Cultural issues: the need for "authentic soup and authentic food"
Heidegger, a German philosopher, said: Cultural problems can only be solved by methods produced in the soil where this culture is produced. Perhaps because it is too difficult to do so, we would rather save the urgent need through cultural trade. ...
Heidegger probably didn't know the saying that China people "eat the original soup", otherwise he might quote it. Good idea! Good idea! There are still a number of completely westernized groups in our society (although they don't openly play this banner). They should listen to what the western philosopher Heidegger has to say.
The explanation of mathematical weirdo
There are also some weirdos in mathematics, such as Chen Jingrun in China, Nash in the United States, and Erdos, a Hungarian-American mathematician. Why is this happening?
Colmo Golov, a famous Russian mathematician, believes that when mathematics can begin to appear, people's normal psychological development will stop.
Of course, not all mathematicians are different from ordinary people. However, for those math geeks, Colmo Golov's explanation may be worth talking about.
Voice and numbers
Aryabhata, an ancient Indian astronomer and mathematician, wrote a poem in 499 AD, when he was 23 years old. In fact, this is a sine table, and each letter in the text represents a specific number.
Indians have a tradition of "counting by sound" For example, use the 25 categories in Sanskrit (? The original is classified consonants, that is, from K to M, to represent 1 to 25; Eight unclassified consonants, namely from Y to H, are used to express the 30th power of 10 to the 30th power of 10/00; Nine vowels, namely A to au, are used to express the 0 th power of 100 to the 8 th power of 100. Therefore, khyughr = (4x1003)+(2+30)1002 = 4320000.
Why is Indian culture not afraid of large numbers? Is it because Indians are used to tens of thousands of meters of mountains? Isn't it strange that a river thousands of meters wide runs thousands of miles? Why do Indians have the enthusiasm to construct the shortest phrases to express those huge and friendly numbers? In ancient India, people would say that a grammarian would be as happy as having a son if he could omit half a syllable from the expression of a grammatical rule. For ancient Indians, sound is sacred, and one syllable can hold infinity: the smallest word is accompanied by huge numbers.
(Roddam Narasimha, Sine in Concise Poems, Nature, 200 1, 4 14 (6866): 85 1)
I once wrote an essay Science and Music (/blog/user_content.aspx? Id=5 172), "The scientific life of note jumping" (/blog/user_content.aspx? Id=37739), briefly discuss the relationship between science and music. The view of ancient Indians on the relationship between numbers and sounds provides another perspective for exploring the relationship between science and music.
I don't know much about aryabhata. The following is a brief introduction to him from a website in Hong Kong. ( http://www.edp.ust.hk/previous/math/history/3/3_97.htm )
Aryabhata No.1 [Aryabhatai] AD 476-550, India.
He is the earliest known Indian mathematician and belongs to Zusumabro School. He mainly has two works: one is the Almanac of Ayabata, which was written in 499 AD, including astronomical watch, arithmetic, time measurement and ball. This book has ***4 lines, consisting of 12 1. Among them, there are two lines and 33 lines about mathematics, including arithmetic, algebra, geometry, trigonometry and other knowledge. Another book about celestial arithmetic has been lost.
He has made many contributions to mathematics, among which sine table and the solution of indefinite equation are his most representative achievements.
He pointed out that π = (104× 8+62000) ÷ 20000 = 3.1416; In the aspect of making sine table, the circumference is divided into 360 equal parts, and each equal part has 60 small equal parts. Its characteristic is to calculate the length of the half chord equivalent to the current sine line, rather than the length of the whole chord, which is different from that of the vegetable man.
He established the principle of using -ax = c [A, B, C are all integers] to find the general solution of positive integers of an indefinite equation, which was at the forefront of the world at that time, and its method was actually division by turns.
Aryabhata is an important figure in the history of Indian science. In memory of him, the first artificial satellite launched by India in April 1975 was named aryabhata.
