Many chemists - especially those most brilliant in their field - fail to appreciate the power of planned experimentation. They dislike the mathematical aspects of statistical analysis. In addition, these otherwise very capable chemists also dismissed predictive models based only on empirical data. Ironically, in the hands of subject matter experts like these elite chemists, the statistical methods of mixture design and analysis provide the means for rapidly converging on optimal compositions. What differentiates Formulation Simplified from the standard statistical texts on mixture design is that the authors make the topic relatively easy and fun to read. They provide a whole new collection of insighful original studies that illustrate the essentials of mixture design and analysis. Solid industrial examples are offered as problems at the end of many chapters for those who are serious about trying new tools on their own. Statistical software to do the computations can be freely accessed via a web site developed in support of this book.
Laboratory Statistics: Methods in Chemistry and Health Science, Second Edition, presents common strategies for comparing and evaluating numerical laboratory data. In particular, the text deals with the type of data and problems that laboratory scientists and students in analytical chemistry, clinical chemistry, epidemiology, and clinical research face on a daily basis. This book takes the mystery out of statistics and provides simple, hands-on instructions in the format of everyday formulas. Spreadsheet shortcuts and functions are included, along with many simple worked examples. This book is a must-have guide to applied statistics in the lab that will result in improved experimental design and analysis. This thoroughly revised second edition includes several new sections, more examples, and all formulas in Excel code.
The Fundamentals of Scientific Research: An Introductory Laboratory Manual is a laboratory manual geared towards first semester undergraduates enrolled in general biology courses focusing on cell biology. This laboratory curriculum centers on studying a single organism throughout the entire semester Serratia marcescens, or S. marcescens, a bacterium unique in its production of the red pigment prodigiosin. The manual separates the laboratory course into two separate modules. The first module familiarizes students with the organism and lab equipment by performing growth curves, Lowry protein assays, quantifying prodigiosin and ATP production, and by performing complementation studies to understand the biochemical pathway responsible for prodigiosin production. Students learn to use Microsoft Excel to prepare and present data in graphical format, and how to calculate their data into meaningful numbers that can be compared across experiments. The second module requires that the students employ UV mutagenesis to generate hyper-pigmented mutants of S. marcescens for further characterization. Students use experimental data and protocols learned in the first module to help them develop their own hypotheses, experimental protocols, and to analyze their own data. Before each lab, students are required to answer questions designed to probe their understanding of required pre-laboratory reading materials. Questions also guide the students through the development of hypotheses and predictions. Following each laboratory, students then answer a series of post-laboratory questions to guide them through the presentation and analysis of their data, and how to place their data into the context of primary literature. Students are also asked to review their initial hypotheses and predictions to determine if their conclusions are supportive. A formal laboratory report is also to be completed after each module, in a format similar to that of primary scientific literature. The Fundamentals of Scientific Research: An Introductory Laboratory Manual is an invaluable resource to undergraduates majoring in the life sciences.
This book focuses on the use of novel electron microscopy techniques to further our understanding of the physics behind electron-light interactions. It introduces and discusses the methodologies for advancing the field of electron microscopy towards a better control of electron dynamics with significantly improved temporal resolutions, and explores the burgeoning field of nanooptics - the physics of light-matter interaction at the nanoscale - whose practical applications transcend numerous fields such as energy conversion, control of chemical reactions, optically induced phase transitions, quantum cryptography, and data processing. In addition to describing analytical and numerical techniques for exploring the theoretical basis of electron-light interactions, the book showcases a number of relevant case studies, such as optical modes in gold tapers probed by electron beams and investigations of optical excitations in the topological insulator Bi2Se3. The experiments featured provide an impetus to develop more relevant theoretical models, benchmark current approximations, and even more characterization tools based on coherent electron-light interactions.
