They were already stripped from so many quarters, standing naked; shame is only to those who think high. But how an ignorant RUTs like these, would relish the righteous thing. Their goal is trying hard to hit the good so that they think, all are thinking, everyone believes their words; but the reality is, they are being laughed at . People who have content will retort by content. But ignorant fools will only jibe at a packet pocket etc as if the whole content lost the value or in their minds, all think, the content is wrong. They live in fools 'paradise. Sheep and Goats lie only like Gopalkrishnan and Narayana samy. Welcome both of you. Have you read Periyava words?How will you admit ? Your interest is sel shaming, thinkin withimagination, others are doing so. Poor sheep Let them bark loud. I am waiting Both of you cannot even touch my toes. Bye unashamed. KR

The correct wording as per Mr Rajaram's dictionary is milk pockets for the milk packed in a pouches.

KR As admitted by G and repeated once again, apple fall alone s true; but as you don’t know whether Big bang happened only this way, so too, Newton did not write any script, whether fell on his head or not, or only one apple fell or so many apples. Myth is purely your imagination. And as one Quora can spin yarn that Gandhari opened her eyes and someone bluffed “I also Heard Duryodhana etc”, so also in Quora there are so many bluffers and willing to consume members. #2The higher you are (building-wise), the faster time will go. Time is a hard concept to understand when you look at it through the lens of physics. A couple of seconds while standing on the ground will go slower than for someone who sits on a high building, like the Empire State building. It is best explained by Einstein and his famous theory of relativity. KR: I think he is repeating the old set in the same order and already I had written how time is different within and beyond the Newton and Einstein gravitation. So, this fact is false as usual. For every degree of longitude covered from east to west, time changes by about 4 minutes. This is because the Earth completes one full rotation every 24 hours, which means it rotates 360 degrees in that time. Therefore, the Earth rotates at a rate of 15 degrees per hour, or 1 degree every 4 minutes. How far is 4 degrees of latitude? The Distance Between Degrees of Latitude and Longitude; Each degree of latitude is approximately 69 miles (111 kilometres) apart. At the equator, the distance is 68.703 miles (110.567 kilometres). At the Tropic of Cancer and Tropic of Capricorn (23.5 degrees north and south), the distance is 68.94 miles (110.948 kilometres). IF SO, HOW THE TIME WITHIN 70 MILES TIME WILL VARY, WHERE EVEN LIC’S ONLY FEET HEIGHT INFINITESIMAL. THE BLUFFS ARE APPRECIATED ONLY BY SUCH COMPANION EXTOLLING WITH LOTS OF ADJECTIVES!! #3 The screens of smartphones work thanks to the electric charges leaving our fingers. Touch phones work thanks to the physics behind the human body itself. When we touch the screens with our fingers, we let out a small number of electric charges that register with the mechanics and allow us to interact. For this reason, things like rubber, fingernails, and others don’t register KR *Even with rubber gloves the screen will work sir* #4 It’s nearly impossible to sink in the Dead Sea. The Dead Sea is popular for the number of tourists that visit it, but also for having a large amount of salt in it. Salt is not only good for food, but also a good way of making the water much denser. There is so much of it in that sea that people who swim there have little to no chance of drowning. Of course, it is still important to keep things safe. KR Why named dead sea? The Mystery of the Dead Sea: How your organization can reconcile its core business with memory and innovation Let’s open the door to another mystery... This time on the other side of the door, this was not a room but a terrace opened to a gigantic sort of lake, an unknown smell filled the air and as I looked around to ask for direction, I saw a strong man carrying some sort of buckets walking towards me. His buckets were full of salt. He explained that the Dead Sea is Earth’s lowest-lying "land" spot with shores at 1,400 feet below ocean level, and very salty waters down 1,200 feet with deep deposits of salts and sediments of the Jordan River drainage. He looked exhausted but his knowledge was impressive. A true expert in the subject matter he went on explained that the Dead Sea has been shrinking rapidly because of evaporation and water being pulled from the river. He illustrated how climate change was drying the region putting more pressure on the water supply: this sea had no fish, no plants, no boats and the salt prevents life from thriving. I asked him if