Definition: A type of mathematical object used in physics and mathematics, particularly in the study of spaces with complex numbers and in theories like relativity.

Example: In quantum mechanics, spinors are essential for describing the behavior of particles with spin.

Definition: The quality or condition of having spines or thorns.

Example: The spinosity of the plant made it difficult to handle without gloves.

Definition: Describing something that has sharp points or projections, like spines or thorns.

Example: The spinous plant was difficult to touch without getting pricked.

Definition: A situation where a vehicle loses traction and rotates, often leading to it leaving the road.

Example: The driver lost control during the rain and experienced a spinout on the highway.

Definition: A tool used to see tiny flashes of light caused by particles of radiation hitting a special screen.

Example: The scientist used a spinthariscope to observe the alpha particles emitted from the radioactive sample.

Definition: A tiny spine or thorn-like structure, often found on plants or animals.

Example: The cactus was covered in small spinules that made it difficult to touch.

Definition: A small opening or hole that allows air to enter or exit, often found in animals like fish and insects.

Example: The shark uses its spiracle to breathe while resting on the ocean floor.

Definition: Relating to small openings or holes, especially those that allow air or water to enter or exit an organism.

Example: The spiracular openings on the insect's body help it breathe.

Definition: Having a shape that curves around a central point, getting closer or further away as it goes around.

Example: The staircase had a beautiful spiral design that made it look elegant.

Definition: To move in a circular and upward or downward path, often resembling a spiral shape.

Example: The smoke spiraled up into the sky.

Definition: A shape that curves around a central point, getting closer or farther away as it goes around, like a coil or a helix.

Example: The artist painted a beautiful spiral of colors in the sky.

Definition: To make something move in a circular and upward or downward direction, like a spiral shape.

Example: The artist decided to spiral the ribbon around the pole for decoration.

Definition: In a way that follows a spiral shape or pattern.

Example: The staircase wound spirally up to the top of the tower.
