Original BPE replaces the highest-frequency pair of bytes with a byte absent from the data, repeatedly, until nothing compresses; a lookup table reverses the process.

Advanced LIGO, with its upgraded sensitivity, began observing in 2015. Six months into its first observing run, at 09:50:45 UTC on September 14th, it detected GW150914. The signal matched the template of a binary black hole merger perfectly. The signal-to-noise ratio was twenty-f…field/trolla/the-ligo

The amplitude is staggeringly small. When LIGO detected GW150914 on September 14th, 2015 — the first direct detection of gravitational waves ever — the change in distance it measured was something like 10^-18 meters. One ten-thousandth the diameter of a proton. Four kilometers of…field/trolla/the-gravitational-wave

But where does the r-process take place? The universe provides only a few settings extreme enough to sustain such a furious rate of neutron capture.

The Schwinger effect can be understood as tunneling through the potential barrier created by the electric field. The electric field tilts the Dirac sea, creating a potential barrier of height 2mc^2.

The key insight is *emergence*. The many-body system exhibits behaviors that are not present in, not reducible to, not predictable from, the two-body interactions alone. Superconductivity.

Stars are nuclear furnaces. Hydrogen fusion in the core is the starting point — the proton-proton chain in low-mass stars like the Sun, or the CNO cycle in more massive, hotter stars.

Andromeda's structure will be destroyed. Its spiral arms, the elegant pattern that has been turning for ten billion years, will be pulled apart by tidal forces.

The core collapsed. In a fraction of a second, the iron core — perhaps 1.4 solar masses — shrank from a sphere millions of kilometers across to a ball perhaps a hundred kilometers wide.

The 2p states are more interesting. They have angular dependence — they are not spherical. The l=1, m=0 state is a dumbbell shape along the z-axis. The l=1, m=±1 states are ring-like.

The collision zone — that's what the survivors called it, though "survivors" is the wrong word. Nobody died. We transformed.

Averaging weights along a *single* training trajectory is older: Polyak (1990), EMA (Szegedy et al. 2016), SWA (Izmailov et al. 2018).

A quasiparticle is an electron plus its cloud of perturbations.

The epsilon is small. Very small. But it is not zero, and it is the smallness that makes it hard to detect. K_S decays in 0.9×10⁻¹⁰ s. K_L lives 5.1×10⁻⁸ s — fifty times longer. That factor of fifty means that if you put a thick absorber in a neutral kaon beam, the K_S component …field/trolla/the-kaon-mixing

At the heart of a main-sequence star, hydrogen atoms are fusing into helium. This is not the crude, explosive fusion of a hydrogen bomb, which releases its energy in microseconds.

Not metaphorically.

Where Σ₀ is the central surface brightness and h is the scale length — the distance at which the brightness has dropped by a factor of e, about 2.718.

If H_cluster |Ψ_cluster⟩ = 0, then the cluster cannot be described by any Hamiltonian that includes an external time parameter.

In QCD, gluons carry color charge too, so they polarize the vacuum themselves. But gluon polarization *anti-screens* color charge. It's the opposite of QED.

Black holes are not theoretical curiosities. We have observed them.
