" A Brief History of All Things " Reading Essay (3) 2022.10.03
Today, I am still reading "A Brief History of All Things", reading the third part "Dawn of a New Era", Chapter 8 to 11, namely "Einstein's Universe", "The powerful atom ", "Turn the Lead out", "Mark's Boss Quark ", to page 133.
Einstein made his debut, and he proposed the famous mass-energy equation : E=mc², where E in the equation represents energy, m represents mass, and c² represents the square of the speed of light.
The book simply explains the meaning of this equation, "Mass and energy are equivalent. They are two forms of the same thing: energy is the mass released; mass is the energy waiting for release.
Since c² (the square of the speed of light) is a huge number, this equation means that every object contains a huge - truly extremely large - amount of energy." The explanation of
gave me a new understanding of the importance of action. The second half of this equation is the relationship between mass and speed. So can this equation be used to illustrate that as long as a person acts, he can generate huge energy. The faster the action, the greater the energy, the greater the possible results. If he stagnates, there will be no energy. Of course, the premise is that the direction of action must be correct.
" Energy Conservation " will not be closed in a system. In other words, when energy in a system is no longer conserved, it means that the system has been broken and the energy in the system is exchanging with energy outside the system.
The book says, "After we die, our atoms will be separated from each other and look for new places to use - to become a leaf or other human body or a drop of dew. And the atoms themselves will actually live forever."
I have thought before, where can we wait for eighteen years, and it is not the "six paths" that come in line. Reincarnation is simply the "retribution of the present world". Think about it carefully. When a person dies, he puts it into the furnace of the crematorium and smoke begins to emerge from the chimney. Those smoke and dust are composed of the atoms of the deceased. They are sucked into the lungs, hung on trees, merged into the soil, absorbed by plants, etc., and they are now "reincarnation".
However, this is the "reincarnation" at the material level. If the deceased has a spiritual legacy left in the world, it will continue to affect the living, and that is the "eternal life" at the other level. So some people say, "When a person dies, there is nothing left" is completely unreasonable.
Carl Sagan In the book "The Universe", if you dive into the depths of an electron, you will find that it is a universe itself, in which a large number of small particles form the equivalent of local galaxies and smaller structures. They themselves are the next level of universe. If this goes on forever - a process of gradually advancing in, the universe in the universe will never end - the same goes forth.
This reminds me of a passage in Buddhism, "Sakyamuni said that the world is so big that it is infinite; the world is so numerous, just like the number of sands in the Ganges River. Jizi takes Sumeru. There are 84,000 insects in a drop of water, and there are in a grain of dust and in a thousand thousand worlds ." Perhaps, science is constantly proving something...
