My 9-year-old son is gifted. He met the gifted criteria multiple times -- SCAT, WPPSI, etc and scores are pretty high.

He loves Physics and truly understands very advanced concepts, he is fascinated by optics and how the light behaves. I am not saying that as I am an overzealous parent but I truly think he understands it sometimes at even high school level.

He is begging to learn more and I am not sure what to do. I tried some middle school courses on study.com for physics but the problem is he understands the concepts easily but when the equations come or the formulas come he stops and runs away. I think there is advanced mathematics/ algebra which he doesn't like to do.

I am not sure how to nurture his hunger for physics. Any advice will be much appreciated.
