Why Love Needs Space: Applying the Benjamin Franklin Effect to Romantic Relationships

By:

Empirical evidence for the healthy push-and-pull of love.

You may recall the Benjamin Franklin Effect — that odd phenomenon of reverse psychology wherein doing someone a favor makes us like the person more. In this short “science experiment,” complete with a mandatory lab coat, the folks at SoulPancake set out to apply the Founding Father’s insight to the realm of romantic relationships. Though the task itself may appear silly and the quantitative finding hardly earth-shattering, beneath it lies a bigger and rather important qualitative point about the push-and-pull of a healthy relationship, one that resonates with the Chinese notion of wu-wei:

Make sure you allow room in the relationship for the other person to also give it back and invest in you. So maybe don’t insist on paying the bill every time or driving to their place every time. Give them a shot to invest and put just as much into it as you do. Whether you’re trying to get into a relationship or deeper into a long-term one, give your partner a chance to contribute to it.

Pair with a deeper look at the psychology of the Benjamin Franklin Effect, then see the science of how “positivity resonance” shapes love.

Why There Was No First Human

By:

“It’s just like how you used to be a baby and now you’re older, but there was no single day when you went to bed young and woke up old.”

We live in a culture where 40% of people don’t believe the world is more than 6,000 years old. And yet how can an intelligent being hold such beliefs when faced with a 13,000-year-old eucalyptus tree or an 80,000-year-old aspen? But even when we embrace science completely, one of the most baffling aspects of the timeline of evolution — for creatures as dependent on categories as we are to make sense of the world — is its incremental progress largely devoid of clear markers denoting when one primitive species ends and its evolved successor begins.

Inspired by The Magic of Reality: How We Know What’s Really True — Richard Dawkins’s children’s book seeking to replace myth with science — PBS’s Joe Hanson offers a concise and elegant explanation of why there was no “first human.” Tracing any one person’s family tree — yes, yours, as well as mine — back 185 million generations takes us not to another human but to a fish, which begs the question of where the human species “began”:

You can never pinpoint the exact moment when a species came to be — because it never did. It’s just like how you used to be a baby and now you’re older, but there was no single day when you went to bed young and woke up old… Evolution happens like a movie, with frames moving by both quickly and gradually, and we often can’t see the change while it’s occurring. Every time we find a fossil, it’s a snapshot back in time, often with thousands of frames missing in between, and we’re forced to reconstruct the whole film. Life is what happens in between the snapshots.

The Timekeeper: Behind the Scenes of Humanity’s Most Accurate Atomic Clocks, Which Dictate Our Daily Lives

By:

“Time is a coordinate that lets us most simply understand the evolution of the universe.”

Since the beginning of human existence, we have sought to understand time, to map it, to hack it, to standardize it, and to perfect our bodily experience of it. We have turned it into our civilization’s greatest meme and have probed it with our most unrelenting scientific rigor. Today, time not only dictates the rhythms of our daily lives but is also at the center of our digital universe — and yet it remains largely misunderstood by us lay people.

In this fascinating micro-documentary, Dr. Demetrios Matsakis, chief scientist for Time Services at the U.S. Naval Observatory — the same federal agency that hired astronomer Maria Mitchell as the first woman employed by the government — takes us on a tour of the USNO’s 100 atomic clocks, where the time on your iPhone originates. Dr. Matsakis explains how these atomic clocks — which won’t fall behind or race forward by a single second in 300 million years, rendering them the most accurate measuring devices ever created by humanity — also synchronize GPS, coordinate military operations, dictate financial transactions, and orchestrate internet communication. He then peers into the future to imagine the time-accuracy that is to come, as well as the dark side of such precision.

Time is a coordinate that lets us most simply understand the evolution of the universe.

[…]

In one sense, we’ve figured out everything from a practical point of view — the fundamentals — and in another sense, we don’t know anything at all… There are people who say time could stop, time could have a beginning, time is a derived quantity and not a fundamental quantity, and those are things I can’t give answers to. It’s something like being a doctor who may know how to keep someone alive, but doesn’t know what life is. I know how to compute the second — that’s my job.

Complement it with Dan Falk’s excellent In Search of Time: The History, Physics, and Philosophy of Time, a fine addition to these 7 excellent books about time, then revisit the curious psychology of why we experience time as elastic.
