» What cellphone do you have?  ...  Last Reply: 1 year ago by stereoroid.

I have two cellphones at the moment.
One is a Siemens ME45 (black and orange) and the other is a Motorola V980

I have these basically because I can't afford any of the newer, nicer phones.

But, I like the Siemens because it's small and tough. It's my all-terrain phone. And the other one is a simple clamshell that has 3G so I can go online and test wap sites, etc.

» The Mysterious Vanishing Bees  ...  Last Reply: 1 year ago by hthth.

I suppose that they just die far away. I mean, they don't necessarily have to fly in big clumps and all die in the same spot.

They could be looking for pollen elsewhere and end up dying.

You could very well stick a couple thousand or million in a park and not even notice them if they were well dispersed. And then there are animals that eat them.

So I don't see the body count as a major problem. It's more the fact that the bee hives are empty and thus the biosphere is feeling their absence.

Oh and by the way, there are normal fluctuations of bees similar to this on a periodic basis, but not just such high percentages. And then there is the economic problem this raises. No honey, makes no money, so to speak.

» The Mysterious Vanishing Bees  ...  Last Reply: 1 year ago by hthth.

@siamlinio: I don't believe that one bee could even serve for anything. You need more than one sample to reach any sort of conclusion. If you had a couple dozen dead bees, then you'd have something else in our hands.

And regarding this bizarre situation, my bet goes for new pesticides. But I still have to look into the latest papers.

» Hiding from the fire? Guess what's coming at you!  ...  Last Reply: 1 year ago by rick.

@shadowsun7: Yes, that was my main argument.
Well, I approached the problem by asking the teacher for more details regarding the fire, since the question didn't explain anything about it.
He then explained he imagined it would be a ring of fire and the hole would be shallow.

I then told him that it was not explained where the fire was coming from, how tall the flames where, how deep the hole was, and therefore the question could have different answers.

And having explained my particular imagined view of the question (see image above), he agreed to my logic and had to consider my answer correct.

Quoting the famed Parker Lewis: "Coolness!"

» Hiding from the fire? Guess what's coming at you!  ...  Last Reply: 1 year ago by rick.

Well, I got it right and explained that the question wasn't specific enough, so he said it was right depending on the circumstances. :) Coolness.

» Hiding from the fire? Guess what's coming at you!  ...  Last Reply: 1 year ago by rick.

The thing is he states that radiation isn't altered at all. I happen to disagree because if the man is hiding in the hole, he will have a certain amount of radiation not hit him directly, therefore minimizing (as much as possible) the radiative heat transfer.

So, all 3 components should be minimized to a certain degree. Thus also depending on the details regarding the hole, the size of the flames, etc.

I'm going to argue with my professor once again tomorrow. Because if I can get him to see that the question is not explicit enough, then he'll have to reformulate the question.

» Hiding from the fire? Guess what's coming at you!  ...  Last Reply: 1 year ago by rick.

Sorry, that's my quick Portuguese->English translation :)

Yes, the question is very incomplete and if I am in the hole, at least some of the radiation is minimized, right?

» Hiding from the fire? Guess what's coming at you!  ...  Last Reply: 1 year ago by rick.

I find that "minimized or eliminated" is the key here. Therefore, option B would be the best option because in fact the man is protected from all three components because basically he is in fact protected from the heat.

Seems plain and simple.

Thanks for the extra option. I was hoping to keep it within the selected options :)

Hiding from the fire? Guess what's coming at you!

Science Community — Posted: May. 2, 2007  ...   Last By: rick @ 1 year ago

I've got into a lively discussion with a professor of mine regarding a question he put on an exam we did some time back.
The subject at hand is Transfer Phenomena and the question is directly related to Heat Transfer and the 3 main concepts involved. Conduction, Convection and Radiation.

Well, the question goes like so:
-------------------
Imagine you are in a forest and a big fire appears out of nowhere. There are big flames and you decide to hide yourself in a hole nearby. The heat transfer from the fire towards you is now:

A. Minimized or eliminated regarding radioactive and convective heat transfer but not conductive.
B. Minimized or eliminated regarding radioactive and convective and conductive heat transfer.
C. Minimized or eliminated regarding conductive and convective heat transfer but not radioactive.
D. Minimized or eliminated regarding conductive and radioactive heat transfer but not convective.
-------------------
My professor says the right answer is C, but I must insist that it could only be B, since the simple fact that he is in the hole minimizes all three components of heat transfer.

And because I wanted to better illustrate the situation to him, I drew up this quick example of how these 3 components present themselves:

I'm not sure anyone here know about this type of stuff, but I'd like some opinions, hopefully something I could confront my professor with... So, any thermodynamics buffs around?

@nowickedwitch:
I happened to find my first creationist that doesn't believe in Evolution and happens to believe that everything is God's work. And above all, she's a university student getting a degree in Biology! I even wrote a post about this.

Hey, it wasn't my intention to be impolite. It's just my point of view.
I happen to study in the life sciences area and the evidence is just to overwhelming to be denied.

