@jon-nyc it's called an "electrician's" or "underwriter's" knot:

Used in lamps and things like that.

That looks wrong. The two cables are supposed to be part of a bigger cable, and that bigger cable is supposed to be fixed by the two screws.

I think such cords would be illegal over here.
Our power cables look like this.

It's not obvious in the picture, but I suspect the Blue and Red wires are joined.
Except where they are separated in order to tie the knot.
The 2 wires form a single strand that can be easily pulled apart. Outside of a fixture the covering between the 2 wires is joined.

Klaus, you wouldn't believe the wiring over here. It's unbelievable. I feel like I'm taking my life in my hands every time I wire a plug or install a fixture. The first time I opened up a plug in Canada I thought it was a practical joke.
I'm guessing it's a function of having half the voltage, but still.....

But half the voltage means twice the current, which makes proper cables and connectors even more important.
I’m always amazed when I visit the high tech country USA to then find all these utility roads with overland cables and wires that look like in a third world country.

It's funny how the priorities differ. When we lived in Canada, the heating systems and protection against the cold were amazing - we were far warmer than we'd ever be in an English house, where they seem to build in the mistaken belief that the UK is a tropical country. But the electric systems were shocking, if you'll forgive the pun.
We live in a fairly built up area - a relatively busy suburb of Boston, but we still don't have a sewerage system, the house has a septic tank. The town tried to get people to vote for a sewer, but got voted down because nobody wanted to pay, despite the fact that the water table is in real danger of being corrupted.

I remember my first visit to France in 1991. My friend’s apartment had a Minitel. That’s the last time I was impressed by European technology.

Baritone Leonard Warren died onstage at the Met in 1960 just as he finished singing Verdi's "Morir, Tremenda Cosi," which means "To Die, A Momentous Thing."

The Appalachian mountains are actually split between North America and Europe. How can that be? They are older than the Atlantic Ocean.
The mountains were formed before there were land animals, indeed even before fish had evolved. As a result most of the fossils seen on them are from early marine life.
Only non-witches get due process.

Very cool - every time I'd hike in the Shenandoah I'd often think about this.
