I recommend this excellent book on relativity and light, including an essay titled "What happens if the speed of light slows down to 3000 m/s."
A must for aspiring physicists and mathematicians! Beginners can also read the book as it is self explanatory and easy to understand.

Here is an excerpt of the book:
Description: Studies have shown that approximately one in five adults will suffer from some form of depression or anxiety in their lifetime. This book will focus on non-conventional approaches to solve depression and anxiety, such as using herbal therapies like St John's Wort, 5-HTP, SAM-e, and Valerian Root. Changes to lifestyle and food habits will also be discussed. Professional psychiatrists and psychologists are unlikely to write such a book, so a book by a patient suffering from Anxiety and Depression is ideal, and perhaps the only way. The book will focus on many alternative approaches to help anxiety and depression, other than medication, which can be costly and have many side effects that are not well tolerated. In Singapore, currently there are not many local books on anxiety and depression, which are the two most common psychological disorders, and even fewer on alternative treatments. Good luck in battling anxiety and depression!
