Personally, I think the whole global warming issue has gotten way out of hand. Everyone says that global warming is the fault of humans and that we are going to melt the icecaps and everything.

1.) I bet if humans were really the cause of global warming to the extent that many people have believed, the ice caps would have melted years ago.

2) Recorded history has been around for thousands of years, but the earth has been around for MILLIONS. I don't feel you can make a fair judgement of the earth's temperatures without knowing how the earth has changed over those millions of years we don't know about. We might just be still warming up from the last ice age. This could of all happened before, but we don't know about and therfore could stop like it must've before.

I just don't feel like global warming is such the big deal everyone makes it and i definately don't think it's the end of the world.


Please say I'm not the only one who feels this way

Hopefully any of u know about filter design cuz I'm really stuck ...I'm trying to design a filter in circuits following the above specs in my question.The purpose is to minimize noise while providing low ouput impedence to recording device. I know I need to have attenuation of -40dB/decade by 60 Hz, but I dont know how to do it ...what R and C to use, how to align them, etc. Right now all i have is a simple low pass RC filter with transfer function(1/sqrt(1 +(wRC)^2)), but i'm getting a -20dB/decade and the rolloff isn't fast enough to reduce the input by 100 at 60Hz. Any help appreciated

say I have a wallet that contains either a $2 bill or a $20 bill ( with equal likelihood), but I don't know which one. I add a $2 bill. Later, I reach into my wallet( without looking) and remove a bill. It's a $2 bill. There's one bill remaining in the wallet. what are the chances that it's a $2 bill?
