100,000 years ago, at least six human species inhabited the earth. Today there is just one. Us. Homo sapiens.
How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? What will our world be like in the millennia to come?
Dr Yuval Noah Harari gives us an insights from biology, anthropology, and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities.
Gramsci is Dead: Anarchist Currents in the Newest Social Movements
Gramsci and the concept of hegemony cast a long shadow over radical political theory. Yet how far has this theory got us? Is it still central to feminism, anti-capitalism, anti-racism, anarchism, and other radical social movements today? Unlike previous revolutionary movements, Day argues, most contemporary radical social movements do not strive to take control of the state. Instead, they attempt to develop new forms of self-organisation that can run in parallel with---or as alternatives to---existing forms of social, political, and economic organization. This is to say that they follow a logic of affinity rather than one of hegemony.
The calculation of short circuit currents is a central task for Power System engineers, they are essential parameters for the design of electrical equipment and installations, the operation of power systems and the analysis of outages and faults. Short-circuit Currents gives an overview of the components within power systems with respect to the parameters needed for short circuit current calculation. It also explains how to use a system of symmetrical components to analyse different types of short circuits in power systems.
