What a little gem of a book!, 24 Dec 2007
A perfect book! My 11 year old daughter was entranced by the 1089 problem, and would be reading the book now, except I gave our copy to a friend, (have just ordered another three for us and any other casual callers). I'm doing a maths PhD and I loved it, and have learned things from it. Each chapter leads through a new idea, entertainingly written, but also, for example, giving a clear andsimple introductory explanation of calculus. I think all maths teachers should be given a copy, and should use it in class! Also explains what maths can do, what's it FOR! Absolutely recommended for maths lovers and maths-phobes alike.

Perfect for lecturers, teachers, students, pupils and those with just a vague interest, 17 Oct 2007
Alarmed at how much of my children's maths lessons was being lost to determining who had thrown this or that piece of paper, I sought a source of inspiration to keep their love of mathematics alive. I have found it. "1089 and all that" is perfect for the job.

Do not think that this is a book aimed at children, though, it is suitable for everyone, including lecturers and will be of benefit to many. First year students obliged to take a maths course will find many stimulating thoughts, though they should read the book with caution, they might just find themselves wanting to major in maths. Such late discovery of the joys of maths could be avoided by presenting all maths and physics teachers with their personal copy to enable them to liven up their classes with interesting asides, I suspect that, if only he could be motivated to do so, Acheson could inspire the least interested slob to stop throwing trajectiles and study their motion instead.

I had imagined that the task of building up my children's flagging interest might be slightly forced, even once I'd identified a suitable book, but I couldn't have been more wrong. Just a quick look at the first few pages on-line sent my sons charging off to tell their friends to "Think of a three digit number..." And now that it has arrived, I am redundant, because David Acheson's little hardback, does a far better job than I could ever do. Clear text, amusing cartoons, diagrams, and even blackboard look alikes, every page is a feast. "1089 and all that" is a book that you could race through, but you probably won't because you will wish to savour every tasty morsel of this cordon bleu fare.

Smashing!, 16 Oct 2005
A great little book, which makes mathematics accessible to anyone who wants to know. Written in a really friendly, non-condescending manner; Acheson wants you to like his subject, but takes great care not to force it upon you. Recommended for mathematicians looking for a spot of light relief, and non-mathematicians who just want to know a little bit more.

Interesting and concise, 21 Jun 2004
I had the pleasure of attending a summer school at Oxford where the maths lectures were taken by David Acheson. On the back of that, I bought this book and I'm glad I did! It's interesting and manages to explain things without patronizing those readers with mathematical knowledge, and yet helps those with very little. Highly recommended!

A fascinating little book!, 20 Mar 2004
I am currently training to be a maths teacher, and bought this book largely out of curiosity. But what a great little book! It is written in a style that is understandable to anyone without a great deal of mathematical knowledge, but is still interesting to anyone with a maths background. The style is lively and entertaining, and there are plenty of pictures and diagrams. Chapters such as 'The Trouble with Algebra', 'On being as Small as Possible', 'Are We Nearly There?', 'What is the secret of All Life', and 'Not Quite the Indian Rope Trick' introduce topics such as algebra, geometry, caluculus, infinity and far, far more. It has lots of fascinating little snippits that appealed not only to me, but also to my husband (who is not a mathematician), and my 13 year-old son. A lovely little book!

Ian Stewart takes us on a journey through group theory to places you probably never considered, but in a completely fun and accessible manner. The historical tone of the book works really well, this book has inspired me to study galois theory in far greater depth.

A MUST for anybody with an interest in mathematics.

Algebra HELP!, 14 Nov 2005
I've just started a university course that i needed a little element of Algebra to make certain calculations

This book explains topics very well. The only things which i think it lacks is having questions that the reader can work through to improve their own skills.

Great book, but only good for reference/understanding.

Sadly, not a book for everyone, 25 Jun 2007
Really interesting book which puts currently taught mathematics into its historical context. I bought the hardback which has "even algebraphobes will struggle to find fault" - don't believe a word of it: I don't think I would have understood much of the book without having done first year university pure maths already and would not recommend it to non math-inclined friends. There were a few typos in my edition but not enough to cause too many problems.

