Iridium flares

iridium satellite I was reading about the satellite collision between a Russian and an American satellite over Sibiria, and stumbled upon the Heavens-Above website. You can enter your geographical data, and among other things see when you next time can watch a so called Iridium flare, which is a reflection of sunlight from a Iridium satellite. The American satellite, which yesterday collided with a Russian satellites, is one of these Iridium satellites, and their antenna shapes makes them reflect sunlight so it can be seen on earth.

I’m pretty sure I have seen it once, but can’t be entirely sure it was a satellite. But now at least I have an opportunity to actively pursue it. I guess it could be pretty cool. But why do all science websites have to be butt ugly?

Obama and the arbitrary entity known as ‘God’
  icon1 Brian Zhang Larsen | icon2 Uncategorized | icon4 01 26th, 2009| icon34 Comments »

How would an american presidential candidate handle the “Christianity” issue, if he was not really religious himself? I have been asking myself this question, while I have a hard time seeing Barack Obama as truly Christian, the obvious intelligent being he is. I am not stating in any way, that a religious person is not intelligent per definition. There is a lot people in history that proves the opposite. But as a strong non-believer myself, I have a really hard time imagining how anyone, grown up in a modern society, can honestly say to themselves that God exists as a divine being, listening to one’s prayers.

Perhaps Obama really is Christian, as he so proclaims. I certainly do not see him as a liar, although as a politician at his level, he must master the art of spin to some degree. Every modern American president has been Christian to some extend. Only some of the very earliest presidents, those known as the founding fathers was not clearly Christian, even though this is still discussed. Some is now labeled as Deist, which is as much non-religious someone can be while still being slight religious. But perhaps that was just a word atheist invented, in order not to let their mothers entirely down. Or perhaps it started something like this:

“So, what Church do you follow?”
“I’m not religious. I don’t really believe in god?”
“Huh?”
“I belive the truth lies in trial and error, proving and falsification.”
“Ok, listen there clearly IS a God jerk, but you like that science thingy too? that’s nice. I guess we could call that Deism”

Not only can the founding fathers religious view be questioned, but they were also rational enough not to include anything religious in the constitution, making it an entirely secular document. A very smart move, viewed in retrospect. By including religion in this document, they could have accelerated the Christian fundamentalism the country is struggling with today. Today however, in Americas current state it is hard to imagine a politician running for president, who is not Christian, and still having a shot at the post.

This makes me suspect that a rational non-believing person, that have the urge to change things for the better, might need to change the public perception of certain personal beliefs. And while religious belief is a highly intangible arbitrary phenomenon, this could be quite easy to fake, if one should feel the need. And maybe because I had the suspicion, and was looking for clues, I think i found them in Obamas book “The Audacity of Hope”. In a chapter about faith, he writes about his parents lack of such, and his upbringing without. As an explanation of why his grandparents weren’t religious he writes:

“My grandmother was always too rational and too stubborn to accept anything she couldn’t see, feel, touch, or count. My grandfather, the dreamer in our family, possessed the sort of restless soul that might have found refuge in religious belief had it not been for those other characteristics–an innate rebelliousness, a complete inability to discipline his appetites, and a broad tolerance of other people’s weaknesses – that precluded him from getting to serious about anything.”

“…This combination of traits – my grandmother’s flinty rationalism, my grandfather’s joviality and incapacity to judge others or himself too strictly….”

To me, these sections could possibly hint that Obama is not exactly a deep religious believer himself. And it is possible that he, while he is a self-proclaimed Christian, could have adopted those views (truly believing or not), knowing that did he not, he would not last long in politics. Perhaps Obama has this way even adopted Christianity because he is intelligent, and not in spite of.

It is a little scary to think about though, that USA seems more religious now, than when the country was founded. And why the presidential oath, need to be taken placing a hand on the bible is in itself quite scary. The constitution states “no religious test shall ever be required as a qualification to any office or public trust”. And the “so help me god” part of the presidential oath, is not part of the original oath.

