A few days earlier…
“Mommy,” said Eve sadly. “Can you get me a doll?”
“Honey,” Pauline gently replied. “You know we’re on a tight budget this month. Mommy will buy you one next month. That’s a promise.”
“But mommy…” Eve’s voice began to crack. “My birthday is in two days. Did you forget about it?”
“Oh, no, no, sweetheart! Not at all!” Pauline said, but she had actually forgotten and felt terrible about it.
“Are you still not going to get me a doll? I don’t have any friends, mommy. Nobody wants to be friends with me because we are poor. That doll can be my best friend…”
“Oh honey,” Pauline hugged Eve. “I will get you the doll. Promise. Don’t be sad, ok?”
Pauline knew the kids at Eve’s school didn’t treat her well because she wasn’t as rich as them, but there wasn’t much she could do about it. Children can be cruel at times.
Present day…
Pauline was delighted after buying the doll. She couldn’t wait to give it to Eve and see her beautiful smile. The doll was one of those vintage kinds, holding a tiny baby in her arms.
“Oh, Eve will be so happy!” Pauline thought on her way back home.
And Eve was. The little girl’s joy knew no bounds when Pauline showed her the doll on her birthday.
Sometimes, the cause of someone’s smile is the source of another person’s grief.
“Ta-da! Mommy got the doll for Evie!” Pauline exclaimed, holding the doll in her hands. “Can mommy have a kiss for that?”
“It’s so pretty! Thank you, mommy!” Eve chirped as she kissed Pauline on the cheek.
As Pauline handed over the doll to Eve, she suddenly heard a strange crackling sound.
“What was that?” Pauline wondered.
She shook the doll, holding it close to her ears, and heard the crackling again.
“Mommy! Give it here! I wanna hold my doll! Please! Please!” Eve said, excited to play with it.
“One second, honey. I think there’s something in here…”
It was then that Pauline examined the doll and found a secret pocket sewn into the doll’s outfit. She undid the loose threads around it, and a note fell from it.
Eve quickly picked it up and said, “Mommy, it says, ‘Happy Birthday, Mommy.’ It’s not your birthday! It’s my birthday! This is so silly!”
When Pauline read the note, she noticed the message seemed like it was scribbled by a child. At that point, the thought of the woman selling the doll flashed through Pauline’s mind.
The next day, she returned to the flea market with the doll, and luckily, the woman’s stall was still there.
“Oh, I’m glad I found you here!” Pauline said. “I bought this doll yesterday, and I found a note inside…”
When the woman, Miriam, saw the note, her eyes welled up. “My daughter got this doll for me,” she said quietly. “She passed away two days before my birthday…My husband and I, oh, I’m sorry…” The woman covered her face as her tears started to flow.
“I’m really sorry for your loss,” Pauline said apologetically. “I had no idea. I know I can’t take away your pain, but if it helps, I can give you a hug.”
“Oh, thank you…” Miriam said. Pauline gave her a warm hug, after which Miriam revealed her sad story, which brought tears to Pauline’s eyes.
“My little daughter was diagnosed with cancer,” Miriam said. “We needed money for her chemotherapy. My husband and I work at a factory. We didn’t have enough money to cover her hospital bills, so we set up a stall here to sell our old furniture and things we didn’t need.”
“But we couldn’t save our daughter…She—she left us too soon. We’re selling her toys because every time I look at them, it just makes me sad.”
“One night, when I held my baby girl’s hand, she asked me to be happy. She had said, ‘Mumma, when I’m gone, please remember me with a smile.’ So I decided to sell the toys. She had bought that doll, saying it would remind me of her. I’m sorry I feel like I’m oversharing with you, but my heart feels really relieved today. Thank you for listening to me.”
As Miriam finished, she broke down into tears again. Pauline consoled her, and the two women talked about their lives for a while. Pauline told her how she’d been raising Eve by herself and invited her over to spend time with them.
“Eve will love to meet you,” she said. “And thank you so much for the doll. It made my daughter’s day. I’m sure your daughter is looking at you and smiling. Thank you again,” she added before she left.
A few days later, Miriam visited Eve and Pauline at the trailer where they lived.
“This is in appreciation of your kind heart and patience in listening to me that day. I hope this helps you and Eve,” Miriam said, handing Pauline an envelope.
When Pauline opened it, she found a couple of dollar bills inside. $3000 in total. “Oh, Miriam, we can’t take this. This is a lot. No, no, this doesn’t feel right…”
“You can take it, Pauline,” Miriam insisted. “A mother’s heart knows how much it hurts when you can’t do enough for your child. We made this by selling the toys. Please keep it. If not for my sake, please keep it for Eve’s sake.”
Pauline cried. “Oh, Miriam, thank you. This will help us a lot. Thanks.”
From then on, Miriam and Pauline became friends, and Miriam loved and spoiled Eve too much. But the best part was that Pauline and Eve’s company helped Miriam heal and move on from her loss.
What can we learn from this story?
Help someone in need, and you’ll never regret it. Pauline and Miriam helped each other in whatever way they could. That helped Miriam overcome her grief, and Pauline and Eve found someone who cherished their company.
Sometimes, the cause of someone’s smile is the source of another person’s grief. Sadly, the doll which made Eve happy on her birthday was a reminder of Miriam’s sad past.

