Aah, thanks. A couple of friends are reading this apparently romantic book as a bedtime story to eachother every night, Learn You a Haskell for Great Good! and are trying to convince me I will die a sad death if I don't know it.

So, I am ok. Nutin serious.

You have some weird friends

I think I'd rather hammer six-inch nails through my head - it'd be more fun and much less damaging to the brain

Mhahahah...I think I have faulty strange/normal friends filter set up.

Normality is for the weak I am still tempted by the book.

Re: Ask a Scientist

Damn, another nerd got to "haskell" first. Congrats. All I can say is the only thing worse to learn is the magnificently named brainfwck. Can you believe someone would call a computer language that?

Musicchick, you can impressive your geeky friends with that, if you like.

Portion control.

Just don't share. Or get another pack.

Re: Ask a Scientist

Many scientists refer to the negative consequences of global warming. Not asking to debate that (I'm sure a rise in sea level due to ice caps melting would not be good for the Netherlands). My question is, how do scientists know that global warming will NET be detrimental to earth/humanity overall? Won't it result in benefits for many countries as well (e.g. shift in climate making some parts of the world more suitable for agriculture than before)?

Re: Ask a Scientist

Is artificial intelligence that is significantly based around context one of the tricks we have been missing in this field so far?

As a fascinated amateur in computer science, I don't think so. Google already uses context to get the amazing results that we know and love.

The software techniques used by Watson are close to state-of-the-art (i.e. I recognize the buzzwords in the Wikipedia entry ), but the main difference with other competing efforts seems to be the huge hardware firepower used to get fast answers from Terabytes of data.

Re: Ask a Scientist

You must have seen lots of birds specially long leg ones! standing half of the time on power line masts and wires. They have done it now for a few generations in last a few decades of having the lines.
How dangerous is that, for their genes, cancer, impact on next generations,... due to exposure to such a strong electromagnetic field, ...!?

Re: Ask a Scientist

Three random questions...

1. I've seen pictures of bottling plants, where bottles are being filled up while they are actually moving along. What is the advantage in doing this, compared to filling the bottles while they are still? Surely the machinery involved to fill up a moving bottle must be more complex and prone to breakage than one which just fills stationary bottles...

2. I've seen odour-removing soap, which is essentially a soap-shaped block of steel. Do these things actually work, and if so how?

3. How common are artificial fragrances in food and drink? I've heard that there is a company that produces the smell that is used in McDon*lds hamburgers, so that they smell and taste exactly the same all over the world, regardless of the type and quality of beef used. I've also heard rumours about eg Nespr*sso capsules, and how they are tweaked so that the coffee they produce smells exactly the same, regardless of the water quality or hardness. How about with champagne - is the smell of that also artificially tweaked? How can a company like eg M*et produce tens of millions of nonvintage bottles per year, all smelling and tasting exactly the same as each other, and also the same as bottles from previous years?

I think the jury is out as to whether or not these really work. They are bars of stainless steel and are thought to work for garlic and onions ... maybe fish smells too. I believe the "science" behind this is the following: Sulfur from the onion/garlic/fish would be attracted to and bind with one or more of the metals in stainless steel. If the sulfur compounds bind to the steel, then the odor is removed from your fingers.

If you re-read your own questions, you will find you answered it yourself

I'd say these strong electromagnetic fields are pretty safe

......... unless of course the legs of the birds have selectively stretched over the last few generations to distance themselves from cancer producing electromagnetic forces.

Surely the machinery involved to fill up a moving bottle must be more complex and prone to breakage than one which just fills stationary bottles...
The reason it is done this way is so that the bottles themselves - i.e. the parts most prone to breakage - are kept in motion at a constant speed. This removes the need to slow them down to a dead-stop, fill them, then accelerate the now-full bottles them back up to speed with the inherent risks of breakages.

Keeping them on the move also improves the productivity of the plant, due to the higher average speed of the bottles as they transit the plant, as compared to a where one stops then restarts them.

Re: Ask a Scientist

Electromagnetic fields are only (i.e. might possibly be) harmful when the wavelength of the generated signal is smaller than the body size of the animal/human.

The powerlines in Europe have a frequency of 50 Hz, which makes the wavelength 5995.85 km, which seems not to be in any order smaller than the body size of a long legged bird

Apart from this, like with the health effects from cell phone systems, the scientific research according this topic has not really given a solid statement.
But you can clearly link the results of such research to the party that sponsors the research.
