Chapter 626: Sadly urging the beginning of the student era

Han Yu Xiaotian was obviously also extremely uncomfortable with the rune-breaking method that suddenly appeared in front of him, so this felt a little out of place.

However, what he didn't know was that the future that will flood his student life is not only calculation and analysis!

Mathematics, philosophy, energetics, composition, material science, space geometry, fluid mechanics...

Han Yu Xiaotian's sad reminder of the student era has just begun.

"Students, applied differential calculus is an extremely old subject. It is a branch of mathematics used to study the graphical properties of curves and surfaces in three-dimensional Euclidean space. It originated in the earth age almost at the same time as calculus. century.

The geometric image of a univariate function is a curve, and the derivative of the function is the **** of the tangent to the curve. The integral of a function can be understood geometrically as the area under a curve and so on. This application of calculus to curves and surfaces is essentially the beginning of differential geometry..."

"Philosophy can be seen as a measure.

The function of this scale is to start from the rational existence itself to find the essence of rationality and the relationship between self-existence and other existences in the world.

Philosophy is meta-knowledge and meta-science, the so-called great way to simple. The philosophical task is to grasp the real world at the elementary level, to synthesize many into one or distinguish one into many, and one and many are all elementary principles. Yuanli must also be expressed clearly and structured systematically, so that such a metali system is suitable for interpreting the world or guiding practice.

Philosophy is elementary theory, science, metaphysics, and art are principles, methods, and facts. When it comes to the study of runes, what I want to emphasize to you is that thinking determines everything!

Only thinking can determine whether you can finally comprehend the runes and determine where you can go in the future. So please don't ignore the importance of philosophy! "

"Do you really think you know the universe?

Then I can tell you responsibly that I was wrong. Now I will explain to you what the universe we humans currently see looks like.

First of all, the many exoplanets we have discovered so far belong to giant gaseous planets, often several times the size of Jupiter, and are orbiting very close to the star. The Spitzer Space Telescope found a planet with a surface temperature of 1,000 degrees Celsius. , "Bathing" in the terrifying heated jets of stars throughout the year...

Kepler-78b is about 400 light-years away from us. Its size is very close to that of the earth. It may have an iron core. Such similar characteristics cannot guarantee that the planet is habitable. On the contrary, it is under the control of the star fire monster.

The United States discovered that there is a mysterious alien liquid flowing out of the surface of 55 Cancer ê. There may be a huge amount of material inside this super-Earth. Because it is very close to the star, there is almost no complete ground on the surface, causing the liquid below the surface to begin Ooze.

Gliese1214b is a planet that is cooked alive. The strong pressure makes the planet like a planetary pressure cooker. If you enter this planet, you will soon experience the feeling of being in the pressure cooker.

In ancient legends, the aurora is the soul of the dead, as if in a world full of aurora, then what kind of scene? As early as 200 years in the galactic calendar, scientists discovered an exoplanet with diffuse aurora across the entire planet. The brightness is 100 to 1000 times that of the aurora on Earth.

PSOJ318.5-22 is a very free world, because it is out of the control of stars and floats arbitrarily in the universe, but scientists believe that this may be a failed star, in short it is a "lone ranger... ."
