There’s so much to love about lemonade stands, especially when you’re the kid in charge of it. Sadly, a little girl named Maddy had to close her lemonade stand early when two teens decided to rob the young girl. The robbery took place in Saskatoon, Canada. By the time Maddy’s parents were able to call the police, the boys had already fled the scene. So, when officers did arrive, they began to search for the teenagers. Then, within minutes, the two robbers were located. One was a 14-year-old with knife and the other was a 16-year-old who had outstanding warrants. Although action was taken swiftly, the damage had been done. The boys had taken juice, money, and candy, leaving the girl sick to her stomach, according to mom, Jade Floata. Thankfully, however, her community has been quick to show her support! Facebook “[Maddy’s] out every day. The neighborhood knows her,” Jade shares. “She has her regulars. I was in the living room and I seen that there was a teenage boy there and I knew something wasn’t right because he was helping himself. He was taking the lemonade, cup after cup, and then crushing them and throwing the cups, like at her, on the lawn.” When Teens Rob a 7-Year-Old’s Lemonade Stand, Her Community Has Her Back The support started when Cst. Duke, the officer who arrested the teens, returned to Maddy’s home for a glass of her famous lemonade. But that’s just the start! As word quickly spread about what had happened to Maddy, the Saskatoon Berries Baseball formulated a plan to give the 7-year-old the spotlight she deserves! “Jam Fam! We’re not gonna let a couple rotten berries ruin this gals summer,” their post reads. “Maddy and her big sister will have their lemonade stand set up at our game TOMORROW night in the plaza. Let’s show her how sweet we all know Saskatoon can be!” To say that the Saskatoon community showed up for Maddy would be an understatement! This young entrepreneur was delighted by the love and care she received during last night’s game. So many people lined up to get her lemonade, helping the little girl feel safe and supported. What a beautiful way to combat such a scary, sad experience! “Maddy, you can sell lemonade at our games whenever you want,” the Saskatoon Berries Baseball shares.

Cat ownership would be a lot easier if our pets could tell us their thoughts. However, until someone develops a cat-to-human translator, we have to use context clues and our pet’s body language to decipher their moods. A cat’s tail is one of the most expressive parts of their body. So, if your cat’s tail is twitching, you’re probably wondering what they’re thinking. Unfortunately, a quivering tail can mean many different things, so you’ll need to put on your thinking cap to determine what’s going on. From the thrill of practicing their hunting skills to the frustration of aggravating situations, there are many potential reasons for your cat’s tail twitching. Read on to learn more so you can begin to better understand your cat’s mood and the driving forces behind this behavior. The 6 Reasons Why Cats Twitch Their Tails 1. They’re Hunting Cats will sometimes twitch their tails because they’re hunting or playing. This happens when they’re focused intensely on their prey, whether it’s a real-life mouse or a fluffy one you just bought from Amazon. Image Credit: Viacheslav Lopatin, Shutterstock 2. They’re Excited When children are happy and excited, they often jump up and down as a way to release their pent-up energy and express their enthusiasm. Our cats don’t have the same ability to show their happiness, so a quivering tail can also mark anticipation and excitement. 3. They’re Annoyed When your cat twitches the tip of their tail strongly from side to side, it may be that they’re mildly irritated or frustrated. This could be a warning sign that your pet isn’t fond of something you’ve been doing, but they’re not quite at the point yet where they’re going to take the next step and act on their annoyance. Image Credit: Alexander Sobol, Shutterstock 4. They’re Feeling Aggressive Tail twitching is sometimes also associated with aggression. The more your pet’s tail moves back and forth, the less happy they may be. Rapid tail movements can mean they’re issuing a threat to you or another pet in the home. You might also see other aggressive behaviors, such as growling or hissing. Their tails may also thwack audibly on the floor or nearby walls. 5. They’re Spraying You know your cat is spraying when they stand up, hold their tail straight up in the air, and put their rear end toward a target (e.g., walls, bedding, curtains, etc.). Their tail will be quivering, and they’ll spray urine onto an object. Spraying is most likely to occur in cats that have reached sexual maturity, and it can occur in both male and female cats. It happens most often in intact males and females in heat, though those that have been spayed or neutered can also spray. Image Credit: Elisa Putti, Shutterstock 6. They Have Feline Hyperesthesia Syndrome Feline hyperesthesia syndrome (FHS)—also known as “twitchy cat syndrome”—is a rare condition that causes increased sensitivity to touch and uncontrollable muscle contractions. FHS is poorly understood, and its root cause is still unknown, though it is most often attributed to neurological, psychological, or dermatological causes. Before it can be diagnosed, other conditions that cause similar signs must be ruled out. Cats with this condition may quiver their tail, but they’ll often exhibit other signs, including: Rippling or twitching of