Two Proofs of Constant A/V Ratio Cell Growth and Division
If a cell maintains a constant ratio of surface area to volume as it grows, there are a variety of ways in which it can grow and divide.
For a cell, the advantage of maintaining a constant A/V ratio is that it only needs to produce surface membrane and internal ... | {"url":"https://cfrankdavis.wordpress.com/2012/10/08/two-proofs-of-constant-av-ratio-cell-growth-and-division/","timestamp":"2014-04-20T13:18:54Z","content_type":null,"content_length":"86038","record_id":"<urn:uuid:97426e46-e434-4355-bec9-8a985c096268>","cc-path":"CC-MAIN-2014-15/segments/1398223203235.2/warc/CC-MAIN-2... |

Are you seeing patterns in numbers everywhere? You're not crazy - it's Benford's Law.
Pick any large set of random data you like. Look at the first digit of all the numbers. You're going to see a lot of ones. It's not just a coincidence. It's the law.
