Pour yourself something warm. Let it drizzle outside. This one's for the curious.
The Mark & Toddcast is your weekly escape from the algorithm, the outrage cycle, and whatever fresh hell is trending. Broadcasting from the rainy heart of Portland, Oregon, two friends have spent 11 years and over 300 episodes doing exactly what you wish you could do at your favorite dimly lit neighborhood pub: sitting down with a pint and wandering through whatever's genuinely interesting.
Consider us comfort food for your brain.
Instead, expect pure Pacific Northwest chill and unfiltered curiosity about topics like:
-
Why we absolutely hate the sound of our own voices
-
The secret origin of the biohazard symbol
-
America’s classified, Cold War plan to nuke the moon
-
The Stanford Prison Experiment (and why it was actually kind of BS)
-
Portland’s very own infamous Barbie-hacking culture jammers
-
The unsolved mystery of the Toynbee Tiles
-
And yes... the actual science of farts
What’s in an Episode?
-
The Catch-Up: A little life banter between two longtime friends navigating the Rose City.
-
Just the Headlines: A quick spin through the weirdest, wildest science and culture news of the week.
-
The Deep Dive: A 20-minute, high-level plunge into whatever strange subject one of us couldn't stop reading about.
Meet Your Hosts:
-
Mark spent his twenties operating nuclear reactors for the Navy before coming home to Portland's Silicon Forest to keep the machines that build microchips running. Now, he’s a technical director helping companies get found online.
-
Todd has lived several lives—ad copywriter, artist, Newsweek-published writer, and an unrepentant Madonna superfan. Today, he’s a local therapist helping people untangle their stories and reconnect with the humans around them.
Pull up a chair. Grab a local beverage.
Science is funny.

This week we recap Todd's trip to Yellowstone, and focus on one of the earliest businessmen to set up shop in the new National Park: Steamboat owner/operator E.C. Waters, who was such a legendary a-hole that he was eventually completely banned from even entering the park. And in our news segment - school cellphone bans, LiveNation's Portland venue proposal, Boeing's ongoing astronaut disaster, Americans die younger, a next-gen battery storage lab in Richland, Wa., gallons of urine, Todd's new lifestyle, and much, much more. Enjoy!

"How dare one interfere with the mighty judgement of God and His wrath?!" Who knew the lightning rod was such a, well, lightning rod of controversy? Benjamin Franklin gave a gift to the world, and much like the still relevant battles pitting science against (a person's own definition of) God, not everyone wanted that gift. Burn the witches, we've got some history to learn. In the news segment: Oregon gets a C-, a person's morality changes with the season, Google declared a monopoly, a beaver causes internet outages, you won't believe where this one guy shoves an eel, and much, much more. Enjoy?

Esperanto is a language created in the late 1800s as a way for everyone in the world to have an incredibly easy-to-learn and standardized secondary language, and has had enough success that it's still used for some government, military, and wikipedia translations today - and even spawned a movie starring William Shatner speaking the language. Find out all about Esperanto in this week's episode.

After a hefty portion of news, including plans for Lloyd Center, the Portland Pickles' THC drink, the Herman the Sturgeon conspiracy, the deletion of MTV News's entire back catalog from the internet, a man with 175 children, and much, much, much more, we focus on a man called Stanislav Petrov, a Russian soldier who received warning that Americans had started a nuclear attack on Russia and had to make the ultimate decision - hope it was a fake warning, or start the nuclear annihilation of the entire planet and everyone on it. So how was your day at work?

In 1993, TV news studios started receiving calls from kids who opened their Barbies and GI Joe dolls for Christmas only to discover Barbie shouting militaristic slogans and GI Joe talking about shopping. Later parodied on The Simpsons, this bit of "culture jamming" has its origins right here in Portland (which also involves ipecac, mashed potatoes, and vomiting at a Dan Quayle appearance). All that, and much more on this week's episode.

It's nice to find a library that has every book. But what if there's a library with every book ever printed, but also every sentence, paragraph, and page that could ever be written in the future? It's a heady concept, and it's called "The Library of Babel," which has more "books" than atoms in the entire universe. It's a lot, so join us this week as we crack the book open on this fascinating subject.
