I've always seen it referred to as Hungarian notation, but...
Hungarian notation is just adding " descriptive" prefixes, like
pszSomeCharArray ,
Polish notation is like driving on the left (wrong side of the road, Howard!) by default.... It inverses L-R because it is easier to parse (not! sheer laziness at Palo Alto). I would recommend
Forth for a powerful demonstration of that.
(I can actually still program in Forth
and do so when I want to get a headache on purpose)
[edit]
There you go: free computer science history lesson... Palo Alto is not in Poland and Poland as a country is not in the U.S.A:, Hungary may be in(or temporarily confused with) the U.S.A. because of similar ignorance in government: the math behind it is invented by Lukasiewisz

https://en.wikipedia.org/wiki/Hungarian_notationAll those silly knowledge is not to exclude you from being a good programmer, but it is when discussing grammars.
Note that in the Netherlands, Polish people run a higher risk of causing an accident as a percentage of the total population. This is not caused by driving at the wrong side of the road perse, but by intoxication. (fact!)
Important note:
If you want to write a working compiler, start with Polish notation: much, much easier to get it right, but you need to be a bit off to program your own language...Forth should have been called Daft)
