CULTURAL QA 10-2022-16 BEING A COMPILATIONTHERE MAY BE ERRORS
Q1 How did humans evolve to be the onlyspecies on Earth capable of using tools? A1 Claire Jordan, Degree in biology andfolklore; programmer, shop owner, secretary on newspaper Fri We aren’t. We make the best tools, yes,but many other species use found objects as basic tools, and some actually makethem. Some crows, for example, will bend a twig into a hook toget hold of something, and chimps will peel a long stick and use it to catchtermites, and there are many other examples. Humans make thebest tools because we adapted to be very bipedal in order to see over the longgrass on the plains, and to do endurance running. That freed up our hands so they didn’t have todouble as walking feet. From there, our hands evolved to be moredexterous and our brains evolved to be bigger, in tandem, because making bettertools enabled us to feed and protect ourselves better and have more kids. Q2 Is nephrology a good career choice inIndia? A2 Medvarsity Online, Asia's LargestEdTech Healthcare Company Thu Did youknow? There are only 2,600 certified nephrologists that are practicing inIndia, where the population stands nearly at 1.3 Billion! According toresearch and industry trends, the Indian nephrologist market is forecast toreach 102.7 million by 2027. Diabetes andhypertension play a crucial role in chronic kidney disease. As a result, thedemand for certified nephrologists who can provide optimum care forkidney-related concerns is expected to rise. Individuals who take a fellowshipcourse in Nephrology will be able to specialize in this niche specialty inorder to benefit the general public. In addition togaining clinical experience through contact programs at reputable hospitals andclinics, aspiring nephrologists can also explore evidence-basedclinical approaches and novel treatment guidelines in kidney care by enrollingin fellowships in Nephrology[1] Medicalprofessionals looking to build a career in the industry can find nephrology tobe a lucrative career choice. Footnotes[1]Fellowship in Nephrology - MedvarsityOnline Course Q3 How can the service of Indian Railwayspractically be improved? A3 Balaji Viswanathan, follows governmentpolicies closely. Updated 7y Here are some of my random thoughts on this: Hotels built above station platforms: Railwaysstations are right in the middle of the cities and they don't utilize theprecious space above the platforms. Here is acres and acres of red-hot realestate space right in the middle of New Delhi. Why not build hotels right ontop of this space (with sound proofing, of course)? Travellers could stay in safe, convenient centrallocations, while railways could make huge revenues. Multi-Modal Transit options: A key to a goodtransportation system is the ability to switch between multiple transportationoptions easily. A guy landing at Delhi airport should be able to take a directtrain to Meerut or Haridwar or Jaipur or Simla right below the airport. Thetransfers should be seamless between train & air and train & buses. Information outlets: As you land in a randomstation, you should be able to go to an "information booth" that justbeams you local information as a file to your phone (through bluetooth/wifi).Or you can interact with the touch screen. It should contain all major touristplaces and authorized hotels/travel guides/taxis as curated by the localstation master. You don't want to miss out the important stuff when you aretraveling. Cover the tracks with solar: Railway tracks aregreat pieces of real estate over which solar panels could be installed. The power could be consumed rightunder the panel by the electric trains. No need to store/transfer power toolong. Fast conversion to sitting trains: One of the biggestproblems with IR is the very low capacity. Because a lot of the trains areslow-sleeper trains. The Kaveri "express" - a sleeper train betweenChennai and Bangalore (actually it goes up to Mysore) takes 5 hours for littlemore than 350km. This is a premier express between two major metropolises. Thespeeds are pitiably slower in other routes. However, our tracks can carry trains with 200 kmph (thepeak speeds of Duronto). What if we could replace all Chennai - Bangalore/Mysoretrains as high speed trains taking sitting passengers in 2-3 hours.Sitter compartments can take twice more passengers than sleepers and by alsodoubling the speed, we can achieve 4x capacity without extra investment in thetrack. The same for all routes under 1000 km. Those could be covered by highspeed sitting trains, dramatically increasing capacity across the system. Wifi connectivity on all trains: Rajdhani already hasWifi. It should be extended to all trains. Let the nation be more productive byletting knowledge workers working right on the train, during long travel times. Upgrade the sanitary experience: The slow movingtrains are a disaster in cleanliness. As the trains go longer, the stink goeshigher. As you rapidly shorten the travel times, sanitary experience will bebetter. But, more importantly, new tech should