Education Changes Life and Education

Yesterday, a friend who advocated the idea of "education changes life, we change education" came to my house to see me and sent a pot of flowers to bless my birthday. On July 6, 20th day of this month, he held a wedding ceremony with Ms. Xu and invited me to attend. I wish them a happy and happy marriage!

Review history: In 1675, Leibniz, German mathematician, invented the infinitely small method and used it to create calculus.

In 1875, German mathematician K. Weierstrass established the (ε, Delta) Extreme theory, evict the infinitely small from calculus.

In 1960, German mathematician Robinson (A. Robinson) used the mathematical logic model theory to restore the reputation of the infinitely small method invented by laveniz and created the theory of super real infinitely small.

In 1976, J. Keisler applied Robinson's infinitely small theory to college mathematics education for the first time and achieved great success (represented by basic calculus ).

In 1908, calculus was first introduced into China. In 1954, the Chinese version of the former Soviet Union's "calculus tutorial" was published. From then on, large-scale modern calculus Education in China started. In 1978, Tongji University published "Advanced Mathematics", which was extended to the present (sixth edition) and became the "11th Five-year Plan" teaching material for general colleges and universities in China.

In 2013, the infinitely small calculus pocket e-books appeared on the Internet for the first time in China. So far, it has become a new sign, and this action has aroused the attention of J. Keisler himself.

Elementary written by J. Keisler
Calculus: an infinitesimal approach (basic calculus). It was sent from Shenzhen via express mail in July 15 and is expected to be delivered to me in July 17 as a birthday gift. With this book, we will contact the relevant publishers in China for the translation and publishing of this book, and we will also contact the relevant education departments for how to conduct education pilots.

From the perspective of pocket e-books "section 6.6 some physical application", the infinitely small method will further affect the Teaching Reform of China's basic education system (such as high school physics, it can be said that it is a "Pull-and-pull" business.

At present, although there are very few or even a few people who are paying close attention to the "infinitely small calculus" pocket ebook, the infinitely small calculus is basic science rather than news propaganda. After many years, and will not be gradually forgotten by people out of date. Now, although I have never used it, I have a few little helpers who are "easy to understand.

Note: in essence, Robinson's infinite small method is to defend against the modern mathematics of the lateniz infinitely small calculus in that year, and we are all the "disciples" of laveniz. Learning calculus is a real "Strange Way" without learning anything (super real). Time will tell you everything.
