Measurement in Science Direct There are 3 direct problems with astronomy. Examples are, charting and mapping difficulties, military range finding targets, and gauging distances to any solar object. A researcher cannot measure something directly if it is not in the grasp of his devices. In which, a scientist will have to use geometry to find his answers. However, there are boundaries to calculating accuracy. (Pogge, 2006)
Indirect
Indirectly scientists can measure stars with Parallax measurements. Parallax says that stars move around other motionless stars because the earth rotates around the sun. Parallax acts as if the person spotting the stars move and then the place where the object is changes. The starting point that expert will use is the earth. Each measurement is founded on 6 month intervals. (Astronomy, 2009)
Historical tools
Telescope
One of the most historical tools was the telescope. Which Galileo Galilei perfected the telescope that was originally created by Hans Lippershey. Most of the earliest versions of the telescope used a curved lens made of polished glass at the end of a tube to magnify objects to a factor of 3x. Galileo was the first person to actually see different masses far within space. It gave way for scientists to see stars, planets, and space. Also, the telescope helped scientists to venture out and study planet surfaces. (Wethington, 2009)
Generator
Another tool is the generator. Michael Faraday was acknowledged for findings of electromagnetic induction and the laws of electrolysis. One of the 1st electric transformers was due to the induction ring. Turning disc between the poles of a horseshoe magnet Faraday found an uninterrupted direct current. Which today we use generators during an emergency situation or whenever a person may need electricity when there is none available. (Bellis, 2013)
