#KnowledgeBit: A #Twin #Prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (17, 19) or (41, 43).
Twin primes become increasingly rare as one examines larger ranges. However, it is unknown whether there are infinitely many twin primes (the so-called twin prime conjecture) or if there is a largest pair.

#KnowledgeBit: 2I/Borisov, originally designated C/2019 Q4 (Borisov), is the first observed rogue comet and the second observed interstellar interloper after ʻOumuamua.
Discovered by amateur astronomer Gennadiy Borisov on August 30, 2019, from his personal observatory in Crimea, its hyperbolic trajectory immediately indicated that it originated from outside our solar system.

#KnowledgeBit: #Nuclear #Transmutation is the fundamental process of converting one chemical element or one isotope into another by changing the number of protons or neutrons in the atom's nucleus.
This process is distinct from chemical reactions, which only involve the rearrangement of electrons and do not alter the nucleus itself.

#KnowledgeBit: #PillarsOfCreation, a #Photograph taken by the Hubble Space Telescope, is possibly the most famous example of 'elephant trunks' of interstellar gas and dust in the Eagle Nebula, in the Serpens constellation.
They are so named because the gas and dust are in the process of creating new stars, while also being eroded by the light from nearby stars that have recently formed.

#KnowledgeBit: The Karl #Weierstrass #Curve (or Weierstrass function) is a famous math curve that is continuous everywhere but has no derivative anywhere.
This means you can draw it without lifting your pencil, but it is too jagged and pointy to ever have a smooth slope or straight tangent line

#KnowledgeBit: #Solastalgia is the emotional or existential distress caused by the negatively perceived environmental change of one's home and surrounding environment.
Unlike nostalgia, which is a yearning for a home one has left, solastalgia is the "homesickness" experienced while still at home because the environment has been altered beyond recognition.

#KnowledgeBit: The Great Pacific Garbage Patch is a collection of marine debris, primarily plastic, found in the central North Pacific Ocean. It is estimated to cover an area of approximately 1.6 million Sq Km.
It's not a solid island of trash, but rather a gyre (a swirling system of ocean currents) where plastic debris concentrates.

#KnowledgeBit: The "#Tree of Life" is a metaphor and research tool used to explore the evolution of life and describe the relationships between all organisms, both living and extinct, through common descent.
Rooted in the concept of common descent, its structure is a vast phylogenetic tree where the 'trunk' represents the single universal ancestor, and the 'branches' signify the evolutionary divergence and speciation that have occurred over billions of years.

#KnowledgeBit: #Magnetic #Refrigeration is an emerging, eco-friendly cooling technology that relies on the magnetocaloric effect rather than traditional harmful chemical gases and compressors.
By repeatedly magnetizing and demagnetizing solid-state materials (like gadolinium), the system achieves efficient cooling through atomic particle alignment and randomization.
