The research has come at an interesting time as Big Ben is about to fall silent for the first time in 30 years as major restoration work takes place. And although when we hear the bell toll we perceive it to be a single sound it is actually made up of a series of distinct frequencies – layered pulsations happening at the same time. Using ‘laser Doppler vibromety’, a 3D computer model and lasers to map the vibrations as the bells chimed at 9, 10, 11 and 12 o’clock, the team were able to characterise the distinct sound and map the vibrations in the metal of Big Ben that are too tiny to be seen by the naked eye. And the results? As it is thicker and weighs more than other bells of a similar size, the result is a higher pitch than would normally be expected for its diameter. Now, for the first time ever, a University of Leicester team has been given special access to measure the vibrations of the famous bells for a new BBC Four documentary, Sound Waves: The Symphony of Physics. It’s the centrepiece of the London skyline, the Elizabeth Tower, fondly known as Big Ben, which has been keeping Londoners on time with its distinct hourly bong for over 150 years.

Early in the game you can jump into a turbo plane with which you can fly around but you can't touch the platforms, except for the landing pads which are necessary as you have limited fuel and your plane flashes red when you are low. Patrolling the entire area are helicopters that follow random routes around the platforms and must be avoided. Gaps can be jumped over, but you can fall from any height, and low spaces can be traversed with up or down sticks and green buttons that send you to the platform above. You must navigate platforms, some of which move and some of which open and close, while avoiding obstacles that are deadly to the touch. An evil wizard named Jem has trapped you in the complex and will only let you escape if you ring the bell of Big Ben sealed by a tunnel that can only be opened once 30 gold coins have been collected.
Big Ben is a platformer in which the screen scrolls in multiple directions as you move your hero, Giz, while trying to escape from a Space Complex.
