Trên đời các bạn biết thể loại nào tởm nhất không ?. Đó là thể loại pde giả danh tri thức mà nc ra rất thiếu văn hoá.
Và đây là điển hình. 👎🏿👎🏿👎🏿
Anh zai này kiêm bot fun trên Jack’D, khi người khác hỏi về hình ảnh thì gửi mỗi cái face rồi làm như to bằng cục gạch. Tiếp đó như đơn thuần trong 1 cuộc nói chuyện thì ai chả muốn biết cặc him ra sao.
Thế éo nào mà chưởi thằng nhỏ thế nhở.
Éo ưa thì “say goodbye” làm lồn gì nhao mà lại nỡ nói câu biến nghe mún tụt quần dộng dô mặt.🖕🏻
Biết là có fun đi nữa chúng ta cũng nên nc lịch sự và tế nhị chứ con mợe gì mà phải dùng mấy từ ngữ thô thiển này nhở ?

Isaac Newton assumed an inverse square law for gravitation and considered two incompressible perfect spheres with nothing else in the universe. This allowed him to compute the orbits of the planets to tolerable precision. Deviations from these predictions taught us new things: unexpected changes in the orbit of Uranus led to the discovery of Neptune, the anomalous precession of the perihelion of Mercury’s orbit became one of the major proofs of general relativity. We now have far more sophisticated models of gravity than Newton’s, and are working on refining them further.

But you can also tell this story another way. Newtonian orbits gave rise to the idea of a clockwork universe, which turned out to be deeply misleading. In the actual solar system, tidal forces and the influence of other planets on orbits mean that orbits are constantly changing. The solar system does appear to be reasonably stable, but for an entirely different reason than the one suggested by the simplified two-body problem. The adoption of important ideas was delayed due to over-rigid Newtonian thinking.

Obviously Newtonian gravity was a tremendous intellectual advance, and probably a necessary step to further progress in physics. So it is good that some people think this way. But it is also good that some people thought other ways and were willing to come out of left field with inconsistent ideas rather than working on refining existing models. Intellectual history is filled with advances that came about because someone insisted stubbornly that inconvenient observations were correct, and other advances that came about because someone had the courage and insight to ignore observations.
