Slim + Rigid + Pocket-sized

The card is black-plated stainless steel, 0.7 mm thin. This is enough to feel solid between your fingers, yet slim enough to slide into a wallet or sleeve without adding bulk. It won't bend in a back pocket. It won't snap if you drop it.

Credit-Card Sized: At 87 * 59 mm, it’s the same footprint as a standard credit card. Put this is your wallet, card sleeve, phone case, badge holder, or notebook pocket. Wherever you keep the things you actually use, the card fits.

The card contains roughly 100 formulas across five major areas of physics:

• Mechanics: velocity, acceleration, equations of motion, Newton’s second law, momentum, impulse, work, power, kinetic and potential energy, Hooke’s law, circular motion, torque, rotational motion, moment of inertia, gravity, escape velocity, pendulums, simple harmonic motion, density, pressure, and fluid pressure.
• Thermal Physics: heat flow, sensible and latent heat, molecular kinetic energy and speed, entropy, the laws of thermodynamics, internal energy, ideal gas law, thermal expansion, heat-engine efficiency, refrigeration coefficient of performance, Maxwell–Boltzmann distribution, Wien’s law, thermal conduction, and thermal radiation.
• Waves and Optics: periodic waves, frequency, intensity, sound levels, beat frequency, Doppler effect, Snell’s law, refraction, critical angle, Mach angle, Cherenkov angle, interference fringes, spherical mirrors, magnification, and image location.
• Electricity and Magnetism: Coulomb’s law, electric fields, electric potential, current, resistance, electric power, series and parallel circuits, capacitors, capacitive energy, magnetic forces, motional EMF, solenoids, inductive reactance, and electromagnetic pressure.
• Modern Physics: special relativity, Lorentz factor, time dilation, length contraction, relativistic velocity and Doppler effect, mass–energy equivalence, energy–momentum, photon energy and momentum, the photoelectric effect, atomic spectra, radioactive activity, half-life, absorbed and equivalent radiation doses, and Schrödinger’s equation.

The chemistry card includes formulas across these major topics:

• General Chemistry: concentration, dilution, moles, density, empirical and molecular formulas, and percent composition.
• Stoichiometry and Gas Laws: ideal and real gas equations, Boyle’s, Charles’s, Dalton’s, Graham’s and Henry’s laws.
• Thermodynamics and Kinetics: heat, reaction rates, Gibbs free energy, enthalpy, entropy, activation energy, half-life and Hess’s law.
• Electrochemistry: cell potential, EMF, Nernst equation, Faraday’s law and conductivity.
• Organic and Polymer Chemistry: hydrocarbon formulas, alcohol oxidation, SN1/SN2 reactions, polymerization and molecular weight.
• Atomic, Quantum and Nuclear Chemistry: photon energy, atomic energy levels, Schrödinger equation, radioactive decay and binding energy.
• Solutions and Equilibria: solubility, precipitation, buffers, acid–base equilibria and colligative properties.
• Surface and Phase Chemistry: adsorption, catalysis, surface tension, phase equilibria and statistical thermodynamics.
• Biochemistry and Photochemistry: ATP energy, biological buffers, enzyme kinetics, quantum yield and fluorescence.
• Inorganic, Analytical and Green Chemistry: ligand-field theory, transition metals, chromatography, detection limits, atom economy and E-factor calculations.

This all-in-one formula card includes formulas across these major topics:

• Algebra and Geometry: quadratic equations, slopes, arithmetic and geometric series, distance, midpoint, areas, volumes and the Pythagorean theorem.
• Calculus and Trigonometry: derivatives, integrals, product and quotient rules, laws of sines and cosines, and trigonometric identities.
