TL;DR: This thread is a review of the book Our Mathematical Universe. This thread is a review of Max Tegmark's book Our Mathematical Universe. The thesis of Our Mathematical Universe is that not only does mathematics perfectly describe the universe, the universe is mathematics.. In this...

No. First of all, I am guessing that you mean page 71. Page 72 does not even have the word maps or map on it. Neither page 71 nor page 72 say that the multipole is the size partitions into which the map is broken up. Neither page 71 nor page 72 say that if the map is sliced into two...

@berkeman you are knowledgeable about physics . What is your opinion on this?

Here is some context. This is pages 71 and 72

When you say that the sine waves need to be in phase, do you mean that the sine waves have to have the same wave length with the crest of each sound wave happening at the same time?

I just finished reading Max Tegmark's book Our Mathematical Universe. There is a diagram on page 72 of Our Mathematical Universe that I don't understand. The diagram shows the temperature fluctuation of four different models: 1# the standard model 2# Budget-deficit model 3# An unnamed model...

That is kind of the thesis of the book Our Mathematical Universe.

I am not a physicist or an engineer like you probably are. I am a long distance truck driver. I need you to explain it to me like I am a five year old

@PeterDonis You are good at explaining complex things to a layman. Please help

No. It does not sound familiar. You are probably a physicist or an engineer. My only physics training is an Physics class that I took in high school over a quarter of a century ago. Do electrons travel on those electromagnetic fields?

I don't know what N*2pie equals. And I don't know what the N in N*2Pie stands for. I have no clue why you mentioned N*2Pie. I had never even heard of N*2Pie in my life before you made that post a few minutes ago.

I recently bought a refrigerator for my semi-truck that has no refrigerant. This refrigerator with no refrigerant has a heat sink to cool off the refrigerator. In terms of physics, how does the heat sink remove heat from the refrigerator?

I am reading Max Tegmark's book Our Mathematical Universe. On page 172, Tegmark wrote the following: "Two waves can pass through each other unaffected, like the circular waves in the water tank in Figure 7.6; at any time, their effects simply add together. In some places, we see peaks of the...
