This illustrated survey covers what Nicholas Wade calls the "observational era of vision," beginning with the Greek philosophers and ending with Wheatstone's description of the stereoscope in the late 1830s.

Vision science has grown hugely in the past decades, but there have been few books showing readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. This book explains the computational principles and models of biological visual processing, and in particular, primate vision.

Words by tried and tested leaders not only encourage, but educate.

David Ellis’ Line of Vision has won the 2002 Edgar Award for Best First Novel by an American Author! Marty Kalish has been accused of murdering his lover's husband. He had a motive. He was at the scene of the crime. He manipulated evidence to hide his guilt. He even confessed. But that's not the end of the story. That's only the beginning.

Cassie Renfield finally has a handle on how the mark works. She knows she can intervene and attempt to change fate, but she also knows that saving one life could mean sacrificing another. The centuries old letter she found at the end of The Mark suggests she's a descendent of the Greek Fate, Lachesis, and that there are others out there with powers like hers. It's time to go find them. Now legally emancipated at 17, Cassie moves to Chicago to finish high school in a community where the Greek population is strong. She quickly discovers Demetria, a Greek girl who has visions of "the Angel of Death." But the Angel of Death is not Demetria, it's Zander-the cute Greek boy from school. His power allows him to help expedite a soul's journey from our world into the afterlife. He needs someone like Cassie-with the knowledge of a person's last day-in order to do his job successfully. But Cassie's not sure she's ready to willingly let marked people die....

Almost every organization has a vision. Few ever accomplish it. Even after short-term success in it, fewer stay true to it over time. Be Mean: Relentlessly Protecting the Vision is about regaining or sustaining the trajectory of the vision over time. It’s about staying true to the vision. Lovejoy explains that this requires understanding the importance of vision, developing a vision we’re willing to die for, and keeping the vision from being compromised or even hijacked. Though many books have been written on the subject of developing mission or vision statements, there have been few written on how to sustain or protect the vision over time. Shawn has dealt with hundreds of leaders in ministry and has seen countless struggle with keeping everyone on board with the mission and how to align the rest of the organization with the vision. Shawn Lovejoy walks the church leader through the experiences that have taught him to Be Mean, and shows us a strategy of Relentlessly Protecting the Vision.
