CULTURAL QA 09-2022-16 BEING ACOMPILATION THERE MAY BE ERRORS
Q1 How doeschanging the fan speed on a ceiling fan affect the amount of electricity used? A1 GopalaKrishnan,Former Assistant General Manager 1996-2004 at Department of Telecom(1966–2004)Just now While increasing or decreasing speed of a fan, the resistance is increased or decreased in arheostat. We know I =V / R . When speed is very low, R is more, voltageis constant, so I will be low. When speed is increased R is reduced and I ismore. But this increasein R is not much, hence increase of I is marginal. Q2 IsIndian railways changing for better? A2 SaurabhKumar, Lives in Patna, Bihar, India (2020–present)1h Yes, They are. In 2020 me along with my family were travelling fromAhmedabad to Patna by Azimabad Express (12947). As soon as the train left the station, a wash basin outsidebathroom started leaking and water was coming into the coach.Water comingsomething like this: We called 139 to register a complaint. And to my surprise, within 5–10 minutes,2 guys probably fromthe cleaning staff came into coach asking about complaint. We told them the problem andthey apologized for it. They fixed the problem and then asked us torate the service and marked complaint as resolved. We were very happy to seesuch a service from railways :D My note- Because allthese works are carried out in contract. Consider the condition of coaches likein double decker orSatabdi. Push back may not be working, meals tray closing is missing and toiletis not in good condition including the lock. Side glasses are partially crackedand not replaced… Q3 What arethe really dirt-cheap travel destinations for Indians? A3 RudraChauhan, Sep 2 I wouldn’t talk about dirt-cheap travel destinations forIndians but the places that I am going to talk about are indeed very budget-friendly,and it won’t break your bank. The list goes like: Pondicherry: Thisplace comes at first in my mind when we used to talk about travel destinations. I love this placebecause of beaches, and I adore those ancient French colonies. It is reachableby air, train, and road. The best time to visit is in the month of October toMarch. The average cost would be somewhere between Rs.500–Rs.1000 per day. My note- Except the Adyaranandabhavan, no goodvegetarian restaurant is not there. It is always crowded and quality too isjust OK Pushkar: Do you wantto get a religious vibe? Explore this place has a quite popular Jagatpita Brahma Temple that isdedicated to Lord Brahma. The average cost of food and stay would be aroundRs.1000–1500 per day. Kodaikanal: This placehas all my heart. This place is full of scenic views, and it is popularly known as Princess of HillStations. This place is not as crowded as Ooty. The average cost of food andstay would be around Rs.1000–1500 per day. Darjeeling: How aboutwaking up to the sunrise of Tiger Hills and sipping a hot cup of special Darjeeling tea. Thebest time to visit is in the month of April to June, and October to January.The average expense comes to be around Rs.1000–1500 per day. These are some budget-friendly travel destinations that youcan explore and I bet you won’t regret your decision. Q4 Howoften should we service our air conditioner, and what does servicing involve? A4 Graham L, BAin Computer Science & Mathematics, The Open University (Graduated 1990)Tue Most recommendationssay twice per year, once in the springtime and once in the Fall. >From my experience it is usual to do the following services(at least in my >area): Check refrigerant (often called Freon) for leaks and correctpressure. Ensure the outdoor compressor is starting, running, andstopping effectively and is free of debris and obstructions to good levels ofairflow through it. Check for presence of mold. If you have a heat pump, will check the reverser valve isoperating properly and the heat can be felt in the room vents. Check/change air filter in the furnace and the presence ofmold on the chiller pipes. Remediate as needed. Check operation of ventilator system (if fitted). Clean and washout the condensate pipe and check where itdrains to is secure. Provide advice on non-maintenance items that may be showingsigns of wear and advice on health and safety for the AC systems whenappropriate. Those checks will increase the likelihood of a safeenvironment for your family that will work throughout the cold winters and hotsummers. My note- Most serviceengineers advice to run the AC whether required or not for half an hour in afortnight so thatproblem can be set right. With split AC, even after providing net over the unitfrom some where sparrows, squrriels getin and lay eggs and infants grow, obstruct the external fan working with theirnest etc. Some times cats deliver near the external units creating foul smellsof meat taken and given to kittens. Q5 Why wasthe concrete made by the Romans more than 2,000 years ago stronger than the oneused today? A5 Bob deWitt,Art History Professor, Utah Valley University Aug 8 Roman’s were lucky.Roman concrete is amazingly strong because of its chemistry. Modern-dayconcrete is typicallymade of ‘Portland cement’ that is then mixed with water and aggregate (likegravel). Portlandcement-based concrete does deteriorate over time. A common attempt to make it strongeris to embed steel reinforcing rods in it. This does increase its‘tensile’ strength considerably—far beyond anything that Roman concrete coulddo. For instance, Romanconcrete could never be used for a freeway overpass span like is commonly usedtoday. However, steel reinforcement hasone major drawback: steel rusts. This not only weakens the