When we talk about numbers, we tend to overlook their hidden cultural and scientific mysteries. Today, let's step into the world of the number 84 and uncover its little-known side.

Since ancient times, the number 84 has always carried a rich symbolic meaning. In traditional Chinese culture, "eighty-four" is often regarded as the number of reincarnation, implying the cycle of life. In Western astrology, this number is believed to transmit cosmic energy and bring about the beauty of harmony. Whether in religious ceremonies or in the layout of buildings, people will always find the figure of 84 quietly existing.

In addition to its deep historical background, 84 also has unique mathematical qualities. As a multiple of a perfect number, it can be divided into several smaller values, such as 1 × 84, 2 × 42, and so on. Not only that, in the process of geometric figure construction, we can often see the perfect pattern composed of triangles with the right proportion of side length-all these show the concept of nature's unremitting pursuit of balanced aesthetics.

After entering daily life, we will be surprised to realize that there are traces of this unknown friend everywhere. For example, the familiar bottled drinking water is usually engraved on the bottom of the production date plus "+84 days" shelf life mark; similarly, in the marathon scene can be seen many contestants chose to carry the lucky number plate '84 'to the finish line to complete the mission of self-challenge ...... Such phenomena remind us to learn to observe the extraordinary wisdom behind ordinary things.

Of course, there are more wonderful interpretation of cross-border waiting to discover. At the end of the movie "Matrix" trilogy, the main character Neo skillfully borrowed the moment when he defeated the machine army, the continuous scrolling data stream fragment flashed on the screen, which contained countless repeated string sequences: "100%", which is the magic number we are familiar with when converted into decimal! In addition, an open source program hatched within Google, officially named Dart Language v1.84, also attracted widespread attention when it was released.

To test the new knowledge you just learned, please try to answer these small questions:

· Why is the number 84 called the number of reincarnation?
· In which sports events do athletes often see wearing uniforms marked with the serial number 84?
· Which well-known films have implicitly or explicitly used this theme element?

Finally, let's think about the possibility of the future: suppose one day we will give the number 84 a new definition, perhaps as a bridge between virtual reality and the real world, or as an important indicator of human happiness index. No matter how it changes and develops, I believe this once familiar but unfamiliar name will continue to accompany us through the long journey.
