Calculus is the key to much of modern science and engineering. It is the mathematical method for the analysis of things that change, and since in the natural world we are surrounded by change, the development of calculus was a huge breakthrough in the history of mathematics. But it is also something of a mathematical adventure, largely because of the way infinity enters at virtually every twist…
Suara George menjadi lebih dalam. Ia mengulangi kata-katanya dengan berirama, seolah ia sudah begitu sering mengucapkan kata-kata ini. "Orang-orang seperti kita, yang bekerja di peternakan, adalah orang-orang paling kesepian di dunia. Mereka tidak punya keluarga. Mereka tidak cocok di tempat mana pun. Mereka datang ke peternakan dan bekerja keras lalu pergi ke kota dan menghamburkan hasil kerja…

The conversation had taken an unexpected turn. It is not often that people compare academic publishing and churchgoing. Nor would many think of using age as a measure of the credibility of an academic journal. Yet Akosua’s witty apercu, offered in an interview about academic publishing practices in Ghana, reveals an important truth. A scholarly journalâ€â€¦
Although (Soddy, Nature 92:399–400,1913)inferred the existence of isotopes early lastcentury, it was not until the discovery of theneutron by (Chadwick, Nature 129:312,1932)that isotopes were understood to result fromdiffering numbers of neutrons in atomicnuclei. (Urey, J Chem Soc 1947:562–581,1947) predicted that different isotopes wouldbehave slightly differently in chemical (andphys…

Long recognized as one of the main branches of political science, political theory has in recent years burgeoned in many different directions. Close textual analysis of historical texts sits alongside more analytical work on the nature and normative grounds of political values. Continental and post-modern influences jostle with ones from economics, history, sociology, and the law. Feminist conc…
Security Sector Reform (SSR) is at a crossroads. SSR concepts and practices are embedded in international efforts to promote peace, security and development. They are widely considered an essential element of many multilateral and bilateral stabilization efforts and are a standard feature of the post-conflict toolkit.1 SSR is routinely commended for the way it can integrate siloe…
Over the past two decades, Canadian international history has slipped its traditional North Atlantic moorings. Studies of Canada’s postwar relation-ships with a waning United Kingdom or an ascendant United States have faded in popularity, replaced with a stream of publications on relations with the decolonized states of Asia, Africa, and the Caribbean, countries whose citizens increasingly co…
Wildfires, often called ‘bushfires’ in Australia, are an annual occurrence in Australia, especially in the southeast. Each year they burn thousands of square kilometres of bushland, blazing everything in their way. Some of the physical infrastructure erected or grown by people, such as fencelines, buildings and crops can be rebuilt and replanted, despite the deva…
