Of Music

 These older devices certainly show imagination.

This music box played metal disks.

While this played paper rolls, much the same principle as a player piano.

Radios and other music players have evolved over time.

There is a room here engineered for quiet. It is bathed in blue light, designed with sound dampening qualities. I was in here with other people, whose words were muffled. I should have stayed a bit to see how it sounded alone.

Here we have portable radios.

And the walkman.

Adapted

We shift into adaptive technology today, with a kayak designed for those with mobility issues in the lower legs.

A unique adaptation- a climbing rig. Brad Zdanivsky was a climber with partial quadriplegia. He used this to work his way up a mountain, using his upper arms with pulleys to pull himself up.

The sit-ski can be used for those with mobility issues to cross country ski.

And this handcycle enables for travel over rough ground.

A look at things to come.

I moved into an area focusing on sound, with older appliances capable of playing music.

Motion

 Another look at the 3D scanned mine today.

Here we have a Smart Car, reduced down to its components.

We shift into recreation, with items like a canoe and a very old car.

A relatively newer car, with a camping trailer.

And bicycles.

Snowmobiles have changed over time, becoming more streamlined.

Snowshoes have been used by indigenous peoples for thousands of years to cross over snow. They endure today, but mostly for recreational use.

Mining

It was today in 2013 that Ottawa Daily Photo got its start. Time does fly. 

Continuing on where we left off yesterday with this look at mining in the Science and Technology Museum.

Indigenous peoples were mining and trading in precious metals for thousands of years. After European contact, mining would eventually change.

Lights in mines can vary.

Mined metals can become highly prized gems. This jewellry set was a state gift to the wife of a former prime minister from the king of Saudi Arabia (seems like a bribe, doesn't it?). Now it is here.

New technology is meant to explore for mineral resources and help make the process run smoothly. This includes satellite technology and devices that scan and create 3D maps.

A simulator is found here. You can take the controls and drive through a mine that has been intensively scanned. The video screen is in black and white, and is vivid.

Energy

A reminder to members of City Daily Photo that the theme for October 1st is Soft. 

Here we have a toaster, broken down into component parts, consisting of numerous resources.

Various kinds of lights are seen here.

Power comes from various sources. Hydro power is represented here.

This presented the many kinds of plastics and other materials going into toys, in a chaotic arrangement.

Here we have a magnetized target fusion device.

Nuclear fission is another source of energy.

We move now into an area focusing on mining.

Contemporary and old- at top is a Canadian design, the Lunabot, winning a NASA competition for vehicle most effective at collecting mineral samples on the Moon. Below it is a very old mining car, dating to the 19th century.