A Rollercoaster ride through the history of algebra... Hold on tight!, 05 Jul 2006
I've long been interested in the history of science and mathematics and have to say that this book is an absolute treat to read.

I read John Derbyshire's other historical mathematics book - "Prime Obsession" - about a year ago and was mightly impressed. His ability to weave historical facts with some of the more complicated mathematics is something that a lesser author would stumble with. Not Derbyshire. "Unknown Quantity" takes "Prime Obsession" further - as it were - leaving behind one specific area of mathematical intregue (the Reimann Hypothesis) and covering this time the entire field of the history and development of algebra. Its a interesting feat to attempt given the huge subject base and the literally hundreds (if not few thousands) of years of history that have to be covered, but he does it well. Along the way we encounter ALL of the big names in maths: Galois, Lagrange, Euler (to name but a few) and some others that you may not have heard of, all of them though have their own backstories that make the characters come alive on the page (it is amazing how often some form of tragedy befalls a member of the mathematical elite of the 18th and 19th centuries).

But it's not all history. Derbyshire deftly takes us through some simple examples - how to solve the general cubic equation (and extend this to the general quartic) in a detailed yet unpatronising way - and goes further into some of the more abstract areas of modern mathematics (fields, algebras and manifolds).

This is a fabulous book that takes us from ancient civilisations in the middle-east through europe in the 18th and 19th centuries and out to the present day, and leaves you with a sense of awe at what was achieved and what could yet be discovered in this most intreguing of mathematical fields.

Excellent introduction to medium level algebra, 26 Dec 2007
An excellent intro to medium level algebra. I bought this book (and its companion - algebra 1 for dummies) in order to be able to help our teenage daugher with her maths. I have no mathematical background beyond an exam when I was 15 - and that was 30 years ago. But the book is clear, user-friendly and easy enough to read at bedtime! Strongly recommended. Ditto for Algebra 1 for dummies and the accompanying workbook.

Derbyshire deftly takes us through some simple examples - how to solve the general cubic equation (and extend this to the general quartic) in a detailed yet unpatronising way - and goes further into some of the more abstract areas of modern mathematics (fields, algebras and manifolds).

This is a fabulous book that takes us from ancient civilisations in the middle-east through europe in the 18th and 19th centuries and out to the present day, and leaves you with a sense of awe at what was achieved and what could yet be discovered in this most intreguing of mathematical fields.

Excellent introduction to medium level algebra, 26 Dec 2007
An excellent intro to medium level algebra. I bought this book (and its companion - algebra 1 for dummies) in order to be able to help our teenage daugher with her maths. I have no mathematical background beyond an exam when I was 15 - and that was 30 years ago. But the book is clear, user-friendly and easy enough to read at bedtime! Strongly recommended. Ditto for Algebra 1 for dummies and the accompanying workbook.

Best Decision Ever Made, 12 Aug 2007
I was never one for math in school, but when I left into the real world I relaised my math skills needed brushing up on.

All of the 'crap' I learnt in secondary school and forgot every term, or holiday, came straight back to me in seconds because of how well this book is written and layed out.

I am only at chaper 3 so far, and I have just completed a load of basic GSCE online Algebra tests with brilliant results. (BBC BYTESIZE)

I probably sound like i'm selling detergent, but seriously, I owe a lot to this book and Mary Jane is damn fine.

What a little gem of a book!, 24 Dec 2007
A perfect book! My 11 year old daughter was entranced by the 1089 problem, and would be reading the book now, except I gave our copy to a friend, (have just ordered another three for us and any other casual callers). I'm doing a maths PhD and I loved it, and have learned things from it. Each chapter leads through a new idea, entertainingly written, but also, for example, giving a clear andsimple introductory explanation of calculus. I think all maths teachers should be given a copy, and should use it in class! Also explains what maths can do, what's it FOR! Absolutely recommended for maths lovers and maths-phobes alike.

