Chinese Seniors' Day Poem by William He

The Double Ninth Festival, also known as Chongyang Festival, is held on the ninth day of the ninth lunar month. It is also known as the Senior Citizens' Festival. In 2023, the Double Ninth Festival takes place on 23rd, October,2023. In ancient times, people believed that the double ninth day was worth a celebration. Since folk people had the tradition of climbing a mountain on that day, the Chongyang Festival is also called the Height Ascending Festival. The Chongyang Festival also has other names, such as the Chrysanthemum Festival. As 'double ninth' is pronounced the same as the word meaning 'forever, ' ancestors are also worshipped on that day. "Attosecond": "Atto"is the scientific notation prefix that represents 10 -18, which is a decimal point followed by 17 zeroes and a 1. Attosecond physics is the science of atomic-scale electronic motions, often triggered by light. The force that visible/infrared light waves exert on charged particles varies within hundreds of attoseconds. Electrons can respond to these hyperfast variations by changing their state (position, velocity) on the same time scale.
