Four elements have been added to the periodic table this year, completing the seventh row. However, these new elements are not naturally occurring. Scientists had to create them and overcome a number of challenges to do so.
An interactive Periodic Table? Yep! This video Ted-Ed Lesson is about every element on the periodic table. Thanks to Jelena of the STAO Curriculum Committee for this cool resource!
Jocelyn Bell Burnell is a Visiting Professor in Oxford (UK). She inadvertently discovered pulsars as a graduate student in radio astronomy in Cambridge, opening up a new branch of astrophysics — work recognised by the award of a Nobel Prize to her supervisor. Subsequently she has worked in many roles in many branches of astronomy, working part-time while raising a family. Increasing the number of women in science is important to her. In her spare time she gardens, listens to choral music, collects poetry with an astronomical theme, and is active in the Quakers (Religious Society of Friends).
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. 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)