Perfect for lecturers, teachers, students, pupils and those with just a vague interest, 17 Oct 2007
Alarmed at how much of my children's maths lessons was being lost to determining who had thrown this or that piece of paper, I sought a source of inspiration to keep their love of mathematics alive. I have found it. "1089 and all that" is perfect for the job.

Do not think that this is a book aimed at children, though, it is suitable for everyone, including lecturers and will be of benefit to many. First year students obliged to take a maths course will find many stimulating thoughts, though they should read the book with caution, they might just find themselves wanting to major in maths. Such late discovery of the joys of maths could be avoided by presenting all maths and physics teachers with their personal copy to enable them to liven up their classes with interesting asides, I suspect that, if only he could be motivated to do so, Acheson could inspire the least interested slob to stop throwing trajectiles and study their motion instead.

I had imagined that the task of building up my children's flagging interest might be slightly forced, even once I'd identified a suitable book, but I couldn't have been more wrong. Just a quick look at the first few pages on-line sent my sons charging off to tell their friends to "Think of a three digit number..." And now that it has arrived, I am redundant, because David Acheson's little hardback, does a far better job than I could ever do. Clear text, amusing cartoons, diagrams, and even blackboard look alikes, every page is a feast. "1089 and all that" is a book that you could race through, but you probably won't because you will wish to savour every tasty morsel of this cordon bleu fare.

Smashing!, 16 Oct 2005
A great little book, which makes mathematics accessible to anyone who wants to know. Written in a really friendly, non-condescending manner; Acheson wants you to like his subject, but takes great care not to force it upon you. Recommended for mathematicians looking for a spot of light relief, and non-mathematicians who just want to know a little bit more.

Interesting and concise, 21 Jun 2004
I had the pleasure of attending a summer school at Oxford where the maths lectures were taken by David Acheson. On the back of that, I bought this book and I'm glad I did! It's interesting and manages to explain things without patronizing those readers with mathematical knowledge, and yet helps those with very little. Highly recommended!

A fascinating little book!, 20 Mar 2004
I am currently training to be a maths teacher, and bought this book largely out of curiosity. But what a great little book! It is written in a style that is understandable to anyone without a great deal of mathematical knowledge, but is still interesting to anyone with a maths background. The style is lively and entertaining, and there are plenty of pictures and diagrams. Chapters such as 'The Trouble with Algebra', 'On being as Small as Possible', 'Are We Nearly There?', 'What is the secret of All Life', and 'Not Quite the Indian Rope Trick' introduce topics such as algebra, geometry, caluculus, infinity and far, far more. It has lots of fascinating little snippits that appealed not only to me, but also to my husband (who is not a mathematician), and my 13 year-old son. A lovely little book!

Ian Stewart has done it again!, 29 Nov 2008
What more can I say?

Ian Stewart takes us on a journey through group theory to places you probably never considered, but in a completely fun and accessible manner. The historical tone of the book works really well, this book has inspired me to study galois theory in far greater depth.

A MUST for anybody with an interest in mathematics.

Algebra HELP!, 14 Nov 2005
I've just started a university course that i needed a little element of Algebra to make certain calculations

This book explains topics very well. The only things which i think it lacks is having questions that the reader can work through to improve their own skills.

Great book, but only good for reference/understanding.

Sadly, not a book for everyone, 25 Jun 2007
Really interesting book which puts currently taught mathematics into its historical context. I bought the hardback which has "even algebraphobes will struggle to find fault" - don't believe a word of it: I don't think I would have understood much of the book without having done first year university pure maths already and would not recommend it to non math-inclined friends. There were a few typos in my edition but not enough to cause too many problems.

A Rollercoaster ride through the history of algebra... Hold on tight!, 05 Jul 2006
I've long been interested in the history of science and mathematics and have to say that this book is an absolute treat to read.

