How Is Radiation Chemistry Different From Other Types Of Radiation?

How Is Radiation Chemistry Different From Other Types Of Radiation?Chemistry, especially in its nature as a science, has always been a fascinating field. All around the world, chemists are busy studying and experimenting with different kinds of chemicals, using various techniques and procedures. Chemists are continuously searching for new ways to improve their understanding of the causes of reactions, methods of production and various processes and the contribution of each of these when it comes to getting out of physical conditions and producing a more superior product.Chemistry, or its scientific fields, are always affected by the changes and development that occur in the areas of modern technology. In this way, the role of chemistry is also affected by the rapid advances in science and technology. Scientists work continuously and on an international scale to develop new drugs, medicines and other types of chemicals. The quantity of products developed from this can only be describe d as astounding, yet each new product leaves the chemist with the same question - 'Is this really working? '.Many, though they do not have enough knowledge, try their hand at chemistry and in the process take great risks. It can lead to a lot of money loss and even life threatening diseases if used incorrectly. In such cases, it is advisable to hire professionals who are adept in the use of radioactive substances and techniques.The two main types of radiation chemistry are the ionizing and the non-ionizing. It is easy to understand that the non-ionizing type of radiation chemistry is concerned with electrons and atoms. The ionizing type of radiation chemistry deals with particles that have a high level of negative charge.Ionizing radiation chemistry is the one that uses lead for example. There are a few precautions that need to be observed while handling such materials for this type of radiation chemistry.The most important precaution that needs to be followed when handling radioact ive materials is to ensure that there is no physical contact with the surface. For this, plastic sheets should be used. This will allow the metals to not absorb any of the radiation. It is therefore important to make sure that the surface is smooth so that no fine particles can escape.After this, the materials used in radiation chemistry should be kept clean. Any dirt or contamination should be cleaned up immediately, before any radiation is released into the air. The material must also be sealed and protected from leaks and damaged.

