Physics of Wormholes :: physics science wormhole wormholes

Science fiction will often have fantastic stories about humans traversing stars at great speeds, faster than light. Vast interstellar civilizations are maintained by fleets of starships that fly from world to world in a matter of days or weeks. The truth, sadly, is far less fantastic. The universal speed limit is the speed of light, or approximately 2.998x108 m/sec. Nothing can move faster than that constant. Even at that extreme speed, it would take approximately 4 years for any spaceship to reach the closest of other stars. To make matters even worse, the energy required to accelerate an object increases exponentially as it gets closer and closer to the speed of light to the point where we cannot input enough energy to make the object actually go the speed of light. So how can we have these great galaxy spanning civilizations and expand our frontiers beyond the boundaries of our solar system? One possible solution is wormholes. This web project will attempt to inform on some of the basic theories of wormholes and how they could be used to traverse great distances and possibly even time itself. History Einstein first proposed wormholes in 1935. He co-wrote a paper with Nathan Rosen in which they showed that general relativity allowed for what they called â€Å"bridges.† They theorized that there could be places where space/time is folded that allowed transfer of matter from one point to another in the universe. After this initial burst of ideas in the thirties, wormhole theory was pretty much dropped by the world of physics in general. It wasn’t until the 1980’s when Carl Sagan wished to write his book Contact was wormhole theory revisited. Sagan wanted to have his protagonist leave Earth and arrive at a distant star system in a relatively short amount of time without being completely scientifically invalid. He turned to his fellow physicist Kip Thorne to develop an at least somewhat scientifically appropriate method of faster-than-light space travel. Thorne came up with much of the modern framework for wormhole theory that is in existence today for the book, which is now a major motion picture starring Jodi Foster. Definition A wormhole is a tunnel in space that matter can traverse through. It works in four dimensions with time being the fourth. It connects two points in the universe. A useful analogy for how a wormhole works is a two-dimensional piece of paper with a pair of dots on it.

Employee led innovation

Nevertheless, thanks for our work on mistakes we started to see obvious the inns today; we can ;t be successful when only one leader is thinking but we can look at the robber from different perspectives and find an appropriate solution when we are discussing it collaboratively. Therefore, the contribution of everyone is essential. Personally, I think that if employees would get enough right to tell their positions and to present new ideas, big corporations could achieve better goals in the end.In my country- Astrakhan and specifically in the regions of post-Soviet countries as Russia, Ukraine or Beleaguers employees are not treated as intellectual people and because of that fact, we have a big coordination among working and ruling class. That problem among employee and employer led to the ineffective work of whole company s workers. Good example of using the idea of employee led innovation is the system of Google workers. They are provided with freedom of action and do not restricted in their workplace.The main aim of Google Corporation is to provide comfortable conditions for their workers, so they II be able to use their time properly and the work will be effective. The good side of providing such workplace for employees is that they have a freedom and by appropriate time-management, they are able to work effectively on their big projects, and also they are open to new ideas, which can be presented to administration, thanks for what Google looks at the problems from different perspectives fixing every mistake in their search tool, finding the right way to increase audience etc.Furthermore, employees work directly with product and method of its production. It can be different product: informational, engineer or just simple production of food. Administration and leaders look only at result, which was achieved by the company, but they are not well informed about how the company is working inside and what problems does it have. Important thing to mention here is that leader only knows facts that was presented to him and even if he has some information about overspending on production, he could ;t look at that problem as professional as employee, who actually works on production of those products.In this case, leaders should to work as filters, choosing the best solution and employees should to present problem and show the solution as they are more informed and experienced in this field. In other hand, cultural intent should be mentioned as it plays a major role on how employee works. Referring to my country, we have strict rules at most of governmental and business workplaces, because from the times of the Soviet Union population of Astrakhan were used to make their best only when failure led to punishment of the worker.Even living in democratic country, direct and fast reconstruction to employee led innovation is not possible as it leads to problems of workers as laziness and procrastination. That s the reason why most of national and priv ate companies still don t give full freedom of action ND speech to employees, because before we need to have a good base and experience in this field.Overall, employee led innovation is becoming popular in nowadays as companies see the profit from that system of working. It provides workers with more critical and analytical thinking participating in company's life and giving a chance to improve the sphere, where they are good. However, before the start of process employers should to prepare their workers mentally, so they ‘II be able to work using that system with maximum effectiveness and profit.

