The motive power of heat is independent of the agents employed to realize it; its quantity is fixed solely by the temperatures of the bodies between which is effected, finally, the transfer of caloric.

尼古拉·卡诺

提出卡诺定理，奠定热力学第二定律基础

Wherever there exists a difference of temperature, motive power can be produced.

尼古拉·卡诺

提出卡诺定理，奠定热力学第二定律基础

The production of motion in steam-engines is always accompanied by a circumstance on which we should fix our attention. This circumstance is the re-establishing of equilibrium in the caloric.

尼古拉·卡诺

提出卡诺定理，奠定热力学第二定律基础

In the fall of caloric, motive power evidently increases with the difference of temperature between the warm and cold bodies.

尼古拉·卡诺

提出卡诺定理，奠定热力学第二定律基础

The maximum of motive power resulting from the employment of steam is also the maximum of motive power realizable by any means whatever.

The general struggle for existence of animate beings is not a struggle for raw materials nor for energy which exists in plenty in the form of heat, unfortunately untransformably, in every body; it is a struggle for entropy, which becomes available through the transition of energy from the hot sun to the cold earth.

路德维希·玻尔兹曼

The general struggle for existence of animate beings is not a struggle for raw materials—these are for organisms in ample supply—nor for energy which exists in plenty in any body in the form of heat, but a struggle for entropy, which becomes available through the transition of energy from the hot sun to the cold earth.

The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can’t be measured or give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can’t be measured easily isn’t very important. This is blindness. The fourth step is to say that what can’t be easily measured really doesn’t exist. This is suicide.
