Finite Field Fun - A lightweight introduction to finite fields and their applications for engineers computer scientists and others

Riccardo Bernardini

Summary

Finite field theory is a powerful algebraic tool used in many modern applications: from cryptography to digital transmission.  The traditional way to introduce finite field theory is within a course of algebra, after the introduction of groups and rings. This makes finite field theory a challenging subject for those who need to use them, but do not have a strong algebraic background (e.g., electrical engineers, software engineers, programmers,..).  This book aims to give a rigorous and solid introduction to the matter, while requiring only the basic notions about complex numbers.  At the end of the book, the readers should be able to use finite fields in their application and should also find easier to read more advanced books on this matter.  Part of the book is also devoted to describe the algorithms to actually use finite field in software, a crucial aspect not always discussed in algebra books (aimed to a more mathematical audience).

Peak of the Devil: 100 Questions...

Chip Haynes

What’s that peak oil thing you keep jabbering on about? 
“Peak oil” is the phrase used to describe the point where the world’s oil supply, well, peaks. A fairly easy concept there. It’s the best we can do, and the best we will ever do, when it comes to pumping conventional crude oil out of the ground. After peak oil, it’s all downhill, production-wise. 
Too many people think that peak oil means that the oil is going to run out, and that’s not quite right. The oil will not run out. Not ever. It will, over time, get increasingly rare and probably expensive (before it’s worthless), but there will always be at least a little bit of oil for us to use. Well, for someone to use. Probably not you and me, unless I sell a whole shipload of books. No pressure.

Transform Your Life And Save The...

Jeremy Griffith

This Second Edition of Transform Your Life And Save The World was published in 2019 and amended in 2021. The book is supported by a very informative website at www.humancondition.com 
The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book. 
Titled Transform Your Life And Save The World - Through The Dreamed Of Arrival Of The Rehabilitating Biological Explanation Of The Human Condition, this book is a very short but powerful condensation of Griffith’s definitive treatise of the human condition that is presented in his book FREEDOM: The End Of The Human Condition. 
The genesis of Transform Your Life And Save The World lay in Griffith’s address at the June 2016 launch of FREEDOM at the Royal Geographical Society in London. Commencing with very brief extracts from Tim Macartney-Snape’s Introduction at the launch, and Sir Bob Geldof’s keynote address, it goes on to summarise FREEDOM’s content in 3 powerful chapters: ‘The Dishonest Biology’, ‘The Truthful Biology’, and ‘The Resulting Transformation Of The Human Race’. 
As Professor Harry Prosen, a former President of the Canadian Psychiatric Association, has said, “I have no doubt this biological explanation of the human condition is the holy grail of insight we have sought for the psychological rehabilitation of the human race.”

iJesus - The Culture of God in a...

Nadim Nassar

Every aspect of life in today’s world is affected by digital technology, be it the way we communicate, travel, or shop, or even how we identify ourselves.

 
Christians, believing that we are created by a living personal God who revealed himself as Father, Son and Holy Spirit and came to us in Jesus Christ, try to make sense of their faith in this digital jungle.

 
iJesus explores the relationship between the culture of God as Trinity in relation to our highly complex digital cultures and reflects on how we as followers and disciples of Jesus Christ can live in a world shaped by digital communication, connectivity and artificial intelligence.

 
In the culture of the Trinity, we see a God who is the source of hospitality and generosity in everything he does and in every way that he reacts with His creation.

 
Nadim Nassar gives a prophetic vision of our faith interacting and being lied out in the changing cultures around us and shows how God can make himself known and understood in a digital age.

Celestial Ghosts - Dark Matter's...

Dirk Fallon

Dark matter is one of the most elusive and mysterious components of the universe. It is invisible, yet its existence is inferred from the gravitational effects it has on visible matter, such as stars and galaxies. Despite being a significant part of the cosmos, dark matter has yet to be directly detected, which makes it an intriguing subject for astrophysicists. It is believed to make up about 27% of the universe's total mass and energy, far outpacing the visible matter that forms stars, planets, and galaxies.
The name “dark matter” was coined to reflect the fact that it does not emit, absorb, or reflect any form of electromagnetic radiation, making it invisible to current instruments. This absence of interaction with light or other electromagnetic forces is why it cannot be seen directly. However, dark matter’s presence is undeniable when looking at the way galaxies move. Without dark matter, galaxies would not have the gravitational pull necessary to prevent their stars from flying apart as they spin. This leads scientists to believe that dark matter provides the gravitational glue that holds galaxies, and indeed the entire universe, together.
One of the key pieces of evidence for dark matter comes from the study of galaxy clusters. When observing these massive cosmic structures, scientists noticed that the visible matter within them didn’t account for the full gravitational force required to keep the clusters intact. This discrepancy suggested the presence of an unseen substance, later named dark matter, that was exerting additional gravitational pull. Another significant clue comes from the phenomenon of gravitational lensing, where light from distant objects bends around large masses. Dark matter’s influence on this bending further supports the idea that it is present in quantities far larger than what we can observe.
