Hua Hua, the eldest son of Hua, was the vice chairman and secretary general of China Medical Foundation. Hua Ling, Hua's second son, followed in his father's footsteps and devoted himself to academic research, but he studied biophysics instead of mathematics. Hua's three sons, like his brother Hua Ling, also entered the China Academy of Sciences for academic research.

China's eldest daughter joined the * * * production party and devoted herself to the democratic revolution. Hua's second daughter, Hua Su, is currently a professor in the Department of Mathematics of Tsinghua University. Hua's youngest daughter, Hua Mi, has worked in the Central Radio and Television University and the Central Audio-visual Education Center.

Hua is one of the founders of modern mathematics in China. He has made outstanding contributions in many fields such as matrix theory, function theory and number theory. His academic achievements and spirit inspired generations of students to actively participate in mathematical research and made brilliant achievements in academic circles.

In the aspect of matrix theory, Hua put forward the famous "Fahrenheit decomposition" theory, which is very useful to solve the problem of matrix eigenvalue and eigenvector.

In function theory, Hua studied the limit properties and uniqueness principle of one-dimensional complex variable functions. Complex variable function refers to a function with complex domain and value domain, which is widely used in physics, engineering, signal processing and other fields.

In the field of number theory, Hua's contribution can not be ignored. He proved the quadratic reciprocity law which plays an important role in number theory.

The significance of mathematics

Mathematics is the key to open the door to science, and it can be seen in all fields of scientific exploration. The wide application of mathematics also provides convenience for our life. From trade, communication and medical care to architecture, aviation and information technology, mathematics has become an inseparable part of us.

Mathematics is also a way of thinking, which can provide us with different perspectives to deal with problems in life. Learning mathematics well will be the wealth of our life.

The story of mathematicians This book selects many outstanding mathematicians from all over the world. Their life stories and lifelong contributions present a complete and vivid image of mathematicians for young readers, so that young people can better understand the development of mathematics and fall in love with it.
