Uniform motion

This setup was used to determine the change in position of the glider in time in the uniform motion. Below there is a graphical representation of the findings.

The graph was done in Excel. Slope of the regression line represents the actual speed of the glider.

Celsius vs. Fahrenheit (°C vs. °F)

The thermometer shown in the picture gives readings in both degree Celsius and Fahrenheit. The same temperature can be measured using either one of them. Countries that use the metric system, including Canada, use the Celsius scale; in the US we use degree Fahrenheit. This thermometer was bought at the border.

Celsius scale:

water freezes at 0° and boils at 100°. 

Fahrenheit scale:

water freezes at 32° and boils at 212°.

- 40 °F = - 40 °C

You can convert degree Fahrenheit to Celsius and Celsius to Fahrenheit. Here are the formulas:

°C = (°F - 32) * 5/9

°F = °C * 9/5 + 32

About electricity

ELECTRICITY, n. The power that causes all natural phenomena not known to be caused by something else. It is the same thing as lightning, and its famous attempt to strike Dr. Franklin is one of the most picturesque incidents in that great and good man's career. [...] Electricity seems destined to play a most important part in the arts and industries. The question of its economical application to some purposes is still unsettled, but experiment has already proved that it will propel a street car better than a gas jet and give more light than a horse.

This is funny definition of gravitation

GRAVITATION, n. The tendency of all bodies to approach one another with a strength proportion to the quantity of matter they contain - the quantity of matter they contain being ascertained by the strength of their tendency to approach one another. This is a lovely and edifying illustration of how science, having made A the proof of B, makes B the proof of A.
