Industry and college students don't know how Microsoft is recruiting employees to give him
/
She took a test question. At first, he looked like a question of a few brains. For example, an old sow crushed with six pigs, two in the top, three camel on the side. The number came over, asked what happened, the answer is the number of old pigs, it is not, Microsoft is indeed a great company.

It is necessary to find the most intelligent person in the world to work with him. He is going to be a US talker. He carefully studied Watson's "genetic molecular biology". He may want to use only four status values to do software because the cremers create life. with

The method used by the industry is the same is the code, Microsoft is the earliest use.
Bayesian
Theorem solves the problem of spam issues. The Chinese people think that the blame is difficult for the candidate, it is also a Microsoft, which is not.

In the year, he won the Bell Physics Award.

In the United States, the first atomic bomb explosion site, Fermi threw the tearned paper, estimated the explosion equivalent to estimate the distance of the origin under the explosive shock wave, resulting in the results of the computed calculation of the computer, Fermi is estimated the number of physical quantities (
ORDER of MAGNITUDE
The method is also one of the main methods of physics research until now. Fermi problem (
Fermi Questions / Problems
In the case of incomplete information is incomplete, it is scientifically imposed and improving the subject matter. It is scientifically made to make the problem simplified, and the complexity is reduced, which is in line with or close to the actual estimate. The extent to which the researcher grasped the object of the study, with classic mechanics principles to quantify the quantum mechanics, the phenomenon of the masters, the intelligence games that the masters are often happy. There is no similar to Fermi issue, and the professor and learning of China's education advocates standard answers. use
You can find many of the information about Fermi issue, very fascinating, this will not be described. In my opinion, this is not a sculptor, there is a math master to say that the trial of the trial is a standard method.
In fact, social economic phenomena is more suitable for the use of Fermi issue, because the accurate calculation here often does not make sense, and the estimation of the order of things is indispensable, we are only willing to calculate the risk; This method has developed an economical genre, the economy, the size of the market, the market capacity, the number of consumers, traffic, product replacement ratio, price sensitivity, price, elasticity, etc. I often use this method when I deal with market things, at least you will not make too stupid decisions, when I operate a secondary book wholesale company, I have a new city for two hundred to three million people. The general martial arts novel published, in the case of exclusive operation, consumption will not exceed 3,000 books.
