Structural / Applied Eng
Primary structural component of an aircraft that generates the lift necessary to overcome the plane's weight.
Wing / Airfoil
This subatomic particle carries a negative charge and flows through conductors to create electrical currents.
Electron
This outermost, highly mineralized layer of the human tooth is the hardest substance in the human body.
Enamel
This fundamental force keeps planets in orbit around the sun and causes objects to fall toward Earth.
Gravity
In calculus, this fundamental tool represents the instantaneous rate of change or the slope of a tangent line.
A derivative
Civil engineers use this triangle-based structural framework to distribute weight across bridges and roofs.
Truss
This type of nuclear reaction involves splitting a heavy atomic nucleus into smaller fragments, releasing massive energy.
(Nuclear) Fission
This specialized type of brain cell uses electrical and chemical signals to transmit information throughout the nervous system.
Neuron
On the pH scale, any value below this specific number indicates an acidic solution.
7
Sound waves are this type of wave, meaning the particles of the medium vibrate parallel to the direction the wave travels.
Longitudinal wave
In mechanical engineering, this term describes the rotational twisting applied to an object (e.g., when turning a crankshaft).
Torque
Chemical engineers measure this property of a fluid to determine its internal resistance to flow.
Viscosity
This boundary surrounding a black hole represents the point of no return, where even light cannot escape its gravity.
The Event Horizon
Newton’s third law of motion states that for every action, there is an equal and opposite one of these.
Reaction
This famous ratio, roughly equal to 1.618, appears frequently in nature, architecture, and classical art layouts.
Golden Ratio
Mach numbers greater than 5.0 are classified by this term, crucial for military pilots and rocket design.
Hypersonic
This fundamental law of chemistry states that mass cannot be created or destroyed in a closed system during a chemical reaction.
Law of Conservation of Mass
This gap between two neurons is where neurotransmitters are released to pass a signal to the next cell.
Synapse
This term refers to a substance that speeds up a chemical reaction without being permanently changed or consumed itself.
A Catalyst
In music theory, doubling the frequency of a sound wave produces a note that is exactly one of these intervals higher.
Octave
Industrial engineers utilize Lean Six Sigma (an industrial methodology) to target "Muda," which is the Japanese word for what unwanted system element?
Waste
Named after a French physicist, this rule states that the total current entering a junction must exactly equal the total current leaving it.
Kirchhoff's Current Law
Standard adult humans typically have this total number of permanent teeth, including the wisdom teeth.
32
Absolute minimum, the theoretical temperature where all molecular motion stops, is equal to this many degrees Kelvin.
0 Kelvin
This branch of calculus is primarily used to find the total area accumulated under a curve.
