I wonder if light ever acts like a liquid. I mean, if it has elements of both waves and particles, and if we generally learn about light using water as an example, what if other qualities cross over? Like surface tension and wicking. How cool would it be to discover that light passes more easily through something that already has a light trail established? Or to find that the reason light bends around planets and stars and whole galaxies of them is because light sticks to light? I wish I were smart enough to look into it, but more than that, I expect that anyone smart enough would simply scoff at the thought.
Are deaf people who are fluent in sign languages better at understanding three dimensional concepts? Because the grammar and movements of their speech should provide an appropriate scaffold for that understanding. Signs kept closer and others kept farther or lower are altered in meaning and connotation. This connection, this bond between physical space and idea making seems like it would be an ideal garden for growing the ability to visualize. Sculpting, architecture, or even a facility with understanding the ballistics of firearms should be easier… shouldn’t it?