I live in Portugal, and although the stats look in favor of the belief of evolution, I'm sure that the majority of Portuguese people would swear by the Bible. Portugal is a very roman catholic country, so it'd be further down on that graph, imho.

This chart isn't new. And it's been pretty well analyzed and debated over the last year.
There is a more in depth analysis of this chart and what's behind it over here.

I personally think that the Theory of Evolution has too much evidence towards it to be denied.

» Earth-like Planet Discovered  ...  Last Reply: 1 year ago by rick.

Yes, but it's like watching football and listening to the game on the radio. There's a bit of lag, but you are sure it's happening more or less "now".
But when we talk about lightyears away, we could actually be looking at a planet that's not there anymore, or way more different than we see it to be now.

If you want, imagine there are aliens or people or ewoks on that planet. And they were looking at us this instant, they would most probably be looking at our cavemen or the renaissance man, or something like that from our past. Because the light took that long to get there.

» Earth-like Planet Discovered  ...  Last Reply: 1 year ago by rick.

And I'm going to bring this back on topic just for the fun of it.

20 lightyear = 1.89210568 × 10^14 kilometers

If you actually think about the speed of light traveling across space, this means that we are not looking at the planet in "real time". I mean, the image we are seeing traveled all those kilometers to get here so we can even see it.

Think about our star, the sun. If it went out now, we'd still have about 8 minutes of light before we even noticed it. Consider this sort of what WoW players know as LAG ;)

So, for all we know, we could be preparing a mission to this planet some time in the future and when we finally get there, it's burnt out, or dry, or blasted in bits by asteroids.

Well, that was just a bit of food for though. And an attempt to put this one back on track.

Sort of like Wolverine, right? ;) Except that he also has the adamantium skeleton going for him too...

» What's your transgenic function of choice?  ...  Last Reply: 1 year ago by Kamigoroshi.

Errr....I cannot answer this because it goes against my understanding of transgenic and recombinant genes. If it was that easy to incorporate it, it would already have been done.

Hey Kamigoroshi, I'm a biotech engineering student and I also understand that this is yet not possible. And most of these opinions will most probably never be possible (I'd actually say, never).

But just for the sake of conversation, if you could pop a gene into your genome that could give you a natural living organism's skill or special function, what would that be? ;)

» The Biggest Scientific Developments  ...  Last Reply: 1 year ago by craig552uk.

My #1 choice would certainly be the Double Helix (nice one Kamigoroshi).

But other scientific discoveries come to mind and deserve some attention would probably be Vaccines and Antibiotics.

What's your transgenic function of choice?

Science Community — Posted: Apr. 25, 2007  ...   Last By: Kamigoroshi @ 1 year ago

Every day there are new stories of transgenic experiments where a foreign gene is introduced into another living organism so as to reproduce or improve the function of the gene in the original species.

For example, we've all seen the glowing pigs that got the fluorescence gene, or plants that can also glow fluorescent when disturbed.

So my question is:
If you could pick a function that is present in animals or plants and have it genetically introduced into you so that you could possess that function, what would it be?

This is obviously hypothetical, but try to keep it believable. Let's not just say "I want wings!"

I'll start it off by saying I'd like the genes that make it possible for salamanders to regrow their limbs and tail when removed. Similarly this also happens in sea sponges. (no, I don't want to be sponge bob!)

Here's a good blog post that shows some of the possible reasons for the bee disappearances.

It's honey and syrup along with many fruits, veggies and nuts.

... and cows and goats and chickens ... and burgers and mcnuggets and milkshakes ...

hrm... i'm hungry :D

» The Mysterious Vanishing Bees  ...  Last Reply: 1 year ago by hthth.

It's all funny and such, but bee's are really important in so many different ways.
But if you don't believe in me, take it from Mr. Albert Einstein himself that once said:
"If the bee disappeared off the surface of the globe, then man would only have four years left of life. No more bees, no more pollination, no more plants, no more animals, no more man."

So basically: we. are. doomed.

Is Coda the DW killer?

Apple Community — Posted: Apr. 23, 2007  ...   Last By: alexsuraci @ 1 year ago

Although I'm not a mac user, I've been watching the twittering about the new Coda app by Panic.
For those that are mac users and maybe also DW users, do you think that Coda will be that much of an upgrade to purchase it?
It looks sleek, but I'm not sure there's anything REALLY great about it, except for the fact it's made by Panic. :)

What you guys think about this? Hype or really good app?

I wonder how effective that math really is on combination locks. Some questions come to mind regarding why divide by 4? Why add 2, why is the first number found, the last one of the combination?

Cool nonetheless. But 100 tries is still fairly time consuming.

» Would you like a sheep's kidney?  ...  Last Reply: 1 year ago by Darice.

Yes, I know. It's not even being sick. You can be gone in a blink of an eye. So if you want to be a donor, go register as one.

I was a victim of a hit and run in 1996 that left me in pretty bad shape. Broke my leg, my head and got really really bad cuts from the windshield. I luckily made it and am fine today. But out of the blue, at the age of 16, I could have been a gonner. So, being an organ donor is without a doubt a decision to be made asap. :)

Hope you get that kidney soonish. I wish you the best
