Is Theoretical Research Useless? Don't Cry When Water Drops Hit Your Face!

This book is not that poisonous. After all, some very brainless white articles can be written. But for readers who are more rigorous, it will be more uncomfortable. To be honest, if some plots could be deleted, it could be used as a popular science book for children. Just one hundred thousand whys. Or simply go back in time to a timeline where empiricism was more developed but technology was not valued (as the previous book review said, this can only be limited to the 19th century). In addition, theoretical physics is not an empty physics and also requires sufficient experiments.

At this time, a space located in the universe - the observable universe - Hercules - the Great Wall of Corona Borealis - the KBC void - the Sloan Great Wall - the Pisces - the Pisces supercluster complex - the Lanikea supercluster - the Virgo supercluster - the local galaxy group - the Milky Way subgroup —Milky Way—Orion Arm—Gould's Belt—Local Cluster—Local Bubble—Local Interstellar Cloud—Oort Cloud—Solar System—Heliosphere—Inner Solar System—Earth-Moon System—Earth A handsome boy from Guangdong Province, People's Republic of China passed by and liked it 🙂

Don't forget, even if you are so boasting about theoretical technology, you still have to make water drops. The sooner it can be applied in practice, the better, otherwise it will just be the NPC missing his right leg and the protagonist missing his left leg.

Just reading the introduction makes me feel like my IQ is rapidly declining.

The middle section is cleaner than the infinite size. If you have studied advanced mathematics, you will be extremely physically uncomfortable. Because the proof given by the author is very elementary school student, the persona is to promote theoretical physics, but the proof given is full of intuition, which is very outrageous. But the good news is that if you have never studied advanced mathematics, you can read it with confidence. It's good to just popularize some knowledge. The author's proof is similar to what my elementary school teacher said when he gave us popular science. It is easy to understand.

Pay attention to application, ignore theory, and then the level is equivalent to reality? So how do we achieve the destructive power of nuclear warheads with a yield of dozens or millions of tons in reality? Build a 100-meter-caliber cannon? How is a computer with ultra-high computing speed achieved? Build a mechanical computer that can fit within dozens of square kilometers?

To be honest, I haven't read the book. Just by reading the title, I knew it was a short article. Theoretical physics has always been ahead of experimental physics, and it is much ahead of it. It is the basis of experimental physics, the foundation. If there is no foundation, what is it, a castle in the air?

Ancient Chinese astrology and agriculture were the four great inventions. The ancient Western geocentric theory. (In fact, the existence of architecture shows that structural science has developed to a relatively high level) In ancient times, there were many woodworking and metalworking tools. Basically, there was no theory to guide practice, and most of them were theoretical explanations of practice. Tables like artillery operations can also be derived from test firings. But once you enter complex system engineering, such as starting with a steam engine, the cost of trial and error through experience will be greatly increased. It is impossible to try all the many parts of a steam engine →_→. If there is no clear scientific theory, the historical process may be fixed in the 19th century. There is no way the computer described in the book could exist. Of course, our current scientific theories are not complete enough. For example, the essence of aerodynamics is the ns equation, but we currently do not have a general solution and can only use some empirical formulas. For example, there are still many unknowns about the Standard Model and the Grand Unified Theory.

How to make semiconductors, how to invent universal electronic computers and the Internet without understanding the laws of electronics

It can't be considered a science fiction novel, but an urban novel.

The pretense part is okay, but the emotional line is stretched.

After reading the introduction, I am afraid that the author did not understand the relationship between theoretical science and applied science 🙂

You can say that theoretical development lags behind, but it cannot be completely black box, otherwise the early days of the electronic age will be the peak.

This novel is definitely a bad one. If it wasn't for Tai Yin, I would have washed my hair while standing on my head. Pretending to be cool is too slow. Most of the whole text is scientific theory, which is equivalent to copying directly. Anyway, the plot is not interesting enough, blunt and watery.

After reading the introduction, please save your brain here and read it again.

What do I think? If you have no theory, how did you get the previous application?

Why did I discover this book so early? There are only a dozen chapters 😫

Draw a pie. You can't make it either. No system support

There is no need to boast about theory and disparage application. Theory is the direction, and practical application is to test the theory. Just like nuclear fusion has theory but cannot be applied, it still cannot be realized. It is always said that it will be successful in the next 50 years. Theory and application complement each other and are indispensable. If your theory is great but your application cannot keep up, your stuff just can't be made and it's useless.
