Black Hole Physics API

salutare 4,656 Abbonati

Black-hole general-relativity maths as an API, computed locally and deterministically. The radius endpoint computes the Schwarzschild radius r_s = 2GM/c² — the event horizon of a non-rotating black hole — from a mass given in kilograms or solar masses, together with the photon sphere at 1.5·r_s and the innermost stable circular orbit (ISCO) at 3·r_s; the Sun would have an event horizon about 2.95 km across and the Earth about 9 mm. The time-dilation endpoint computes the gravitational time-dilation factor √(1 − r_s/r) at a distance r from a mass — a clock deep in a gravity well ticks slower than a far-away clock, and at the horizon time appears to stop. The hawking endpoint computes the Hawking temperature T = ħc³/(8πGMk_B), which is higher for smaller black holes, and the evaporation time, which scales as the cube of the mass — a solar-mass black hole would take about 10^67 years to evaporate. Masses are in kilograms or solar masses and distances in metres, using G, c, ħ and the Boltzmann constant. Everything is computed locally and deterministically, so it is instant and private. Ideal for astrophysics, cosmology, science-communication, simulation and education app developers, black-hole and relativity tools, and physics teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is general-relativity black-hole physics; for special relativity (Lorentz factor, E=mc²) use a relativity API.

Tidal Forces API

Tidal-physics and gravitational-dominance astrophysics as an API, computed locally and deterministically. The tidal-force endpoint computes the tidal (differential) acceleration that stretches a body, a = 2·G·M·r/d³, from the primary mass, the radius (half-size) of the affected body and the centre-to-centre distance — and the force if a body mass is given; tidal effects fall off as the inverse cube of distance, far faster than gravity's inverse square, which is why they matter only close in. The roche-limit endpoint computes the Roche limit, the distance inside which tidal forces tear a satellite apart, for both rigid bodies, d = R·(2·ρM/ρm)^(1/3), and fluid bodies, d = 2.44·R·(ρM/ρm)^(1/3), from the primary radius and the two densities — Saturn's rings sit inside its Roche limit. The hill-sphere endpoint computes the Hill-sphere radius, r_H ≈ a·(1−e)·(m/3M)^(1/3), the region where a body's own gravity dominates so it can keep moons, from the orbital distance, eccentricity and the two masses. Masses are in kilograms, distances and radii in metres and densities in kg/m³, with G = 6.674×10⁻¹¹. Everything is computed locally and deterministically, so it is instant and private. Ideal for astronomy, astrophysics, planetary-science, simulation and education app developers, ring-system and moon-stability tools, and physics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tidal and gravitational-dominance physics; for Newtonian gravity use a gravitation API and for orbital periods an orbital-mechanics API.

API de Magnitud y Distancia Estelar

Matemáticas de magnitud y distancia estelar como una API, calculadas local y determinísticamente. El endpoint de magnitud aplica el módulo de distancia, m − M = 5·log₁₀(d/pc) − 5 — proporciona dos de los siguientes: magnitud aparente m, magnitud absoluta M y distancia, y devuelve el tercero, con la distancia en pársecs, años luz y unidades astronómicas (la magnitud absoluta es la magnitud aparente que tendría una estrella a 10 pársecs). El endpoint de flujo aplica la relación de Pogson para convertir una diferencia de magnitud en una relación de brillo, F₁/F₂ = 10^(0.4·(m₂ − m₁)), donde cinco magnitudes equivalen exactamente a un cambio de cien veces en brillo — a partir de dos magnitudes, una diferencia de magnitud o una relación. El endpoint de paralaje convierte un ángulo de paralaje en una distancia, d(pc) = 1 ÷ p(arcosegundos), y viceversa, el método geométrico detrás del propio pársec. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de educación astronómica, planetarios, observación de estrellas y ciencia, herramientas de observación y astrofísica, y enseñanza STEM. Cálculo puramente local — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es magnitud y distancia estelar; para mecánica orbital usa una API orbital y para distancias de círculo máximo en la Tierra una API de geo-distancia.

Chimney & Flue API

Chimney and flue sizing maths as an API, computed locally and deterministically — the draft and dimension numbers a stove installer, sweep or builder runs so a fire pulls cleanly and safely. The flue-size endpoint gives the minimum flue cross-section for a fireplace opening: at least a tenth of the opening area for a square or rectangular liner, a twelfth for a round one (which draws better) — a 36 × 30 inch opening needs about 108 square inches of rectangular flue, or a 10.7-inch round. The draft endpoint gives the theoretical draft from the stack effect, ΔP ≈ 3465 × height × (1/T_outside − 1/T_flue) with temperatures in kelvin, so a 6-metre chimney with 200 °C flue gas on a freezing day pulls about 32 pascals (0.13 inches of water column) — taller and hotter draws harder. The height endpoint applies the 3-2-10 rule: a chimney must finish at least 3 feet above where it pierces the roof and at least 2 feet above anything within 10 feet, whichever is higher. Everything is computed locally and deterministically, so it is instant and private. Ideal for hearth and stove-installer apps, chimney-sweep and inspection tools, building-design calculators, and DIY-safety sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational estimates — verify against your appliance listing and adopted code.

Fishing Tackle API

Angling and tackle maths as an API, computed locally and deterministically — the three numbers that decide how a reel is spooled and a lure is fished. The line-capacity endpoint works out how much line of a different diameter a reel will hold: line lies on the spool by cross-sectional area, so capacity scales with the inverse square of diameter — a reel rated for 100 yards of 0.30 mm holds about 73.5 yards of thicker 0.35 mm, or nearly 140 yards of a thinner 0.011-inch braid. The sink-time endpoint gives the countdown to fish a lure at depth: time = depth ÷ sink rate, so a minnow that sinks a foot a second reaches ten feet on a count of ten. The drag endpoint sets the reel: about 25–33 % of the line's breaking strength measured at the rod tip — a 20-pound line wants roughly 5 to 6.6 pounds of drag, enough to let a fish run before anything snaps. Everything is computed locally and deterministically, so it is instant and private. Ideal for fishing and tackle apps, reel-spooling and gear-shop tools, angler trip-planners, and learning sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Unit-agnostic — keep your units consistent; rules of thumb, conditions vary.
