His missing feathers are a symptom of stress and show that he had a hard life before finding a safe place with his new foster family. Griffi is a rescue bird that was taken home by a foster family from the Florida Parrot Rescue. The sweet little bird danced his heart out, shaking what few tail feathers he has left. In a video that was released in October 2020, Griffi the cockatoo can be seen getting down to “The Humpty Dance” by Digital Underground. There have been many viral videos of parrots dancing to music and making their owners laugh. His research also suggested that dancing is a response to joy and happy feelings in the brain. Aniruddh Patel, a researcher from the Neurosciences Institute in San Diego, California, discovered that when parrots dance they are not simply mimicking human behavior – they are actually feeling and responding to the rhythm of the music. It is a little-known fact that parrots love to dance.

While we appreciate the sleek design, sometimes our iPads need a little help when it comes to durability. Nothing ruins the relaxation or productivity of an iPad quite like a bashed corner, smashed screen, or scratch right above your camera lens. What a shame because I LOVE there form factor.We may earn revenue from the products available on this page and participate in affiliate programs. If you want to replace your laptop with iPad, the Magic Keyboard makes it 95% capable, but if you want a tablet experience to complement your laptop as well as a super slim lightweight package the Smart Keyboard folio can’t be beat.Įdit: went to two Apple stores in NYC and all 6 iPad minis I looked at have awful jelly scrolling. Ultimately my almost 3 year experiment of replacing my MacBook with iPad has been successful, but the 5-10% of the time I need a Mac it really does hurt to be limited by iPadOS. I think that the size is still slightly too big for my home couch device, but I think I’ll wait for the mini to get refreshed with a better display or an amazing deal before giving this iPad up. When I want a cursor I can use the Magic Mouse or just grab a laptop. I’m happy now to be able to flip the keyboard back and use it as a tablet. The Magic Keyboard practically doubled the weight of the iPad Pro. The reduced weight made me realize that this thing is super portable still and I really don’t need a mini to get the desired portability I want. Now over the past week I’ve switched back to the Smart Keyboard folio and I gotta say, this thing really makes the iPad a tablet again. I went ahead and sold my Magic Keyboard to a friend in anticipation of getting a new mini and trading in my 2018 11” iPad Pro, but after the initial reviews and the jelly scrolling issues I’ve decided to hold off for a bit. I was becoming frustrated with the limitations of iPadOS and wanted to switch back to a MacBook for a while. When the iPad mini 6 was announced I was pretty hyped for that form factor and a better “couch device” to complement my iPhone mini. I had the Magic Keyboard on my iPad for over a year now and I had my Smart Keyboard folio tucked away in a drawer during that time. I got the 2018 iPad Pro when Apple didn’t refresh the 12” MacBook to replace my aging 11” MacBook Air. I was super excited for official cursor support on iPadOS and immediately purchased the Magic Keyboard. Thank you for reporting spam and other rule-breaking content.

Midgard was considered the most vulnerable of all the realms, continuously threatened by the giants from Jotunheim. The gods fashioned Midgard as a place for humans to live and separated it from the remainder of the universe by an ocean and an impassable barrier called the Midgard Serpent. Midgard, located in the center of the Norse cosmos, was the realm designated for human habitation and surrounded by the realms of the gods (Asgard) and the giants (Jotunheim). Midgard: The Human World Runestone dedicated to a Viking mother, via the National Museum of Denmark, Copenhagen These humans received life from the gods and were placed on Midgard to live. Furthermore, the Norse creation myth included the fashioning of the first humans, Ask and Embla, from two trees by the deities. Thus, Niflheim and Muspelheim were the antagonistic forces that engendered the cosmos. The gods Odin, Vili, and Ve subsequently put an end to Ymir and used his corporeal remains to forge the realms. Muspelheim’s fiery heat melted the icy terrain of Niflheim, initiating the emergence of life, which took the form of the entity Ymir. It was a place of blazing heat and radiant light, serving as the source of all the fire in the Norse cosmos.Īccording to Norse mythology, the convergence of Niflheim and Muspelheim marked the genesis of the universe. Conversely, Muspelheim was a realm of fire, also existing before the universe’s creation, and represented an antithesis to Niflheim. This world was associated with obscurity, low temperatures, and demise, and was considered the origin of all the rivers and streams that flowed throughout the Norse universe. Niflheim was regarded as a primeval realm characterized by frigid mist and ice, predating the universe’s inception. In Norse mythology, Niflheim and Muspelheim were two prominent realms that played a pivotal role in the genesis of the cosmos. Muspelheim and Niflheim: The Primeval Realms of Fire and Ice in Norse Cosmology Odin and his Brothers Create the World by Lorenz Frølich, Unknown, via Wikimedia Commons Additionally, the Norse cosmological tradition includes the prophesied event known as Ragnarök, which foretells the end of the world. The creation narrative describes how the universe was formed through the interplay between these two opposing forces. The universe’s origin story centers around the primal entity of Niflheim and Muspelheim. The nine worlds were Asgard, Midgard, Jotunheim, Niflheim, Muscenters, Helheim, Alfheim, Svartalfheim, and Vanaheim. In Norse mythology, the structure of the universe is organized into nine distinct realms that are interconnected by the ash tree Yggdrasil. Despite its destructive nature, marking the demise of many gods and the world itself, it leads to the rebirth of a renewed universe and a new pantheon of gods.
