![]() ![]() With your eyes closed and hands together, both you and your partner need to focus deeply on the wish, thinking in present tense terms as though your shared wish is already happening. Hold hands with your partner and place the wishing stone between your palms, then firmly clasp hands. It’s important that both people are wishing for the same thing in the same way. Method: Before beginning, go over the instructions with your partner so both of you are on the same page during the process. Intention, as always, is so important when performing any kind of magic - even when using simple wishing stones. Two heads are better than one, right? The shared wish is meant to “double” the power of the wish by using two people’s intentions rather than one. So, now that you’ve collected your stones, how do you use them? This can be a solitary activity or you can bring a friend. ![]() It’s not entirely necessary, but it adds to the experience and makes my stones seem a little more precious. Half the fun is finding them and, again, I’m someone who needs everything to matter so when I collect them, I try to go to places that feel special to me. Or, if you wanted to make a day of it, head somewhere a little off the beaten track and hunt there. If you just want to give the stones a try, you could go searching in your neighborhood and probably find one without too much effort. Location is not a problem wishing stones can be found anywhere. I’d basically turned myself into a truffle pig for wishing stones! Even though it’s rare to find one that’s perfect for wishing, it gets easier the more you search. This gave me lots and lots of practice finding them and once I’d looked at a lot of them, that white band became quite eye-catching and I could find them quickly. This is the description I have always relied on and because I have success with these stones, I’m sticking to it.Īs soon as I learned about wishing stones, I wanted to collect as many as I could. That unique white ring makes these stones somewhat rare, but unmistakable. This band can be of any thickness, but there should only be one and it should be unbroken. The common lore on wishing stones is that they can be any size or shape, and are uniform in color except for a solid white band encircling the entire stone. Identifying and Collecting Wishing Stones After some thought, I decided on three new methods, and now I want to share these methods with you. Before I used the wishes I’d been saving, I wanted to make sure I used them to their absolute fullest potential. I’m a witch who is BIG on symbolism and making sure every move counts, so simply making a wish on a stone and then throwing the stone away would never suffice. Honestly, I was left a little disappointed. ![]() It had actually been awhile since I used one so I went online to see the different methods people had for wishing. Lately, I’ve had a few rainy days and, among other things, I turned to my wishing stones. Over the years, I’ve saved quite a few of them - my rainy day wishes. I love the idea of finding them while walking around outside and then saving them for when you need a little luck. They are helpful little things if you want to take your time with them, but also a lot of fun if you just want to throw caution to the wind and wish big. Each piece is meant to serve as a memento of quiet exploration, both physical and emotional, evoking memories of wandering peacefully along a shoreline, and prompting reflection on our biggest wishes for ourselves and those we hold close.This is why I love wishing stones. The thoughtfully-designed pieces in this collection provide the versatility of both comfort and elegance. To touch, each piece is smooth like a stone that has been tumbled by the sea for centuries, and features a shiny raised line that makes reference to wishing stones. The Wishing Stone Collection features sterling silver jewellery designs that draw inspiration from the act of beach combing, and the rocks we decide to pick up and hold onto as keepsakes. These are known to grant wishes when mediated on and tossed back into the ocean, or lovingly passed along to someone else. ![]() There is one type of rock, however, that is known with certainty to be special: wishing stones.Īccording to legend, a wishing stone is a rock with a distinct, continuous line that runs around it. What is deemed a good beach rock is subject to it’s finder it could have smooth surface, a pleasing shape, or an eye-catching colour. Sometimes, particularly along the rocky shores that are characteristic of many coastal regions in Atlantic Canada, beach combing centres around finding the “perfect” rock. Upon spotting a rare variety, you’d likely pick it up, and add it to your collection as a prized possession. When walking along the any shoreline, it’s common to look down to scan the ground for intricate shells and fragments of beach glass. ![]() 5/8/2023 0 Comments Analystreview cardworks![]() ![]() The consensus estimate for earnings of Artisan Partners has been revised 6.7% upward for the current year over the past 60 days.

