Prime Number Digit Frequencies
Today I became curious about the relative frequencies of the digits that appear in prime numbers (in base 10).
Naturally, I wrote a little program to show the answer - digit-freq2:
How Many Primes Are In A Slice Of Pi?
Questions:
- What is the number of primes per n-slice of the decimal part of pi?
- What does the graph look like?
- Are there many overlapping primes (i.e. start at the same position in the slice)?
Making Chernoff Faces with Perl
Today being a Saturday, I decided to noodle around with the GD::Simple module and constructed rudimentary Chernoff faces - Cartoon data visualization.
Linguistic Analysis of the State of the Union Addresses
This weekend I harvested 231 State of the Union addresses up to 2017 and put them through NLP processing.