3 Amazing Stories of Language Learners Who Changed the World

3 Amazing Stories of Language Learners Who Changed the World 3 Amazing Stories of Language Learners Who Changed the World Some people say that it takes some secret talent to learn languages.But would they say that about someone who can sing, play an instrument and keep rhythm?Using a language is really just a skill like any other, and as long as you’re interested in that skill and you keep practicing, youll see amazing results.Ever since I started being interested in languages, Ive loved reading stories about people who have been able to dedicate their lives to the same passion.Some people have gotten really good at learning languages.Really  good.These people generally dont just learn languagesâ€"they live them.And to me, the stories of amazing polyglots from the pre-internet age are the most impressive of all.Just think of the discipline it took to learn a language without the convenience of online courses and videos!Learning about people who accomplished so much linguistically in less-than-ideal circumstances can be both inspirational and instructive: It can help increase your motivation to learn l anguages as well as understand how you might structure your life and time in order to do it.So below are the stories of three great language loversâ€"otherwise ordinary people who overcame lifes challenges to achieve incredible success in the fields of languages and linguistics.And all without a single app to play with.For me personally, these are stories of people who I look up to.If I can act like they acted and apply myself to my languages with the same dedication that they did, I know I can go far.And the same goes for you! How to Be a Language Lover: Key Lessons to ApplyWhen you read the stories below, think about the problems that these polyglots faced and imagine what they might have been thinking.However they might have reacted to individual challenges, they all kept their optimism and confidence that they could use their skills to succeed.They came from different corners of the world and experienced vastly different things throughout their lives.Yet their minds were alway s open, always looking for more opportunities to learn or expand their knowledge. If there was any unanswered question about languages or linguistics, they always had an ear open for the solution. Just like how if you have a question about a word or a phrase in your target language, you can feed that curiosity: look it up, ask native speakers, keep that question alive and challenge yourself to find the answer.Finally, these folks all stayed with their languages for their whole lives. They didnt treat them as a passing fad or something to acquire quickly and then ignore. They knew that learning a language is a process that never truly ends, no matter how your life may change.3 Amazing Stories of Language Learners Who Changed the WorldYuen Ren ChaoY.R. Chao was born in 1892 in Tianjin, northern China.From a young age, he moved around a lot with his family, and learned to  speak and understand different dialects of Chinese, including Changshu and Mandarinâ€"which differ as much as Engl ish and German do!Not long before the fall of the Qing Dynasty  in 1912, he went to America for the first time to study at Cornell University. There, he formally studied mathematics and physics while also staying interested in linguistics and corresponding with linguists in China.He had already achieved fluency in English before leaving China, and by the time of his graduation, he could speak French and German, and read Greek and Latin.At that time, the new Chinese government was beginning to agree on a standard for the official national language, and in the 1920s, he recorded several sets of phonograph records designed as models of the Mandarin language.After that project, he performed an extensive study of Chinese dialects in several different provinces.He learned enough of the local dialect wherever he went so that the locals wouldnt have to speak Mandarin with him.He was apparently able to pick up some dialects in just two months, thanks to his extremely refined ear for phonetic s.He eventually returned permanently to the U.S. and became a citizen, but not before interpreting Bertrand Russells philosophy lectures into Chinese and writing widely-used textbooks for Mandarin and Cantonese.In the U.S., he taught Chinese to university students and applied his own personal method for learning languages: focus on the spoken language first, and read aloud as much as possible.Later on in the twentieth century, other researchers would confirm that reading aloud in a foreign language does, in fact, have serious benefits to the learner.The modern-day language enthusiast can take away two main ideas from Y.R. Chaos story:Develop your ear through phonetics knowledge or ear training exercises.Dont be afraid to read your homework aloud.He had to deal with early recording technology for his dialect studies, but digital technology has made it a snap to record yourself and check your accent in an instant.As long as youre pronouncing things correctly, youre building important pathways in your brain by associating your speech with the image of the word on the page as well as the sounds coming out of your mouth.FluentU can help you get started on applying this principle right away. FluentU takes real-world videosâ€"like movie trailers, music videos, news and inspiring talksâ€"and turns them into personalized language lessons. Youll always have pronunciations, example sentences and authentic context right at your fingertips, and youll be able to stay interested no matter what kind of content you like, a subject thats relevant to our next language loverKató LombKató Lomb was born at an exciting time. It was 1909 in Budapest, and the world that she grew up in was on the brink of irreversible change.After obtaining her PhD in chemistry, she saw that the economic depression was making job prospects dire for those in the scientific fields. So she decided to teach English.She just had to learn it first.In her language learning, Kató plunged into reading cheap yet thrilling romance novels, armed only with a dictionary and unbridled enthusiasm.Her strategy was soundâ€"if the story is exciting enough, it can keep you going past what you dont understand. Eventually, you can pick up what you need through context.These principles took her further than she could have imagined.After the end of the Second World War, she began a long and successful career of interpretation and translation.In fact, she was one of the first professional simultaneous interpreters in the worldâ€"simultaneous interpretation is a job arguably significantly more challenging than translation or consecutive interpreting as all the work happens in real time.Not stopping at English, she acquired French, Russian, Polish, Chinese, Japanese and quite a few other languages that she used to work as a translator.Kató believed that enthusiasm was the most important part of language learning. Accent and grammar could always come later if you were simply thrilled about learning and understanding new words in the language.No matter what language she was speaking, she always had faith in herself to complete her assignment along with the energy to keep studying her whole life.Heres how you can apply Katós techniques and attitude to your own language learning:You too can develop a pure enthusiasm for learning and learn to be okay with not knowing everything at first.Set aside some time for extensive reading and lose yourself in the world of a new book. The momentum from the story will carry you through the confusion of the vocabulary. And if youre bored by the story, toss it aside and move on. Life is too short to push yourself through boring books!Ken HaleKen Hale was born in 1934 and grew up in the rugged American Southwest. As a boy, he kept his ears open for as many foreign languages as he could.He picked up Spanish, Navajo, Tohono Oodham, Hopi and more from his friends and roommates at boarding school. In fact, he got in trouble at school for focusing more o n languages than homework.Later on, he gained fame and respect for publishing a truly staggering amount of research on many  Australian aboriginal languages.Even more  fascinating, he became so fluent in one, Warlpiri, that he raised his two sons speaking it.Ken was always extremely sensitive to the needs and wants of the local language communities. He established schools of linguistics and language revitalization programs across the world so that native speakers could lead their own communities in reviving their languages.All his life, even during his long tenure teaching at Massachusetts Institute of Technology (MIT), he had a legendary ability to learn languages quickly and accurately.If you want to take some lessons away from Kens methods, you can learn like a field linguist. The skills they develop for learning obscure unwritten languages work just as well for any language, no matter how many people speak or write it.Here are some ideas to try:Seek out a dedicated native speake r tutor who can coach you on pronunciation first and review whatever notes youre taking.Learn the sound system first, because youll want to hear every detail of what your tutor saysâ€"plus, that way, you can take more accurate notes.Ken started out this way. Then hed move quickly on to sentence patterns.If you learn how to say I am walking to the river, its probably not far off from I am running to the river or I am walking to the forest. It takes a lot of patience to check your guesses with a tutor, but patience was a virtue that Ken had in spades.To him, speaking to somebody in their own language was a mark of respect. If only we could all be so respectful!These three polyglots have sadly all passed away by now, but between them, theyve left us a treasure trove of writings and recordings to remember them by.Each of them left a permanent mark on their fieldâ€"Yuen Ren Chao on Chinese pedagogy and dialect studies, Kató Lomb on interpretation and translation and Ken Hale on endanger ed language preservation.And though each of them was capable of prodigious feats of memory or analysis, their most important shared trait was passion.What will you do with your love of languages?

