These are my favorite colors. My favorite time of day is balmy
My favorite physical phenomenon is dispersion. Rarely is the true
nature of light apparent in our domain; that it is physical, that it
is married to oscillations.
Most people don't know it yet, but noninvasive neurotechnology is
possible within 10 years, and will be the most important thing that
happens in our lifetimes.
The human brain is powerful and flexible.
Individual differences are all noise in light of our astounding
biological ability to learn. We can learn to play the oboe, a
fantastically obscure map between glottal motions and sound
output. We can learn to echolocate. Provided the right feedback,
humans can learn to increase firing of a single, arbitrarily
whose infrastructure is rarely exploited by our interfaces.
We haven't nearly reached the boundary of neurotechnologies
permitted by physics.
With kHz-switching micromirrors, we can adaptively beamform light
to focus it through the skull. If we can measure the arrival times
of photons through the head, we can construct a map of neural
activity. The electronics for sub-nanosecond measurements are
available in iPhones and can be made for $7 a pop.
These are engineering challenges: difficult, but physical
nonetheless. And while engineering marches ever forward, AI is
lowering the bar for what can be made into powerful
Increasing communication between people is one of the most
beautiful things you could do.
Beyond that, being alive and conscious is just wonderful.
Why do snowflakes clump together? Can the correlation time of a light
in the distance tell you about your location relative to it?