The best way to find these options is to look them up using a search engine. The Premier and Enterprise versions aren’t prominently displayed on the QuickBooks sale options page. The Enterprise version is for the biggest companies ― among small businesses ― and includes several advanced pricing, inventory tracking, and costing features that are geared toward manufacturers with complex needs. The Premier version includes various inventory and transactions features and is especially good for companies who are dedicated to using desktops for their accounting. If you’re interested in this version, you might find one of QuickBooks’ online versions more useful due to having more feature options and a cheaper price. The Desktop Pro Plus version is advertised alongside the online versions but its features appear lacking amid a transition to a primarily cloud-based accounting service. QuickBooks desktop versions get yearly updates with incremental updates and minor tweaks to their layout designs. Its products are also often offered at a discount from their original prices. Intuit has been investing heavily into its online versions with frequent updates. QuickBooks online versions also have added functions that allow businesses to accept payments, manage, and pay bills, and payroll functions. However, QuickBooks has since expanded to offer cloud-based, online-only versions that are compatible across several platforms, including PC, Mac, smartphones, and tablets. The popular brand has been around for nearly three decades and began as a desktop-installed software program.

How we testedįor this article, I drew upon my own experience wearing and selling gas masks, which helped make the practical application parts of this article easier, but acknowledged my own lack of expertise on the matter, and instead turned to CBRNE experts in the military and DoD civilian communities who have, in some cases, relied upon their respirators to save their lives while they work with hazardous chemicals and substances. Remember, when buying used, and at least once a year, check the seals of your gas mask to prevent contaminant infiltration. The advantage here is that there are ways that you can actually own the same gas masks trusted by military CBRNE specialists, and we’re here to show you these ways, and offer some important tips on how to make sure that the next time there’s some sort of airborne contaminant, you’re set. These hazards are nothing new, and people have taken to purchasing subpar (but heavily advertised) gas masks as a way to remediate this. The western United States experiences wildfires and high levels of airborne smoke, which can aggravate respiratory illnesses, and during the BLM protests in 2020, many people realized that the clouds of CS gas used by the police affected everyone, even if they weren’t physically at the protest. service members have realized that gas masks aren’t just for suffering through yearly gas mask qualifications, but are useful tools for any sort of situation where airborne chemicals or particulates are present.

