What if we could look inside human brains? - Moran Cerf
Is light a particle or a wave? - Colm Kelleher
what i did:
1.This week I only watch each of them twice because I don't have enough time,too much homework...
2.I did some research on whether light is a particle or a wave, it turns out to be both.
3.I watched the videos without the words for the first time and then watch the words for the second time,to compare if my understanding was right or not.
