    The roar of a waterfall suggests the power of water. Rampaging floodwaters can uproot strong trees and twist railroad tracks. When the power of water is harnessed, however, it can do useful work for humans. 

     Since ancient times, people have put the energy in the flow of water to work. They first made water work for them with the waterwheel, a wheel with paddles around its rim. Flowing water rotated the waterwheel, which in turn ran machinery that was linked to it. Today, new kinds of waterwheels – turbines – spin generators that produce electricity. Electricity from waterturned generators is known as hydroelectricity. 

     By building a dam across a river, the natural upstream water level is elevated and a difference in head is created that can be used to drive turbines and generate electricity. A large upstream reservoir may balance seasonal water flow; rain or melted snow can be stored in the reservoir during the wet season to provide electricity during dry seasons. 

    Waterpower is distributed unevenly among the continents and nations of the world. Europe and North America have developed much of their waterpower. Asia, South America, and Africa have abundant waterpower potential, but while countries such as China and Brazil have become leading hydroelectric producers, much of the waterpower resource on those continents remains undeveloped.

        Tourism cannot be treated in isolation since it embodies all tourism practices in the system they operate in. Thus, tourism is a complex sociocultural, economic, and political phenomenon that touches all levels of society. The investigation of tourism’s role in society, the tourism system’s effects on nature, tourism spaces, objects, practices, relationships, and tourist typologies demand systematic sociological investigations. It is important to consider the whole macro system through its members’ social, political, cultural, and economic interactions. In such a social context, both human and nonhuman actors continuously shape and reshape the tourism system, and the tourism system reshapes these actors’ values, attitudes, and behaviors. 

        Researchers examining the sociology of tourism departed from several theoretical perspectives, blended theory and method, and focused on sociological concepts to understand and explain the different aspects of tourism. This group of scholars has been working within the several cores of sociology (like education, family, economy, development, religion, gender, language, migration, social inequalities, labor, and art) and at the margins of emerging interdisciplinary formations, including those crossing many disciplines such as geography, anthropology, economics, political science, psychology, marketing, communication, women’s studies, history, and cultural studies. The sociology of tourism studies engendered transdisciplinary conversations both in academia and in practice, and the results of these studies have created pragmatic changes in tourism practices, habits, and governance.

        Photo exhibitions are great opportunities for excited and ambitious photographers to showcase their work beyond just the safety of their friends and family. They’re also a stellar opportunity to develop a thicker skin, as your work will be subject to critique, but that’s all part of the territory that comes with getting more exposure as a photographer, which is what all artists should strive for. Beyond that, they’re a great way to advertise yourself as a photographer, both your talents and your availability. Think of it almost as the artist’s equivalent to having a booth at a trade show when you’re selling a product. 

        First-timers to an exhibition will likely find themselves a bit unsure of what to do and somewhat nervous. Here’s a series of surefire tips to make any exhibition a success. Before you do anything else, it’s imperative that you make up your mind about what you’ll be showcasing at your exhibition. You only have two choices, when you think about it: brand-new work that you’ll shoot especially for the exhibition or archival stuff that you’ll just pull out for the exhibition. Also, being creative when finding the exhibition location is as important as the showcase itself.

        It is a universal fact that cinema is a visual medium. Films have the power to overwhelm our senses as well as our minds, subjecting us to a variety of experiences that can range from the sublime to the devastating. Colours play a crucial role in this interesting phenomenon, forming an integral part of the composition of each frame and dictating how the viewer perceives the spectacle on the screen. Apart from the cinematic medium, colours have always been a part of our experience and how we make sense of the vastly nuanced world around us. Although science has definitively explained what colours are in terms of light, they have always mystified artists and philosophers like Arthur Schopenhauer and Ludwig Wittgenstein, who tried to understand their importance in anthropological frameworks. 

        More notably, the famous German poet and artist Johann Wolfgang von Goethe published a seminal exploration of colours in his 1810 work Theory of Colours. In it, he examined how each colour corresponds to various psychological states in the minds of human beings. He wrote, “Light and darkness, brightness and obscurity, or if a more general expression is preferred, light and its absence, are necessary to the production of colour… Colour itself is a degree of darkness.” Goethe’s theories might seem baselessly romantic in the 21st century but the underlying ideas have been implemented by filmmakers and cinematographers to curate the voyeuristic experiences of their audiences. Famed cinematographer Vittorio Storaro has based his artistic vision on Goethe’s work, insisting that colours do have a direct connection to the mind of the viewer.
