Rent or buy? The challenge of access to housing

...solid and desirable investment. But is this belief well-founded? Figure 4 shows the change in real house prices in the UK over a long period (1979−2017). The prices are shown in real terms, in today’s (2017) money. For example, in 1979, the actual (nominal) average UK house price was only £22,000 but prices of goods and services then were much lower, so that was a...

...solid and enduring worth. It also suggests that she is a national treasure -- that the books she wrote in the front room of a red-brick Georgian house set in a village at the heart of the shires, in deepest, leafiest Hampshire, are so ‘English’ that they can be regarded as being as good as Bank of England gold. The detail of the image is also illuminating. The...

A brief history of the lens

...solid objects. Leonardo da Vinci wrote about the phenomena of light on surfaces, understanding that different intensities of light on a human face vary with the angle that the light strikes; these observations were formalised in the 1700s as a natural law, now used in computer rendering of digital images. Artists have continued to experiment with depicting the world as...

...liquids could save lives...[Virginia Mason Hospital, Seattle] The Virginia Mason Hospital in Seattle In November 2004, Mary McClinton was admitted to Virginia Mason Medical Center in Seattle, USA, to receive treatment for a brain aneurysm, a potentially serious swelling in a blood vessel. What followed was a tragedy, made worse by the fact that it was entirely...

...liquid water ocean underneath the outer ice shell. Further, Galileo also observed a relatively young and crater-free surface, possibly reflecting the exchange of material between the ice shell and an ocean below. It also detected salts on the surface, which could arise from an ocean interacting with rocks at a seafloor, and arc-like surface fractures that appear to...

...liquids and gases, I can grow ices very similar to Enceladus’s, starting with very simple ices and building up to more complex ones. Other processes affect Enceladus. Its surface receives a high level of radiation and its orbit is within Saturn’s E ring, which is made up of millions of tiny grains of dust and ice. These ‘micrometeoroids’ regularly hit the surface....

...solids has been used for centuries, but modern architectural design can enhance all three effects for space heating, hot water supply and heat storage. Such passive solar heating relies on short-wave radiation being absorbed by materials so that they heat up and then slowly re-emit long-wave radiation. The most obvious example is inside a greenhouse, where solar radiation...

...solid. It makes up less than 4 per cent of the Moon's total mass, a much smaller fraction than for any of the other terrestrial planets. This can be explained by computer models of the giant impact in which the Moon was born. These show the core of the impacting body accreting onto the core of the proto-Earth, whereas the Moon formed from the mixture of fragments of the...
