Quora answers need not be 100% correct answers. Compiled andposted by R. Gopala Krishnan, 79, on 18-09-2023. Q1 What is the impact of Reliance JIO on BSNL (state owned)? GopalaKrishnan,Former Asst General Manager, Retired at Bharat Sanchar Nigam Limited(BSNL)0y Firstof all B S N L is agovernment of India undertaking. Not state owned. There are manyprivate players now in mobile telecommunication field. Only difference with B S N L is itis more planned, in rural areas, North East region etc only B S N L mobile worksmore efficiently/only work. There is reduction in Landline requirement, because of the wider facilities offered by mobile phones. Buttowers and stations can fail during heavy winds and storms. Understanding this many customersand companies and institutions keep land phones 1–2 numbers now instead of 6–7numbers Q2 What seems easy but is really hard? A2 Komal Porwal, Life is not easy20h Doing household work like washingutensils, cleaning, and making food.My mother’s health has not been very good for some days, and the doctor hasadvised her not to do any kind of work and only take rest. So Myself and my sister have to do the entire housework. And for both of us, it wasa hell of a difficult task because our mother never burdened us with the work. She says that it's your age to study, notto do housework. Isee people always making fun of women because they only sit at home and donothing the whole day. But doing all this work also required hard work. We both are doing work, but we couldn'tmatch my mom’s level. Weliterally feel very tired, and interestingly, my mom manages to do all this work along withher job alone. Sobeing a housewife and doing housework is not as easy as it seems. You will onlyrealise the value of this work when you actually have to do all the work. And if she is doing all thatwork alone without a maid, then she surely deserves a bow🫡 Q3 What is the difference between fiber optic networks andcopper cable networks in terms of internet speed? A3 Rick Kaminer, Chief Engineer Wed Fiber as the name implies send lightsignals through a glass compared to copper that an electrical signal. Fiber signalscan travel many miles without interference or degradations, where copper CAT-6cable can only handle little over 300 feet or 100 meters. A big advantage of fiber isit can handle speeds 10Gb or 10,000Mb/s of data or more vs. copper which canpass speeds up to 1GB, depending on the distance. There is also a coaxial cablethat is copper, less prone to interference and can travel longer distances,however it is not an Internet Protocol signaland needs modems to convert to the standard method IP configuration. Clearlyfiber is the desirable method to send very high speeds data over long distances, but needs conversion to copper to accessmost equipment such as routers and http://computers.It isalso more expensive and more difficult to install. Q4 Did Lord Krishna or Balarama build the city of Dwaraka? A4 Yash Sandhu, Love to explore Vedic knowledgeand conclusion. (Love) 23h Yes, in Mathura city every devotee oflord is disturb by kans and manyfamilies lost their near once at that time, because of this they have badmemories for that place and again and again Mathura was also attacked manytimes, so to save hisdevotee krishna ordered vishvakarma (son of lord bhrama) to build a beautiful place for his wives and devotees Actually, Krishna’s will is not for him butfor his devotees. Now at Dwarkamany fallen souls are dileverd to the transcendental level, when Krishna was leaving for hisvaikuntha, then he transferred his all divine power to trivikram idol.So, to have a holy glimpse of lord one should visit Dwarka. This land for Dwarka Krishnatake from lord of sea(varundev), then Krishna promise that after his pastime hewill return this land again to sea, becauseof that Dwarka sank inwater by the will of krishna, he just made curse of Gandhari as a way toend his pastime and to return land to varundev. Mynote- From the answer it is to be presumed that as Lord Krishna desired tobuild the city of Dwaraka. Q5 Is it true that humans didn't always sleep for 8 hours everynight? A5 Ian O'Grady, Studied TV and FilmProduction21h In the Middle Ages, people would sleeptwice, which was known as thetwo-phase or biphasic sleep. Peoplewould generally go to bed at 9 pm and then wake again at 11. For about two hours, they would work onthe farm or clean the house. This was also a time to socialise and evenconceive children. This is because familiesusually shared one bed with the kids, and it was even common for friends andeven passing strangers to all sleep in one bed. Sleep etiquette was applied, and to make things less awkward, physicaltouch and excessive movement were seriously frowned upon. Q6 What is one fact that you know is true but still blows yourmind? A6 Sunny Dhondkar, Writer. IIT Bombay, MECE.2y My note- I have deleted many