My word - two confusing things, subby. 1 Why is this stupid? 2 Who shaves leaf sizes with a chainsaw?

A forest is not a big truck. It's a series of tubes.

Maybe submitter was aiming for [SAPPY] and missed.

I suspect their model has too many free parameters or other simplifying assumptions. "First, consider a spherical tree..."

What's a chain saw? Is it a saw specialized for cutting chains? Ah, the tricky english language.

Chainsaw.

That wasn't hard, was it?

and here I always thought trees limited the size of their leaves for ethical and religious reasons.

I find this type of physical explanation for plant structure convincing. While there are likely to be other factors involved, as a general observation using physics to describe structural limitations seems plausible.

"It's a very simple observation," says ______ ______, a biophysicist at _______ University, who presents, along with _______ _______ of the University of _________, the analysis in a paper published today in _________ ________ ________. "We were fortunate that others hadn't made it before."


Shouldn't every single story about scientific discoveries include this paragraph?

Or one very much like it. Preferably with the blanks filled in with names, and stuff.

I think tag is for how subby felt after reading the article.

Wow, I wish I'd thought of that first.

Uh, this may be stupid, but doesn't 'simple physics' limit everything? Like, that's how it works?

No. We will just keep finding more technology and colonize the universe. Like, I hear they are going to find a whole new periodic table of the elements soon with magical materials in it.

Everything summarized well in the intro. Then couldn't wrap my head around the concept of trees as tall as the length of a football field.
 
2013-01-06 09:42:38 PM  
I wonder what complex physics will limit.

Quantum Apostrophe: That wasn't hard, was it?


He used "chain saws" in the headline, so you edited it to "chain aws".
