How big is a grain of wheat? What is the metric unit for length? What is the tallest building in the US? How many Angstroms are in a meter? What does a barograph measure? How big is a micrometer? What is the maximum speed of the goldfinch?
These wavelengths are denoted in tiny distance units like microns (μ) or micrometers (μm), nanometers (nm), and angstroms (Å). Amicronequates to one-millionth of a meter (10-6meter); ananometeris equivalent to one-billionth of a meter (10-9meter) or one-thousandth of a micron,...
We talk a lot about process nodes at ExtremeTech, but we don’t often refer back to what a process node technicallyis.With Intel’s 10nm node now in production and TSMC + Samsung talking about future 5nm nodes, it’s a good time to revisit the topic, particularly the question of how ...
companies may begin referring to angstroms instead of nanometers, or we may simply start using decimal points. When I started work in this industry it was much more common to see journalists refer to process nodes in microns instead of nanometers -- 0.18-micron or 0.13-micron, for example,...
