postmodernism: Forbidden Grill It is a fundamental property of antennas that the electrical characteristics of an antenna described in the next section, such as gain, radiation pattern, impedance, bandwidth, resonant frequency and polarization, are the same whether the antenna is transmitting orreceiving. For example, the “receiving pattern” (sensitivity as a function of direction) of an antenna when used for reception is identical to the radiation pattern of the antenna when it is driven and functions as a radiator. This is a consequence of the reciprocity theorem of electromagnetics. Therefore in discussions of antenna properties no distinction is usually made between receiving and transmitting terminology, and the antenna can be viewed as either transmitting or receiving, whichever is more convenient. A necessary condition for the aforementioned reciprocity property is that the materials in the antenna and transmission medium are linear and reciprocal. Reciprocal (or bilateral) means that the material has the same response to an electric current or magnetic field in one direction, as it has to the field or current in the opposite direction. Most materials used in antennas meet these conditions, but some microwave antennas use high-tech components such as isolators and circulators, made of nonreciprocal materials such as ferrite or garnet. These can be used to give the antenna a different behavior on receiving than it has on transmitting, which can be useful in applications like radar.
London was built around the River Thames and initially prospered due to its excellent trading links. These days it makes most of its money through its financial businesses, many of which are located in the Docklands and Canary Wharf, towards the east of London. The problem with these areas is that, as well as being located within the floodplain on low-lying ground, they are quite literally surrounded by water, as the words ‘wharf’ and ‘docklands’ may indicate. You might think that this would have sounded alarm bells with city planners and architects – after all, you wouldn’t go building some of the country’s most financially lucrative businesses in places that contain words such as ‘pond’, ‘swamp’ and ‘marsh’ – but apparently not. http://www.floodlondon.com/east-london/

currioddity: This is definitely me. “Another motive for gloom is grandtsanding, for the bearer of bad news is less likely to get shot than to acquire a certain authority that those bringing better or more complicated news won’t. Fire, brimstone and impending apocalypse have always had great success in the pulpit, and the apocalypse is always easier to imagine than the strange circuitous routes to what actually comes next…” Solnit, R.

A new film, The Flood, offers an apocalyptic vision of Britain’s capital city under a huge surge of water coming along the Thames. In what appears, from the trailer, to be a fairly typical example of the British disaster movie genre, the surge overwhelms the Thames Barrier, and causes mass flooding to central London. Westminister is turned into a huge lake, the Millennium Eye becomes a giant water wheel. All good hokum, of course, and according to this BBC article, with little truth to it. A storm surge, tsunami or tidal wave big enough to overtop the Thames Barrier, as the film sugggests, would also be enough to flood large parts of Kent and Essex, and go around the barrier. Indeed, it is the Thames Estuary, further downstream from the Thames Barrier (at Woolwich Reach), to the east of Central London, that would be the most likely victim of any rising water levels or flood events. The real devastation would not be around the City of London, but the towns of Gillingham and Chatham, Dartford, Gravesend, Canvey Island, Southend, the Isle of Sheppey, and the proposed Thames Gateway development. It was the floods of 1953, which cost the lives of 300 people, with extensive flooding to the east of London, such as Canvey Island, that was the impetus for building of the Thames Barrier, though ironically the Thames Barrier is only designed to save central London. Now, plans are being made to construct a flood defence mechanism that might serve the whole of the Thames Estuary. More, inevitably, to follow.
