N Sekar ----- Forwarded Message ----- *From:* 'N Sekar' via KeralaIyers <[email protected]> Thanks. Re: Q 7 where it is stated in the second last para, legitimisation to marriages between Yavanas and Indians in both the Empires brought back memories of the famous novel "*Yavana* Raani" by the late author Chandilyan. I am a fan of his. I must have read it several times, it was gripping and was set in historical background - taking us back to the Chozha period, with Karikalan featuring prominently. The main character in that book Ilanzchezhian is an unforgettable character. Although he has written several other novels, in my opinion Yavana Raani is the best. This and Kalki's "Ponniyin Selvan" are my all time favourites.

A2 Teamedical, Experienced Medical Team Nov 19 When it comes to eating fruits, it is the best way to enjoy the healthiest and most natural sources of vitamins and minerals. However, not all fruits are created equal, and certain combinations don’t necessarily pair well together. Combining certain fruits can create an imbalance of vitamins and minerals, as well as produce unpleasant feelings in the body, such as headaches, stomach aches and other digestive issues. So, what are the fruits you should avoid eating together? First and foremost, you should never mix citrus fruits and bananas. Citrus fruits are acidic and tend to be too harsh on the stomach when eaten in large doses. Meanwhile, bananas are rich in magnesium and can create an overload of minerals in the body when paired with acidic fruits. Also, it’s best to avoid combining watermelon with other fruits, as it contains a lot of water and can create a very watery texture that doesn’t pair well with other fruits. Another pair of fruits you should stay away from is dates and avocados. Dates are high in sugar and can overwhelm the body when combined with avocados, which are heavy in monounsaturated fats. You should also avoid eating apples and pears together, as apples are acidic and pears can be too heavy on the stomach. Finally, mixing melons and grapes is not recommended either. Melons are extremely high in sugar and can cause a sugar rush if mixed with grapes. Additionally, the combination can be hard for the body to digest properly, leading to uncomfortable digestive issues. It’s best to keep these combinations in mind when eating fruits. Although some of these combinations might still be enjoyable, you should be aware of the potential side effects that could be experienced. Eating the right combinations of fruits can help ensure you get the most out of the nutrition that fruits provide. Q3 How can the universe be so orderly among infinite possibilities? A3 Steve Baker, Senior Software Engineer (2013–present)4h If you dissolve as much salt as you can in a shallow pan of hot water - then allow it to cool - and then evaporate - you’ll find that most of the sodium-chloride molecules that had been bouncing around at random in the liquid have spontaneously formed perfect cubes - big enough to see easily with the naked eye. This is “order from chaos”. In the case of the universe, the organizing force is “gravity” pulling things together - opposed by the electromagnetic forces between atoms keeping everything from collapsing into a black hole. This is why we have planets, stars and galaxies….that’s all just gravity. Stars form from lighter elements - hydrogen and helium - and gravity pulls those elements together with enough force to cause a fusion reaction that results in sunlight. Planets form from the heavier elements - iron, carbon and so forth. Q4 What are some historical records of the reversal of the Earth's magnetic field? A4 Sangram Sagar,Blogger, Content Writer1y In Ngawha, on the North Island of New Zealand, an ancient tree has been discovered that contains a record of a reversal of the Earth's magnetic field. The tree - an Agathis australis, also known as the Maori name kauri - was found during excavation work for the expansion of a geothermal power plant. The tree was buried 9 meters deep and measures 2.4m in diameter and 30m in length. Carbon dating indicated that she lived for 1,500 years, between 41,000 and 42,500 years ago. “There is none of this anywhere in the world. This Ngāwhā kauri is unique.” The lifespan of the kauri tree covers a point in Earth's history when the magnetic field nearly reversed. Magnetic north and south have shifted positions, but a complete reversal has not taken place. It was almost a reversal. The Earth's magnetic field is believed to be generated by the iron in the planet's core. It produces electrical currents that extend into space as they move. The magnetic field is really like a barrier that protects the planet from the solar wind, which is a stream of particles from the Sun that could remove the Earth's atmosphere, as happened on Mars. With the magnetic field, they are attracted to the poles. When the magnetic field reverses, it weakens and the planet