READ IN ORDER, OR DON'TFirst,
the observer.
I am Omar Mishra. I write code that pretends to be the universe, then measure how well it lied. Keep scrolling. The nearest star would like a word.
Gravity does the work. I just take the credit.SOL · G2V · ONE STAR, EIGHT PLANETS, ZERO REVISIONS
ORBIT.
CHAPTER 02 · P. 11One timestep.
Then another.
An orbit is never solved, only approximated: the integrator takes a small step, commits a small error, and promises to keep it below tolerance.1 The trajectory above is being integrated by your scrolling. You are, at this moment, the timestep. Choose it wisely.
The Instruments
CHAPTER 03 · P. 19A working stack, like a good observatory, carries about fifteen instruments, and at least one is always invisible until the night everything breaks. Fifteen of mine are laid out below in the gravel. Sweep your cursor through the field and find the fifteenth.

The Observer
Formal training in physics and mathematics; informal training in staring at logs at three in the morning. Both continue.
Research Interests
N body dynamics, exoplanet detection, gravitational waves, and any problem that can be persuaded to fit on a GPU.

Errata
The universe simulated on this page is smaller than the real one. The author regrets the missing 1080 particles.
1 Symplectic integrators do not eliminate error; they make it orbit the truth instead of drifting away from it. This is also a workable life strategy.
2 No stock photos, no screenshots. Each plate in the catalogue is generated by this page when it loads: seeded randomness, a little trigonometry, and the same physics it depicts.
