Misoriented interphase boundary between h-BN and SiC grains
The micrograph shows misoriented interphase boundary between h-BN (precipitate) and SiC grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react wit
Where U.S. Politics Came From
John Green discussed where American politicians come from. In the beginning, soon after the U.S. Constitution was adopted, politics were pretty non-existent. George Washington was elected president with no opposition, everything was new and exciting, and everyone just got along. For several months, anyway. (13:57)
The Market Doesn’t Solve Problems; People Do It is wrongly accepted by many liberals (i.e., libertarians) that most, if not all, social problems can be “solved by the market.” But clearly, the “market” cannot magically solve our problems. Let it be clear that there is no doubt that the best way to have social progress is to have a free market economy. However, free markets are not solutions to problems, per se, but are rather what gives us the opportunity to find our own solutions to our own problems by finding t
4.3 Physical grounds for thinking we are immortal In section III Hume discusses what he calls physical reasons for thinking there is an afterlife. A sensible guess as to what he means by a physical reason is that it is one based on observation and experience of the physical world. He begins by asserting that physical reasons are the ones he has most respect for. (This assertion is unsurprising: his objections to moral reasons, and the metaphysical reasons we skipped, turn on the allegation that they depend on claims that go beyond wha
2 Creationism in disguise In recent years, creationists have re-branded their hypothesis as 'intelligent design', which asserts that the apparently designed fit of organisms to their conditions of life necessarily implies the existence of an intelligent designer. This idea is no more than the old 'argument from design', promulgated most famously by William Paley in his fable of chancing upon a watch and inferring a watchmaker, which the theory of evolution by natural selection refutes, as brilliantly explained by Rich

Ocean Acidification Symposium - The metal isotope toolbox: a case study in the Southern Ocean
The Ocean Acidification Symposium was presented by the Centre for Chemical and Physical Oceanography, in November of 2012. The day-long symposium featured brief presentations from a wide range of researchers, of which this is one: Dr Melanie Gault-Ringold explores the role of bioactive metals in the lives of southern Ocean phytoplankton. This talk looks at the role of cadmium and other metals, and how southern ocean phytoplankton differ form their northern cousins

An understanding of ecology is important to inform environmental decision-making. Soil pH influences the availability of mineral nutrients to plants and hence the distribution of different plant species. Some species may be classified as either calcicoles or calcifuges. Variation in salinity, exposure to desiccation and biotic interactions (e.g. grazing) influence the zona Towards Evidence-based Practice in Science Education (EPSE) - an ESRC funded Teaching and Learning R 1.2.3 Pie charts: Nuclear power stations

Over the last three decades major events, scandals and regulations have shocked the pension system. Have the public lost faith in occupational and private pensions? Should the state pension be enough to see us through our old age? And with the non-working to working ratio continuing to rapidly increase, who will pay? We hear from those that were directly affected by the scandals of the 90's and the collapse in private pensions since - and from the experts whose job it is to help us make provisi
