AWS Instance ip-172-31-32-45
Ran out of hard drive space in an afternoon. Investigated systematically.
Root volume: 7.8G total — healthy for an OS, irrelevant to the problem.
Actual culprits found:
~/.local/share/claude/versions — 450M of Claude Code installer versions accumulating across self-updates. Prunable.~/.local/lib/python3.12/site-packages — 311M of provenance paper dependencies: scipy (111M), numpy (42M), matplotlib (31M), PIL, lxml. Earned, not waste.~/.cache/pip — 96M. Safe to purge with pip cache purge.bootes-env virtualenv (82M) potentially double-carrying packages already in ~/.local. Worth auditing.Key commands developed:
du -h --max-depth=2 . | sort -rh | the workhorse |
ls -lh ~/.local/share/claude/versions/ | find the dead weight |
ls -d ~/.local/share/claude/versions/*/ | sort -V | head -n -1 | xargs rm -rf | prune old versions |
The most confounding fundamental constants — the ones that fall out of physics with no derivable origin
| Constant | Problem |
|---|---|
| Λ (Cosmological Constant) | Off by 10120 from QFT prediction |
| α (Fine Structure, ~1/137) | Dimensionless, underivable, Feynman called it a mystery |
| Hierarchy Problem | Higgs mass requires cancellation to ~34 decimal places |
| Strong CP Problem | θ < 10−10 for no known reason |
| Baryon Asymmetry | 1 extra baryon per 109 pairs. We are that baryon. |
| Three Generations | Why exactly three? Mass ratios: unknown |
| Coincidence Problem | Matter and dark energy equal right now, briefly |
| G (Gravitational Constant) | Least precisely measured constant. Resists. |
Standard Model free parameters: 19. With neutrino masses: 26.
Not thematic groupings — structural ones. Constants that are probably the same mystery.
Catastrophic cancellation in two sectors. One solution solves both.
Inverse twins of the same broken symmetry.
Gravity specifically refuses both precision measurement and correct prediction. Probably the same failure.
Stands alone. The isolation is the clue.
The constants aren’t ordered by a higher power — they settled
The constants aren’t ordered by a higher power — they settle where they are because some transformation was applied to the initial conditions dataset. A higher-order constraint, possibly infinite in variety, acts like a guided pachinko board. The universe clicked into this attractor.
This makes 19 free parameters feel prime-like: irreducible only because we haven’t found the right coordinate system. Mendeleev had the same problem with elements until quantum numbers arrived.
Base-10 is suspicious. But primes are base-independent.
The right question: change the number system, not just the base.
Significant figures of fundamental constants, checked for primality
| Constant | Value | First 3 Sig Figs | Prime? |
|---|---|---|---|
| α−1 | 137.036 | 137 | PRIME |
| Electron mass | 9.109 × 10−31 kg | 911 | PRIME |
| Z boson mass | 91.1876 GeV | 911 | PRIME |
| Proton mass | 1.6726 × 10−27 kg | 167 | PRIME |
| SM free parameters | 19 | 19 | PRIME |
911 appears at two completely different energy scales — the electron (a fermion) and the Z boson (a weak force carrier). They are not obviously intimately related. Both prime. Same digits.
This analysis is base-10 dependent. Which remains suspicious.
All of this happened on an AWS instance with a full hard drive.
