How do scientists memorize complex physical formulas?

Scientists are talents in a certain field. They only need to memorize the formulas involved in research in this field. There are not many formulas in a field. A scientist will always remember them after using them intentionally or unintentionally for several years or decades. This is not difficult.

Take computational fluid dynamics as an example. For those working in this direction, it is very simple to remember these formulas. Some scientists remember this even better than how much money they have in their homes. For laymen, it's more difficult, it's like a heavenly book.

Three major conservation formulas:

This is a very good question. Memorizing physical formulas is the basis for learning physics well, and it is also the key to improving the ability to learn physics in the future. Remember the formulas well and learn physics well. The chances are high. If you can’t remember the formulas, you will definitely not learn physics well. Of course, we don’t need scientists to memorize physics formulas. Many of the scientists’ memory methods are non-replicable. Today, Sir Yi Xue will share them with you. How to memorize physical formulas

First: "Putting pen" A good mind is not as good as a bad pen

Memorizing is a relatively boring process. Sir Yi Xue first recommends that you put pen to paper. As the saying goes, "Good writing" "A brain is not as good as a bad pen." The process of writing with a pen is an output process. This process requires the use of the brain, which avoids problems such as mind wandering, and improves concentration, which is very beneficial to our memory

Part 2 2: The choice of "time" is very important

It is very important to choose the time to memorize formulas. If you choose the right time, you will get twice the result with half the effort. It is recommended to choose a time with high learning efficiency, such as getting up early. If you choose noon, the boring formula will be very boring. It may make you take a lunch break, and the effect of recording formulas in a good time period will definitely be great;

Third: "State" tells yourself that I can do it

Don't treat memorizing formulas as a kind of To complete the task, only seek the process and not the result. Before announcing the memory, you must tell yourself: I can do it. Many students will forget this. When you have a correct psychological hint, your memory effect will be twice the result with half the effort;

Fourth: "Thinking" Learning without thinking is useless

Memorizing by rote will only make you blindly memorize, and the effect will not be very good. Think while memorizing, don't just After seeing the outside of the formula, you need to see the inside of the formula and understand why there is this formula. The deeper the understanding, the better it will be for memory. If you add some extensions and associations, the memory effect will be better;

Fifth: "Apply" if you don't use it, you will forget it

When you memorize this formula and don't use it for a long time, you will slowly forget the formula. I believe many people have this Experience, so after memorizing it, you must learn how to use the company and how to solve problems. In the process of using it, your memory of the formula will be more profound. Even if a long time passes, the formula will still be deeply ingrained in your mind;

Sixth: "Review" repetition develops a habit

Many formulas are memorized quickly and forgotten even faster, so necessary review must be done, such as memorizing them on the first day. The company, review on the second day, the fourth day, the seventh day... and so on, it is impossible to forget the company. In this way, memorizing the company will develop a habit over time, and the memory speed and memory time will be very good later. improvement.

That’s all Yi Xue sir’s sharing about physical formulas today. I hope it can help you.

Let me talk about my experience. I work in space physics and there are many formulas, especially in plasma. There are many formulas, ranging from simple to complex.

Relatively simple basic equation describing magnetic fluid:

But please note that this equation is nonlinear, and its expression will explode after several orders of linear perturbation expansion

What is more complicated is the expression of the fluctuation growth rate:

These can be used in daily scientific research.

However, there is no need to memorize the complete symbol without missing it. It is OK to know that there is such a formula and the physical images corresponding to the symbols in the formula.

These formulas have been applied many times and have very mature solutions. When we need to calculate something, we can just quote the previous code directly.

There are two aspects.

First, since he is a scientist, his IQ and memory are definitely much stronger than ordinary people. Just imagine, how much knowledge do you need to learn to become a scientist? According to the current academic system, at least in addition to the regular 12-year education, one needs to complete undergraduate, master's and doctoral degrees, and scientists are only just outside the door.

