Entwicklungslinien des Aphorismus, The focus of this chapter is the electron microscope, an instrument critical to our understanding of a whole range of materials. The chapter also provides a brief history of scanning tunneling microscopy, a technique with the ability to provide atomic resolution images of the surfaces of materials.

,Key to the Genera and Species (♀♀),t Prize of the decade was for one in a rapid series of groundbreaking ideas that reflected uncertainty and, to many, an uncomfortable lack of precision. In the ten years following the award of the 1920 Nobel Prize in Physics to Charles-Edouard Guillaume, a metallurgist from the small Swiss watchmaki

Aphoristisches zwischen Physik und Dichtungectricity, a fair bet is it contains at least one lithium-ion battery. These creations of human ingenuity—requiring a detailed understanding of how materials interact at the atomic scale—power the ubiquitous smart devices that allow us to communicate with each other wherever we are in the world.

Georg Christoph Lichtenberg,Jürgen Teichmann . we use a total of 410 quintillion joules of energy. Every . we receive 430 quintillion joules of energy from the Sun. So, we get more energy from the Sun in 1 h than the world’s population uses in an entire year. While the first photovoltaic cells were dominated by silicon, recent research has id
