Thermodynamics (Part 1) - Khan Academy Defining City Regions 2.3 Exploring for coal Early miners would have found it easy to trace the distinctive black colour of coal along an outcrop (for example, a coastline or river valley), and surface trenches were used to locate less obvious outcrops. However, tracing an outcrop underground was problematical as the only means of exploration was by digging costly trial shafts. The development of exploratory steam-powered drilling in the early 19th century improved matters, but it was not until the mid- to late- 20th century that more a 7.4.3 Modelling errors be aware that it is often possible to provide an estimate of error for numerical values derived from the application of theoretical models to a data set. For me, thinking about the use of models convinces me of some of the benefits of ‘problematising’ science – as we've been doing in the commentary so far. Indeed, my feeling is that using models reflects something more general about how scientific understanding is built up.
