I recently read somewhere that spiders like places to hide. Wood piles, clotes, basement, dark cracks and crevices. Well, yesterday there was a spider and a big long circle shaped web - going from my kitched table to my refridgerator, and the spiders just sitting there, out in the open. There is no where to hide where he was, it was just right out of the blue in the middle of the room where my fridge and my table is, rofl. He had a big butt. Why did he decide to make his web there, out in the open? Does anyone know? He's more prone to attacks, because my dad killed him.. xD

I am an amateur birder. Over the last decade or so, I have heard of more than 15 new species in NA, only one of which might have been newly discovered. The rest were split off from some existing species on grounds that sometime seemed arcane or subjective (such as "less than 20% of the respective populations interbreed")

it only takes about 2/3's (about 67%) as long. i'd expect a lower amount of time but closer to the 85-90% range. So my question is not why is there in increase, but why such a drastic one.

..
A lone Amateur is said to have Built the Successful 'Ark'.

Whereas, A Large Group of Amazing Professionals Built the Ill-fated 'Titanic'.

How can we explain these phenomena?

"Titanic' proved that 'a ship in harbor is safe but that's not what ships are for.'

Any such Individual feats & group failures?

Just wondering!

Why does a mirror invert left and right but not top and bottom?
i mean, it doesn't know that it should only invert left to right and not the other.......... so you got an explanation?

I would think it is plantar fascitis or a spur, but it does not hurt when I walk.
What could it be?
