Springtime brings tornado outbreaks and devastation across the United States. The good news for those of us who anxiously eye the skies: Tornado science is rapidly evolving and improving, as are the means by which we detect funnel clouds and warn of their approach.

Get up to speed with what’s known about tornadoes with the help of Dr. Jeffery Halverson, a severe storm expert with the Washington Post Capital Weather Gang who previously has given excellent Profs and Pints talks on hurricanes and snowstorms.

He’ll describe how, with the help of research conducted by tornado hunters, meteorologists are using ever more sophisticated computer simulations and datasets to try to “crack the code” when it comes to how and where tornadoes form.

We’ll look at how science teams wielding Portable Doppler Radars on small trucks are learning that tornado wind speeds are much stronger than once presumed. We’ll consider how decades of data are changing how we think about “Tornado Alley,” and we’ll review what’s known about the relationship between tornadoes and climate change.

Professor Halverson will conclude by discussing the technological strides being made in terms of tornado warning and detection, and how tornado scientists are teaming up with social scientists to gain a better understanding of what leaves us vulnerable to natural hazards. (Doors: $17, or $15 with a student ID. Bar doors open at 5 pm. The talk starts at 6:30.)

Profs and Pints Baltimore presents: "Eugenics Then and Now,” on a dangerous movement in science and its lessons for current research, with Carlo Quintanilla, molecular biologist and health science policy analyst at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

[Doors open at 3. The talk starts at 4:30. The room is open seating. Advance tickets: $13.50 plus sales tax and processing fees. Available at https://events.ticketleap.com/tickets/profsandpints/baltimore-eugenics ]

Global concerns about the return of eugenic thinking were reignited by Chinese scientist He Jiankui’s 2018 announcement of the first gene-edited babies, Lulu and Nana. He was quickly condemned by the scientific community and jailed for illegal medical practice, but he and others around the world continue experiments with goals echoing eugenic ambitions.

As genetic technologies advance at extraordinary speed, society faces a new set of ethical questions about shaping the traits of future generations. Are we entering a new era of eugenics? If so, how should we respond?

Hear such questions tackled by Carlo Quintanilla, who studied rare genetic mutations in human disease as a graduate research scientist and instructor at the University of Texas Southwestern Medical Center and now works at the intersection of genomic medicine, science, and society.

Dr. Quintanilla will begin by discussing the origins and history of eugenics, tracing its development in the 19th and 20th centuries as an idea, a scientific movement, and a set of policies. He’ll examine the rise of Social Darwinism in the United Kingdom, forced sterilization programs in the United States, and the atrocities committed by the Third Reich in the name of “racial hygiene.”

From there, he’ll explore how our ability to shape human health and heredity have been transformed by modern reproductive and genetic technologies such as in vitro fertilization, prenatal and embryo screening, and genome editing. You’ll learn how these tools hold enormous promise when it comes to the prevention and cure of rare and debilitating genetic conditions, yet also raise profound questions related to their potential enablement of a new, technologically driven form of eugenics.

Dr. Quintanilla will then delve into the ongoing debate among scientists, bioethicists, and policymakers over what should be classified as eugenics today. He’ll highlight recent controversial uses of genetic and reproductive technologies that are pushing ethical boundaries faster than society can define them, from embryo selection for traits like IQ and height to speculative military interest in genetically enhanced soldiers. These examples raise urgent questions: Where should society draw ethical boundaries? Who gets to decide? And is the term “eugenics” still useful for guiding policy and public debate?

We’ll close by examining the social, political, and regulatory forces that will determine the future, considering whether they will restrain the push toward further genetic control or accelerate it. (Doors: $17, or $15 with a student ID.)

Profs and Pints Baltimore presents: “The Physics of Baseball,” with Scott Paulson, professor of physics and interdisciplinary liberal studies at James Madison University.

Profs and Pints is offering baseball fans an even bigger treat than Cracker Jack, an exploration of the physics underlying their beloved sport.

Professor Scott Paulson, who regularly teaches introductory physics classes that make the physics behind real-world phenomena accessible to all, will discuss the forces and phenomena that come into play in baseball during pitching, batting, and fielding. He’ll toss you basic physics concepts that help explain how baseball’s routine plays got to be that way, and he’ll explain what’s going on in some situations where the laws of physics seem to be violated by what’s happening on the field.

Ever wondered why curveballs curve or knuckleballs behave so strangely? You’ll learn how Newton’s laws and the Magnus force explain how pitchers get drastically different results from subtle differences in their releases.

Curious about what exactly the “sweet spot” of the bat is? Ever wondered how big an advantage batters get from the thin air of Mile High Stadium? We’ll explore the physics of the batted ball, examining the phenomena of waves and analyzing the interaction of ball, bat and batter with the help of high-speed video.

During one of the more exciting scenarios in a baseball game—the close play at the plate—fans often see outfielders throw to an infielder rather than directly to home. We’ll look at the pros and cons of this relay play, known as a “cut-off,” in the context of the physics of projectile motion.

Finally, we will also look into high-profile cheating scandals involving corked bats and doctored balls. Dr. Paulson will present models to explain how these alterations to the equipment can benefit the batter and pitcher respectively, and he’ll discuss how much these models are backed up by data.

These few hours will forever enhance your enjoyment of time at the ballpark. (Doors: $17, or $15 with a student ID. Bar doors open at 5 pm. The talk starts at 6:30.)

Profs and Pints Baltimore presents: “What Digital Detectives Find,” on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert.

[Doors open at 5. The talk starts at 6:30. The room is open seating. Advance tickets: $13.50 plus sales tax and processing fees. Available at https://events.ticketleap.com/tickets/profsandpints/baltimore-digital-detectives ]

What happens when you delete digital data such as a picture, video, or email message?

The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever.

Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years.

You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered.

Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not.

Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID.)
