Have you ever been to a music festival? Well if you live in the UK, the answer is probably yes. The number of festivals has grown greatly over the last few years and now there are around 200 every summer. So let’s look at the history of four famous festivals.

The Glastonbury Festival is a five-day festival of contemporary(当代的) performing arts held most years in Somerset, in the south-west of England. There are a rock and pop stage, a jazz stage, the Avalon stage, a theatre comedy stage, a cinema tent, a dance tent and a circus(马戏团). The festival started in1970and about 120,000 people go to it every summer.

The Reading Festival is truly world-class with rock and pop bands(乐队) appearing from all over the world, particularly(尤其) the USA. About 80,000 music fans go to Reading every August Bank Holiday. The festival first came to its present site on the banks of the River Thames in Reading in 1971, when it moved from Plumpton in Sussex. It is still on the same site over 47 years later!

WOMAD stands for World of Music, Arts and Dance and was the idea of rock musician Peter Gabriel to promote(宣传) world music. The WOMAD Festival started in 1982 and takes place in July at Charlton Park, near Malmesbury in Wiltshire, and you can see different bands and musicians from all over the world. The festival welcomes over 26, 000 visitors each year.

The one-day Monsters of Rock Festival at the National Bowl in Milton Keynes was first held in 1980 and gave visitors the chance to hear the very best of hard rock and heavy metal. There were no festivals between 1996 and 2003 as a result of changing musical fashions, but now it has returned and grown into a two-day festival with a campsite for the 30,000 people who go there in summer days.

A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.

I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. I didn’t do either well. He later informed me that I was “not athletic”.

The idea that I was “not athletic” stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

The night before my marathon, I dreamt that I couldn’t even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.

Shortly after crossing the start line, my shoe laces became untied. So I stopped to readjust. Not the start I wanted!

At mile 3, I passed a sign: “GO FOR IT, RUNNERS!”

By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

By mile 21, I was starving!

As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.

I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

Determined to be myself, move forward, free of shame and worldly labels, I can now call myself a “marathon winner”.

Every year thousands of people come to the city of Pamplona, in north-eastern Spain, for the opportunity to run for their lives as six fighting bulls are released to charge through the town. There are injuries and deaths every year, but the event is of interest to many people. A paper just published in Science describes the insight the event offers into the psychology of panicked crowds.

That is a useful topic to explore. Arehitects, civil engineers and urban planners must try to work out how people will behave in the event of a disaster like a fire, a flood or a terrorist attack so they can design their creations to avoid potentially deadly collisions (碰撞). Unfortunately, solid information is hard to come by. Daniel Parisi, the paper’s lead author, realised that the Pamplona bull-runs offered the perfect natural experiment.

Dr Parisi and his team went to two different rooftop locations in Pamplona in July 2019, and filmed the runners as the animals were released, Later in the lab, they calculated the speed of the runners, the density (密度) of the crowd, the probability of a runner tripping and falling and the relationship between runner-group density and speed.

Perhaps unsurprisingly, the researchers found that runners picked up speed when the bulls drew near. Less expected was the finding that the speed of individual runners increased with the density of the crowd, which was contrary to a long-held assumption in architectural and urban-design circles that people will slow their pace as group density goes up, in order to lower the risk of a collision, which could lead to a fall and, perhaps, injury or death.

Yet it seems that, in the heat of the moment, people pay little attention to the danger of colliding with each other, and do not slow down. The responsibility therefore falls upon urban designers to work out how best to plan the construction of future tunnels, bridges and other passages that restrict flow. The only option may well be to make them wider.
