 WEEK1: Introduction Q1: Thinking about our learning 1. trained people can solve a particular problem, educated people can solve a wider range of problems. 2. Because environmental problems are rarely specific to a single subject, solutions are more likely to be improved by more education than training . 3. Whilst not the only selling point of an environmental scientist, the unique selling point(USP) is often an ability, achieved through education to recognise links between subject areas.  Q3: What is research 1.Writing the theory of evolution, the theory of special relativity and plate tectonics were types of induction .  These ideas which may have been derived from synthesis of a large amount of previous work or "thought experiments"were related to the real world.  Probably a large amount of research based on deduction was carried out before the induction was accepted, this may then have resulted in a paradigm shift . 编写进化论、特殊相对论和板块构造理论是正确归纳的类型。这些观念可能源于对大量先前工作或“思维实验”的综合，与现

If you recall the advection equation, this is a PDE or partial differential equation that describes the Lagrangian derivative, which is d/dt. In an Eulerian framework by breaking it down using the chain rule, as partial df/dt, plus the velocity multiplied by partial df/dx. And this is a one-dimensional advection equation. And we use this in previous weeks to look at the transport of rain between levels in a 1d column model, for instance. As we've been talking about, Newton's second law states, F equals ma or ma is equal to F. And we can write that as m times dV by dt because the acceleration is just the rate of change of velocity with respect to time. Now, here we have a Lagrangian derivative dV by dt, and for our model describing the motion of a fluid, we want to use an Eulerian framework. So we have to change this Lagrangian derivative into an Eulerian derivative.
