Destin Sandlin examines the systemic engineering and economic hurdles involved in manufacturing a grill scrubber entirely in America. Through a deep dive into sourcing components like injection-molded knobs and specialized chain mail, the project highlights the complexities of maintaining domestic supply chains and preserving vital technical trade skills in a competitive global market.

Our fucking eyes are built backwards!

But at the same time I can still get a better view of Mars in my telescope with my eyes than I can with a $2000 camera. Crazy how flexible our eyes are

    To those who don't know. This person is 100 percent correct.

    The retina in the back of the eye. The part that registers light and lets us see , is wired backwards.

    Essentially the nerve fibers that connect to the retina comes out in front of it. And blood vessels are also in front of the retina.

    So when light enters the pupil ,it also has to pass through nerve bundles and blood vessels to reach the retina.

    Making our vision a much lower resolution. In comparison to if photons could make more perfect unobstructed paths to the retina. This design also causes humans to have a blind spot because all those nerves and blood vessels have to exit the eye through a tunnel where no retina cells are. Not that light could penetrate that bundle anyway.

    If you want to understand better what I mean, we can compare a human eye to that of a cephalopod, who actually has a better designed eye that's not made ass-backwards.

    I highlighted the nerve fibers in pink so you can see what I mean.

    This is a product of evolution. A long time ago, our ancestors were fish.
