Принято считать, что запасов нефти хватит на несколько десятилетий, а человечество уже прошло углеводородную стадию своей истории. Это не так. Без нефти можно обойтись в энергетике, но нельзя ее заменить в производстве полимеров, из которых сделан современный мир. Разведка и добыча углеводородов — амбициозная высокотехнологическая задача. Для ее решения используются методы геофизики, химии, математического моделирования, алгоритмы машинного обучения — и не только.

WHAT YOU DO: Use computer simulations to look at how the Earth's surface moves over time, compare this with information from satellites to better understand the earthquake cycle, and use it to create disaster response products and plans. EDUCATION: Depending on whether you want to teach at a college, go into industry, or work for a research lab, your educational path will be slightly different. Start with an undergraduate degree, usually in Earth Science; you'll need at least a master's degree if you want to teach, and to be a tenured professor at a research institution, a PhD. Strong background in math, physics, Earth science, and solid mechanics is also important. USEFUL SKILLS: Computer programming, writing (for writing grant proposals), communication, and leadership skills. How to get in: Working in labs as a student, publishing papers (as a part of a professor's or student's research team), and going to scientific meetings to network are all ways to get yourself out there and meet people that can help you. If you're interested in research, you'll need your name on as many publications as possible by the time you start looking for a job. CAREER PATH: In industry or a research lab, getting an internship while in school then pursuing a job at any lab or related company will get your foot in the door. In academic positions, you'll start out as a researcher with some teaching responsibilities; after years of research and experience, you can become a professor with full tenure. PAYBACK: For an academic researcher with a master's degree and 3-5 years of experience, the average salary is about $69,000. With a PhD, you'll make more. If you work in industry, you can work with a bachelor's or a master's and make anywhere from $40,000-$50,000, depending on degree and experience. DOWNSIDES: Securing funding can be a challenge. You spend a good part of your time writing proposals to make sure that your research is paid for, so that you can continue working on what you love. FUTURE OF JOB: Teaching positions at universities are becoming increasingly competitive, as are positions at research labs. Jobs in industry (oil, mining, geotechnical) vary, depending on the market, but can also be competitive depending on the economy and region. NETWORKING: Professional Societies: American Geophysical Union Seismological Society of America Geological Society of America Other Resources: Southern California Earthquake Center (has student internships and other educational resources) Jet Propulsion Laboratory (look on Education page, has lots of resources) NASA (education page has resources) US Geological Survey (has a bunch of educational resources) Earth Science departments at universities/colleges Produced, shot and edited for the National Science Foundation by instructors from the Gigniks program. -Ali Sanford (LACES 12th grade)

Jenny talks about her interest in engineering and science as a means to be useful and solve problems and the importance of education in the Navajo culture in general. She explains how resource extraction such as coal mining has had a negative environmental impact on the Navajo land and how, in the past, few tribal members have had the knowledge and training to deal with these problems or to educate the public about ways to solve them. Today, she is committed to sharing with others what she has learned through her studies and to helping scientists communicate their findings to the broader community. Video produced by McLean Media.

This is a diary of a girl that decided to completely change her life. I am 35. Born & raised in a small town in Kazakhstan, studied in Russia and US, lived in the UK and Australia. I Have always been a creative kind and loved drawing, painting, playing guitar and sewing, but happened to study geology and even climbed the career ladder in Mining Industry. The feeling of internal imbalance has pushed me to move countries. But it is only now that I realised it! If you are happy with what you are doing, you will be happy anywhere! I decided to quit my job and return to my childhood dreams. I’ve decided to start up my own clothing label! I am calling it Miss Cosmopolita. Why? It is basically who I am. A girl who travels explores inner-self, as well as the world. A girl who is curious and dreams a lot. A girl who is not afraid to do what she wants. She transforms herself while travelling and learning other cultures and she transforms others, by inspiring them to look at their lives differently! This channel is my diary of a life-changing journey. Here I will be transforming from a geologist to a business owner of the clothing label. I will be learning new skills, I will be having tough times and happy times. I am also into healthy eating (veganism + interested in raw eating), learning about meditation and yoga and self-development, which I will be sharing with you too! I will be documenting my thoughts just like in a diary. I am doing it for 3 reasons: 1) I want to remember how it all began (doesn’t matter failure or success) I will look at it as an experiment and laugh at it when I am 80 years old 2) I want to share my journey with you and possibly inspire you in some way (you choose!! There is plenty of room) 3) I am looking for support from like-minded people. It has been pretty difficult to find these people around me, so I am hoping the Internet will help me do that! 😊 Well, buckle up and welcome aboard!!! Let’s go! Miss Cosmopolita

