Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, resulting in fringing effects, which is termed diffraction.

The Nobel Prize in Physics 2019 was awarded to John Peebles of Princeton University, who enhanced our understanding of the structure and history of the universe. The other half went to Michel Mayor of University of Geneva, and Didier Queloz of Cambridge University for their discovery of exoplanet, a planet orbiting a solar star.

India versus New Zealand in overcast Manchester. Research has found that cloud cover and moist air facilitate swing bowling. (Reuters) It could be argued that the weather played a key role in the denial of a place to India in the World Cup final. The air was moist and there were clouds and rain in Manchester. Moisture content reduces cohesion and makes the pitch weak. A pitch with just 30-35 per cent clay, for example, becomes less cohesive when it rains, which favours swing and seam bowlers.
