Как завоевывать друзей и оказывать влияние на людей

Дейл Карнеги говорил, что легче сделать миллион долларов, чем добавить фразу в английский язык. «Как завоевывать друзей и оказывать влияние на людей» стала именно такой фразой, цитируемой, пересказываемой, пародируемой, используемой с неисчислимым множеством оттенков в различных текстах – от политических листовок до романов.

Mathematical Methods in Quantum Mechanics

This manuscript provides a self-contained introduction to mathematical methods in quantum mechanics (spectral theory) with applications to Schr¨odinger operators. The first part covers mathematical foundations of quantum mechanics from self-adjointness, the spectral theorem, quantum dynamics (including Stone’s and the RAGE theorem) to perturbation theory for self-adjoint operators. The second part starts with a detailed study of the free Schr¨odinger operator respectively position, momentum and angular momentum operators. Then we develop Weyl-Titchmarsh theory for Sturm-Liouville operators and apply it to spherically symmetric problems, in particular to the hydrogen atom. Next we investigate self-adjointness of atomic Schr¨odinger operators and their essential spectrum, in particular the HVZ theorem. Finally we have a look at scattering theory and prove asymptotic completeness in the short range case.

МАҲАЛЛИЙ ХОМ АШЁЛАР АСОСИДА КЎМИР БРИКЕТИ ИШЛАБ ЧИҚАРИШ УЧУН БОҒЛОВЧИ ОЛИШ ТЕХНОЛОГИЯСИНИ ЯРАТИШ

Дунёда саноат иқтисодиёти тармоқларининг жадал ривожланиши, аҳоли сони ҳамда ишлаб чиқариш тармоқларининг ўсиши натижасида нефть, газ, кўмир ва бошка турдаги ёқилғиларга бўлган эҳтиёж янада ортиб бормоқда. Бу борада кўмир ёқилғиси алоҳида эътиборга эгадир. Лекин кўмирнинг ташқи механик таъсирлар натижасида майдаланиши, яроқсиз ҳолга келиши, ўз навбатида экологик муаммоларни келтириб чикаради. Шунинг учун ҳосил бўлган кўмир майда бўлаклари асосида брикетлаш орқали ёнувчанлиги ва мустаҳкамлигини ошириш учун боғловчи моддалар ёрдамида маҳсус қурилмаларда брикетлаш катта аҳамиятга эга.

Mathematical Methods for Physicists: A concise introduction

This text is designed for an intermediate-level, two-semester undergraduate course in mathematical physics. It provides an accessible account of most of the current, important mathematical tools required in physics these days. It is assumed that the reader has an adequate preparation in general physics and calculus. The book bridges the gap between an introductory physics course and more advanced courses in classical mechanics, electricity and magnetism, quantum mechanics, and thermal and statistical physics. The text contains a large number of worked examples to illustrate the mathematical techniques developed and to show their relevance to physics. The book is designed primarily for undergraduate physics majors, but could also be used by students in other subjects, such as engineering, astronomy and mathematics.

Mathematica for Theoretical Physics Electrodynamics, Quantum Mechanics, General Relativity, and Fractals

This second edition of Mathematica in Theoretical Physics seeks to prevent the objectives and emphasis of the previous edition. It is extended to include a full course in classical mechanics, new examples in quantum mechanics, and measurement methods for fractals. In addition, there is an extension of the fractal's chapter by a fractional calculus. The additional material and examples enlarged the text so much that we decided to divide the book in two volumes. The first volume covers classical mechanics and nonlinear dynamics. The second volume starts with electrodynamics, adds quantum mechanics and general relativity, and ends with fractals. Because of the inclusion of new materials, it was necessary to restructure the text. The main differences are concerned with the chapter on nonlinear dynamics. This chapter discusses mainly classical field theory and, thus, it was appropriate to locate it in line with the classical mechanics chapter.

