meaningful, or just chance? This site lets you check.

The idea in four steps

Everything below is computed live in your browser, using the method from the paper.

01

Take the digits

The first 2,000 decimal digits after the point: π → 1415926535…

02

Write each in base 4

Every digit 0–9 becomes two base-4 digits. 7 → 13, 9 → 21.

03

Map to nucleotides

0→A 1→T 2→G 3→C, then keep the first 1,500 bases.

04

Read it like a cell

Find every ATG start codon, translate until a stop codon, and keep proteins of 5+ amino acids.

Explore a constant

Pick a constant to see its DNA, its open reading frames (protein-coding stretches) and the proteins they translate to. Click a protein to find it in the sequence.

Test it against chance

The key question the paper raises: do constants produce more or longer proteins than random digits would? Here we run the exact same pipeline on thousands of random digit strings and see where each constant lands.

Try your own number

Paste any string of decimal digits: another constant, a phone number, a date. Non-digit characters are ignored.

The paper

Mathematical Constants as Generative DNA Seeds: A Computational Hypothesis for Irrational Numbers as Protein Sequence Generators.
Mohcin Bajja, Independent Researcher, Khémissat, Morocco. Preprint v1.0, April 2026.

What it claims

When mapped to DNA through base 4, all five constants contain open reading frames and translatable proteins, with GC content around 29–32% and longest proteins of 40–73 amino acids. √3 gives the longest (73 aa); e gives the most diverse.

What it does not claim

No biological origin, no design. The hypothesis is computational and falsifiable: do constant-derived sequences differ from random sequences of the same composition? The paper asks the community to test it with random baselines, BLAST and protein folding tools such as AlphaFold2 or ESMFold.

Reproduction note. This site reproduces the paper's GC content and longest proteins exactly. The ORF totals computed here (one count per start codon across the three forward frames) are exactly one third of the totals in Table 1 of v1.0 (for example 30 vs 90 for π), which suggests each ORF was counted three times in the original script. The relative ranking of the constants is unchanged.
