- Scales in space and time: Introduction - OpenLearn
Across multiple scientific disciplines, from biology and chemistry to physics and geology, time scales are explored that include ages, durations and rates, and size scales including distances in three dimensions, which underpin areas and volumes.
This video provides a brief history of the Universe and gives details of its age and size today. The questions that follow will help you discover the time and space scales that correspond to the biggest and oldest objects in the size–time explorer.
Dynamical time represents the independent variable of the equations of motion of celestial bodies, spacecraft, and light rays in the solar system, measured in SI seconds relative to an established epoch and inertial coordinate reference frame.
15 kwi 2009 · In this video, Dr Dave Campbell talks about 4 different time and space scales that are commonly used by meteorologists to describe weather phenomena – global scale, synoptic scale, mesoscale and microscale.
1 sty 2023 · This chapter explores multiple aspects of scale as size when a temporal dimension is involved. It presents the process of time discretization and the implications of the sampling rate and illustrates them with examples. Scale as size in time is shown at work in relation to natural hazards and natural resources.
13 sie 2021 · Accretion disks around supermassive black holes in active galactic nuclei produce continuum radiation at ultraviolet and optical wavelengths. Physical processes in the accretion flow lead to stochastic variability of this emission on a wide range of time scales.
