In some lectures people try to explain the difference between a two dimensional universe vs. a three dimensional one but using the example of a shadow cast by a three dimensional object. It’s a good model, we can all understand that the shadow is two dimensional and reflects something three dimensional. Then, often they proceed to try explaining a four dimensional world might be casting a “shadow” that’s three D. They lose me there though I’m trying to follow, though it sort of makes sense but also sort of breaks me apart and feels unnatural and difficult and exhilarating. I’m working on this thing in Bflat. Colouring easily with my right hand, it’s so easy and normal for my right hand to feel like it’s leading or arranging but there’s a different experience to challenge it. A lot of the effort now is in trying to make the left hand solo, be the boss. It also breaks my brain apart in a similar way and feels like focussing on the left hand as leader is unnatural and difficult and exhilarating. I think what’s so similar between these experiences is that we are sort of charged up, like magnets to be oriented in one way and to try reorienting your own charge will never result in sustaining the new orbit but the effort is the reward in itself.
