@zhigangsuo I happened to be discussing the concepts of temperature vs vapor pressure with students in fluid mechanics course, trying to extend the discussion to phase diagrams.
Guangji Bridge, a floating boat in the middle connects stone bridges at both ends.
This is a thousand-year-old bridge located in the Chaoshan region in southeastern China.
Before the advent of quantum mechanics, classical physics predicted that black bodies (perfect absorbers of radiation) should emit radiation with infinite energy at ultraviolet and shorter wavelengths, a prediction clearly at odds with physical reality. This problem, known as the ultraviolet catastrophe, was resolved by Max Planck in 1900, who introduced the idea that energy is quantized, laying the foundation for quantum mechanics.

Tillage, texture, or crop diversity – which factor most influences soil microbial abundance and diversity? A recent #SSSAJ on-farm study conducted by Agyei et al. revealed that tillage significantly affects the soil's microbial community https://t.co/180FY20sTj

Thermodynamics is a funny subject. The first time you go through it, you don't understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don't understand it, but by that time you are so used to it, it doesn't bother you any more.

The concept of chemical potential was introduced in 1878 by Gibbs.
Is chemical potential the earliest significant scientific concept made in America? @curiouswavefn

Energy transfers from a place of high temperature to a place of low temperature.
A species of molecules transfers from a place of high chemical potential to a place of low chemical potential.
The analogy plays out in this chapter.
