Dissipation is an obvious fact of everyday life. All the energy generated by power plants is eventually dissipated, and contributes to global warming. Thermodynamics tells us that time's arrow points towards increasing entropy. This decay of order occurs at a rate controlled by material properties such as resistivity, viscosity, and diffusivity.

耗散是日常生活中显而易见的事实。发电厂产生的所有能量最终都会被消耗掉，并导致全球变暖。热力学告诉我们，时间的箭头指向熵的增加。这种有序的衰减发生在由材料特性如电阻率、粘度和扩散率控制的速率上。
