Mill’s explained "that this is the singularity is the basis in which you use to judge morality‚ with those being morally right being those that will manufacture the most happiness because in the end all humans seek happiness above everything else." He also argued that fame‚ money‚ and virtue could not replace happiness but could be used to obtain it. Mill’s believed that happiness is the guiding arch that drives

research and innovation is advancing our society at an incredibly rapid pace. However‚ while it holds many benefits‚ it also raises social and ethical questions the more our society depends on it. Ray Kurzwell (2005) focuses on the idea of the Singularity. The Singularity is the idea that technology will continue expanding to the point where human life will be completely transformed. This leads to the question‚ should there be limits on technological advancements? Although issues could arise with constant

Gravitational Potential Energy The two examples above illustrate the two forms of potential energy to be discussed in this course - gravitational potential energy and elastic potential energy. Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object. The gravitational potential energy of the massive ball of

As I read chapters 3 and 4‚ I was gripped by the idea of a big bang singularity‚ and immensely perplexed by the reasoning behind the uncertainty principle and quantum mechanics. Hawking begins the chapter with the epiphany that the “fixed stars” in the sky‚ aren’t really fixed at all. The stars are all constantly

Science Notes: Fundamental Forces of Nature All forces in nature may be classified into four types. The gravitational force holds together the universe at large‚ plus the atmosphere‚ water‚ and us to the planet Earth. The electromagnetic force governs atomic level phenomena‚ binding electrons to atoms‚ and atoms to one another to form molecules and compounds. The strong nuclear force holds the nucleus together. The fourth force‚ the weak nuclear force‚ is responsible for certain types of nuclear

According to general relativity‚ this was exactly the type of system that should produce‚ or radiate gravitational waves. Realising that the discovery of such a thing could be used to test Einstein’s bold prediction‚ astronomers started to measure how the period of the stars’ orbits changed over time. Over the next eight years‚ it was determined that the stars

The gravitational acceleration is 9.78 m/s2 at the equator and 9.83 m/s2 at the north and south poles (Masters‚ 2002). These different gravitational accelerations is also known as centripetal acceleration‚ and it has a minute change on different locations on the
