Dan Gill – författare

Perfect for classroom sharing and back to school, this poignant picture book based on a true story celebrates a beloved teacher and his commitment to making sure all kids feel welcome in his classroom.From art to science, history to math, there are so many things to learn at school! But Mr. Gill's students are most interested in learning about the empty chair that sits in the front of their classroom. He tells them a story from his childhood about his Black best friend, Archie, the racism they experienced at a classmate's birthday party, when Archie was told there wasn't a chair for him, and how it inspired Mr. Gill to prioritize inclusivity and love. In this true story of bravery and belonging from longtime elementary school teacher Dan Gill and gorgeously illustrated by Susan Gal, readers will learn to always keep an extra chair in their home and in their hearts.

Computers & Geology, Volume 3: Geomathematical and Petrophysical Studies in Sedimentology presents a collection of papers concerned with interpretation of sediment properties from mechanical logs and seismic profiles. This book covers stimulation of groundwater flow, atmospheric conditions, bed thickness, and stratigraphic data. Organized into 17 chapters, this volume begins with an overview of the FORTRAN program designed to duplicate and simplify the mental processes that lead to an interpretation of a depositional setting. This text then examines a simple stochastic sedimentation model of turbidite sequences that assumes a bed thickness corresponding to a waiting time between turbidity currents. Other chapters consider the study of a system''s response to different disturbances. This book discusses as well the Monte–Carlo model to reconstruct open-array correlation matrices from coefficients drawn from closed-percent systems. The final chapter deals with bivariate allometric equation. This book is a valuable resource for petroleum geologists and research workers.
