The appearing person

Here's a tricky logic puzzle. Count the people before and after the picture changes.
(I have it half figured out.)

Quantum fits

In a comment to the Illusions post, Pascal gets Quantum on our asses:

“God does not play dice” - Einstein

To which Louis de Broglie replied: “And who are YOU to tell God what He can do?”

The quantum uncertainty principle is just as much a fundamental fact of Science as the light spectrum of atomic Elements.
Basically, it states that if God doesn't play dice, only He can ever know it.
Or, more matter-of-factly, that if you imagine quantum particles in the Universe as ants in a colony, there is nothing smaller than an ant that you can send in to gather information, but your added robot-ant will disturb the information by its presence. "Oi! Move on, buddy, I've got corn grains to carry here! Make yourself useful, go guard the Queen's Chamber with those big choppers of yours. And watch where you put your feet, will ya? Sheesh..."

Here's a simple example of the uncertainty principle:
A spectral line represents a given wavelength of light (or other energy emission). But a spectral line always has a certain width, amounting to a frequency range. Why is that? Because the laws of physics show this: if there was only one, mathematical photon wavelength, one exact frequency instead of a narrow range at best, its energy would be infinite. It would amount to dividing a given intensity by a width of zero. Even with one single photon, this still applies. There's no escaping it, just like death and taxes. ;-)

As soon as you get a little far above a beach, it appears as a continuous surface. But at a small scale it'll always be made of grains, and its physical properties will differ from those of a true fluid or a normal solid. Which will be noticeable even at a scale far bigger than grains.
Inversely, under a moderately powerful microscope, sand will appear as a heap of tiny rough rocks. It may appear in very different fashions, none of which is truly representative of what we can only understand with mathematical tools, namely "the big picture". Sand is a peculiar solid (a "grainy matter") that sometimes behaves like a liquid. When you stroll on a beach, you have the illusion that this can't happen... until a sandstorm rises, Allah forbid!

Mud is even more complicated in behaviour, because it's grains closely mixed with liquid, at a scale where tiny surface forces have a tremendous cumulated effect.
Did you know that tar is actually a liquid? Hit it with a hammer, and it shatters. Leave it in a pierced barrel, and it'll run. Veeeeerrrrry slooooowwwwwly. It is viscosity at a very unusual scale. Glass is similar, in reality. It is an incredibly viscous amorphous solid. A window could theoretically become a puddle on the floor at ordinary temperature. The thing is, it would take millions of years, provided erosion doesen't get it first! Its stability is purely an illusion created by our own time scale. Compared to minerals, we live very fast dog years...

Our senses are sophisticated measure instruments, which give us a reprepsentation of the world, in a certain fashion which is USUALLY the most efficient. For who and what we are. But they have their limits, all of them put together still have their limits. Only with our intelligence can we get past that illusion... one slow step at a time.

Given enough speed and kinetic energy, a water-filled balloon can go right through the armor of a battle tank like a red-hot knife through butter. Unless the air friction evaporates it first in a cloud of steam. A feather in the void of space could possibly kill an astronaut, because no air slows it down. We're just not used to such things happening. We live in the illusion of our habits.
An infant could move an aircraft carrier with one hand. In the wieghtlessness of space, or even in a very calm water harbour. All it takes is the patience to overcome the inertia of a great mass and wait till you see a visible result, so keep pushing!
The fragile silk sheet of a parachute can hold a man in the air. A spider's silk is way tronger than steel or Kevlar, and would make great (and lightweight) bullet-proof vests. It would seem that an unarmed frail cleric could halt the Scourge of God with mere words.

So, always beware of what you take for absolutely and universally certain. Keep an open mind. We only know as much as we have already learned or discovered, and yet not always.

Illuuuuusions!

More and more "hard scientists" are saying what Buddhism, Hinduism, and many other spiritual traditions have told us for millennia: the universe is illusory.

Ed Viswanathan added:

Thanks for a thought provoking blog.

In the Hindu Bhagavad Gita 9:7,8, Lord Krishna tells his friend Arjuna

“ Through my MAYA [ illusion], in the beginning of time, I create everything and at the end of time KALPA, the whole creation merge in me. By my will the whole universe is created & annihilated again and again “

God alone exists and everything else is Maya or illusion.

Stressing the cyclical nature of creation and Destruction, Lord Krishna said in the Bhagavad Gita:

“I AM LIFE, CAUSE OF ALL LIFE AND I AM DEATH, DEVOURER OF ALL."

