Statistical mechanics concerns the transition from the microscopic to the macroscopic realm. On a macroscopic scale new phenomena arise that have no counterpart in the microscopic world. For example, macroscopic systems have a temperature; they might undergo phase transitions; and their dynamics may involve dissipation. How can such phenomena be explained? This chapter discusses the characteristic differences between the microscopic and macroscopic realms and lays out the basic challenge of statistical mechanics. It suggests how, in principle, this challenge can be tackled with the help of conservation laws and statistics. The chapter reviews some basic notions of classical probability theory. In particular, it discusses the law of large numbers and illustrates how, despite the indeterminacy of individual events, statistics can make highly accurate predictions about totals and averages.

The space‐time is empirically perceived as a pre-existing property of the universe. However, a special kind of perception that takes place in near-death-experiences (NDEs) is challenging this idea. Here, I will illustrate how understanding of this particular state of consciousness (named the bodiless consciousness) helps us re-think the space‐time structure of the physical world. I first speculate that the bodiless consciousness perceives the physical world as nonlocal 4D. I then propose that the space‐time is a “derived” feature subsequent to the emergence of perception of the bodiless consciousness, rather than a pre-existing and unchangeable property. Next, I explain that the space structure only takes place in the classical (or macroscopic) world rather than in the quantum (or microscopic) world, due to its intrinsic imperceptibility to the bodiless consciousness. Without a presupposed structure of the space, the strangeness of the quantum world is expected. Then, I bring up the old measurement problem. I will argue that it is the bodiless consciousness that may entangle with the superposed state of an observed system and trigger the collapse. Finally, I will briefly discuss the potential relationship between electromagnetic wave and consciousness.