TO THE THEORY OF THE RAMAN EFFECT by J. A. KONINGSTEIN Carleton University, Ottawa, Canada D. REIDEL PUBLISHING COMPANY DORDRECHT-HOLLAND Library of Congress Catalog Card Number 72-77876 ISBN-13: 978-90-277-0276-0 e-ISBN-13: 978-94-010-2901-8 001: 10. 1007/978-94-010-2901-8 All Rights Reserved Copyright (c) 1972 by D. Reidel Publishing Company, Dordrecht, Holland Softcover reprint of the hardcover I st edition 1972 No part of this book may be reproduced in any form, by print, photoprint, microfilm, or any other means, without written permission from the publisher to M. G. INTRODUCTION This book is written particularly for chemists. Being one myself, I have on several occasions tried to find a book where the theory of molecular Raman spectroscopy is treated, and not being able to find one which satisfactorily answered the questions I wanted to see answered, I decided to try to write a book on it myself. Back in the middle fifties I was shown a Raman spectrum for the first time: some faint lines on a photographic plate. In the fall of 1971, during a visit to Moscow, I vividly remembered that spectrum when the son of Mandel'shtam showed me the first spectrum taken in Russia by his father and Landsberg in 1928. The spectrum of quartz photographed during January and February of that year showed the presence of some faint new lines and in later exposures these lines became stronger and stronger.
The modern electron microscope, as a result of recent revolutionary developments and many evolutionary ones, now yields a wealth of quantitative knowledge pertaining to structure, dynamics, and function barely matched by any other single scientific instrument. It is also poised to contribute much new spatially-resolved and time-resolved insights of central importance in the exploration of most aspects of condensed matter, ranging from the physical to the biological sciences.Whereas in all conventional EM methods, imaging, diffraction, and chemical analyses have been conducted in a static - time-integrated - manner, now it has become possible to unite the time domain with the spatial one, thereby creating four-dimensional (4D) electron microscopy. This advance is based on the fundamental concept of timed, coherent single-electron packets, or electron pulses, which are liberated with femtosecond durations. Structural phase transitions, mechanical deformations, and the embryonic stages of melting and crystallization are examples of phenomena that can now be imaged in unprecedented structural detail with high spatial resolution, and ten orders of magnitude as fast as hitherto.No monograph in existence attempts to cover the revolutionary dimensions that EM in its various modes of operation nowadays makes possible. The authors of this book chart these developments, and also compare the merits of coherent electron waves with those of synchrotron radiation. They judge it prudent to recall some important basic procedural and theoretical aspects of imaging and diffraction so that the reader may better comprehend the significance of the new vistas and applications now afoot.This book is not a vade mecum - numerous other texts are available for the practitioner for that purpose. It is instead an in-depth expose of the paradigm concepts and the developed techniques that can now be executed to gain new knowledge in the entire domain of biological and physical science, and in the four dimensions of space and time.

In volume XVI of The Collected Letters of Antoni van Leeuwenhoek, 25 letters of Van Leeuwenhoek have been included, all of them written from July 1707 to June 1712. The letters were written to six distinct addressees. The larger part was addressed to the Royal Society in London in general (sixteen letters); and to three of its fellows in particular: John Chamberlayne (280, and 281), who translated the letters of Van Leeuwenhoek for the Royal Society, Hans Sloane (297), and James Petiver (287). Five letters were addressed to Anthonie Heinsius, Grand Pensionary of Holland, who was interested in Van Leeuwenhoek's work until his death in 1720. The correspondence collected in this volume shows the lasting interest evinced by the Royal Society in Van Leeuwenhoek's work. This would change in later years. None of the letters printed here were published in Leeuwenhoek's own time, either in Dutch or in Latin. Fifteen letters to the Royal Society were more or less completely published in an English translation in the Society's Philosophical Transactions. This was also done with two letters to Chamberlayne (280, and 281), and the letter to Petiver (287). The letters to Heinsius, Sloane, and Letter 285 have not been published earlier. Of all letters published here the Dutch texts are now for the first time available in a printed edition. Every volume in the series contains the texts in the original Dutch and an English translation. The great range of subjects studied by Van Leeuwenhoek is reflected in these letters: instruments to measure water; pulmonary diseases; experiments relating to the solution of gold and silver; salt crystals and grains of sand; botanical work, such as duckweed and germination of orange pips; descriptions on protozoa; blood; spermatozoa; and health and hygiene, for example and harmfulness of tea and coffee and the benefits of cleaning teeth.

