Allan La Grenade-Finch remembers the moment an 8th grader, a “great kid” who often sat in the back of class and struggled with science, “lit up” during last year’s Hour of Code at Cardozo Education Campus in Washington, D.C. (more…)
Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now a team of physicists, including one from North Carolina State University, has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ. Their findings may shed light on how oxygen is produced.
Carbon and oxygen are formed when helium burns inside of red giant stars. Carbon-12 forms when three helium-4 nuclei combine in a very specific way (called the triple alpha process), and oxygen-16 is the combination of a carbon-12 and another helium-4 nucleus. (more…)