15 Top Female Scientists Who Have Changed the World

15 Top Female Scientists Who Have Changed the World Today I want to talk about female scientists (in no particular order) who have changed the world with their research. These fabulous female scientists made a mark on the world of science and forever changed the way we look at the world. Katherine Freese is a trailblazing modern scientist who studies dark matter, including studying “dark stars” in the universe, something that has never been observed directly by a human. She’s the Director of Nordita, an institute for theoretical physics in Stockholm. Barbara McClintock won the Nobel Prize in 1983 for her studies of the genetic makeup of corn, and specifically, her discovery of jumping genes, or the ability of genes to change position on the chromosome. Gertrude Elion, another Nobel winner, was a biochemist and pharmacologist who developed drugs to treat leukemia and prevent kidney transplant rejection. Rosalind Franklin was a British biophysicist known for revolutionary work discovering DNA, as well as understanding X-rays and molecular structure. Henrietta Swan Leavitt was an American astronomer who discovered the relation between the luminosity and the period of Cepheid variable stars. The Milky Way is about 100,000 light-years in size, a key figure that would have never been discovered without her findings. Ada Lovelace was the first computer programmer in the world. Ada penned her research on the analytical engine, the mechanical general purpose computer of Charles Babbage. Her observations on this engine was acknowledged as the first algorithm. The programming language developed by US Department of Defence is named after her. Sau Lan Wu, a Chinese particle physicist, who warmed up her theatrical career by discovering charm quarks and gluons, and then really changed the entire course of scientific history by helping to discover the Higgs boson, the so-called God Particle. Jane Goodall is the most famous primate scientist in history. Jane Goodall was renowned for her work with chimpanzees and as a champion of animal rights. And Goodall wasn’t just working in a lab; she climbed trees and mimicked the behavior of chimps in Tanzania to gain their trust and study them in their natural habitat. Vera Rubin, an American astronomer, proved that dark matter existed in the universe by concluding that invisible gravity sources were pulling planets and stars in certain directions. Jennifer Doudna is a professor of chemistry and molecular cell biology at the University of California, Berkeley. She is a creator of the gene editing technology, CRISPR. CRISPR could allow us to cure diseases and take control of evolution. Maria Goeppert Mayer, a German immigrant to the US who studied at Johns Hopkins during the Great Depression. Her most famous contribution to modern physics is discovering the nuclear shell of the atomic nucleus, for which she won the Nobel Prize in 1963. Marie Stopes, the British scientist, is best known for her achievements in the fields of birth control and sex education in the 20th century. Her book Married Love broke many barriers in the society. Marie Curie, Polish/French scientist. Madame Curie was the first woman to receive the Nobel Prize and the first person to win the Nobel Prize for two separate categories. Her first award was for research into radioactivity (Physics, 1903). Her second Nobel prize was for Chemistry in 1911. A few years later she also helped develop the first X-ray machines. Sara Seager has discovered 715 planets with the Kepler Space Telescope, a remarkable contributor to the modern understanding of space. Ruby Sakae was an American biochemist and bacteriologist. She made major contributions to the development of vaccines to fight polio. Do you want to become a scientist? Tutors on TutorZ want to make science more accessible to students, inspire them.
