Knowledge Zone#KnowledgeBit: #Geospace is the region of near-Earth space, extending from the upper atmosphere to the boundary where Earth's magnetic field meets solar wind, roughly 1.5 million km away.
#KnowledgeBit: In probability theory, the birthday problem asks for the probability that, in a set of n randomly chosen people, at least two will share a birthday.
The #Birthday #Paradox refers to the counterintuitive fact that only 23 people are needed for that probability to exceed 50%.
#KnowledgeBit: A #Leap #Second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between:
- Precise time (International Atomic Time (TAI), as measured by atomic clocks), and
- Imprecise observed solar time (UT1), which varies due to irregularities and long-term slowdown in the Earth's rotation.
#KnowledgeBit: #Cislunar #Space is the 3D volume of space between the Earth and the Moon, extending beyond the Moon's orbit and including the five Earth-Moon Lagrange points.
#KnowledgeBit: #Mount #Roraima is the highest of the Pakaraima chain of tepuis (table-top mountain) or plateaux in South America.
It is composed of Proterozoic age sandstone formed about 1.7 to 2 billion years ago, and hence amongst the #Oldest rocks on Earth.
#KnowledgeBit: #Muscle #Memory is the process by which the brain encodes specific motor tasks into the subconscious through repetition, allowing them to be performed accurately without active thought.

#KnowledgeBit: The #Library of #Alexandria in #Egypt was the most significant center of scholarship in the ancient world.
Founded in the 3rd century BCE under the Ptolemaic dynasty, it aimed to house "all the knowledge of the world".
#KnowledgeBit: #Quantum #Materials are materials whose properties cannot be fully described by classical physics alone, but require the principles of quantum mechanics to understand their behavior.

#KnowledgeBit: #Technosignatures are measurable scientific evidence of past or present technology created by extraterrestrial intelligence, acting as potential indicators of advanced alien civilizations.
#KnowledgeBit: #ShapeMemory is the ability of a material to be deformed and then return to its original shape when exposed to a stimulus. This ability is called the shape memory effect (SME).
A shape-memory alloy is an alloy that can be deformed when cold but returns to its original shape when heated. It is also known as memory metal, memory alloy, smart metal, smart alloy, and muscle wire.
