Hey! You in the corner of the library with your nose stuck in a book. Yes, you. Don’t recognize me without that awful perm, do you? (Remind me again why you thought that was a good idea?) Anyway, I hope you don’t mind if I sit with you for a minute, but we need to talk. Don’t worry about the “no talking in the library” rule. I’m sure we’ll be fine. Librarians aren’t as bad as they seem. Judging from the hair and braces I’d have to guess you’re in your junior year. Yes? Thought so. I’d forgotten how many lonely lunch hours you spent in the school library. You have some friends in the cafeteria that you could sit with, but you don’t feel like you really fit in, do you? That’s why you joined every school club you could. I just counted and you’re in eighteen, not to mention the numerous after-school activities you’re involved in. I mean honestly, you joined the ROTC.1 You don’t even like ROTC! And I won’t even bother bringing up that time you tried ballet. I’m still having nightmares about the fifth position! Let me ask you, how’s it all working out? Not very well, am I right? By spending so much time trying to find yourself, you’re slowly losing yourself. We don’t all have one single rock-star talent, and honestly, I think those of us who don’t are the lucky ones. Life isn’t about finding the one thing you’re good at and never doing anything else; it’s about exploring yourself and finding out who you really are on your own terms and in your own way. You don’t have to exhaust yourself to do that. Oh, don’t be so down in the dumps about it. You’ll eventually find something you’re good at, I promise. It’s a long, winding road to get there, but you’ll find it. Being able to spend all day doing what you love (or one of the things that you love) is the most amazing feeling in the world. And no, I won’t tell you what it is, so don’t even ask me. Just remember to always be yourself, because there’s nobody else who can do it for you. I think E. E. Cummings put it best when he said, “It takes courage to grow up and become who you really are.” Looks like the bell is about to ring so I’ll leave you to your book. What are you reading, anyway? Oh, The Last Battle by C. S. Lewis. I should have guessed. You should give those Harry Potter books a try. I saw you roll your eyes! I know they seem like just another fad, but trust me, they’re better than you think. They’ve got a real future! finding out who you really are on your own terms and in your own way.

The following days are a jumble of gunfire, digging, gobbled food, soldiers running in and out of the forest in small groups, distant explosions, stray shells, bandaged heads and unexpected lulls. On the very first day, before dawn, I am ordered into one of the newly dug trenches. I huddle there, squeezing my magic buttons and singing songs to the dog. When the fighting stops, the dog disappears, but a new companion takes his place. A strange little soldier crawls along the trench toward me. ‘Private Sasha!’ he cries. ‘I’ve been looking for you all day long!’ He’s old, like a grandfather, a dedushka. He has a black patch over one eye, a tape measure around his neck and a row of pins threaded into his sleeve. Hanging from his belt is the most enormous pair of scissors I have ever seen and I wonder if he uses them as a weapon. He doesn’t tell me his name, so in my head he becomes Dedushka. Dedushka squats, cups his hand to his ear, peers over the top of the trench and smiles. ‘It’s safe to be upright . . . for now.’ He helps me to my feet, dusts me off and commands me to stand as tall and straight as I can. Then he measures me. Everything from head to toe – even my toes! He writes numbers in a little notebook, strings his tape measure back around his neck, salutes and hurries away. It’s all very strange, and I wonder if Dedushka has been bumped on the head during the battle and is now a little bit muddled. I should have given him a hug before he left. I chase after him but stop when I’m hit by a shovelful of flying dirt. Sleepy Bear is digging a cave! ‘Are you going to hibernate?’ I ask. Sleepy Bear chuckles. ‘No, although that would be wonderful! I could do with a lo-o-o-ong sleep.’ He sighs and closes his eyes. He doesn’t open them again and I realise that he has gone to sleep. Standing up! I shake his arm, and he opens his eyes and keeps talking. ‘No, I’m not hibernating. I’m digging a little nook where I can sleep and eat. I’ll hang up my raincape as a door that can open and close so it feels just like a real home . . . except for the lice . . . and the bad smells . . . and the bombs that make the walls shake and crumble.’ He points further along the trench to where other soldiers are digging. ‘We’re all making little houses in the ground.’ ‘Like rabbits and moles,’ I say. Sleepy Bear chuckles. ‘Yes! And soldiers who need to hide from German bullets and bombs.’ He stops digging to roll a cigarette. ‘Should I be making a house?’ I ask. ‘I want to hide from German bullets and bombs, too.’ Sleepy Bear flops to the ground, lights his cigarette, closes his eyes and takes a deep puff. I wait for him to answer, but, instead, he begins to snore! I poke him in the side. He snorts and he murmurs, ‘I think someone has already built you a house, Sasha. Keep going along this beautiful village street and you are sure to find it.’ He falls asleep once more. I kiss his dusty cheek and whisper, ‘Thank you, Sleepy Bear.’ A little way along, I see Cook in a cloud of smoke. He has lit a fire, right here in the middle of the trench, and is stirring a cauldron full of kasha. He squats as he stirs. ‘What are you doing?’ I ask. ‘Cooking supper, of course!’ he cries. ‘But why are you doing it here?’ Cook points his spoon at the ground above the trenches. ‘Because if I do it up there, my pot will be filled with holes from German bullets and all of the kasha will leak out onto the ground. It’s bad enough that our supplies can’t get through German lines and there’s nothing to cook but buckwheat for kasha. But if we lost the kasha, too . . .’ ‘Hungry soldiers,’ I say. Cook nods. ‘And grumpy!’ ‘Like Boris!’ I gasp. ‘Even worse,’ warns Cook. I picture the kasha pot full of bullet holes. And then I realise that if the kasha pot were full of holes, then Cook would be, too. I wrap my arms around Cook’s neck and say, ‘I think this is a very good place for cooking our supper.’ I kiss his smoky cheek and run along. At the end of the trench, I find the biggest hole of all. It’s wide and deep and as busy as a beehive in a blossom tree. Above, a group of soldiers is rolling logs into place for a roof, while below, typewriters rattle and pencils scratch and papers flutter and voices crackle out of five different radios. Their words tangle together to tell a strange wartime fairy tale about German guns and a loving father called Stalin and a Red Army regiment that is lost in the deep, dark forest and a wicked beast called Hitler and a delivery of vegetables that was hit by a bomb and blown into a million tiny pieces too small even to make soup. In the middle of it all, wrestling with a rumpled map, his rifle still slung over his shoulder, is Major Scruff. ‘Major Scruff!’ I run and jump into his arms. ‘Is this our new home?’ ‘Yes, Sasha. I suppose it is.’ ‘Is it safe from German bullets and bombs?’ I ask. He stares at me. ‘Were you scared in the trenches today, Sasha?’ ‘No,’ I reply. ‘I had magic buttons and a dog and some songs to sing. Were you scared in the forest, Major Scruff?’ ‘Yes,’ he says. ‘Poor Major Scruff!’ I press my hand against his cheek. The dark, rough stubble is grubby with grit and his eyelids are taking a long time to open after every blink. ‘You need a shave and a nap!’ I scold. He chuckles. ‘I am too tired to shave and too busy to nap.’ I scrunch my nose while I consider his problem. ‘I know!’ I cry. ‘You nap and I will shave your whiskers. That will be two jobs tumbled into one!’ And so that’s what we do. Major Scruff slumps into a chair and snoozes while I lather his face with soapy water and shave his whiskers. The soap suds travel from his face, up into his hair and down the front of his uniform, and I have to shave his jaw and chin three times because I keep missing bits, but I finally get it all done. I am just wiping his cheeks dry when the dog appears. He licks my hand, then stretches up and licks soap suds from Major Scruff’s ear. Major Scruff wakes with a start. He feels his newly shaved face and cries, ‘Wonderful, Sasha! I feel smooth, clean, rested and ready for action.’ He ruffles my hair. ‘We must do this again tomorrow. Although next time, you might wake me with a gentle shake of the shoulder instead of licking my ear.’

