    "abstract": "It is demonstrated that thermal radiation of small occupation number is\nstrongly nonclassical. This includes most forms of naturally occurring\nradiation. Nonclassicality can be observed as a negative weak value of a\npositive observable. It is related to negative values of the Margenau-Hill\nquasi-probability distribution.",
