What do I think when I'm twenty?

April 6, 1987 was sunny

I'm twenty years old. When I was born, the national calendar was also on April 6. Now, as I was twenty years ago, I'm as ruthless as I was then. At that time, my only instinct was to cry. Now, my parents are not around, and my barrier-based instinct is silent, instinctively living, and the morning is a muddy day.

I woke up early in bed, wondering if I would study physics and write this book "Social Physics". At the same time, however, it is necessary to figure out in great detail the various objective and physical social structures, which cannot be done in a few years.

For example, what kind of social organism can play the role of amplification like a crystal transistor, the rectification effect of a diode, the role of thermal sensitivity and photosensitivity of semiconductors after doping, the effect of dry emission and diffraction of wave simulation, the role of inductive coupling, the role of capacitors, the role of inductance coils, and so on.

It may seem impossible to accomplish this, but there must be a clever way to do it, and this clever way is to borrow physical angles and geometry and analytic ......

My friends neglected their thinking a little and asked them to judge whether the sound waves were transverse or longitudinal, and after a long time, the answer was obvious, but they were silent but could not use their brains, and the result was only guessing. Unfortunately, they were all wrong. Another very simple question, there are four trees at the four corners of a square pond, and now the surface area of the square pond needs to be doubled, and the shape of the square is kept without moving the four trees, how can it be expanded?

After asking this question for a few seconds, I had the right method, and I also inspired the four students in the same class for a long time, telling them that there are only two kinds of changes in the plane direction of objects, translation and rotation (center fixed type), and I still can't understand it, but I can't understand it, but what?

Pay attention to color phenomena: monochromatic light, polychromatic light, dispersion of light, spectrum. According to the wave theory of light, the color of light is determined by the frequency of light, and the higher the frequency, the greater the tearing rate in the medium. Yang's real yàn, like the colorful dry shooting stripes seen on the screen. Presumably, color is not all determined by wavelength, right? So there seems to be something else besides wavelength, right?

In the early stage of teaching, whether it is possible to do not require preview, or even not to preview, is it convenient for heuristic teaching and excessive self-learning.

Under strict rules, ingenious things will be born. Taking Chinese classical poetry as an example, it can be best proved, and their moments can also break through one or two as a last resort, in this regard, the classical poetry art of China is perfect, highly artistic, and highly intelligent. "Autumn Thoughts", "Three Kingdoms Zhou Lang Chibi", "How Many Heroes at a Time", "Beacon Yangzhou Road", "Under the Baboon Shrine, a Crow Shrine Drum", "Blue Sea, Blue Sky and Night Heart"...... Only the name of the sentence, lyrical, musical, and textual effects are achieved at the same time.

Many of the witty lines in the new poems now come from the same thinking but are slightly changed: 'The desolate huqin lengthens the dusk...'' 'That pair of arrogant boots still fall to this day, but the man is gone...... ''At the other end of the border, death, huddled in a gloomy tunnel, aimed at my dream, a crisp sound, splitting me, cultivating sugar cane', is very enlightening.

The rules of composing lyrics, music and poems in ancient times were set by themselves, and they were consciously followed, and there was no compulsion [to be examined]. Many words use their own spectrum, and some of those scores become new genealogies, which are filled in by future generations.

People are flawed, and the rules are even more flawed.

If you need to analyze and compare, then analyze "Jinggu Beiguting Nostalgia".

"This doctor is so pitiful, it's ridiculous! If you buy a TV set, you have to ask someone to take care of it, and when he faces thousands of problems in life, does he rely on thousands of people to arrange them for him?" (Zou Yuezhao's novella "The Bitter Wine at the Banquet"). "The Bitter Wine at the Banquet" reminds me of the cremated "Young Friends". It's a rare novel that writes what I want to say, so I paid for this old book.

My father gave me 5 yuan, and my mother gave me 2 yuan for my birthday, and we couldn't eat better today than before, so I still have a few dimes. Childlike gambling.

In the afternoon, I received the first material from the "Correspondence University of Contemporary Literature in China", which had been announced to be closed last month, but I really didn't understand what was going on, and it was sent on March 31, after the announcement in the newspaper. My student number is 2259, which is already over the expected 1500 students.
