It's easy to feel overwhelmed by all the podcast options out there, but narrowing down your choices to the titles that will teach you something while you listen is a good place to start. If you're interested in learning more about philosophy, science, linguistics, or history, here are podcasts to add to your queue.

1. THE HABITAT

The Habitat is the closest you can get to listening to a podcast recorded on Mars. At the start of the series, five strangers enter a dome in a remote part of Hawaii meant to simulate a future Mars habitat. Every part of their lives over the next year, from the food they eat to the spacesuits they wear when they step outside, is designed to mimic the conditions astronauts will face if they ever reach the red planet. The experiment was a way for NASA to test plans for a manned mission to Mars without leaving Earth. The podcast, which is produced by Gimlet media and hosted by science writer Lynn Levy, ends up unfolding like a season of the Real World with a science fiction twist.

2. STUFF YOU SHOULD KNOW

Can’t pick a topic to educate yourself on? Stuff You Should Know from How Stuff Works is the podcast for you. In past episodes, hosts Chuck Bryant and Josh Clark (both writers at How Stuff Works) have discussed narwhals, Frida Kahlo, LSD, Pompeii, hoarding, and Ponzi schemes. And with three episodes released a week, you won’t go long without learning about a new subject.

3. THE ALLUSIONIST

Language nerds will find a kindred spirit in Helen Zaltzman. In each episode of her Radiotopia podcast The Allusionist, the former student of Latin, French, and Old English guides listeners through the exciting world of linguistics. Past topics include swearing, small talk, and the differences between British and American English.

4. PHILOSOPHIZE THIS!

Listening to all of Philosophize This! is cheaper than taking a philosophy class—and likely more entertaining. In each episode, host Stephen West covers different thinkers and ideas from philosophy history in an approachable and informative way. The show proceeds in chronological order, starting with the pre-Socratic era and leading up most recently to Jacques Derrida.

5. MORE PERFECT

In 2016, Radiolab, one of the most popular and well-established educational podcasts out there, launched a show called More Perfect. Led by Radiolab host Jad Abumrad, each episode visits a different Supreme Court case or event that helped shape the highest court in the land. Because of that, the podcast ends up being about a lot more than just the Supreme Court, exploring topics like police brutality, gender equality, and free speech online.

6. SLOW BURN

The Watergate scandal was such a important chapter in American history that it has its own suffix—but when asked to summarize the events, many people may draw a blank. Slow Burn, a podcast from Slate, gives listeners a refresher. In eight episodes, host Leon Neyfakh tells the story of Nixon’s demise as it unfolded, all while asking whether or not citizens would be able to recognize a Watergate-sized scandal if it happened today.

7. LETTERS FROM WAR

Instead of using a broad scope to examine World War II, the Washington Post podcast Letters From War focuses on hundreds of letters exchanged by four brothers fighting in the Pacific during the period. Living U.S. military veterans tell the siblings' story while reflecting on their own experiences with war.

8. LEVAR BURTON READS

Just because you’re a grown-up doesn’t mean you have to miss out on the soothing sound of LeVar Burton’s voice reading to you. The former host of Reading Rainbow now hosts LeVar Burton Reads, a podcast from Stitcher aimed at adults. In each episode, he picks a different piece of short fiction to narrate: Just settle into a comfortable spot and listen to him tell stories by authors like Haruki Murakami, Octavia Butler, and Ursula K. Le Guin.

9. BRAINS ON!

Brains On! is an educational podcast for young audiences, but adults have something to gain from listening as well. Every week, host Molly Bloom is joined by a new kid co-host who helps her explore a different topic. Tune in for answers to questions like "What makes paint stick?" and "How do animals breathe underwater?"

10. SCIENCE VS

There’s a lot of misinformation out there; if you’re determined to sort out fact from fiction, it can be hard to know where to start. The team of “friendly fact checkers” at the Science Vs podcast from Gimlet is here to help. GMOs, meditation, birth control, Bigfoot—these are just a few of the topics that are touched upon in the weekly show. The goal of each episode is to replace any preconceived notions you have with hard science.

11. FLASH FORWARD

No one knows for sure what the future holds, but Flash Forward lays out the more interesting possibilities. Some of the potential futures that host and producer Rose Eveleth explores are more probable than others (a future where no one knows which news sources to trust isn’t hard to imagine; one where space pirates drag a second moon into orbit perhaps is), but each one is built on real science.

12. HIDDEN BRAIN

What motivates the everyday choices we make? That’s the question Shankar Vedantam tries to answer on the NPR podcast Hidden Brain. The show looks at how various unconscious patterns shape our lives, like what we wear and who we choose to spend time with.

13. PART-TIME GENIUS

The fact that it’s hosted by Mental Floss founders Will Pearson and Mangesh Hattikudur isn’t the only reason we love Part-Time Genius. The podcast from How Stuff Works wades into topics you didn’t know you were curious about, like the origins of Nickelodeon and the hidden secrets at the Vatican. Each episode will leave you feeling educated and entertained at the same time.

14. ASTRONOMY CAST

It’s a big universe out there—if you want to learn as much about it as possible, start with Astronomy Cast. Fraser Cain, publisher of the popular site Universe Today, and Dr. Pamela L. Gay, director of the virtual research facility CosmoQuest, host the podcast. They cover a wide range of topics, from the animals we’ve sent to orbit to the color of the universe.

