Chemistry - Seventh Edition

Chemistry - Seventh EditionMolecular biology, in the seventh edition of 'Chemistry the Molecular Nature of Matter' is an updated and revised text on chemistry. This textbook examines both chemical and biological chemistry as part of its presentation. Chemistry is among the oldest sciences that has been popular for over 5 centuries and the seventh edition includes some important advances that have developed in this subject in recent years.It provides information on chemical structure and its components, as well as its reactions. The seventh edition makes a strong and significant effort to increase the current students' comprehension of all the atoms and molecules of chemistry. Another key advance is its implementation of concepts from micro- and nanotechnology. This adds a new perspective to the traditional concepts of the subject.Although the seventh edition of Chemistry the Molecular Nature of Matter makes a strong attempt to give thorough coverage to the subject, there are still ma ny topics that need to be discussed. Topics include inorganic and organic chemistry, spectroscopy, stable isotopes, quantum and lattice structures, fluorine and isotope bonding, catalysis, hydrodynamics, gas laws, atomic, molecular and nuclear physics, and atomic-based methods. The book also has sections dealing with thermodynamics, electronic structure and bonding, energy levels, the various elements, carbon, aromatic compounds, organic chemistry, non-chemical processes, as well as light and chemical reaction.There are also sections for introductory courses in molecular biology, biochemistry, organic chemistry, biotechnology, biochemistry, thermodynamics, biophysics, and systems chemistry. Students will learn about the different types of compounds, and how they are produced and destroyed, by way of various chemical processes such as combustion, abiotic oxidation, nuclear reactions, chemical synthesis, and a number of industrial processes.This edition includes numerous illustrations in the form of photographs, diagrams, illustrations, charts, computer-generated images, and pictures of molecular structures. There are also sections on molecular biology, and other topics like biochemical networks, and photolysis. They also cover some pre-standard, as well as a number of selected advanced chemistry concepts and models.The seventh edition covers all of the topics that have already been covered in previous editions. A number of additional topics are added in the chapter 'Introduction to Molecular Biology' and some new topics were introduced in the next edition. This edition also includes a 'chapter guide,' a glossary, a reference for further information, and references to specific chemical terms. These new additions significantly expand the scope of this book.The seventh edition of 'Chemistry the Molecular Nature of Matter' is suitable for students in any academic discipline, including undergraduates, graduate students, and professionals who wish to understand chemi stry. This book has a wide readership, both within and outside the chemistry community. This edition therefore is a good option for those students who are looking for a book to enhance their learning about chemistry.

