Happiness lowers your risk for cardiovascular disease, lowers your blood pressure, enables better sleep, improves your diet, allows you to maintain a normal body weight through regular exercise and reduces stress.

Have a lovely day. 🙏🏻❤️

Being in the sun can make people feel better and have more energy. Sunlight increases the levels of serotonin in the brain, which is associated with improved mood.

Metamaterial cloaking, based on transformation optics, describes the process of shielding something from view by controlling electromagnetic radiation. Objects in the defined location are still present, but incident waves are guided around them without being affected by the object itself.

A resonance chamber uses resonance to enhance the transfer of energy from a sound source (e.g. a vibrating string) to the air. The chamber has interior surfaces which reflect an acoustic wave. When a wave enters the chamber, it bounces back and forth within the chamber with low loss (See standing wave). As more wave energy enters the chamber, it combines with and reinforces the standing wave, increasing its intensity.

Since the resonance chamber is an enclosed space that has an opening where the sound wave enters and exits after bouncing off of the internal walls producing resonance, commonly acoustic resonance as in many musical instruments (see Sound board (music)), the material of the chamber, particularly that of the actual internal walls, its shape and the position of the opening, as well as the finish (porosity) of the internal walls are contributing factors for the final resulting sound produced.

The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere.

Electromagnetic resonance is a phenomenon produced by simultaneously applying steady magnetic field and electromagnetic radiation (usually radio waves) to a sample of electrons and then adjusting both the strength of the magnetic field and the frequency of the radiation to produce absorption of the radiation.

Climate models include more atmospheric, oceanic and land processes than weather models do—such as ocean circulation and melting glaciers. These models are typically generated from mathematical equations that use thousands of data points to simulate the transfer of energy and water that takes place in climate systems.
