In the last article《科普:浪漫的数学、有趣的物理,科学世界里的一对情侣》, Lao Guo talked with his friends about the romance and physical fun of mathematics. At the end of the article, I said that the following article should give a few examples. However, due to the level of Lao Guo, I wrote a 10,000-word manuscript yesterday. I always feel that there is a lack of romance and the level of interest is not enough. Just right, there is a small partner who personally believes me and asks: "Is it difficult to be a mathematics or a physics?" I used a conversation between the mathematician and the physical handsome first date to talk to the little friends about this topic, by the way. Give an example.

Figure 1 Fairy mathematics sister

Today's math girl's dress is very fairy, a graceful Chinese dress with a flowing complexion, with a white and red makeup, even through the screen I can smell the fragrance that she radiated when she walks, a sneer Although it looks so cold, this kind of high cold is also a trait that a fairy should hold. The physical handsome guy is also more serious than before. His Einstein-style explosive hair is also very smooth, and he has a solid democratic suit. The shoes on his feet can shine. Two people, walking in the shade of Daming Lake.

Figure 2 Smart handsome guy

Compared with the tension of the physical handsome guy, the mathematics girl seems to be very relaxed. When she sees that the physical brother has not spoken, she has taken the lead in opening the topic. "Physical brother, today, a school brother asked me, is it difficult to be a math or a physics?"

The physical brother was shocked. Is this someone to provoke dissension? "I think physics is more difficult, and mathematics is more complicated." The physical handsome guy still strongly suppresses the inner impulse, pretending to be calm.

"Giggle.", the math girl gave a string of silver bell-like laughter. "Don't you praise me, or is it hurting me? How do you sound it? It’s like saying that our math sister is not that kind of thinking. What is it?"

“不,怎么回事?我的意思是数学姐姐,你给人们一条鱼。”身体英俊的男子很快解释说,他偷偷擦了一身冷汗。

“你什么意思?”数学女孩闪过她美丽的大眼睛,看着身体帅哥。

“你怎么说,你看,我们的物理学非常简单。物理学研究的问题是总结客观存在的那些物体的规律,并总结它们的规律。我将举一个简单的例子。我看到世界轨道和昨天,在现场100场比赛中,博尔特跑得如此之快,以至于他在9秒内赢得了冠军。“ (图3)

我可以使用任何功能在跑道上的任何一点准确地进行定量计算。 (假设运动员的速度是均匀的)我们给出的公式是形式s=vt,其中s是运动员在跑道上的位置坐标,v是运动员的速度,t是运动员离开后的时间。该公式是给出粒子位置与时间之间关系的公式(图4)

“所以,我们的物理实际上非常简单明了。”

数学姐姐插嘴问道:“我们的数学怎么样?你怎么看?”

“处理数学问题的方式是这样的,y=f(x),y是因变量,x是自变量,f是相应的规则。这意味着因变量y遵循约束条件相应的规则f,以及自变量.x的变化发生变化。“

“似乎诀窍没有什么不同?”数学姐姐笑着说。

“仍然存在差异。”身体帅哥呻吟着。

“数学是由鱼教,然后测试:鱼,鲨鱼,鳞片,lu,新鲜,蝎子,蝎子,鲸鱼,蝎子,鳍,蝎子,蝎子,蝎子,蝎子,蝎子,蝎子,蝎子,蝎子,蝎子,Mathematics ,鳟,鲞,,,,鲠,鲐,鲒,,鲽,,鲮,鳄鱼,,鲴,鲷,鲔,鲔,,鲢,鲥,鲺,鱿,,,,,鲭,,鲡,,鳏,鳐,鳢,鲍,,,鲶,鳇,鲎,.”

“啊~~~,哈哈哈~~~”数学女孩已经弯腰笑了笑。

“还有一些共同的特征,都会创造功能,会使用功能的形象。我们的功能是展示事物之间的因果关系。可以说物理学是直接描述使用功能的客观规律,是比喻数学是对法律抽象的概括和总结,更为普遍。“身体帅哥解释道。

“然后我理解,物理问题是一个数学问题。物理学是数学,数学还是数学,这是真的,所以数学比物理学更难吗?”这个数学女孩用假笑说看着这个物理家伙。

图8喝咖啡谈数学和物理

“咳嗽,前面有一家咖啡店,让我们坐下吧。”身体帅哥小心翼翼地试过,不敢拿起话来。

“好吧,我只是累了一点。从你之前的描述来看,数学的内容是包容性的。有一个问题要问你:我们有数学上的极限,连续性和衍生的概念,不知道物理学。你觉得呢?“

“所以,一边喝酒一边聊聊?”

本文关于物理帅哥和数学妹子的第一次约会,就暂时写到这里,我知道大家一定是想知道他们什么时候能牵手。不过我更希望了解,看完本文小伙伴们有没有什么收获呢?敬请期待下一篇,《咖啡店里的极限和导数,物理帅哥,你是我的人》
