Why do we do this? Why do we want to know? Why do we care?” Castilloadame said. Students talk over each other and with each other and - exceptionally - seem less interested in their iPhones. Whiteboards roll and projector screens move up and down. “Do either of these approaches speak to you?” she asks the students. She lays out two options on the whiteboard to answer one particularly tricky question. In Nowicki’s classroom, for example, almost every exercise starts with a prompt like “talk to your group mates” and ends with “explain yourself.” Educators say that colleges aren’t following Common Core, but acknowledge that current math reforms in both higher education and K-12 are based on research showing that students can thrive in “engaging” learning environments. The changes at San Diego State and in other colleges’ math classes are similar to components of the Common Core Standards for Mathematical Practice - the movement driving change at the K-12 level in the 40-plus states that have adopted it - which also place an emphasis on asking students to communicate their reasoning and construct arguments. The smaller sessions would be required and would correlate to material taught in the lectures. They did away with an online version of precalculus, extended class hours and established a learning center and “learning communities” to offer support for students who typically struggle in math and science classes.ĥ0 percent of students don’t pass college algebra with a grade of C or above, according to a recent report from the Mathematical Association of America.Īnd, like some of their peers at other universities, they introduced a major change in their approach: Students would continue to attend lectures, but now they would also attend smaller sessions wired for student-centered active learning, in which the focus would be on concept-based discussion - not just absorbing information. That December they formed a calculus task force. In 2014, the newly elected O’Sullivan, along with frustrated faculty, decided to overhaul the program. Nowicki waits about a minute and says, “You can’t be wrong.”Ī few years ago, administrators at San Diego State noticed high “D-F-W” (grades D and F, and withdraw) rates - 35 to 50 percent - for math courses, according to Michael O’Sullivan, chair of the math and statistics department.

Beneath his bat-like wings, he carries the corpses of criminals. His mammoth body can be found twisting through the roots of Yggdrasil, especially around Niflheimr, the cold world from which all the rivers of Midgard spring. Occasionally, he might slither into Hel to visit the dark goddess who some people consider his master.īalance is extremely important in Norse mythology, and while Nidhogg does represent a ghastly force, he is still important to supporting the balance of Yggdrasil. A great eagle, who represents wisdom and virtue, perches in the uppermost branches of the tree, while Nidhogg, representing chaos and evil, lurks in its roots. The constant tension between the eagle and the dragon is fueled by Ratatoskr, a squirrel who runs up and down the tree ferrying insults between the two enemies. This tension may seem undesirable, but it actually promotes a cycle of growth in the tree of life. After the eagle and the dragon spend the day destroying Yggdrasil in their frenzy to attack each other, the tree is bathed in water from the wells of Urd, which promotes healing and new growth. In addition to bringing balance to Yggdrasil, the monster also figures in the punishment of criminals. He rules over the dark shores of Nadastrond, to which the corpses of murderers, adulterers, and oath-breakers are banished. A terrifying hall, with walls woven from serpents and a ceiling that drips venom, waits for these criminals, and inside the hall, the dragon chews on their bodies.įinally, the dreaded dragon has a role to play in Ragnarok, the day when the giants will attack the gods and destroy most of their world. Ragnarok will begin when the dragon finally manages to chew through the roots of Yggdrasil, causing the tree to yellow and the worlds it supports to plunge into a three-year winter. At the end of this frigid and chaotic period, he will fly up from the underworld, carrying dead criminals and leading the giants on an attack against the gods. Ultimately, the he will survive this battle and become the force of evil which balances good in the post-Ragnarok world.Yggdrasil is a giant mythical tree that serves as the center of the Norse cosmology in Norse mythology. It is an immense ash tree that is said to connect the nine worlds of Norse cosmology. Each of these nine worlds is inhabited by various beings, including gods, humans, and elves. Yggdrasil was the immense ash tree that connected and supported the world in Norse mythology Yggdrasil did not have a creator The roots of Yggdrasil extend into the underworld, and the branches of the tree reach up into the heavens. Yggdrasil’s origins in the Norse mythological poems are not properly explained however, by reading the Norse creation story, we know that the sacred waters of Mimir, Urd, and Hvergelmir were among the first locations to be created out of the dead giant Ymir. It is possible that the seed that would become Yggdrasil obtained it’s nourishment from these waters and began to grow into the World Tree of the Norse. Throughout the majority of Norse mythological sources Yggdrasil has been described as an ash tree, and not an oak or a yew. The Norse deeply venerated the ash tree, and even believed the gods created the first man, Ask, out of an ash tree and gave it divine spirit. The many uses of ash wood, such as in spears, bows or building material, created a deep appreciation for it, which over time led to it being considered a sacred tree.

