Details of water cooled copper coils as part of the MOLLER Experiment is seen inside the SRF Test Lab at Jefferson Lab in Newport News, Va., on Wednesday, May 9, 2024. (Aileen Devlin | Jefferson Lab)
The Measurement of a Lepton-Lepton Electroweak Reaction (MOLLER) experiment proposes to measure the parity-violating asymmetry in electron-electron (Møller) scattering. The measurement will be carried out at Jefferson Laboratory's state-of-the-art accelerator by rapidly flipping the longitudinal polarization of electrons that have been accelerated to 11 GeV and observing the resulting fractional difference in the probability of these electrons scattering off atomic electrons in a liquid hydrogen target. This asymmetry is proportional to the weak charge of the electron, which in turn is a function of the electroweak mixing angle, a fundamental parameter of the electroweak theory. The accuracy of the proposed measurement allows for a low energy determination of the mixing angle with precision on par with the two best measurements at electron-positron colliders.
The third part, this time I captured a father and son portrait of David and his father Friedrich-Wilhelm Kriesel a former General (Brigadegeneral) I like this one a lot. I think it reflects perfectly the great energy these guys have.

WiDS Vancouver is an independent event to coincide with the annual Global Women in Data Science (WiDS) Conference held at Stanford University and an estimated 150+ locations worldwide. All genders are invited to attend WiDS regional events, which features outstanding women doing outstanding work.
The Global WiDS Conference aims to inspire and educate data scientists worldwide, regardless of gender, and to support women in the field.
This one-day technical conference provides an opportunity to hear about the latest data science related research and applications in a number of domains, and connect with others in the field.
Thanks to Duong Vu and Ha Dinh for co-organizing the event, and Microsoft for providing the space. Original photo by event photographer (?), post-processed by me.

This is a map showing the density and distribution of caves in Kentucky, Tennessee, Alabama, and Georgia (KTAG). The strong line of density extending north-east from the intersection of Tennessee, Alabama, and Georgia shows the western escarpment of the Cumberland Plateau where Mississippian aged limestones outcrop and are exposed to weathering processes.
At the southern end of the Cumberland Plateau it becomes more heavily dissected, with islands of Plateau present amidst the Highland Rim. Along the margins of these islands caves can be exposed, which explains the dispersion at the southern extent of the Plateau.
Central and Western Kentucky show a secondary area of cave density; a ring of Mississippian aged carbonates has been exposed from the weathering of the Cincinnati Arch. Mammoth Cave resides in the densest part of this region.
This map was created using data from the following sources:
Alabama Cave Survey (ACS)
Georgia Speleological Society (GSS)
Kentucky Speleological Society (KSS)
Tennessee Cave Survey (TCS)
ArcMap 10.7.1 by ESRI was used to create the map. Workflow follows.
For Tennessee, Alabama, and Georgia:
· Reference E1 (only one entrance per cave; the first documented entrance) points
· Spatially join points to county feature class and display count as label
· Kernel Density
For Kentucky:
· Summarize county table and tabular join to county feature class and display count as label
· Summarize 7.5' quadrangle table and tabular join to 7.5' quadrangle feature class
· Feature to point (create centroid) of quadrangle feature class; preserve count attribute
· Kernel density with new quad centroid feature class with count as Z attribute

My inspired series goes on with David Kriesel , a data scientist from Bonn
You might know him in connection with the Xerox bug he discovered in 2013.
David also does a lot of talks. The combination of data science and talks may sound boring to some of you. But this is only because you never watched one of David’s extremely entertaining and very interesting talks.

Artificial Unintelligence: How Computers Misunderstand the World
Graphic recording from talk by Meredith Brussard, at Faculty Technology Day 2019 on Tuesday, May 14, 2019 (Fordham IT).
For additional information and resources from the event, please visit our conference website.
Data journalist Meredith Broussard is an assistant professor at the Arthur L. Carter Journalism Institute of New York University and the author of “Artificial Unintelligence: How Computers Misunderstand the World.”.
Her academic research focuses on artificial intelligence in investigative reporting, with a particular interest in using data analysis for social good. She is also interested in reproducible research issues and is developing methods for preserving innovative digital journalism projects in scholarly archives so that we can read today’s news on tomorrow’s computers.
Broussard is an affiliate faculty member at the Moore Sloan Data Science Environment at the NYU Center for Data Science, a 2019 Reynolds Journalism Institute Fellow, and her work has been supported by the Institute of Museum & Library Services as well as the Tow Center at Columbia Journalism School. A former features editor at the Philadelphia Inquirer, she has also worked as a software developer at AT&T Bell Labs and the MIT Media Lab. Her features and essays have appeared in The Atlantic, Slate, and other outlets.
