Produced by Sain (Recordiau) Cyf, this program is a continuation of the Welsh 1 program. It uses s similiar organizational format of dialogs, explanations of the main patterns used and carefully graded exercises. Welsh 2 gives greater attention to regional dialects and differences.

Understanding the Electromagnetic Field is an entry level textbook for graduate students with a focus on the electromagnetic field. This book explores the relationship between the field and electric charges.The earlier part of the book deals with the derivation of Maxwell's equations from experimental laws. Next, the electromagnetic field is studied in the light of special relativity, leading logically to the quantum theory of radiation. Quantum mechanics is introduced as a quantum field theory of the electromagnetic field. The rules of quantum mechanics are developed in a systematic way,...
