  • Rotating an apple was easy.

    Then I tried putting a face on it. That didn’t work.

    On a whim I searched for an image of an apple with a face on it, found one, and found it easy to rotate that imaginary apple and face.

    I can imagine drawing a face on an apple, but find it harder to keep it in my brain if I rotate it.

    I wonder if the brain has an easier time taking a “snapshot” of something you’ve taken in from eyesight and manipulating it rather than generating an internal image from scratch and holding that image while working with it.



  • Materials science and the ability to harness adequate energy to drive such a machine. IOW, lighter, stronger metals, durable metals, bearings, lubricants, tire materials, quality fuels, engine power which is dependent on all the aforementioned, and all of that tied to close tolerance mass manufacturing.

    We really take for granted how fast and precise manufacturing has become.

    Even simple things we don’t think of. For instance - Cars from the ‘80s and before had interior materials that sustained UV damage and you’d end up a with fading, cracked dash, cracking seats, etc. Windshields would crack super easy from a rock chip. Now? The vast majority of car interiors remain in very good condition other than usage wear. I’ve taken multiple rock hits on windshields with many different cars and had zero cracks.

    Materials science is amazing.




  • There’s not much worse as a kid in a learning environment, or even with your parent(s), to be shut down painfully for being right about something that they don’t know or don’t think you know. Really crushes the satisfaction of nailing a win and turns it into bitterness and starts the lifelong process of keeping your mouth shut when you’re right and letting others win when wrong.