I read John Derbyshire's other historical mathematics book - "Prime Obsession" - about a year ago and was mightly impressed. His ability to weave historical facts with some of the more complicated mathematics is something that a lesser author would stumble with. Not Derbyshire. "Unknown Quantity" takes "Prime Obsession" further - as it were - leaving behind one specific area of mathematical intregue (the Reimann Hypothesis) and covering this time the entire field of the history and development of algebra. Its a interesting feat to attempt given the huge subject base and the literally hundreds (if not few thousands) of years of history that have to be covered, but he does it well. Along the way we encounter ALL of the big names in maths: Galois, Lagrange, Euler (to name but a few) and some others that you may not have heard of, all of them though have their own backstories that make the characters come alive on the page (it is amazing how often some form of tragedy befalls a member of the mathematical elite of the 18th and 19th centuries).

Cracking collection of rings, 25 Jul 2008
Far better than the 500 pendant/lockets book from Lark, following the matrimonial theme having a high wearability factor of the rings shown, not all WED's and some good inspirational Engagement rings too. A great source book of ideas for any Jeweller or collector wanting to create a greater spectrum of rings. I keep thumbing through this book and see something different every time, excellent pieces of work front to back.
The book its self is paperback, of good quality colour images, laid out with 1-2 photos a page with a brief description of who, what with, why, size description accompanying the photo with the front and back covers having flaps to use as bookmarks.

beautiful, 31 Jan 2008
I have most of the lark jewellery series they have done - 1000 rings, 500 necklaces, 500 earrings etc. I don't have 500 bracelets because it wasn't up to standard and I haven't yet seen 500 brooches.
Anyway, this addition to the series is a success! Its a gorgeous book of rings, some more matrimonial than others, but all stunning. I think that there is a higher "wearability" factor with this rings book too. In 1000 rings, which was one of my fave's, the rings where whacky and some outlandish but still brilliant and inspiring. This book has a different class of ring. I still need to page through it and absorb them all but its very very inspiring for jewellers or collectors etc. This is a beautiful collection with many styles to see. As with all these coffee table types books lark have done, it is not a project book. Its a gathering of amazing work presented as a gallery - so is good as inspiration etc. Brilliant, I'm very pleased with this one. There is probably a lot more in this book that can really be worn by people. Some have commented that it doesn't really seem like a collection of "wedding" rings, as the title implies - but I think it is. There are some that would be more quirky, but this definately broadens the wedding band or engagement ring spectrum! I can see these as wedding rings or normal beautiful rings - whichever you prefer! If you like any of the other lark 500 books, I feel that you will really like this one.

This book helps consolidate your knowldege of basic algebra, 29 Dec 1999
This small volume provides you with carefully worked out examples and plenty of problems to solve (answers at the end of the book). It assumes some understanding of algebra and is not for absolute beginners. By the time you have worked through the chapters, you are likely to be proficient in the topics under discussion. I will recommend it to anyone trying to learn basic algebra without the help of a tutor.

Good Book, 12 Sep 2007
If you want to solve lots of exercises this is a good choice. Of course, exercises are important to master this topics, but I advice you to get a good calculus (or vector calculus) book to understand theory. I think shaum's vector analysis is a bit incomplete on that matter. Well... it's a shaum's outline series...
I found this book useful, especially for electromagnetics. I'm happy to own it.

I love these Schaum's books!, 17 Nov 2000
As with all the Schaum's books, it's packed with all the theory you could possibly need to know (for a basic vector analysis course). Add this to enough worked examples and supplementary problems to shake a big stick at and you've got one brilliant book.

Put it this way, the first time I sat my vector course at uni I got 3%. I bought this book, resat, and got 87%. Enough said.

The introduction to tensors is quite basic, but if you want a book on tensors then buy the Schaum's Tensor Calculus one 'cause it's great too!

What a little gem of a book!, 24 Dec 2007
A perfect book! My 11 year old daughter was entranced by the 1089 problem, and would be reading the book now, except I gave our copy to a friend, (have just ordered another three for us and any other casual callers). I'm doing a maths PhD and I loved it, and have learned things from it. Each chapter leads through a new idea, entertainingly written, but also, for example, giving a clear andsimple introductory explanation of calculus. I think all maths teachers should be given a copy, and should use it in class! Also explains what maths can do, what's it FOR! Absolutely recommended for maths lovers and maths-phobes alike.