there was anybody else there, he said no. No alt text provided for this image Later on I met an old lady, she also thought she was the only one there, she had never met that man, but interestingly enough she was carrying the same bucket, expect this time it was filled with mud. She went on and on about how this mud was precious, how it can reduce skin impurities and cure some diseases, how it provides relief for arthritis and it helps soothe chronic back pain. She said that the mud holds the secrets and memories of the region and all its living creatures, event and seasons. I though that she never met the man probably because he was always there during the day and she was only there in the evening. No alt text provided for this image Eventually I met a young woman full of energy and this time carrying a bucket of fresh water. She told me that one can obverse and learn a lot about the dead sea, by paying close attention to its seasonality. All the salts on the bottom of the Dead Sea during annual dry seasons contain uranium isotopes she said, which makes it possible to date sediment layers season by season. Some of the mud deposits washes down from the hills in the wet seasons. She had a very thorough methodology to observe that when there is prolonged drought, thicker layers of gypsum and salt deposits appear. From these deposits, researchers can find evidence of water chemical components, but also winds and climate change clues, some of which indicate that it is not the first time that the dead sea was disappearing (click here to know more from Columbia Earth Institute). No alt text provided for this image I tried to test a little experiment and have these three fictional characters meet. They were living their lives in different times, in silos, without knowing that they can learn from each other. When the young lady met the old one she used the fresh water to clean the sediments and fossils that testified of the ancient story of the sea, they talked and learned among other things that rinsing the mud with fresh water makes the skin even more glowing. When the man joined them he took a moment to look at his reflection in the fresh water bucket and saw how tired he looked. This moment of reflection made him realize that he should direct his efforts more strategically to save energy and time. The old lady applied some mud on his back to relief and soothe his chronic pain with ancestral knowledge. In the meantime, the young lady was listing all the solutions that can be built using the salt he had collected: salt helps remove watermarks from a wooden surface, polish copper tools, remove bad smells, avoid insects and so much more she said. For in every problem in our eyes someone else in a different time can see a solution and teach us to be stronger, wiser and more strategic. ------------------------------------------------------------------------- #5 Wind casts an invisible shadow. Shadows are not always cast by objects, and winds can do it too. The only problem? We can’t see them with the naked eye. Wind, a movement of a gas that varies from a small gust to full-on thunderstorms, can cast a small shadow only visible with the help of machines and physics. KR Repeat Already replied Wind can never cast any shadow; Where it is unseen it is not called a shadow. Any facts stated anywhere, shall be fully read and understood; or else better not to venture, because 2 people only encourage him. Any matter blocking the light only resulted in a dark shadow and hence only any blocked energy area is called SHADOW REGIONS. Air is transparent and so light can pass through. Unless there are dust in air, shadow can never form at all. Exception is like this: “Uniform air itself cannot refract light and create shadows because the index of refraction does not differ anywhere. But, *when different regions of air have different indices of refraction*, the air can indeed bend light away from the forward direction and create a shadow. Under conditional state alone and not all. #6 Light gets much slower in water. Water is not only a refresher at the end of the day, but also a great stopper for the wavelengths of light. Light travels through air at a very high speed, and that is thanks to its small density. Water, however, is thicker. Since every molecule has surface tension, light gets distorted due to the amount of energy needed to pass through. My note- Refraction studied and performed experiment about refractive index of materials in Physics class KR You mean school pencil experiment? Again wrong. Light speed is constant; but where the transparency is opaque, the light in a group wrt that opaque medium, only travels through all the median particles by absorption and not reflection, which is refractive; and if normality is