Grandma Miao nodded to the two of them immediately: "Teacher Ning, Teacher Ding, write as I discussed with Teacher Ning just now."

Ning Yunxi and Teacher Xiao Ding picked up the chalk and wrote on the blackboard.

Teacher Wu couldn't help but stand by and watch.

The students of the second-year high school class sitting below first whispered below. When they saw the questions written by two teachers on the blackboard, subtle changes in their eyes one by one. Grandma Miao's voice slowly said in the classroom: "Mathematics and physics are two closely linked professional courses. Without the basic calculation of mathematics, many problems in physics cannot be scientifically proved."

The students held their breath all of a sudden.

Grandma Miao spoke tremblingly and her voice was not loud. When the students listened below, they felt that even if they took a breath, they were afraid of missing a word the teacher said. Now what the old man was spitting out is a vast knowledge base as vast as the sea. The amount of knowledge contained in each word can arouse the students' thirst for study.

The students in the second grade of high school were fully focused, and their eyes fell on the white-haired old man on the podium, and they did not dare to leave for a minute and a half.

"For example, the Einstein theory of relativity that we are most familiar with is that without the non-European geometry of mathematics as the principle support, there is no way to make up for it." Grandma Miao needs to take a break after saying it.

Ning Yunxi and Teacher Xiao Ding finished writing on the blackboard at this time. The two of them held Grandma Miao and sat down on a chair.

Grandma Miao shook her hand and said, "It's okay, I'll sit here and watch them do the questions. If you have any questions, ask questions directly and the teacher will answer them directly." Although the old man's tone was not loud, it was like a master in the world who was inspiring the momentum. Looking down at the world, it was like dust, and the world was full of heroic spirit in his palm.

The students listened and immediately dared not underestimate the math and science teachers in the group of elderly, weak and pregnant women.

The beginning of a unique joint mathematics and physics class opened the eyes of students. The classroom is no longer limited to the knowledge in the classroom and textbooks, but is a guide for these students who are about to enter another palace of knowledge in life to look into the sky with higher and wider knowledge in advance.

What is a good teacher? Is it called a good teacher just to explain the knowledge in the textbook? Of course, it is not. The best teacher is to induce students' desire for knowledge and curiosity about the unknown, and to grasp the knowledge and ability to grasp it casually.

To achieve this level of superb teaching skills, unless the teacher himself has an amazing amount of knowledge.

Just like a master takes an apprentice to practice qigong, how can the master teach his apprentice even if he fails?

Teacher Xiao Ding watched Grandma Miao and Ning Yunxi go down to explain the questions to the students, and he holds the teaching assistant's learning notebook in his hand. At this moment, just like the students, he can't hear it. Teacher Xiao Ding just feels that he is not a teacher, but a primary school student who learns from Ning Yunxi and Grandma Miao.

Having said that, Grandma Miao's identity is there, a top scientific and technological worker, for the basic knowledge of high school physics, it is naturally effortless to teach. After reading the textbook, Grandma Miao can understand the knowledge and talk to students without preparing lessons, and there is no need to question anyone.

Where is Ning Yunxi? He is about the same age as him, much younger than Teacher Wu.
