www.FreeScienceLectures.com On one of the Moon missions, NASA astronauts decided to prove Galileo Galilei right. He reasoned that if there was no atmosphere, no dragging force then two objects of different mass falling from the same height would hit the ground at the same time. The astronomer drops a hammer and a feather on the surface of the Moon. — It’s Never too Late to Study www.FreeScienceLectures.com — Notice This video is copyright by its respectful owners.

A 3D presentation of the Galileo satellite navigation system, a joint development by the European Union and European Space Agency. This constellation of satellites will allow users to pinpoint their location anywhere on Earth — their launches commencing on 20 October 2011.

The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture.
Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of each tag is slightly different from the others. Since the bubbles are all hand-blown glass, they aren’t exactly the same size and shape.
The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. So, after the weighted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water.
As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, thereby changing its density. So, at any given density, some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature.

Galileo was unbeaten at this point of his career. He fared poorly in the Breeders Cup Classic in his only start on dirt, but terrific performances in Europe on grass, winning the Irish Derby and many other major races en route to being named champion 3-year-old in Europe.
Cylindrical thermometer and barometer set; inspired by Galileo?s instruments
Interprets temp and weather based on principles of buoyancy and air pressure
Colorful, liquid filled spheres descend and ascend with atmospheric changes
Barometer features the world globe etched in the glass
Mounted on a wood base; approximately 8 inches long and 8 inches high
