“All I could do was stare at the pages and caress them. … I hurried home, clutching the suites as if they were the crown jewels. … I read and reread them. I was thirteen at the time, but for the following eighty years the wonder of my discovery has continued to grow on me. Those suites opened up a whole new world. I began playing them with indescribable excitement. They became my most cherished music. I studied and worked at them every day for the next twelve years.” Pau Casals (1876 – 1973)

MIT – Introduction to Solid State Chemistry

This course explores the basic principles of chemistry and their application to engineering systems. It deals with the relationship between electronic structure, chemical bonding, and atomic order. It also investigates the characterization of atomic arrangements in crystalline and amorphous solids: metals, ceramics, semiconductors, and polymers (including proteins). Topics covered include organic chemistry, solution chemistry, acid-base equilibria, electrochemistry, biochemistry, chemical kinetics, diffusion, and phase diagrams. Examples are drawn from industrial practice (including the environmental impact of chemical processes), from energy generation and storage, e.g., batteries and fuel cells, and from emerging technologies, e.g., photonic and biomedical devices.

Neurologist and author Oliver Sacks brings our attention to Charles Bonnett syndrome — when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon.

Documentary which looks at how developments in mathematics over the past 40 years have completely changed our understanding of the fundamental nature of the world we live in.

As we approach tipping points in both the economy and the climate, the film examines the mathematics we have been reluctant to face up to and asks if, even now, we would rather bury our heads in the sand rather than face harsh truths.

Kvalitativní výzkum. Základní metody a aplikace
Jan Hendl · Vydavateľstvo: Portál, 2005

Metody kvalitativního výzkumu si získávají ve vědách o člověku a společnosti stále větší význam, ať jsou považovány za doplněk tradičních kvantitativních postupů, nebo jejich protipól. Jsou velmi užitečné v případech, kdy jde o zkoumání života lidí, historie i chodu organizací, společenských procesů apod. Příručka, jejíž přepracované a aktualizované vydání přinášíme, se již stala standardní učebnicí těchto metod u nás. Ukazuje, z jakých zdrojů metody kvalitativního výzkumu vycházejí, a představuje hlavní výzkumné plány užívané v této oblasti. Popisuje kvalitativní metody sběru dat, jejich kódování, vyhodnocování a interpretaci. Pozornost věnuje i počítačovým nástrojům sloužícím kvalitativnímu výzkumu, psaní zprávy o výzkumu a hodnocení jeho kvality.
