Triết học không bao giờ là quá xa vật lý. Đó là chồng chéo của họ mà tôi mong đợi những đột phá.
Life is full of contradictions.
I am attending a research retreat on mindfulness and contemplative practices at the beautiful Garrison Institute. I am learning a lot of interesting things, and meeting a lot of like-minded and excellent people – the kind of people with whom I could have deep conversation about the unreal nature of reality, unlike most people from other walks of life would politely and tactfully excuse themselves when I get a bit unreal.
At some point in our life, we come to accept the fact we are closer to death than life. What lies ahead is definitely less significant than what is left behind. These are the twilight years, and I have come to accept them. With darkness descending over the horizons, and the long shadows of misspent years and evaded human conditions slithering all around me, I peer into the void, into an eternity of silence and dreamlessness. Đó là almost time.
Kể từ khi loạt bài đăng trên hạt và tương tác trở thành một chút còn hơn là tôi muốn, Tôi nghĩ tôi sẽ phá vỡ nó lên. Hãy bắt đầu với một bản tóm tắt của vật lý hiện đại mà sẽ bạn sẽ cần phải hiểu được cấu trúc của vật chất.
Unreal Blog recently got another award as one of the đỉnh 100 philosophy blogs.
Các previous such award came a few years ago. Glad to feel appreciated for my efforts and to see that people are taking notice.
When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, I said, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. Mặt khác, Special Relativity is about macro objects in motion, and we have no problem imagining such things. So why would we need to have an interpretation? The answer is a subtle one.

Whenever we talk about Quantum Mechanics, one of the first questions would be, “What about the cat?” This question, thực sự, is about the interpretations of Quantum Mechanics. The standard interpretation, cái gọi là giải thích Copenhagen, leads to the famous Schrodinger’s cat.

In this post on Quantum Mechanics (QM), we will go a bit beyond it and touch upon Quantum Field Theory – the way it is used in particle physics. In the last couple of posts, I outlined a philosophical introduction to QM, as well as its historical origin – how it came about as an ad-hoc explanation of the blackbody radiation, and a brilliant description of the photoelectric effect.

Cơ học lượng tử (QM) is the physics of small things. How do they behave and how do they interact with each other? Conspicuously absent from this framework of QM is why. Why small things do what they do is a question QM leaves alone. Và, if you are to make any headway into this subject, your best bet is to curb your urge to ask why. Nature is what she is. Our job is to understand the rules by which she plays the game of reality, and do our best to make use of those rules to our advantage in experiments and technologies. Ours is not to reason why. Thực sự.
Trong tất cả các nỗ lực khoa học của chúng tôi, chúng tôi sử dụng các kỹ thuật cao cấp tương tự để hiểu và nghiên cứu điều. Kỹ thuật phổ biến nhất là giản lược. Nó được dựa trên niềm tin rằng các hành vi, tính chất và cấu trúc của đối tượng lớn và phức tạp có thể được hiểu theo nghĩa của các thành phần đơn giản của họ. Nói cách khác, chúng tôi cố gắng để hiểu được toàn bộ (vũ trụ, ví dụ) về nhỏ hơn, giảm thành phần (chẳng hạn như các hạt).
Animals have different sensory capabilities compared to us humans. Cats, ví dụ, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. Rõ ràng, we could hear that high a note only in our childhood. Vì vậy,, if we are trying to pull a fast one on a cat with the best hifi multi-channel, Dolby-whatever recording of a mouse, we will fail pathetically. It won’t be fooled because it lives in a different sensory world, while sharing the same physical world as ours. There is a humongous difference between the sensory and physical worlds.
