Definition: Relating to the geometry that is based on the principles established by the ancient mathematician Euclid, which includes concepts like points, lines, and planes in flat space.

Example: In Euclidean geometry, the angles of a triangle always add up to 180 degrees.

Definition: Relating to the geometry developed by the ancient Greek mathematician Euclid, which is based on the study of flat surfaces and shapes.

Example: The principles of Euclidian geometry are taught in many high school math classes.

Definition: A type of stony meteorite that is mainly made up of two minerals called pigeonite and plagioclase.

Example: Scientists discovered a eucrite that provided valuable information about the early solar system.

Definition: A glass tube that is closed at one end and marked with measurements, used to measure the volume of gases during chemical reactions.

Example: The scientist used a eudiometer to measure the gas produced in the reaction.

Definition: Relating to a device used for measuring the composition of gases, especially in chemical analysis.

Example: The eudiometric method is essential for determining the purity of the gas samples.

Definition: Connected to the study or practice of improving the genetic quality of a population, often through selective breeding.

Example: The eugenic policies of the early 20th century aimed to enhance the genetic traits of future generations.

Definition: In a way that relates to the study of improving the genetic quality of a population, often through selective breeding.

Example: The scientists discussed the implications of their research eugenically, considering the ethical aspects of genetic selection.

Definition: A person who supports or studies the idea of improving the human population through controlled breeding and genetics.

Example: The eugenicist argued for policies that would promote genetic health in future generations.

Definition: The study of improving the human race by controlling which people are allowed to reproduce, often based on certain traits or characteristics.

Example: Eugenics was a controversial movement that aimed to improve the genetic quality of the human population.

Definition: A clear, colorless liquid that has a pleasant smell, often used in dental care and perfumes, and is derived from clove oil.

Example: The dentist used eugenol to help relieve my tooth pain during the procedure.
