Definition: Describing light or other electromagnetic radiation that has a higher frequency or shorter wavelength than it originally had, often due to the source moving closer to the observer.

Example: The light from the approaching star appeared blueshifted, indicating it was moving towards us.

Definition: A man-made radioactive element with the atomic number 107, known for its very short lifespan and produced in laboratories.

Example: Bohrium is used in scientific research to study the properties of heavy elements.

Definition: The quality of being noisy, energetic, and cheerful, often in a lively or rowdy way.

Example: The boisterousness of the children playing in the park filled the air with laughter.

Definition: A device used to measure the amount of radiant energy by detecting changes in electrical resistance caused by absorbed radiation.

Example: The scientist used a bolometer to measure the infrared radiation emitted by the heated object.

Definition: Relating to the measurement of the total energy of electromagnetic radiation, especially in the context of astronomy and physics.

Example: The bolometric measurements provided crucial data for understanding the star's energy output.

Definition: In a way that relates to measuring the total energy of radiation, typically using a device called a bolometer.

Example: The researchers measured the star's brightness bolometrically to get a complete picture of its energy output.

Definition: A heavy attack or continuous firing of artillery or bombs, often directed at a specific target such as a city or military position.

Example: The city suffered extensive damage due to the relentless bombardment during the war.
