what a shame...
always feel shame whenever seeing a comment like that...
thought people in HK are mostly educated, and would only saying things based on facts...
but in most occasions, that's not the case...
or am I just expecting too much?

佢應該唔係X共,而係(所謂受過高等教育嘅)中產階級,香港好多呢類人都係咁諗;佢地凡事都 instrumentalist thinking,所有野都要 express 做 $$$ 先黎計有冇價值;佢地應該都係「四仔主義」果個年代讀書耳濡目染出黎

"所有野都要 express 做 $$$ 先黎計有冇價值"--> But they ignore the negative externality, another form of cost.

但呢樣一直都唔係古典經濟學 / 自由放任主義經濟學 (斯密 -> 海耶克 -> 佛里曼之流) 嘅範疇, 就好似物理學成日講中微子質量係零一樣

Oh, that's a bit different: the mass of the subatomic particles is so small that can be assumed to be negligible when doing calculation at the macro level: such as Newtonian mechanics, and wouldn't affect the result very much. i.e. a bridge is not going to fall apart if the mass of subatomic particle is assumed to be zero. It matters only when one does calculation at the quantum physics level, such as atomic bomb. To get to the level of creating an atomic bomb, those people must have went through the whole curriculum of quantum physics/ chemistry.

However, the neoclassical economic theory doesn't hold in most real-world situation--just look at how the simple supply-demand theory doesn't hold for the house market of the real-world. Unfortunately, those people who establish policy and law do not need to go through the whole curriculum of different aspects of economics. Even the business school and the undergraduate economics curriculum either do not talk about or put very little emphasis on the fallacy underlying assumption of neoclassical economics in their first class of the More so, a lot of people make judgement based on something they vaguely remember.

Also, basically a lot of those people say things on the internet won't say the same thing in front of other people. They hide behind their computers and most of them do not have to take responsibility of what they said. There is just a news article about that: http://hk.news.yahoo.com/%E6%84% ... 8%B2-224859841.html

A bit off the topic.

How come neutrinos have anything to do with a bridge statics...?
And physicists tend to avoid saying neutrinos are massless because that is one of the major incompatibility of the standard model, but of course, when doing calculation, their mass and momentum is usually ignored, even in quantum physics..

話說今早收到有人share話龍尾泳灘每米費用貴過港珠奧大橋4倍,
但宜加又搵唔返
明明係0係某教授度share出來我自己又有份share.

係咪計錯數?
定因乜事被人要求刪除?

I am just using that as analogy to point out why "物理學成日講中微子質量係零" is different from " ignor[ing] the negative externality, another form of cost", because when the mass of subatomic particles are ignored, it won't threaten lives. But when negative externalities are ignored, it affects a lot of lives (human beings or not).

Well... I don't think that this applies to Lung Mei at all...
If you are talking about metal ions/ heavy metal/ trace minerals, they still belong to atomic level instead of subatomic level.
If you are talking about electrons/ photons, I don't see why they are related to Lung Mei at all.

Besides... the word "negligible" is normally only used for secondary schools/ high schools. A graduated person shouldn't be using it anymore.
Electron does have mass, but the number is a bit difficult for young students to remember, that's why in exams they are allowed to use the word negligible or even 0-- but it definitely does NOT equal to 0.

其實除了保育生態呢個論點, 如果話到俾市民知政府咁做係倒錢落海而受益者只係一小撮人 (唔同起鐵路機場), 我覺得會多啲人支持.

要知道如果真係要個灘游到水, 一年嘅污水處理錢都好甘. 但, 得到了甚麼? 發展水療中心都唔一定要建一個唔游得水的人工泳灘.
