 [[Randall]] is bemoaning the fact that none of the efforts of people working in the IT sector, who may be spending even more time troubleshooting issues related to Wi-Fi connectivity on their site, have been recognised in the way that Penzias and Wilson have been.

Perytons looked similar to {{w\|Fast Radio Burst\|fast radio bursts}}, which are very energetic astronomical signals, the origin of which is still not understood. Perytons, on the other hand, were found to be the result of opening the door of a microwave oven in the radio observatory, which let out a short burst of microwave radiation as the magnetron in the oven turned off.