This whole process is known as LEELA or CHILD PLAY OF GOD in Hinduism.

Just like the ON and OFF switches on a digital computer makes thousands of forms of "illusion" for all of us, through Maya, God is creating all the illusion again and again.

That is the reason why Hindu salvation is known as SELF REALIZATION. That means REALIZING one is the immortal soul or Atman within and not the perishable material body which is MAYA.

Predictability and TV shows

Either TV shows are predictable or I'm damn sharp. (Let's not eliminate the option "both". :)

I rented the first disk of the TV Show "House", with Hugh Laurie. I knew nothing about it, only that it was respected and that I tend to like Mr. Laurie's work.
So I start the first episode... there is a good-looking young woman hurrying from a bus to get to work on time. I see the way it's filmed, and I think to myself: "Ah, she is dead. I give her two and a half minutes."

Exactly two and a half minutes later: bam! she hits the floor.

I have to admit though, that since it turns out to be a "medical drama" and not a crime show, she was not dead. The drama of the week is the doctors rushing to find out what's wrong with her, not the police rushing to find her killer before he kils again.

Boooooring.

Gandalfe counters:
My wife the nurse and I luv this show. Not so much violence as more of a who done it. And there was a rather nice piece done on a jazz pianist losing his touch. To each his own I suppose.

OK, I admit I just tend not to like drama very much. Could be me.
------
Oooh, by the way, have you noticed that people never finish their drinks in films and TV shows? They get a lot of dialogue out of the way fixing the coffee or juice, and then they are done talking, and the guests leave without touching their drink. All the time. A very weird world they live in. :)

Hive Mind

A parallel and similar development in human consciousness is: the development towards the Hive Mind.
A Hive Mind is traditionally a scary thing which has only been in use by fearsome aliens in SF novels. But it might be a good thing.
It used to be that good art of craft was almost always only found in products coming from individual artists or crafstmen (or inventors, or thinkers...). But the times are going towards collaboration.
Just one example is that it now rapidly becoming more reliable to read several reviews of something (a book, camera, computer...) online than it is to rely on the advice on a salesperson in a main street dealer.

Privacy

One of my fond beliefs has always been that privacy is one of our holiest posessions. But I'm beginning to reconsider, difficult though it is. After all, another of my fondest beliefs is that openness and communication are the most valuable things to pursue, and it does not really go with the other thing, does it?

Also, more and more I believe that threats are created by our fears, not vice versa. So work on stilling your fears, not eliminate the threats.

Here's an article with a fresh view. Quote:
"So it may be time to consider the possibility that young people who behave as if privacy doesn’t exist are actually the sane people, not the insane ones. For someone like me, who grew up sealing my diary with a literal lock, this may be tough to accept. But under current circumstances, a defiant belief in holding things close to your chest might not be high-minded. It might be an artifact—quaint and naïve, like a determined faith that virginity keeps ladies pure. Or at least that might be true for someone who has grown up “putting themselves out there” and found that the benefits of being transparent make the risks worth it."
Another one:
"At 17, Oppermann is conversant with the conventional wisdom about the online world—that it’s a sketchy bus station packed with pedophiles. (In fact, that’s pretty much the standard response I’ve gotten when I’ve spoken about this piece with anyone over 39: “But what about the perverts?” For teenagers, who have grown up laughing at porn pop-ups and the occasional instant message from a skeezy stranger, this is about as logical as the question “How can you move to New York? You’ll get mugged!”) She argues that when it comes to online relationships, “you’re getting what you’re being.”"

I agree. It's profoundly healthy, this mind shift, hard as it is to get used to. This whole "don't talk to strangers" thing of the 20th is not prudent, it is negative and counter-productive.

It's a new world with new kinds of communications that us "oldsters" don't understand. I don't get how a site like Noah K Everyday is useful to anybody, but it fits perfectly in the new world. Bless 'em.
[Thanks to TTL for pointing to the NYC article.]

TTL advices:
I find that people in general are not interested in solutions. It is the problems they are excited about. When you present people with a simple and true solution to any big problem, they go all quiet and quickly change the subject. On the other hand, if you only talk about the problem their eyes lit up and they start 'sympathising' with you. Some people get so excited about reiterating the problem and calling for a solution that foam comes out of their mouth.

Whose Computer Is It?