Mosquito bites commonly cause itchy red bumps, which can vary in size from being very small to 1/2 inch.Don’t forget small items like pet bowls, vases, and flower pots. Make sure to empty containers that can collect water at least once a week. Mosquitoes can lay thousands of eggs in very small amounts of water. You can also help lower the number of mosquitos in your area by removing sources of standing water. Wear long sleeves and pants outdoors if you can.Īvoid areas where there are lots of mosquitoes, if possible. Use EPA-approved insect repellent that repels mosquitoes.Ĭover up as much skin as possible when you're outdoors. So the best option is to avoid getting bit in the first place. Pus, oozing, or other drainage from the biteĭealing with mosquito bites isn’t fun. Red streaking that moves away from the bite toward your heart Worsening redness, tenderness, or pain of your mosquito bite If you have signs of a skin infection, you should see a healthcare provider right away. These breaks let bacteria get into the skin and cause infections, like cellulitis or impetigo. When should I see a doctor about my mosquito bite?Īvoiding infection is the most important reason to resist the urge to scratch mosquito bites. You can try loratadine ( Claritin) or diphenhydramine (Benadryl) - just make sure to follow directions for dosing. Make sure you stop using it after a few days to avoid side effects like skin discoloration.Īntihistamines: OTC antihistamine medications can also relieve mosquito bite itching. Over-the-counter (OTC) 1% hydrocortisone cream is a great option. Steroid cream: You can try anti-itch cream for mosquito bites to help relieve itching. You can reapply the paste for worsening itchiness as you need it. Apply your paste of choice to your bite for 10 minutes and then wash it off. Or mix oatmeal bath products with water to form a paste. Mix 1 tablespoon of baking soda with enough water to create a paste. Applying ice directly to your skin can lead to skin damage.Īnti-itch pastes: Try some DIY anti-itch pastes. Make sure to wrap the ice pack (or ice) in a towel. You can reapply whenever the itching gets worse. Apply an ice pack to your bite for about 10 minutes. Ice packs: Ice can help decrease swelling and itchiness. There are several things you can try at home to stop a mosquito bite from itching: How can you get mosquito bites to stop itching? If you develop large, painful welts after getting bit by mosquitoes, you may have this type of reaction, also called Skeeter’s syndrome. These reactions aren’t just itchy - they’re also painful and can form blisters. Other people develop very large local reactions. Some people don’t react to mosquito bites at all, while others react so severely that they develop anaphylaxis, a life-threatening allergic reaction. A larger hive is a sign that your immune system is reacting more strongly to the mosquito’s saliva. Just like with other types of allergic reactions, some people react more severely than others. So people who develop these hives are actually having an allergic reaction to mosquito bites. The itchy, red welt that’s left behind after a mosquito bite is actually an urticarial reaction, or a hive. Some people develop bigger bumps after mosquito bites. The itching will gradually disappear over 7 to 10 days. Mosquito bite itching usually starts about 20 minutes after a bite and gets worse over the next 24 to 36 hours. This signal alerts the immune system to work on getting rid of the mosquito saliva. Histamine is a signal to the rest of the immune system that there’s something in the body that shouldn’t be there. This triggers your immune system to release histamine, and a side effect of this substance is itchy skin. Why do mosquito bites itch?Ī mosquito injects saliva into your body when it bites you. Let’s take a look at why mosquito bites itch - and what you can do to stop mosquito bites from itching. While you can’t completely avoid mosquitoes, there’s still plenty you can do to relieve itchy mosquito bites. Sometimes, no matter how careful you are, you end up with multiple, itchy bites. Most people are familiar with the annoying reality of mosquito bites. I pack up all my stuff, grab my trash, and lock my car. Running to my trunk I grab my camp clothes, throw them on and set my normal clothes in the backseat. I pull up to the Whitney portal parking lot and instantly I see two women coming off the trail. I’m going to climb that! It’s a scary and exhilarating feeling all at once. The snow decorates the edges of each peak and the sun shines over the top giving a magical feel. That must be Whitney! It’s beautiful! Ok, I’m not sure if it was Whitney, but it’s close enough. The rock formations are so pretty and the stormy clouds with the sun peaking through over the mountains were creating an angelic look over the peaks. As I drive I admire the beautiful landscape. The drive up to Whitney Portal is longer than I thought it would be. Let’s do it! The worst that can happen is I don’t find a ride, I drive back to town, and go back to plan A. I’m sure there are hikers just finishing that will give me a ride. Why don’t I drive to Whitney Portal, park my car for free, and hitch a ride to town right now. I quickly check how much a shuttle will be if I don’t want to hitch. Well storing my car in Lone Pine was going to cost $75. Light bulb! My original plan was to leave my car in Lone Pine and hitch a ride after the trail back to my car. Before I knew it I was almost to Lone Pine. I listen to music, complete a Spanish