Introduction to Roles of Army Engineers

CONTRIBUTIONS OF THE NIGERIAN ARMY ENGINEERS TO NATION BUILDING: CHALLENGES AND PROSPECTS INTRODUCTION 1. Nations of the world set objectives which they continually strive to achieve. These objectives which are regarded to be of benefit to the citizens of the country are collectively known as national interest. The extent to which a nation can achieve its national interest and indeed the influence it wields in the international community depends largely on its level of development. Nation building literally connotes national development.In a contemporary society, the concept of national development is directly linked to the general well-being of a state and its people. National development or nation building is predicated on indices such as economic stability, peace and security of the state. The essence of any government therefore is to provide security and welfare for the citizenry to achieve stability and peace. Nation building is a continuous process. It represents the process wh ereby changes are effected within any society to generate wealth, create economic opportunities and bring about peace, stability and security. . Over the last half century, some advanced countries like the USA, China and Israel among others have implemented various plans towards development. One of such plans is the use of their military in national development. Historically, military involvement in nation building can be traced to socialist countries like Russia, China, Cuba and Vietnam where the military was engaged in developmental activities such as agriculture and manufacturing.Later in the face of economic challenges, countries like Indonesia, India, Pakistan and Iraq also used their military in nation building through their military engineers for road construction and industrial development. This contributed to the development of their national economy. 3. A nation is defined as ‘a large body of people united by common descent, culture or language, inhabiting a particul ar state or territory’. On the other hand, building is ‘the business or task of constructing houses, factories, bridges and other large structures’.Hence, nation building could be described as a structural transformation of all facets of national lives such as economic, political, social and technological endeavours in order to make a nation more viable for development. 4. Similarly,in developing countries like Nigeria, it has become imperative that the military be actively involved in nation building to compliment the efforts of all other sectors involved in such activities. The NA through the Nigerian Army Engineers (NAE) has been in the forefront of this drive, in addition to its role of the defence of the territorial integrity of Nigeria.The NA also has the responsibility of aiding civil authority in disaster management or civil construction works which are normally carried out by NAE. However, the NAEhas the primary role of helping the NA to live, move and f ight. These include construction of roads and bridges, reconstruction and rehabilitation of facilities and water supply. For example, the NAE constructed the first road to Mambilla Plateau, of the then Northern Region now Adamawa State, in the 1960s. The Corps was also involved in the construction of a bridge across River Rima and the reconstruction of Ayakoromo town in 2010.When the NAE plays these roles, it is inadvertently contributing to nation building. 5. It is pertinent to state that NAE evolved from the Royal West African Frontier Force (RWAFF) which dates back to the early Twentieth Century. The NAE were part of the Royal British Engineers which surveyed and fixed the boundaries of what is now known as Nigeria with the neighbouring French and German colonies. In spite of the contributions of the NAE in nation building, the corps encountered some challenges while performing their functions.These challenges include dearth of equipment, absence of legal backing and shortage of manpower among others. It is against this background that this paper seeks to examine these challenges in order to proffer viable solutions for the NA in supporting the NAE towards efficiently contributing to nation building. It is written for the Director Department of Land Warfare in partial fulfillment for the award of Pass Staff Course. 6. The purpose of this paper therefore is to examine the challenges and prospects of the contribution of NAE to nation building.The paper will discuss an overview of NAE and the contributions of NAE to nation building. It will further appraise the contributions of some other countries to nation building in order to draw lessons for NAE. Finally, it will examine the challenges and prospects of the NAE’s contribution to nation building. This paper will however be limited to NAE‘s contribution to nation building in terms of structural constructions and projects. The aspects of peace and security as part of nation building will not be d iscussed. It is assumed that the reader is conversant with the concept of nation building.This would therefore not be discussed in detail. AIM 7. The aim of this paper is to discuss the challenges and prospects of the contributions of NAE to nation building with a view to making recommendations. ——————————————– [ 1 ]. 1.