4 Wise Lessons from Four Seriously Good Language Learners

4 Wise Lessons from Four Seriously Good Language Learners 4 Wise  Lessons from Four Seriously Good  Language Learners Weve got your back.If youre looking for motivation and encouragement in language learning, other language learners are your best bet, no doubt.Weve all shared tips and tricks with our classmates, harried our tutors with questions, and mined online language communities for new resources and techniques.But if you  really want to jumpstart your studies and reach your goals,  theres one group of people whose advice  you  cant afford  to miss:  the very best language learners!I’m talking about the masters, the ones who innovated or made history with their techniques and drive. Past and present have provided us with a host of big names in language learning, although you may not have heard of them yet.The best teacher is one whos been down the path before, one who devised a better way of doing things.Without further ado, here are four  ground-breaking lessons from four  champion language learners!4 Wise  Lessons from Four Seriously Good  Language Learners 1. Don’t let age hold you back .Kató Lomb: Hungarian translator, simultaneous interpreter, polyglotLomb is one of those polyglots everyone should know about. She was a pretty intense lady with a crazy life. She knew 16 languages at various levels by the time she died, and she was always curious about more. And she lived a long life, tooâ€"94 years!She certainly wasn’t one of those people who insist that adults are hopeless at picking up languages. Sure, she started her languages young, but she kept gathering more and more throughout her entire life. In her late 40s, she walked into an advanced university Polish class (she wasnt an enrolled student) and boldly told the professor she had no experience with Polish and she certainly didn’t have the prerequisites. The professor allowed her to sit in on the class, and Polish became a language in which Lomb was quite proficient.In her 80s, Lomb chatted  with Dr. Stephen Krashen (a professor at the University of Southern California who created the famed “input hyp othesis”), which he chronicled in his article here. Krashen was then in his 50s, and Lomb envied his youth, saying, “So many more languages to learn!”How  to apply this lesson:Remember it’s never too late to start learning a new language. Life is long, and theres enough time for all of your projects and pursuits! Be like Kató Lomb and just dive right inâ€"no matter your age.Try doing one small thing today to get you closer to fluency in your chosen language: study a textbook for 10 minutes, watch a TV show in your target language  or sit down with some flashcards.Adults are way better at hacking their studies than kids, so try resources that take advantage of thatâ€"like  SRS, online games  and novels in your target language (a favorite technique of Lombs).  It all adds up!2. Be creative with your learning methods.Khatzumoto:  Author of the blog “All Japanese All The Time”Here’s a more modern example for you. On his blog, Khatzumoto wrote about how he achieved fluency in Japanese in 18 months, all without living in Japan. He then chronicled his Mandarin and Cantonese learning processes as he navigated Chinese media and newer learning methods.That’s all very impressive, but here’s where Khatzumoto should really inspire you: He wasn’t happy with how Westerners presented and learned East Asian languages. Sure, he had a lifelong admiration of Japanese and Chinese, but the standing rhetoric was, and is, that those languages are impossible for Westernersâ€"that the writing systems take a decade to learn  and  foreigners would never achieve native-sounding tones.Hearing talk like that can get discouraging!But Khatzumoto examined the traditional learning techniques for Japaneseâ€"namely, textbooks, language tapes and rote memorization for kanji  and hanziâ€"and decided to abandon those methods in search of a better way of doing things.He lifted the methods from Antimoon,  a website that shares the techniques of a couple of Polish guys who learned English by watching TV, reading and playing video games:  immersion. He studied Dr. Krashen’s input hypothesis, which advocates that with enough exposure to the language, retention of vocab and grammar becomes much more natural.He discovered Dr. James Heisig’s book Remembering the Kanji,  which uses  mnemonic devices to efficiently teach all 2,042 everyday-use kanji. He combined and tweaked these as needed, and used sentences in his SRS to pick up grammar and vocabulary organically.And he achieved his goal! He reached fluency!How  to apply this lesson:If you’re not happy with your course or textbook, critically examine your methods. Ask yourself: Do any of your resources bore you to tears? Have you made notable progress in the last couple of months using a certain resource? Keep a journal where you keep track of your progress in reading, writing, speaking and listening.Check in every month or so, and make sure youre still on track and still having fun. If something isnt workin g for youâ€"or if its plain unenjoyableâ€"toss it out. Believe me, theres plenty more you can use!Try immersion like Khatzumoto, and use apps like FluentU if you get stuck for resources. Find a conversation partner to practice with, or shift your focus from speaking to understanding à la Krashen’s input hypothesis. There’s no one way to do things, so if something isn’t working for you, try something new. Never stop experimenting!3. Don’t be afraid to look ridiculous at times.Dr. Alexander Argüelles:  Intellectual, educator, hyperpolyglotArgüelles is the intellectual’s polyglot. He focuses on reading ability, and can read books in a massive  number of different languages. But don’t think that means that he’s too reservedâ€"he advocates the technique “shadowing  whereby learners simultaneously speak the target language along with a recording to improve pronunciation and prosody.Don’t think that sounds ridiculous enough? Well, in the book Babel No More  by Michael Erard, the author examines the lives of a number of polyglots, including Argüelles. The author has the chance to meet up with Argüelles and begins to study Hindi under his tutelage.Argüelles soon has Erard shouting Hindi phrases along with a recording all while briskly walking through a public park. Sure, Erard felt embarrassed doing this, but he gained confidence in those phrases he acquired.How  to apply this lesson:Try out shadowing, or even just talking to yourself for practice. Check out this video to see Argüelles himself demonstrate the technique. First, acquire audio samples in your target language. High-quality course recordings from  Assimil, Teach Yourself  or Pimsleur  work great for this, but so do many others.While listening, and without using a transcript, repeat the sounds of each word almost simultaneously with the recording, whether you understand it or not. Try to include shadowing  in your daily sessions, even for short periods of 10 to 15 minutes.It might fe el strange  at first, but embarrassment is a feeling all language learners need  to get past in order to advance, so it’s best to get used to the feeling early on.Especially if you can’t find someone to practice with, these techniques increase your speaking confidence. You’ll be that  much more  prepared for when you do get the opportunity to speak in a real-life situation!4. Milk limited resources for all they’re worth.Giuseppe Mezzofanti: 19th  century Italian cardinal, hyperpolyglot, the MezzofantiIf you’re interested in languages and haven’t yet heard of Mezzofanti,  Id be pretty surprised.He’s famous among language enthusiasts for good reason. It was said he spoke at least 30  languages excellently, nine other languages fluently, and had basic knowledge of dozens of others. History is rife with stories of Mezzofanti’s prowess at picking up languages in short periods of time.Some of this can be chalked up to legend and hyperbole. I, however, am a believer that Me zzofanti did possess rare skillâ€"one he cultivated through dedicated study and practice. After all, in Babel No More, Erard has the privilege to read Mezzofanti’s multilingual letters and flashcards. He used flashcards just like everyone else!In other words, anyone can emulate Mezzofanti.One Mezzofanti story is especially reassuring and helpful. Mezzofanti heard prisoners’ confessions regularly, in a number of languages. If he didn’t know the language in question, Mezzofanti would ask the prisoner to say the Lord’s Prayer in the language, and Mezzofanti would tease apart this short snippet to glean basic vocabulary and grammar.After all, this particular prayer was something he knew very well and in a number of different languages. By comparing short samples of the same text, Mezzofanti turned language acquisition in something more like decoding. He started all of his languages with the Lord’s Prayer.I have my doubts that this would give Mezzofanti the ability to understan d everything prisoners were saying, but there’s no doubt in my mind that this a great way to use limited resources to gain a basic understanding of a language. Mezzofanti lived at a time when it was much more difficult to come across resources in different languages. He capitalized on what was available, since he didn’t always have the luxury to get more.How  to apply this lesson:Getting the most out of our resources is something all language learners can take advantage of. Some of us just don’t have the ability to get to a country where we can buy all the books and movies we want. Some of us have limited money for such things. But even then, we surely have more than just a short snippet of text in our target languages, so imagine what we can do with that and  a little focus!Try comparing Wikipedia pages in your target language and native language and see what words you can define. Choose a topic you already know a lot about, and get yourself comfortable with the English Wikip edia page first. Compare small sections, perhaps under similar headings. Define all the words in a paragraph, and write them down in a notebook. Examine the grammar and take a stab at what it means.  Study deeply instead of widely!Obviously, Wikipedia pages wont be an exact translation, but you can still compare word usage and match up sentences where the writers were saying similar things. Another  free resource to try this with is  news articles. Find a hot topic international news article in English, and then find an article on the  same topic  in your target language. News articles tend to be short and succinctâ€"perfect for comparing languages! Again, hunt for places where the text is likely to be similar, such as headings or near proper nouns like famous names or places. Then figure out what you can!If you want to pull a true Mezzofanti and study exact texts, its easy to find translations of popular English-language books in common languages. For example, Ive read Harry Potter in Spanish, French and Dutch, as well as in English! Im a huge fan, so I already know the books well. Comparing chapters of Harry Potter makes parsing a new language fun and easy. If you like Harry Potter, e-book translations are easy to purchase at Pottermore. Choose texts you already know well (it doesnt have to be Harry Potter!), and then dive into the translation.There are plenty of polyglots, past and present, who mastered language learning. And they  have lots  to teach us, whether it’s through their own writings or simply through how they lived.By examining these heroes of language learning, we can amp up our own studies, stay motivated and achieve the goals we’ve set!

