Appendix: Where Do These Constants Come From?
In science and engineering, the accuracy of our calculations depends entirely on the quality of our input. A physical constant, like the charge of an electron or the speed of light, isn’t just a number—it’s a fundamental piece of the universe’s blueprint, measured and refined through decades of rigorous experimentation. But where do the officially recognized values come from?
The values used in the PhysiConstant app are sourced from internationally recognized standards organizations that compile and critically evaluate data from thousands of experiments worldwide. These are the primary sources professionals rely on:
- CODATA (Committee on Data for Science and Technology): This is the gold standard. CODATA periodically provides the internationally accepted set of values for fundamental physical constants. Their recommendations are based on a least-squares adjustment of all available experimental data.
- NIST (National Institute of Standards and Technology): A US-based organization, NIST is a leading authority on physical measurement. Their databases are a primary source for a vast range of constants and material properties, and their work is a major input to the CODATA recommendations.
- IUPAC (International Union of Pure and Applied Chemistry): For constants and data specifically related to chemistry, such as atomic weights and physicochemical properties, IUPAC is the definitive source.
By drawing from these authorities, we ensure that every constant in the app is reliable, up-to-date, and ready for any calculation you can throw at it.
An Overview of the Constant Categories
The app organizes hundreds of constants into logical categories to make them easy to find and explore. Here’s a brief summary of what you’ll find in each one.
Electromagnetism 💡 This field of physics studies the electromagnetic force, which includes the interactions between electrically charged particles. It covers concepts like electric fields, magnetic fields, electricity, and light.
Atomic & Nuclear ⚛️ This area focuses on the physics of the atom and its nucleus. Atomic physics studies the atom’s structure and electron shells, while nuclear physics deals with the composition and behavior of the atomic nucleus, including radioactivity and nuclear reactions like fission and fusion.
Thermodynamics 🔥 Thermodynamics is the study of the relationships between heat, work, temperature, and energy. It deals with the transfer of energy from one place to another and from one form to another, governed by the laws of thermodynamics.
Physicochemical 🧪 This term relates to physical chemistry, a discipline that applies the principles and techniques of physics to study chemical systems. It explores topics like chemical kinetics, thermodynamics, and quantum mechanics at a molecular level.
Material Properties 🧱 This refers to the intensive and extensive properties of materials. It describes how a material behaves under different conditions, including its mechanical, thermal, electrical, and optical characteristics (e.g., strength, conductivity, hardness).
Semiconductors 🔌 Semiconductors are materials with electrical conductivity between that of a conductor (like copper) and an insulator (like glass). They are the foundational materials for modern electronics, used in transistors, diodes, and integrated circuits.
Fluid Mechanics 💧 This is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. It can be divided into fluid statics (the study of fluids at rest) and fluid dynamics (the study of fluids in motion).
Acoustics 🔊 Acoustics is the science that deals with the study of all mechanical waves in gases, liquids, and solids, including topics such as vibration, sound, ultrasound, and infrasound. It covers the production, control, transmission, and reception of sound.
Astrophysical 🔭 This relates to astrophysics, which is a branch of space science that applies the laws of physics and chemistry to understand the universe and celestial objects like stars, planets, and galaxies.
Geotechnical 🌍 This pertains to geotechnical engineering, which is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses principles of soil mechanics and rock mechanics to investigate subsurface conditions.
Optics & Photonics 👁️ Optics is the branch of physics that studies the behavior and properties of light. Photonics is the science and technology of generating, controlling, and detecting photons, which are particles of light. Together, they cover everything from lenses and mirrors to lasers and fiber optics.
Nuclear Engineering ☢️ This is an engineering field that deals with the application of breaking down atomic nuclei (fission) or combining them (fusion). It includes the design, construction, and operation of nuclear power plants, as well as applications in medicine (medical imaging) and industry.
Dimensionless Numbers 🔢 These are numbers without any physical units. They are pure numbers that are often ratios of two quantities with the same units. They are widely used in engineering and physics (especially fluid mechanics and heat transfer) to simplify problems and compare the importance of different physical phenomena (e.g., the Reynolds number).
