DATAFRAME MANIPULATION: THEORY AND APPLICATIONS WITH PYTHON AND TKINTER
A DataFrame is a fundamental data structure in pandas, a powerful Python library for data manipulation and analysis, designed to handle two-dimensional, labeled data akin to a spreadsheet or SQL table. It simplifies working with tabular data by supporting various operations like filtering, sorting, grouping, and aggregating. DataFrames are easily created from lists, dictionaries, or NumPy arrays and offer flexible data handling, including managing missing values and performing input/output operations with different file formats. Key features include hierarchical indexing for multi-level grouping, time series functionality, and integration with libraries such as NumPy and Matplotlib. DataFram...
First Man
On July 20, 1969, the world stood still to watch American astronaut Neil A. Armstrong become the first person ever to step on the surface of another heavenly body. Upon his return to Earth, Armstrong was celebrated for his monumental achievement. He was also--as NASA historian Hansen reveals in this authorized biography--misunderstood. Armstrong's accomplishments as an engineer, a test pilot, and an astronaut have long been a matter of record, but Hansen's access to private documents and unpublished sources and his interviews with more than 125 subjects (including more than fifty hours with Armstrong himself) yield the first in-depth analysis of this elusive, reluctant hero.
The Alcalde
As the magazine of the Texas Exes, The Alcalde has united alumni and friends of The University of Texas at Austin for nearly 100 years. The Alcalde serves as an intellectual crossroads where UT's luminaries - artists, engineers, executives, musicians, attorneys, journalists, lawmakers, and professors among them - meet bimonthly to exchange ideas. Its pages also offer a place for Texas Exes to swap stories and share memories of Austin and their alma mater. The magazine's unique name is Spanish for "mayor" or "chief magistrate"; the nickname of the governor who signed UT into existence was "The Old Alcalde."

An East Tennessee Nightmare Lying in Wait
The men and women of Appalachia are strong and self-sufficient. In Roane County, Tennessee they most often have lived on and between the foothills of the Great Smokey Mountains. Times changed and as they did in this story, those who had become clearly isolated in their long-standing culture took change personally. They didn't like it. Leon and Rocky Houston are two such men, along with a large group of sympathetic followers. In the end that sympathy portrayed years of self-styled, anti-government lawsuits as well as the death of a sheriff's deputy and his retired, disabled ride-along officer. To believe the fifteen to twenty years of this rising storm ended in death for two men patrolling th...
No Less a Man
Through close readings of these three figures, Robinson argues that more is going on among American men than meets the casual eye - and that much of what is going on is reflected in the most popular of our art forms, detective novels, action movies, and rock music.
Focusing the Whole Brain
Imagine a technique that would allow you to conduct your own explorations into consciousness. Imagine that this technique is safe, inexpensive, easy to use, and endlessly versatile. Imagine Hemi-Sync. Invented by sound engineer Robert A. Monroe more than 30 years ago, Hemi-Sync uses audio technology to synchronize the functioning of the two hemispheres of the brain. For more than three decades, people have been finding more and more creative uses for it. So many uses, in fact, that it?s time for an overview of various practical applications Hemi-Sync appeals to professionals in many disciplines. Today trainers and workshop presenters in some twenty countries and individuals from fifty countries have traveled to attend courses employing Hemi-Sync at The Monroe Institute in Virginia. Countless more use Hemi-Sync CDs and tapes for specific purposes. Focusing the Whole Brain provides a readable introduction to a whole new world of abilities greater than you ever thought possible