What Is New in CommuniGate Pro Updates?. The Panda pencil stock is probably sufficient to fuel America's appetite for lead for many years to come. You might be able to find some of the sizes Panda made - but you won't find any made in the USA. Cheap imports, combined with domestic environmental restrictions, have wiped out the American mechanical pencil lead industry in its entirety. None of these leads are made in the United States anymore. The earliest leads appear to date to the late 1920s the latest, from 1989, 036" leads, boxed in 1,000 gross cases in numerous hardnesses and colors as well as box after box of leads made in unusual sizes and compositions. That afternoon, Veley purchased everything Panda had left - standard sized. It didn't take any convincing for him to make the trip that Saturday, and it didn't take long when he arrived to see how important Panda's stock was to anyone interested in vintage mechanical pencils. With just a week left before all the company's stock would wind up in the dumpster, her internet search for people who might be interested in vintage mechanical pencil lead brought her straight to Jonathan Veley, who has written several books on the subject of mechanical pencils, was publishing a daily blog on antique pencils called The Leadhead's Pencil Blog, and who by coincidence lived in Newark, Ohio, only about two hours away. Since the building had to be cleaned out when the keys were turned over, the daughter of Panda's president began searching for someone to buy what was left. Inside were several decades' worth of unsold inventory and leftovers. Panda wasn't able to afford the required upgrades, so the company discontinued the manufacture of mechanical pencil leads, focusing instead on wood advertising pencils.īy late 2013, Panda's leadmaking machinery had been sold for scrap, and in November, the owners sold the building. As needle-thin leads became fashionable in the 1980s, imported Japanese leads with a new polymer-based composition were much cheaper to make, once the initial equipment investments were made. Panda manufactured leads from traditional blends of clay and graphite. In addition, many smaller pencil companies which offered their own brands of lead were probably also selling Panda lead. You may well have never heard of the company, because the products it made were supplied in bulk to many of America's large mechanical pencil manufacturers, including Dur-O-Lite, Autopoint, Eversharp and Eberhard Faber. The Panda Pencil Company, located in Trenton, Ohio near Cincinnati, was one of the major manufacturers of pencil leads in the United States through the latter part of the Twentieth Century. When she discovers some of her missing uncle’s notes, she decides she’s going to take the scientific community by storm and make a name for herself (along with the help of her scientist husband) by creating life - a life no human alive has ever seen and one that won’t be able to be ignored. It features Frankenstein’s great niece, Mary, an ambitious and budding scientist/paleontologist who wants to be taken seriously and contribute in a greater way to the scientific community but is looked down on - mostly for being a woman. Whether you were a fan of the classic Frankenstein or not, this is a fantastic Fall read to add to your list. Read it if you want: a Gothic and inventive re-imagining of Frankenstein It’s bananas & over-the-top but the perfect kind of Fall read if you re-watch all your favorite slasher flicks during spooky season. When some unsettling incidents start happening at night, she wonders if it’s a coincidence or if the angered author is stalking her. She reads a horror novel that she think is truly awful and leaves a 1 star review for it on Amazon - a review that upsets the author who tries to make her take it down and eventually threatens her after their back and forth. It’s about a woman who is house-sitting an isolated coastal house in Washington off season, wanting to get away for personal reasons, and one of the things she does in her quiet life is read a lot of books. Listen, this is a great fall read thanks to the amount of psychological suspense as well as the rainy, isolated Washington State coastal setting that adds to the spook factor.

Other names for CH3F include Freon 41, HFC-41, and Halocarbon-41. The vapor pressure of the fluoromethane gas is 3.3 MPa. The gas has a pleasant odor and at high concentrations, the smell is similar to ether. The molecular geometry of the molecule is tetrahedral, that is, sp3 hybridization. Methyl fluoride is the member with the lowest mass in the HFC series.ĬH3F is a liquefiable, flammable gas with a molecular weight of 37.015 g/mol. HFCs are related to CFCs(Chlorofluorocarbons) but do not cause any damage to the ozone layer as they do not give rise to reactive chlorine. Fluoromethane, as the name suggests, is a haloalkane (as a halide atom, fluoride, in this case, is bonded to the carbon atom in an alkane).įluoromethane belongs to the HFC(Hydro Fluoro Carbons) family and hence is a harmless greenhouse gas. As Oxygen is more electronegative, it tries to pull the bonded pair of electrons to its side and hence increase the negative charge on the Oxygen atom.CH3F or methyl fluoride is also known as fluoromethane is a non-toxic compressed gas. This leads to the dipole moment between the atoms, and there is an imbalance of the charges in the molecule, which makes it polar. This difference in the electronegativities of both these atoms causes partial negative charges on the Oxygen atom and partial positive charges on Carbon and Hydrogen atoms. Here carbon atom is the least electronegative atom, and Oxygen has a higher electronegativity. The polarity of any given compound depends on factors such as the electronegativity of the atoms in the compound, molecular geometry, and valence electrons of the compound. Keep reading to find out if CH 2 O is polar or non-polar. Now that we know quite a lot about Formaldehyde’s shape and