Sir David Brewster was born today in 1781 in Scotland. He was very clever and made strides in the Sciences. Sciences use numbers to establish something, so Rhinos are mostly out of that loop. We applaud, but have minimal concrete input.
Yes. What Sir David did (that We can embrace) was to invent the Kaleidoscope. You look in the little hole, and there are patterns that change if you shake it or twist it or point it somewhere else.
Obviously Sir David was a fellow who provided many Happy Birthdays over the years. We say Happy Birthday back, and thank you.
