However, most people do not know that she would co-patent the technology for today's cellphones, Wi-Fi and GPS by building a torpedo for the U.S.Navy. This may have remained the world's best kept secret if it were not for author Richard Rhodes.

The Scientific Processes During Perming & Relaxing As we know, the hair is made up of protein chains held together by series of physical and chemical bonds which give the hair its shape and strength. The bonds we are most concerned with in styling the hair are the side bonds. Side bonds are found in two forms â physical side bonds and chemical side bonds. Breaking and reforming these side bonds allow us to rearrange the wave pattern of the hair. Physical side bonds can be broken using heat and water and reform when the hair dries and/or cools. However, this article is about perming and relaxing and the scientific processes that occur. When the hair is permed (and sometimes when straightened) the disulfide bonds (the chemical side bonds) of the hair are broken through a chemical reaction called âreductionâ. A reduction reaction involves either the removal of oxygen or the addition of hydrogen. In the case of permanent waving, the reduction is due to the addition of hydrogen.
