In Britain, the Glastonbury Canal is believed to be the first post-Roman canal and was built in the middle of the 10th century to link the River Brue at Northover with Glastonbury Abbey, a distance of about 1.75 kilometres (1,900 yd).
A. Yes, but not in detail. âMany scientists use electron, scanning tunneling and atomic force microscopes to view individual DNA molecules,â said Michael W. Davidson, curator of the National High Magnetic Field Laboratory at Florida State University.
Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing large objects that are visible to the naked eye at low magnifications (under 50x). A stereo microscope provides an upright and unreversed, 3-dimensional image of the specimen. A compound microscope, also known as high power or biological microscopes are used to view micro specimens that are not visible to the naked eye at high magnifications (40x-1,000x). A compound microscope provides an inverted 2-dimensional (flat) image of the specimen.