one, refractive index is 1 Plus; so as RI increase ,viz opaque medium is thick, the time THAT GROUP LIGHT ALONE TAKES ALONG TIME TO PASS OF THE STRAIGHT LINE, IF IT WERE TRANSPARENT; SO SPED IS PRESUMED TO DECREASE WRT THE TIME IT TOOK TO REACH TRANSPARENCY AGAIN AND THAT TOO WRT THAT GROUP OF RAYS ONLY. In glass it is still slower than water. It is a mirage. Has any one asked while reflections are taking place, do light travels faster viz “C” is accelerated? Science gives such twists. We say mano vegam; thoughts are faster than light; but science says NO; and confirms that the speed of information travels only slower than light. Yes, maybe emails; but what about myself thinking now that I am writing this from Milan? #7 Galileo Galilei proved his theory of free fall with the help of the leaning tower of Pisa. While Galileo Galilei might have created the theory of free fall, he had to prove it by experimenting. He did it by throwing two cannonballs of the same material, but different masses, from the leaning tower of Pisa. His theory would be further supported by missions to the moon. KR Mr Gopalkrishnan company of three gets wild where I prove his errors going unchecked, simply reproducing away, ascribing himself as a Physics student; however, till this day he cannot think rebutting anyone of them with staunch evidence either Vedic or Science as HIS co students also remain THUS. There are so many unchecked facts floating on the web sites, which the young and the old minds think as genuine and produce as awesome. But they are untrue, even when I was watching Periyava episode I Sankara TV, as great as Chanakya also made that error. There is an incident of Tirunallar Saniswaran; he said as from NASA saying that the satellites went slow when it crossed Thirunallar, because it is in the web. NASA denied so many things and this one also was denied. Galileo < Newton Einstein are all bluffs afloat and the main culprits are our own people, who gloat over, falsely about Vedas. “ At the time when Viviani asserts that the experiment took place, Galileo had not yet formulated the final version of his law of falling bodies. He had, however, formulated an earlier version which predicted that bodies of the same material falling through the same medium would fall at the same speed.[3]: 20 This was contrary to what Aristotle had taught: that heavy objects fall faster than the lighter ones, and in direct proportion to their weight.[3]: 9 [12] While this story has been retold in popular accounts, there is no account by Galileo himself of such an experiment, and many historians believe that it was a thought experiment.[13] An exception is Stillman Drake, who argues that it took place, more or less as Viviani described it, as a demonstration for students.[3]: 19–21, 414–416 Galileo's thought experiment concerned the outcome (c) of attaching a small stone (a) to a larger one (b) Galileo set out his ideas about falling people, and about projectiles in general, in his book Two New Sciences (1638). The two sciences were the science of motion, which became the foundation-stone of physics, and the science of materials and construction, an important contribution to engineering. Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion.[14] He writes: Salviati. If we take two bodies whose natural speeds are different, it is clear that on uniting the two, the more rapid one will be partly retarded by the slower, and the slower will be somewhat hastened by the swifter. Do you not agree with me in this opinion? Simplicio. You are unquestionably right. Salviati. But if this is true, and if a large stone moves with a speed of, say, eight while a smaller moves with a speed of four, then when they are united, the system will move with a speed less than eight; but the two stones when tied together make a stone larger than that which before moved with a speed of eight. Hence the heavier body moves with less speed than the lighter; an effect which is contrary to your supposition. Thus you see how, from your assumption that the heavier body moves more rapidly than the lighter one, I infer that the heavier body moves more slowly.