ok since we have cloning for animals, why don't scientists clone the food we eat, for an example, a box of mini wheats before it hits shelves, in the factory we clone the entire factory full of mini wheats then give it too the stores, we keep giving the stores cloned food so we can keep a endless supply.

we sort of do this already. Ever notice how bananas don't have any seeds? Well how do bananas without seeds reproduce if they don't have seeds? The answer is we clone em'. We cut off a little bit of a banana tree, and like plant it in some stuff to like make it grow into a new tree man. Every banana tree is like practically identical.

There is a probability that you are as you are. It's small but it exists. Call this P(you). The expected amount of you's to exist is the amount of events multiplied by the P(you).

In an infinite universe with an infinite amount of stuff which is clustered in a way that's similar to our local region and the stuff obeys the same rules of physics as our own. Let each cluster of stuff be an event with the possibility of you existing then doing crude math you can see that:

So I was exploring a superfund site today with some friends. I won't specify which specifically but I'll say that it's one of hundreds in Western NY, (USA). We came across this pit full of an almost glowing blue liquid. The white powdery looking buildup along the bottom makes me conclude that perhaps it's acidic? I was t going to touch and find out. Can anyone here shed light on what I'm looking at? Nothing came up when I tried to research it. Any insight would be greatly appreciated.

It's a hypothesis more than a conclusion which is why I also threw the word "perhaps" in there. Salicylic acid reacts with organic material that way that's how I came up with it. Then again sulfuric acid turns sugar black so I suppose I can see why it's not a great hypothesis. I'm not a chemist and didn't claim to be. I simply asked if anyone qualified coils identify this liquid/occurrence.

If there's only one channel for the air to flow, they would both accomplish the same thing. You're not creating a vacuum when you turn a fan outside; an equivalent amount of air is coming into the room.

Better to aim it along a wall to get air circulating. It'll create a current that moves air in and out of the room.

Yes. I don't know why it happens, but it's pretty clear to me if you just look at the types of people who tend to be strong, or rather, more masculine. Something about being very masculine precludes you from developing intellectually. I suspect it's because instinctual drives are stronger in more masculine men, and so they cannot override them as easily as some of us here can.

33 KB,
does anyone have any ideas about ways to count the number of ways an n x m grid of squares could be dissected into (1x1), (1x2), & (2x2) rectangular tiles?

I was considering trying a computer program to model it, but I'm not even sure how to start.

This is a question that comes into my head a lot when I'm in my bathroom, looking down at the pattern of tiles on the floor. (it's called a variegated pattern apparently.)

For easier version: just use (1x1) and (2x1) tiles.
33 replies and 4 images submitted. Click here to view.
>>
for starters, I know that if the total area consists of A = n x m places, the number of patterns must be less than A^A / A!,
based on the idea of there being up to A 'belongingship' categories, with each tile being one of those at random.
this does not yet restrict a category to be constrained to including only cells next to each other, or to having certain shapes.
>>
you could probably also make graphs that connect every configuration by operations that either:
> connect two adjacent 1x1 squares into a 2x1
> split a 2x1 into two 1x1 squares
> connect two long-edge adjacent 2x1 tiles into a 2x2 tile
> split a 2x2 into two 2x1 tiles (two ways to do this)

then you maybe could analyze the topology of that graph - there would be a structure based on values that tell you a) the number of 2x1 tiles b) the number of 2x2 tiles

I agree, I think they'd be doing a lot of geology and chemistry, as well as set up some seismometers. I think something else they should experiment with is biology, like testing how microbes act in the low gravity and low pressure environment. I have a feeling that because the intensity of the sun is less, the photosynthetic process may be effected. Maybe since it's less energy, plants wont produce as much sugar as we expect and this could cause trouble for civilization there. They should also experiment...

Looking for fossils would be the best/coolest/optimal thing human would do on mars better than robots imo. A matter of rock manipulation and visual recognition in situ than no explorer would do on its own.

Why do Americans shit where they eat?

What benefit is there to consistently dousing your lawn with chemicals for the soul purpose of aesthetics?

related: two of my neighbors across the street just had their lawns sprayed for weeds. Guy in huge truck pulls up with a huge tank and just starts spraying the lawn. I could smell it all the way into my yard.

Is there any specific scientific research to show how harmful weed control is to both the environment and human health?

Most often because home owner's association requires it.

Lawns are pretty bad though:

The U.S. Center for Disease Control and Prevention (CDC), in a study of 9,282 people nationwide, found pesticides in 100% of the people who had both blood and urine tested. The average person carried 13 of 23 pesticides tested. - See more at: http://learn.eartheasy.com/2009/01/lawn-care-chemicals-how-toxic-are-they/#sthash.pWfDyNZu.dpuf

Why are they still allowing the use of these practices then?

Why wouldn't we want pesticides in our blood and urine? I for one don't want any pests trying to crawl into my urethra, so I actively ingest pesticide on a daily basis.
