A Chinese migrant worker with no college degree has found a solution to a complex math problem -- in what appears to be a real life version of the Oscar-winning movie "Good Will Hunting."
Yu Jianchun, who works for a parcel delivery company, said he'd always had a passion for numbers and has created an alternative method to verify Carmichael numbers.
His solution amazed academics, who said his proof was much more efficient than the traditional one.
