“螺旋是什么?”我晕!作为数学达人,你不会连螺旋都不认识吧?螺旋是自然界中常见的曲线,天上地下到处都有。走,一起见识见识去!把一枚鹦鹉螺的外壳剖开,你就会看到一条近乎完美的螺旋线,数学家们管这叫黄金螺线。当然,如果你是一枚鹦鹉螺的话,最好还是躲着点儿数学家们吧! “What is a spiral? ” I faint! As a mathematical person, you do not even know the spiral? Spiral is a common curve in nature, everywhere in the sky. Go, together to see the knowledge! Split a nautilus shell, you will see a nearly perfect spiral, mathematicians who call the golden spiral. Of course, if you are a nautilus, it is best to avoid some mathematicians!
