Longman Originals is a series of graded readers in four stages. All the stories are original - that is to say, written especially for the series. Originated from the Longman Structural Readers, the series aims to offer a stimulating range of modern stories, including detective stories, adventure and romance.

The book explores the affairs of Mount Lebanon and its surrounds through fourteen centuries, beginning with the emergence of its Christian, Muslim and Islamic-derived communities between the sixth and eleventh centuries. Against this backdrop, it interprets the modern republic of Lebanon from... číst celé

By the time a baby is born, its brain contains nearly 100 billion intricately shaped neurons, forming a small, soft-matter supercomputer. This book serves as a step-by-step guide to understanding human brain development, from its earliest embryonic stages to birth and beyond. Written from an experimental neuroscientist's viewpoint, it offers a conceptual framework for developmental neurobiology, detailing the biological mechanisms—genetic, environmental, and stochastic—that significantly influence neural development. It explores the major questions that have driven the field forward, highlighting pioneering discoveries made by scientists worldwide and how the structures and mechanisms of the developing brain were uncovered. Chapters progress chronologically, tracking the growth of the human brain from conception to shortly after birth, while also recounting the history of these discoveries. The narrative integrates findings from studies of model organisms—such as nematodes, flies, frogs, fish, birds, mice, and non-human primates—demonstrating that similar processes and genes are involved across species. The book concludes by discussing the uniqueness of individual brains and how research on early neural development aids in understanding the genetic and embryonic origins of various neurological and cognitive traits that emerge later in life.

The story follows Lieutenant David, a dedicated naval officer whose life takes an unexpected turn when he becomes infatuated with Beth, the wife of his shipmate. As David navigates his feelings and the moral dilemmas that arise aboard the destroyer, he grapples with the tension between his duties and his desires.

The story explores themes of love, family loyalty, and the fight against adversity, culminating in a confrontation that tests Brandon's resolve and determination.

Książka ta jest kroniką nauki, która prowadzi do zrozumienia rozwijającego się mózgu. Rozpoczyna się od chwili narodzin, gdy matka bawi się paluszkami swojego dziecka, które, mimo że pochodzi z jej ciała, jest unikalne. Jego mózg, chroniony przez czaszkę, jest niezwykłym superkomputerem z miliardami neuronów tworzących biliony połączeń. Już od pierwszych chwil życia mózg gromadzi informacje o świecie i podejmuje decyzje, mimo że dziecko wymaga opieki. Ma zdolność integrowania instynktów i doświadczeń, eksplorowania, dotykania nowych tekstur oraz przeżywania emocji. Opowieść zaczyna się od zapłodnionej komórki jajowej, z której powstaje zarodek, a następnie neurony formują połączenia w rozwijającym się mózgu. Narracja koncentruje się na poziomie komórkowym, co ułatwia zrozumienie etapów powstawania mózgu. Zawiera pytania o to, jak komórki zarodka stają się neuronami, ich różnorodność, wpływ pochodzenia na przeznaczenie oraz procesy, które prowadzą do ich trwałości. Mimo małej skali, biografia neuronu jest dramatyczna, a książka otwiera okno na te wydarzenia. Wpleciona jest również opowieść o ewolucji ludzkiego mózgu, ukazująca, jak ludzie zdobyli swoje unikalne umysły.
