Science-related Homebrew tap.
Assuming you already have Homebrew installed, you can use this tap via the following terminal command:
brew tap gwinstanley/science
and then you can install its formulae as usual (brew install ...), and they should show up in formula searches (brew search ...).
Similarly, casks may be installed as usual (brew cask install ...). You are recommended to install casks on macOS with the --no-quarantine flag to ensure macOS Gatekeeper isn't obstructive when trying to run an application. (If you don't include this flag you will very likely see a message that macOS identifies the application as corrupted, and request that it be deleted.)