Walt Mossber column: Whose Computer Is It?.
See, that is one of the most important reason I've stuck with Apple since the mid-nineties: apart from better usability, Apple works for customers, not sponsors or middlemen. Apple respects the customer.

Do Ya Think I'm Sexy

Remember the Rod Stewart hit "Do Ya Think I'm Sexy"?
Ready for a decidedly non-family version? Enter The Revolting Cocks. (It means The Rebellious Roosters, obviously.)
OK, the video is silly (and not for the tender of sensibility), but the music rocks.

What I really wanted to post was their much newer song "Pole Grinder" which is amazing. But it does not seem to be on Utoobe.

Nikon vs Canon

If you have any interest in high-end cameras, either practical or intellectual, here is a very observant article about how the Canon/Nikon battle is going. (Hint: Nikon is losing ground fast, it's sad.) (Note, this is only true in the high end, not consumer cameras. Under $1500, Nikon rules.)

ttl commented...

Well, there must be an order of magnitude difference in the size of the R&D budgets of these two companies. The fact that Nikon is able to compete at all is pretty amazing.

It seems to me these Nikon-is-a-has-been statements and articles appear regularly at the point in the product life cycles when the flagship Nikon camera has been in the market for quite some time and Canon has just come out with their latest and greatest.

Still, as I wrote earlier, Canon is constantly one step ahead. But if Nikon starts falling two far behind one might expect them to join forces with some other player, and then the competition would start anew.

JB adds:
It seems to me that Nikon has just made the marketing decision to push at the low end of the DSLR market. The D40 and D40x show this. They do not produce their own chips and Canon does. So Nikon is doomed to take what Sony hands them while Canon can innovate and produce sensors like the 14 bit Mk III. Nikon cannot compete in this arena.

Canon on the other hand has made the marketing decision to compete from the mid level to the top in the DSLR world. Their entry model 400D is competitive with the Nikon D80 leaving three Nikon models in the region below this.

Canon has possibly decided that the profit margin is too low in this area when you had a pack of wanna-be competitors like Pentax and Olympus driving the prices down.

So I don't think Nikon is failing, they just have a different plan which is based on their suppliers. Time will tell which is the most successful.

Of course Nikon cannot afford to fall completely into the shadows in the upper end of the market since that would damage their sales at the bottom. So they will have to come up with something to compete with the Mk III and the eventual 40D which we can assume will have some Mk III features.

Susie Bright on fantasies

"It’s normal, it’s common, to fantasize about the bizarre— the things that in real-life circumstances would trouble us, frighten us, or maybe just make us laugh. Erotic fantasies take the unbearable issues in life and turn them into orgasmic gunpowder."

Canon rebate scam

Last year when I bought a Canon 5D it had a mail-in rebate of £200. It took ten months and multiple e-mails and snail-mail letters to finally get the check.
I had a suspicion I was not alone. This proves to be the case.
It looks like Canon and others like them are doing it on purpose, saving big money on the big percentage of customer who just give up or forget. This is dirty business, and these companies should not be doing it.
A similar thing from Sandisk.

JB enlightens:
"Well they had a problem in the US which was blamed on the company they used to process the rebates. Canon USA promptly made public apologies (on forums and blogs) and created a way to register your rebate request on their website. This was supposed to speed up processing.

When I submitted my rebate request after they had done that my rebate was processed and in my hands within 3 weeks, maybe a bit less.

So perhaps the Canon Europe managers have been less active in fixing the problem. I haven't heard any complaints after the initial problem was fixed here in the US."

They made apologies on forums and blogs? Really? I've never heard of a big company doing that.

JB expands:
This is the message that was sent to several forums/blogs by Canon:
--------------
"Hi, Folks:

Let me assure anyone who is interested that Canon U.S.A. takes the issue of
customer satisfaction very seriously. It's not by mistake that the PC
Magazine Readers Survey has rated us #1 in digital camera after-sales
customer satisfaction for the past 3 years in a row.

We are sincerely dedicated to honoring legitimate claims for our mail-in
rebate programs. Towards that end, we recently set up a new system on our
website that allows customers who qualify for rebates to expedite their
requests through a pre-qualification process. Please visit the following web
page and click on "PRE-QUALIFY YOUR REBATE" for details.

[They had a link here but blogger doesn't like it]

In addition, we provide a toll-free dedicated support line for rebate
requests through our Customer Support Center at 1-800-828-4040, and there is
also a dedicated e-mail address for assistance on rebate claims:
