Indhold:- Forudsætninger for et periodisk system- Grundstofbegrebet- Atomvægt- Begyndende systematisering- Det periodiske system- Hvem var opdageren?- Tiden efter 1870- Problemer- - Fire omvendte par- - Ædelgasserne- - Radioaktivitet- Atomnummerets opdagelse- Bohrs forklaring på det periodiske system- Den moderne atomfysik- Ordforklaringer- Litteraturliste og links- Vejledning: Sådan samles Courtines’ periodiske system- Tabel: Det periodiske system- Udklipsark til Courtines’ periodiske systemBogen er den eneste sammenfatning på dansk af hovedlinierne i udviklingen af teorien om materiens opbygning fra forestillingen om de fire elementer til vore dages idé om godt 100 forskellige grundstoffer. Hovedvægten ligger på etableringen af grundstofbegrebet og ikke mindst forsøgene på at ordne grundstofferne i et system på grundlag af deres kemiske og fysiske egenskaber.

Hvad fortæller videnskabelige teorier os om verden ud over, hvad vi kan observere? Dette filosofiske spørgsmål er særdeles påtrængende i lyset af kvantemekanikken. Og dets besvarelse er grundlaget for kvantefilosofien.Kvantemekanikken er fysikernes teori om atomerne og deres mindste dele. Ingen fysisk teori har vist sig mere succesrig i sine forudsigelser end den. Men siden Werner Heisenberg formulerede teorien i 1925, har der blandt fysikere og filosoffer hersket uenighed om, hvordan den nærmere skulle forstås. Især dens måde matematisk at repræsentere atomerne på voldte vanskeligheder, som det blandt andet sås i diskussionerne mellem Bohr og Einstein sidst i 1920'erne og 1930'erne. Og baggrunden for konflikten er fortsat lige til i dag.Det særegne ved atomerne er øjensynligt, at de opfører sig meget anderledes end større ting som kanoer, kanonkugler, katte og kakerlakker. Når man måler på atomare objekter, opdager man, at de kan "føle" hinanden over store afstande, at de kan optræde som en bølge eller som en partikel, og at de vekselvirker med hinanden - uden vi altid bagefter kan skelne deres gøren og laden. Alt sammen på grund af virkningskvantet. Alt til forskel fra den klassiske fysik.Vanskelighederne med at forstå kvantemekanikken har affødt mange, meget forskellige udlægninger: Nogle går ud på, at visse kvantemekaniske beskrivelser er komplementære, og andre handler om, at det er fysikerens bevidsthed, der indvirker på måleprocessen. Andre igen antager, at der findes skjulte variable, som får dem til at "føle" hinanden, mens endnu andre mener, at verden - hver gang vi observerer en bestemt tilstand hos det atomare objekt - opdeles i et utal af verdener. Bogen "Kvantefilosofi" redegør for første gang på dansk for disse mangfoldige fortolkninger, sætter dem ind i deres historiske fremkomst og forholder sig kritisk til dem.

Master the art and science of data storytelling--with frameworks and techniques to help you craft compelling stories with data.The ability to effectively communicate with data is no longer a luxury in today's economy; it is a necessity. Transforming data into visual communication is only one part of the picture. It is equally important to engage your audience with a narrative--to tell a story with the numbers. Effective Data Storytelling will teach you the essential skills necessary to communicate your insights through persuasive and memorable data stories.Narratives are more powerful than raw statistics, more enduring than pretty charts. When done correctly, data stories can influence decisions and drive change. Most other books focus only on data visualization while neglecting the powerful narrative and psychological aspects of telling stories with data. Author Brent Dykes shows you how to take the three central elements of data storytelling--data, narrative, and visuals--and combine them for maximum effectiveness. Taking a comprehensive look at all the elements of data storytelling, this unique book will enable you to:* Transform your insights and data visualizations into appealing, impactful data stories* Learn the fundamental elements of a data story and key audience drivers* Understand the differences between how the brain processes facts and narrative* Structure your findings as a data narrative, using a four-step storyboarding process* Incorporate the seven essential principles of better visual storytelling into your work* Avoid common data storytelling mistakes by learning from historical and modern examplesEffective Data Storytelling: How to Drive Change with Data, Narrative and Visuals is a must-have resource for anyone who communicates regularly with data, including business professionals, analysts, marketers, salespeople, financial managers, and educators.

This book explores the mathematical field of topology, giving a sense of the visual elements of the field, as well as the formal definition of continuity. Considering some of the eye-opening examples that led mathematicians to study topology, it pays homage to the historical people, problems, and surprises that propelled the growth of the field.

A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel-driven civilization.

Often calculus and mechanics are taught as separate subjects. It shouldn't be like that. Learning calculus without mechanics is incredibly boring. Learning mechanics without calculus is missing the point. This textbook integrates both subjects and highlights the profound connections between them. This is the deal.

In this stimulating and timely book, Amit Goswami, PhD, shatters the widely popular belief held by Western science that matter is the primary "stuff" of creation and proposes instead that consciousness is the true foundation of all we know and perceive. His explanation of quantum physics for lay readers, called "a model of clarity" by Kirkus Reviews, sets the stage for a voyage of discovery through the common ground of science and religion, the entwined nature of mind and body, and our interconnectedness with all of creation.
