John Wellborn Root Jr. (July 14, 1887 – October 24, 1963) was a significant United States architect based in Chicago.He was the son of architect John Wellborn Root.As a young man, he graduated from Cornell University and studied architecture at Paris' École nationale supérieure des Beaux-Arts, where he became friends with John Augur Holabird, the son of another famous Chicago architect.
Topcolor is a model in theoretical physics, of dynamical electroweak symmetry breaking in which the top quark and anti-top quark form a composite Higgs boson by a new force arising from massive "top gluons". [1] [2] The solution to composite Higgs models was actually anticipated in 1981, and found to be the Infrared fixed point for the top ...
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
Casual use in an engineering class has been cited as evidence of the sexism faced by women in scientific fields. [15] Latanya Arvette Sweeney , associate professor of computer science at Carnegie Mellon , mentions yet another as one reason why she felt alienated and eventually dropped out of MIT in the 1980s to form her own software company.

The concept of Helmholtz resonance is fundamental in various fields, including acoustics, engineering, and physics. The resonator itself, termed a Helmholtz resonator, consists of two key components: a cavity and a neck. The size and shape of these components are crucial in determining the resonant frequency, which is the frequency at which the ...
The Mathematisch-Physikalischer Salon (German: [mateˈmaːtɪʃ fyziˈkaːlɪʃɐ zaˈloːn], Royal Cabinet of Mathematical and Physical Instruments) in Dresden, Germany, is a museum of historic clocks and scientific instruments. Its holdings include terrestrial and celestial globes, astronomical, optical and geodetic devices dating back to the ...
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
