Q2 What are some interesting facts which are not commonly known? A2 Alexander Brown, Master in Psychology, Columbia University (Graduated 2015) June 8
1. After a kidney transplant, you actually have three kidneys. My note-Original kidneys are not removed, new one is added KR: It is partially correct; but though risky, in many cases, removal was also done due to extrenous reasons. The new kidney is placed in the low abdomen and groin area and not in the natural place for your kidneys. Removing the old kidneys is very risky and should not be done unless there is uncontrolled infection, high blood pressure, or the kidneys are markedly enlarged such as with polycystic kidney disease (PKD). 2. The original name for the search engine Google was Backrub. It was named Google after the googol, which is the number one followed by 100 zeros. KR Again thinks ITS and Gopalakrishnan are the same; ITS came later; Gopalakrishnan existed even without ITS; The status of the business is continuous only for the proprietors and not for Law. As PAGE was consuming the data from STANFORD, he called it BACK-RUB. Later his classmate suggested googolplex > 1 followed by 100 zeros. But Page typed in search for the existence of the name as GOOGOL, BUT TYPED AS GOOGLE. There was nothing like that so fixed as company name when the latest company was invoked under the law. As ITS has nothing to do with Gopala ,legally, Back rub and Google were/are different. 3. The “word of the year” in 2015 was an emoji. The “smiling with tears of joy” pictograph “best reflected the ethos, mood, and preoccupations of 2015”, Oxford dictionaries said. KR Half-truth; every year has a word which the same dictionary says , which may be reffered to in the web site. 4. According to several cannibals, human meat tastes very similar to pork. (Mind-blowing…) Not verified by me KR Again not checked facts fully. Seabrook noted that, in raw form, human meat looks like beef, but slightly less red, with pale yellow fat. When roasted, the meat turned greyish, as would lamb or veal, and smelled like cooked beef. Purportedly, the term long pig is a translation of a phrase used in the Pacific Islands for human flesh intended for consumption. Early explorers and missionaries who contacted cannibal Pacific Islanders were told that human flesh tastes similar to pork, thus the term long pig. So, it does not taste like pork but only like Beef. The reason is that uneducated people say it as a comparison which is not true. 5. Fear can actually feel good if you are not really in danger. KR HOW? Fear starts in the part of the brain called the amygdala. According to Smithsonian Magazine, “A threat stimulus, such as the sight of a predator, triggers a fear response in the amygdala, which activates areas involved in preparation for motor functions involved in fight or flight. 6. If you’re shot by a sniper, you’ll be dead before you hear the gun. KR Another falsity. A Remington Model 700 chambered in .308 caliber has a report of 140 dB. The decibel scale starts at zero (0dB), which is the lowest sound pressure a human ear can hear. That’s not to say there is no sound below 0dB, there’s plenty, we just can’t hear it. Your dog probably can. So we need to find the distance at which 140 dB is reduced to zero by the inverse square law. I1 = 140 (db) I2 = ~0 (db) d1 = 1 (foot) d2 = distance from the source such that I2 = ~0. In order to get to nearly 0db, the distance required is around 29,527,559 feet, or 5592 miles! Obviously this is incorrect, yeah? That’s a quarter of the way around the planet! Well, like I said, it’s a theoretical calculation based on a perfect sphere of sound waves emanating from a point source (did I mention that?) Such a situation does not exist in the real world. For example, I am within less than 100 miles of a rifle range. I’ve never heard a single report from that rifle range until I got within a mile or so. This is due to the effects of the ground reflection, air density, temperature, humidity, trees, hills, buildings, billboard signs, telephone poles and other objects in the way. There are also many thousands of sound sources that may cancel out or distort the sound waves that originated at the muzzle of the rifle. A jet flying overhead cancels out a lot of sound due to it having a large unencumbered path for its sound waves to travel. So, in spite of the usefulness of the inverse square law, it’s only telling us the theoretical limits of our ability to hear a distant sound. It’s also possible for a sniper to set up a shot that nobody in the target area can hear. Using background noise and reflective/diffusive structures between the sniper and the target can mask the sound. It’s also very difficult due to reverberation and reflection (echoes) to tell where a shot originated. A bullet passing over a wall will sound like it came from the wall due to its sonic boom reflecting off the wall. Also, the sniper’s side of the wall will reflect the report back towards the sniper. Reflected sound waves will not reach the target area, since they are now traveling in the opposite direction. The answer to this question really depends on more factors than we can calculate without a sophisticated simulation. 8. Tom and Jerry was originally named Jasper and Jinx. KR 1940 episode. Then those names were in the market as product rememberable so named them as Jinx. When filmed, in order to publicise the studio announced a contest for $50 and the drinks in the market popular was Tom and Jerry so one named it and hence took the publicity stunt by Walt-Disney. 9. Otters sleep holding hands. (Awwww.) KR Many animals and humans do that . 10. It's totally legal to escape from prison in some countries. Several countries, including Mexico, see the desire to escape prison as basic human nature rather than an unlawful act. KR In the Cowboy days and not now. 11. Around 80% of images online are of naked women. KR HOW DID THEY KNEW?
