Ultraviolet

Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 400 nm (750 THz) to 10 nm (30 PHz), shorter than that of visible light but longer than X-rays. Though usually invisible, under some conditions children and young adults can see ultraviolet down to wavelengths of about 310 nm, and people with aphakia (missing lens) can also see some UV wavelengths. Near-UV is visible to some insects and birds.

UV radiation is present in sunlight, and also produced by electric arcs and specialized lights such as mercury-vapor lamps, tanning lamps, and black lights. Although lacking the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions, and causes many substances to glow or fluoresce. Consequently, biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.

Suntan, freckling and sunburn are familiar effects of over-exposure, along with higher risk of skin cancer. Living things on dry land would be severely damaged by ultraviolet radiation from the sun if most of it were not filtered out by the Earth's atmosphere, particularly the ozone layer. More-energetic, shorter-wavelength "extreme" UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground. Ultraviolet is also responsible for the formation of bone-strengthening vitamin D in most land vertebrates, including humans. The UV spectrum thus has effects both beneficial and harmful to human health.

Description

Billed as the first multi-sensory restaurant in the world, Ultraviolet uses sight, sound and smell to enhance the food through a controlled and tailored atmosphere. The restaurant has a single table of 10 seats and serves a single 20+ course dinner menu for ten guests each night.

The dining room of Ultraviolet is ascetic with no décor, no artifacts, no paintings, and no views. It is a purpose-built room specifically equipped with multi-sensory high-end technology such as dry scent projectors, stage and UV lighting, 360 degree wall projection, table projectors, beam speakers and a multichannel speaker system. Each course of the menu is dressed-up by lights, sounds, music, and /or scents, and enhanced with its own tailored atmosphere to provide context for the dish’s taste.

Detective Sergeant Michael Colefield (Jack Davenport) discovers that his best friend Jack (Stephen Moyer) has gone missing on the night before his wedding. Investigating Jack's disappearance leads Michael into the path of a secret paramilitary vampire hunting organization supported by the British government and the Vatican. Michael learns that Jack has become a vampire. Michael remains devoted to his friend and abhors the brutal methods used by the organization's agents – including Vaughn Rice (Idris Elba) – until he realizes that Jack is lying about his situation and that the vampire hunters are correct in their assessment of the vampires. He allows himself to be recruited by the organization, but he hopes to find a middle ground.