be used for creating highlyhygienic toilets. My note- Mostimportant except the first one is removing deficiencies in the reservationsystem. It should be more simple than today’s and quick. Allocating 30%berths under thatkal is aiming at high revenue. Further the systemof thatkal rate change under dynamicsystem isleast appreciated. Further more deficiencies like allotting upperberth for very senior citizen is a clear deficiency of software. Suchthings are to be removed. Either in counter or on line, making only upper berthavailable near the departure days is ridiculus. Many passengerexpress trains providing may change the condition. Q4 What makes stallions harder to trainthan other horses? A4 Pat Brown, Studied equine behavior,biology and history Oct 1 Because astallion is a walking, prancing pile of hormones. All their attention is oncollecting mares for their band. And fighting off any rivalstallions who want to usurp their harem. A wild horse herd consists of a mature stallion, hismares and young foals, including colts who stay until they are about 2–3 yearsold and break away to form bachelor bands. Most people think the stallion protects the herd but allhe really does is protect his claim to the mares from other stallions.The true leader of the herd is the lead mare. She decides where they go, shedecides when they stop to graze. She also keeps discipline in the herd. Being so singleminded it takes a firm, but not violent, hand to train a stallion. Consistency,not letting the stallion get away with bad behavior and continuous training forreinforcement. I’ve been around some very well mannered stallions, oneso mellow children could ride him. But I wouldn’thave trusted any of them if a mare in heat crossed their path. Then they gofrom this: Q5 If eating white rice daily isunhealthy, how come our Indian ancestors are so healthy though they used tohave it daily 3 times? A5 Jyothi Siripurapu, I have a YouTubechannel on health and nutrition. Updated Thu Rice is simplecarbs which means that, after eating it is broken down quickly by the body tobe used as energy. If that energy is not going to be used, then it becomesunhealthy. I belong to Generation X. I have seen my grandparentseating white rice and still be healthy because, they used that quick energy todo the following day-to-day activities. Hand washclothes Carry water Use stone grinder for grinding Heat water in boiler Cook food on mud stove Hand pound grains Workin fields Milk by hand There was no sedentary lifestyle as there was lot ofphysical activity. They used to get tired and sleepby sunset. There was no stress as all were into farming, no technology (noserials to watch, no posting pics on social media, no YouTube, no Insta, noGoogle, no Quora, no checking WhatsApp messages etc.) Just eat > do hard physical work > sleep > andrepeat. When we eat white rice and do what they did,then we will be healthy too. My answer on ricethat is related - Jyothi Siripurapu's answer to Is it bad to eat rice everyday? My note- When any civilization developed, changes occurred,physical activity get reduced. It continues. I cannot agree that reduction ofphysical activity alone is the reason. Hard work getting away every day with new inventions even for cutting of trees, ploughing oragricultural methods. Q6 Since water is recycled naturally onthe Earth, how does water get high up to fall down, on waterfalls, and then getback high up again in the next turn like with Niagara Falls in New York? Surelyrain alone can't supply all that wide rushing water. A6 Steven Haddock, Studied at YorkUniversity (Canada)Oct 9 Niagara Fallis a “pinch point”, which explains why it’s so powerful Every drop of rainand flake of snow that falls in the light blue, light brown, yellow and pinkareas of the map, as well as in the upper four lakes (Superior, Michigan, Huronand Erie. Has no other way of getting out of that area other than passing overNiagara Falls. It’s no moreunusual than putting your thumb over a hose with low water pressure to greatlyincrease its range. And speaking of snow,a lot of it falls from November to March, then it all melts from March to May.This turns quiet little creeks into raging torrents. Lake Erie isessentially a massive reservoir for the falls, ensuring that it will alwayshave plenty of water available. In a simple analysis, the only way for water toget out of Lake Erie other than evaporation is over the falls. Q7 Is it possible to get shocked fromdrinking water? A7 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now My answer is yes under the following condition:- A voltage/ currentis applied on the line and touching water. Water is a conductor. Human body isa conductor. So the voltage/current will be going through the human body. Butif the human body is insulated he would not get shock. If thevoltage/current applied is low, and it is kilometers away in water (just like astream or river), water creates resistance and shock will not be felt. Think of a electricsingle phase line has fallen on a river by breaking. Near by water will