Gardening boils down to doing and seeing for yourself. - Mike Garofalo, Pulling Onions Each band or level, being a particular manifestation of the electromagnetic spectrum, is what it is only by virtue of the other bands. The color blue is no less beautiful because it exits along side the...

there is no disputing the researched benefits of coffee on mental health for the majority of individuals. It is important to remember that caffeine is a diuretic and you should replace the amount of caffeinated beverage you consume with an equal amount of water to keep your ...
"Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science." - Edwin Hubble ...
But 10 years after its completion, it is still the only all-sky survey in the optical/near-IR region of the electromagnetic spectrum. In imaging at ≥10,000 square degree coverage, 2MASS is now being surpassed (by 4 magnitudes) by the Vista Hemisphere Survey (VHS) (McMahon et al., ...
In this context, one must consider different interactions of electromagnetic waves with the propagation medium, such as relief, atmospheric ducts, or rough surfaces. Due to the mesh-size limitation, rigorous methods are not suitable. Indeed, the discretization steps must be of the order 𝜆/10λ...
When the electromagnetic coil is energized, the electromagnetic force generated by the electromagnetic coil in the pilot valve moves to the right to overcome the tension of the spring, and the high-pressure refrigerant gas enters the left piston chamber through the pilot valve. At the other end,...
