The speed of sound depends on the phase of the material (solid, liquid, or gas). In general, sound travels fastest in solids, then liquids, then gases.
The atomic theory of Dalton was fatally flawed by his belief that the same atoms couldn’t combine.
Temperature is a measure of the average translational kinetic energy a single molecule in a given system possesses.
“If you want to learn about nature, to appreciate nature, it is necessary to understand the language [of mathematics] that she speaks in. She offers her information only in one form; we are not so unhumble as to demand that she change before we pay any attention.” -Feynman on Why We Need Math
Michael Faraday’s experiments in the 1830s provided an initial “peek” at the electrons inside the atom.
Einstein’s light quanta hypothesis met with tremendous resistance, taking almost twenty years after its introduction in 1905 to be fully accepted. Despite such opposition, Einstein continued to use the concept in his work with significant success.
The atoms of a Bose-Einstein fluid are in the exact same quantum state.
A laser is possible because photons are Bosons and not Fermions.
Aristotle criticized Democritus‘ atomic theory, which both hindered its acceptance and provided the majority of what we know about it.
If the wavelength of visible light was as large as that of a sound wave you’d be able to see around corners.