Perfect for lecturers, teachers, students, pupils and those with just a vague interest, 17 Oct 2007
Alarmed at how much of my children's maths lessons was being lost to determining who had thrown this or that piece of paper, I sought a source of inspiration to keep their love of mathematics alive. I have found it. "1089 and all that" is perfect for the job.

Do not think that this is a book aimed at children, though, it is suitable for everyone, including lecturers and will be of benefit to many. First year students obliged to take a maths course will find many stimulating thoughts, though they should read the book with caution, they might just find themselves wanting to major in maths. Such late discovery of the joys of maths could be avoided by presenting all maths and physics teachers with their personal copy to enable them to liven up their classes with interesting asides, I suspect that, if only he could be motivated to do so, Acheson could inspire the least interested slob to stop throwing trajectiles and study their motion instead.

I had imagined that the task of building up my children's flagging interest might be slightly forced, even once I'd identified a suitable book, but I couldn't have been more wrong. Just a quick look at the first few pages on-line sent my sons charging off to tell their friends to "Think of a three digit number..." And now that it has arrived, I am redundant, because David Acheson's little hardback, does a far better job than I could ever do. Clear text, amusing cartoons, diagrams, and even blackboard look alikes, every page is a feast. "1089 and all that" is a book that you could race through, but you probably won't because you will wish to savour every tasty morsel of this cordon bleu fare.

Smashing!, 16 Oct 2005
A great little book, which makes mathematics accessible to anyone who wants to know. Written in a really friendly, non-condescending manner; Acheson wants you to like his subject, but takes great care not to force it upon you. Recommended for mathematicians looking for a spot of light relief, and non-mathematicians who just want to know a little bit more.

Interesting and concise, 21 Jun 2004
I had the pleasure of attending a summer school at Oxford where the maths lectures were taken by David Acheson. On the back of that, I bought this book and I'm glad I did! It's interesting and manages to explain things without patronizing those readers with mathematical knowledge, and yet helps those with very little. Highly recommended!

A fascinating little book!, 20 Mar 2004
I am currently training to be a maths teacher, and bought this book largely out of curiosity. But what a great little book! It is written in a style that is understandable to anyone without a great deal of mathematical knowledge, but is still interesting to anyone with a maths background. The style is lively and entertaining, and there are plenty of pictures and diagrams. Chapters such as 'The Trouble with Algebra', 'On being as Small as Possible', 'Are We Nearly There?', 'What is the secret of All Life', and 'Not Quite the Indian Rope Trick' introduce topics such as algebra, geometry, caluculus, infinity and far, far more. It has lots of fascinating little snippits that appealed not only to me, but also to my husband (who is not a mathematician), and my 13 year-old son. A lovely little book!

Ian Stewart has done it again!, 29 Nov 2008
What more can I say?

Ian Stewart takes us on a journey through group theory to places you probably never considered, but in a completely fun and accessible manner. The historical tone of the book works really well, this book has inspired me to study galois theory in far greater depth.

A MUST for anybody with an interest in mathematics.

Algebra HELP!, 14 Nov 2005
I've just started a university course that i needed a little element of Algebra to make certain calculations

This book explains topics very well. The only things which i think it lacks is having questions that the reader can work through to improve their own skills.

Great book, but only good for reference/understanding.

Sadly, not a book for everyone, 25 Jun 2007
Really interesting book which puts currently taught mathematics into its historical context. I bought the hardback which has "even algebraphobes will struggle to find fault" - don't believe a word of it: I don't think I would have understood much of the book without having done first year university pure maths already and would not recommend it to non math-inclined friends. There were a few typos in my edition but not enough to cause too many problems.

A Rollercoaster ride through the history of algebra... Hold on tight!, 05 Jul 2006
I've long been interested in the history of science and mathematics and have to say that this book is an absolute treat to read.

