My mom used to say that when your child is as big as you, you have to treat them with respect. What she actually said was that you had to address them using a respectful form of “anda,” which doesn’t make any sense in English, but may work in Hindi or French. It worked poetically well in Malayalam. I was reminded of this maternal pearl of wisdom recently when I was watching a movie with my son.
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. Ia adalah almost time.
Sejak siri jawatan itu pada Zarah dan Interaksi menjadi sedikit lebih lama daripada saya mahu, Saya fikir saya akan memecahkan ia sehingga. Mari kita mulakan dengan recap fizik moden yang akan anda perlu memahami struktur jirim.
When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, Saya berkata, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. Sebaliknya, 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, benar-benar, is about the interpretations of Quantum Mechanics. The standard interpretation, the so-called Copenhagen interpretation, 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.
Mekanik Kuantum (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. Dan, 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. Really.
Dalam segala usaha saintifik kami, kita menggunakan teknik peringkat tinggi sama untuk memahami dan mengkaji perkara. Teknik yang paling biasa adalah reduksionisme. Ia adalah berdasarkan kepada kepercayaan bahawa tingkah laku, ciri-ciri dan struktur objek yang besar dan kompleks boleh difahami dari segi pengundi mereka lebih mudah. Dalam erti kata lain, kita cuba untuk memahami keseluruhan (the universe, misalnya) dari segi yang lebih kecil, juzuk dikurangkan (seperti zarah).
