I have many interests - I'm a photographer, hill-walker, engineer, ergonomist, author, bellringer and more besides. For many years I have shared my interests with clubs and groups by giving talks on a wide range of topics.
If you are not too far from Wokingham, and interested in a talk, then contact me. See the sort of groups I have spoken to .
English style bellringing is part of our cultural heritage, and is a sound familiar to us all. It originated in England around 400 years ago and has spread to many parts of the world. Ringing requires skill, dedication and teamwork, from people who are normally invisible to their audience. This talk gives an insight into this hidden, but fascinating, world. I adapt the emphasis of the talk to suit the audience (more on history for historians, more on music for musicians, more on maths for mathematicians, and so on). I have been a ringer since my teens, and I have been actively involved in training ringers at local, regional and national level. I have published several books, including "Ringing Skills", and the most comprehensive reference work "The Tower Handbook". For eight years I wrote a monthly column "The Learning Curve" in "The Ringing World". I ring at All Saints Wokingham. See also my talk on the history of ringing in Wokingham . [Back to top]
In this talk for non ringers, I explain how English style ringing evolved, how bells work, and the music of change ringing,
with glimpses into the world of ringers and the fascination that ringing can offer. I vary the talk to suit the needs of the
groups I am talking to. It can be anything from a 20 minute after dinner talk to a full evening's illustrated presentation.

That is an apt description of the tradition of English-style bellringing, which began around 1600 and thrives today. It is also the title of my book on the history of ringing in Wokingham . Unlike my general talk on bellringing , this talk is a social history, looking at the lives and times of ringers in an English market town. The talk takes the same 300-year time-span as the book (the period since the oldest of the current bells were installed). It looks at the 18th century when ringing was a public sport, at Victorian reform of both the church and ringers, and at the 20th century when the band evolved through the trials of two world wars, and into the modern era. It draws on extensive research, to show how the ringers related both to the community around them, and to the church whose bells they rang. The talk lifts the lid on the very special, fascinating, but largely hidden, world of the men and women who kept alive this ancient art in an English market town. [Back to top]
This is the story of England's most spectacular main line railway. Born out of inter company rivalry, the line is a superb example of Victorian engineering achievement, and was driven through the most hostile but beautiful terrain. In the 1980s British Rail's controversial attempts to close the line resulted in the largest public reaction to any rail closure proposal ever. The line now serves commuters as well providing an artery into the Dales for tourists. It is also a heavily used strategic freight route. The talk brings you glimpses of the line's past and recent history, gathered over many years. The talk looks at the line's spectacular viaducts and how they were built, and also at its magnificent surroundings, and the challenging terrain through which the Midland Railway forged a route for its prestige service from London to Scotland. (See also the famous Ribblehead Viaduct knitted in a sweater) [Back to top]
Brick-work is all around us - we take it for granted - but look more closely and you can see a wealth of fascinating detail. Through the centuries, brick-work has been influenced by changing needs, by improved technology and by passing fashions. In the talk, I show you how with simple observation of the brickwork, you can read the stories that are written in the buildings all around us. The talk is illustrated with slides, and I normally bring some samples from my collection of different types of brick – you'll be surprised how varied they are. [Back to top]
lIceland sits just below the Arctic Circle, and astride the mid Atlantic ridge, which divides European from North American at the boundary of their tectonic plates. The plates move apart at about an inch a year, which is why Iceland is very active in terms of volcanic eruptions, most of which never make the headlines. This unique situation gives it amazing geology, scenery, wildlife and culture. My wife and I first visited Iceland in 1991 and we have returned many times since. I will give you glimpses of this fascinating and very special country. (See also Iceland Links.) [Back to top]
The Pennine Way was one of the first long distance footpaths to be created in Britain. It is also the longest cross-country route (only the Southwest Coast Path is longer). The Way passes through some of the finest scenery in Northern England. I walked the route with my wife in 1970 and revisited the area later to complete a photographic essay. Much of the walk is on the hills, but it also crosses valley after valley giving fascinating tastes of the different communities through which the Way passes. (See also Pennine Way). [Back to top]
This draws on a lifetime of hill walking with a camera to bring you a pictorial anthology of hills and mountains. As well as enjoying the superb upland scenery, you will see how geology and civilisation have influenced the landscape, and how a walker can make the best of the resulting terrain. (See also Fell walking) [Back to top]
Have you ever wondered why there is so much pattern in the world around us and why our brains invent it even if it isn't there? Have you ever wondered why illusions work, or why you sometimes make 'silly' mistakes? It's wired into the human brain. Being prone to illusions, and being error prone are the price we pay for being able to survive in an uncertain, complex world. This talk will give you new insights into your perceptual senses with many examples of illusions and paradoxes. An engineering career, artistic hobbies and a lifelong scientific curiosity have gone into this fascinating talk spanning many disciplines. [Back to top]
The discipline of Ergonomics (aka Human Factors) has come to prominence during the last half century, and it plays an increasingly vital role in ensuring that our ever more complex and technological world is fit for the humans who live and work in it. In this short talk, I will give you some insights into the history and current practice of this fascinating subject, which spans the divide between people and their environment (notably the technology on which they increasingly rely) as well as the divide between the so-called 'hard' and 'soft' sciences. To illustrate the problems, I will describe examples drawn from real life, from every day objects to major disasters. [Back to top]
