the parahippocampal gyrus (or hippocampal gyrus) is a grey mattercortical region, a gyrus of the brain that surrounds the hippocampus and is part of the limbic system. the region plays an important role in memory encoding and retrieval. 

the parahippocampal place area (PPA) is a sub-region of the parahippocampal cortex that lies medially in the inferior temporo-occipital cortex. PPA plays an important role in the encoding and recognition of environmental scenes (rather than faces).

this region of the brain becomes highly active when human subjects view topographical scene stimuli such as images of landscapes, cityscapes, or rooms (i.e. images of "places")

the region was first described by Russell Epstein and Nancy Kanwisher in 1998 at MIT,.

in electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. a varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil.

transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. since the invention of the first constant-potential transformer in 1885, transformers have become essential for the transmission, distribution, and utilization of alternating current electric power.[

a transistor is a semiconductor device used to amplify or switchelectrical signals and power. It is one of the basic building blocks of modern electronics. it is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit

because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. because transistors are the key active components in practically all modern electronics, they are considered one of the 20th century's greatest inventions.

the first transistor was invented in 1947 at Bell Labs by John Bardeen, Walter Brattain, and William Shockley. this invention marked a significant milestone in electronics and laid the foundation for modern technology.

the American goldfinch (Spinus tristis) is a small North American bird in the finch family. the goldfinch is a granivore and adapted for the consumption of seedheads.

it is a social bird and will gather in large flocks while feeding and migrating.

is a small finch, 11–14 cm (4.3–5.5 in) long, with a wingspan of 19–22 cm (7.5–8.7 in). It weighs between 11–20 g (0.39–0.71 oz). among standard measurements, the wing chord is 6.5 to 7.8 cm (2.6 to 3.1 in), the tail is 4.2 to 5.1 cm.

the American goldfinch prefers open country where weeds thrive, such as fields, meadows, flood plains, as well as roadsides, orchards, and gardens. It may also be found in open deciduous and riparian woodlands and areas of secondary growth.

Random-access memory (RAM; /ræm/) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.

in modern technology, random-access memory takes the form of integrated circuit (IC) chips with MOS (metal–oxide–semiconductor) memory cells. RAM is normally associated with volatile types of memory where stored information is lost if power is removed. the two main types of volatile random-access semiconductor memory are static random-access memory (SRAM) and dynamic random-access memory (DRAM).

the use of semiconductor RAM dates back to 1965 when IBM introduced the monolithic (single-chip) 16-bit SP95 SRAM chip for their System/360 Model 95 computer, and Toshiba used bipolar DRAM memory cells for its 180-bit Toscal BC-1411 electronic calculator, both based on bipolar transistors.

a printed circuit board (PCB), also known as a printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate.[1] PCBs are used to connect or "wire" components to one another in an electronic circuit.

the greater blue-ringed octopus (Hapalochlaena lunulata) is one of four species of extremely venomous blue-ringed octopuses belonging to the family Octopodidae. this particular species of blue-ringed octopus is known as one of the most toxic marine animals in the world.

the greater blue-ringed octopus is capable of inflicting a deadly bite to its predators that can potentially be fatal to humans. octopuses from genus Hapalochlaena have two kinds of venom glands that impregnate their saliva.

one is used to immobilize the hunted crustaceans before eating them. the second, tetrodotoxin, is used for defense and is found in several other sea creatures such as pufferfish.

this toxin is a powerful neurotoxin and a strong paralytic. the bite is painless to humans but effects appear any time between 15 and 30 minutes

A galaxy is a collection of stars, systems, clusters and stellar associations, gas and dust (which form the interstellar medium), bound together by the force of gravity.  The name derives from the ancient Greek γαλαξίας, galaxìas ("milky", "milky"), in reference to the Milky Way, the galaxy to which the solar system belongs and the first observed.

Galaxies are the most numerous objects in the observable universe. A 2021 study estimates their number at a few hundred billion (1011), in contrast to a higher number calculated previously.  They are vast objects of extremely variable sizes; They range from the smallest dwarf galaxies, containing a few hundred million stars, to giant galaxies containing a number of stars on the order of one hundred trillion, orbiting a common center of mass.

Una galassia è un insieme di stelle, sistemi, ammassi e associazioni stellari, gas e polveri (che formano il mezzo interstellare), legati dalla forza di gravità.[] Il nome deriva dal greco antico γαλαξίας, galaxìas ("di latte", "latteo"), in riferimento alla Via Lattea, la galassia a cui appartiene il sistema solare e la prima osservata.

Le galassie sono gli oggetti più numerosi nell'universo osservabile. Uno studio del 2021 stima il loro numero in alcune centinaia di miliardi (1011), in contrasto con un numero più alto calcolato precedentemente. Sono oggetti vastissimi di dimensioni estremamente variabili; variano dalle più piccole galassie nane, contenenti poche centinaia di milioni di stelle, alle galassie giganti che contengono un numero di stelle nell'ordine di centomila miliardi, orbitanti attorno a un comune centro di massa.

A Fluidic Space Telescope

A telescope’s resolution is set by the size of its reflective surface. Our largest space telescope, JWST, has a 6.5-meter reflector, the largest we could manage given manufacturing constraints and the need to launch it in a rocket. To reach even larger sizes, researchers are considering a new type of reflector: one made of liquid. (Image credit: NASA; research credit: I. Gabay et al.)
