Over 100 Universities Worldwide Send Well Wishes to NTNU’s 100th Birthday

On the occasion of the centennial celebration of National Taiwan Normal University (NTNU), 104 of the current 394 renowned global partner universities congratulated NTNU through videos and letters. Their heartwarming wishes bring the existing connection even closer.

Remarks by University President at the NTNU Centennial Celebration

Welcome to the centennial celebration of National Taiwan Normal University (NTNU). On behalf of our school, I would like to thank all of you for attending today’s celebration. I would also like to express my deepest thanks to our alumni and sister universities from around the world for your well wishes. Your support and encouragement make today’s events even more meaningful.

Detecting the size of primordial black holes with superhorizon perturbations

At the onset of the cosmic journey, the inflationary mechanism produced superhorizon curvature perturbations which affected the future formation of the universe. This study analyzed the growth of superhorizon curvature perturbations in the inflationary universe. Using a simple ultraslow-roll model, we derived the coherence function between any two points in the curvature perturbation. It showed that the causality limits the growth of the curvature perturbation, thereby constraining the important inflationary slow-roll parameters, allowing the universe to produce a large enough primordial black hole. Our research will help estimate how curvature perturbations form primordial black holes in the universe.

Current Exhibit of Restored Sculptures Showcases NTNU’s Dedication to Protecting Cultural Heritage

From September 2 to October 6, National Taiwan Normal University is showing “Restoration of Classic Sculptures,” an exhibit of 31 restored plaster replicas of classic Western sculptures. These plaster casts were purchased by NTNU from France more than 30 years ago; they are the only original copies with official copyrights licensed by the Louvre Museum. After two and half years of intensive collaborations and painstaking effort by faculty and students of the Fine Arts Department, the result of their labor is displayed to the general public in the basement level of NTNU’s Fine Arts Building.
