Dept. of Special Education Designs A8M Digital Learning Tool for Students in Need

October 15th is the White Cane Safety Day, the Day of the Blind. In order to reduce the learning difficulties of blind students in mathematics, Associate Professor Chien-Huey Sophie Chang of the Department of Special Education of NTNU led a team to develop the "A8M Digital Learning Tool" which is convenient for visually impaired students to read and write mathematics. It is easy to use and enables teachers to communicate well with visually impaired students. Users can listen and read repeatedly with a Braille display, which makes it easier to grasp the structure of complex mathematical formulas.

He encourages students to learn and understand knowledge in different disciplines to create unique value.

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.
