Strange underwater icicles form in the Earth’s coldest regions and freeze living organisms in place.
In physics, nonreciprocity occurs when a system’s response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which essentially means that a system’s processes observed as they evolve over time will be different compared to those processes observed on rewind.
The bestselling author of Seven Brief Lessons on Physics introduces the mysteries of time, further explored in his new book, The Order of Time.
Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple idea we have of it. From Einstein to quantum theory and beyond, our understanding of time has been undergoing radical transformations. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.
The Order of Time will be available in hardback and in audiobook read by Benedict Cumberbatch on April 26th 2018

At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
