Quadrantanopia is a partial loss of vision in one quadrant of the visual field, meaning one-fourth of the visual field is lost. It can be due to various reasons such as brain injury, stroke, or certain neurological disorders.
The Quadrantids are a meteor shower that occurs every year around January 3-4 and is known for producing some of the brightest and fastest meteors in the sky. They are one of the most active and reliable meteor showers of the year, with a peak rate of up to 40 meteors per hour.<br><br>The Quadrantids are named after the now-obsolete astronomical quadrant, a type of astronomical instrument used to measure the position and angle of celestial objects in the sky. The shower is associated with the trail of debris left behind by an asteroid or comet, which is thought to be the remains of a short-period comet.<br><br>The Quadrantids are known for their speed, with meteoroids entering the Earth's atmosphere at a velocity of up to 42 km/s (26 miles/s), which is faster than many other meteor showers. This fast speed produces meteors that appear as bright, streaking stars, and often produce a persistent glow or smoke trail.<br><br>The Quadrantids are a relatively brief but intense meteor shower, with the peak typically lasting only a few hours, usually around 2-3 hours. However, the shower's radiant appears in the northern sky, making it visible from many parts of the Northern Hemisphere.
Quadrantopsia (also called quadrantopia or quadrant vision) refers to the suppression or loss of peripheral vision, specifically the portion of the field of vision located in one of the four quadrants of the visual field. This can result from various causes, including eye injuries, stroke, multiple sclerosis, brain tumors, or other neurological disorders that damage the optic nerve or brain regions responsible for processing visual information.
A person with quadriplegia, also known as quadraplegia, is a medical condition where a person has lost the use of all four limbs, resulting in a significant loss of motor function and independence. Quadriplegia is often the result of a severe spinal cord injury, usually at the cervical (neck) level. This condition can make everyday activities, such as dressing, eating, and communicating, extremely challenging.

Quadratic refers to a relationship between two quantities that is described in terms of a polynomial equation of degree two, i.e. each term has an exponent of 2 or less.
