Readers who £nd this chapter while looking through the book will, more than likely, be surprised. What relationship can this exotic material have to such basic and everyday subjects like FELs? The author agrees that, strictly speaking, there is not a direct relationship. However, an indirect connection certainly exists and will be explored in this chapter. Nevertheless, it seems that in accepted serious science, using standard logic, this chapter would not be included in this type of book, but here it is. The explanation is fairly simple: the author has taken the advantage of poetic license. The author could not resist the temptation to share with readers the extraordinary discoveries in other areas besides that of ordinary oscillations and waves and he sincerely believes that readers will also £nd it as interesting as he did when he wrote these lines.
