Infinite nature Read the answer Urgent, urgent, urgent! ! ! ! ! good bonus points

Infinite Nature ① Nature is both simple and complex, like a simple, kind, yet profound scholar. It hides its profound connotation, but appears extremely easy-going and easy-going on the outside.

②Nature seems to favor simple ways of living. Simple-minded antelopes can also live leisurely in the prairie, and earthworms that never think can also roam freely underground and multiply. Nature only needs to give them a few "instincts" as special skills, which will be enough for them to last a lifetime. If you see earthworms climbing up the raised road surface for no reason, there will be a heavy rain in two days. We humans have used so many advanced technologies: space rockets, weather satellites, space remote sensing and large computers to analyze weather cloud images one after another to make 48-hour weather forecasts, but sometimes the forecasts are inaccurate. And how can this little earthworm, which has a straight line to the end and cannot be simpler, make such an accurate weather forecast? ③ Nature is fair, it favors the simple, but also rewards the complex. It always creates problems for the complex, but never for the simple. Trouble always belongs to those with complex minds. Nature created thinking humans, but it is just playing a never-ending "guessing game with prizes" with it.

④ Human ancestors were full of mystery, fear and confusion about nature out of ignorance. Some of today’s scientific giants are out of a thorough understanding of nature and are also attracted by its incredible beauty, solemnity and profoundness. Shocked. Both types of people have a heartfelt reverence for nature, but only those modern people with "half a bottle" of superficial knowledge feel indifferent. What we face is always an infinite nature. Infinity is surrounding us, and the earth is full of flowers and stars everywhere.

⑤ People have discovered interesting mathematical series (Fibonacci series) centuries ago: 3, 5, 8, 13, 21, 34, 55, 89... This series The biggest features are: (starting from item 3). This series is extremely closely related to natural plants. The number of petals of almost all flowers comes from one number in this series: the square-shaped bracts on the skin of pineapple form two sets of spirals with opposite spirals, and their number must be the two immediately adjacent numbers in this series (such as 8 rows left-handed, 13 rows right-handed); and the sunflower disk...how strange! If the number of lines of the two sets of spirals is exactly the same, wouldn't it be more strictly symmetrical? But nature doesn’t! It was not until recently in 1993 that people gave a truly satisfactory explanation for this ancient and important series: any two adjacent numbers in this series, divided sequentially, have a ratio closest to 0.618034... This value, its limit is the so-called "golden section".

⑥Although what we are most exposed to in daily life are finite, they may be several links in an infinite chain.
