QUORA ANSWERS NEEDNOT BE 100% CORRECT ANSWERS. Compiled and posted by R.Gopala Krishnan, 80, on 13-11-2023. Q1 Doesiron block radiation? A1 SilkRoad,AI Expert6h The short answeris: yes, but not very well. The long answeris: it depends on what kind of radiation you're talking about, and how thickthe iron is. Iron is a metalthat has a high density, but not as high as lead or concrete. It can block some radiation,but not all of it. For instance, a thick piece of iron alone can nearly block all parts ofEMF radiation. We can magnetize the iron to make a magnet that blocksEMF radiation. However, even if we magnetized the iron, nothingabout the magnetization process would increase or decrease the iron’s abilityto block the EMF radiation. Steel is an ironalloy that can also block some radiation, but not very well. Steel’s ability to blocknon-ionizing EMF radiation lies in its conductivity. Some types of steel aremagnetic and some are not. When itcomes to blocking x-rays or gamma rays, iron is not very effective. It can reduce the energy of theserays, but not completely stop them. This is because these rays have high energy and can gothrough most materials except for very dense ones likelead or concrete. The effectiveness of shielding depends on stoppingpower, which varies both with the type and energy of radiation and theshielding material used. The process of radiation attenuation can be achieved byplacing an absorbent substance between the source emitting radiation and anindividual, workspace, or radiation-sensitive instrument. The radiation shielding calculations and propertiesof any material are presented in terms of the linear attenuation coefficient. So, if you want to block radiation with iron, youneed to use a lot of it. And I mean a lot. Like several inches or feet thick. And even then, youmight not be able to block all of it. You might bebetter off using leador concrete instead, because they have higher stopping powersthan iron. Q2 What aresome amazing facts about humans? A2 IanO'Grady, Studied TV and Film Production10h A female pregnant corpse will build up enough gas to expel the foetus even after death. They call it a “coffin birth.” You sneeze with enough force to kill you, but yourbody knows how to mitigate it. A dead body will often move as it’s being cremated. Muscles contract as they cook,and sometimes a body will sit up in the crematory chamber. The brain is pre-programmed on how to shut down inthe event of death. You probably have gotten cancer this week, but yourimmune system fixed it. The pain you feelfrom sunburn is your skin cells effectively killing themselves before theymutate into cancer. The brain eats itself when you don’t get sleep. If something was to pierce your body, if it’s therefor longer than 17 minutes your body will begin to push it out. At some point, our brains thought it necessary tofear some things that look close to humans, but aren’t. “The uncanny valley.” Q3 Whatmakes the German chocolate that Aldi sells so amazingly good? A3 VolkerEichener, Professor at Hochschule Düsseldorf18h Germany is by farthe largest manufacturer and exporter of chocolate. In terms of value, Germanyexports over than six times more than Switzerland. In fact, many Swiss brands (e.g. Lindt) are produced in Germany, mainly in Aachen. There are many German chocolate brands in German withhigh quality, including some low-cost brands. There is an axisof three countries which produce superb chocolate: Switzerland, Germany andBelgium. Thesecrets behind their quality are quite simple: Long-timeconching, for 24 hours. This gives the chocolate a smooth texture. Chocolate (like Hershey’s andmany French chocolates with a sandy texture are not conched long enough. It isas simple as that. ingredients. Dark chocolate has nothing butcocoa butter and sugar. Lighter chocolate has milk powder added. You may also add flavourings like nuts, nut paste, driedfruits, gianduja - whatever. However, if you replace cocao butter with inferiorfat, like palm oil, the taste is watered down. After all, it is not so difficult to make good chocolate. The mainthing is not to be too penny-pinching. American business mentality maybe the problem: cut the costs at all price!!! The result is poor quality likeHershey’s. When you are in Germany, you may have a look into thechocolate museum in Cologne: If you are in Berlin, pay a visit to Rausch on theGendarmenmarkt, Berlin’s most beautiful square. They sell their own chocolate, they displaysculpures made of chocolate and they have an upstairs restaurant serving saltydishes which a are made with chocolate. Very tasty! My first recommendation for lunch in Berlin. Q4 What aresome of the most mind-blowing facts? A4 Gamers,54m Right up until1952, Olympic medals were handed out for sculptures, paintings, music, literatureand other forms of art! The amount of Nutella manufactured every year isenough to complete 1.8 round trips of the earth!This is one of those amazingfacts for kids that will blow your mind! Did you know theorigin of French can be traced back to Belgium? They are not French! Can you guess the number of seconds in a year? It is31,536,000 seconds! Did you know what the fear of numbers is called? Arithmophobia. Now itmakes sense why they call it arithmetics! If you add up each of the opposite sides of a dice, thesum total will come up to 7. Known as the Pinnochio effect, your nose actuallyturns a bit warm every time you tell a lie. Q5 Why wasHitler's decision not to attack Moscow the right decision? A5 StartSameer,Business Anaysis at Max Life Insurance (2020–present)19h Hitler once saidthat his generals understand war but not economics, and this was one of his cleverstatements. The generals of Nazi Germany were smart andexperienced in warfare. They knew how to use and destroy armies well. However,what they didn't get was the bigger picture. So, why wastaking Moscow not the right decision? Firstly, it'sdebatable if the Nazis