molecular geometry, you would be wondering what its polarity is. Thus, CH 2 O is trigonal planar in shape with sp2 hybridization. This arrangement, molecular geometry, and bond angles result in the formation of a trigonal planar shape. Carbon is in the central position of the plane formed by the three electron clouds, and atoms are at the corners of the triangle. And as the central atom has no lone pair of electrons, the bonded pair of electrons are evenly spread, and every atom has a bond angle of 120 degrees with the central atom. CH 2 O Bond angleĪccording to the VSEPR model, the electron clouds need to be as far as possible to avoid repulsive forces. And according to VSEPR theory, it has an AX3 formula and sp2 hybridization. As there are three electron regions around the central atom, the carbon atom’s steric number is 3. The non-bonding pair of electrons on the Oxygen atom is spread out evenly to reduce the repulsive forces between these lone pairs of electrons. As the central atom shares all its valence electrons with Hydrogen and Oxygen atoms in the molecule, its octet is complete. Here as one can notice, the Carbon atom is in the center and forms bonds with three atoms ( two Hydrogen atoms and one oxygen atom ). It becomes easy to study the molecular geometry of any compound once we know the Lewis structure and its hybridization. Also, it has an sp2 hybridization that will help us determine the compound’s molecular geometry with ease. There are no lone pairs of electrons on the central atom, while there are two lone pairs on the Oxygen atom. In the Lewis structure of Formaldehyde, the central Carbon atom has single bonds with two hydrogen atoms and a double bond with the Oxygen atom. To understand the molecular geometry, shape, and polarity of CH 2 O, let us first quickly go through its Lewis Structure and hybridization. Creating Your Calendar It integrates natively with G-Suite.

See this glossy ceramic picket wall-tile set at Home Depot You can easily combine these patterns with materials, sizes, and colors until you settle on the designs you want to have for your backsplash. The different layout options can affect the style and vibe that your backsplash will provide. The great thing about picket tiles is that their unique aesthetics transcends time and different styles, which is the main cause of their growing popularity.Īnd when it comes to tile layout, there are three different options you can consider, including horizontal, vertical, and braided (or diagonal) patterns. When dealing with timeless and classic picket tiles, you can get as creative as you want. See this picket tile backsplash set at Amazon But they can also be used to create an accent wall that boldly stands out. These classic and timeless, slim types of backsplash tiles can easily imitate the subtle and elegant look of picket fences. And if you want to use the clean and sleek look of a picket fence on your walls or backsplash, this material will definitely help. Picket fence tiles are perfect for homeowners who are into geometric shapes and modern styles. With inspiration rooted in classic hexagon tiles, picket fence tiles are named as such because of their elongated shape that you will usually see in the picket fences of peaceful urban homes. Picket fence tiles are home materials that deliver both classic and modern aesthetics to your home. With picket fence tiles though, you can definitely build a stunning kitchen backsplash for your home. Picket is a word that you would usually associate with fences but it’s not common for it to be associated with walls. What Design Style Does This Backsplash Belong To?.You’ll find all the information and measurements you need in each frame’s product description. But they can always be removed if you’d rather not use them. Picture mounts are included with a lot of the frames we sell. And this makes it easier for you to find a frame that fits, since you can frame smaller pictures in larger frames. It’s used both for decoration and to prevent your photo from touching the glass.Ī picture mount is particularly striking when framing small prints in large picture frames. It’s a piece of paper or cardboard that sits between your picture and the glass of the frame. Adjust the frame size with a picture mountĪ picture mount is like a secondary frame, inside the frame. You can also go for a much larger one and add a picture mount to play around with the perspective. Get the size as close as possible for a nice, tight frame. When choosing a frame, the number one priority is that the frame is larger than the picture you want it to hold. Here’s a size guide, measured in centimetres: For example, A3 is two times larger than A4, and A4 is two times larger than A5, and so on. Every time the number decreases, the paper doubles in size. Paper is measured in metric ‘A sizes’, most commonly ranging from A9 (smallest) to A0 (largest). Understanding paper sizes is necessary when you want to frame your favourite print or photo. For example, a black picture frame goes very well on a bright wall, while a white or silver frame does a good job of making your picture pop on a darker surface. A tip is to use contrasting colours to accentuate and bring attention to your picture. Make sure to choose the colour and style of the frame based on where you want to use it. This can contribute as much to the décor as the picture it displays. Others are fixed in size but are more ornately designed to compensate. Some frames are more basic and are available in sizes from A6 (10.5 cm x 14.8 cm) all the way to A1 (59.4 cm x 84.1 cm). IKEA sells an array of different frame styles, shapes and colours. Either way, a nice frame will help highlight, contrast or tie your pictures in with the rest of your interior design. Display some photographs of treasured memories from past adventures. Celebrate friends and family by adding their pictures to your wall. Frames offer a great way to make the people and places you love a natural part of your room.
