Linear algebra now rivals or surpasses calculus in importance for people working in quantitative fields of all kinds: engineers, scientists, economists and business people. Gilbert Strang has taught linear algebra at MIT for more than 50 years and the course he developed has become a model for teaching around the world. His video lectures on MIT OpenCourseWare have been viewed over ten million times and his twelve textbooks are popular with readers worldwide.

Lithium depletion in the Universe remains a matter of investigation This book aims to carry out a wide-ranging inquisitive review of over half a century of astronomical observations of lithium and astrophysical developments to understand its behaviour in diverse environments across the Universe. The scope is wide, from the primordial nucleosynthesis in the early universe, to the evolution in the Milky Way and other galaxies and the internal processes that determine the depletion or preservation in stars, brown dwarfs and exoplanets.

This book guides you through the evolution of language models, starting from machine learning fundamentals. Rather presenting transformers right away, which can feel overwhelming, we build understanding of language models step by step—from simple count-based methods through recurrent neural networks to modern architectures. Each concept is grounded in clear mathematical foundations and illustrated with working Python code.
