Essential Science : Welbeck : 9781787394469 : 1787394468 : 12 Nov 2020 : Essential Science aims to be the most detailed, accessible and authoritative book of its kind. Each of the 34 discoveries is broken down into seven essential elements to aid comprehension and inform the reader. THE ESSENTIAL IDEA a concise summary of the idea or discovery that makes complex ideas as simple as possible. ORIGINS: where does the discovery come from, who made it and how does it fit in the wider scientific context? KEY THEORIES AND EVIDENCE: even our most familiar ideas and discoveries are far from 'common sense'. How do we know what we know? What is the evidence? What are the dominant theories? CRITICS: science is a constant process of criticism and revision. How have various ideas survived attempts to discredit them? How secure is our knowledge and is it complete? WHY IT MATTERS: how important is the discovery in the wider scientific context? How much has it reshaped our perception of reality?