Synaptic Information Storage Capacity Measured With Information Theory
Ever wondered just how much data your brain can hold? We often compare the brain to a supercomputer, but what if that comparison isn’t just a metaphor—it’s literal? Deep within your brain, at the junctions where neurons meet, lies an extraordinary form of biological storage: the synapse. And thanks to breakthroughs in information theory, we’re beginning to quantify its staggering capacity.
In this article, we’ll dive into how synaptic storage works, how scientists measure it, and why this knowledge could shape the future of data storage—from artificial intelligence to DNA-based memory.
What Are Synapses and Why Are They Important?
Think of neurons as the brain’s messengers. But without synapses—the gaps between them where signals are transmitted—those messages would go nowhere. A synapse is where the magic happens: it’s the space where one neuron sends a chemical or electrical signal to another, sparking thoughts, memories, movements, and more.
Now here’s the kicker: each of these tiny junctions doesn’t just pass along data—it stores it.
Your brain has about 86 billion neurons, and each one can form around 1,000 synapses. That’s a total of roughly 125 trillion synapses buzzing away in your brain, constantly sending and receiving signals. These connections form the foundation of your memories, knowledge, and perception.
Measuring Synaptic Storage with Information Theory
To understand how synapses store information, scientists turn to information theory—a branch of mathematics that deals with encoding, decoding, and compressing data. Think of it like analyzing how much a hard drive can hold, but on a biological scale.

Each synapse, as it turns out, can store up to 4.7 bits of information. That might not sound like much until you consider the scale:
- 1 bit is a single piece of binary data (a 0 or 1)
- 4.7 bits per synapse × 125 trillion synapses = over 500 trillion bits of potential storage
Translated into digital terms, your brain can theoretically store more data than the entire internet—all in a compact, low-energy package powered by biology.
The Brain’s Efficiency: Powering Trillions of Connections
Here’s something even more mind-blowing: while your laptop heats up and guzzles electricity, your brain handles all of this complex storage and processing using roughly 20 watts of power—that’s about the same as a dim light bulb.
This insane efficiency is what’s inspiring researchers to build neural networks and deep learning systems that mimic the brain. If computers could process and store data like synapses do, we’d have faster, smarter, and greener technology.
Artificial Intelligence and Synaptic Models
The field of AI, especially machine learning and deep learning, borrows heavily from how the brain processes and stores information. Artificial neural networks use layers of interconnected nodes (inspired by neurons) to simulate learning.
But here’s where it gets interesting: researchers are now using real data about synaptic information capacity to refine these systems. The goal? To build AI models that are more human-like, not just in intelligence but in efficiency and adaptability.
Imagine a future where your smartphone thinks and stores information with the same elegance as your brain. That future isn’t science fiction—it’s science.
Beyond the Brain: DNA as the Ultimate Storage Device
While the brain remains the pinnacle of biological storage, it’s not the only game in town. Enter DNA, nature’s original information vault.
DNA doesn’t just code for life—it can be used to store digital data. And we’re not talking small files here. A single gram of DNA can hold up to 215 petabytes of data. That’s 215 million gigabytes—enough to store every photo, song, and document you’ve ever owned, plus millions more.
In fact, researchers have already done it. In one groundbreaking study, scientists encoded a 52,000-word book into synthetic DNA. They converted the digital content into binary (0s and 1s), then translated those digits into DNA’s four-letter alphabet: A, T, G, and C. The result? A physical strand of DNA holding a complete, retrievable digital file.
Why DNA Storage Matters for the Future
Traditional storage devices—hard drives, SSDs, even cloud servers—have physical limits. They degrade over time and take up massive amounts of space. DNA, on the other hand, is incredibly compact, durable, and stable for thousands of years if stored properly.
If scaled correctly, DNA storage could revolutionize how we preserve knowledge. Imagine backing up the entire contents of the Library of Congress on something no bigger than a sugar cube. That’s the level we’re talking about.

Bridging Biology and Technology
What’s exciting is how these two areas—brain synapses and DNA storage—are starting to intersect. Both are nature’s proof that small-scale systems can handle mind-blowing amounts of data. As scientists continue to decode these systems using information theory, they’re finding ways to integrate them into technology.
It’s not about replacing computers with brains or turning DNA into a USB drive. It’s about learning from nature’s most efficient designs to build the next generation of computing and storage systems.
Conclusion: Reimagining Storage in a Biological World
Your brain’s 125 trillion synapses silently store and process more information than entire server farms, all while sipping on 20 watts of energy. Meanwhile, DNA—the code of life—is showing us how to pack massive libraries of data into microscopic strands.
By measuring synaptic storage capacity with information theory, we’re not just understanding the brain better—we’re laying the foundation for a new era of intelligent, efficient technology.
The takeaway? Nature has already solved problems we’re only beginning to understand. And the more we study it, the closer we get to unlocking the true potential of both our minds and our machines.
