CULTURAL QA 04-2023-05 Q1 Whatis the news item- Discovered a pond never seen by man
A1 Alessandro13,Sun It has beenisolated for hundreds of thousands of years. No one had ever seen it yet, then in May 2020, a small bodyof water was discovered at Carlsbad Caverns National Park in New Mexico. It is located in one of the largest and deepest caves inthe world and was discovered at a depth of 213 meters.Bacteria that live in water have "evolved without human presence". The body of water is surrounded by white rocks which giveit an almost fairy-tale appearance. According to theleader of the expedition, Max Wisshak, the water is actually crystalline and would be of rainorigin, which then infiltrated the overlying limestone. We still don't evenhave a clear idea of what biology might be. Now scientists are working to understand if those insidethere are microorganisms that can help us understand the origin of life onEarth. Q2 Doesa ceiling fan use more electricity than a light bulb? A2 Joseph Newcomer, Former ChiefSoftware Architect (1987–2010)11mo There isno such thing as “a” light bulb. Light bulbs haveratings, expressed in watts. For tungsten bulbs, this correlates with powerconsumption. For LED and other technologies, thenormalized rating is the number of lumens, or as it is often expressed,“watts-equivalent”, and does not correlate directly with the current consumed, which couldbe as low as 5% of the power required for a tungsten-filament bulb ofequivalent lumens. So unless you specify the technology of the light bulb andits power consumption you have no idea how to compare it to a fan.And there is no such thing as “a ceiling fan”. Thereis a specific fan model made by a specific company, and it may bevariable-speed and consume different amounts of power based on the selectedspeed. So unless you giveus the manufacturer, model, and datasheet for the fan, there is no way tocompare its power consumption to anything, let alone an unspecified light bulb. My note- Generally fans consume around 65 watts and a tube light of LED type 25watts. So fans consume more current. Q3 Whichis a better option, an inkjet printer or an ink tank printer? A3 Ashok Pandey, Manager at Cyber MediaIndia (company) (2014–present)1y The majordifference is the technology - Ink Tank printers work on tank technology and InkJet printers oncartridges. Where ink-tanks prove to be a better option ascompared to cartridge based printers are lower print cost, quick refilling, andhigher page yields per refill. Their quality of prints are also better.Regular inkjets have a low initial purchase cost, but their running cost ishigh. Theentry-level inkjets are therefore good for occasional printing needs.There are high-end inkjets also that offer high-quality color prints and areideal for home and work setup For high volume colour prints, ink tank basedprinters dramatically reduce your per-page printing cost. For instance, HP ink cartridge printers start at INR 2499while the smart tank ones start at INR 12,499. My note- So for offices ink tankprinters are preferred and for home needs inkjet printers. If my printing is 2-3 pages and emergent I use myprinter. Otherway, if printing is more I transfer the matter to pendrive andprint in shops. Q4 Whatare the benefits of visiting Niagara Falls from the US side? What are thebenefits of visiting Niagara Falls from the Canadian side? A4 Steven Haddock, 3rd generation (orso) Canadian & lifelong resident; political science major Mar 14 The U.S. side is significantly less touristy than theCanadian side. Historically, Niagara Falls, NY wasan industrial city, once the home of Nabisco Brands and Alcoa, which both took advantage of thecheap electricity. That being said, the main park on the falls is abeauty with three views of the edge of the falls, plus a footbridge thatcrosses the American Falls portion of the Niagara River. Goat Island, which lies between the falls, has also beendeveloped as a nice park. Now, that being said, one ofthe problems with the American side is there’s really nothing outside the park. There are are a few hotelsnear the American Falls, but very little in the way of shopping or eating.The city’s most important non-Falls tourist attraction, the Aquarium, is a longway from the park. Over on the Canadian side, the area around the falls isjam-packed with hotels, shopping and other attractions from the ridiculous (theRipley Museum) to the sublime (Bird Kingdom). Moreover, the view of the falls is better asit’s hard to see the entire American falls from the American side - the view from the Canadian sideallows you to see the whole thing from a distance. There are two majorobservation platforms on the Canadian side (Skylon and the Wheel) and none atthat height on the American side anywhere near the falls (there