[15] His argument is that if we assume heavier objects do indeed fall faster than lighter ones (and conversely, lighter objects fall slower), the string will soon pull taut as the lighter object retards the fall of the heavier object. But the system considered as a whole is heavier than the heavy object alone, and therefore should fall faster. This contradiction leads one to conclude the assumption is false.” For free fall, why PISA tower? even LIC will do or a hill. And again, it is conditional; only if there are no other forces reacting against it like AIR RESISTANCE ETC. And again, ARISTOTLE WAS ALSO NOT WRONG. Galileo is wrt Newton whereas Aristotle is Einstein's application universal; as refraction of light explained above. So its false and if I s0ay it is bluff he gets wild and says I abused him, unaware of his lack of attention. --------------------------------------------------------------------------- #8 The universe is growing every second. The universe is already a vast space full of planets, stars, and other celestial bodies. But it is still not big enough. The universe is growing at a high rate every second, expanding in every direction, getting colder and faster at the same time. This expansion has been going on for billions of years. KR I think Mr G forgot he already rolled over all these and his memory lapses induce him to get into anger. Where is the proof of expansion? Mass weight increased? Or distanced? If I shift nearer to farther Have, I expand or it is change of directions only. All states of matter can expand meaning changing shapes, areas, place of origin to elsewhere etc and as long the matter weight is constant, where is the real expansions? Battle of the bulge is one shrinking and the excess attached to the bulge. Discovery means, we are finding or learning very late, what is already in manifestations. The age of a person is time lapsed; but the science thinks the movements farther await which is a mirage. Because when I open the door of my residence and find the milk pockets, it does not conclude that the milk carrier was then only placed in all of them. ----------------------------------------------------------------------------------------------------- #9 Water can boil and freeze at the same time. At the same temperature, water can either boil or freeze. A triple point is a point where the temperature, pressure, and pressure value all coincide. The fact that all three states—liquid, ice, and water vapor—are present at this time allows water to boil and freeze at the same temperature. KR States of matter is conditional and if you allege that at one temp of zero or minus or plus, three states can co-exist , you have to prove it since what was stated then is HYPOTHETICAL in the sense , if these conditions do happen then…….. What is it called when water freezes and boils? It's a phenomenon called triple point, which occurs when the pressure and temperature are perfectly set for the three states of a substance—solid, liquid and vapour—to coexist in equilibrium. Water reaches its triple point a hair about freezing (0.01 C) and at a pressure of 0.006 atm (atmospheric pressure). WHEN WILL IT HAPPEN? ------------------------------------------------------------------------------------------- Q3 If an elephant’s brain is bigger than ours, why are they not smarter? KR Hope If I say today's kids knew it but not G and Co? Is there a status as “Brainless wisdom"? It is known as “anencephalic anencephalous foolish imbecile senseless silly stupid thoughtless witless. ROBOT is brainless but can do wonders than all the writers put together here. OWLS, CHIMPS, AND ORANGUTANS ARE MORE INTELLIGENT THAN HUMAN. The human brain is bigger than owl size. And do hope in future a similar question is not shot, titling every animal. Q4 Why was the old calendar changed? KR We all read and I had also written the time and calendar concept under our scriptures; but even the brain is bigger, without reading anything, as a JUNOON spectrum, one goes after the urchins to unfold the west side story only. Then all the words of the size of the brain answer shall fit tight. Q5 What is the craziest domesticated animal to ever exist? KR Bizarre is unusual; don’t we have such among our population. Do we call them crazy? Nature has created varieties which help the earth except humans. Pigeons are a friend of humans and never are they domesticated by us nor developed as pets. All animals including the Pythons are friendly with us. As long as they do not have a fear, we can be friendly even with a lion which many foreign women have done with. Pigeons were used by Damayabthi and heroines of kalidasa , sanga kappiya heroines and Kings as they are trained to fly through certain roots. Today even a couple of years back my balcony in T Nagar had quite a lot of pigeons; and suddenly they are nowhere now. I did Pigeon net to avoid them entering the rooms. But today the nets are alive but no pigeons. Where are they like sparrows? Mr Sekar wants comments from men of steel and not straw; well on time and various calendars I had written long as from Sanskrit and Tamil and even other regional versions. Good habits are in Grhya sutras written by so many. குறள் 490: கொக்கொக்க கூம்பும் பருவத்து மற்றதன் குத்தொக்க சீர்த்த இடத்து. பொறுத்திருக்கும் காலத்தில் கொக்குப் போல் அமைதியாக இருக்க வேண்டும், காலம் வாய்த்த போது அதன் குத்து போல் தவறாமல் செய்து முடிக்க வேண்டும்.

