The refugee crisis is destabilising nations

The greatest fear among all the countries involved, however, is about the kind of Syria that will finally emerge from the conflict.

The human cost of the increasingly savage civil war in Syria can be seen in the faces of its displaced children. Some outlined their deeply disturbing stories to me earlier this month at the Zaatari refugee camp in Jordan, where about 60 per cent of the current population of 180,000 is of school age. Boys and girls described experiences that hardened soldiers would find it difficult to cope with, all the while displaying physical and psychological wounds that in many cases will never heal.

That the youngest victims of Syria’s violence are among the best placed to tell us about its wider effects is beyond doubt, but there is a great deal more to be learned from the refugee communities growing on the country’s perimeter. Spend just a few days in camps such as Zaatari – which opened less than a year ago but is now the fourth-largest city in Jordan – and you soon begin to realise that these new settlements threaten to provoke an economic, social and security crisis that could have repercussions as grave as the fighting that created them.

The scale of the refugee problem was made clear by the United Nations recently when it called for a $5.2bn fund to help cope with the flight of men, women and children from Bashar al-Assad’s tyranny. This amounts to the largest appeal of its kind in history. Even that enormous figure might not be enough, as the UN estimates that the number of Syrian refugees across the region – now 1.6 million – could reach 3.5 million by 2014.

Aid workers I spoke to pointed to growing resentment among host populations. Despite the lavish wealth often displayed by Jordan’s monarchy, many of the 6.5 million people living in the country are relatively poor – yet their government is currently accommodating roughly half a million Syrian refugees. Up to 2,000 more arrive every day, putting an immense strain on resources.

While in Jordan, I often saw local people being turned away as they demanded a share of the aid being distributed by charity groups to Syrian newcomers. Water is becoming particularly scarce among Jordanians, who are unhappy about the 35 litres per person each day that the Syrians are using. This is six times more water than the average Jordanian gets through.

Water deliveries are few and far between in towns and villages where crowds took to the streets as recently as December to complain about the high cost of gas and electricity. As summer droughts begin and the lack of water drives up food prices, many believe it could be the catalyst for severe civil unrest.

“It is always economic shortages which trigger the street demonstrations,” said Hind, a teacher who lives close to Zaatari. “Jordan is considered one of the most secure countries in the region but, with more and more Syrians arriving every day, there will be a breaking point. It will be the same in other countries nearby.” Syrian rebels are openly using refugee camps for rest and recuperation. Zaatari is just five miles from the border and an obvious place for combatants to travel to. Armed groups can establish a firm and relatively safe base in a neighbouring country before heading back to the front line. This raises the prospect of conflict proliferating across the region.

Lebanon, which has experienced a 20 per cent increase in its population since the start of the war in Syria in 2011, is the home of Hezbollah militants who are fighting for and alongside President Assad’s troops. Turkey, which is pro-rebel, is sheltering more than 200,000 Syrians. Turkey, like all of Syria’s immediate neighbours, is becoming increasingly fearful of terrorist attacks directly linked to the civil war.

The greatest fear among all the countries involved, however, is about the kind of Syria that will finally emerge from the conflict. It was King Abdullah II of Jordan who, in April, presented President Barack Obama with a map of Jordan’s neighbour divided into rival fiefdoms and – most sinisterly of all – showing its surrounding deserts dotted with terrorist training camps.

The prospect of sectarian hatred and murderous extremism being formalised by new borders is terrifying, especially when one considers the role that ordinary Syrian people played at the start of the Arab spring in 2011. It is easy to forget that it was their street protests demanding change that grew into a nationwide movement – one that was crushed by Assad as he set about massacring his own people.

As many of the surviving protesters find themselves forced abroad, their problems not only remain unresolved but are being exported to countries that are increasingly unable to cope with them.

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.
