I live in southern california and it rained today which brought out a ton of silverfish looking insects. However, they are not silverfish nor are they centipedes. These move slow and kind of have a curl to them...They are black and seem to have a little shell for a torso and also jump when contact with water. Not fleas either, these are much bigger about a 1/4-1/2 inch. Maybe a cross between a huge flea and silverfish...Thanks

I was looking at those floating round beds or whatever you call them, & I was thinking about getting them someday. There is one problem though, I am not good at diameters. Which one would a 6th foot tall person like better: A 4, 7, or 8 diameter bed. Actually I have forgotten so would a 5 diameter bed be 5 feet across all ways? I'm not a hundred percent sure.

Some guy ( I can't recall who ) wants to build a massive telescope kind of thing, in some gigantic crater or something. It's supposed to be able to see into the atmospheres, etc of distant planets... has anyone heard of this? And is this even possible from an engineering point of view?

Also do you know the name of the guy who wanted to do this?

hi, I'm really having trouble making sketches of planes. I know how to graph an equation of a plane with 2 variables in R^3. ex. y = x , I draw the line y = x and then that line repeats itself vertically throughout the z axis. but how do you graph equations of planes with 3 variables?

ex. x + 2y + z = 2? thanks