Wizard and Cat 71: Losing the Race (단어) (W all)

By the late 1800s, the Spanish were losing control of Cuba. Concerned about insurrection in the countryside, they moved rural Cubans to “reconcentration” camps where the Spanish claimed they would be better able to protect them. U.S. Consul-General Fitzhugh Lee forwarded the following account of the conditions of the camps to the U.S. Assistant Secretary of State on November 27, 1897. Lee said the author of the note was “a man of integrity and character.” “[W]e will relate to you what we saw with our own eyes: “Four hundred and sixty women and children thrown on the ground, heaped pellet-mell as animals, some in a dying condition, others sick and others dead. . . . “There is still alive the only living witness, a young girl of 18 years, whom we found seemingly lifeless on the ground; on her right-hand side was the body of a young mother, cold and rigid, but with her young child still alive clinging to her dead body; on her left-hand side was also the corpse of a dead woman holding her son in a dead embrace. . . . “The circumstances are the following: complete accumulation of bodies dead and alive, so that it was impossible to take one step without walking over them; the greatest want of cleanliness, want of light, air, and water; the food lacking in quality and quantity what was necessary to sustain life. . . . From all this we deduct that the number of deaths among the reconcentrados has amounted to 77 per cent.” Source: Unsigned note that was included in a telegram sent by Fitzhugh Lee, U.S. Consul-General in Cuba, to the U.S. Assistant Secretary of State November 27, 1897. consul-general: a government official living in a foreign country charged with overseeing the protection of U.S. citizens and promoting trade pell-mell: state of disorder accumulation: pile want: lack reconcentrados: the reconcentration camp prisoners; The following is an excerpt from Albert J. Beveridge’s speech, delivered September 16, 1898. Beveridge gave this speech while he was campaigning to become a senator for Indiana. The speech helped him win the election and made him one of the leading advocates of American expansion. “Fellow citizens, it is a noble land that God has given us; a land that can feed and clothe the world;. . . . It is a mighty people that he has planted on this soil . . . It is a glorious history our God has bestowed upon his chosen people; . . .a history of soldiers who carried the flag across the blazing deserts and through the ranks of hostile mountains, even to the gates of sunset. . . . “The Opposition tells us that we ought not to govern a people without their consent. I answer: The rule of liberty that all just government derives its authority from the consent of the governed, applies only to those who are capable of self-government. I answer, We govern the Indians without their consent, we govern our territories without their consent, we govern our children without their consent. “They ask us how we will govern these new possessions. I answer: If England can govern foreign lands, so can America. If Germany can govern foreign lands, so can America. . . . “What does all this mean for every one of us? It means opportunity for all the glorious young manhood of the republic, the most virile, ambitious, impatient, militant manhood the world has ever seen. It means that the resources and the commerce of these immensely rich dominions will be increased. . . . “In Cuba, alone, there are 15,000,000 acres of forest unacquainted with the axe. There are exhaustless mines of iron. . . . There are millions of acres yet unexplored. . . . It means new employment and better wages for every laboring man in the Union. . . .

