The Canada Science And Technology Museum underwent a large scale reconstruction several years ago, so I had never seen the building as it once was. It explores science, technology, and the way that Canadian society interacts with both. The permanent exhibits here are largely organized thematically, with room to wander between them. The central passage, called Artifact Alley, is framed by display cases featuring technology- some old, some new. Cameras, computers, phones, clocks? They're all here.
Even telegraph keys. Oddly, telegrams are still sent in this day and age.
Our way of listening to music has changed over the decades, something highlighted both in this area and elsewhere in the museum.
This is a linotype machine, used for printing, used primarily between 1900-1950.
They don't make them like this anymore.
Another printer up above- this case being a hand press, circa 1837.
Lights and telescopes featured here.
Here we have a Fresnel lens. This is commonly used in lighthouses, concentrating light shone through it and allowing it to be seen from much further away.
Here we have navigation instruments- sextants, octants, and compasses.
