The Old Bedford River, photographed from the bridge at Welney, Norfolk (2008); the camera is looking downstream, south-west of the bridge. The Bedford Level experiment was a series of observations carried out along a 6-mile (10 km) length of the Old Bedford River on the Bedford Level of the Cambridgeshire Fens in the United Kingdom during the 19th and early 20th centuries to deny the curvature ...
For example, ships travelling on large bodies of water (such as the ocean) disappear over the horizon progressively, such that the highest part of the ship can still be seen even when lower parts cannot, proportional to distance from the observer. Likewise, in the days of sailing ships, a sailor would climb up a mast to see farther.
To fairly represent the Bedford Level (or other) experiment, there would need to be 1,000 marker poles placed between the two letters T and A in the above diagram and each of the 1,000 marker poles would be 1 mile (1.609 km) apart, given that the Earth is 24,901 miles (40,075 km) in circumference.
Experimental Design Diagram (EDD) is a diagram used in science to design an experiment.This diagram helps to identify the essential components of an experiment. It includes a title, the research hypothesis and null hypothesis, the independent variable, the levels of the independent variable, the number of trials, the dependent variable, the operational definition of the dependent variable and ...
Rowbotham started out as an organiser of an Owenite community at Manea in the Fens, where he formulated his ideas about the Earth.After measuring a lack of curvature on the long straight drainage ditches of the Bedford Levels in his first Bedford Level experiment, he was convinced of the flatness of the Earth and began to lecture on the topic.
Henry Yule Oldham, (14 December 1862 – 14 March 1951) was a teacher and geographer who, in 1901, conducted the definitive version of the Bedford Level experiment, a proof that the Earth is a sphere.
The Bedford Level Corporation (or alternatively the Corporation of the Bedford Level) was founded in England in 1663 to manage the draining of the Fens of East Central England. It formalised the legal status of the Company of Adventurers previously formed by the Duke of Bedford to reclaim 95,000 acres of the Bedford Level.
