FILTER AND NET Dearfriends,
I wasthinking about selective nature of people. It is some sort of filtering. InTamil there is a saying- Dushtalae kantal Doorae doorae, Ishtalae kandal Kootaekootae (Go away from bad people and get attached to good people). Thisselective nature only helps for wellbeing of the individual. This is a mental filter. A filteralways permit passing through something and does not permit other things. Intechnical equipment the filter could be integrated circuits. A software programlike antivirus loaded in a computer does not permit any program containing virus from an internet websiteor not a familiar programme . Very often we may see when down loadingattachments- Authenticity not known -Whether to down load - Permission asking. Sometimesit might be the one you may be trying todown load. When we load an antivirus program to computer, it is stored in an integratedcircuit. In physical sense it is somesort of net. In coffeefilter, the netting is by drilling small holes in the bottom of the top vesselin which not fully ground coffee powder is filled. It has a tight cover. It permits the decoction from the bottom ofthe vessel to drip in to another vesselfitted to it only when boiled water/very hot water is poured in the coffeepowder vessel and closed. In mosttea filters it is a thick filtering mesh cloth attached to a strong ring withhandle. It permits tea decoction tofall in to a vessel. The tea powder is simply added to cloth. Once a while teapowder is added again. After preparingabout 15 cups of tea, the net is cleaned pouring out used tea powder. This method of adding more powder is not possible for preparing coffeedecoction. Something similar to front loading and top loading washing machines. Thedifference between the two decoction is coffee powder is obtained by grindingthe dried coffee nut and tea powder is obtained by cutting smaller the tealeaves and dried and powdered. Though in both case filter is in action, thetype varies. Consideringthe Vati katti (Plastic/stainless steel semi spherical vessel), it drainscomplete water from the articles put in to it. It can be cooked rice, cutvegetables or cut leaves like spinach. The aboveis told for different types of filtering methods. I will continue with filters. Sincerely, GopalaKrishnan 28-11-2021. 1. Eye filter When thebank cashier makes payment of a cheque/withdrawalform filled, the official first select better notes and then count and give it.The selection of better notes for distribution is done with a selection througheye. The samebank officer employs adevice to check the genuineness of the currency when deposited. He ensures all details enteredin the form are correct. The currency may appear brand new. Here the filtersemployed are physical and technical. Nowadaysthe banks ensure the currencies supplied are mixed bundles with old and newnotes. Nowadays new currency is given only when the bank receives from chestonly new currency. Our eyes areprovided with eyelashes eyebrows to filter dust coming to eyes. Closing of eyeswhen wind blows with dust or anything hot is not a voluntary action. Nerves from the eyeare directly connected to brain. 2. Ear filter The earfilter is the hairs growing inside the ear. It protects dust not entering ear which couldaffect hearing. The wax inside the ear is for keeping smooth the ear. Excesswax rolls out. Ear controls human walking also. Keeping both ears fully closed one cannot walkwith balance. Deaf people walk perfectly because their ears are not closed. I havelearnt lighting is to be feared, thunder is only the following sound. Lightningonly affects since it carry electric charge. Though Iaccepted it even during my college days, now I have a doubt in my mind. Does thunder sound having higherfrequencies does not affect the ear? Similarly fireworks which makebigger sounds. Is it not due to this many close the ears with hands? The earfilter too goes in to action before the eyes. A person waiting for a bus firsthears the sound, of bus by filtering the sound heard, then look for it. 3. Nose filter I thinknose filter is having more a physical filter with in nostrils with tiny hairs.It prevents dust entering while breathing. Rather than this, good and badsmells are very much filtered by the nose. In reality first nose filters a foulsmell and then the eye go in to action to realise the source. A mouse deadand decaying in a road side is first detected by the nose and then the eye goesin to action to see it. Smell sense go faster than eye viewing!! Somepeople trim/pluck the overgrown hairs in the nostrils. Olden day’s barbers didit with small scissors. Now we ourselves trim the extra visible growth. Pluckingbefore others is not a hygienic practice. But still we can see some doing. Itis an involuntary action by hand, not able to control by mind. 4. The tongue filter Thetongue has two functions one in tasting and consuming and the other assisting intalking. Thetongue filter everybody correctly usesfor the first part. Everybody is attracted to the good taste. I have read in kidshealth.comtongue filter synchronise with nose filter. If something does not smell good,the taste would not be felt good at all. Thesecond function of tongue is for talk associating with throat. Here for manythe filter action is very weak, and not at all controlled creating allproblems. The net employed is expanding is the problem. It is the common natureof many talks something in anger and later regret for the words. But the woundcreated cannot be healed. The spoken words cannot be taken back. It is a mentalfilter. 