The default state for me seems to be seeing distant objects sharp. Our lens only changes focus and nothing else.

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.

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).

Of course 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 that premise is true, than god cannot exist

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.
