Functional Programming Using F#
Functional Programming Using F#
Price: £29.92

5.0 out of 5 stars Great book - Will get you programming in F# to high standards; delivering functional programmes for the .Net platform, 5 Mar. 2014
Verified Purchase(What is this?)
A proper introduction to F# - Includes:
- F#'s use as a functional language - to a good programming standard using the functional style in the way academia intends
- F#'s place as another .NET language

For the academics
- Doesn't explain the academic theory behind functional programming, so won't have you thinking in B-reductions, etc


From Paradox to Reality: Our Basic Concepts of the Physical World
From Paradox to Reality: Our Basic Concepts of the Physical World
by Fritz Rohrlich
Edition: Paperback
Price: £39.99

5.0 out of 5 stars The Best Popular Science Book I've Read Introducing Theoretical Physics, 3 July 2012
From Paradox to Reality should be a classic text. It not only gives the reader an overview of the philosophy science but in doing so, allows a coherent popular introduction to be given to Newtonian Mechanics, Special Relativity, General Relativity and Quantum Mechanics. I read until the end of the section on General Relativity when I was towards the end of my undergrad in mathematics, but found the section on Quantum Mechanics intractable, so gave up.

14 years later having thought a lot about the foundations of maths and having dealt with a lot of partial information in a career in IT, I returned to the Quantum Mechanics section and found it wholly accessible and enlightening. It references the generalisation of Jon Von Neumann of both Heisenberg and Dirac's Matrix Theory and Schrodinger's Wave Mechanics and states their mathematical equivalence. It also covers the existence and place of the various Quantum Field Theories and the search for the Grand Unified Theory superficially, placing them in context with one another. This brief conclusion on the forefront of theoretical physics as at 1992 concludes the book most tidily. The interested and expert reader will find much to follow up on, whilst the thinking layman will get more out of this than the many better known popular texts on theoretical physics.

I also liked the description provided of some of the key experiments providing empirical evidence to motivate the theory.

It is a popular science book, for something that bridges the gap between popular science and mathematical/experimental physics I'd look to "The Road To Reality" by Roger Penrose. Roger Penrose's book also covers cosmology, which this book doesn't touch on.

If truly interested in Theoretical Physics you could do a lot worse than buying both and reading this first.

Anyone interested in a popular account of the philosophy of maths might enjoy "Godel's Proof" by Nagel and Newman

Together all three provide a fantastic overview of the state of mathematics and Physics today

5.0 out of 5 stars If you are a novice and want to get to good intermediate - the place to start, 10 Jun. 2011
Verified Purchase(What is this?)
This book was one of two key books in making more advanced guides more accessible to me (the other being 'Building a Data Warehouse with Examples in SQL Server').

In giving this review 5 stars I wanted to try and even out the two 1 stars it received previously. I still use this book for reference and for a beginner who wants to become good-expert and build a career in SQL Server this is the place to start. I bought 5 or 6 'beginners' guides, including Microsoft's MSTC Exam books and this was the one I settled on and read cover-cover twice (2005 and 2008 editions). Its not easy to get good at databases off your own back, but if you want to do it this is a great place to start.

If all you want is to learn to write a few simple SQL queries, being led by the hand 100% then I agree the previous reviews have some merit. But as this book helped me transform my career and increase my take-home pay 3-fold I couldn't let it sit on Amazon with 1 star. Thanks to the author!!!

Honestly - it does a very good job of introducing database concepts and T-SQL syntax to a workable level. I would have probably settled on 3.5-4 stars had previous reviews not been so bad.

I would agree with the first review's general comment that the book is at times unstructured and you probably need to be familiar with Primary Key and Foreign Key concepts. That assumed I loved the fact you had to deal with normalisation first and though a touch chapter it made the rest of the book a breeze once understood to a workable level.

