CULTURAL QA 01202520 SIMPLE BRIEF QA- BASE QA FROM QUOTA –Compiled
Q1 What is wrong about August 15th in the calendar for the year 1947? KR What a finding to celebrate!!! Q2 Can an ostrich outrun a lion and a tiger? KR Facts are: Here are the approximate running speeds for the animals you mentioned: Ostrich:Maximum speed: 60-70 km/h (37-43 mph) Sustained speed: Around 50 km/h (31 mph) for longer distances. Lion: Maximum speed: 80 km/h (50 mph) Sustained speed: Lions can only maintain this for short bursts, typically 100-200 meters. Lioness: Maximum speed: 85 km/h (53 mph) Similar to lions, they can only sustain this speed for short bursts. Tiger: Maximum speed: 49-65 km/h (30-40 mph) Tigers are sprinters and cannot maintain this speed for long distances. Cheetah: Maximum speed: 93-120 km/h (58-75 mph) Cheetahs can maintain their top speed for about 20-30 seconds, covering distances up to 500 meters. These speeds vary depending on the individual animal's age, health, and environment. Cheetahs are the fastest land animals, while ostriches are the fastest birds on land. Besides the ostrich, no other birds are notable for running speeds. Instead, animals like the cheetah, pronghorn antelope, and springbok are known for their incredible speeds on land. Q4 Why does the Moon's gravity cause tides to the oceans, but the Sun's gravity doesn't? Chalkis (or Chalcis) is a city on the island of Euboea (Evia) in Greece. It holds historical significance as a prominent city in ancient Greece and has connections to the philosopher Aristotle. Here's the connection: Aristotle and Chalkis Aristotle's Final Days: Aristotle, the famous Greek philosopher, spent his last days in Chalkis. After leaving Athens due to political unrest and hostility toward Macedonians (he had connections to Alexander the Great), Aristotle sought refuge in Chalkis around 322 BCE. Death of Aristotle: He passed away in Chalkis in the same year, likely due to natural causes, though some sources suggest it may have been a stomach illness. Aristotle was about 62 years old at the time of his death. Legacy in Chalkis: While there isn’t extensive physical evidence directly tied to Aristotle in Chalkis today, his connection to the city adds to its historical and cultural importance. Let me know if you'd like to learn more about Chalkis, Euboea, or Aristotle's life and works! AND NOT MUCH SPOKEN ABOUT TIDESIN CHALKIS. II Yes, the effects of the Moon's and Sun's gravity on sea waves—commonly observed as tides—have been scientifically proven and well-understood. This phenomenon is explained through the principles of gravitational forces and the Earth-Moon-Sun interactions. Here's a detailed breakdown: 1. How the Moon's Gravity Affects Tides The Moon's gravitational pull creates a tidal force on Earth. The side of Earth facing the Moon experiences a stronger pull, causing the ocean to bulge outward, creating a high tide. On the opposite side, where the Moon's pull is weaker, another high tide occurs due to the Earth's motion and the water "lagging behind." Areas in between these bulges experience low tides. 2. Sun's Contribution to Tides also contributed in spite of distance ona particular conditions: The Sun, despite being much farther away, also exerts a gravitational pull on Earth's oceans. When the Sun, Moon, and Earth align during new moon and full moon phases, their combined gravitational forces create spring tides (higher high tides and lower low tides). During the first quarter and last quarter moon phases, the Sun and Moon are at right angles to each other, causing neap tides (lower high tides and higher low tides). 3. Scientific Proof Isaac Newton's Law of Universal Gravitation: Newton first explained tides using his theory of gravitation, demonstrating that celestial bodies exert forces on each other. Astronomical Observations: Modern observations confirm the Moon's orbit and gravitational influence on Earth. Satellite Measurements: Space-based tools, like the TOPEX/Poseidon satellite, measure sea levels and tides with high precision, confirming gravitational models. Oceanography Studies: Tidal patterns worldwide align perfectly with gravitational predictions based on the positions of the Moon and Sun. 4. Waves vs. Tides It’s important to note that tides (long-term, gradual water movements driven by gravity) are distinct from waves, which are primarily caused by wind and other local factors. However, tidal forces do influence water movement at a large scale. 4 I have not written here our Vedic observations.