createshock to a person getting down with barefoot can get a shock. River water isdrinking water. If you are asking by drinking water from a cup ofwater if one will get electric shock- answer is NO. Q8 Is it true that McDonald’s throws tonsof perfectly edible food away even though there are desperately hungry homelesspeople who would genuinely appreciate being given it? A8 Andy Christian, Oct 8 Sure. The problem is, if you give out food, you are open toa lawsuit. Let’s say I work atJim’s Burger Shack. I’m manager. I have a bunch ofburgers that are too old to sell, and I have to toss them in the trash. Instead I had outthe food to a homeless guy, or a bunch of homeless people. Here’s what can….and absolutely does, happen. One ofthose guys, being a homeless person, eats the food in an unsanitary place. Theyget food poisoning. They go to ahospital, they determine the food came from Jim’s Burger Shack, and then alawyer shows up investigating the incident, finds out it was old food I wasgoing to throw away. Now we endup in court, and the homeless guy gets a million dollars in damages from a badburger, that was likely contaminated in his trash pile where he lives on thestreet. Even if we win thelawsuit, the whole thing will end up in the media, and everyone will accuse usof giving old poison burgers to homeless people. And lastly, even ifnone of that happens, what happens when all the homeless find out they can getfree food from Jim’s Burger Shack? They start camping aroundthe store, and all the customers leave, and we go out of business. There is zero upside to this. And a hundred different ways it can blow up in our face. I’ll say the same thing I’ve said numerous times. If youthink that’s how a business should be run, I would encourage you to start yourown burger joint, and give out free food to thehomeless. See how that goes for you. Q9 What are the most mind-blowing factsabout the human brain? A9 Shivansh, Trying to write something Fri 1. About 75 percent of the brain is made up of water.This means that dehydration, 2. Can havenegative effects on brain function, even in small amounts. 3. The human brain will grow to three times its size inthe first year of life. It continues to grow until you are about 18 years old. 4. Headaches arecaused by a chemical reaction in your brain combined with the muscles andnerves in your neck and head. 5. Your brain uses 20 percent of the oxygen and blood in your body. 6. Alcohol affects your brain in ways that includeblurred vision, slurred speech, an unsteady walk, and more.These usually disappear when you calm down again. However, if you drinkfrequently over a long period of time, there is evidence that alcoholcan permanently affect your brain and once again not sober up. Long-termeffects include memory problems and some reduced cognitive function. 7. If the braindoes not get oxygen for 5-6 minutes, then it stops working forever. 8. As we growolder, the human brain becomes smaller. This usually occurs sometime aftermiddle age. 9. The human brainstarts to lose some cognitive skills by your late 20s, along with your memoryabilities. 10. A brainfreeze is actually a sphenopalatine ganglioneuralgia. It happens when you eator drink something that is cold. This stretches blood vessels and arteries to thevery back of the throat, including blood to your brain. These compress whenthey are cold and heat up again, causing pain in your forehead. 11. Dreams arethought to be a combination of imagery, phycological factors and neurologicalfactors. They prove that your brain is working even when you aresleeping. 12. It is amyth that humans only use 10 percent of our brain. We actually use it. We usemore than 10 percent when we sleep. 13. During human evolution, the brain has tripled insize. 14. Your brain usesthe same amount of power as a 15 watt light bulb. Q10 Do oranges get geneticallymodified and this is why they have such a thick skin? I ate one that lookedlike half after peeling. A10 Joshua Engel, Enthusiastic eater andadventurous cookThu Oranges were bred — hundreds of years before geneticmodification — to have thinner skins than their wild ancestors. The original citrus species have been lost, but they maywell have looked more like this citron: Or this pomelo:Thatpith layer protects the seeds — possibly even as they are eaten by animals sothat they can be distributed far. Nature didn’t evolve it to make it easy foryou. There aren’t any genetically modified fruit trees. Westill produce new fruit versions by letting nature introduce new varieties andselecting the ones we like, just as we have for thousands of years.Citruses were selected for thinner, not thicker, rinds, because they’re easierto eat and more desirable to consumers My note- I think we produce new varieties by pasting togetherwhen the plant is young afterremoving skin for certain area and binding together. Especially in oranges weget different varieties like this. All the above QA are from Quora website on 15-10-2022 Quora answers need not be 100% correct answers . Compiled and posted by R.
