New Zealand church "challenge"

I just read that St Matthew-in-the-City Church in Auckland erected a billboard with the following image:
People found it offensive and defaced it. The church explained that they want to challenge people and think what  Christmas is all about, about the virgin birth or about love. A spokesman for the Catholic Church replied:
"Our Christian tradition of 2,000 years is that Mary remains a virgin and that Jesus is the son of God, not Joseph. Such a poster is inappropriate and disrespectful."
Here we go again. Tradition, no matter how obscure it may be, is put above reason. Whereas I applaud the first church's act to challenge an irrational tradition, I think that, if taken to its eventual logical conclusion, the first church would have to eventually challenge every aspect of its religious dogmas. But then why have a church at all? This is what the critics fear.

A politically motivated conservative organization called Family First, replied:
"To confront children and families with the concept as a street billboard is completely irresponsible and unnecessary,"
This is nonsense. As a child, I loved to be confronted with a reasonable explanation of the traditionally irrational. It made me feel happier and better able to confront the world. Why should children be treated as stupid? Who said that imposing upon them the beliefs and superstitions of a 2000 year old tradition is good for them? The eventual harm done to children by indoctrinating them with irrational absurdities is much higher than a moment's truth.

Those silly pseudo-scientists, II

I just checked Lennox's site, and saw a posting of mine there, a response to other postings, going like this:
The reason that it is ridiculous to bring god/religion into society is precisely because I care a lot about the well-being of all human beings and all life on Earth. Infanticide had been practiced in the name of gods in the past.
The second reason that it is irrational to talk about gods and religions is that there are many gods and many religions. Which one should I choose? By convention, typically, one chooses the gods/religion he/she is brought up with (like Lennox). But why is this a right choice?
The third reason it makes no sense to have religion in our society it is because it makes people lazy: for instance, you think it is a cosmic accident that we are here. You need to spend lots of years and effort in order to understand scientific facts which are not possible to grasp by trivial observations. If someone says “the Bible says so”, most likely this person is lazy.
Finally, let me correct you and others in three of your inferences:
1) Someone mentions the word “random” in their message. I very much doubt that they know what it means.
2) You say I am a leftist. I am not. You also think that being leftist is related to being atheist.
3) Perhaps you are implying that I am atheist. I am not. I am neither atheist nor theist nor deist.
4) Lennox is an ex-mathematician, just as Collins is an ex-atheist. The thing they have both in common is that they use their credentials in order to impress people who don’t have them.
5) Somebody else talks about god (i) as if there is one god and (ii) as if god is male (he uses the male pronoun). Hindus claim there are many gods. Why should I accept one and not two or five and a half gods?
One person replied to me and, among other things, he said this:
One must first investigate the claims of religions, and which one produces the best explanation. Christianity, of course, provides the best explanation and best evidence over any other religion. Saying “there are many religions” does not entail “all religions are false,” which seems to be the kind of logic you are implying here.
Can you see what  kind of mistakes he makes? (Hint: they are underlined.)

Those silly pseudo-scientists

Listen to this guy, John Lennox, explaining why science cannot explain everything. His argument is this:
Someone makes a cake (it is his aunt, Matilda). The chemists can tell what elements the cake consists of. The physicists can tell the particles comprising the atoms in the cake. The mathematicians can describe the equations of motion of these particles. But can we assert that the cake was completely explained? Suppose we ask the experts why the cake was made. They can't tell! But, aunt Matilda can! Of course she can, because she made the cake herself.


I've heard this fellow use this idiotic argument several times in the past. Live. With this argument, he wants to "prove" that science has its limits. And, therefore, he implies that (his) god exists.  Go figure.... The sad thing is not that John Lennox is (was) a mathematician (he is now a priest) at Oxford. It is that he has followers...

There is no limit to human idiocy: "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." (Einstein)

Flip-flopping

November is almost gone, and I have posted almost nothing. Too much work, I guess. Here's what caught my attention recently. The term "flip-flopping" of politicians, with proof. There we go (source):
1) Barack Obama.
2) Mitt Romney.

Funeral office windows, in Sweden

Windows of shops in Uppsala are not quite the most attractive sights of the town. If you have a visitor, don't take her (or him) for window shopping, (unless they happen to have fallen in coma in a remote Soviet village in the eighties, and just recovered from it). Many a times, they consist of nondescript arrangements of random objects, loosely resembling the products of the shop, e.g. a few scattered hairbrushes (often with hair) in a beauty salon, or dull collections of dusty clothes in a neighbourhood fashion shop, and so on--you get the idea. I will have to expand on this in a future email, because looking at shop windows in Sweden is like a time warp. It's like going back to the seventies.

But the most interesting kind of windows are of funeral offices. Typically, we don't see much of decoration in a funeral office window. In most places I've been to they are plain, simple or have religious messages, depending on the type. But in Uppsala (and I think, more generally, in Sweden) some (or all?) funeral offices have very interesting windows. Here is one from Uppsala:



It advertises its products: coffins. A closer look shows the "interesting" and "thoughtful" decoration: scattered stones underneath the coffin, a little (plastic of course) green bush, one side of the coffin standing on a (presumably empty) used can of sardines, a careful arrangement of (yes, you guessed it, plastic) flowers on top, next to a violin (not a Stradivarius, I'm sure). The coffin is locked (who knows why?).

"Interesting", I thought, when I first saw it. And I had to stop my car and take a picture.

What measure theory is about

It's about counting, but when things get too large.
Put otherwise, it's about addition of positive numbers, but when these numbers are far too many.

The principle of dynamic programming

max_{x,y} [f(x) + g(x,y)] = max_x [f(x) + max_y g(x,y)]

The bottom line