Mathematica for Theoretical Physics

As physicists, mathematicians or engineers, we are all involved with mathematical calculations in our everyday work. Most of the laborious, complicated, and time-consuming calculations have to be done over and over again if we want to check the validity of our assumptions and derive new phenomena from changing models. Even in the age of computers, we often use paper and pencil to do our calculations. However, computer programs like Mathematica have revolutionized our working methods. Mathematica not only supports popular numerical calculations but also enables us to do exact analytical calculations by computer. Once we know the analytical representations of physical phenomena, we are able to use Mathematica to create graphical representations of these relations. Days of calculations by hand have shrunk to minutes by using Mathematica. Results can be verified within a few seconds, a task that took hours if not days in the past.

Сам себе финансист: Как тратить с умом и копить правильно

Отсутствие финансовой грамотности приводит к тому, что какая бы у нас ни была зарплата, мы не умеем планировать бюджет, никак не можем накопить на свою мечту, надеемся на государственную пенсию и начинаем жить в кредит. При этом есть мнение, что управление личными финансами слишком сложно и вообще это только для богатых

MATHEMATICA FOR PHYSICS

To be good at physics you no longer have to be good at calculating. When I started doing physics in the early 1970s, it was generally thought that being able to do long calculations by hand was an essential skill. But as it happens I was never very good at such calculations. And so I looked for an alternative, and before long I found one: I discovered that I did not really need to do the calculations myself I could get a computer to do them instead. My physics papers from the late 1970s were full of elaborate calculations. And from seeing this many people came to the conclusion that I must be a great calculator. But in fact that was far from the truth, and what was actually going on was that I was doing all my calculations by computer.

Materials Engineering, Science, Processing and Design

Most things can be approached in more than one way. In teaching this is especially true. The way to teach a foreign language, for example, depends on the way the student wishes to use it—to read the literature, say, or to find accommodation, order meals and buy beer. So it is with the teaching of this subject. The traditional approach to it starts with fundamentals: the electron, the atom, atomic bonding, and packing, crystallography and crystal defects. Onto this is built alloy theory, the kinetics of phase transformation and the development of microstructure on scales made visible by electron and optical microscopes. This sets the stage for the understanding and control of properties at the millimeter or centimeter scale at which they are usually measured. The approach gives little emphasis to the behavior of structures, methods for material selection, and design.

Будь лучшей версией себя. Как обычные люди становятся выдающимися

В написании этой книги участвовало много людей. Мой друг и редактор Джули Болдуин терпеливо объединила мои мысли в абзацы и главы. Эта книга не состоялась бы без ее мастерства. Том Бентли и Джоэл Кэнфилд отправили меня в это путешествие. Они прочли оригинальную рукопись и воодушевили меня раскрыться настолько, чтобы написать о самых тяжелых временах в моей жизни.

ЛАГОХИЛИН ҲОСИЛАЛАРИ СИНТЕЗИ, СУПРАМОЛЕКУЛЯР КОМПЛЕКСЛАРИНИ ОЛИШ ВА УЛАРНИНГ БИОЛОГИК ФАОЛЛИГИ

Бугунги кунда дунё миқёсида ўсимликлардан биологик фаол моддаларни ажратиб олиш, уларни кимёвий модификация қилиш, махсус фаолликларини ўрганиш ва саноат миқёсида ишлаб чиқариш усулларини амалиётга тадбиқ қилиш бўйича кўплаб илмий изланишлар олиб борилмоқда. Тиббиётда ўсимликлардан олинадиган дори воситалари яллиғланиш, ўткир ва сурункали оғриқлар билан кечувчи турли патологик ҳолатларни, юрак, қон-томир тизими касалликларини олдини олиш ва даволашда ишлатиб келинмоқда, чунки синтез усулида олинган дори воситалари узлуксиз қабул қилиниши инсон организимда нохуш ҳолатларни келтириб чиқаради. Шунинг учун, ўсимликлардан биологик фаол моддалар ажратиб олиш ва тиббиёт учун янги дори воситалари яратиш муҳим вазифлардан биридир.