WHAT DOES THE WORLD GAIN WHEN WE PROTECT TIGERS? Tigers are one of the world’s most recognized animals. Throughout history they can be seen in cultural traditions across Asia, as well as in brand images and logos the world over. But while they might be omnipresent across our cultural landscape, their actual existence in the wild has been dramatically reduced to only a few pockets of their historical range. Wild tigers are now found in just 10 countries, their historical range shrunk by over 95%.er / WWF-US If tigers completely disappeared, we’d be losing so much more than an iconic species… Protecting water sources for millions of people Tiger habitats overlap nine of Asia’s most important watersheds which supply water to more than 800 million people. Protecting these tiger forests is the most cost-effective way to prevent droughts, reduce flooding, and limit the impacts of climate change. Protected Areas are proven to reduce deforestation and across Asia tigers are the driving force behind creating and effectively managing protected areas. For example, India recently declared its 51st Tiger Reserve, Srivilliputhur Megamalai, in southern India and this new protected area will safeguard more than 1,000km2 of key river habitat. Lose tigers, and lose entire forests Here in Cambodia, where I photographed the country’s last wild tiger in November 2007, tiger spirits were used by indigenous communities to help regulate the management of forests and wildlife. Harvesting of valuable plants was only permitted in certain times of the year and only after the tiger spirits had been appeased. Failure to adhere would result in wild tigers stalking you in the forest. However, with the extinction of the tiger the spirits have vanished, and the forests become an open free-for-all.aysia / Lau Ching Fong Protecting tigers also protects a multitude of other species Tiger-protected areas save much of Asia’s amazing wildlife. Take, for example, India’s Manas Tiger Reserve in Assam where tiger populations are increasing. In addition to tigers the grasslands and forests of Manas Tiger Reserve support the only viable global population of the world’s smallest, and rarest pig –pygmy hog – and, my personal favorite, the Bengal florican. This critically endangered gamebird, which I studied for my doctorate, finds a mate with an elaborate display involving males shooting themselves into the sky before plummeting down kicking their legs as if riding a bicycle. Without tigers, these and many more species would not be as well protected. A cultural and spiritual icon for millions There are plenty of examples of mythical animals, such as the unicorn, and extinct creatures, like the dodo and dinosaurs, which remain part of international consciousness. Tigers are a global phenomenon, but unless conservation is successful, they will only be known in zoos or in cultural media. A world without tigers would be economically and spiritually a much poorer place. Let us continue focusing our efforts towards doubling wild tigers and ensuring that this species does not become a vanished cultural icon.

Understanding the Features of Finance: A Guide for Newbies Finance is a broad field that involves managing money, including activities such as investing, borrowing, lending, budgeting, saving, and forecasting. As a beginner, understanding the basic features of finance is crucial. This guide will relate these features to blockchain technology, cryptocurrency, and decentralized finance (DeFi). 1. Basic Financial Concepts Investing: Putting money into assets like stocks, bonds, or real estate with the expectation of earning a return. In the blockchain world, this translates to investing in cryptocurrencies like Bitcoin, Ethereum, or various DeFi projects. Borrowing and Lending: Traditional finance involves banks and financial institutions providing loans. In the DeFi space, platforms like Aave and Compound allow users to borrow and lend cryptocurrencies without intermediaries. Budgeting: Planning how to allocate your income to cover expenses, save, and invest. Using blockchain technology, you can utilize smart contracts to automate budgeting and savings processes. 2. Blockchain Technology Blockchain is a decentralized ledger that records transactions across multiple computers. It is the technology behind cryptocurrencies and has several key features: Transparency: All transactions are recorded on a public ledger, making them visible to anyone. Security: Cryptographic techniques ensure that data on the blockchain is secure and tamper-proof. Decentralization: No single entity controls the blockchain, reducing the risk of centralized control and failure. 3. Cryptocurrencies Cryptocurrencies are digital or virtual currencies that use cryptography for security. They operate on blockchain technology and offer several advantages: Lower Transaction Costs: Sending money across borders is cheaper with cryptocurrencies compared to traditional banking methods. Accessibility: Anyone with an internet connection can access cryptocurrencies, promoting financial inclusion. Ownership and Control: Users have complete control over their funds without relying on banks. 4. Decentralized Finance (DeFi) DeFi is a movement that uses blockchain technology to recreate and improve traditional financial systems in a decentralized manner. Key features of DeFi include: Smart Contracts: Self-executing contracts with the terms directly written into code, enabling trustless and automated transactions. Liquidity Pools: Users can provide their assets to a pool and earn interest or rewards, promoting liquidity in the DeFi ecosystem. Yield Farming: A strategy where users move their assets between different DeFi platforms to maximize returns. 5. Applications in DeFi and Blockchain HaloFi Save: A platform that leverages blockchain technology to help people save money efficiently and securely. It encourages users to save larger amounts for longer durations, offering higher interest rates compared to traditional banks. Non-Custodial Savings: Users have full control over their funds, reducing the risk of losing their money to institutional failures or fraud. Access to DeFi: Integrating with DeFi platforms like Moola Market, HaloFi Save provides additional opportunities to earn interest on savings, promoting financial growth and stability. Practical Example: A Farmer's Journey Imagine a farmer in a remote village in Africa. Traditionally, this farmer might not have access to banking services, making it difficult to save money, get loans, or invest in better farming equipment. With platforms like HaloFi Save, the farmer can: Save money securely and earn interest. Access microloans through DeFi platforms integrated with Celo. Participate in educational programs to learn more about blockchain and DeFi. Conclusion Blockchain technology, through platforms like HaloFi Save and initiatives by Celo Africa DAO, has the potential to drive significant social change by promoting financial inclusion, transparency, and access to resources. By empowering individuals and communities with the tools and knowledge to participate in the digital economy, blockchain can help address global issues and foster sustainable development.

