| Hem Jung <hemjA@netco.net>: Mar 30 10:43AM -0400 Just had to power something pretty far away from the outlet and had to use a standard extension cord. Since this goes across the floor, I'm wondering if there's anything I can do to make this anti-trip? My foot has caught it a couple of times, so not very good if I keep it the way it is. I see flat extension cords online, but price is too high. Maybe I could make one? Thanks in advance. |

Rubber pieces that are a few inches wide that the cord goes under ? https://www.homedepot.com/p/Legrand-Wiremold-Corduct-5-ft-1-Channel- Over-Floor-Cord-Protector-Black-CDBK-5/205485211 There are many variations of this. |

Then Penzias and Wilson started looking for any possible terrestrial noise sources. Bird droppings are a lossy dielectric among their other less pleasant properties, so P&W cleaned their horn antenna carefully, calibrated the receiver, and so on, but the noise was still there. There's still science today that's done that carefully, but I fear it has gotten a lot less common. (Certainly the quality of papers I get sent to review has tanked in the last 25 years or so--and yes, it's the same journals.) Cheers Phil Hobbs |
