Sense of hearing. Animation showing how sound waves produce the sensation of hearing. Sound waves enter the ear canal, and cause vibrations in the eardrum (tympanic membrane), which separates the middle and inner ear. The eardrum is connected to the ossicles, a system of three tiny articulated bones that transmit the vibrations from the eardrum to the fluid-filled cochlea (coiled) in the inner ear. The cochlea contains the organ of corti, which contains rows of hair cells topped with stereocilia. The stereocilia detect tiny movements in the fluid, which are translated into nerve impulses. These travel to the brain, where they are deciphered as sound.

Animation of the structures of the inner ear. The view zooms in to the side of the head to show the eardrum, or tympanum (dark red disc). This is connected to the cochlea (spiral shape) by the tympanic cavity. In this space, three tiny bones (not seen) pass the vibrations of the eardrum to the cochlea. The cochlea is a spiral fluid-filled tube lined with nerves. Sound information conveyed by the bones causes pressure waves in the liquid which are detected by the cochlear nerves, which are processed by the brain to produce the sense of hearing. Above the cochlea are three semicircular canals, which also contain fluid and nerves and are responsible for balance and positional sense.

Marching band at Houston astronaut parade, August 1969. Footage of a marching band at the Houston astronaut parade of 16 August 1969 in Houston, Texas, USA. This parade was held to honour the Apollo 11 astronauts. Three US astronauts (Neil Armstrong, Edwin 'Buzz' Aldrin, Michael Collins) had achieved the first landing by humans on the Moon on 20 July 1969 as part of NASA's Apollo 11 mission (16-24 July 1969). Over the following months, the Apollo 11 astronauts took part in numerous national and worldwide tours to mark their historic achievement. Houston is the home of NASA's mission control, the Manned Spacecraft Centre (MSC), and this was among the first parades held in their honour. It featured Boy Scouts, a bagpipe band, the Apollo Queens drill team, military bands, and cheerleaders. As well as the Apollo 11 astronauts, other NASA astronauts and their families paraded in cars past the public. Around 300,000 people lined the streets, with a ticker tape parade held along the downtown Houston section of the route. This footage is from the ticker tape parade section of the route, just before the Apollo astronauts appear (banner seen at end of clip).

High-speed footage of coloured paint jumping on a drum skin. The sound of a drum is generated by the vibrations of its tightly-stretched skin. These vibrations are hard to discern with the naked eye, but the addition of liquid paint to the skin surface reveals the movement.

Coal-fired power station. Animated diagram showing the main parts of a coal-fired power station. Coal is held in storage (left) until needed, then is pulverised to form a thick dust. This is blown into the boiler (centre) where it burns at high temperature, releasing smoke and carbon dioxide into the air (upper left). This heats water in pipes and turns it into steam. The steam is fed through successive stages of turbines to extract the maximum energy, turning generators that produce electricity. The water is recondensed then cooled in a cooling tower, before returning to the cycle.
