### Ironic Observation

Well, I guess it's more an observation of irony. We are rapidly approaching ספר במדבר which is known as the book of Numbers. And for good reason. But it is interesting to note that we find numbers and counting as a recurring theme in the פרשיות leading up to במדבר. First, we cover ספירת העומר in אמור. Actually, we already began dealing with counting at the end of מצורע with the הלכות of זב and זבה. Then, בהר begins with the counting for שמיטה and יובל. The ensuing הלכות all involve calculations based on the proximity to יובל. We end of ספר ויקרא discussing the laws of ערכין which involve considerable calculation as well as a brief mention of מעשר which also involves numbers.

### Omer Counting in Different Bases

My father-in-law showed me a ספר that discusses whether or not you can fulfill your obligation to count the עומר using other base systems besides decimal. This a good case where the question is far more interesting than the answer. Surely, one should not do that. However, it was a very interesting concept I had never thought of before. So, I added a widget on the blog's sidebar which will display the day of the Omer in various relevant bases.

On the insistence of reader Pi (that's his shorter name), I have added base 7 as well as a pick-your-own-base section.
Here is the excerpt from the ספר.
