Contrary to the opinion prevalent at that time, de Donder, the founder of the Brussels School of Thermodynamics, considered that thermodynamics should not be limited to equilibrium situations. He created an active school in Belgium. However, his approach remained isolated.

做数学（力学）也需要品位与嗅觉：前者指引我们去研究好的数学（力学），后者体现着研究过程中的直觉与洞察力。

Thermodynamics is a physical theory at once beautiful and useful: beautiful because its laws are simply expressed and deductions from them universally applicable, and useful because in distinguishing the possible from the impossible thermodynamics saves us from much fruitless effort. For these reasons, as well as for its undeniable empirical success, thermodynamics deeply impresses those who grasp its essentials. Albert Einstein once boldly claimed that thermodynamics, alone among physical theories, “will never be overthrown”.


Some main branches of thermodynamics


Learning can be regarded as a helical process, whereby each turn elevates us to the next storey of a building with an infinite number of floors. On each floor the same ideas dwell as on all others, but the perspective is wider. The speed of ascent is strongly dependent on the natural abilities and background of the visitor. Ideally, a good book should help to accelerate this process, regardless of the particular floor of departure.

东北大学校歌 链接

白山兮高高，黑水兮滔滔；
有此山川之伟大，故生民质朴而雄豪。
地所产者丰且美，俗所习者勤与劳。
愿以此为基础，应世界进化之洪潮。
沐春风时雨之德化，仰光天化日之昭昭。
惟知行合一方为贵，惟自强不息方登高。
爱校、爱乡、爱国、爱人类。
期终达于世界大同之目标。
啊 使命如此其重大，能不奋勉乎吾曹？
能不奋勉乎吾曹？
