LikedWhy do so many of us get nervous when public speaking? Communication expert Lawrence Bernstein says the key to dealing with the pressure is as simple as having a casual chat. He introduces the "coffee shop test" as a way to help you overcome nerves, connect with your audience and deliver a message that truly resonates. After the talk, Modupe explains a similar approach in academia called the "Grandma test," and how public speaking can be as simple as a conversation with grandma.

Bedrock: Earth's Earliest History
Earth’s crust is shattered into dozens of moving plates, but many other worlds operate very differently. What are some alternatives to plate tectonics? Today, we’ll compare tectonics on Earth with tectonics on other planets, through the lens of 3.9 billion-year-old rocks from Greenland. On the way, we’ll visit the westernmost town in the USA, visit one of our cosmic neighbors, and learn about the Occam’s Razor of geology. Extra Credit: find today’s planet in the night sky, drop a pebble every day this week and see if anything changes, or read “The Long Rain” by Ray Bradbury.

Bedrock: Earth's Earliest History
Hi folks, If you’re a long-term listener, you know this show often takes long, multi-week breaks. This break has been much longer than normal, and will likely continue for a few months. What’s going on? Right now, I have one goal on my mind: to find a new, permanent job. My three-year contract at Grand Valley State University will end in April. I knew this going in, and it’s public information, so don’t worry about any dirt being spilled. In the past three months I have applied for dozens of jobs, and that number will double before year’s end. Each application takes time. I also have a full teaching schedule and I’m supervising undergraduate research. In short, there’s simply no time to make the show right now. I don’t know where I’ll be in six months, and that’s honestly a very stressful situation. But things are looking up- I’ve had a few interviews, and jobs are still being posted. When I find a permanent position, hopefully by early 2025, I will let you all know and finally return to Bedrock, both the show and in my own life. In the meantime, thank you as always for your patience and enthusiasm. If you’ve finished the show, you can recommend it to a science-curious friend. You can always drop a line at bedrock.mailbox@gmail.com , it always makes my day. See you next time, whenever that may be.…

Hi folks! I've just been invited by my university to join a field trip to Iceland next week, one of the best spots in the world to study geology. This means there will be a slight hiccup in our programming. Episode 38 will drop early next week, while Episode 39 will hopefully drop the first week of August. If I have time and space, I might try some experimental episodes from Iceland itself, field diaries and interviews, but no promises yet. As always, thanks for your patience and support!…

Why are some ancient rocks well-preserved, while others are extremely messed up? Today, we'll take a side quest from our Greenland arc to learn more about metamorphosis, which changes rocks beneath our feet. On the way, we'll transform toast into cookies, take an elevator ride deep into the crust, and meet an ancient rock with a babyface. Extra credit: make some toast, or go looking for butterflies.…

What is the oldest *major* slice of rock, one that's relatively well-preserved, one that's fueled a half-century of research? The episode's name kinda gives it away, but stay tuned as we meet the last location of Season 2: a series of rocks near Greenland's capital. Along the way, we'll meet the different groups of people who have settled on this remote island, and a geologist from the other side of the world. I'll also take a brief detour into why I unfortunately can't talk about every single ancient rock out there. Extra Credit: Find a choir to sing in, or play some ping-pong.…

Where does humanity get most of its' iron, and what do these rocks tell us about the ancient Earth? Today, we'll learn about banded iron formations, the backbone of the modern steel industry an important stop in the search for early life and oxygen, and a rock that is impossible to make today. It's rare to find a rock as important to both economics and research. Along the way, we'll take a breath of fresh air, meet orange pond scum in a forest stream, and find a dagger carved from a meteorite.

What's the next step after the oldest rock on Earth? Today, we'll move the story forward 200 million years and 1,000 miles. The time : 3.8 billion years ago... or maybe much older (March 3 on the Earth Calendar). The place: Nuvvuagittuq (noo-voo-ah-git-took), Quebec, Canada, in the lands of the Inuit. In this episode, we'll learn how this seaside outcrop was found and the ongoing debate about its' exact age. Depending on who you talk to, these are either the second-oldest rocks on Earth, or almost as old as the Earth itself.…

If the sun was dimmer 4 billion years ago, how did the Earth stay warm? Today, we learn how just a small percent of Earth's atmosphere goes a long way in controlling global climate, both today and in the ancient past. Along the way, we'll visit an imaginary frozen Earth without any sun, a hazy giant moon of Saturn, and learn exactly what the greenhouse effect is. Extra credit: Visit a greenhouse, or find a cleaning product with ammonia.…

How has the Sun changed over the past 4 billion years? While the Sun may seem unalterable, it has brightened dramatically over Earth's history, with major implications for our world.
