No...because of your word "perceive".

Another question, are humans beings "affected" by anything that cannot be detected and measured? Yes, I definitely think there are things that we cannot detect or measure, but that still affect us in major ways.

I'm not just talking about things like earthquakes and unpredictable weather. I'm talking more along the lines of chaos theory generally. For example, if the parents of an incredible genius are mean to their child, how will the world be affected later, as opposed to if this incredible genius grew up in a loving household? Can we predict if the kid will grow up to be a Bill Gates or instead a Bernie Madoff? Can the affect of this child's upbringing on the world's economy be measured one way or the other? I don't think so...chaos!!!