Having a self proclaimed non Christian, or even better non religious believer as president would be the real Change, which I look forward too. But unfortunately this does not seem likely somewhere in the near future. That being said I think Obama is an extremely welcome trade off.

GDSN has arrived
  icon1 Brian Zhang Larsen | icon2 Uncategorized | icon4 01 7th, 2009| icon3No Comments »

I normally don’t count Russia as a typical place for IT first movers, but in this case my prejudices proved wrong. In an earlier post I mentioned the potential of the Global Data Synchronization Network (GDSN), but at that time it wasn’t really implemented anywhere, and information on the initiative was still very scarce. But now it looks like something finally happens.

The German based Metro Group has announced that they will use the GDSN, to update their product information in Russia. In order to leverage such a network, suppliers obviously need to be in on it as well. And initially, a limited, but heavy array of suppliers has joined METRO Group in starting this initiative up, as it potentially has a lot of benefits for all involved partners. Kraft Foods, Nestle and Procter & Gamble has currently signed up for the participation in GDSN, and with these big players, its hard to imagine others won’t soon follow suit.

Metro Group has long been a front runner in testing and implementation of new technology, e.g. their RFID implementation in their Future Store in Tönisvorst Germany. Product data is currently already being synchronized via GDSN in Germany, Poland and in the U.K, and Metro Group have plans to roll out the technology here in Denmark as well.

Sorry to disappoint you Mr. Gladwell, but i just won’t do it! But good luck finding yet another new word, for yet another self invented phenomenon in the coming year.

The 10 hottest sub atomic particles of 2008
  icon1 Brian Zhang Larsen | icon2 Uncategorized | icon4 12 9th, 2008| icon3No Comments »

As the year comes to an end, the net explodes with top ten lists. But I think a very important list is missing, which is why I bring you “The 10 hottest particles of 2008″.

10. Higgs Boson
It was everybody’s hope that the LHC at CERN could prove the existence of the Higgs Boson. The LHC however, disappointed drastically and this specific Boson have yet to reveal itself.

9. Baryon
Everybody’s favourite hadron subset, way cooler than the meson. We have high hopes for this one in 2009. In 2008 the particle continued to shout “FU mesons”.

8. Chroniton
This particle is only featured in Star Trek, which as we all know is a clear projection of the future, hence true. The particle is the essence of time itself, and may be related to the more conventional Chronon. While time is not everybody’s best friend, it sure comes in handy when vacationing.

7. Bacon
Technically bacon is not a particle, at least not yet proven, but it sure tastes great.

6. Gauge boson
Its alias as the “Force carriers” says it all. I bet they will listen to you if you have a high enough level of midi-clorians in your blood cells.

5. Neutrino
It is likely that you have a neutrino in your mouth right now, but can you taste it? No, you can’t. This is the cool thing about the neutrino, it is probably the most sneaky of all our known non-hypothetical particles. You never know where you have it, as it can penetrate close to everything. Not even Maxwells demon can cage this wild beast.

4. Graviton
This hypothetical particle, hypothetically helped us keep our balance all year, providing gravity to keep our feet on the ground. The particle also showed its teeth, while it was a mediating factor in the Sichuan tragedy this year.

3. Anti-proton
Actually an anti particle, but nonetheless the anti-proton kept the hopes alive through 2008 in every antimatter-energy nerd, hoping to see anti-hydrogen powered engines blasting through space in the near future.

2. Tachyon
This hypothetical particle is going to change to world when it reveals itself. Tachyons has the ability, instantly to travel any distance, time being no factor at all. Just imagine a tachyon drive on your bicycle.

1. Photon
Yet again, the lovely photon didn’t disappoint. This particle gave us the ability use our visual sense, all trough 2008. Only at night time this particle kept it on the low down, but everybody needs to rest once in a while, even subatomic particles.
