The Black Rabbit Magic is a folklore that has been passed down through generations. It is said to be a magical creature that brings both good luck and misfortune to those who encounter it. The origins of the Black Rabbit Magic are unclear, but it is believed to have originated in Celtic folklore. According to legend, the Black Rabbit appears at random and can take on different forms. It is said to be small and agile, with jet black fur that enables it to blend into the shadows. It has large, glowing red eyes and an air of mystery surrounding it.

Darren Pagan earned a B.S. degree in mechanical engineering from Columbia University in 2010 and his Ph.D. in mechanical engineering from Cornell University in 2016. His dissertation research focused on developing crystal kinematic and scattering models for quantifying heterogeneous plastic deformation in single crystals during thermo-mechanical loading from in-situ X-ray data. As a postdoctoral researcher at Lawrence Livermore National Laboratory, Darren developed new methods for integrating diffraction data with crystal plasticity finite element modeling and used X-ray techniques to characterize granular material deformation in-situ under quasi-static and dynamic loading conditions.

Research Projects:Darren’s research focuses on developing data analysis methods for quantifying material deformation, integrating mechanical and scattering models, and expanding experimental capabilities for characterizing microstructure evolution during processing and performance testing of metallic alloys and composites. The goal of this research is to extract quantitative measures of microstructure evolution in-situ to develop, calibrate, and validate computational models and to accelerate the design of superior material systems.
A current research focus is developing connections between the output of machine learning data dimensionality techniques and more traditional physics-based modeling approaches. The traditional approach to extracting material information from data is to hypothesize a material response, model the material response and probe interactions, and then compare or fit the model to the data. One downside to such an approach is that the material response must be assumed a priori, naturally limiting the information that can be extracted. A compelling alternative approach is to apply unsupervised learning techniques to the raw data to distill the encoded information down to its lowest dimensional descriptors. Analyzing how these low dimensional descriptors are grouped spatially and/or evolve with time can provide insights into exactly how and when the most critical portions of microstructure develop, with new fundamental science coming from prediction of how physical quantities evolve in-line with more traditional, physically-based state descriptors.

The pacing was all over the place, with long stretches of boredom followed by rushed action sequences that felt disjointed. The main character was unremarkable and lacked any compelling qualities to root for. The romance in the story was forced and lacked chemistry. Unfortunately, I couldn't find much to enjoy in this book, and I was left feeling underwhelmed.
4. Emily - 2/5 - I struggled to get through "Black Rabbit Magic". The writing was clunky and full of grammatical errors that distracted from the story. The plot was cliché and predictable, with unoriginal twists that felt overdone. The world-building was underdeveloped, leaving me with more questions than answers. Overall, the book lacked polish and refinement, and I wouldn't recommend it to others.
