How strong is the scientific and technological strength and educational strength of the United States?

Today, the United States is super dominant and super comprehensive, and any opponent seems so pitiful and weak in front of it. The following figures illustrate the strength of the United States in science, technology and education.

First, the scientific and technological strength of the United States

1. The United States has been ahead of Europe for at least 5 years and Japan for 10 years in the most critical information and communication technology field.

2. The expenditure of the United States on R&D is about $30 billion, accounting for 40% of the total global R&D, which is almost equivalent to the sum of the R&D expenditure of the next seven richest countries.

3.20 scientific and technological fields, the United States leads the world 10 fields.

The Nobel Prize is an important indicator to measure scientific achievements and quality. in the past

50

For many years, the United States has been in an absolute leading position in this indicator. In 2004, in this year's Nobel Prize for Science (Physiology or Medicine, Physics and Chemistry) selected by the Royal Swedish Academy, eight scientists won the most prestigious scientific prize in the world, six of whom were Americans.

The United States has networked the best and most essential basic research talents in the world.

Second, the advantages of American education.

1. There are more than 2,300 four-year colleges and universities in the United States, and 1800 two-year colleges are called "community colleges".

Colleges "), its total number is 4 100, which is 8 times that of Britain (228), Germany (368), France (545) and Japan (709).

2. The top universities in the world 10: Harvard University, Cambridge University, Stanford University, University of California, Massachusetts Institute of Technology, California Institute of Technology, Columbia University, Princeton University, University of Chicago and Oxford University. The United States occupies eight positions.

Compare the gap between China and the United States in scientific and technological strength;

Let's look at the gap between China and the United States in comprehensive science and technology and innovation ability. The following picture shows the radar map of scientific and technological strength of 33 industrial fields in China and the United States. The picture divides these 33 fields covering major industrial production into four categories: scientific research, engineering technology, customer-centered and efficiency-driven. The red triangle in the picture is the United States, and the blue diamond is China.

From the figure, we can clearly see that China is ahead of the United States in a few fields such as home appliances, building materials, railways and high-speed rail technology, but it is far behind the United States in more than 20 other technical fields, especially in the core technical fields such as commercial aircraft, semiconductors, biological machines, special chemicals and system software of frontier industries, with a gap of about 20 to 30 years.

In 20 15, among the 49 hot research frontiers and emerging research frontiers in the world, the United States has core papers in 143 frontier, and the number of core papers in 108 frontier ranks first, while China ranks first in 16 frontier, except chemistry and chemistry.

It is reported that in the ranking of the world's top 500 scientific research institutions in 20 15, there are 198 universities and research institutions in the United States, and 9 of the top 10 research institutions are from the United States. How strong is the scientific research strength of the United States? Let's take the Hubble Space Telescope as an example. As we all know, Japan is famous for its high-quality digital camera technology, but in fact, the United States has always ranked first in the world's high-end optical power, not Japan.
