Anamorphic beam shaping optics are used to transform elliptical laser beams to a round shape - for example before coupling them to single mode optical fibers. Conversely, there are cases where ...
Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies. Instead, they bear the rounded shape of an ellipse, a stretched-out circle. One of the most famous ...
Astronomers call the more massive of the two objects, the primary and the less massive one, the secondary. Why are orbits of planets elliptical in shape? Astronomers call the more massive of the ...
Right angles: round, elliptical and nearly square-shaped droplets. (Courtesy: R Schulman/McMaster University) The shape of a liquid droplet can be controlled precisely by sandwiching it between two ...
Indeed, the virtues of elliptical wings had been articulated by British theorist Frederick Lanchester in 1907. The shape had been chosen for the Spitfire “early on,” Shenstone said ...
The stars that previously followed circular orbits within two relatively thin disks get scattered in all directions and form a puffed-up, roughly football-shaped (elliptical) galaxy. In contrast ...
