A few days ago, I was quite busy. I didn’t get enough sleep every day, so I always catch up on the plane. Whether it’s a flight of more than an hour or a flight of two or three hours, when I get on the plane, I stick to my chair. Strangely, I dream every time. Different from the dream on the ground, the dream on the plane is even more bizarre. After waking up from the dream, one often feels melancholy, unable to figure out whether it is in the sky or on the ground. He is in a trance and in a fog. Sometimes when I open my eyes and find that the plane is still flying, I feel that the flight itself seems to be in my dream. I can’t figure out where I am. There is no boundary outside my dream. It feels very strange.
Speaking, what impressed me most was such a dream: one day, in a sunny place, I met elon musk. He said he would send 1 million people to Mars. I was a little unconvinced and felt that his idea was a little bit off, so I asked a question: ” how much is a million people? Suppose a person weighs 100 kg, then one million people weigh 50,000 tons. The current rocket has a maximum load of 60 tons. It takes 6 to 8 months for the rocket to fly from Earth to Mars. The current technology is not able to return successfully every time. Apart from the huge cost, it is a huge problem to only say how to transport the 50,000 tons of living creatures and the food and excrement that people eat, drink and scatter to Mars in 6 to 8 months. Therefore, according to the current load and speed of these rockets, it is unreliable to send 1 million people to Mars. 」
Since ancient times, people have believed that besides the body, there is still a soul. In modern society, some people also call the soul consciousness. However, whether consciousness or soul exists or not has always been a mystery. So from a scientific point of view, does the soul exist? First of all, we must admit that from a scientific point of view, the soul must not exist. For what can be linked to science must be proved or falsified, and the existence of the soul cannot be proved or falsified. To say that the soul exists, we do not have any evidence. To say that the soul does not exist, we also cannot produce any evidence. Most of the so-called evidences in the hearsay are untenable.
Of all the so-called evidences, the soul has a mass of 21.3 grams, which is the most widely circulated one. But in fact, this really cannot be called evidence, because there were only six experimental samples at that time, and two of them died before the experiment began. You know, the data of the four samples is almost meaningless to analyze the existence of souls, so we don’t need to struggle with whether the four samples have really decreased by 21.3 grams. Even if they are true, they can’t explain anything, unless the samples are not four but 40,000. Other rumors of capturing souls with electromagnetic waves or dyes are even more sensational. If you have to find evidence of the existence of souls, near-death experience is one of them.
The sustainability of a species depends on the reproduction and evolution from generation to generation. Through continuous reproduction and evolution, the species will acquire better ability to adapt to the environment and thus acquire stronger viability. Therefore, the faster the reproduction speed of the species, the more likely it is to survive the cruel environmental changes, because the faster the reproduction speed, the faster the evolution speed. When it comes to reproduction, different organisms have different reproduction characteristics. Some organisms can adopt asexual reproduction, while others must rely on sexual reproduction. While some living organisms are hermaphrodite, while others are hermaphrodite, we human beings are obviously a kind of hermaphrodite sexual reproductive organisms, however, this feature may change in the future.
We all know that the reason why human beings have sex is because there are X and Y chromosomes in our chromosomes. When X and X meet, a little princess begins to conceive. When an X meets a Y chromosome, a little prince sets foot on the course of life. It can be said that the existence of Y chromosome is the key for human beings to have sex. However, scientists have found that in the long process of human evolution, the Y chromosome has been changing. What changes are taking place? The Y chromosome has been getting smaller all the time. Scientists have found that the change of the Y chromosome is not only above the size. In fact, since ancient times, more than 95% of the genes on the Y chromosome have been lost.
Mathematics is the most rigorous science, and mathematics is also the most interesting science. At the age when we just entered the world of mathematics, we were confused by mathematics. At the same time, we were deeply attracted by the charm of mathematics. For most of us, the first interesting problem we came into contact with was the pi, the pi, which is the ratio of the circumference to the diameter. The interesting thing about this ratio is that it is irrational, infinite and does not cycle. In the initial contact with pi, it is very difficult to understand logically. why is there such a number, infinite and not cyclic? In the end, many people silently gave an answer in their hearts, definitely because of their limited calculation ability, they failed to calculate the pi.
In my investment study, my favorite investors are Buffett, Lynch and Max, etc. I will also concentrate on and carefully read, practice and reflect on their books. Buffett’s books are large and small at home, and have been repeatedly read and practiced. Why do I always have the patience and confidence to hold my own portfolio, and most of them also come from the ideas and concepts of ” value investment”.
Today, I would like to share with you Buffett’s eight helpful investment guides.
