Bradley Steffens – författare

Award-winning author Bradley Steffens introduces Ibn al-Haytham in this first full biography ever written about him. Though not a household name as far as the history of science goes, with his major contributions going largely unnoticed and uncredited, Ibn al-Haytham, who lived a thousand years ago, is finally being recognised as the world's first true scientist. Centuries before better-known researchers such as Roger Bacon, Leonardo da Vinci, and Galileo Galilei were born, Ibn al-Haytham investigated eyesight and the propagation of light in a profound manner, the likes of which had never before been fully utilised, and documented his findings in his magnum opus Book of Optics. By systematically using experiments to test his hypotheses, Ibn al-Haytham changed the course of human history, giving humankind a new and effective way of establishing facts about the natural world -- an approach known today as the scientific method.

In this sequel to The Prisoner of Al-Hakim, Alhasan Ibn al-Haythammathematician, astronomer, and physicist of the Islamic Golden Agecontinues his lifelong pursuit of knowledge, embarking on a daring journey with a new purpose. What begins with his curiosity about the green streaks that light up the sky leads him to The Empty Quarter in search of the fabled Crystal Oasis. Guided by Qur'anic verses and his relentless curiosity, Alhasan believes the site may hold the remnants of a fallen star.? While Alhasan chases after celestial mysteries and seeks the iron hidden in the earth, Sadeem, his newlywed wife, undertakes a journey of her own. Summoned by Governor Jalal al-Dawla, she introduces him to her husband's groundbreaking discoveries about light and vision. The Empty Quarter takes readers on two parallel adventuresone into the vast desert sands, the other into the halls of power. Both are filled with challenges, revelations, and the unyielding spirit of discovery that defined one of history's greatest scientific minds.
