Can Wonga lecture on responsible finance?

And more importantly, would you let them do so to your children?

In the 12 months ending in Q3 of 2011, 1 in 364 people became insolvent. To put that into context, the average in the past 25 years was 1 in 1,655.

This is how Conservative MPs Andrew Percy MP and Justin Tomlinson MP chose to open their report on financial education in schools (found on this website), and apt I think it is too, because shocking figures like this ought to move the government to doing something about the deficit of this type of education today.

It has cross-party appeal. When I spoke to Ian Murray MP, the Shadow Minister for Employment Relations, Consumer & Postal Affairs, he agreed that in order to make effective changes to credit and debt issues today, we have to go "right back to the start".

Financial education in schools, he said, should be perceived much like the obligation to deliver sex education:

Where there is better sex education in schools there is less teenage pregnancies. The same with financial education – where there is better exposure to this, earlier on, it should follow that there are fewer problems later on.

It is certainly not before time. When I spoke to Rod McKee, the Head of Financial Capability at ifs School of Finance, he told me:

When I visited a school in Hackney earlier this year, when we set the students a task of researching financial terms on the internet the only one they didn’t need to look up was loan shark! I do not know if this was because of what they see on television or from local knowledge, although my impression was it was the latter.

Derek Twigg MP went a stage further, agreeing that financial education needn’t be limited to school-aged people alone:

Further education colleges should open up more financial education courses for adults. These could be linked up to crisis support by a local authority for when someone approaches a council debt advice service or their MP.

Twigg suggested that there could even be a levy on banks to fund the courses – part of a bank's commitment to outreach and financial education.

I think this would suit public sentiment. Rather than banks themselves delivering what they perceive to be good financial advice and support for youngsters, they be obliged to fund rigorous educational materials, taught by the likes of Rod McKee – whose school is currently the only specialist provider of GCSE, AS and A level equivalent qualifications in personal finance and financial studies - to get a balanced view.

And if I’m correct in thinking this is the public sentiment, I would like to see the response by parents if they were to find out that Wonga, the online payday lender, were delivering financial literacy skills for school children – as their chief executive Errol Damelin has recently made plans to do.

As part of their charm offensive – which has also seen a controversial partnership between them and Medway Citizens' Advice Bureau to survey those at risk of spiralling debt – Wonga intend to do something they describe as "innovative and educational in a digital capacity" that will help "kids … to know what all the credit alternatives are".

As pointed out on this site last month, Wonga find it difficult to maintain the fabrication that they are just lending short-term loans out to "web-savvy young professionals" – for this reason, allowing them to be trusted with creating a balanced financial education for children should stick in the throats of any parent.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
