My theory is that actually our eyes are faulty and the blurred state is actually our default state of the eye.

The default state for me seems to be seeing distant objects sharp.

Our lens only changes focus and nothing else.

I don't understand what you said

In general

Let's start with the function of the lens in our eye. You can only focus (see sharp) on one distance at a time. If you focus on an object close to you, you see everything at a distance blurry (you will also see objects blurry which are even closer ). When focussing at the distance, you relax the lens of your eye, changing its shape. You will see objects at a that distance sharp and closer objects blurry.

You'll have to be more specific.

Then you are seeing blurred in that section.

Which is a passive effect i.e. I'm not actively blurring my vision. But as I already said, I can actively blur my vision for close objects. I can also focus on something close, which passively blurs objects in the distance. What I cannot do is actively blur objects in the distance (ie without "cheating" by focussing on a nearby object).

Put something close up to your eye when you do that... is it sharp?

Of course not.

My guess is that it is useful to defocus visually when you want to focus mentally on the periphery of your vision, possibly in one area of the periphery or possibly for the appearance of something, say when hunting or even fighting). I really have nothing to back that up other than to say I feel it works for me (not that I hunt or fight, but in a number of similar ways). It is a related technique to "glancing around" but I (feel again) it has advantages in some circumstances, and sometimes switching back and forth between the two techniques. I'm not sure everyone doesn't do this whether they realize it or not.

When I focus on my peripheral vision, eg in pattern finding games, there is no blurring. Wouldn't that also blur the periphery? 

I can only do it when looking at a nearby object. When I look in the distance, I can't blur my vision. 

Your modules would also need to be pretty large to avoid too large a difference between your head and your feet.

Real logic gates cannot yield perfect square waves and introduce harmonics of their own.

If you want a pure sine, go analogue ;).

If you believe in god, then things must have a purpose.  Otherwise things are the way they are due to the laws of physics.

If that premise is true, than god cannot exist

Are such materials as concrete, asphalt, sand, stone diamagnetics or paramagnetics?

It depends on the minerals inside the concrete, asphalt, sand and stone. Some, such as magnetite, is even ferromagnetic.

That makes no difference. They can cancel each other out when parallel as well. Angular momentum doesn't have a position, only an orientation.

I can help you out in that respect, since it is quite simple:

L-L=0

With L the angular momentum. Both angular momentums cancel each other out, and the resulting angular momentum is zero. Without angular momentum, no gyroscopic effect.
