5Question: A science journalist is covering a study with 8 researchers and 5 interns attending a roundtable discussion. How many distinct seating arrangements are possible if no two interns can sit next to each other?

Every roundtable conversation holds more than just words—it reflects the rhythm of collaboration, respect, and strategy. When a science journalist covers a complex study, the setting tells its own story: who sits together, who’s positioned apart, and how space influences interaction. Recently, a newsroom effort shed light on a key logistical puzzle: how many distinct seating arrangements are possible when 8 researchers and 5 interns attend a roundtable—with the strict rule that no two interns sit side by side? The question isn’t just academic—it taps into a growing interest in how group dynamics shape scientific discourse, especially as rising interdisciplinary collaboration becomes central to modern research. With more scientists gaining public platforms and interns gaining visibility as future experts, understanding the math behind seating logic reveals both precision and real-world relevance.
