Surname 1 Logarithms Name: Professor: Course: Institution: Date: Introduction Logarithms entail expressing numbers using notions like log or in. They are used in wide area of applications since many areas that require mathematical concept such as chemistry and physics require the concept of logarithms. Many people argue that logarithms are complicated but they are easy to understand how they work. Logarithms have many uses in real life situation but many people do not understand their application since they limit themselves to mathematical concept. Generally, the paper will discuss in details...

4 How does Cesium atom clock works and why it is used for time keeping purposes? Name Professor Course Institution Date Abstract Timekeeping is made possible due to the fact that the counting interval can be done repeatedly without high variation. Although mechanical means for example use of amechanical pendulum can be used in timekeeping, such methods are not as effective as theuse of atomic clock for time keeping. Although there are a number of elements that can be used in the atomic clock, Cesium is the most preferred element...

Also, it allows control of running simulations and interactive display when used with the parallel molecular dynamics code namd. NAMD Configuration files these are the files specifying virtually everything about the simulation to be done. It specifies the dynamic values and options that NAMD uses such as the initial temperature, number of timesteps to...

Running head: SUB-RETINAL AND ALPHA TECHNIQUES 1 SUB-RETINAL AND ALPHA TECHNIQUES 5 Sub-retinal and Alpha Techniques Student’s Name Instructor Affiliation Date of Submission Sub-retinal is a standard retinal implantation classified according to the electrode array. Sub-retinal results from the growth of sub retinal membrane, a fibrous tissue of thin sheets developing on the surface of macula affecting the central vision. The technique of sub retinal implantation becomes quite challenging due to the position of sub retinal space. Sub retina employees a simple surgical procedure of targeting restoration of vision by...

Running Head: X-RAYS 1 X-RAYS 6 X-rays Student’s Name Institution Affiliation Date of Submission I have a great enthusiasm in studying X-rays as one of the electromagnetic radiations, commonly used in electronic imaging. In the electromagnetic spectrum, X-rays lie in-between the ultraviolet rays and gamma rays. Due to the decrease in wavelengths, X-rays have higher energy than the ultraviolet rays and a lower energy than gamma rays. According to Robinson and Tweet (1992), X-rays exhibit particle-like properties. In this case, I can easily describe X-rays as the flow of photons...

Running head: MY WORLDVIEW 1 MY WORLDVIEW 4 My Worldview Name Institution Understanding your personal worldview is significant because it helps to understand your own philosophy. This is how we evaluate all aspects of life, the world around us and our place in it. Looking at the life of a man, it is difficult for him to believe in something that he cannot see, touch or feel. It is hard for him to understand and define terms like God, ethics, and knowledge, although they play a huge role in shaping...
