No two histories are the same size. Some are so tiny that you can nestle them in your hand, their translucent pages fluttering with your breath. Others range over many volumes, challenging the strength of your grip with the combined weight of their leather covers, rag paper pages and glassine illustration protectors. Some hold us enthralled with split-second events in tiny places, othe…
In this chapter we present the foundations of Newton’s theory of gravitation. Intuitively, the theory of gravitation is easiest to understand as “action at a distance,” Latin actio ad distans, where the force between two masses is proportional to the masses themselves, and inversely proportional to the square of the distance between them. This is the form of Newton’s general law of grav…
In traditional societies, undoubtedly the most common conception of the figure of the Earth was that the Earth is a flat disc extending to the horizon, with the sky curving like a dome over her. On the inner surface of the dome, the celestial bodies describe their complicated orbits. Children also have generally the same conception. Only with formal education does this “naïve world model” …
Governing is the art of planning and predicting. Developing a picture of long-term jobs and skills requirements is critical for policymakers as they navigate rapid, complex and uncertain shifts in the economy and society. A wide range of areas – from curriculum development and careers guidance through apprenticeships and workplace training to occupational standards, migration and social insur…
Fifteen to twenty billion years ago, the universe arose as a cataclysmic eruption of hot, energy-rich subatomic particles. Within seconds, the simplest elements (hydrogen and helium) were formed. As the universe expanded and cooled, material condensed under the influence of gravity to form stars. Some stars became enormous and then exploded as supernovae, releasing the energy needed to fuse sim…
Across the world, fisheries provide direct employment for around 38.982million people (Food and Agriculture Organization [FAO], 2020). In many coastal regions of the world, and particularly in many low-income contexts, fishing livelihoods remain the primary economic activity. Globally, they make significant contributions towards food and nutrition security, and are …
The most comprehensive systematic transreligious theology is presented in Robert Cummings Neville’s three-volume Philosophical Theology. The first volume is called Ultimates and contains a précis of the whole. Neville establishes a metaphysical structure within which the various “ultimates” represented by or symbolized through various traditions find their place. His accomplishment, requ…
Luas hutan mangrove Indonesia sekitar 3 juta hektar yang mewakili 23 % keseluruhan ekosistem mangrove dunia. Kita kehilangan hampir separuh dari luas mangrove dalam tiga dekade terakhir. Lamun (sea grass) dan terumbu karang (coral reef) mengalami hal yang sama. Ini adalah potret bahwa pesisir Indonesia sepanjang 95.000 km sangatlah rentan terhadap kerusakan lingkungan. Perkembangan penduduk yan…
In this chapter you will look closely at what automatic controls are supposed to do. The elements necessary to provide control are presented. These are often arranged by how they control, either open loop or closeed loop. Examples of each are given. Control systems are also classified by what they control. Servomechanism control systems (control of movement) and process control systems (control…
