## Lab Math: A Handbook of Measurements, Calculations, and Other Quantitative Skills for Use at the BenchWork at the biology bench requires an ever-increasing knowledge of mathematical methods and formulae. In Lab Math,Dany Spencer Adams has compiled the most common mathematical concepts and methods in molecular biology, and provided clear, straightforward guidance on their application to research investigations. Subjects range from basics such as scientific notation and measuring and making solutions, to more complex activities like quantifying and designing nucleic acids and analyzing protein activity. Tips on how to present mathematical data and statistical analysis are included. A reference section features useful tables, conversion charts and â€œplug and chugâ€ equations for experimental procedures. This volume is an excellent, structured source of information that in many laboratories is often scattered and informally organized. |
