Today
is supposed to be a day to build our self-esteem. A day to look in
the mirror and—whether we are young and old, male or female, sick
or healthy—assure ourselves, “You look fabulous!”
So,
go do that, and then come back!
I'd
rather actually compliment our mirrors, rather than ourselves! Our
mirrors do a great job of reflecting things for our benefit—and
there are a lot of different sorts of mirrors used for all sorts of
different tasks, too!
There
are tiny mirrors used by dentists and dental hygienists to see the
back sides of our teeth.
We
have fun-house mirrors that make us look all wiggly, and kaleidoscope
mirrors that give us beautiful patterns.
We
have one-way mirrors that enable, for example, police to watch
suspects in an interrogation room while the suspects cannot see them.
There
are lots of other uses for mirrors, as well—everything from
military uses to emergency signaling uses, uses in everything from
seasonal lighting and “green” skylights to TVs and cameras.
What
did people use as mirrors way-back-when?
Glass
mirrors with metal backing date back to the first century C.E. or
earlier. However, for a good long while only rich people were able to afford good
metal-backed glass mirrors. (The silvered-glass mirrors we use today
was invented by Justus von Liebig in 1835.)
People
also sought their reflections in highly polished metal or obsidian
mirrors—and, of course, in very still water.
Celebrate mirrors!
- Try to print your name so that it looks right in a mirror. Even harder--try to write your name in cursive so that it looks right in a mirror!
- Here is a science “game” that can help you learn about angles of reflection.
- This PDF offers a lot of mirror activities!
- Last but certainly not least, create your own kaleidoscope!