5. The mouth filter A filterin mouth is for selective and controlled consuming of food. But mouth filter fails tofunction so many a times. Oneinstance is quickly eating clearly knowing the consequences. A limited quantitywhich could go with in mouth only has tobe taken at a time. But when one is hungrier, mouth fails to function so. Theperson eats as if the food would vanish if not consumed in minutes. Thesecond one is while allowing the liquid food. It simply allows though there isa limit with throat. We can see many children consume cool drinks and splitout, not able to keep with in mouth. If we take hot coffee, it is the throatfirst sense and not mouth. Withcovid 19, everybody wears mask. It is toprevent covid virus not entering through mouth. Use and throw masks priced verylow prevents person using same mask repeatedly without disposing. 6. Kidney filter Kidney isa most important body part- It is a real filter inside the body in the hiparea. There are two kidneys on either side. Similar to we have two eyes forperfect seeing, two ears for perfect hearing and balancing, two nostrils forbreathing and smelling, we have two kidneys. Thekidney is the size of our fist- a big organ. Both kidneys need not be of thesame size. There couldbe marginal variations. If one takes scan, one could find himself thevariation. Weknow any physical filter if not wellcleaned with sufficient water after some time solid particles might stickto and would not be much effective indue course of time. If it is continued? Just likethe towels become rough and does not absorb water in course of time if notfrequently cleaned, the kidney fail to filter unless cleaned with SUFFICIENTwater intake. Other things are also there I haveused the term sufficient water. More water means more filtering action andbeing an organ it would get exhausted.This is the reason thedoctors suggest a specified quantity of water. Diabetics are advised to consume limitedquantity of water. I have read articlesalso from famous doctors from Apollo Hospitals in this regard. Whilekidney becomes very weak, from a suitable donor, with all tests positive, fromthe donor a kidney is removed and stitched to a weak kidney. The weak kidney isnot removed. Because, if new kidney fail after healing, a condition should notcome- “Ullathumpochhuda, nallakkanna”(Weak kidney may function at least 10%.) A weakkidney may function somewhat normal even when it could function only up to 25%. 7. Brain filter I thinkbrain is the biggest filter and has sub filters. It ensures to keep informationnecessary and leave the others. What all information to be preserved isdepending on the individual. Hence the brain filter vary in function depend onthe individual. Ateacher may keep information for teaching, a student may keep information onlesson, a cooking woman may keep information about cooking items and a workermay think about his tools. These are all sub filter action with common information stored for everybody.Varied dishes are prepared by women thinking about it in previous day itself,and make public if necessary in the morning. Retrieving the informationstored is by another sub filter. This sub filter expands and reduces and sometimes become effective andsometimes not effective. While writing this posting, the word SCAN came to mevery late trying best to retrieve. This sub filter is special. Icannot recollect what the dishes were before a week in the afternoon meal. ButI can recollect the special butter roast taken before a month in a hotel atBangalore including its shape, sweet sambar and even where I sat. I can recollect where I havestood and took photograph of Tajmahal before 20 years. But I am not able to recollect where exactly I kept the scissorsafter cutting medicine strips. I canrecollect the colour of my autograph book in the college, the lines written by mydearest friends. I do not recollect how many shirts and pants are there forme!!! A willconclude this part with a slightly humour point. My wife at anymoment recollect specific time and dates and locations I roughly behaved after marriage counting1,2,3,4,5,..Instances . But shehas least recollection of any such misbehaviour or disobedience or irritatingbehaviour from her part at all. Leaving them, she has least recollection when Iappreciated or rewarded or admired her intelligence or positive aspects. I hope this posting is interesting. I willcontinue with in my next posting. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
