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) Survey of Safety

Hazard
There are all sorts of circumstances that can be called a hazard in physical science. It may not be anything like a biological or chemical threat. For example, if a person is collecting evidence for a particular study that person can accidentally touch their hand to their face without realizing that there was actually something on their hand, in which case causing a danger for that person. This can be in an open or closed environment. Mitigation

Of course it is always important to mitigate hazards by being aware of a person’s immediate surroundings. If a person is aware they are more inclined to use necessary precautions for their safety. As in the previous section if the person was wearing protective gloves and a face mask they would not risk getting an infection. Attentiveness is always key to preplanning. It is always preeminent to monitor safety precautions to avoid accidents form happening. Advancement in Physical Science

Pire
National Science Foundation (NSF) PIRE program allows global partnerships in exploration and learning to improve scientific explanations to overwhelming international encounters. Several of these plans involve experts in exploration to develop uncontaminated, harmless, dependable, inexpensive energy options, as the requirement for clarifications encounters people through the world. NSF's PIRE platform, founded in 2005, funds groundbreaking, universal examination and teaching. The depth and diversity of the projects aim to tackle global energy challenges the world over; in particular, they address timely topics such as: Establishing a winning formula for clean water, environmental sustainability and commerce Advancing low energy options for making water from wastewater Developing and assessing the impact of biofuels

Refining materials and applications for safe, reliable and sound nuclear energy Designing and constructing community-scale renewable energy micro-grids Developing materials for renewable energy
