Hi Lawrence,
I will be doing "Flipped classroom" for my Pure Physics class next year, so I am converting the current textbook into a digital one by having students to paste QR codes that link to my teaching videos on their textbooks.
I have looked thru some of your applets and found them very effective in demonstrating certain concepts and theory, particularly the one on Brownian Motion. Hence, I would like to seek your permission to incorporate your applets in the digital textbook mentioned above.
Thanks in advance!
Regards,
Ming Yeo
