Why do Astronomy? Bleeding edge Scientific Research No mysteries or licenses – Discoveries straightforwardly distributed, Universe accessible to All Friendly and Helpful Community: Open (aggressive) access to front line Telescopes Collaborations to develop Research or Instruments/Telescopes Taiwan Funding Agencies – Academia Sinica, National Science Council, and Ministry of Education Improve Science and Technology Graduate Education (Astrophysics, Mathematics, Engineering, Computers, … ) Technology exchange to Industry Public Support Strong Public interest, invigorates Education among all Ages
