Why Do Clocks Go Clockwise? | Atsuko Okatsuka Asks Hank Anything

Overview

Hank Green and comedian Atsuko Okatsuka team up for “Ask Hank Anything,” an interview where Atsuko asks Hank questions and Hank answers with science/history while Atsuko reacts with comedy and candid thoughts. The episode blends playful banter, surprising existential detours, and mini-lessons—often using props.

Main beats & standout moments

• Quirky opener + disaster humor: They bond over Atsuko’s experience performing during an earthquake, followed by meme-worthy reactions from people in other disaster contexts (volcanoes, hurricanes). Atsuko jokes about the “real tell” of an earthquake being the swaying chandelier, and they riff on the absurdity of a chandelier living in a comedy club—turning “put me in a basement…” into a running gag.
• Existential question spirals: Atsuko reveals she received very intense questions in advance but didn’t recognize them, sparking a deeper discussion about asking questions, the self, and even her eyebrows “vanishing” during Santa Ana winds.

Big science/history explanations (with jokes)

1. Why clocks go clockwise

• Hank explains the “clockwise” direction via geography: many inventions formed in the Northern Hemisphere, where sundials cast shadows that visually move in a way that aligns with clock motion.
• Hank brings a sundial prop; Atsuko jokes that holding it makes her look like a “colonizer.”
• Twist: if clocks/sundials had instead been invented in the Southern Hemisphere, the direction could plausibly have been counterclockwise—“majority wins.”

2. Why Americans refrigerate eggs (but other places don’t)

• Hank offers a straightforward biology explanation: eggs have a protective bloom/cuticle coating.
• In the US, chickens aren’t consistently vaccinated against salmonella, so eggs are often washed, removing the protective layer—meaning refrigeration becomes necessary.
• In much of Europe, vaccination helps eggs retain the cuticle, reducing the need for refrigeration (with added complexity around condensation if chilled eggs aren’t kept consistently cold).

3. Why people clink glasses when toasts

• Hank questions single “definite” explanations—whether they relate to poison testing, shaking hands to show no weapons, or etiquette-sense theories.
• The conversation lands on a meta-point: history is often interpreted through violent moments, but we should remember rituals may persist simply because they feel good.

4. Why the US measures differently

• Hank traces measurement differences to historical fragmentation, royal standards, and later industrialization pushing standard systems.
• He contrasts the UK/imperial system with France’s metric system (decimal-friendly vs awkward conversions).
• A “Future Hank” add-on explains the US didn’t fully switch due to politics and relations with France—including Jay’s Treaty and quasi-war tensions—making French-linked standards harder to adopt.
• Atsuko closes the thought by framing these differences as more than practical—they also reflect cultural isolation.

Relationship/personality talk

Self-expression, confidence, and “what you don’t like”

• Rehearsed authenticity: They discuss whether rehearsing makes performance less “authentic.” Hank argues that rehearsal helps you express your true self well, not fake improvisation in life.
• Confidence vs insecurity: Atsuko reflects on how comedic confidence can appear solid while secretly being fragile—confidence can flip quickly if she senses she’s losing the audience.
• Reward loops & boundaries: They explore why people keep doing things they don’t want because they’re rewarded for them, and how it can be difficult to identify personal boundaries.
• Atsuko shares her social comfort “type”: she’s more bar/talking-focused than club/game-night focused, and she jokes about inviting people over only for the games never to come out—resulting in “friend juice” instead.

Ending

After answering all questions, Atsuko plugs her Hulu/Disney+ special “Father” and shares social handles. They finish with warm gratitude, a final joke about the episode being over—tied to an “empty pelican” prop.
