Physics of the Atomic Bomb :: physics atom atomic bomb nuclear a-bomb

The atomic bomb (also known as the atom bomb, A-bomb , or nuclear bomb) has a destructive power created by the fission of either uranium or plutonium. But, not any isotope of uranium can be used. Only U235 is used in the production of an atom bomb. U235 is very hard to come by due to the fact that it is only present within 0.7% of all natural uranium. In order to separate the U235 isotope from natural uranium a process of enrichment is used. The uranium must be enriched to 90% for actual use in a bomb. The enrichment process is complicated due to the fact that the uranium isotopes are practically chemically identical. This means that the different isotopes cannot be separated with just an easy chemical reaction. The isotopes must be separated by exploiting the little mass difference between the isotopes. There are many different methods used to separate these isotopes a couple of these are the commercial-gaseous diffusion process and the centrifuge process. Another method of separation is the Electro Magnetic Separation process. This enrichment method was created by E.O. Lawrence. It involves passing uranium ions through a magnetic field which causes the U235 ions to separate and take a different path than the U238 ions. Following this collectors are used at the other end of the semi-circle to capture the separated U235. Fission of U235

Christian Worship Early Christian Practices Essay

Zoryana Nichipor Christianity Western Culture Box #390 Word Count: Book Review of Ancient Christian Worship: Early Christian Practices in Social, Historical, and Theological Perspective Throughout this book, Andrew B. McGowan thoroughly informs us on each cultural background and formation of the different types of acts of worship throughout the early Christian church. We see through this information that the way the Church worships has evolved into something completely different from what it once was. In one form or another we are forced to appreciate how the early Christians worshipped and, I would even assert, are challenged to bring these traditions into our own mentality of worship. If we are to look to the New Testament and how worship is referred to, it is â€Å"a great deal about ethos or a Christian way of life, but relatively little about the specifics of distinctive liturgical practice or performance.† In chapter one of McGowan’s book, we see a compare and contrast given with how the early church worshiped more communally as opposed to how we worship today; which is more aesthetic and internal. McGowan reiterates numerously that worship in the New Testament is a subject of service, reverence and ethics. â€Å"They were not merely one sacramental part of a community or worship life but the central act around or within which others— reading and preaching, prayer and prophecy— were arranged.† The New Testament was in the setting of a very communal culture.
