The Cycle of Life

At Sonnet 73, "When you may see it in me" the focus is on the narrator's concern about aging and imminent death. Each quart line expresses this in different ways and ties the life stages of the narrator to various analogies indicating the transmission of time in nature. The time from several days to several minutes from the season has been greatly shortened. As time goes shorter, the speed at which the narrator approaches death will be faster. Finally, death is imminent, the narrator is obvious, and that is obvious for both audiences and readers.

Summary of Lucretius' life cycle and fear of death: In De Rerum Natura III 963971, Lucretius believes that death should not be afraid of death, as death is an essential part of the natural cycle of life and death. Apart from Martha Nussbaum, this argument has rarely attracted philosophical attention and he claims that it is very powerful. But the view of Nussbaum is unsustainable and I offered my own reading. As I mentioned, I agree with Nussbaum that the discussion of the life cycle is quite different from the well-known Epicurean debate. It starts not only from different premises but also from entirely different discussions. However, as explained by this, this is very problematic. It relies more families of Stoic 's schools than Epicurean' s ethics, and Lucretius' s appeal to nature in this discussion is inconsistent with his argument elsewhere in De Rerum Natura. Instead, it deals with the destructive attitude towards human life and fears death. 1

Waterfall life cycle: The waterfall life cycle is the most familiar and classic lifecycle model. It is sometimes called classical life cycle or linear order model. This is the simplest life cycle, very easy to use and easy to understand. In the waterfall lifecycle, each phase needs to be completed before the next phase begins. Each stage is independent and there is no overlap. V-shaped model: The V-shaped model is very similar to the waterfall model's lifecycle, but the test is carried out in the early stage of the life cycle, not the waterfall model. Like the waterfall model, the V-shaped model is also a sequential loop, and a new phase is started only after the previous phase has been completed. Each development phase matches its own test phase, according to the requirements of system test, advanced design, integration test, low level design, and unit testing. For systems requiring high reliability, a V-shaped model is very useful.
