Kategori Arkib: Fizik

Fizik adalah cinta pertama saya. Kategori ini mengandungi jawatan yang paling dekat dengan hati saya. Dua puluh tahun dari sekarang, jika blog ini kekal, kategori ini mungkin akan mengadakan pandangan yang paling lama bertahan saya. Dan dua ratus tahun dari sekarang, jika saya teringat pada semua, ia akan bagi pandangan ini; bukan untuk jenis orang saya, wang yang saya membuat, juga tidak apa-apa lagi. Only for my first and last love…

Zarah dan Interaksi

Baru-baru ini, Saya memberi penerangan mengenai zarah dan interaksi dengan rakan-rakan anak perempuan saya yang merancang untuk perjalanan ke Desy, Jerman dan mahu mempunyai idea tentang apa yang ia adalah semua tentang. Ceramah pertama saya seperti ini, Saya agak gementar kerana saya tidak tahu apa tahap, dan latar belakang, Saya perlu menambat ceramah di. Saya tidak mahu membuat ia terlalu asas, yang saya fikir akan menjadi satu pembaziran masa. Juga aku tidak mahu menjadikan ia terlalu teknikal, yang juga akan menjadikan ia tidak berguna dengan cara yang berbeza.

Sensory and Physical Worlds

Animals have different sensory capabilities compared to us humans. Cats, misalnya, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. Rupa-rupanya, we could hear that high a note only in our childhood. Jadi, 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.

Masalah Free Will

kehendak bebas adalah masalah. Jika kita semua mesin fizikal, mematuhi undang-undang fizik, maka semua pergerakan dan mental adalah disebabkan oleh peristiwa-peristiwa yang berlaku awal. Apa yang menyebabkan ini telah dipilih sepenuhnya oleh sebab yang. Jadi apa sahaja yang kita lakukan sekarang dan pada minit seterusnya adalah semua pra-ditentukan oleh peristiwa yg di dan sebab-sebab, dan kita tidak mempunyai kawalan ke atasnya. Kami pula mempunyai kehendak bebas? Hakikat bahawa saya menulis nota ini atas kehendak — adakah ia betul-betul dan benar-benar ditentukan oleh peristiwa-peristiwa dari dahulu lagi? Ia tidak berbunyi tepat.

What Does it Feel Like to be a Bat?

It is a sensible question: What does it feel like to be a bat? Although we can never really know the answer (because we can never be bats), we know that there is an answer. It feels like something to be a bat. Baik, at least we think it does. We think bats have kesedaran and conscious feelings. Sebaliknya, it is not a sensible question to ask what it feels like to be brick or a table. It doesn’t feel like anything to be an inanimate object.

Lain Conspiracies Dikenali

Teori konspirasi kekal sebagai teori dan makanan untuk crackpots sehingga ia ditiup terbuka luas. Pada ketika itu, yang crackpots menjadi memenangi anugerah wartawan dan pemimpin-pemimpin yang dianggap wira negara menjadi penjenayah sociopathic. Yang demikian itu adalah fickleness berpendapat popular, dan demikian juga dengan 9/11 konspirasi apabila ia menjadi secara meluas diketahui (jika ia pernah melakukan) bahawa ia adalah konspirasi.

The Origins of Gods

The atheist-theist debate boils down to a simple question — Did humans discover God? Atau, did we invent Him? The difference between discovering and inventing is the similar to the one between believing and knowing. Theist believe that there was a God to be discovered. Atheists “tahu” that we humans invented the concept of God. Belief and knowledge differ only slightly — knowledge is merely a very very strong belief. A belief is considered knowledge when it fits in nicely with a larger worldview, which is very much like how a hypothesis in physics becomes a theory. While a theory (such as Quantum Mechanics, misalnya) is considered to be knowledge (or the way the physical world really is), it is best not to forget the its lowly origin as a mere hypothesis. My focus in this post is the possible origin of the God hypothesis.

9/11 Debunkers

Secara peribadi, one of the main reasons I started taking the conspiracy theories about 9/11 seriously is the ardor and certainty of the so-called debunkers. They are so sure of their views and so ready with their explanations that they seem rehearsed, coached or even incentivized. Looking at the fire-induced, symmetric, and free-fall collapse of WTC7, how can anyone with any level of scientific background be so certain? The best a debunker could say would be something like, “Ya, the free-fall and the symmetry aspects of the collapse do look quite strange. But the official explanation seems plausible. Sekurang-kurangnya, it is more plausible than a wild conspiracy by the government to kill 3000 of our own citizens.” But that is not at all the way they put it. They laugh at the conspiracy theories, make emotional statements about the technical claims, and ignore the questions that they cannot explain away. They toe the official line even when it is clearly unscientific. They try to attack the credibility of the conspiracy camp despite the obvious fact that it has the support of many seasoned professionals, like architects, physics teachers, structural engineers and university professors.

Atheism and Unreal God

The only recourse an atheist can have against this argument based on personal experience is that the believer is either is misrepresenting his experience or is mistaken about it. I am not willing to pursue that line of argument. I know that I am undermining my own stance here, but I would like to give the theist camp some more ammunition for this particular argument, and make it more formal.

9/11 – Motives for Mass Murder

In the first post in this series, we saw that 7 World Trade Center building was the smoking gun of a possible conspiracy behind the 9/11 attack. The manner in which it collapsed and the way the collapse was investigated are strong indications of a conspiracy and a cover up. Walau bagaimanapun, when I first heard of the conspiracy theory in any serious form, the first question I asked myself was why – what possible motive could any person or organization have to commit mass murder at this scale? I honestly couldn’t see any, and as long as you don’t see one, you cannot take these conspiracy theories seriously. Sudah tentu, if you buy the official story that the conspiracy actually originated in Afghanistan among terrorist monsters, you don’t need to look for any rational motives.

Atheism vs. God Experience

I have a reason for delaying this post on the fifth and last argument for God by Dr. William Lane Craig. It holds more potency than immediately obvious. While it is easy to write it off because it is a subjective, experiential argument, the lack of credence we attribute to subjectivity is in itself a result of our similarly subjective acceptance of what we consider objective reason and rationality. I hope that this point will become clearer as you read this post and the next one.