skin on the back Biting or licking themselves (particularly in the back, side, and rear regions) Pain or discomfort when petted Dilated pupils Brief bursts of running Tail chasing How Can I Know Why My Cat’s Tail Is Twitching? With so many reasons for your cat’s tail twitching, it can feel impossible to determine what your cat is feeling. However, it’s actually relatively easy if you stop and consider your behavior and your kitty’s current environment. Think about what your kitty is currently doing, their body language, and what’s going on around them to determine the exact reason for your pet’s tail twitching. For example, a cat that your toddler is tormenting is unlikely to be twitching their tail out of excitement, especially if their ears are pulled back and they’re staring your child down. It’s much more likely in this scenario that your cat is feeling annoyed and ready to strike. Likewise, if you’re using your cat’s favorite toy to play with them, it’s unlikely they’re twitching their tail because they’re spraying or feeling aggressive. Image Credit: Africa Studio, Shutterstock What Else Your Cat’s Tail Cat Tell You Cats exhibit other tail postures aside from twitching because it’s one of the few ways they can convey their mood and communicate with other cats and humans. Question mark tail Friendly, playful Puffy tail Afraid, defensive, or aggressive Low tail Unease or fear Tucked under: Fearful or anxious Straight up: Confident, happy, friendly Wagging: Angry, frustrated Slow swish: Focused, potentially hunting Quick thrashing: Annoyed, uncertainty How Else Do Cats Convey Mood? Cats don’t only use their tails to convey their mood. Other subtle (and not so subtle) body language cues include: Facial expressions. The ways your cat moves their eyes, ears, and mouth can indicate their mood. Cats feeling relaxed will have normal eye and ear positioning, while those feeling angry will have erect ears and narrowed eyes. Cats with flattened ears and dilated pupils may be fearful. Eye contact. How much eye contact your cat is holding can tell you how relaxed or confrontational they’re feeling. Those slow blinking with a calm stare may feel comfortable and composed, while those staring without blinking may be challenging you. Posture. Cats exhibiting the classic black cat Halloween pose with an arched back and bottle brush tail are feeling aggressive or defensive, while those stretched out with their bellies up are relaxed and comfortable. Image Credit: Ian McGlasham, Shutterstock Final Thoughts As you can see, a cat’s tail twitches can mean a lot of things. It’ll be hard to determine the exact reason behind your pet’s tail movements without also taking into account their body language and context clues from their environment. However, once you consider what else is happening in your cat’s world and how to read their body language, you’ll be an expert on your pet’s moods and feelings.

Global Positioning System (GPS) is widespread these days, helping you navigate to your destination, and also revealing when runners may have cheated in marathons by using a car.Though it requires you to be able to launch many satellites into space, the idea behind GPS is actually pretty simple, at least mathematically. Orbiting 20,200 kilometers (12,550 miles) above the Earth is a constellation of satellites, arranged in a way where you can view at least four satellites from wherever you are on the planet. These satellites contain within them several precise atomic clocks, and broadcast continuously their position, and the time that the signal was sent. The receiver – be it your sat nav, or a tracker attached to a pack of wolves – does the locating part, with some good old-fashioned math, and a bit of relativity thrown in to add to the fun.Say you could only see one GPS satellite signal. Knowing the speed of light, and presumptuously presuming that your clock is exactly in sync with the satellite, you can figure out how long the signal took to reach you and an incredibly rough location. Since you know the satellite's location, and how long the signal took to get to you, you can plot out a large circle. Your elevation plays a part, but we'll ignore that for simplicity. You now know that you could be anywhere on this circle, which isn't altogether that useful on its own. But your sat nav can see more than four satellites at any one time. Getting the same information from a different satellite gives you another circle. When you have two circles that overlap, that tells you you are in one of the two points of overlap. Adding data from a third satellite will add another circle, which will intersect with your true location. However, GPS always uses data from at least four satellites in order to account for receiver clock drift.       So where does Einstein come in? Of course, it's his theory of relativity.  "As predicted by Einstein’s theory, clocks under the force of gravity run at a slower rate than clocks viewed from a distant region experiencing weaker gravity," NASA explains. "This means that clocks on Earth observed from orbiting satellites run at a slower rate. To have the high precision needed for GPS, this effect needs to be taken into account or there will be small differences in time that would add up quickly, calculating inaccurate positions."So without Einstein or somebody else figuring out relativity in his absence, you wouldn't be able to know your precise location using GPS.All “explainer” articles are confirmed by fact checkers to be correct at time of publishing.

