1. Are you ready?
The FA Cup final - the biggest day of the national footballing calendar.
The pitch is prepared, the pies are hot, 90,000 fans are seated and 10 million people around the country are tuned in, waiting for kick-off.
What’s the maths behind making this moment happen?

6. When 300,000 went to Wembley
No one knows exactly how many people attended the first Cup final to be held at the newly built Wembley Stadium in 1923.
The official capacity was 126,000, but an estimated 300,000 managed to get into the ground. The crowd surged onto the pitch and famously had to be encouraged back to the touchlines by PC George Scorey, mounted on a white horse called Billie, before the match could start.
Given the numbers inside Wembley there were remarkably few serious injuries, but the events triggered a Parliamentary inquiry – the Shortt Report. It was one of the first times maths was used to model crowd safety at football stadiums.
Many features that are now commonplace at matches were first proposed in this report, such as all-ticketed matches, stewards, a minimum number of turnstiles per thousand capacity, and regularly spaced vertical and horizontal gangways.
The White Horse bridge leading to the new Wembley Stadium was named in Billie’s honour.
PC Scorey was awarded tickets to subsequent Cup finals in gratitude, however he was reportedly not interested in football and chose not to attend!
7. Safely home
Win, lose or draw – how maths helps everyone to get home safely
Dr G Keith Still, professor of crowd science at Manchester Metropolitan University, who spent three years studying crowds at Wembley stadium, talks through some of the basics.