Kari Byron-former host of the wildly popular, iconic cult classic MythBusters-shows how to crash test your way through life, no lab coat required. Kari Byron's story hasn't been a straight line. She started out as a broke artist living in San Francisco, writing poems on a crowded bus on the way to one of her three jobs. Many curve balls, unexpected twists, and yes, literal and figurative explosions later, and she's one of the world's most respected women in science entertainment, blowing stuff up on national television and getting paid for it! In Crash Test Girl, Kari reveals her fascinating life story on the set of MythBusters and beyond. With her signature gusto and roll-up-your-sleeves enthusiasm, she invites readers behind the duct tape and the dynamite, to the unlikely friendships and low-budget sets that turned a crazy idea into a famously inventive show with a rabid fanbase. The truth is, Mythbusters was never meant to be a science show. But attaching a rocket to a car, riding a motorcycle on water, or lighting 500 pounds of coffee creamer on fire requires a decent understanding of chemistry, physics, and engineering. Thus, the cast and crew brought in the scientific method to work through each problem: Question. Hypothesize. Experiment. Analyze. Conclude. And as Kari came to learn in her own life, not only is the scientific method the best approach for busting myths, it's also the perfect tool for solving everyday issues, including: Career * Love * Creativity * Setbacks * Money * Sexuality * Depression * Bravery Crash Test Girl reminds us that science is for everyone, as long as you're willing to strap in, put on your safety goggles, hit a few walls, and learn from the results. Using a combination of methodical experimentation and unconventional creativity, you'll come to the most important conclusion of all: In life, sometimes you crash and burn, but you can always crash and learn.
Data Fitting in the Chemical Sciences Peter Gans, School of Chemistry, The University of Leeds, Leeds, UK Data fitting is a technique of central importance in modern experimental science. It is the means by which data is tested against a model of the experimental system, be it a theoretical or empirical model. In this book an all-round approach is adopted in which the first stage of data-fitting is seen as data collection, the second is numerical processing and the third a critical evaluation of the 'goodness' of fit in both statistical and common sense terms. Each stage is considered in detail: the sources and nature of experimental errors; the theory of least-squares fitting; probability theory; hypothesis testing, and the application of scientific criteria. The theory is complemented by three chapters on a wide range of applications. The emphasis of this book is on methodology: why certain procedures are preferred rather than how any one procedure is implemented. The author aims to assist people in extracting from their data its full information content, i.e. to use their data, not abuse it.

"I want to get at the blown glass of the early cloud chambers and
the oozing noodles of wet nuclear emulsion; to the resounding crack
of a high-voltage spark arcing across a high-tension chamber and
leaving the lab stinking of ozone; to the silent, darkened room,
with row after row of scanners sliding trackballs across projected
bubble-chamber images. Pictures and pulses--I want to know where
they came from, how pictures and counts got to be the bottom-line
data of physics." (from the preface)
For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry - not just to make pretty colors and stinky smells, but to learn how to do real lab work: purify alcohol by distillation; produce hydrogen and oxygen gas by electrolysis; smelt metallic copper from copper ore you make yourself; analyze the makeup of seawater, bone, and other common substances; synthesize oil of wintergreen from aspirin and rayon fiber from paper; perform forensics tests for fingerprints, blood, drugs, and poisons; and much more.From the 1930s through the 1970s, chemistry sets were among the most popular Christmas gifts, selling in the millions. But two decades ago, real chemistry sets began to disappear as manufacturers and retailers became concerned about liability. "The Illustrated Guide to Home Chemistry Experiments" steps up to the plate with lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab.The bulk of this book consists of 17 hands-on chapters that include multiple laboratory sessions on the following topics: Separating Mixtures; Solubility and Solutions; Colligative Properties of Solutions; Introduction to Chemical Reactions and Stoichiometry; Reduction-Oxidation (Redox) Reactions; Acid-Base Chemistry; Chemical Kinetics; Chemical Equilibrium and Le Chatelier's Principle; Gas Chemistry; Thermochemistry and Calorimetry; Electrochemistry; Photochemistry; Colloids and Suspensions; Qualitative Analysis; Quantitative Analysis; Synthesis of Useful Compounds; and Forensic Chemistry.
