All my life I've been horrible at Math and during college I always avoided taking Math courses. To this day (I'm 24) I am terrible at Math and I've come to the conclusion that there is no hope for me, even with a tutor. I excel in all my other courses, but Math is like a nightmare for me.

Seriously! Why? No other animals have butt cracks! And it seems to just get in the way, forcing us to wipe the remainder of our waste away.

Also, is it safe to assume that the the self awareness and physical ability needed to wipe ones own bum came BEFORE the evolution of the butt crack? I mean, if the butt crack came first, the early humans would smell poorly, and probably never reproduce, because everyone is disgusting.

Are there any other animals with butt cracks?

And here's the important question. Why did I wake up at four in the morning this morning wondering about the evolution of butt cracks?

Whether light consists of matter or not, where does it get the energy to travel at such a high speed of 300000000 m/s? If light consists of matter, then it must need infinite amount of energy to travel at such a high speed? Anything massless can travel at such a speed. And another thing: electromagnetic radiation is made of what precisely. if it exists, it must be made of something. of what precisely?

I am only interested in knowing its specific name, I was told previously that it is some kind of wolf spider but that isnt specific enough for me to find out exactly what it is called, so if you can point me in the right direction I would be happy!

Check out the picture here...

What is the rule of thumb on the minimum distance from the edge you can drill a hole without losing strength on that edge? Is it proportional to the size of the hole? Any information would be great. Thanks for your time.

if light energy exists when we switch on a torch, does it mean we can create light? does it also mean that light consists of matter from which it has been formed from the battery of the torch? Explain in detail