Spoon-feeding Vs. Applied learning for kids - ALOHA Mind Math

Spoon-feeding Vs. Applied learning for kids An experienced teacher says in this article, that children learn better when left to their own methods, compared to being spoon-fed. As a parent, I would tend to agree with this wholeheartedly. As young parents, we tend to over-think and over-protect our kids, worrying about hurting them in case of anything going wrong. In reality, we might be helping students to learn more by letting them explore and learn a lot of things on their own. Here’s why: Engages attention better: A child concentrating to learn something on his own will pay much better attention to the activity, compared to just being expected to listen to a teacher or parent trying to explain something theoretically. This is one reason why systems of learning such as Montessori show a very good impact on children. Better retention:Once a subject is learnt with experimenting and analysis, it stays in memory much better. Children who learn through applied systems of learning will find it much easier to remember the fundame ntals, compared to someone who was spoon-fed all the information and hasn’t actually understood the basics. Spoon-feeding Vs. Applied learning Improves creativity: Rote learning limits students by forcing them to remember just a standard set of answers to particular questions. A system that evaluates based on application helps enhance creative thinking and will form a great foundation for higher levels of learning. Builds confidence: Introducing children to independent methods of learning is a great way to improve their confidence. This also encourages life skills such as questioning and discussion that will prove great companions for your growing kids. Teaches listening skills: With better attention comes a better aptitude for listening and comprehending information. When there is no constant stream of spoon-fed information, the child is better able to pay attention when necessary. These are just some of the reasons why we need to expose our children to processes of applied learning, and take care to not spoon-feed them however tempting the option might be. Teaching skills to children is very important â€" similar to the s aying about teaching someone to fish rather than providing them fish the one time. One great method of applied learning, along with a way to build confidence in your child would be our Math and English classes at Aloha.
