Measurement is a very important parameter in the field of physical sciences. Different methods of measurements have used to determine various aspects of the physical environment. Units precede every kind of measurement. They help in giving a description of the physical quantity in question hence enhancing comparison. The three major quantities in physics include length measured in meters, time measured in seconds and mass that is measured in kilograms. The Metric system of measurement has been adopted in most of the countries of the world while the British System of measurement, famous for use inches, miles, and pounds among others has a minimal use in the world despite its ubiquitous use the United States of America. Despite the technological progress experienced in the world today, several challenges are encountered in the measurement of the physical environment. Every measurement made has an associated error that should be recognized whenever a quantity is measured. This error has a numerical value that tries to correct the quality of the estimation done through measurement. Furthermore, it can be in form of a standard uncertainty, whereby the error has a standard figure or a coverage interval whose figure will have a given range of values. However, efforts have been made in trying to minimize these uncertainties. The International Organisation for Standardisation (ISO) has developed “The Guide to the expression of Uncertainty in Measurement” to help in enacting a common approach to the errors encountered in measurement. In astronomical sciences, it is difficult to use direct measurement calling for indirect measurement strategies. A unique method utilised by the astronomers is the parallax method. This method involves observation of the position of heavenly bodies at different times. They consider factors such as the precise location of the body, the time, the diameter of the earth’s orbit, the angle of viewing to elucidate the distance from the earth the heavenly body is located. Geometry is a key science in the calculations since the process involves analysing angles and distances to obtain an unknown distance (Finkelstein 2009). Such distances are unverifiable hence the exact distance especially for heavenly bodies to the sun cannot be determined in precision. Another major setback in measurement is lack of coherence in the communication of measurements. In quantum mechanics, disparities occur because of non-compliance with the recent regulations but instead trusting the predefined and pretested strategies. Space and time are aspects that have depicted some major measurement differences because of their reconstruction from observable quantities. This has created massive measurement challenges in quantum mechanics (Gambini and Pullin, 2012). According to the duo, there occur instances when the quantum state of the machine cannot be differentiated from the statistical components throughout the measurements made. This dimension of thought predicts the possibility of other errors in the measurement of a physical system. Technology has influenced the way measurements are done in a great way. The advancement in the computing methods has revolutionised the way measurement of physical elements is made. It has become apparent that most of the measuring instruments have been digitised or they have a

Effective and efficient use of physical resources in line with organizational policies and procedures Physical resources are needed in the aerospace sub-contractors trade setting to pledge the association that has specific places or buildings to labour economically.
It presents a critical reflection of all the modules I undertook in my first academic year during both the first and the second semesters. It reflects on the lessons learnt from each of the modules and the personal objectives, aspirations, and goals both achieved and unachieved.
Every human being has a different body and thus different physical attributes. The study demonstrates the relationship between physical activities and sleep duration as exhaustion often demands for physical rest and sleep is considered as the best way of offering some rest to the body (Wolfson, et al, 2003).
An individual who specializes in this field is known as a physical therapist and performs medical examinations, diagnosis and the appropriate physical interventions to ensure that the musculoskeletal structures function effectively and efficiently. The field also includes consultation, research, education and administration.
An interesting curiosity has grown over the unknown, for instance the size of the earth, the depth of the seas, the size and capacity of the universe. Questions have been developed over his strange issues, and humans have forcefully involved their minds into trying to figure them out.
“The social sciences are a group of academic disciplines that study human aspects of the world. They diverge from the arts and humanities in that the social sciences tend to emphasize the use of the scientific method in the study of humanity, including quantitative and qualitative methods.
Today, physical activity features high on the list of priority health behaviors for government campaigns aiming to improve health in industrialized nations. Sport, on the other hand, has always been a conduit for a nation to express its identity. As exercise and sport are behaviors conducted in social contexts, social psychology has a significant role to play in understanding the motivation and behaviour of people involved in both recreational exercise for health and competitive sport.
In a typical workplace, there is a lot of interaction among the employees, the executive, and between the employees and the employer. This interaction has mixed results, including improved interpersonal relationships and often, conflict. When there is a difference in opinion and interests, workers may resort to inappropriate methods to settle scores.