is the SenecaCasino). You will find morefood and accommodation options in Canada, and Canada runs a bus network betweenthe major attractions and the tourist areas. Q5 Whydidn't queens protest when the kings take many concubines during the medievalera? A5 Matt Riggsby, MA ArchaeologicalStudies, Boston University Sat Toquibble, “concubines” weren’t really a thing during the European Middle Ages.To most historians, that implies a somewhat formalized and more or less publicrelationship. We speak, rather,of mistresses, which was usually an informal, even covert relationship. Thatis, kings certainly didhave romantic and sexual relationships beyond the bounds of marriage,but they usually tended to limit themselves to just one or two siderelationships at a time rather than maintaining a large body of mistresses andto maintain a pretense of not doing so. (Mind you, this was sometimes an “opensecret,” where commenting publicly on the king’s extramarital affairs would getyou in trouble, but everybody knew it was happening.) Thatsaid, queens most certainly did protest. Thisis a Renaissance rather than Medieval example, but Catherine de Medici saidsome scathing stuff about her husband’s mistress (Diane de Poitiers, who had along-term relationship with her husband King Henry II of France), like “nowoman who ever loved her husband succeeded at loving his whore.” Other queenshad similarly contentious relationships with their husbands and their husbands’mistresses. But their protests were typically constrained.Forone thing, at that level, royalspouses were usually selected for political reasons rather than personalaffinity. That is, there was often little or no love lost between kingand queen. A queen might be upset about there being a rival for gifts and othermaterial benefits which might otherwise go to her, or that she might be seen asa laughing stock at court, but there’s an alienation of affection aspect whichjust isn’t there for many royal marriages. Infidelity has an entirely differentcharacter for people who are in what’s essentially a business relationship.Moreover, while a queen mightnot be happy about the infidelity, there’s not actually a lot she could doabout it. There weren’t really any higher authorities she could appealto, and nobody could tell the king what to do. Thechurch might disapprove on some level, but they were unlikely to upset thecomplicated framework of royal and ecclesiastical politics over what everybodysaw as a domestic matter. At best, a queencould (and did) complain to her friends, but not do anything of substance. Queens protested, but they did so privately, because that’sabout all they could do. Q6 Howdoes a fan reduce the temperature of a room? A6 William Kaukler, materials scientistfor decades 4y A fancannot reduce the temperature of a room. It consumes power, getswarm and raises the temperature of a room. The fan ONLY makes it feel cooler by moving the air whichacts like a breeze to take moisture off our skin and evaporatively cool theskin. You are making the room feel cooler with a fan. If the fan is aceiling fan, then its job is to move air AND prevent temperature gradients fromtop to bottom. Cold airsinks to your feet and hot air rises to the ceiling. You stand or sit on thefloor where it is cooler. Good in summer/bad in winter. A fan willmake the room more uniform in temperature which makes it feel more comfortablebut not lower the temperature. My note- The same with air conditioners also. Afterrunning for hours while the floor becomes some what wet, if one goes through stairs in a room, he can feel warm whilegoing up. Q7 Whatare live, neutral, and earth wires? How do they work? A7 Ian Plunkett, B Com in ElectricalEngineering & Automatic Control of Conveyor Belt Tension, St. George'sCollege, Harare (Graduated 1978)2y Your power connections require 2 conductors, Live (high)and Neutral (Low). Between the two conductors is avoltage of 110/120 VAC or 220/240 VAC This is what powers your appliance. The neutral is connected toearth back in the Sub-Station. This makes the other wire ‘Live” orHigh. If you come into contact with this ‘Live’ wire you can be electrocuted.The earth is there to give you a measure of protection. The earth in the Sub-Station has a very good connectionto ground and is usually supplied to you via a third conductor.You can of course provide your own Earth but this is not always easy if youdon’t have metal water pipes. if your appliance develops a short to its metal case, or if it get wet,and you don’t have an Earth Connection, you are likely to be shocked. Many modern appliances are ‘DoubleInsulated and do not require an earth although if the appliance gets wet youare still in danger. Mostdomestic electrical Systems have an Earthy Leakage Trip set at about 20 mA andthis is