8.2. Columnar phase.
8.3. Crystal growth.
9. Conclusion.
Despite many of us staring at liquid crystals--in the form of liquid-crystal displays--for large portions of our waking life, for many their science and beauty is an untold story full of surprise and wonder. This book takes you on a photographic journey through the science of liquid crystals. By the end you'll be familiar with what they are, how they form and their role in producing the complexity of life on Earth. Presented in non-technical language, without any mathematics, this accessible text looks at spider webs, silk, display technology, lasers, dyes, detergents, DNA, cell membranes, drug delivery mechanisms, anaesthesia and optical computing. Presented in non-technical language and without any mathematics, this book is accessible to all, even if you have no prior knowledge of physics or chemistry.
