 At the point of transition between wooden and metal ships, the engineer Isambard Kingdom Brunel skipped ahead and built an ambitious ship which, with a length of 211 meters, wasn't quite twice as big as the ones preceding it, the SSC Great Eastern. It represented a discontinuity of about 40 years. Afterwards, competition between liner companies (and later cruises) kept a discontinuity from arising, though ship size kept increasing.
 
-Two difficulties arise: Firstly, the most convenient data only includes passenger ships. However, both categories were synonymous in the period of interest: passenger ships were routinely the biggest ships at least until WW1 (S President, the SS British Queen, SS Great Eastern, the RMS Celtic, RMS Baltic, the RMS Titanic, etc). Nonetheless, at some point afterwards, other categories of ship, i.e., oil tankers become the biggest ships overall. R.C. Anderson's *Big Ships in History* serves as a sanity check on this. Secondly, the sizes of the ships of antiquity are not well recorded. For this reason, I just consider data for European ships, starting in the 19th century, and exclude f.ex., Chinese, Greek and Javanese naval history. I feel that this makes sense, because the  [Thalamegos's](https://en.wikipedia.org/wiki/Thalamegos) (200 BCE) size of 115 meters just wasn't surpassed by anything in Europe until the SS Great Eastern itself, although perhaps by poorly documented [Chinese](https://en.wikipedia.org/wiki/Louchuan) and [Javanese](https://en.wikipedia.org/wiki/Djong_(ship)#Decline) ships.

 ## Discontinuity in the circumnavigation of the Earth
 
 We find 4 discontinuities. Their precise magnitude depends on whether we measure time, or its logarithm. In both cases, we get very large discontinuities, plausibly of more than 100 years. However, our estimates are inexact. In particular, our data shines in the period 1870 - 1949, and thus the data is only great for the discontinuity created by the first circumnavigation by plane, which happened in 1931 and for which our two estimates are 11 and 40.5 years.

-- Saline solution for diarrhea
-- Discontinuities for yatch races
-- Transatlantic sailing record
+- Saline solution for diarrhea, as opposed to previous treatments.
+- Discontinuities for yatch races (A quick glance does not reveal any discontinuities. I do not intend to research this further)