15. SCIENCE OF HAPPINESS

The Science of Happiness podcast from PRI is here to improve your life, one 20-minute episode at a time. Science has proven that adopting certain practices, like mindfulness and gratitude, can make us happier—as does letting go of less healthy patterns like grudges and stressful thinking. With award-winning professor Dacher Keltner as your host, you can learn how to incorporate these science-backed strategies for happiness into your own life.

7 Timeless Facts About Paul Rudd

Younger fans may know Paul Rudd as Ant-Man, one of the newest members of the Marvel Cinematic Universe. However, the actor has been a Hollywood mainstay for half his life.

Rudd's breakout role came in 1995’s Clueless, where he played Josh, Alicia Silverstone's charming love interest in Amy Heckerling's beloved spin on Jane Austen's Emma. In the 2000s, Rudd became better known for his comedic work when he starred in movies like Wet Hot American Summer (2001), Anchorman (2004), The 40-Year-Old Virgin (2005), Knocked Up (2007), and I Love You, Man (2009).

It wasn’t until 2015 that Rudd stepped into the ever-growing world of superhero movies when he was cast as Scott Lang, a.k.a. Ant-Man, and became part of the MCU.

Rudd has proven he can take on any part, serious or goofy. More amazingly, he never seems to age. But in honor of (what is reportedly) his 50th birthday on April 6, here are some things you might not have known about the star.

1. Paul Rudd is technically Paul Rudnitzky.

Though Paul Rudd was born in Passaic, New Jersey, both of his parents hail from London—his father was from Edgware and his mother from Surbiton. Both of his parents were descendants of Jewish immigrants who moved to England from from Russia and Poland. Rudd’s last name was actually Rudnitzky, but it was changed by his grandfather.

2. His parents are second cousins.

In a 2017 episode of Finding Your Roots, Rudd learned that his parents were actually second cousins. Rudd responded to the discovery in typical comedic fashion: "Which explains why I have six nipples." He also wondered what that meant for his own family. "Does this make my son also my uncle?," he asked.

3. He loved comic books as a kid.

While Rudd did read Marvel Comics as a kid, he preferred Archie Comics and other funny stories. His English cousins would send him British comics, too, like Beano and Dandy, which he loved.

4. Rudd wanted to play Christian in Clueless. And Murray.

Clueless would have been a completely different movie if Rudd had been cast as the suave Christian instead of the cute older step-brother-turned-love-interest Josh. But before he was cast as Cher’s beau, he initially wanted the role of the “ringa ding kid” Christian.

"I thought Justin Walker’s character, Christian, was a really good part," Rudd told Entertainment Weekly in 2012. "It was a cool idea, something I’d never seen in a movie before—the cool gay kid. And then I asked to read for Donald Faison's part, because I thought he was kind of a funny hip-hop wannabe. I didn’t realize that the character was African-American.”

5. His role model is Paul Newman.

In a 2008 interview for Role Models, which he both co-wrote and starred in, Rudd was asked about his real-life role model. He answered Paul Newman, saying he admired the legendary actor because he gave a lot to the world before leaving it.

6. Before he was Ant-Man, he wanted to be Adam Ant.

In a 2011 interview with Grantland, Rudd talked about his teenage obsession with '80s English rocker Adam Ant. "Puberty hit me like a Mack truck, and my hair went from straight to curly overnight," Rudd explained. "But it was an easier pill to swallow because Adam Ant had curly hair. I used to ask my mom to try and shave my head on the sides to give me a receding hairline because Adam Ant had one. I didn’t know what a receding hairline was. I just thought he looked cool. She said, 'Absolutely not,' but I was used to that."

Ant wasn't the only musician Rudd tried to emulate. "[My mom] also shot me down when I asked if I could bleach just the top of my head like Howard Jones. Any other kid would’ve been like, 'F*** you, mom! I’m bleaching my hair.' I was too nice," he said.

7. Romeo + Juliet wasn’t Rudd's first go as a Shakespearean actor.

Yet another one of Rudd's iconic '90s roles was in Baz Luhrmann's Romeo + Juliet, but it was far from the actor's first brush with Shakespeare. Rudd spent three years studying Jacobean theater in Oxford, England, and starred in a production of Twelfth Night. He was described by his director, Sir Nicholas Hytner, as having “emotional and intellectual volatility.” Hytner’s praise was a big deal, considering he was the director of London's National Theatre from 2003 until 2015.

Born in New York City in 1858, Theodore Roosevelt grew up to become an influential politician and conservationist. He was also one of the most quotable figures in our nation’s history.

“I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of toil and effort, of labor and strife; to preach that highest form of success which comes, not to the man who desires mere easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph.”

These questions do not relate only to the next century or to the next generation. One distinguishing characteristic of really civilized men is foresight; we have to, as a nation, exercise foresight for this nation in the future; and if we do not exercise that foresight, dark will be the future!”

—From Outdoor Pastimes of an American Hunter, 1905

9. On His Fighting Style

“Don't hit a man at all if you can avoid it, but if you have to hit him, knock him out.”

—From a speech given in Cleveland in 1916

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."

—From the speech “Citizenship in a Republic," a.k.a. "The Man in the Arena” given in 1910

“Death is always and under all circumstances a tragedy, for if it is not, then it means that life itself has become one.”

—From a letter to Cecil Spring-Rice from 1900
