Rational numbers are those that can be expressed as fractions and Irrational Numbers totally blew Ancient Greek philosophers away, man!
Here are a few cool numbers about books and the like:
- 3,900,000,000 – approximate number of copies of the Holy Bible sold between 1962 and 2012 (Stylist Mag)
- 129,864,880 – total number of books in the world as of 2010 (Google Search blog)
- 32,000,000 – adults in the United States who couldn’t read when 2013 rolled around (U.S. Department of Education and the National Institute of Literacy)
- 1,084,170 – words in total in all seven Harry Potter novels (hp-lexicon)
- 237,500 – characters of text in an average book, calculated as 190 x 250 x 5 (some anonymous guy on Quora)
- 24,812 – average number of words that I write each month on this blog (my trusty calculator)
- 2,875 – number of new titles published per million inhabitants in the UK in 2014 – a world record for the year (IPA)
- 1,300 – copies of Paradise Lost (Poem by John Milton) sold within 2 years of its 1167 publication date (Literature, Culture, and Society – Andrew Milner).
- 108 – average number of books I have read per annum between 2013 and 2015 (Goodreads)
- 10 – number of totally random book and word related facts on this post (me).
And the fact that I spent time doing this proves beyond a shadow of a doubt that it’s not just numbers that can be irrational.