There is no GPS on the Moon – so to find where things land and go, we have to rely on orbital observations. To make this work easier, NASA has developed an ingenious object that doesn’t require power to make its presence known: You put it on top of your lander and you are ready to be found, then you wait for NASA’s Lunar Reconnaissance Orbiter (LRO) to shoot a laser at you. It worked for the Vikram rover, and has now worked for Smart Lander for Investigating Moon (SLIM) too.SLIM is a Japanese Aerospace Exploration Agency lander, and Vikram is a mission from the Indian Space Research Organisation. With these landers, the Asian nations became the fourth and fifth countries to land on the Moon. NASA Laser Retroreflector Arrays have hitched a ride on both of them so they can be tested out.The device on SLIM is the size of a cookie, 5 centimeters (2 inches) across. It has eight quartz corner-cube prisms set into a dome-shaped aluminum frame. Thanks to those, it can reflect light coming from multiple directions. LRO can use its laser altimeter to hit it and record the light that bounces back.“LRO’s altimeter wasn’t built for this type of application, so the chances of pinpointing a tiny retroreflector on the Moon’s surface are already low,” Xiaoli Sun, who led the team that built SLIM’s retroreflector at NASA’s Goddard Space Flight Center as part of a partnership between NASA and JAXA, said in a statement.But there was a complication: SLIM landed on its side, so it wasn’t easy to actually get a ping from the retroreflector. The first eight attempts led to nothing. It was only the ninth and tenth attempts that resulted in a signal back. It took multiple attempts for Vikram as well, but there, the team didn’t have to make sure they knew exactly where the location of the lander was. To confirm the signal was from SLIM, that was necessary.Still, it shows that the system works – even in unexpected conditions. A future system of positioning involving the retroreflectors would have an orbital partner actually designed to do such a job. LRO’s altimeter is not bespoke. So the fact that the system works even at an angle is great.  “For the LRO team to have reached a retroreflector that faces sideways, instead of the sky, shows that these little devices are incredibly resilient,” Sun added.The system could be used in future crewed and uncrewed missions to land closer to other spacecraft or objects already on the surface of the Moon.

The “unsinkable ship” known as the Titanic became arguably the most infamous shipwreck in history in 1912 after it struck an iceberg. After warnings were ignored, it wasn’t until a lookout spotted the iceberg that evasive action was taken, but it was too late.The ship’s starboard side was punctured, allowing five of 16 compartments to flood with water – one more than the ship was equipped to handle – but could things have been different if no action had been taken? Would the Titanic have sunk if it hit the iceberg head-on?             The Titanic’s Break-UpOne of the accolades that earned the Titanic its “unsinkable” status was the inclusion of 16 compartments in the hull that were believed to be watertight. Even if flooded, it was thought that the ship could remain functional if no more than four of them filled with water. Unfortunately, when the Titanic struck the iceberg, it seems water got into five of them.This has often been quoted as the leading cause of the Titanic sinking, though a review marking the 100th Anniversary in 2012 concluded that identifying a single cause is complex. That’s because several things went wrong after the collision, like buckling of the ship's bottom and failure of the joints due to stress.Avoiding The IcebergThere are several reports of other boats at sea trying to warn the Titanic of ice up ahead, but it seems that these were ignored as ice wasn’t considered a significant threat to massive ships. That meant that by the time lookout Frederick Fleet spotted the massive iceberg directly ahead, efforts to steer around it failed to avoid a collision and the starboard side was hit and the hull buckled, allowing water to rush into the compartments.As five of the compartments were breached, the ship took on water, sinking the bow and causing the stern to rise into the air. Eventually, the ship snapped in two and the bow was fully submerged, meanwhile, air trapped in the stern saw it become vertically raised before sinking into the depths.  Hitting The Iceberg Head OnThe SS Arizona was a 450-foot long ship that in 1879 hit an iceberg stem-on and sailed to tell the tale for another 50 years. Another ship, the SS Grampian, also survived a head-on collision in 1919. The two vessels by no means came out unscathed, both taking on serious damage and the SS Grampian lost two stewards, but the ships themselves didn’t sink.So, had the Titanic taken the damage head-on rather than down its starboard side, could it too have stayed afloat? According to the YouTube channel Oceanliner Designs, the complex honeycomb structure of steel in the ship’s stern means it theoretically could’ve had enough elasticity to suffer the blow without instantly breaking apart.The folding in that occurs when a ship hits a stationary object head-on like this is called telescoping, and in history, it’s happened to numerous ships without them sinking. Certainly, the view that Titanic could’ve