5/8/2023 0 Comments Youtube video watcher![]() ![]() Have you ever heard the saying, “Your best new customers are your old customers”? In other words, retaining customers can be a powerful way to grow your business. It’s the way to develop a loyal community of fans and get more views on YouTube. If that doesn’t work, he asks his community what they’d like him to make videos about.Ĭochrane said, “An amazing thing happens when you ask people what they need and want, and then you go and make it for them - they think you read their mind!” Bottom-line: Consistently create content that solves your ideal customer’s problems or meets their needs. YouTube creator Graham Cochrane racked up 51 million YouTube views by focusing on how-to content.Ĭochrane finds video ideas in the comments of his social channels. Simply identify what your ideal customers most want to know, and then create videos that meet their needs. So how can you create compelling content that will get more views on YouTube? Well, one of the best ways is to create ‘how to’ videos : It won’t matter how many hacks or ads you use if your videos aren’t good. Now let’s jump straight into the specifics of getting more views on YouTube. ![]() Answer questions from your audience in the moment and give your viewers the ultimate viewing experience. Once you have enough experience creating videos, why not try going live and talking to your audience in real-time. Think about adding cards and captions to your video to help users navigate more effectively around your channel. If you are planning to create more than one video on a particular topic, you can create a playlist and add it to this. These things will help your audience to find your video through. Within the YouTube platform, you can upload your video, including a title, tags, and a description for your audience. Take the time here to ask whether each line sounds natural, and delete lines that don’t fit into the overall video. The devil is in the detail when it comes to making a YouTube video, so practicing will account for all the things that could go wrong when shooting.Īfter doing a few takes of each scene the magic starts – you can start editing your video to omit small mistakes or elements of scenes that don’t fit. If you are starring in the video, or just directing it, it is important to prepare and practice so that the real thing will go off without a hitch. ![]() ![]() Invest in branding to add to the background of your videos and thumbnails so that your video looks top quality. Will your video be animated, live-action, or real-time? What kind of props will you need when making your video so that your YouTube followers will stay engaged during your whole video? These questions are important to answer as they will help make your video look more professional. It should include all of the things that help give a sense of direction to your production, such as the camera setup or action/dialogue each scene requires. Make sure to create one once you’re done writing your script. Having a shot list will encourage you to think about the smaller details, like lightning direction and camera placement. Don’t create a long script if your storyboard is short as it will mean a lot of lingering on screens that will not make for a good viewing experience. If you are making an in-depth YouTube video, make sure to include terms that are specific to the industry to build trust with your viewers. If your video is a beginners guide, don’t use too many technical terms. Try to keep the language relatable and appealing to your audience. This is important as you need people to want to do something after watching the video.īased on your video plan, begin writing your video script. Think about the messaging you want to portray to your audience and plan where in the video you will include calls-to-action. Generate a storyboard outlining each scene or section of the video. Before you start making a video for YouTube you need to plan what you want to produce. ![]() 5/8/2023 0 Comments Serenity home health care![]() Our team of Licenses Professionals will educate our patients about their state of health and how to maintain their maximum level of function and dependability at home.

Her services as a nurse for the region about Orumiyeh and her missionary work into the countryside and among mountain tribes gradually won her respect and helped set an example that contributed to the slow improvement of the lot of Persian women. She was virtually a mother to her pupils, who had first to be rescued from the tradition of educational neglect and early marriage to attend the school. She sailed from Boston in March 1843 and in June landed at Orumiyeh.Īfter mastering the Syriac language Fiske laboured under severe physical and cultural difficulties to build a small day school into Urmia Seminary, a boarding school for girls that won wide repute. Influenced by Mary Lyon, she responded to a call the next year from the American Board of Commissioners for Foreign Missions for a missionary to the Nestorian Christians of Persia. In 1839 she entered Mount Holyoke Female Seminary (now Mount Holyoke College) in South Hadley, Massachusetts, and, after a year’s absence due to typhoid fever, she graduated in 1842 and was promptly appointed to the faculty. At age 17 she began teaching in district schools. She was said to have read Cotton Mather’s Magnalia Christi Americana and Timothy Dwight’s Theology by the age of eight.

![]() ![]() This is a pretty obvious statement, so we could call this the california roll theorem. TheoremĪ monotonic bounded sequence must converge. These are some of the ideas that spice up our sushi roll sequences. There are a couple of theorems connecting the ideas of boundedness and convergence for sequences. If a sequence is missing one or both of these bounds, then it's unbounded. ![]() For our sushi sequence, if it is bounded, we can make a bento box with it. If a sequence is bounded above and below, we say it's bounded. We say a sequence is bounded below if there's a value K such that all terms of the sequence are at least K. Just like a function, we say a sequence is bounded above if all terms of the sequence are less than or equal to some value M. That's why, for sequences, we use "increasing" as an abbreviation for "strictly increasing". They are about as interesting as watching water evaporate off a hot road surface in the middle of summer. We don't usually care about nondecreasing sequences. This sequence is neither increasing nor decreasing.īe Careful: Using the word "increasing" to refer to a function is ambiguous because it could mean either nondecreasing or strictly increasing. The terms of the sequence a n = (-1) n bounce back and forth between 1 and -1. It's possible for a sequence to be neither increasing nor decreasing. The sequence is decreasing because the terms get smaller as n gets larger.