Quantum computing is an exciting subject that offers hope to solve the world’s most complex problems at a quicker pace. It is being used quite widely in different spheres of technology, including cybersecurity, finance, and many more, but its concepts, such as superposition, are often misunderstood because engineers may not know the math to understand them. This book will teach the requisite math concepts in an intuitive way and connect them to principles in quantum computing.Starting with the most basic of concepts, 2D vectors that are just line segments in space, you'll move on to tackle matrix multiplication using an instinctive method. Linearity is the major theme throughout the book and since quantum mechanics is a linear theory, you'll see how they go hand in hand. As you advance, you'll understand intrinsically what a vector is and how to transform vectors with matrices and operators. You'll also see how complex numbers make their voices heard and understand the probability behind it all.It’s all here, in writing you can understand. This is not a stuffy math book with definitions, axioms, theorems, and so on. This book meets you where you’re at and guides you to where you need to be for quantum computing. Already know some of this stuff? No problem! The book is componentized, so you can learn just the parts you want. And with tons of exercises and their answers, you'll get all the practice you need.

Apache Spark is a unified data analytics engine designed to process huge volumes of data quickly and efficiently. PySpark is Apache Spark's Python language API, which offers Python developers an easy-to-use scalable data analytics framework.Essential PySpark for Scalable Data Analytics starts by exploring the distributed computing paradigm and provides a high-level overview of Apache Spark. You'll begin your analytics journey with the data engineering process, learning how to perform data ingestion, cleansing, and integration at scale. This book helps you build real-time analytics pipelines that help you gain insights faster. You'll then discover methods for building cloud-based data lakes, and explore Delta Lake, which brings reliability to data lakes. The book also covers Data Lakehouse, an emerging paradigm, which combines the structure and performance of a data warehouse with the scalability of cloud-based data lakes. Later, you'll perform scalable data science and machine learning tasks using PySpark, such as data preparation, feature engineering, and model training and productionization. Finally, you'll learn ways to scale out standard Python ML libraries along with a new pandas API on top of PySpark called Koalas.By the end of this PySpark book, you'll be able to harness the power of PySpark to solve business problems.

Statistics remain the backbone of modern analysis tasks, helping you to interpret the results produced by data science pipelines. This book is a detailed guide covering the math and various statistical methods required for undertaking data science tasks.The book starts by showing you how to preprocess data and inspect distributions and correlations from a statistical perspective. You’ll then get to grips with the fundamentals of statistical analysis and apply its concepts to real-world datasets. As you advance, you’ll find out how statistical concepts emerge from different stages of data science pipelines, understand the summary of datasets in the language of statistics, and use it to build a solid foundation for robust data products such as explanatory models and predictive models. Once you’ve uncovered the working mechanism of data science algorithms, you’ll cover essential concepts for efficient data collection, cleaning, mining, visualization, and analysis. Finally, you’ll implement statistical methods in key machine learning tasks such as classification, regression, tree-based methods, and ensemble learning.By the end of this Essential Statistics for Non-STEM Data Analysts book, you’ll have learned how to build and present a self-contained, statistics-backed data product to meet your business goals.

Edward Pasewicz Dolna Wilda Estella M. G. Co chciałbyś nam powiedzieć mały filozofie, kruszynko światła? Popatrz, mam takie wąskie usta, kiedy się śnisz, przechodzę przez bramę. Czy myślisz, że któregoś snu utknę na zawsze, jarząc się przez chwilę jak brutalnie zalane wodą ognisko, skierki unoszące się w powietrzu? Czy może zostanę jak popiół? W drobnych dłoniach będziesz mnie trzymał i w ptasi sposób p... Edward Pasewicz ur.9 czerwca 1971 Najważniejsze dzieła:Dolna Wilda (2001), Henry Berryman Pięśni (2006), Drobne! Drobne!

Esterka i inne kobiety Kazimierza Wielkiego

Esterka, Esterka Małach (XIV wiek) słynąca z urody Żydówka, według kronikarza Jana Długosza ukochana (kochanka) króla Kazimierza Wielkiego. Była wnuczką szanowanego kupca i lekarza z Opoczna i znała wiele tajemnic medycznych. Podobno miała z królem dwóch synów: Niemira i Pełkę. Według Długosza, który wspomina ją pod datą 1356. Właśnie we wpływie Esterki należy doszukiwać się tak dobrej polityki króla względem polskich Żydów. Marcin Bielski zaś w swojej Kronice wszytkiego świata opisuje Łobzów jako miejsce gdzie Kazimierz chował miłośnicę z Czech Rokiczankę, która była niepospolitej cudowności, ale nią potem wzgardził, a Esterkę Żydówkę na jej miejsce wziął.
