People who refuse to accept the world as it is, who dare to... More

In this book, a modern unified theory of dispersion forces on atoms and bodies is presented which covers a broad range of different aspects and scenarios. Macroscopic quantum electrodynamics is applied within the context of dispersion forces. In contrast to the normal-mode quantum electrodynamics tr... More

Iatrogenesis is the occurrence of untoward effects resulting from actions of health care providers, including medical errors, medical malpractice, practicing beyond one’s expertise, adverse effects of medication, unnecessary treatment, inappropriate screenings, and surgical errors. This is a huge pu... More

Dispersion forces acting on both atoms and bodies play a key role in modern nanotechnology. As demonstrated in this book, macroscopic quantum electrodynamics provides a powerful method for understanding and quantifying dispersion forces in a vast range of realistic scenarios. The basic physical conc... More
