Today's hexagram:Fire Thunder Devouring (䷔)

The Book of Changesitemtwenty-oneHexagram: Upward departure (fire) and downward vibration (thunder), thunder and lightning strike, clear and clear obstacles.

Hexagram revelation: The core meaning of this hexagram isThe objective law of "breaking barriers and regulating order" is revealed through "clear and just punishment, and combining hardness and flexibility" - in the process of the development of all things in the world, obstacles, mistakes, and chaos are inevitable, just like there are impurities in the mouth that hinder chewing. Only by decisively biting and removing them can we eat normally; Only by discerning right from wrong with a discerning heart, breaking down obstacles with decisive power, and punishing mistakes with just laws can we straighten out order and clear the way forward. This is not only the natural operating law, but also the core principle of dealing with people and governing the country.

The most outstanding contribution isone thousand eight hundred and eighty-sixFor the first time in the year, highly toxic and highly reactive elemental fluorine was successfully produced through electrolysis, solving a problem that had plagued the chemical industry for decadesHe also inventedMohs electric furnace "is used for preparing various metals and compoundsThe fluorine production method is still an industrial foundation to this day; Electric furnaces have promoted high-temperature chemistry and materials science. His research paved the way for understanding halogen chemistry and exploring extreme conditions for synthesis, and he is revered as one of the founders of modern inorganic chemistry。其制氟方法至今仍是工业基础；电炉则推动了高温化学与材料科学。他的研究为理解卤素化学和探索极端条件合成开辟了道路，他被尊为现代无机化学奠基人之一Mowasan
