​​What Are Olympic Gold Medals Actually Made Of? If you’ve watched the Olympics, you may have wondered to yourself: Are Olympic medals real gold? And if they are, how much is an Olympic medal worth if an Olympian chose to sell theirs? We break down those answers ahead. Olympic gold medals have some gold in them, but they’re mostly made of silver. According to the International Olympic Committee (IOC), gold and silver medals are required to be at least 92.5 percent silver. The gold in gold medals is in the plating in the outside and must consist of at least 6 grams of pure gold. As fans may have noticed, many gold medal winners will pose with their medal in their mouth on the winner’s podium, as if they’re about to take a bite out of it. While real gold dents, viewers won’t see much of a difference in Olympic gold medals as they’re made of mostly silver. Silver medals, on the other hand, are made of pure silver, while bronze medals are 95 percent copper and 5 percent zinc. The shape of medals is usually circular with an attachment for a chain or a ribbon. The minimum diameter is 60 millimeters, and the thickness is a minimum of 3 millimeters. Medals should weigh between 500 and 800 grams (17.64 to 28.22 ounces). Gold medals weighing about 556 grams in total, while silver medals weigh 550 grams and bronze medals weigh 450 grams.

​​What Was The First Animal In Space?  While many flights into space may have accidentally carried bacteria and other forms of life on board, the first living creatures intentionally sent into space were fruit flies. These were transported aboard a V2 rocket on 20 February 1947.    The fruit flies were launched from White Sands Missile Range in New Mexico as part of a research mission. The unnamed rocket travelled 67 miles into the air before parachuting back to Earth. NASA currently recognises the altitude of 66 miles (100km) as the point where space officially begins. Therefore, the fruit flies are considered the first animals ever to reach the final frontier.   The V2 rockets were the world's first long-range guided missiles and were used by Germany during World War II. The missiles could fly at a top speed of 3,500 miles per hour and strike targets over 200 miles away. Following the war, the US seized many of these rockets and used them for research purposes, laying the groundwork for future space launches. Wernher von Braun, who designed the V2 was even involved in the designing of the Saturn V rocket for NASA.    The flies were the perfect passengers for the flight as their compact size, and relatively light weight made their storage easy and conserved on fuel consumption.    At the time, little was known as to the effects of cosmic radiation on organic matter. As fruit flies have a similar genetic make-up to humans, they were seen as an eligible subject for testing and research. On the safe recovery of the flies' capsule, the scientists found that the flies' genetics had not been mutated by the radiation, which paved the way for future human spaceflight. 

​​​​Why White Powder used inside Electrical Cables? According to capacity, applications of the electrical cables different types of powder are used such as talcum powder, magnesium oxide(MgO) Powder, Swellable powder, Chalk Powder, etc. ◆Talcum Powder in Electrical Cables: Talcum Powder is used in some low current-carrying cables such as computer power cable to make it flexible, to stop the internal wires from getting stuck to the outer rubber casing. When a cable is used over a long period of time, its outer rubber gets sticky and can be broken down. So to prevent this problem talcum powder is used in some electrical cables. ◆Magnesium Oxide Powder in Electrical Cables: Magnesium oxide powder is used in high current carrying cables, Mineral Insulated(MI) cables. Magnesium oxide powder has two very useful properties that are high thermal conductivity, low electrical conductivity. Magnesium oxide powder gives a lot of features and advantages in an electrical cable which are given below, When a high current flowing through a cable, heat produced which can damage the cable. Due to the high thermal conductivity property, Magnesium oxide powder can conduct the heat from inside of the cable to outside and prevent the damaging of the cable from the heat. Due to low electrical conductivity property, magnesium oxide powder provides good electrical insulation. Magnesium oxide powder provides good lubrication to electrical cables. Magnesium oxide powder makes electrical cables fireproof. Magnesium oxide powder makes electrical cables flexible. ◆Swellable Powder in Electrical Cables: Swellable Powder is used in electrical cables to block the water and to eliminate the moisture issue. These powders can form a gel-like material when contacting with water and block the flow of water. These powder swell and expands to block the water permanently. ◆Chalk Powder in Electrical Cables: Chalk Powder used in some cables to provide fire resistance. To prevent wires inside a cable from fire, chalk powder is used in some electrical cables.

​​What Is Hydroponics? Hydroponics comes from the ancient Greek formation of “hydro”, meaning water, and “ponics”, meaning labor. The water is doing the work here and enabling the fast growth of plants.  At its core, hydroponics is a method of growing plants. But instead of using soil, hydroponics depends on a water-based nutrient-rich solution. The idea may seem like a novel “hack”, but has actually been around for thousands of years and helped to enable population growth as the availability of arable land decreases. As we discussed earlier, the ability to not use soil and instead use organic substances like perlite, coco coir, rock wool, clay pellets, peat moss, or vermiculite has provided numerous benefits to growers everywhere.  Increased growth results from allowing the roots of each plant to come in direct contact with the nutrient solution. This is further enabled by the increased access to oxygen compared to its soil counterpart. 

​​​​How Does Inflight Wifi Work? In the past, there was no connectivity to mobile towers few hundred feet above the ground (after takeoff). Travelers have to wait until the aircraft lands at the airport to use their Smartphone. This is an old story, technology has been changed a lot since then. Similar to our mobile network, Inflight Wi-Fi connectivity requires a base station to send and receive signals. It works in two modes; Ground based connectivity and Satellite based connectivity. Air to Ground (ATG) Ground based connectivity: Ground based connectivity also known as Air to Ground connectivity works exactly like our conventional mobile network. It has a base station on the ground with antenna arrays facing upwards to maintain signal connectivity to moving airplanes. Network of base stations are required to cover a large geographical area. Transceiver antenna module will be installed on the belly of an airplane. Latency is lower since the airplane is only 35000 feet above ground (average approximation) Less complex compared to satellite based system. Operators can make use of existing network for this task. Cost effective solution and infrastructure. Easy to maintain the system. Satellite based connectivity: Satellite based connectivity uses a network of satellites dedicated to provide data connectivity to moving airplanes. Transceiver antenna module will be installed on top of airplane. Each satellite can server more number of aircrafts at same time. Fast network using higher bandwidth signals compared to ground based system. More immune to atmospheric changes.

​​How Long Can a Cockroach Live Without Its Head? Even for major catastrophes like losing a head, cockroaches don’t bleed very much. Unlike humans, they have an open circulatory system: A system for distributing blood through their bodies that doesn’t depend on a closed network of arteries and veins. Their blood doesn’t pump under pressure like ours, but just sort of sloshes around, making its way into the cockroach’s tissues. The great thing about this system, if you’re someday going to be headless is that when a major wound occurs, blood doesn’t suddenly get forced out. For a cockroach that loses its head, the blood just clots at the neck. The cockroach will have a nasty scab for sure (where its head used to be), but it won’t die from loss of blood. Unlike humans, cockroaches don’t breath through a nose or their mouth. Instead they breathe through small holes in their bodies called spiracles that don’t need a brain to direct them. No nose, no mouth, and no need for a brain to regulate your breathing means that you can breathe all you want to without a head. But it is going to die from being unable to eat. And well before that, it’s going to die from thirst. A headless cockroach has no mouth to drink with and will be dead from dehydration in less than a week. Which brings the total day count from the moment it loses its head to the moment it loses its life to somewhere around 7 days or less.
