Generalized coordinate by Ciro Santilli 37 Updated 2025-07-16
The variables of the Lagrangian, e.g. the angles of a double pendulum. From that example it is clear that these variables don't need to be simple things like cartesian coordinates or polar coordinates (although these tend to be the overwhelming majority of simple case encountered): any way to describe the system is perfectly valid.
In quantum field theory, those variables are actually fields.

Defined in the 2019 redefinition of the SI base units via the Planck constant. This was possible due to the development of the Kibble balance.
Vector graphics by Ciro Santilli 37 Updated 2025-07-16
Smaller files, scalable image size, and editability. Why would you use anything else for programmatically generated images?!?!
Agilent Technologies by Ciro Santilli 37 Updated 2025-07-16
In a way, Agilent represents the most grassroots electronics parts of HP from before they became overly invested in laptops and fell.
They spun out the electronics part as Keysight in 2014, becoming life science only.

Ahh, Ciro Santilli was certain this was some slang neologism, but it is actually Greek! So funny. Introduced into English in the 19th century according to: www.merriam-webster.com/dictionary/kudo.
Nu (letter) by Ciro Santilli 37 Updated 2025-07-16
Why would physicists use a letter such that:
  • the upper case version looks exactly like an upper case N. At least that is the correct pronunciation/name/historical successor of .
  • the lower case version looks exactly like a lower case V
Why? Why?????????
