a scientific idea that all particles are tiny vibrating strings, not point-like dots, and these vibrations create different particles and forces
弦理论, 弦的理论
the bending, spreading, and interference of waves as they encounter obstacles or pass through narrow openings, often observed in the behavior of light, sound, or other waves
衍射
a fundamental particle combining to form protons and neutrons, with fractional electric charge and six flavors
夸克
a fundamental particle with half-integer spin, including electrons and their heavier counterparts, as well as neutrinos
轻子, 轻子粒子
a tiny particle made up of even smaller parts called quarks, like protons and neutrons
强子
(physics) the maximum distance a vibrating material, sound wave, etc. such as a pendulum travels from its first position
振幅
tiny particles that make up matter and have a property called spin, like the building blocks of atoms
费米子
a tiny particle with whole-number spin, such as photons or the Higgs boson, often associated with carrying fundamental forces or giving mass to other particles
玻色子
the force that acts on an object moving in a circular path, directed toward the center of the circle or the axis of rotation, preventing the object from moving in a straight line
向心力, 向心作用力
the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave, producing a shift in pitch or color
多普勒效应, 多普勒效应
the energy possessed by an object due to its motion, defined as one-half the mass of the object multiplied by the square of its velocity, expressed by the equation KE = 0.5 * m * v^2
动能, 运动能量
(physics) an invisible substance that makes up most of the universe's mass, detectable only through its gravitational effects
暗物质, 暗质
(physics) matter consisting of elementary particles that are the antiparticles of those of regular matter
反物质
(physics) the property of matter that gives it weight in a gravitational field and is a measure of its inertia
质量, 物理质量
the smallest possible amount of a particular quantity that cannot be divided any further
量子, 最小量
the strength of a moving object determined by multiplying how heavy it is by how fast it is going
动量, 势头
a fundamental particle of light that carries electromagnetic energy and exhibits both particle-like and wave-like properties
光子
the tendency of an object to resist changes in its state of motion, whether at rest or in uniform motion, and to remain in its current state unless acted upon by an external force
惯性
the action or process where a wave, such as light or sound, bounces back from a surface instead of passing through
反射, 映像
a theory stating that the exact position and momentum of a particle cannot be measured precisely at the same time
不确定性原理
the theory that adds the notion of time to that of a three-dimensional space
时空, 时空理论
the process or action of splitting a nucleus into two or more parts resulting in the release of a significant amount of energy
核裂变, 核分裂
referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation
电磁的
(physics) the reaction in which two nuclei join together and produce energy
核聚变, 核融合