suffers more from the effect of the Sun's radiation. Scientists have already linked extinction events to reversals of magnetic fields. The rings of this kauri tree have a complete record of this near reversal, and this is the first time a tree that lived through the entire event has been found. Scientists are now analyzing samples from the tree and are led by Chris Turney of the University of New South Wales, an expert in paleoclimatology and climate change for the past 40,000 years. The research is being funded by the Research Council of Australia. Turney explained: “The precious thing is that this huge lone tree grew for about 1700 years in a remarkable period in our planet's history, when Earth's magnetic field reversed 42,000 years ago, a period known as the Laschamp Excursion. We're doing a detailed analysis of carbon-14 in the various rings of this tree. In the last 83 million years, there have been 183 magnetic pole reversals. This process takes about 7,000 years to complete. Monika Korte, scientific director of the Niemegk Geomagnetic Observatory at GFZ Potsdam, Germany, says: “It is not a sudden movement, but a slow process, during which the strength of the field becomes weak, most likely the field becomes more complex and may show more than two poles for a while, and then it strengthens and aligns itself in the same direction. opposite direction." According to NASA, magnetic field reversals occur at random intervals, although over the last 20 million years it appears to have settled into a pattern, occurring once every 200,000 to 300,000 years. The last total reversal took place about 780,000 years ago. Recently, scientists announced that the magnetic north pole had moved unexpectedly. Instead of constantly tracking from the Canadian Arctic towards Siberia, it sped up so much that researchers had to update the World Magnetic Model (WMM), which is a representation of Earth's magnetic field. It is used extensively in navigation by the US Department of Defense, the UK Ministry of Defense, and many civilian systems - so knowing exactly where the north and south magnetic poles are is of utmost importance. Q5 How does gingerol help in boosting metabolism? A5 Shnayas,BCA from Indira Gandhi National Open University (IGNOU) (Graduated 2022)1h Gingerol, found in ginger, is believed to boost metabolism through its thermogenic effect, which increases the body's production of heat. This can potentially lead to an increase in calorie burning and fat loss. Gingerol may help improve insulin sensitivity and reduce inflammation, contributing to overall metabolic health. However, ginger can be a beneficial addition to a healthy diet, it's important to note that its impact on metabolism is just one factor, and lifestyle choices play a significant role in overall metabolic function. Q6 What are some mind-blowing facts that sound unreal but are actually true? Ryder Lee,Lives in New Hampshire Updated 5y Here are some: There are no bridges over the Amazon River. Surprisingly, it took the person who invented the Rubik’s Cube an entire month to solve it after they created it, and yet the current record in the world is less than five seconds. Sunsets are blue on the red planet, Mars. Sunsets are red on the blue planet, Earth. Technically, when you’re looking up at the sky, you’re actually looking “back in time”. For example, the bright star Vega is relatively close to us at 25 light-years away, so the light we see left the star 25 years ago. The tallest and largest volcano in the solar system is located on the deserted planet of Mars, a neighboring planet to Earth. The shield volcano is named “Olympus Mons”, and is 16 miles (24 kilometers) tall. This means that this volcano is approximately three times taller than Mount Everest. There could actually be around 500 million planets that could support life like Earth can in our galaxy. Q7 Why did Chandragupta Maurya marry Helina? Is Helina responsible for ending the Mauryan dynasty? A7 Rachel Gellar,Student 11h Chandragupta Maurya married Helena in a peace treaty in 305 BCE. She was surrendered to him by her father Seleucus. It's not known who put this condition first. Intermarriage for making peace was common back then so it's not someone unusual. Helena was half persian. She was favourite daughter of her father and therefore surrendering her was a huge deal. As a young girl she was married to Chandragupta who was in his 30s then. His son Bindusara was already 15 or 16. He brought his new wife to Sindh at spent some time with her there. He gave her gifts which included moon shaped earrings. Later he also brought her to Patliputra where she gave birth to his children. Their marriage established Epigamia and provided legitimisation to marriages between Yavanas and Indians in both the Empires. No, she was not responsible for any decline of Mauryans. -- You received this message because you are subscribed to the Google Groups "iyer123" group.
