物理学は私の初恋だった. このカテゴリには、私の心に最も近いポストが含まれています. 今から二十年, このブログは存続している場合, このカテゴリには、おそらく私の最も永続的な洞察を開催します. そして200年後から, 私はまったく覚えていた場合, それはこれらの洞察力のためになります; ではない私は人のようなのために, 私が作るお金, でも何か. 私の最初と最後の愛のためのみ…

粒子との相互作用

最近, 私はDESYへの旅行を計画した娘のクラスメートに粒子との相互作用について講演を行いました, それはすべてについて何であったかのアイデアを持っていると思っドイツ、. この種の私の最初の話として、, 私は知らなかったので、私は少し緊張していたどのレベル, そして、背景, 私は、話をペグする必要があります. 私はそれがあまりにも基本的な作りたくありませんでした, 私は時間の無駄だろうと思っています. また私はそれがあまりにも技術的にしたいんでした, また、別の方法でそれが無用にすることになります.

Sensory and Physical Worlds

Animals have different sensory capabilities compared to us humans. Cats, 例えば, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. 明らかに, we could hear that high a note only in our childhood. そう, 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.

自由意志の問題

自由意志が問題です. 私たちのすべては、物理マシンであれば, 物理学の法則に従います, その後、すべての私たちの動きや精神状態は、先に行われたイベントによって引き起こされます. 何が原因で発生することは完全に原因によって決定されます. だから、どのような私たちが今と次の分でやっていることはすべて、事前に定められた先行イベントや原因によって, 我々はそれを制御することはできません. どのように我々はその後、自由意志を持つことができます? 私は自由意志でこのノートを書いていたという事実 — それは完全に、完全に時間の太古からのイベントによって決定されます? それは右の音はありません。.

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. よく, at least we think it does. We think bats have 意識 and conscious feelings. 一方, 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.

その他の既知の陰謀

それが広く開い吹き込まれるまで陰謀論はcrackpotsのための理論と飼料のまま. その時点で, crackpotsは賞を受賞したジャーナリストや国民の英雄が反社会的人格障害の犯罪者になると考えられていた指導者になります. そのような物は世論の浮気です, そしてそれは、とされます 9/11 それは広く知られているなると陰謀 (それは今までにない場合) それは陰謀だったこと.

The Origins of Gods

The atheist-theist debate boils down to a simple question — Did humans discover God? または, 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 “知っている” 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, 例えば) 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

個人的に, 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, “はい, the free-fall and the symmetry aspects of the collapse do look quite strange. But the official explanation seems plausible. 少なくとも, 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. しかしながら, 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. もちろん, 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.