So we may consider English New year with equal importance to regional new year avoiding* *Meaning less things like lighting lamp at midnight in pooja roometc.* *Q3 If an elephant’s brain is bigger than ours, why are they not smarter?* *A3 Gary Meaney, author of Zoology's Greatest Mystery (2022)Nov 2* *This is a good question, because the answer teaches us a lot about the nature of intelligence itself* *The average human brain weighs about a kilogram and a half, which is remarkably small really**. The sum of all consciousness is housed within that little scoop of nervous tissue. On the other hand, within the cranium of an African bush elephant sits a brain well over twice the size of ours.* *It’s clear that there’s more to intelligence than just brain size. The baleen whales of the oceans have brains weighing 7 kilograms, well over quadruple the mass of ours. However, their behaviour is much less complex and sophisticated than that of humans, or indeed of elephants. Baleen whales aren’t stupid - their songs are a rich and advanced form of communication, and they’ve been known to display altruism - but their intelligence definitely isn’t proportional to their massive brain size.* *This is of course because their brains are tiny relative to their bodies**. A blue whale’s brain makes up as little as 0.005% of its total body mass! Our brains, by comparison, are about 2.5% of our bodyweight. So is brain-to-body mass ratio the true decider of intellect? It’s certainly a better metric to compare between animals, but still one which is deeply flawed.* *It turns out that, all else being equal, brain mass does not scale linearly with body mass. After all, there is a minimum number of neurons an animal needs to function, a concept known as the “grey floor”. Smaller animals tend to have much higher brain-to-body mass ratios, without necessarily seeming any more intelligent. A humble shrew, for example, has a brain which constitutes one tenth of the size of its body! If the metric were reliable, the shrew would be taming us!* *While we’re on the topic, I should mention that the species with the lowest brain-to-body mass ratio of all vertebrates on this Earth is the magnificently named bony-eared assfish. Brains consume huge amounts of precious energy, so in the incredibly barren environment of the deep sea, the bony-eared assfish has done away with most of its grey matter.* *For a fish with such an unflattering name, it is hauntingly beautiful!* *Anyway, it’s clear that raw brain-to-body mass ratio is far from a perfect measure of intelligence; it is too harsh on big animals, and too kind to small animals. Scientists have studied the relative brain sizes of mammals, and come up with a formula that adjusts for this problem. Applying this formula gives a new, more refined metric: encephalisation quotient, or EQ for short.* *In other words, EQ is the ratio of actual brain size to predicted brain size. When we compare different animals’ EQ values, the results line up a lot more with what we would expect, intelligence-wise. * *Humans have the highest score of any animal, at about 7.6.* *The tucuxi, a very interesting type of freshwater dolphin from the rivers of South America, takes second place**. It measures only 1.5 metres in length, and has a bright pink underbelly!* *anta rays have one of the highest EQs among fish, octopuses triumph among invertebrates, and corvids outperform their feathered friends. These results are all exactly what we would predict based on behavioural signs of intelligence. So, is encephalisation quotient really the answer? Probably not. Once again, this method seems to fall short of being perfect.* *On average, birds have much lower EQs than mammals, but there is ample evidence to suggest that birds are incredibly smart**. In fact, all the dinosaurs, not just birds, have surprisingly low encephalisation values. If estimated EQ is to be believed, Tyrannosaurus rex was less intelligent than a slug. Believe it or not, the sauropod dinosaurs have the lowest score of any animal in history ever measured, at as low as 0.01!* *There are several likely reasons for this. The formula for encephalisation quotient was based only on data from mammalian species, so in general it probably shouldn’t be used to compare mammals to non-mammals. Bird/dinosaur cells are much smaller than mammalian cells. For its size, a typical avian brain has twice as many neurons as a standard mammal brain!* *Raw brain size, brain-to-body mass ratio, EQ… all these metrics share a fundamental problem: they’re all based on overall brain mass in some way, and there’s a lot of stuff inside brains that has nothing to do with intelligence. For example, a large portion of whales’ and dolphins’ brain mass is just insulating blubber! There are all kinds of factors like this that really muddy the waters. Perhaps it’s better to just focus on the part of the brain that actually does the thinking.