difficultmathematical items notmuch required to understand the answer. Whenyou spill water on your shirt, it looks darker than the rest of the cloth. Whydoes it happen? Thelack of awareness regarding this question still blows my mind. This phenomenon is so regular thatmost of us ignore it as if it’s a universal truth of nature. Youdon’t question, others don’t answer. Thisis what we experience daily without giving a thought: If water spills on your shirt → Wet area gets darker Youmight ask why this kind of unawareness among people blows my mind. People areunaware of lots of things that go unnoticed. Answeringto that: This phenomenonlets people notice when you pee your pants, causing a load ofembarrassment still, you don’t know the mechanism behind it. Isn’t that mind blowing? It’snot just your shirt or your pants that show this behaviour. All of theso-called daily life materials become darker when they get wet. Takea concrete road for example: Thewalls of your house: Ifsomething gets wet, it is bound to get darker. This fact is “usual” to thatextent, nobody questions it. Getting to the physics behind it. Let’s assume that you are wearing ablue shirt.What makes the person standing in front of you know that the shirtyou’re wearing is blue? Itis done by the absorption of electromagnetic waves by the material of yourshirt. Radiation from a source, say sunlight,strikes on yourshirt. This electromagnetic radiation is a set of distinct wavelengths. Visiblelight is a small part of the entire set, which is known as the ElectromagneticSpectrum. Different colours corresponding to different wavelengths in the visible light part of theelectromagnetic spectrum. Afterstriking on your shirt, waves with wavelengths not lying in the region of 380nm - 500 nm, from the visible light part, are absorbed by the material of yourshirt. The remaining waves (ofwavelength lying in 380 nm - 500 nm) get back to your eyes. These waves aredetected as blue… by your eyes. Thesituation with no water spilt on your shirt Butthat’s not the case when water is spilt over your shirt. Light has to travelthrough a completely different journey. Thisis what happens: Thesituation with water spilt on your shirt Lightstrikes on the surface of the water and undergoes Refraction (because therefractive index of water is greater than that of air). Ontravelling further, it undergoes Reflection after striking on your shirt. Some part of the light is absorbed and the remaininglight (with the wavelength of the blue region) goes further. Onreaching the boundary of water, if the angle of incidence is greater than thecritical angle, light undergoes Total Internal Reflection. So, it bounces backto the water medium. [Thevalue of the critical angle is determined by the Arcsine of the ratio ofrefractive indices of the two corresponding mediums — here, air and water] We know that the intensity of lightdecreases when it undergoes absorption. So, when light strikes on the surfaceof your shirt, again, its intensity is reduced. Onbouncing back to the surface of the water, it refracts further (if the angle ofincidence of the light ray is lesser than the critical angle), and reaches youreyes. Your eyes interpret this as the darker version of blue. So,the next time your friend scares the sh*t out of you and you pee your pants,curse total internal reflection. P.S.Youcan try standing in the air with a greater refractive index, in case you feelyour bladder is full. Q7 What is the interesting e story of a hardworking woodcutterwho can teach us a lot. A7 Kaushal,9h A village boy in Greece used to earnhis living by cuttingwood in the forest and selling it in the market of the nearby city in theevening. One day a learned manwas going from the market. He saw that the boy's bundle was tied veryartistically. Heasked the boy, “Have you tied this bundle?” Theboy replied: “Yes, I cut wood all day long, bundle it myself and sell thebundle in the market every evening.” The man said, “Can you open it and tie itagain like this?” Yes, see this” – saying this the boy openedthe bundle and tied it againin a very beautiful manner. He was doing this work with great attention,dedication and agility. Seeing the boy's concentration, dedication and artistic way ofworking, the man said, “Will you come with me? I will get you education andbear all your expenses.” The boy gave his consent after thinking andwent with him. Thatperson made arrangements for the child's residence and education. He himselfused to teach him. Within a short time, the child assimilated higher educationon the strength of his dedication and sharp intelligence. When he grew up, this child became famous by the name of the great Greek philosopher Pythagoras. The good man who recognized the seed of greatness lying within the child andnurtured it was the famous philosopher of Greece, Democritus. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
