Complexity Theory’s 50-Year Journey to the Limits of Knowledge
Impediments remain to proving NP-completeness for the full version of MCSP. But none are the sort of barriers that suggest an entirely new toolkit is needed — it may just be a matter of finding the right way to combine known techniques. A proof would finally settle the status of one of the few problems… Continue reading Complexity Theory’s 50-Year Journey to the Limits of Knowledge

While red giants are bad news for planets, they’re good news for astrophysicists. Their hearts hold the keys to understanding… Continue reading Quaking Giants Might Solve the Mysteries of Stellar Magnetism
Truth Decay and National Security