Footpaths are as old as civilisation. They evolve to meet human needs, and most have an organic form that grows and changes without any planning. This is especially so for upland footpaths, which provide vital arteries for walkers, and enable us to enjoy wild places. But in many areas they are becoming an endangered species. Paths came into being because of human use, and they move or disappear when human use changes. Some are very old, but as walkers take to the hills in ever greater numbers, many paths are suffering from over-use, and consequent degradation. Some pleasant grassy paths that I walked in the '60s and '70s have turned into ugly rock-strewn scars on the hillside, under the relentless pressure of millions of boots. Some of this damage is being repaired by bodies like the National Trust and the National Parks, but it is a never-ending task. I have observed paths for many years in all sorts of terrain, in the UK and abroad, seeing how they respond to both use and mis-use. This talk will be a pictorial essay showing the diversity, as well as the fragility, of a very 'natural', but at the same time man-made, upland phenomenon. [Back to top]
My garden and
I have been together for over thirty years. The garden now bears little resemblance to what was there before – it has
more diversity and year-round interest. Yet there were no grand schemes and no dramatic make-overs – just a slow evolution,
motivated by an underlying desire to enrich it. Many changes were opportunistic rather than premeditated. I try to work with
the garden rather than fighting against it. This talk describes how the garden evolved, and why. It is illustrated with many
pictures taken in different seasons over the years. [Back to top]
The talks below are directed at people with a particular interest in topics such as music, maths or technology. Each talk uncovers rich detail, of which many people are unaware.
English-style bellringing is a very special kind of music. It shares some features with minimalism, but it is based on quite different principles, and requires very different performance skills. This talk explains the intricacies of change ringing from a musical perspective. This talk was first given to a group of experienced musicians, as a result of which I was asked to write a series of articles . [Back to top]
All forms of music show some mathematical structure in scales, chords and rhythm. English-style change-ringing is a very special type of music. It has no chords and no variation in rhythm, but it is underpinned by some elegant and fascinating mathematics. The continually changing sequences that constitute the music use what mathematicians call permutative group theory, which also appears in areas as diverse as cryptography and the solutions to Rubik’s Cube. The principles of group theory were formalised in the 19th century, but ringers were using them 200 years earlier without being aware of it. This talk explains the mathematical principles behind change ringing. They flow from the physical constraints on a swinging bell, from the desire for patterns that can be executed from memory, and from the concept of ‘truth’, which is unique to change ringing. The talk concludes with an explanation of the models that I built in 1968. This talk was first given to the Wokingham U3A Maths Group, You don't need a strong mathematical background to enjoy it. [Back to top]
Most people don't realise that behind the familiar sound of English style bell ringing there is a special way of hanging bells so that they can swing full circle. While the physics of a swinging bell are simple, to create a precision musical instrument that responds sensitively to the needs of its performer presents considerable engineering challenges, especially when the instrument may weigh a ton or more. I introduce this talk by explaining how ringing works, and then describe the different parts of a ringing installation, and the technology on which they rely. I describe the way ringing technology has evolved over many centuries, and continues to evolve in the 21st century, with the use of novel materials and new techniques.
There is a shorter, less technical, version of this talk for general audiences, focusing on the evolution aspects. [Back to top]
The sea surface may
appear complex and chaotic, but it is subject to the laws of physics, and many aspects of its behaviour can be explained and
predicted mathematically. This talk gives an overview of how sea waves form, and how they respond to wind, gravity and water
depth. It looks at storms and swells, at 'killer waves' and the Severn Bore. The
talk includes work that I did during the 1960s, some of the results of which I have replicated, and it is illustrated with
lots of photographs and diagrams, as well as some equations. The talk was first given to the Wokingham
U3A Maths Group, and is aimed at those with a general interest in maths, rather than at specialists. I can adapt it to
suit the needs of the audience.
The talks above originated in response to particular requests. Several other potential talks are in my head, but I haven't got round to preparing them because no one has yet asked for them. So if one of the topics below catches your fancy, try asking me. [Back to top]
For several years while our children were young, I spent a significant part of my holidays doing metal sculpture, casting in bronze and aluminium, and welding in steel. I started with no prior experience, and managed to produce an interesting collection of objects that adorn our home. If you are curious to know about different types of artistic casting, and what is enigmatically known as 'found' sculpture, I will explain. You will also hear the experiences of a novice working under considerable time pressure, and of course you will see some of the results. (See also Metal sculpture) [Back to top]
Pennine hills contain some of Northern England's most beautiful scenery. Rugged moorland is crossed by a succession of valleys,
each slightly different in character, and threaded with urban and rural settlements that portray much of the nation's industrial
growth in recent centuries. I grew up on the edge of the Pennines and I have revisited them many times since. In an area larger
than Wales, but perhaps less well known, there is much to tempt the photographer. [Back to
