Most
of the websites that mention this day are pretty cutesy with the
write-ups...with lots of repetition like this:
It's
National Repeat Day!
It's
National Repeat Day!
And
the suggested “celebrations” seem sort of...umm...un-fun. Like I
read this suggestion: when you put your socks on, this morning, take
them off and then put them on again.
Really?
That's how we want to use National Repeat Day? To make more
work for ourselves with no added benefit?
How
about this, instead:
The
power of repetition

Robert Collier once said:
In
the classic movie Groundhog Day, Bill Murray learns that it
isn't enough just to repeat a day...you have to try doing different
things while repeating the day. You have to learn from what works – and what doesn't work.
When
writing computer programs, you soon learn the power of
repetition, or rather recursion.

| Recursion is when a computer routine calls upon itself. It's like a picture of a guy painting a picture of that same guy painting a picture of that same guy painting a picture... |
 |
| You can explore recursion yourself by taking a recursive self portrait where two mirrors face one another! |
When
investigating fractals, again, there is amazing power of
repetition. One way to start an investigation of fractals is to
investigate a stalk of broccoli. Tear it down to smaller and smaller
pieces – and each piece looks a lot like the whole!
You can also doodle fractals like Vi Hart.
Someone made a video about making a video about how Vi
Hart makes a video! A recursive video!
Repetition through recursion in computer graphics can turn a simple line of code that tells the computer to draw a circle into something utterly magnificent:
