Not sure what is going to be built here in Bin Mahmoud, but from the depth of the excavation, it's probably going to be one tall building. Not tall as in Burj, but bigger than anything in the neighbourhood. I'm always amazed that they dig these deep holes in the middle of the city and protect the public with the flimsiest of corrugated iron fences, the type the wind blows down regularly, a mere two feet from the sheer drop. And the gaps in the fences are easily wide enough for all but the most obese to squeeze through. For the kids, it's a straight invitation.
The suspended walkway (below) doesn't look too safe either, but that's for the workmen so no-one's going to worry.
This song by Harry Gordon is about 100 years old and is in the Scottish music hall tradition. It's short because it was the lead into a stand-up comedy routine in character. The character in this case being a fireman on the footplate of a steam engine.
The triode was invented in 1906 by Lee De Forest and by around 1920 was refined enough to be commercially viable for widespread distribution. It was the World's first 'Active Device'. It could amplify and oscillate. It (and its derivatives) made possible all of the technologies of modernity – public address, radio, audio/video recording, television, radar, radio telescopy, electron microscopy, computing, the Internet, artificial intelligence. Without active devices, modernity would vanish in a flash. Those who really want to turn the clock back need only abandon science, technology and education. Nature will do the rest.