the most reliable method of protection. Q8 Sincebottled water is a relatively recent thing, did people 50 yrs ago drink a lotless water daily? A8 Michael Mombourquette, Chemistry Professor,Church member, Knight of Columbus, 5y If you’re comparingpeople from 50 years ago with today, I would say that yes, many of them drank less than peopledo today. However, that is not necessarily a bad thing. In the vastmajority of cases, people of 50 years ago got water from the tap or from adrinking fountain (I did) and never went thirsty. When I was a kid in school in the ‘’60s or auniversity student in the ‘70s, no one carried water around with them.No one felt they were always in need of a nearby drink. Perhaps a few of us didget a bit dehydrated from time to time and we felt really thirsty, after a longday of manual labor or sports or just being out in hot weather and we reallyenjoyed a big drink of water. Unfortunately, a small number of people of theday went a bit too long without water and suffered a bit or a lot, depending onthe extent of dehydration. I got dizzy and nearly fell off a roof I was workingon as a teenager on a hot July afternoon. My Mom saw me and called me down immediately.I was told to sit in the shade and drink a glass of ice tea. She has seen herown teen-aged brother years earlier fall off a roof unconscious from heatstroke and didn’t want it to happen again. Athletes of the day used to think it “manly” to lose 15lb of weight ona workout from sweating. After a few high-profile deaths fromheatstroke, that mentality faded and sports drinks like ‘gatorade’ (developedfor the University of Florida Gators originally) were developed to replenishthe water and electrolytes that were being sweated out. Today, we all fear dehydration so much that we cannotseem to stray very far away from our water. Studentswhere I work are often seen carrying around bottles of water and sipping fromthem regularly. Likely, the vast majority of us are simply drinking too muchand as a result, we have to go ‘make water’ in the urinals and toilets moreoften than we would normally need to. My note- During primary school days we studentsused to go to near by homes, where they fetched water from wells and kept inpot with tumbler for drinking by children. In mymiddle school, water was kept ready fetched from well in large copper vessel for drinking either in interval or noon intervalfor meals. In high school water was kept ready in pots in verandhaand in collegespecial dining room was there where water tap was provided with tumblers todrink water. This was from1949 to 1964. Q9 Whyis bread in supermarkets so sweet in America? A9 Matt Riggsby, MA Archaeology, BostonUniversity1h If you’re cominghere from another country and discovering our mass-produced bread is muchsweeter than what you’re used to, please understand that you’re coming into something which is the resultof a process which has been going on for decades. Once upon a time, our bread was like bread pretty mucheverywhere else, made from flour, water, yeast or a yeast culture, and salt. Modestquantities of sugar were added for specific purposes: to get the yeast toferment faster, to give the bread added softness, and, yes, to provide asweeter flavor. As we moved towardsmass production, all of those were significant. Faster rising means fasterproduction, we developed a cultural preference for softer breads, and we tendedto prefer things a little more rather than a little less sweet. That last onehas proved particularly problematic in the long run. We didn’t jump to using lots of sugar. Rather, it was incremental. People wouldbuy slightly sweeter bread, so manufacturers would add a little more sugar and theaverage sweetness increased. When people got used to that,someone would make their bread a little sweeter still, and so on until, by theprocess of may slow steps, we’ve gotten to where we are now, with supermarkets selling sweet,foamed, wheat-based products labeled bread. It is stillpossible to get bread with less or even no sugar. Many supermarkets have a section of fresh-baked andcloser-to-artisanal baked goods which typically includes more classical breads,and there are bakeries which provide the same, to say nothing ofwhat a minority of people still bake at hoe. But mainstream bread is the resultof a slow drift of preferences, getting a little away from what it was and alittle bit more like what it is over the course of generations. Q10 Howdo you know if water is boiling? A10 Chonghan Liu,3y Look for the bubbles collecting at the bottom of yourpot, when that happens, you’re close. wait until thebubbles get bigger and rise, and the steam gets more intense. Once there are so many bubblesyou can’t see clearly in the water, then it’s boiling. Boil the water in a potat max temperature.
