[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Understanding the Sports Betting Industry,”** an exploration of how legalized gambling on sports is affecting March Madness and athletics as a whole, with Matt Winkler, founder of American University’s online master’s program in sports analytics and management, adjunct professor at AU’s Kogod School of Business, former sports executive, and scholar and teacher of sports management, business, analytics, and technology. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-sports-betting](https://events.ticketleap.com/tickets/profsandpints/dc-sports-betting) .] Sports betting has undergone explosive growth in the United States in the wake of a 2018 Supreme Court decision lifting the federal ban on it. Its widespread legalization by the states, combined with increased integration of sports and technology, has given rise to an industry with billions in annual revenue. This growth is not only reshaping the landscape for major sports leagues like the NFL and NBA but is also profoundly impacting global events such as the NCAA Tournament and FIFA World Cup. As more fans engage with sports through betting platforms, the dynamics of fan engagement, sports marketing, and even match and game governance are changing. Serious questions are being raised about sports betting’s integrity, regulation, and economic impact. Gain insights into the rapidly evolving global sports betting industry and its profound impact on March Madness, other athletic contests, and professional and collegiate sports. Professor Matt Winkler’s extensive knowledge of the sports economy and betting practices, combined with his years of industry experience—with the NCAA, Major League Soccer, the NHL, WNBA, the Olympics, and the World Cup—make coming to hear him speak an experience sure to pay off. He’ll share insight into trends such as the rise of mobile betting and the emergence of prediction markets. He’ll discuss the significance of sports integrity in gaming markets, the ethical considerations surrounding sports betting, and the various safeguards and regulatory approaches used to protect consumers, reduce problem gambling, and ensure the integrity of sports. Among the areas we’ll explore: The economic impact of legalized sports betting and how it affects local economies, advertising, and media rights. Why major leagues and the NCAA are partnering with betting companies and what they stand to gain from it. How betting is influencing the governance and commercial strategies of major international competitions such the Olympics and FIFA’s World Cup. Using March Madness as a case study, Professor Winkler will discuss how sports betting has altered the tournament’s viewership patterns, bracket culture, and revenue.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Search for Life Beyond Earth,”** with Måns Holmberg, postdoctoral researcher at the Space Telescope Science Institute and part of a team of astronomers looking for chemical traces of life on distant exoplanets. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-ET](https://events.ticketleap.com/tickets/profsandpints/dc-ET) .] Are we alone in the universe? While many of us have pondered that question, astronomer Måns Holmberg of Baltimore’s Space Telescope Science Institute is seriously focused on answering it. Last year he was part of a Cambridge-led team of astronomers who generated worldwide headlines by announcing that they had discovered potential evidence of a gas produced almost exclusively by life in the James Webb Space Telescope’s data from the atmosphere of a distant world. Dr. Holmberg will talk about how the search for life elsewhere is being conducted and what strides are being made on that front. He’ll describe what it would take to confirm signs of life on such a world, what challenges remain, and how the next wave of observations could ultimately tip the scales. Dr. Holmberg also will look at the role being played by the James Webb Space Telescope (JWST), how it uses infrared light to decode the chemical composition of strange atmospheres, and how it has left us closer than ever to answering the question of whether life exists elsewhere. He’ll discuss astronomers’ growing interest in a new class of exoplanets known as “Hycean worlds”—ocean-covered planets with hydrogen-rich atmospheres that could be surprisingly hospitable to life. We’ll visit K2-18 b, a distant world around twice the size of Earth that orbits in the habitable zone of a cool red-dwarf star 120 light-years away, and discuss why it has become one of the most interesting exoplanets in the search for life. Recent observations from JWST have revealed something extraordinary: the atmosphere of planet K2-18 b contains carbon-based molecules like methane and carbon dioxide and possibly even dimethyl sulfide (DMS), a gas that, on Earth, is almost exclusively produced by life. Dr. Holmberg will discuss what makes DMS a compelling (though not yet definitive) biosignature candidate. You’ll emerge from the talk with a much richer appreciation of the immense possibilities out there among the stars. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: An illustration showing what the exoplanet K2-18 b might look like. Source: NASA, ESA, CSA, Joseph Olmsted (STScI) / Wikimedia Commons

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.