material but it also expandscausing cracks and other weaknesses in the concrete. So, one of the reasonsthat Roman concrete structures have lasted for millennia is that the Romansonly used it in so-called ‘compression’ mode, never in tensile mode (in other words for structureslike columns, arches, and domes—never for horizontal elements like beams). Because concrete is only used incompression, the more weight it carries, the stronger it becomes. Perhaps the most important reason Roman concrete is sostrong, though, is that itis made with ‘pozzolana’ ash instead of Portland cement. Pozzolana ash isvolcanic ash and the Romans were incredibly lucky in that pozzolana-basedconcrete actually grows stronger with age, especially if it has beenmixed with sea water. This has been recently been shown through studies made atthe University of Utah. Surprisingly, mixing pozzolana ash with sea watercreates something called aluminous tobermorite, a rare silica-based mineralthat's actually very hard to make in the lab, but is abundant in the ancientRoman concrete and causes the concrete to grow more rock-like with age. This not only makes ordinaryconcrete structures stronger, but it works like a miracle with underwaterstructures like harbor foundations. The pozzolana not only hardens underwater, but the sea watermakes the concrete harder because the aluminous tobermorite actually grows inthe concrete thanks to the sea water sloshing around it, slowly dissolving thevolcanic ash within and giving it space to develop a reinforced structure fromthese interlocking crystals of aluminous tobermorite. As a result, according to theresearchers: "The Romans created a rock-like concrete” by using pozzolana. Of course, that stillbegs the question of why are Roman structures such as the Basilica ofConstantine in Trier, Germany still standing when there wasn’t any sea wateraround to use? There are otherreasons for that, such as the technique they used for such structures, calledopus testaceum, as seen in the graphic below: This is where the builders would created two walls of brickspaced a two or three feet apart, and then pour concrete (which had been mixedwith only a bare minimum of water) into the ‘form’ thus created, and firmlycompact it (which made it stronger). As well as simplymaking walls really thick….Anyway, there you go. Those Romans just keptthinking of everything…. Q6 Asidefrom speech and clothing, what separates humans from other animals? A6 ClaireJordan, Degree in biology and folklore; programmer, shop owner, secretary onnewspaperTue Better dexterity andthe ability to throw well. An unusually upright bipedal posture which frees upour hands to do these things. But speech is the reallyimportant one. Otheranimals have languages but so far as we know none of their languages are moresophisticated than that of a human toddler (except that crows have a remarkableability to describe human faces to each other, which we haven’t decipheredyet). Complex speechenables us to construct elaborate stories which are used as teaching aids (weknow that bonobos, for example, can gossip but they can’t composesagas so far as we now), and it lets us outsource our intelligence and build onthe discoveries of those who came before us, without having to literallyre-invent the wheel in every generation. Q7 What isthe difference between "evolutionist" and "biologist"? A7 KenSaladin, Former professor of histology (microscopic anatomy)1h Biologists are those whoscientifically study living organisms An evolutionist (inone sense) is a biologist whose central interest is the evolution of livingorganisms. In anothersense, it can mean a person who builds a philosophy around evolution, likeJulian Huxley. Q8 Can youeat cooked rice that was left overnight?

I am trying to bring it to 65kgs for thelast 3 years, but not achieved, but I will do it before December 2022. Most of the people reading this would have concluded that Iam a boring person, but I enjoy living life of my own. We need to accept“Destiny" then it is easy to manage life. Oh…I forgot to mentionone thing, every 45days I am out for 10 to 15 days, either to friends place outside Bangalore orSister's house outside Bangalore or on a short pilgrimage and the sorts.I always enjoy travelling, not able to stay put in one place for long. So, thisis the way of Life I am bestowed with. Once again it is “Providence" - my sole objective, do not wantto be a burden on anyone. Hopefully, my “Sai Ram" will show me the way. MyBest Wishes. Q10 Does theheat from your house go anywhere when you turn on the air conditioner? A10 Dean Hough,Former Electrical Engineer \ Computer Science21h Yes, the heat from your house gets transferredoutdoors. If you putyour hand next to an air conditioner compressor running outdoors you will feelthe heat being expelled, or rejected, from the fan blowing air across theradiator. Thecompressed refrigerant is hot because it’s in a liquid state and this heat iscooled off through a radiator. Then the cooled refrigerant flows tothe evaporation coil located in your home where the refrigerant evaporates to agaseous state and it becomes quite cold. Air is blown across that evaporation coil to cool yourhome and the evaporation coil is just another radiator except this radiator isabsorbing heat because it’s cold. My note- While theairconditioner warms the room/ hall/ building a lot of warm air is sendout which is carried away by wind if blows. One canobserve this very warm air if one go through the area where coolingsystem is provided for a building All the above QA are from Quora website on 15-09- 2022.
