These energy beams could be directed at the sail to launch it into space and provide a secondary power source during its journey. In one experiment at NASA's Jet Propulsion Laboratory (JPL), sails were driven to liftoff using microwave beams, while laser beams were used to push the sail ...
Place the reference probe and the probe you’re calibrating in the temperature source. Try to keep them close together, in a circle, with the reference probe in the center. Connect the leads to the readout that measures the probes. This may be the calibration readout or it may be the ...

Photo: Electronic medical thermometer from 2010. You put the metal probe in your mouth, or somewhere else on your body, and read the temperature off the LCD display.Electronic thermometers work in an entirely different way to mechanical ones that use lines of mercury or spinning pointers. They...
large enough to fit the laboratory thermometer. The fit should be snug, though, so no heat will escape through the hole. Insert the thermometer far enough through the lid so the sensitive end will reach near the bottom of the coffee cup and the temperature can be read from the opposite ...
pH meters come in various forms, catering to different needs and budgets, including compact pen-style meters, handheld meters with separate probes for pH and temperature, and more advanced benchtop models designed for laboratory use. When selecting a pH meter for homebrewing, several key features ...
Put a thermometer inside to measure the temperature. Then, arrange the light so that it shines directly on the box. After 20 minutes, record the temperature inside the box. Next, set a house plant between the lamp and the box so that its shadow rests on the "house." You can also ...
and stood it upright in the mercury bowl. Since he was careful not to let any air into the tube, the space that formed above the mercury column was a vacuum. Indeed, this was the first time anyone had ever produced a vacuum in a laboratory (and a vacuum made this way is called a ...
