By worlds largest number(s), I mean the largest number(s) that have ever been used in mathematical proofs (which is the accepted definition). Try to make these generally unfathomable numbers understandable.

10 points for best description (using infinity is not allowed).

Which animal is faster: the frog or the toad?

My friend and I have been discussing this for a while, and we really would like to know. A lot of people assume the frog is faster, but is it true? I'm sure there are specific frogs are faster than specific toads and vice-versa, but in general, which one is faster?

The difference between using one 555 timer and a 556 timer for PWM control?

I have seen different site using 556 set up as one timer in astable
controlling a second timer in monostable mode. Other sites show PWM by
using only one 555 timer set up in astable mode. I would really rather
use only one 555 timer, but what is the upside to using a setup with a
556 timer?

What question are you most tired of in the math and science category?

My personal least favorites are:
1. Do you believe in evolution? or some variation like Did we come from monkeys?
2. Is Mars coming close to the Earth on August 3rd?
3. Did we really land on the moon?
4. Is the Universe expanding? What is it expanding into?

I mean I'm just making a joke here and I'm all for answering peoples questions and the free exchange of information and all that but it would be nice to hear so new questions and not the same ones over and over, you know?

How can people deny the existence of evolution?

Look at the Galapagos finches, the birds that Darwin was inspired by. We can see how they've EVOLVED and adapted to their environment within the past 20 or so years. Other birds are coming in that eat large seeds. The finches can't eat those large seeds anymore, so they've developed smaller beaks so they can eat smaller seeds. Yet people still deny that evolution exists, even though the evidence is right under their noses. How ignorant and stupid can people be?

Are there any ICs (Not PICs or other ICs that require programming) that allow for a simple Servo Motor Control

I was originally going to control a "regular" DC Motor by using a PWM circuit using a 556 timer. The part count was large and I came across some other issues that could be solved using a Servo. I dont have a PIC programmer or anything like that. Do you know of any ICs that can rotate the servo without many external components?

About space.?

I guess Pluto isn't going to be a planet for much longer, but it has a moon. Are there other objects in the Solar System that have moons but aren't planets? Would they still be called moons?
