This classic book offers the reader advice and instructions on how to best appreciate nature, the countryside, and walking in the Great Outdoors. It aims to enlighten the reader as to what to look out for and how to identify various things ranging from trees to wildlife and beyond. "Going About The Country - With Your Eyes Open" is highly recommended for nature lovers and is perfect for those looking for new ways to appreciate their natural surroundings. Contents include: "Eyes that See," "The Art of Sitting Down," "Woodcraft," "Eyes and no Eyes in the Woods," "Signs and Tokens," "The Woodman's Secrets," "How to Call the Birds and Beasts," "Some Uses of Hazel and Ash," "How to Know the Trees," "Our Friend the Gamekeeper," "Thoughts on Trespassing," "Odd Hours of Sport," etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author.

Learn How to Program Stochastic ModelsHighly recommended, the best-selling first edition of Introduction to Scientific Programming and Simulation Using R was lauded as an excellent, easy-to-read introduction with extensive examples and exercises. This second edition continues to introduce scientific programming and stochastic modelling in a clear, practical, and thorough way. Readers learn programming by experimenting with the provided R code and data. The book’s four parts teach: Core knowledge of R and programming conceptsHow to think about mathematics from a numerical point of view, including the application of these concepts to root finding, numerical integration, and optimisationEssentials of probability, random variables, and expectation required to understand simulationStochastic modelling and simulation, including random number generation and Monte Carlo integration In a new chapter on systems of ordinary differential equations (ODEs), the authors cover the Euler, midpoint, and fourth-order Runge-Kutta (RK4) schemes for solving systems of first-order ODEs. They compare the numerical efficiency of the different schemes experimentally and show how to improve the RK4 scheme by using an adaptive step size. Another new chapter focuses on both discrete- and continuous-time Markov chains. It describes transition and rate matrices, classification of states, limiting behaviour, Kolmogorov forward and backward equations, finite absorbing chains, and expected hitting times. It also presents methods for simulating discrete- and continuous-time chains as well as techniques for defining the state space, including lumping states and supplementary variables. Building readers’ statistical intuition, Introduction to Scientific Programming and Simulation Using R, Second Edition shows how to turn algorithms into code. It is designed for those who want to make tools, not just use them. The code and data are available for download from CRAN.
