When should we trust our senses to give us truth Analysis Essay Example For Students

When should we trust our senses to give us truth? Analysis Essay Rationally, the one we see magnified through a microscope is truer as it offers an even closer look at the paper under study than our eyes alone. Therefore it can be deducted that a microscope with a further increased magnification will reveal more truth. So if what we see with our eyes is not true and what we see through a microscope is also not true as there is always a possibility of an even stronger magnification then, what is true? The answer is not very easily produced as an unconditional truth is not always possible and thus we have to rely on a combination of our senses and anything else that would contribute to the journey for truth.

Analysis specifically for you for only $16.38 $13.9/page Order now All the arguments regarding our senses and if they should be the vehicle used to drive us on the passage for truth revolve around the question: If I cannot trust my senses, then what do I trust to provide truth? Our senses are the foundation and basis for everything in our lives. From the moment we develop a brain while in the womb of our mothers to the time when our feeble heart stops beating, we use our multiple senses for everything. They act like a beacon illuminating the dense darkness all around us and guiding us while we are living and breathing. The exploration for undisputable truth is accented by hopelessness. We cannot fully rely on something as concrete as our own senses. This leaves us without dependable tools that we can implement to support us in this difficult process. As unreliable as our senses are, they should not be the deciding factor of truth. They are fundamentally variable and simply unstable but, they are all that we have. We should however, trust them to allow us to grasp the world around us be it not always true. Obtaining the evasive truth is impossible for us as human beings but, the unfeasible task should nevertheless be undertaken purely for the sake of maybe one day being a step closer.

Stink Bugs, Family Pentatomidae

Stink Bugs, Family Pentatomidae Whats more fun than a stink bug?! The insects of the family Pentatomidae do, indeed, stink. Spend a little time in your backyard or garden, and you are sure to encounter a stink bug sucking on your plants or sitting in wait of a caterpillar. About The name Pentatomidae, the stink bug family, comes from the Greek pente, meaning five and tomos, meaning section. Some entomologists say this refers to the 5-segmented antennae, while others believe it refers to the stink bugs body, which appears to have five sides or parts. Either way, adult stink bugs are easy to recognize, with wide bodies shaped like shields. A long, triangular scutellum characterizes an insect in the family Pentatomidae. Take a close look at a stink bug, and you will see the piercing, sucking mouthparts. Stink bug nymphs often resemble their adult counterparts but may lack the distinctive shield shape. Nymphs tend to stay close to the egg mass when they first emerge, but soon venture out in search of food. Look for masses of eggs on the undersides of leaves. Classification Kingdom - AnimaliaPhylum - ArthropodaClass - InsectaOrder - HemipteraFamily - Pentatomidae Diet To the gardener, stink bugs are a mixed blessing. As a group, stink bugs use their piercing, sucking mouthparts to feed on a variety of plants and insects. Most members of the family Pentatomidae suck sap from the fruiting parts of plants and can cause significant injury to the plants. Some damage foliage as well. However, predatory stink bugs overpower caterpillars or beetle larvae, keeping pest insects in check. A few stink bugs begin life as herbivores but become predators. Life Cycle Stink bugs, like all Hemipterans, undergo simple metamorphosis with three life stages: egg, nymph, and adult. The eggs are laid in groups, looking like neatly arranged rows of tiny barrels, on stems and the undersides of leaves. When nymphs emerge, they look similar to the adult stink bug but may appear rounder rather than shield-shaped. Nymphs go through five instars before becoming adults, usually in 4-5 weeks. The adult stink bug overwinters under boards, logs, or leaf litter. In some species, the nymphs may also overwinter. Special Adaptations and Defenses From the name stink bug, you can probably guess its most unique adaptation. Pentatomids expel a foul-smelling compound from special thoracic glands when threatened. In addition to deterring predators, this odor sends a chemical message to other stink bugs, alerting them to danger. These scent glands also play a role in attracting mates and even suppress attacks by harmful microorganisms. Range and Distribution Stink bugs live throughout the world, in fields, meadows, and yards. In North America, there are 250 species of stink bugs. Worldwide, entomologists describe over 4,700 species in nearly 900 genera.

Pilot Study - Plan for data collection Research Paper

Pilot Study - Plan for data collection - Research Paper Example Teachers are faced with a number of factors that make it difficult for them to implement their RET experiences in the classroom. Therefore, it is important to find out how to support teachers in their classroom after completion of an RET program, with the goal of improving student learning. As such, this paper documents a plan about how to do some pilot testing of data collection related to the RET program. Basically, preliminary data will be collected directly from the participants who have been involved in this program. The three methods that will be used to perform this task include the following: interviewing, observation and reading their teaching plans. The interview technique that will be incorporated in the primary research for this study will be face to face with the participants. The interview question design and set up would be maintained at a simple level that is easy to understand by the participants in the study. The questions that would be used are open ended and exploratory in nature and focus on gathering information on the main topic within short time period so that the respondents are given the opportunity to respond quickly without wasting their time and efforts. The main purpose of interviews is to discover the opinions and views of people who are involved in the study. According to Oppenheim (1992), the main advantage of interview technique is that first hand information from the participants about their views and perceptions towards a certain subject are explored. This helps to generate more knowledge about a certain subject area under investigation. The other advantage of the interview technique is that they are unbiased since they involve direct interaction between the interviewer and the interviewee (Struwig and Stead, 2004). This will help the interviewees to express their opinions about their perceptions towards the RET