A1 Gopalkrishna Vishwanath, Have always been interested in History, once I didn't have to learn it formally Aug 15 Nothing is wrong with August 15th. It is a very RIGHT date. India won its Independence on August 15th. But in this old calendar something appears wrong at first sight! Look at it carefully. What appears wrong? August 15th is not shown in RED. It was not a holiday! Why? Look at the year.1947! This calendar was published before August 15th 1947 and so it was not a holiday. Q2 Can an ostrich outrun a lion and a tiger? A2 Hushe, Animal enthusiast Updated Dec 3 “Can”? Most definitely. Listen, Lions and Tigers are both exceptionally fast and explosive predators. They have just about every single advantage on the ostrich. But Ostriches aren’t just the fastest birds, they are the fastest two-legged runners in the animal kingdom, now, an exceptionally quick lioness would probably catch an ostrich if they were in a straight line race. Here are some statistics: Male lions can run at speeds of up to 35mph - females are faster Male tigers can run at speed of up to 35mph - females are faster *Ostriches can top out at about 43mph* So, in a straight line. A particularly quick tiger/lion could catch the ostrich, however ostriches can maintain those speeds for a longer time than either cat. And they always have a fairly big head start on the cat. Ostriches have exceptional vision, and they will notice the large predator very early - before they get close enough to pose a chasing threat. If you’re not a cheetah, running down an ostrich is very difficult Q3 Have vultures ever been used for commercial purposes? A3 Sean Kernan,4y *Oil and gas companies will sometimes use Turkey vultures to help spot gas leaks.* Ethyl mercaptan is added to natural gas to help people smell when there is a gas leak (otherwise they often won’t know, making the leak potentially lethal). This smell is also emitted from a rotting carcass. Turkey Vultures happen to be very attuned to this smell. Natural gas company employees know to take note if they see a bunch of turkey vultures converged near one of their pipes or facilities because that usually means there is a leak somewhere. The vultures are probably confused, wondering where their dinner is when it is in fact just a metal pipe. It’s a rather clever, albeit indirect way of dispatching wildlife to help solve business needs. Vultures, aka “nature’s cleanup crew” are one of the more underappreciated animals. In nature, there is no malice and no remorse. And absolutely nothing goes to waste. Q4 Why does the Moon's gravity cause tides to the oceans, but the Sun's gravity doesn't? A4 Alexander Mathey, Former Chemical Engineer, retired, lives in Athens, GR Updated Nov 12 In the town of Chalkis in Greece, capital city of the island of Euboea, there is a narrow strait between the island and the mainland, known as ‘The strait of Euripos’ A strong tidal current forms along the strait, whose direction and strength is dependent on the position of the moon. The moveable bridge can only then be opened to let ships pass by, when the waters calm during the change of direction. The phenomenon is due to the difference in level between the North Aegean Sea and the South Aegean Sea, caused by the movement of the Moon. It is said that Aristoteles, who lived the last years of his life in Chalkis and died there in 322 BCE, was utterly desperate that he could not give an explanation for the phenomenon. To come back to the subject of the sun’s gravity pull: The locals in Chalkis have noticed, that at New Moon and at Full Moon, when the Sun, Earth and Moon are aligned, *the movement of the waters through Evripos’ Strait is regular with change of direction about every 6 hours.* All other times, when the Sun is at an angle to the axis Earth - Moon, the movement of the waters becomes irregular and unpredictable.So, the gravitational pull of the sun may not be strong enough to cause tides of its own, but it is strong enough to disrupt the tides caused by the moon. Q5 Can you tell a bank joke? A5 Malouke Douma, Jan 2 An old Native American man needed to borrow $500, so he went to the local bank and asked to speak to the Loans Officer. The banker welcomed him and said he had to fill out a loan application. So, the banker took a form from his desk and began asking questions. "What are you going to do with the money?" the banker asked. "Buy silver, make jewelry, then sell it," the man replied. "And what do you have for collateral?" asked the banker. The man said, "I don’t know what collateral is." The banker explained, "Collateral is something valuable that we hold onto in case you can't pay back the loan. Do you have any vehicles?" "Yes, I have a 1979 Chevy pickup," the man answered. The banker shook his head, "That won’t work. How about livestock?" "I have a horse," the man said. "How old is the horse?" the banker asked. "I don’t know, it has no teeth," replied the old man. After a few more back-and-forth questions like this, the banker finally decided to grant the loan to the old man. A few weeks later, the old man came back to the bank. He pulled out a big roll of $100 bills from his pocket and said, "Here’s the $500." "Business must be good!" the banker said. "What are you going to do with the rest of the money?" "Keep it close to me," the old man answered. "Why don’t you deposit it in the bank?" the banker asked. The old man said, "I don’t know what deposit is."The banker explained, "You just put the money in our bank and we’ll take care of it for you. Whenever you need it, you can take it out." *The old man leaned over the desk, looked the banker in the eye, and asked, "What do you have for collateral?"* *Gopalakrishnan 21-1-2025* -- To go to your groups page on the web, login to your gmail account and then click on https://groups.google.com/ --- You received this message because you are subscribed to the Google Groups "iyer123" group.
