From the Book: A molecular storm is a term used to describe the constant and random motion of molecules and atoms at the nanoscale. This motion is caused by the thermal energy of the system, and it is responsible for many of the fundamental processes of life, such as diffusion, chemical reactions, and protein folding. Molecular storms are also thought to play a role in the formation of complex structures such as crystals and living cells. For example, when molecules collide with each other in a random fashion, they can sometimes form ordered structures by chance. This process is known as self-assembly, and it is thought to be re- sponsible for the formation of many of the complex structures we see in the natural world. In addition to their role in the formation of complex structures, molecular storms also play a role in the destruction of existing structures. For example, molecular storms can cause proteins to unfold and DNA to break apart. This can lead to cell death and other problems. Overall, molecular storms are a fundamental part of the nanoscale world. They are responsible for many of the processes that are essential for life, but they can also be destructive.
