In Vera Rubin: A Life, Jacqueline Mitton and Simon Mitton provide a detailed, accessible overview of Rubin's work, showing how she leveraged immense curiosity, profound intelligence, and novel technologies to help transform our understanding of the cosmos. But Rubin's impact was not limited to her contributions to scientific knowledge. She also helped to transform scientific practice by promoting the careers of women researchers. Not content to be an inspiration, Rubin was a mentor and champion for hiring women faculty and honoring them with awards historically exclusive to men.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of. 

Educator. Innovator. Inventor. These three words sum up Alexander Graham Bell, one of the greatest scientific men of his era. He is most famous for the invention of the telephone, a device which he predicted would transform human society. And it did. But the telephone is just one of the many innovations and inventions that Bell brought into being. A man who epitomizes the word visionary, Alexander Graham Bell predicted the use of light as a medium for transmitting information and how humanity would be transformed by flight. This is his story.

Las revoluciones industriales originaron multitud de avances tecnológicos y uno de los más revolucionarios fue la invención del teléfono de masas.

The biography of the teacher of the deaf who, through his knowledge of music, human speech, and hearing, invented the telephone. Bell was a pioneer in many fields that aided communication over distances. He worked tirelessly to help the deaf communicate with others (even Helen Keller came to him for help). After the telephone, Bell invented the photophone (a device that uses a beam of light to transmit sound wirelessly), and developed phonographic sound recording methods.