lesson, call David, and listen to my book on Audible. Here we go! GPS says it will take 4-1/2 hours to get to Lone Pine. I say goodbye to the dogs, lock up the house, and pull out of the driveway. Even as I lay here getting ready to go to sleep I wonder did I forget anything? I hope not. I love them so much, and I just want to spend every minute with them. Plus it’s hard to pull myself away from the kids. Really I just didn’t want to compress my sleeping quilts too long and I didn’t want to pack my food too early. I wish I hadn’t waited to pack until today. By the time we went over everything regarding the two dogs, two cats, and eight chickens, I was an hour behind with more to do before I could head out on the road. She’s a neighbor and we talked way too long. My normal pet sitter was busy, so I have a new one this time. I’ll have to figure out how to fix that remotely.ĭavid is out of town, so I also had to meet with the pet sitter. OMG! I forgot to set my out of office email setting! Gah! My brain is fried. Nothing will make coming back to work easy, but every bit helps to make it less hard. I create moving plans, send off several emails to keep progress going and clear complete all important items on my task list. I’m heading out for three weeks, and when I get back I’m moving my office and furnishing a new model home. There’s so much I need to do on this last day of work. I head to the kitchen, brew a cup of coffee, and sit on the couch with my laptop. Yes! There is a God! The power is back on. Click! The fan starts wiring and the lights suddenly flick on. I pull myself out of bed and head to the bathroom. I guess I will have to drive to my office after all. No! I had planned on working at home to save time. I wake up just before 8 and the power is still off. I put in earplugs, but I can still hear it. I close my door, but I can still hear the chirping. “What is the chirping all about?” she asks. My smoke alarm was not happy about the power outage either. No! Not today! I have so much to do before I check out for the next three weeks. This morning I awoke to a flash of lightning, a crash of thunder, and our power going out. My story starts here as I begin to embark on an epic adventure as I resume my travels on the John Muir Trail. So pop some popcorn, grab a blanket, and get cozy. I’ve only just started and it’s already been an adventure. They always say that getting there is half the fun. Haha! Ok, not that bad, but it did take some time. I’m pretty sure I spent the same amount of time planning how to get to and from the trail as I did planning how to hike the trail. Who knew that the logistics of hiking a long trail could be so complicated. Who cares? I care of course… and maybe you since you’re reading this. Why does anyone care? Well, today is the first day of my travels to resume the John Muir Trail. Today is the day!!! Well it’s not “The Day”, but it is a day for sure. But, what happens when there’s a wall placed in the water with a small opening? Let’s take a look. If you’ve ever been to the ocean, you can imagine the waves of water rolling in. Since the wavelengths of visible light are very, very small, this phenomenon may not be very intuitive. If these two things are similar in size, then the light can be bent more. The amount that the wave bends depends on the size of the wavelength and the size of the opening, or aperture. So, the whole picture of dispersion is that the different wavelengths of light are absorbed differently by the atoms in the refractive medium, which results in slightly different indices of refraction and slightly different angles of refraction for each wavelength of light, thereby dispersing the light.ĭiffraction, on the other hand, refers to the phenomenon of waves bending as they pass through an opening or around the edge of an object. In other words, materials have a range of optical densities corresponding to different wavelengths. The amount of light absorbed by the refractive material depends on the wavelength of the light. The more optically dense a material is, the higher the index of refraction. The term used to measure the ratio of the speed of light in a vacuum, c, to the speed of light in a medium, v, is called the index of refraction: n=c/v, and it is also an indication of the optical density of a material. While light travels at about \(3 x 10^ m/s\) in a vacuum, it travels slower through any medium, depending on the optical density. The higher the optical density of a material, the slower light is able to pass through it. Refractive materials are described by their optical density, which is a measure of how much of the light gets absorbed by atoms in the material. They refract again once they leave the prism due to the differences in refractive properties between air and the prism. Shorter wavelengths (violet) get refracted more than the longer wavelengths (red). When white light hits the refracting surface, the different colors of light separate because of their differing wavelengths. Let’s take a look at each of them separately.ĭispersion occurs when light of different wavelengths, such as white light, hits a refracting surface, like a prism. Let’s get started!ĭispersion and diffraction are each descriptions of light interacting with matter in different ways, and both can be used to separate light of multiple wavelengths. Hi, and welcome to this video on the diffraction of light waves! In this video, we will compare and contrast diffraction and dispersion and take a look at how diffraction gratings work. |
