API de Relatividad Especial
Matemáticas de relatividad especial como API, calculadas local y determinísticamente. El endpoint lorentz calcula el factor de Lorentz γ = 1/√(1 − β²) a partir de una velocidad (en m/s, km/s o como fracción de la velocidad de la luz β), y — dado un tiempo propio o una longitud propia — el tiempo dilatado Δt = γ·Δt₀ que mide un observador estacionario y la longitud contraída L = L₀/γ. El endpoint energy calcula la energía en reposo E₀ = mc², la energía total E = γmc², la energía cinética KE = (γ − 1)mc² y el momento relativista p = γmv de una masa que se mueve a una velocidad dada, reportando las energías tanto en julios como en electronvoltios. El endpoint mass-energy aplica la ecuación E = mc² de Einstein para convertir entre masa y energía en cualquier dirección, en julios, electronvoltios, megaelectronvoltios y kilovatios-hora. La velocidad de la luz es exactamente 299,792,458 m/s. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de educación en física, simulación, astronomía y comunicación científica, herramientas de relatividad y física de partículas, y enseñanza STEM. Cálculo puramente local — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es relatividad especial; para movimiento SUVAT cotidiano use una API de cinemática y para mecánica orbital una API orbital.

Isotopes API
Atomare Isotopen-Referenzdaten als API, basierend auf den NIST Atomic Weights and Isotopic Compositions. Für jedes bekannte Nuklid: sein Element (Ordnungszahl Z und Symbol), Massenzahl, relative Atommasse, natürliche Isotopenzusammensetzung (Häufigkeit) und die Standard-Atommasse des Elements. Suchen Sie ein Isotop nach Bezeichnung (C-12, U-238) oder nach Symbol + Masse, listen Sie alle Isotope eines Elements auf, ordnen Sie Isotope nach Masse oder natürlicher Häufigkeit oder suchen Sie. Eine präzise physikalische und chemische Referenz für Wissenschaft, Bildung, Labor- und Ingenieuranwendungen. Unterscheidet sich von elementaren Daten.

Hot Air Balloon Lift API
Hot-air-balloon lift maths as an API, computed locally and deterministically — the thermal-lift, envelope-temperature and air-density numbers a balloon pilot, designer or physics teacher works a flight out with. The lift endpoint gives the buoyant lift from heating the air: gross lift = envelope volume × (outside air density − inside air density), the densities from the ideal-gas law — a 2,500 m³ envelope at 100 °C on a 15 °C day lifts about 698 kg gross, from which you subtract the envelope, basket, burner and fuel for the payload, and the hotter the air and colder the day the more it lifts. The required-temp endpoint inverts it: to carry a target lift the inside air must reach a particular density and so a particular temperature, with a check that it stays under the ~120 °C that nylon envelopes can take — the everyday pre-flight question of whether the balloon can lift today's crew and fuel. The air-density endpoint gives the moist-air density ρ = (P − 0.378·Pv) ÷ (R·T), and explains the counter-intuitive fact that humid air is LESS dense than dry air, slightly cutting the lift. Everything is computed locally and deterministically, so it is instant and private. Ideal for ballooning and aviation tools, STEM and physics-education apps, and buoyancy calculators. Pure local computation — no key, no third-party service, instant. Idealised dry-lift model. 3 compute endpoints. For Archimedes flotation in water use a buoyancy API; for party-balloon helium lift a balloon API.

Vacuum Technology API
Vacuum-Technologie-Mathematik als API, lokal und deterministisch berechnet – die Pumpdown-, Siede- und Druckzahlen, mit denen ein Labortechniker, Verfahrensingenieur oder Vakuum-Hobbyist arbeitet. Der Pumpdown-Endpunkt liefert die ideale Zeit zum Evakuieren einer Kammer, t = (Volumen ÷ Pumpgeschwindigkeit) × ln(Start ÷ Zieldruck) – eine 10-Liter-Kammer mit einer 5 L/s-Pumpe fällt theoretisch in etwa 14 Sekunden von 1000 auf 1 mbar, obwohl Ausgasung und fallende Pumpgeschwindigkeit die reale Niederdruckphase verlängern. Der Siedepunkt-Endpunkt liefert die Temperatur, bei der Wasser unter reduziertem Druck siedet, basierend auf der Antoine-Gleichung: etwa 100 °C auf Meereshöhe, aber nur ~52 °C bei 100 mbar und ~46 °C bei 100 mbar – die Physik hinter Vakuumentgasung, Gefriertrocknung und Höhenkochen. Der Level-Endpunkt wandelt einen Druck in die gängigen Vakuumeinheiten (mbar, Torr/mmHg, Pa, kPa, inHg, atm, psi) um, meldet den prozentualen Vakuumgrad relativ zur Atmosphäre und benennt das Regime – Grobvakuum, Feinvakuum, Hochvakuum oder Ultrahochvakuum – damit Sie wissen, welche Pumpe und welches Messgerät die Aufgabe benötigt. Alles wird lokal und deterministisch berechnet, daher ist es sofort und privat. Ideal für Vakuumlabor- und Prozessanwendungen, Pumpenauslegungs- und Entgasungswerkzeuge, Halbleiter- und Beschichtungsrechner sowie Physikunterricht. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Live, nichts gespeichert. 3 Compute-Endpunkte. Ideale Schätzungen – reale Systeme werden durch Ausgasung und Lecks verlangsamt.

Center of Mass API
Centre-of-mass and barycentre mechanics as an API, computed locally and deterministically. The point-masses endpoint computes the centre of mass of a system of point masses in one, two or three dimensions, applying x_com = Σ(m_i·x_i)/Σm_i to each axis from a list of masses and their x (and optional y and z) coordinates — masses of 1, 2 and 3 at positions 0, 1 and 2 give a centre of mass at 1.333, and four equal masses at the corners of a square sit at its centre. The two-body endpoint computes the barycentre of two masses separated by a distance, r1 = d·m2/(m1+m2) from the first body, which always lies closer to the heavier one — for the Earth-Moon system the barycentre is about 4 670 km from Earth’s centre, still inside the planet. Lists may be passed as comma-separated values (masses=1,2,3&x=0,1,2) or as JSON arrays in a POST body, and units are consistent and unit-agnostic. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics, engineering-statics, astronomy, robotics, game-physics and mechanics-education app developers, balance-point and barycentre tools, and simulation software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is the centre of mass; for the rotational moment of inertia use a moment-of-inertia API.