* *The cerebral cortex is thought to be the seat of intelligence in mammals**. This grooved and convoluted outer layer of tissue is responsible for processing our senses, finely controlling our movement, abstract thought, and much more. Non-mammal animals don’t have a cerebral cortex per se, but they always have an equivalent brain region - for example, birds have their dorsoventricular ridge, or DVR.* *So far, the single best predictor of intelligence we have found is the number of cortical neurons; that is, the total number of nerve cells within the cerebral cortex (or equivalent area). Humans have at least 16 billion, which is exceptional! Elephants, despite having a brain twice as large, have about a third as many cortical neurons. However, the real world champion is the orca, believe it or not, with an absolutely astonishing 43 billion cortical neurons!* *In fact, by this measure, humans sit at humble fifth place**. There are four species of dolphins with more cortical neurons, the most of all belonging to the orca. Some might be quick to discredit this method as soon as they hear that it doesn’t put humans on top, and I would encourage those people to keep an open mind. If we’re so, so sure that orcas are less smart than us, perhaps we’re looking at intelligence in the wrong way.* *But that’s a more philosophical discussion for another answer. Anyway, for centuries, humans have been trying to put a number on intelligence, to find some way to quantify it**. None of the metrics we’ve come up with are perfect, but for now, the best we have is the number of cortical neurons. It doubtless has its discrepancies, but overall it seems to be an extremely useful way of comparing animal acumen.* *So, going back to your question, if an elephant’s brain is bigger than ours, why isn’t it smarter? Because the size of a brain, as we’ve seen, has little to do with intelligence. Apologies if this answer was long-winded, though I think we visited some interesting places on our journey through animal minds! Thank you everyone for reading, I hope you enjoyed, and have a great day.* *Q4 Why was the old calendar changed?* *A4 Steve Baker, Senior Software Engineer (2013–present)Sun* *The problem is that the Earth orbits the Sun in 365.2422 days (an “astronomical year”).* *The older calendars used 365 days per year - with a leap day every four years.* *So that’s: 365 + 1/4 = 365.25 days* *But that 365.25 is a little too long - it should be 365.2422.* *Without some kind of a fix - the calendar was slowly slipping away from reality**. The solstices and equinoxes were drifting slowly - but measurably.* *Although the error wouldn’t bother most people - it bothered the Catholic Church A LOT - because they’d gone to a LOT of trouble to formally establish the date of Easter.* *Easter is defined as: The first Sunday after the full Moon that occurs on or after the spring equinox. If the full Moon falls on a Sunday then Easter is the next Sunday.* *But if you have the date of the equinox wrong - by even just one day - then you could have Easter an entire week away from when it should be…and that would evidently displease God and “Very Bad Things” would happen.* *So it was decided to skip the leap day every 100 years.So - for example - the year 1900 - despite being a multiple of 4 years was NOT a leap year.* *That gave a year to be 365 + 1/4 - 1/100 = 365.24 days - which is pretty close.* *But the next rule is that a century year that’s an exact multiple of 400 years IS a leap year - which is why the year 2000 was a leap year - despite being a multiple of 100 years.* *So now we have:* *356 + 1/4 - 1/100 + 1/400 = 365.2425* *So we’re still not 100% perfect - but the error of a single day every few thousand years is actually OK* *because the length of our orbit does change a tiny bit each year depending on the location of Jupiter - so going for more accuracy than that is over-kill.* *Q5 What is the craziest domesticated animal to ever exist?* *A5 Gary Meaney, author of Zoology's Greatest Mystery (2022)4y* *In my opinion, that honour goes to the domestic pigeon**. In the 10,000 years since their domestication, the birds have been selectively bred into countless bizarre forms, collectively known as “fancy pigeons”.* *Ever wondered if there was a pigeon with the** erectile fan-shaped tail of a turkey? Probably not, but check.* *What about a pigeon with a huge puffy crop? Check.* *Pigeons with curly feathers on their wings? Check.* *Pigeons with huge feathers on their feet and powdery down? Check.* *Pigeons with fleshy, flower-like wattles all over their faces? Check.* *Pigeons with that, plus scrawny giraffe necks? Check.* *Flightless pigeons that look and act like chickens? Check.* *Pigeons with enormous ruffs like parka hoods? Check.* *Pigeons with virtually non-existent beaks? Check.* *Bug-eyed pigeons? You guessed it, check.* *In a way, it saddens me that we’ve practically engineered these natural creatures to suit our strange desires. At least they’re not unhealthy,** though - unlike so many poor dogs, especially purebreds.* -- You received this message because you are subscribed to the Google Groups "iyer123" group.
