"Newton was sitting under an apple tree when an apple fell on his head and he discovered gravity. And we here are living in darkness and tragedy, and rockets are falling on us, therefore I thought of creating light, and did so."
English scientist Isaac Newton, who made immense advances in physics, mathematics and astronomy in the late 17th and early 18th century, stands out in the popular imagination due to the story of the apple.
More than half of Gaza's 2.3 million people are now crammed into Rafah, on the southern edge of the strip by the fence separating it from Egypt.