Ions Ions are charged substances that have formed through the gain or loss of electrons. Cations form from the loss of electrons and have a positive charge while anions form through the gain of electrons and have a negative charge. Cation Formation Cations are the positive ions formed by the loss of one or more electrons. The most commonly formed cations of the representative elements are those that involve the loss of all of the valence electrons. Consider the alkali metal sodium (Na) . It has one valence electron in the n=3 energy level. Upon losing that electron, the sodiu ion now has an octet of electrons from the second energy level and a charge of 1+ . The electron arrangement of the sodium ion is now the same as that of the noble gas neon. Consider a similar process with magnesium and aluminum. In this case, the magnesium atom loses its two valence electrons in order to achieve the same arrangement as the noble gas neon and a charge of 2+ . The aluminum atom loses its three valence electrons to have the same electron arrangement as neon and a charge of 3+ . For representative elements under typical conditions, three electrons is usually the maximum number that will be los. Representative elements will not lose electrons beyond their valence because they would have to "break" the octet of the previous energy level which provides stability to the ion. Anions Anions are the negative ions formed from the gain of one or more electrons. When nonmetal atoms gain elections, they often do so until their outermost principal energy level achieves an octet. For fluorine, which has an electron arrangement of (2, 7), it only needs to gain one electron to have the same electron arrangement as neon. Forming an octet (eight electrons in the outer shell) provides stability to the atom. Fluorine will gain one electron and have a charge of 1− . The electron arrangement of the fluoride ion (2, 8) will also change to reflect the gain of an electron. Oxygen has an electron arrangement of (2, 6) and needs to gain two electrons to fill the n=2 energy level and achieve an octet of electrons in the outermost shell. The oxide ion will have a charge of 2− as a result of gaining two electrons. Under typical conditions, three electrons is the maximum that will be gained in the formation of anions. Subatomic Particles in an Ion Since ions form from the gain or loss of electrons, we can also look at the number of subatomic particles (protons, neutrons, and electrons) found in an ion. Remember that the number of protons determines the identity of the element and will not change in a chemical process. Example 2.5.1 How many protons, neutrons, and electrons in a single oxide (O2−) ion? Solution Oxygen has the atomic number 8 so both the atom and the ion will have 8 protons. The average atomic mass of oxygen is 16. Therefore, there will be 8 neutrons (atomic mass−atomic number=neutrons) . A neutral oxygen atom would have 8 electrons. However, the anion has gained two electrons so O2− has 10 electrons. We can also use information about the subatomic particles to determine the identity of an ion. Example 2.5.2 An ion with a 2+ charge has 18 electrons. Determine the identity of the ion. Solution If an ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium. Polyatomic Ions A polyatomic ion is an ion composed of two or more atoms that have a charge as a group (poly = many). The ammonium ion (see figure below) consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH+4 . The hydroxide ion (see figure below) contains one hydrogen atom and one oxygen atom with an overall charge of 1− . The carbonate ion (see figure below) consists of one carbon atom and three oxygen atoms and carries an overall charge of 2− . The formula of the carbonate ion is CO2−3 . The atoms of a polyatomic ion are tightly bonded together and so the entire ion behaves as a single