The Van Allen radiation belts are giant swaths of magnetically trapped highly energetic charged particles that surround Earth.
These belts, discovered in 1958, are located in the inner region of Earth's magnetosphere and consist mainly of high-energy protons and electrons. They are held in place by Earth's magnetic field and play a crucial role in protecting our planet from harmful solar wind and cosmic radiation. However, they can also pose a hazard to satellites and astronauts traveling through them.
There are several formulas and conventions used to represent the three-dimensional structures of molecules on a two-dimensional surface. The most common and important ones include:
Solid lines: Represent bonds that lie in the plane of the paper or screen.
Solid wedges (or bold lines): Represent bonds that are coming out of the plane of the paper or screen, towards the viewer. Dashed wedges (or dashed lines): Represent bonds that are going behind the plane of the paper or screen, away from the viewer.
Existing designs could continue to coexist with a 2.0 W/kg SAR limit averaged over 10 grams of tissue until August 31st, 2013. The statement also accurately reflects that the SAR limit was averaged over 1 gram of human tissue.
Therefore, if we are being very broad and considering the underlying technology, one might argue that the ringing of a digital alarm clock is a morning ritual enabled by devices that function due to quantum mechanics.
It's important to clarify that the act of the alarm ringing isn't itself a quantum mechanical phenomenon on a macroscopic scale, but the technology behind it is rooted in quantum mechanics.
