How annoying. Definitely works for me as they say.

It's a 2007 chapter from an introduction to psychology, the first
sensible link that came up via a DuckDuckGo search. There are a variety
of other places to look. Here's another.

It's a 1956 paper by Miller that claims 7 is the magic number for short
term memory, the number of chunks of stuff you can keep for a certain
period. A chunk is not a defined thing such as characters or words, but
they are examples.  I am not sure what the experimental status is of
this "theory", but I suspect no-one has disproved it as yet.
