The so-called "holy grail" of mathematics may have just been found. Shinichi Mochizuki, a professor at the Research Institute for Mathematical Sciences at Kyoto University, released a 500-page proof of the abc conjecture in number theory which involves the relationship between prime numbers, which I will attempt to describe as succinctly as possible below. A lot of open theory on prime numbers is based on the abc conjecture. This is high-level mathematics, which is even inaccessible to many mathematicians. Part I Part II Part III Part IV Mochizuki is a math genius who received his Ph.D from Princeton University at the age of 22 and hasn't slowed down since. So what exactly is the abc conjecture? The clearest explanation I could find of the abc conjecture is this single paragraph from the ABC@home project from the Mathematical Institute of Leiden University: *The rad(abc) is the "product of the unique prime factors of a,b, and c" What's the Significance?

The role of the forensic anthropologist can be varied, including aiding in the collection and analysis of human remains, the identification of victims beyond recognition, the estimation of time since death, and the establishment of injuries and potentially cause of death. The victims examined by anthropologists are usually in the late stages of decomposition, are completely skeletonised, or have been rendered otherwise unrecognisable by fire damage or other injuries. The forensic anthropologist will sometimes be called in when suspected human remains are first discovered to aid in the excavation and initial analysis of the bones. Following the careful excavation, documentation and collection of the remains, they are cleaned up in preparation for the analysis. The skull is equally beneficial in the establishment of sex.
