Technology – Environmental Protection and Consumption As resources become scarce and ecological destruction increases, methods to reduce consumption, and improve technology to protect the environment become increasingly necessary for ourselves and our children. The high rate of consumption of raw materials, such as petroleum and metals, will cause a shortage of raw materials in the … Read more

Discovery Science: Manufacturing Technology – Industrial Engineering

Manufacturing Technology – Industrial Engineering The central phase of the production process is manufacturing. Manufacturing is the point at which products are produced in their final form from raw materials and/or component parts. Up until the 18th century, all processing of raw materials was done by hand or with the aid of hand tools. The … Read more

Discovery Science: Technology – the Production Process

Technology – Manufacturing Technology In this era of globalization, rarely is a product completely manufactured in a single location. Information networks are intricately tied with international production systems. Many simple components are manufactured in multiple locations around the world and then assembled in another location to make a final product, such as a computer, an … Read more

Discovery Science: Construction – Bridges and Dams

Construction – Bridges and Dams Bridges, dikes, and dams are among the most demanding challenges of structural engineering. They are often subject to extreme and variable forces from tides, winds, or moving masses of snow and earth. Bridges are built to span rivers, valleys, and crossroads. All possess a horizontal span and a means of … Read more

Discovery Science: Technology – Roads and Tunnels

Physics and Technology – Technology – Roads and Tunnels Civil engineering includes the construction of roads, tunnels, canals, dams, and bridges. A deciding factor in design is the stability of the geological subsoil in the area. Roads have to be strong enough to withstand the load of heavy traffic for several decades. Roadways are subjected … Read more

Discovery Science: Energy – Efficient Construction

Construction – Energy – Efficient Construction The oil crisis of 1973-1974 exposed the delicate balance between the rising demand for energy and the Earth’s limited resources. Today energy-efficient construction is an essential, expanding area of building technology. Land values can be a decisive factor in construction plans: high square-feet costs often lead developers to build … Read more
