The Eisenhower Tunnel is the longest mountain tunnel in the world, located in the Rocky Mountains of Colorado. It was completed in 1979 and bypasses Loveland Pass. The original spacing was changed in 2007 due to the trucking industry’s request. Seven workers died during its construction. Of the more than 41,000 miles (65,983 km) of […]
A height gauge can measure the height of an object or automatically mark parts at a specific height. There are two main types: Vernier calipers and electronic/digital. They are used in retail, industrial, test, laboratory, and medical environments. They are used to set the height of a desired measurement, saw blades, and other automated tools. […]
Calculating ideal weight for height considers frame size. A midframe measurement can be taken by measuring the distance between the sides of the right elbow when the arm is extended in front of the chest. Ideal weight varies, but for women, 5 pounds should be allotted over 100 pounds for every inch over 5 feet. […]
Weight and height percentile charts are used to track growth rates and overall health in children and young adults up to age 20. Doctors use the charts to compare a child’s growth to others in their age group and make recommendations for care, diet, and exercise. The charts are divided into two different age groups […]
A vernier height gauge is a tool used for precise vertical measurements in metalworking and related industries. It uses a sliding vernier scale to augment a fixed scale for higher measurement resolution. It often has an engraving tool for marking identical measurements and can be adjusted for continued accuracy. Digital height gauges are an alternative […]
In summer, the Eiffel Tower can grow up to 6.75cm due to thermal expansion. It was originally planned for Barcelona and has had over 200 million visitors since its construction. It was the tallest building in the world until 1930. During the summer months, the Eiffel Tower gets a little taller. Thermal expansion generated by […]
Oceanography studies ocean waves and currents, which affect global climate. Significant wave height (Hsig) is the average height of one third of the highest waves during a given time. Hsig is used for graphing, forecasting, and ship design. Changes in global climate have led to a revision of Hsig data. Oceanography is the scientific study […]
Theoretical skyscraper height is limited by wind, elevators, and budget, not structural materials. Counterweights and multiple stems can help with wind, while double-deck elevators and sky lobbies can improve elevator efficiency. Budget is the ultimate limitation, with a 6,500-foot structure potentially costing $10 billion USD. Frank Lloyd Wright’s 1 mile tall tower, The Illinois, was […]
South Koreans are taller and heavier than North Koreans due to better childhood nutrition and access to healthcare. The average height of a North Korean military recruit is 4 feet 6 inches, while the average height of a South Korean college graduate is 5.6 feet. Short stature was once associated with determination in South Korea, […]
Napoleon was not unusually short, but rather an average height for his time, possibly 5’7″. Descriptions of him as smaller were likely due to differences in inches. He was born into a family of minor Italian nobility and was of normal weight in his youth. Historians have often portrayed Napoleon Bonaparte as unusually short, although […]
