TASI meaning in Governmental ?

The Theoretical Advanced Study Institute or TASI is a four-week summer school in high-energy physics or astrophysics held yearly at the University of Colorado at Boulder. The school is meant primarily for advanced graduate students and consists of a series of pedagogical lectures on selected topics given by active researchers in the field. TASI is the most common summer school attended by high-energy physics graduate students in the United States.

Writeups of the TASI lectures are traditionally collected into a published volume each year, creating a valuable resource for students hoping to learn about current research topics in an accessible way. The writeups are typically also posted by the lecturers on arXiv.org, providing freely-accessible web-based sources on various physics topics. Since 2007, TASI has also posted video recordings of the lectures online.
