[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs](https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

*You must read the following NVHC Sign-in Sheet Statement/Liability Disclaimer, [https://nvhc.com/signin.pdf](https://nvhc.com/signin.pdf) and then answer the question that you will see when you RSVP with "I accept" to be permitted on the hike.* Distance: 3.5 miles Elevation change: about 100' Earth Day is Wednesday, April 22! How far have we come since the first Earth Day in 1970? Join us at the 500-acre Lake Accotink Park, a surprising retreat in the middle of suburban Fairfax County. We'll walk partly on and partly off the main trail and along the lake shore on natural surface trails (about 4 miles total). We'll walk by an active eagle nest that is visible from the trail, unless the leaves are out. We may see the eagles flying around the lake. We'll find a variety of native plants, including the native azalea. **We meet at the parking lot by the dam**, then hike on natural surface side trails that most park visitors don’t know about. I'm also a naturalist, so we will stop occasionally to look at spring wildflowers. Some of the terrain is hillier than the main trail around the lake, with an elevation change of about 100 feet from lowest to highest, with many short but steep hills that make for a good workout for a suburban location. The route has small rocks, roots, and a couple of small stream crossings and is not suitable for people with difficulty walking. Pace is about 2 mph average with occasional short stops for checking out nature and discussing Earth Day. Restroom: By the pavilion (about a 5-minute walk from hike start) No dogs, please Park Entry Fee: NONE [Park map](https://www.fairfaxcounty.gov/parks/sites/parks/files/Assets/documents/waterfront/lakeaccotink/lake-accotink-brochure-map.pdf) * NOTE: Alternate directions if you are coming to the Park from the direction of Tysons Corner on 495 (Beltway): You may enter the Park at an entrance on Heming Ave. From I-495, take Exit 54 East onto Braddock Road (east). From Braddock Road, turn right onto Heming Ave., then right into the parking lot for Lake Accotink Park. HOWEVER, you cannot drive from that parking lot to the hike starting place. The two parking lots are connected by a paved walkway through the Park. It's a short walk down the hill to the lake (passing restrooms at pavilion), and then follow road to the dam. Please allow 10 extra minutes once you park to find your way and to walk to the dam if you arrive that way.

Its that time of year when Brookside Gardens should be filled with bombastic spring colors. Let's take an evening stroll to check them out. We will meet up near the restrooms at Wheaton Regional Park (go left at the roundabout). We will head northeast and enter the gardens, making a large loop to see all of the perimeter areas, but not necessarily examining every exhibit. From there, we will backtrack slightly and loop past Pine Lake and the carousel on the way back to the start. Total distance should be 2.5 miles or less, depending on how much meandering we do in the garden. Our start point is about 120' higher than the gardens, but it is just one big gradual slope that you will barely notice.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Facing Fascism,”** on the history, hallmarks, and lingering power of a deadly ideology, with Kevin Matthews, professor of history at George Mason University and teacher of courses on early 20th century European history. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism](https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism) .] Few political movements have aroused as much anger and fear as fascism. But despite its legacy of violence, persecution, and genocide, fascism continues to hold a strange attraction to many. Join historian Kevin Matthews for an in-depth look at an ideology that brought death to millions in Europe and yet continues to deeply influence our politics and culture. Dr. Matthews will start by discussing how the ideology of fascism arose in the aftermath of the First World War and took hold in Europe in the 1920s and 1930s. To give you a better grasp of what exactly fascism is, he’ll discuss its central themes: Anti-democracy. Extreme nationalism and anti-communism. The use, or threat, of violence in politics. Rejection of established values such as scientific objectivity. Denial of equal rights, especially for women. The assertion of power where a power vacuum exists. We’ll examine the rise and fall of two notorious fascist dictators, Adolf Hitler of Germany and Benito Mussolini of Italy. For a time it was believed that fascism died in the ashes of the Second World War, but it clearly didn’t, and we’ll look at where it remains a political force today. Finally, we’ll examine how fascism continues to permeate popular culture in ways that trivialize it, popping up in music from punk to Madonna, with its latent eroticism making it the subject of films such as *The Night Porter.* Having been called “the most self-consciously visual of all political forms,” it enlisted fashion leaders to produce uniforms and continues today to inspire a look known as “Nazi chic.” Dr. Matthews previously has given fantastic Profs and Pints talks on Ireland’s fight for independence and on World War II German submarine attacks off our coasts. He’s sure to leave you with a much better understanding of fascism and a recognition that is has hardly gone away. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Benito Mussolini and Adolf Hitler during Mussolini's 1940 visit in Munich (photographer unknown / public domain).

Is it possible that all the world’s great spiritual and religious traditions originated from the same source, even if we refer to or understand that Source in many different ways? Throughout history, religion and religious differences have often been identified as a point of division amongst the world’s peoples, as a source of strife and contention – and even of bloodshed. But is that the whole story? Is it possible that when you look more closely at what the various religions of the world actually teach, that there is in fact much more overlap and agreement than one might initially be led to believe? Looking beyond the teachings of daily practice, are there deeper truths that unite the world’s religions? How many people actually investigate the seeming differences, or similarities, for themselves? Is it possible that they share a common thread or even originate from one common, divine source? Come join a different kind of conversation – one that welcomes every perspective in a search for the truths that unite us all – as we discuss the spiritual perspective offered by the Bahá’í Teachings on the fundamental oneness of religion. Join us for a lively discussion as we explore the purpose and role of religion in promoting true unity and the progress of us all. *"...for all religion is founded upon the love of humanity."* – Bahá’í Teachings **\*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.**