stayed afloat with a head-on collision is one that was shared by Edward Wilding, deputy to Thomas Andrews in the ship’s design department.Excerpt from the British Wreck Commissioner’s Inquiry, Day 19The Commissioner: Do you mean to say that if this ship had driven on to the iceberg stem on she would have been saved? Edward Wilding: I am quite sure she would, My Lord. I am afraid she would have killed every firemen down in the firemen's quarters, but I feel sure the ship would have come in. C: And the passengers would not have been lost? EW: The passengers would have come in. […] C: Do you think that if the helm had not been starboarded there would have been a chance of the ship being saved? EW: I believe the ship would have been saved, and I am strengthened in that belief by the case which your Lordship will remember where one large North Atlantic steamer, some 34 years ago, did go stem on into an iceberg and did come into port, and she was going fast.Mr. Laing: The "Arizona" - I remember it.  According to Wilding’s testimony, the Titanic would have crumpled, killing many workers in the affected part of the ship as it was crushed 24 to 30 meters (80 to 100 feet) into the bows, but she could have stayed afloat. Of course, to expect the ship’s captain to make such a call in the face of an oncoming iceberg the size of a city block wouldn't be reasonable, but it raises interesting ideas about the design of such enormous vessels.Furthermore, coming to an abrupt stop when ramming into the side of an enormous iceberg comes with its own fatal consequences. As the 100th-anniversary review concluded, it’s difficult to know what could have been given the complexity of the ship’s design and how the ship could have responded to such an impact, and the possible outcome of a head-on collision becomes even more murky when you take into account the fire theory.

For 30 years, physicists have been considering the possibility of creating a unique propulsion system called a warp drive. But this is not an engine in the usual sense of the word. This hypothetical device could compress space-time in front of a spacecraft and thus allow it to fly at superluminal speeds. This may sound like science fiction, but physicists believe that warp engines could theoretically exist and someone would use them to move through space. These could be potential highly developed aliens. The authors of a study published in the Open Journal of Astrophysics presented a way to detect such an engine in space. Warp drive is theorized to create a warp bubble around the spacecraft. Actually, the ship itself is not moving anywhere, but the bubble is moving, thanks to the compression of space-time in front of the ship. This allows you to achieve speeds that are faster than the speed of light. In theory, warp drive requires exotic matter and negative energy to operate. Opponents of this idea believe that such an engine cannot exist, because it violates the known laws of physics. On the other hand, even if it is possible to create a warp engine, it is unclear how to control it and deactivate the warp bubble upon reaching its destination. The authors of the new study believe that, in theory, warp engines could exist and are already being used, and the consequences of stopping their operation could be detected. Physicists believe warp drive should release gravitational waves, or ripples, into the fabric of space-time that produce black hole or neutron star mergers. Photo: space.com That is, this hypothetical device itself can be detected. Physicists created simulations that revealed the possible effects of warp drives on spacetime. Physicists believe that warp drive should release gravitational waves, or ripples, into the fabric of space-time that produce black hole or neutron star mergers. These waves can be detected by gravitational wave detectors on Earth, but more sensitive instruments need to be developed. Physicists say that the necessary technologies already exist. Thus, the receipt of a unique gravitational signal will indicate that warp engines really exist. Simulations have shown that when a warp drive stops or slows down, a wave of negative energy is released, followed in turn by waves of positive and negative energy. This process leads to an increase in overall energy and could be further evidence of the operation of warp drive, since the energy waves will interact with ordinary matter. So far, humanity does not have the necessary technologies even for fast manned flights to the farthest corners of the solar system, not to mention reaching the nearest stars. Even at the speed of light, it would take a spacecraft at least 4 years to reach the closest triple system, Alpha Centauri. By the way, as Focus already wrote , scientists have options for quick travel to this star system. Therefore, for interstellar travel it is necessary to create technologies that could allow spaceships to fly at superluminal speeds. In this case, the flight to the nearest stars will take months, not years. But all this still remains only theoretical reflections of physicists or the basis for the creation of plots by science fiction writers. Will warp drive ever be created? There is no exact answer. Does it even exist somewhere in space? Maybe. The post Scientists will see if aliens use warp engines to move through Universe appeared first on Anomalien.com.