Perhaps me and the first reviewer would agree a more appropriate title would be:
MICROSOFT SQL SERVER 2008 AN INTERMEDIATE'S GUIDE ... If that's the title, this is the best I've found


Database in Depth: Relational Theory for Practitioners: The Relational Model for Practitioners
Database in Depth: Relational Theory for Practitioners: The Relational Model for Practitioners
by C.J. Date
Edition: Paperback
Price: £17.46

5.0 out of 5 stars A concise introduction to the relational vision and where SQL falls short - Somewhat perversely helped improve my SQL skills, 1 Jan. 2011
I have just read Chris Date's book cover-to-cover.

It's foreword and back cover are accurate: In essence promising to provide an in-depth view of what the Relational Vision is, how it is intended to be used, where SQL meets this relational vision, where it falls short and discusses work arounds where they are available.

To write such a book C.J. DATE has clearly mastered not only first-order logic and the relational model, but also SQL to a standard (no pun intended) where he is justifyably able to act as an authority on it.

Consequently I find his comments unbiased, logically correct and of great interest. Of course to acknowledge yet challenge SQL (the world's dominant database language) he is necessarily opinionated, but I get the impression he would agree with the foreword when it says 'You may not agree with everything Chris says, and you don't need to, but you do need to understand it'.

As a result I want to back the comment of another reviewer that Chris's style 'does not basically serve as propaganda on why he is great and all other commentators are wrong', but simply 'that commentators who don't follow the relational model are HIGHLY flawed.'

On a separate note, I did find a background in formal and pure mathematics helpful in getting the most out of this book, but agree such a background isn't a necessity - This is the most concise book I have seen that gets at the heart of the relational model and where SQL differs from it. With thought the information in its 200 pages will allow you to become a master of SQL on your chosen DBMS more efficiently (my goal in reading the book, at least for now) and ensure you appreciate where SQL falls genuinely short of the relational vision and we might ultimately be better starting again.

Additionally there is a very useful appendix with references to further material for those wishing to become true experts in database theory.

5.0 out of 5 stars The best and toughest popular science book to date - Destined to be a classic!!, 8 Dec. 2007
Eventually History remembers the great books - "The Road to Reality" is a true work of art, destined to be a classic - It is the first genuine attempt to cover in one book the state of theoretical physics today. Where other popular science books attempt to simplify the theory and omit equations, thereby reducing themselves to talking about the theory ... "The Road to Reality" PRESENTS the theory. It is a subtle, but important difference that I will try to illuminate in the rest of this review.

"The Road to Reality" makes the modern theories of physics easily accessible to mathematicians and layman alike, in a self-contained text. It achieves this by virtue of being the first popular science book on theoretical physics to devote its first 16 chapters to introducing the reader to the pre-requisite Mathematics and `Philosophy of Science' necessary to understand the theoretical physics presented in chapters 17 to 34. The book is littered with necessary equations, but all are introduced in a logical, intuitive manner and provided with some of the best explanations in words and pictures that I have seen to date.

As such the equations can be viewed merely as markers in the text if reading as a popular science book. Conversely they can be used to guide the serious theoretical physicist in attempting the minimal but carefully chosen and difficult exercises, and any mathematical investigations the reader may be inspired to conduct themselves upon reading the beautiful exposition of physical theories of our universe.

As justified above, the best thing about the book is its 1094 pages can be read at various levels .... from a cursory glance (genuinely constituting popular science, albeit a difficult read) or as serious academic study (taking you well into a post-graduate level appreciation of mathematics and theoretical physics). For the academic, it will accelerate your path to becoming a rounded theoretical physicist. Every school should own this book and every potential student of maths or theoretical physics should attempt to read it pre-university.

There is no room for dubious analogies in "The Road to Reality", which removes the scope for confusion. Apologies to those readers who like analogy, but there is no place for it in theoretical physics - Communicating an understanding of what the theory is really about, to a level that it seems intuitive to the reader, is the goal of this book.

It's my favorite book of all time. I can't recommend it more highly than that!!