Take this as a reminder for you to thank Mother Earth for that poppin' highlight. Thank you for watching my short mineralogy lesson on muscovite. Did you check your labels? Let me know in the comments below. References: Lapot. (2010). Muscovite window. Retrieved from https://commons.wikimedia.org/wiki/File:Muscovite_window.jpg Marshak, S. (2009). Essentials of geology. New York, NY: W.W. Norton & Company. Muscovite. (n.d.). In Encyclopædia Britannica online. Retreived from https://www.britannica.com/science/muscovite-mineral Neese, W. D. (1999). Introduction to mineralogy. Oxford: Oxford University Press. Sterrett, D. B. (1923). Mica deposits of the United States. United States Geological Survey, Bulletin 740. https://doi.org/10.3133/b740 Transcript : 0:01 What’s up crystal chicks? How often do you visit your local beauty counter or drugstore to find the products that create rockin' glam looks? Little did you know, some of your favorite glosses and shadows contain muscovite, a common mica mineral that gives cosmetics that perfect sparkle in the light. 0:18 To be considered a mineral, muscovite occurs naturally as a solid and has a definable chemical composition [KAl2(Si3AlO10)(OH2)]. Additionally, it’s inorganic, meaning there are no carbon-hydrogen bonds, like sugar. Lastly, it has a crystalline structure. Under special microscopes, we can see that muscovite’s atoms are fixed in a specific, orderly pattern. 0:41 A key muscovite characteristic is its cleavage. Since it’s crystal structure has weak bonds in one direction, it can easily split into thin sheets. This feature made it useful to create window panes in Russia, where it was known as Muscovy glass. 0:58 On Mohs hardness scale of 1-10, muscovite is rated as a 2, which is softer than a fingernail. When it is ground, its pearly luster is comparable to the shimmer of this eyeshadow. 1:11 In nature, muscovite can be found in igneous and sedimentary rocks, but most commonly in metamorphic rocks, specifically those with foliation. Derived from Greek words meta and morphe, metamorphic means “to change form.” During metamorphism, pre-existing rock (also called a protolith) is subjected to intense heat, pressure, and sometimes hot water. Foliation occurs because some of the minerals have a preferred orientation when the rock is exposed to the pressure and temperature changes, which in turn, gives metamorphic rocks their striped appearance. 1:50 The protolith for metamorphic rocks containing muscovite are usually shales, sedimentary rocks that are made of clay and silt. Without melting, the atoms recrystallize to change the shape and size of the minerals or form new minerals. The intensity of metamorphism indicates how minerals develop. The most common types of foliated rocks include slate, phyllite, schist, and gneiss. 2:17 Some of the most valuable muscovite used in cosmetics is sourced from pegmatites, a type of igneous rocks with extremely large crystals because the magma has more time to cool. 2:28 In the early 1800s, muscovite was mined in the United States throughout the Appalachian and Rocky Mountain regions but production later declined as industry preferred inexpensive micas from India. 2:41 Now that you know how muscovite is formed, check your makeup bag. There’s a great chance Earth’s glitter bomb is right at your fingertips.

Title: Using crystal ages and compositions to understand how volcanoes come back to life Abstract: Volcanoes spend most of their existence not erupting. This doesn’t mean that there aren’t a multitude of magmatic processes going on underneath. These might include intrusions of new magma, crystallization of existing magma, magma mixing and movement of crystals through the “crystal mush” that sits under the volcano. These processes all leave their compositional and temporal signature on the crystals that form and are subsequently incorporated into the magma that does erupt. I will discuss how examination of zircon crystals in magma can help us unravel the timing and nature of events that occur between volcanic eruptions with a focus on the evolution of the Lassen Volcanic Center in California. Overall, current trace element and U-Th disequilibria age data derived from zircon suggests that an otherwise moribund magmatic system can be brought back to life (rejuvenated) by new intrusions of magmatic that are geologically ephemeral, lasting years to millennia. This conclusion means that the events that lead to the 1915 eruption at Lassen Peak unfolded rapidly before the explosive eruption, the only to occur in California in the last century.