I read John Derbyshire's other historical mathematics book - "Prime Obsession" - about a year ago and was mightly impressed. His ability to weave historical facts with some of the more complicated mathematics is something that a lesser author would stumble with. Not Derbyshire. "Unknown Quantity" takes "Prime Obsession" further - as it were - leaving behind one specific area of mathematical intregue (the Reimann Hypothesis) and covering this time the entire field of the history and development of algebra. Its a interesting feat to attempt given the huge subject base and the literally hundreds (if not few thousands) of years of history that have to be covered, but he does it well. Along the way we encounter ALL of the big names in maths: Galois, Lagrange, Euler (to name but a few) and some others that you may not have heard of, all of them though have their own backstories that make the characters come alive on the page (it is amazing how often some form of tragedy befalls a member of the mathematical elite of the 18th and 19th centuries).

But it's not all history. Derbyshire deftly takes us through some simple examples - how to solve the general cubic equation (and extend this to the general quartic) in a detailed yet unpatronising way - and goes further into some of the more abstract areas of modern mathematics (fields, algebras and manifolds).

This is a fabulous book that takes us from ancient civilisations in the middle-east through europe in the 18th and 19th centuries and out to the present day, and leaves you with a sense of awe at what was achieved and what could yet be discovered in this most intreguing of mathematical fields.

Excellent introduction to medium level algebra, 26 Dec 2007
An excellent intro to medium level algebra. I bought this book (and its companion - algebra 1 for dummies) in order to be able to help our teenage daugher with her maths. I have no mathematical background beyond an exam when I was 15 - and that was 30 years ago. But the book is clear, user-friendly and easy enough to read at bedtime! Strongly recommended. Ditto for Algebra 1 for dummies and the accompanying workbook.

Best Decision Ever Made, 12 Aug 2007
I was never one for math in school, but when I left into the real world I relaised my math skills needed brushing up on.

All of the 'crap' I learnt in secondary school and forgot every term, or holiday, came straight back to me in seconds because of how well this book is written and layed out.

I am only at chaper 3 so far, and I have just completed a load of basic GSCE online Algebra tests with brilliant results. (BBC BYTESIZE)

I probably sound like i'm selling detergent, but seriously, I owe a lot to this book and Mary Jane is damn fine.

Cracking collection of rings, 25 Jul 2008
Far better than the 500 pendant/lockets book from Lark, following the matrimonial theme having a high wearability factor of the rings shown, not all WED's and some good inspirational Engagement rings too. A great source book of ideas for any Jeweller or collector wanting to create a greater spectrum of rings. I keep thumbing through this book and see something different every time, excellent pieces of work front to back.
The book its self is paperback, of good quality colour images, laid out with 1-2 photos a page with a brief description of who, what with, why, size description accompanying the photo with the front and back covers having flaps to use as bookmarks.

beautiful, 31 Jan 2008
I have most of the lark jewellery series they have done - 1000 rings, 500 necklaces, 500 earrings etc. I don't have 500 bracelets because it wasn't up to standard and I haven't yet seen 500 brooches.
Anyway, this addition to the series is a success! Its a gorgeous book of rings, some more matrimonial than others, but all stunning. I think that there is a higher "wearability" factor with this rings book too. In 1000 rings, which was one of my fave's, the rings where whacky and some outlandish but still brilliant and inspiring. This book has a different class of ring. I still need to page through it and absorb them all but its very very inspiring for jewellers or collectors etc. This is a beautiful collection with many styles to see. As with all these coffee table types books lark have done, it is not a project book. Its a gathering of amazing work presented as a gallery - so is good as inspiration etc. Brilliant, I'm very pleased with this one. There is probably a lot more in this book that can really be worn by people. Some have commented that it doesn't really seem like a collection of "wedding" rings, as the title implies - but I think it is. There are some that would be more quirky, but this definately broadens the wedding band or engagement ring spectrum! I can see these as wedding rings or normal beautiful rings - whichever you prefer! If you like any of the other lark 500 books, I feel that you will really like this one.

This book helps consolidate your knowldege of basic algebra, 29 Dec 1999
This small volume provides you with carefully worked out examples and plenty of problems to solve (answers at the end of the book). It assumes some understanding of algebra and is not for absolute beginners. By the time you have worked through the chapters, you are likely to be proficient in the topics under discussion. I will recommend it to anyone trying to learn basic algebra without the help of a tutor.