īe Careful: increasing and decreasing aren't opposites. The sequence a n = n is increasing because the terms get larger as n gets larger. We'll have a monotonically increasing California roll, extra wasabi on the side. If a sequence is increasing or decreasing we call it monotonic because the terms are going only one way. This is like a lop-sided sushi roll where the piece on the right is bigger than the one to its left. We say a sequence is increasing if the terms get larger as n gets larger. These meals are going to look similar to functions, so you may want to review it to see the similarities. Let's look at some of the ways the martial arts master can serve up a sequence to us. Because the sequence is just a coarse-chopped list of numbers made from a function, the sequence acts in ways similar to functions. Those discrete values would form a sequence. Imagine a Kung Fu black belt took a function and chopped through it, leaving only discrete values. For the sake of intuition, it may be helpful to graph the sequence. To determine if a sequence converges or diverges, see if the limitĮxists and is finite. ![]() You'll get up, try to wrangle it, and it'll just throw you over its head again. This is the bull that catches you and throws you over it's head using its horns. The sequence a n = (-1) n diverges because it's indecisive and can't make up its mind whether to be + 1 or -1. This is the bull that gets away from you before you can lasso it. Since the terms aren't getting closer to anything finite, we say the sequence diverges. The sequence a n = n diverges because as n approaches ∞ the terms a n approach ∞ also. Sequences can diverge for different reasons. ![]() Just like a function, if a sequence doesn't converge, we say it diverges. As n gets bigger and we move to the right on the graph, the dots get closer and closer to height 1. The dots will get closer and closer to height L as n gets bigger. If we look at a convergent sequence on a 2-D graph, it looks like a function with a horizontal asymptote. The dots are trying to get to 0 on the number line. If we look at a convergent sequence on a number line, it looks like the dots are getting closer and closer to value L. This is just like convergence for functions. In symbols, a sequence converges to L if. When the terms of a sequence approach some finite value L as n gets bigger, we say the sequence converges to L, as is lasso. The terms of the sequence approach 0 as n approaches ∞. In some of the sequences we graphed, it looked like as n got bigger the values a n approached some particular value. Let's make sure we're comfortable with limits, and let's see which sequences we can stop. Sequences are like bulls at a rodeo waiting to be lassoed, but the divergent ones can't be caught. ![]() 5/7/2023 0 Comments Nasa moon secrets![]() ![]() Scientists were convinced that organisms on the ocean floor survived off dead organic matter – the carcasses of animals, faeces and the steady fall of other organic detritus or "marine snow" drifting down from above. This is then eaten by herbivores, which in turn are eaten by carnivorous animals. Plants, algae and some marine bacteria in surface waters convert the Sun's energy into sugars which they store in their organic matter. But it was still believed that all living organisms were sustained by a food chain ultimately fueled by photosynthesis. This should make it nimbler too, allowing it to get into trenches and vents in the sea floor that have never been explored before.įor a long time, marine biologists thought that life in the hadal zone was impossible, but as deep sea submersibles began venturing into the region in the first half of the 20th Century, it became apparent life could survive there. About the size of a quad bike and weighing around 550 pounds (250kg), Orpheus is designed to be much lighter, smaller and cheaper than previous underwater vehicles. "After 12 hours, we saw it coming up in small pieces," says Shank, adding that the loss of Nereus made them rethink how they explore the deep sea. The underwater vehicle imploded some 10km (6.2 miles) down, most likely due to the immense pressure. In 2014, Orpheus' predecessor Nereus was sent down to the Kermadec Trench, which lies north-east of New Zealand. It is not the first time that Shank has tried to reach the dark depths of the hadal zone. "If it works, there is no place in the ocean where you can't go." "Orpheus is a gateway vehicle," says Tim Shank, a deep sea biologist who is leading WHOI's hadal exploration programme. This allows the robot to find its way and recognise places it has already been, but should also help it shed new light on the biodiversity of this harsh environment. Using similar visual navigation technology to Nasa's Perseverance Mars Rover, Orpheus uses highly sensitive cameras to identify rock formations, shells and other features on the ocean floor to build up three-dimensional maps dotted with landmarks (or perhaps seabedmarks). Even the language the scientists use for their missions to this region shares terms with space exploration – in recent years marine biologists have sent multiple "landers" equipped with sensors and cameras to "crash-land" on the floor of the hadal zone, where they take measurements.īut engineers from Nasa's Jet Propulsion Laboratory in Southern California are building a new autonomous underwater vehicle called Orpheus, after the ancient Greek hero who travelled to the underworld and back, to map the more inaccessible depths. It is here that Nasa scientists, in partnership with the Woods Hole Oceanographic Institution (WHOI) in Massachusetts, are attempting to explore and probe the limits of life on Earth. Yet few vehicles can survive plunging into this dark abyss. Cumulatively they account for an area of seabed equivalent to the size of Australia. ![]() Consisting of deep trenches and troughs, it extends 11km (6.8 miles) below the surface of the world's oceans. Named after Hades, the Greek god of the underworld, it is a forbidding place worthy of its name. The deepest parts of Earth's oceans are known as the hadal zone. They could even provide clues about where scientists should be searching for alien life. The hope is that the underwater discoveries they make will help to unlock some of the mysteries in outer space while also test some of the equipment and experiments needed for missions elsewhere in the Solar System.Įarth's ocean depths are surprisingly similar to some of the conditions Nasa expects to find on other worlds in our Solar System. It is a mission filled with wonder, danger and a not-insignificant risk of implosion. The US space agency is exploring the deep ocean to search for clues of what oceans on other planets could look like, and push the limits of science and technology in one of the most extreme environments on our planet. In fact, it is often claimed that we know more about the surface of Mars and the Moon than about the ocean floor on our own planet. Our oceans cover more than 70% of the Earth's surface, but over 80% of them remain unexplored. ![]() |