unit. The figures below show several examples. Soult Screenshot 2-2-1.png Figure 2.5.1 : The ammonium ion (NH+4) is a nitrogen atom (blue) bonded to four hydrogen atoms (white). Soult Screenshot 2-2-2.png Figure 2.5.2 : The hydroxide ion (OH−) is an oxygen atom (red) bonded to a hydrogen atom. Soult Screenshot 2-2-3.png Figure 2.5.3 : The carbonate ion (CO2−3) is a carbon atom (black) bonded to three oxygen atoms. The table below lists a number of polyatomic ions by name and by structure. The heading for each column indicates the charge on the polyatomic ions in that group. Note that the vast majority of the ions listed are anions - there are very few polyatomic cations. 1− 2− 3− 1+ Table 2.5.1 : Common Polyatomic Ions acetate, CH3COO− carbonate, CO2−3 arsenate, AsO3−3 ammonium, NH+4 bromate, BrO−3 chromate, CrO2−4 phosphite, PO3−3 chlorate, ClO−3 dichromate, Cr2O2−7 phosphate, PO3−4 chlorite, ClO−2 hydrogen phosphate, HPO2−4 cyanide, CN− oxalate, C2O2−4 dihydrogen phosphate, H2PO−4 peroxide, O2−2 hydrogen carbonate, HCO−3 silicate, SiO2−3 hydrogen sulfate, HSO−4 sulfate, SO2−4 hydrogen sulfide, HS− sulfite, SO2−3 hydroxide, OH− hypochlorite, ClO− nitrate, NO−3 nitrite, NO−2 perchlorate, ClO−4 permanganate, MnO−4 The vast majority of polyatomic ions are anions, many of which end in -ate or -ite. Notice that in some cases such as nitrate (NO−3) and nitrite (NO−2) , there are multiple anions that consist of the same two elements. In these cases, the difference between the ions is the number of oxygen atoms present, while the overall charge is the same. As a class, these are called oxyanions. When there are two oxyanions for a particular element, the one with the greater number of oxygen atoms gets the -ate suffix, while the one with the fewer number of oxygen atoms gets the -ite suffix. The four oxyanions of chlorine are shown below, which also includes the use of the prefixes hypo- and per-. ClO− , hypochlorite ClO−2 , chlorite ClO−3 , chlorate ClO−4 , perchlorate Not your usual ion Soult Screenshot 2-2-4.png "Drink you milk. It's good for your bones." We're told this from early childhood, and with good reason. Milk contains a good supply of calcium, part of the structure of bone. However, there are two other ionic components of hydroxyapatite, the mineral component. Phosphate ion and hydroxide ion make up the remainder of the inorganic material in bone. News You Can Use Bone is a very complex structure. It is composed of protein (mainly collagen), hydroxyapatite (a calcium-phosphate-hydroxide mixture), some other minerals, and contains 10 - 20% water. The calcium/phosphate ratios are not stoichiometric, but vary somewhat from one portion of bone to the next. Bones are very strong but will break under enough stress. Regular exercise and proper nutrition help to increase bone strength. Watch a video about bone structure at http://www.youtube.com/watch?v=d9owEvYdouk Nitrate is an anion with a complex bonding structure. Major sources for this ion in drinking water are runoff from fertilizer, septic tank leakage, sewage, and natural deposits. High concentrations of nitrates represent a significant health hazard, especially to infants. The nitrate in the body is converted to nitrite, which then binds to hemoglobin. This binding decreases the ability of hemoglobin to transport oxygen, thus depriving the cells of the O2 needed for proper functioning. Cyanide production is widespread throughout nature. Forest fires will produce significant amounts of cyanide. Many plants contain cyanide, and it is produced by a number of bacteria, algae, and fungi. Cyanide is used industrially in metal finishing, iron and steel mills, and in organic synthesis processes. This material is also an important component for the refining of precious metals. Formation of a complex between cyanide and gold allows extraction of this metal from a mixture.