Even two to three hundred years ago, one had to learn a lot of basic knowledge before becoming a scientist. So, how much do you need to remember in these ten years of study? How many formulas do you remember? How can you be a scientist without a good memory?

Secondly, no matter how complicated the formula is, as a person in this profession, he is still a cutting-edge scientist. For him, these formulas need to be frequently exposed, and even the entire derivation process is extremely familiar. Since we are exposed to it day after day, no matter how complicated the formula is, we will still be very familiar with it.

Just like any profession, if you have been engaged in a job for a long time, no matter how complicated the process is, it will become easy for you. You don’t need to think about it specifically, it has become a habit.

Therefore, no matter how complicated the formula is, as long as it is in one's own professional field, it is not a problem for a scientist to remember it. Asking such a question is obviously looking at the matter from an outsider's perspective. It's like when we see an excellent player controlling the ball very accurately, some people may ask how he does it.

Telling three stories can explain everything very well.

The great Euler in the 18th century was a genius recognized by the world. In the age before computers, the search for Mersenne primes was quite difficult. In 1588, Italian mathematician Cataldi (1548-1626) found the sixth and seventh Mersenne primes, M17 and M19, but there was no search for them for more than two hundred years. Until 1772, when Euler was blind, he obtained the eighth Mersenne prime number M31 by relying only on mental arithmetic, which was the largest known prime number in the world at that time.

Euler unfortunately lost sight in one eye when he was 28 years old. Thirty years later, he also lost sight in the other eye. Even after he lost his sight, he never stopped studying mathematics. He continued to work with amazing perseverance and perseverance. During the seventeen years between his blindness and his death, he also dictated several books and about 400 papers.

my country’s great mathematician, Chen Jingrun. Behind the genius is a pair of hands, a pen and countless scratch papers. His calculations are all in sacks. We can even say that Chen Jingrun’s achievements in mathematics were obtained by overdrafting his life.

The 21st century is an era of technology and information explosion. Each subject does not exist alone. The amount of calculations behind it are billions of times, which requires supercomputers to calculate.

To learn physics well, you still need to find more methods and more rules. There is no one memory method that can help you remember everything.

Physical formulas are not all memorized.

Since physical formulas are reasonable and proven formulas, they have meanings. Although some formulas are complex, smelly and long, when scientists grasp the meaning or principle they express, , it can be deduced directly, and there is no need to memorize it at all.

In addition, if you forget a very popular formula, if you want to use it, can't you look up the information? Why should we remember it? I remember reading an article that said that during a meeting, Einstein forgot a certain formula and looked through the books.

Have a question?

I would like to share my rough opinion on whether I can remember some complex physical formulas:

The first one comes from interest. As long as you are interested, you will definitely be familiar with some concepts and formulas. , the ins and outs of the theorem, and I am familiar with it. If I have a deep understanding of it, how can I not remember it?

The second one comes from perseverance. In the process of growing up as a scientist, you must have paid a lot. Some things may be forgotten after a long time. Remember them more. Every subject has rote memorization. Spend more time on memorizing knowledge points, right?

The third rule comes from self-confidence and belief that you are the best. You can understand and remember no matter how complicated the formula is!

I wish the students success in their studies.

It's not difficult.

1. Since it is a formula, the regularity is very strong.

2. Long-term contact, small-scale contact, and familiarity.

It is not like your exam, where you memorize many subjects, the time is very short, you understand less and memorize more, and it is easy to forget.

Scientists study a fixed field. They go to work and get off work every day, and they keep these formulas over and over again. They keep experimenting and revising, and they still keep these formulas. Very familiar.

3. The shop owner has so many things that he can remember the price of each one. I have become familiar with it every day.

4. When I was in middle school, I discovered a mathematical formula. It was relatively simple at the time, but as the grades increased, this formula became more and more complex. A stranger would be in a state of confusion if he took one look at it, let alone remember it.

But I remember it accurately, and I won’t be wrong, because each symbol was derived after a long period of time. I know the origin process of each symbol. It is impossible to think wrong. .
