Physica: Scientific Calculator

Master Advanced Physics and Mathematics with Physica

Physica is a high-performance scientific calculator engineered specifically for physicists, engineers, mathematicians, and STEM students. Moving far beyond basic arithmetic, Physica provides an advanced computational system designed to handle complex expressions, elementary and special functions of a complex argument, and physics constants locally on your device.

Special Functions [Pro]
Forget bulky PC software. Physica Pro includes a dedicated computational core for special functions:
• Advanced Calculus & Probability: Gamma, Beta, and Error functions.
• Wave Mechanics & Electrodynamics: Bessel functions of the 1st and 2nd kind.
• Quantum Mechanics: Associated Legendre Polynomials and Spherical Harmonics.
• Integral Functions: Sine Integral, Cosine Integral, and Exponential Integral.

Physics Constants (SI & CGS)
A built-in database of fundamental constants eliminates the need for reference tables:
• Mechanics: Speed of light, gravitational constant, and standard gravitational acceleration.
• Thermodynamics: Avogadro’s number, Boltzmann constant, universal gas constant, Stefan-Boltzmann constant, and standard atmospheric pressure.
• Electrodynamics: Elementary charge, electron volt, Coulomb's constant, vacuum permittivity, vacuum permeability, and impedance of free space.
• Atomic & Nuclear Physics: Planck constants, fine-structure constant, Bohr radius, atomic mass unit, Bohr magneton, Rydberg constant, and electron, proton and neutron masses.

Elementary Functions
Full support for elementary functions:
• Trigonometry: sin, cos, tan, cot, sec, csc, arcsin, arccos, arctan, arccot, arcsec, and arccsc.
• Hyperbolic Engine: sinh, cosh, tanh, coth, arsinh, arcosh, artanh, and arcoth.
• Logarithms: ln, lg, and log.
• Roots: Square and cube roots.

History & Workspace
• History Log: Track your computations in a structured list (Free version shows your 4 most recent expressions; upgrade to Pro for unlimited history).
• Contextual Actions: Tap any history entry to open quick actions. "Take result" or "Take expression" pulls your past work straight into your live input line.
• Comments: Add custom text comments directly to individual history steps to organize multi-stage engineering computations or lab notes.

Engineering Controls
• Unit Systems: Instantly switch between SI and CGS (Gaussian) systems (only SI in the Free version).
• Answer Formats: View results in standard Algebraic format or switch to Exponential format depending on your scientific constraints.
• Flexible Precision: Choose floating-point display precision up to 14 significant digits (up to 8 digits in the Free version).
• Themes: System-adaptive Light and Dark themes for comfortable work.

Whether you're running a quick check like sin(30°), tackling your physics homework, or working on an engineering project, Physica gives you the exact precision and layout you need to breeze through your work.
