Mathematics and life works (analyzing the mysteries of life with mathematical thinking)
Mathematics is closely related to life, and mathematical thinking can help us better understand various phenomena and laws in life. This paper will analyze the mystery of life through mathematical thinking and explore the relationship between mathematics and life.

Chapter 1: Mathematics and Time

Time is an indispensable part of our daily life. We need time to arrange our schedule and plan our future. But how is the time calculated?

1. 1 origin of time

The origin of time can be traced back to the history of human civilization. The earliest time unit was days, and people calculated time by observing the movements of the sun and the moon. Later, people invented timing tools such as water clock and hourglass, and the time unit was gradually refined into hours, minutes and seconds.

1.2 calculation of time

The calculation of time is based on the conversion and addition and subtraction of time units. For example, we can convert 1 hour into 60 minutes, and 1 minute into 60 seconds, and then add and subtract. In addition, we can also measure time by clock. The principle of the clock is to use mechanical or electronic devices to keep the time stable and accurate.

Chapter 2: Mathematics and Space

Space is another important aspect of our life. We need to locate, navigate and plan in space. But how is space understood and described?

2. 1 space geometry

Space geometry is a subject that studies the shape, size and position of space. Euclidean geometry is the most common geometry, which describes the nature and relationship between plane and solid figure. In addition, there are non-Euclidean geometry, differential geometry and so on.

2.2 spatial coordinate system

Spatial coordinate system is a way to describe spatial position by mathematical method. The most common coordinate system is Cartesian coordinate system, which consists of three mutually perpendicular coordinate axes, representing three directions in space respectively. Through the coordinate system, we can use mathematical language to describe the position, distance and angle in space.

Chapter 3: Mathematics and Statistics

Statistics is a subject that studies data collection, analysis, interpretation and prediction. In life, we need to understand the phenomena and laws in social, economic, medical and other fields through statistics.

3. 1 data collection and analysis

Data collection and analysis are the basis of statistics. When collecting data, we need to determine data type, source, sample size and other factors. When analyzing data, we need to use various statistical methods to describe the distribution, relationship and trend of data.

3.2 the application of statistics

Statistics is widely used, which can help us understand social and economic phenomena, medical and health conditions, environmental pollution and so on. For example, we can predict the stock market trend, evaluate the medical effect and analyze the degree of environmental pollution through statistics.
