Memory leak


I have a friend who is a writer. But he only sold 20 books so far, he is  unsuccessful as Kilgore Trout, but he is not at all famous like Kilgore Trout. I got a permission from him to write his plot here. Otherwise, nobody knows him at all. The title of the story is ``Memory leak''.
The main character ``Fred'' in the story is a researcher of ``resurrection''.  It is called ``resurrection'' in general, but he found that is more like a sharing memory with past people. Fred found there are resurrected people who has more than two people's memory. Though many of the case, the contents of the memory is corrupted.
Fred realized he shared his memory with his young six-year-old daughter. The memory share is not necessary with a past person. One day, he lost his wife and his daughter by a space travel accident. He shared a piece of memory with his daughter's last moment. That is physically nonsense, maybe not true. But, he has a hypothesis of this phenomenon: this world is not a physical world. This world is a simulation. There is some kind of bug in the simulation, that is observed as a memory leak. He was in sorrow. Other people think he become crazy. But he try to exploit this bug and try to get back his wife and his daughter. 
There are many SF about a virtual world, including how the magic works and how a time machine works, but in his story, resurrection is cased by a simulation bug. I found it interesting.

Why A^{T}A is invertible? (2) Linear Algebra

Why A^{T}A has the inverse Let me explain why A^{T}A has the inverse, if the columns of A are independent. First, if a matrix is n by n, and all the columns are independent, then this is a square full rank matrix. Therefore, there is the inverse. So, the problem is when A is a m by n, rectangle matrix.  Strang's explanation is based on null space. Null space and column space are the fundamental of the linear algebra. This explanation is simple and clear. However, when I was a University student, I did not recall the explanation of the null space in my linear algebra class. Maybe I was careless. I regret that... Explanation based on null space This explanation is based on Strang's book. Column space and null space are the main characters. Let's start with this explanation. Assume  x  where x is in the null space of A .  The matrices ( A^{T} A ) and A share the null space as the following: This means, if x is in the null space of A , x is also in the null spa

Gauss's quote for positive, negative, and imaginary number

Recently I watched the following great videos about imaginary numbers by Welch Labs. https://youtu.be/T647CGsuOVU?list=PLiaHhY2iBX9g6KIvZ_703G3KJXapKkNaF I like this article about naming of math by Kalid Azad. https://betterexplained.com/articles/learning-tip-idea-name/ Both articles mentioned about Gauss, who suggested to use other names of positive, negative, and imaginary numbers. Gauss wrote these names are wrong and that is one of the reason people didn't get why negative times negative is positive, or, pure positive imaginary times pure positive imaginary is negative real number. I made a few videos about explaining why -1 * -1 = +1, too. Explanation: why -1 * -1 = +1 by pattern https://youtu.be/uD7JRdAzKP8 Explanation: why -1 * -1 = +1 by climbing a mountain https://youtu.be/uD7JRdAzKP8 But actually Gauss's insight is much powerful. The original is in the Gauß, Werke, Bd. 2, S. 178 . Hätte man +1, -1, √-1) nicht positiv, negative, imaginäre (oder gar um

Why parallelogram area is |ad-bc|?

Here is my question. The area of parallelogram is the difference of these two rectangles (red rectangle - blue rectangle). This is not intuitive for me. If you also think it is not so intuitive, you might interested in my slides. I try to explain this for hight school students. Slides:  A bit intuitive (for me) explanation of area of parallelogram  (to my site, external link) .
