A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Modern ophthalmic lens making machine. Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek philosophers, and the development of geometrical optics in the Greco-Roman world.
The branches of science, also referred to as scientific fields, scientific disciplines, or just sciences, can be arbitrarily divided into three major groups: The natural sciences ( biology , chemistry , physics , astronomy , and Earth sciences ), which study nature in the broadest sense;
Edmund Scientific Corporation, based in Barrington, New Jersey, was founded in 1942 as a retailer of surplus optical parts like lenses. It later branched out into complete systems like telescopes and microscopes , and in the 1960s, a wide variety of science toys and kits.
LENS mission is focused on three main goals: [2] facilitating the scientific collaboration between European researchers in the field of linear and non-linear spectroscopy; providing the most advanced equipment available, assistance and advice to qualified researchers; conceive, plan and carry out research projects in collaboration with other universities and institutions both nationally and ...
The lens focuses light in the same way as a conventional lens. Gradient-index (GRIN) optics is the branch of optics covering optical effects produced by a gradient of the refractive index of a material. Such gradual variation can be used to produce lenses with flat surfaces, or lenses that do not have the aberrations typical of traditional ...
Fifth grade (also 5th Grade or Grade 5) is the fifth or sixth year of formal or compulsory education. In the United States, this is mostly the last grade of primary school, but for some states, it could be the first year of middle school. Primary school generally goes from Kindergarten and ends in fifth or sixth grade. Students in fifth grade ...
The lens is located towards the front part of the vertebrate eye, called the anterior segment, which includes the cornea and iris positioned in front of the lens. The lens is held in place by the suspensory ligaments (Zonule of Zinn), [1] attaching the lens at its equator to the rest of the eye [2] [3] through the ciliary body.
