GENERAL SCIENCE Dearfriends, Today I wasjust going through my certificates to put it in a new Polythene folderpurchased. I found I have answered a paper on General science in the first yearof my BSc examination also.
On those daysthe brain never tried to think how Physics, Chemistry, Botany and Zoology couldbe together called General Science. I simply accepted they together calledGeneral Science. Today at 66, I can grasp these subjects formed the science inGeneral of the nature and oriented to different aspects. Sometimesthere used to be mingling and diverging also between the subjects. All these subjects are science-in simple meaning they are oriented to know why and how.. Recently Iread elsewhere brain grows at all ages but sometimes concentration could bedifficult as age advance. I felt concentration depended on the interest to thesubject and time studied. This interest had a part at all ages. Let me makesome pondering on General Science. Sincerely, Gopala Krishnan23-9-2010 Reposted on 3-1-2021 after editing and updating R.Gopala Krishnan 1. General Science Though thesubject was called General Science whenI was studying in the college respective portions of Physics, Chemistry, Botanyand Zoology were taught by the respective sections of the department because thoselecturers have studied more and could present well. They have better knowledgethan good knowledge. Other thanGeneral studies used to be a single book, chapters on the different subjectswere grouped together. While in middleschool classes the same teacher could teach all, even at high school level theteachers used to be different. At middle school level the teacher could teachall just like an MBBS doctor doing all general treatment. 2. Laws of Physics. Physics dealtwith physical qualities of nature. Though I studied Raman Effect why the sky isblue or deep water is blue, an understanding of the physical qualities came verylate on deep thinking. So it was a nature’s science also. Today I canwell understand why the apple fallen on ground is a physical law and also atopic of Botany too. The topic of botany is a ripe fruit would not hold toplant since it has to falldown and again grow for propagation. The topic of physics is afalling object has a velocity and this velocity is an important criterion. 3. Pakku vetti (Aracanut cutter) On olden daysaracanut was cut in to pieces after removing skin using Pakkuvetti. Chewingbetel was considered a good habit. Offering betel was considered an action ofrespect. This pakkuvetti is made of goodquality iron. The principle of functioning of this cutter, which can cut the nutwith very less effort, is physics law. But the material should be harder oneand not brittle is a chemical identity of material. We cannot make an aracanutcutter with brass or silver or bronze or copper. Now too cutting machines aremade of hard material. While a ripeplantain can be broken in to two with hand an apple cannot though both arefruits. 4. Gold mining We know allmetals are from the mother earth. Externally seeing we cannot say earth is ametal. Metal is not available as a block with in earth also. Here theprinciples of physics to locate the area where the earth has more contents ofmetal , then applying different aspects of chemistry to filter them and get andmaking to block. A new science called Geology combining the two aspects of Physicsand Chemistry was formed. As our searches go, new and new sciences are coming!! We have learntgold, iron, silver all were used during the epic periods. Can we have any guesshow this science of producing them or finding them was called then? Was itcalled as science itself? 5. Trees, plants and life While studyingBotany I have studied plants have life. It is a living being. All living beingsneed not move. It was very difficult to grasp the plants have life and hence itgrow, provide fruits for propagation as like humans and animals propagate andas like other being they too have a natural death. Birth and death for allplants, trees and creepers. In our life period many plants germinate from theseeds, grow, flower, mature, give fruits and after some time dry out. So being avegetarian means, we do not kill animals for our food. That is all.. We are eating, plucking orcutting a living plant. 6. Chemical composition of medicines If we see anyallopathic medicines we can see the % of different chemicals used. This medicinecan cure a disease of human .The same way vetinary medicines can cure theproblems of animals. How the chemical cures an ailment? So the human or animal body accept chemicals.In fact chemical deficiencies are made up or required chemical changes are madeas required. 7. Insulin What actuallyis INJECTING insulin? It is not a chemical. Insulin is taken from the pancreas of a goodhuman and then developed in a similar method of cloning!! So while I injectinsulin, is it not a living part of body or anything with life? Update- Nowwith synthetic insulin also the case is not much different –made from E-coliBacteria. 8 Laser surgery or pinhole surgery Whereas thesurgery is a point of zoology, the laser beam and its use is a principle ofPhysics. Hence in nature all these sciences existing or newly developing havesome interesting links. 9. Where ever and when ever There is abeautiful saying some people bring happiness WHERE EVER they go. If you changethat where ever to whenever it will be some people bring happiness WHENEVERthey go. It simply means some people’s presence is liked and some people’sabsence is liked. Can we imaginethe sciences behind it? It can be related to scientific sides of physics,chemistry, botany and zoology or all? -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