could even take Moscow. They had already failed to capture Stalingrad andLeningrad, so why would Moscow be different? Taking Moscowwouldn't change much. It's a challenging city to capture and wouldn't give the Germans manyadvantages. The USSR wasprepared to lose Moscow. They expected the German attack and were ready to keep fighting withoutlosing momentum. Napoleontook Moscow, but did he win? The valuable regions for Germany were in the Urals,where important resources and equipment were being produced. Germany's mainfocus was in the South, and that was the right priority. When Germany invaded the USSR in 1941, their goal wasto defeat the Red Army and force the USSR to surrender. However, as they faceda resilient Soviet Army, their strategy shifted. Realizing thatdefeating the entire Red Army would take more time, Hitler changed the focus. Instead of trying to defeatthe USSR outright, Germanyaimed to capture the oil-rich Caucasus to solve their fuel shortage. If they could capture the Caucasus (which wasunlikely), it would be a significant victory, providing them with enough oil tosustain their war effort and depriving the USSR of a crucial fuel source. In contrast,capturing Moscow would just mean occupying another city without gaining newresources or winning the war. The strategic situation would remain mostly unchanged.While Moscow was a rail hub, other major cities the Germans had captured alsoserved that purpose, and it hadn't won them the war yet. Q6 DidEinstein struggle with any math? A6 DevvratHans,Sep 2 Yes, Albert Einstein, despite his remarkable contributions totheoretical physics and his development of the theory of relativity, did face challenges in certain areas of mathematics. It's important to remember that Einstein wasprimarily a theoretical physicist, and his strength lay in his ability to formulate andunderstand complex physical theories rather than in performing intricatemathematical calculations. Here are a few aspects of mathematics in which heencountered difficulties: Tensor Calculus:Einstein's theory of general relativity relies heavily on tensor calculus, a branch ofmathematics that deals with tensors, which are mathematical objects used todescribe the curvature of spacetime. While he had a deep conceptualunderstanding of the mathematics involved, Einstein struggled with themathematical intricacies of tensor calculus. He relied on the assistance ofmathematicians, particularly Marcel Grossmann, to develop the necessarymathematical tools for his theory. QuantumMechanics: Einstein made significant contributions to the development of quantum mechanics,but he was famously uncomfortable with some of its probabilistic andindeterministic aspects. He often expressed skepticism about the probabilisticinterpretation of quantum mechanics, famously saying, "God does not play dice with theuniverse." This philosophical disagreement with certain aspects of quantummechanics led to debates with other prominent physicists of his time, includingNiels Bohr. Unified FieldTheory: Towards the latter part of his career, Einstein attempted to develop a unified fieldtheory that would unifythe forces of gravity and electromagnetism. While he made some progressin this direction, he was unable to formulate a complete and successful theory.The mathematical complexity of such an endeavor posed significant challenges,and Einstein did not achievehis goal of a unified theory during his lifetime. Despite thesechallenges, Einstein's ground breaking insights and contributions totheoretical physics revolutionized our understanding of the universe and had aprofound impact on the field. His ability tothink deeply and conceptually about physical phenomena allowed him to transcendmany of the mathematical difficulties he encountered. Einstein's workcontinues to be a cornerstone of modern physics, and his struggles with certainaspects of mathematics serve as a testament to the collaborative nature ofscientific progress, Q7 What arethe most middle class things ever? A7 GurmeetBishnoi, Lives in Berlin (2023–present)1y Rahul wasenjoying dinner with his family. Family gossips were going on. Everyone got excited whenRahul’s dad said this- Dad: I wanted togive a good news to all of you? Rahul: Yes, go ahead. Dad: We are buyinga car this Monday.I have been to agency today and selected the car. Sister: Wow! Which car dad? Dad: The samewhich your uncle has bought recently. He told this is good car and in our budget. I have some saving and rest willbe finance. Everyone was happy and excited until Rahul put aquestion, Rahul: But dad, we do not need a car. If we needoccasionally, we can ask from uncle for his car. Why we should get financialburden now? Dad: I do not want to beg car from someone. We canalso by ours, we are no less than him. Rahul did not say anything and started focusing ondinner while everyone else was discussing about new car. He said to his mom, Rahul: Mom, give me a tomato as a salad. Mom: Are you crazy? You know tomato prices are touching sky. We are buying acar, we need to save money. Rahul did not say anything. He finished his dinnerand went to bed. Next morning when he went to bathroom, he shouted- Rahul: Mom! Mom! Mom: What happened? Why are you shouting? Rahul: It hasbeen three days I am telling you that toothpaste is finished. Why do not you ask dad tobuy new ones? Mom: There isstill some toothpaste inside this. Use some power and press it, paste will come out. Now Rahul got to understand that he have tocompromise with lot of things because they have bought a car. Most middleclass things: Competition with neighbors,buying car but do not buytomato, compromising with daily life needs, food, save money for years likethis and then spend all in daughter’s marriage to makesociety happy .where different individuals with diverse skills and expertise work together toadvance our understanding of the natural world. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
