Chances are, you think you do. It’s ubiquitous and iconic. How could you not know it?
But when tested, it turns out very few people can remember all the features of the logo. One study of 85 people found that only about half could pick the correct logo out of a lineup of similar ones. And only one person could correctly draw it.
This isn’t an isolated example. A classic study from 1979 found that people similarly couldn’t draw a penny accurately or pick out a correctly drawn penny from incorrect ones.
People aren’t just bad at remembering things they see all the time, but also in actually knowing how they work. In a 2006 study, many people made significant errors when drawing a bicycle, like putting the chain around the front wheel as well as the back wheel. More than just a forgotten detail, putting the chain around both wheels shows a deeper misunderstanding of how a bicycle works. A bicycle with a chain around both wheels wouldn’t be able to turn.
It turns out people’s knowledge of how the world works is often fragmented and sketchy at best. They systematically overestimate their understanding of everyday devices and natural phenomena. People will tend to give themselves high ratings on how well they understand something, such as how bicycles or zippers work. But when they’re asked to actually explain the mechanics of these objects, their ratings of their understanding typically drop.
Just like how your knowledge of the world around you is imperfect, your knowledge about your own knowledge – also called metaknowledge – is often flawed. My field of cognitive science has been uncovering various gaps in human metaknowledge for decades.
If people are systematically overconfident about how well they understand things, why don’t they notice when they don’t understand something? And what can people do to better recognize the limits of their own knowledge?
Why you think you know more than you do
Researchers have identified several factors behind people’s overconfidence in their knowledge.
One is that people confuse environmental support with understanding: The information is out in the world but not actually in your head. With a bicycle or a zipper, all of the parts are visible to you, and you may confuse this transparency for an internal understanding of how they work. But until you go to use that knowledge by attempting to explain how they work, you may not recognize that you don’t understand how those parts interact.
A second factor is confusing different levels of analysis. People can often describe how something works at a very high level. You know that the engine of a car makes the car go, and the brakes slow and stop the vehicle. But confidence in your high-level understanding of the car may bias you to think you also have a good grasp of the finer details, like how the engine pistons and brake pads work.
Additionally, people can be blind to the ways their knowledge shapes their own perception. In one study, researchers had participants tap out the tune to a popular song. On average, the tappers thought listeners would be able to identify the song about 50% of the time. But when listeners had to identify the tapped song, they actually could identify it only 2.5% of the time. The tappers didn’t realize how much their knowledge was making identifying the song seem easy to them.
This disconnect has consequences beyond whether someone else can understand your Morse code version of a song. When teaching people, whether in formal classroom settings or through casual mentorship, you can sometimes have an expert blind spot: the inability to recognize the difficulties beginners face when learning something you have expertise in.
Building expertise often involves internalizing knowledge to the point where it becomes invisible to you. You draw on knowledge you don’t realize you have, making it hard to relate to learners who lack this knowledge – and, of course, hard for learners to relate to your teaching. You might have experienced this when you’ve gotten partway through explaining something, only to realize you’ve been using jargon you forgot isn’t common knowledge and lost your listener.
How to address metaknowledge failures
Your metaknowledge can fail in two directions: You can think you know more than you do, and you can be blind to how much you’re relying on knowledge you do have. Each calls for a different response to correct it.
When you’re overconfident in your knowledge, the remedy is using that knowledge. You’ll quickly realize how much you actually understand and dial down your confidence. Challenging yourself to actually try to walk through how something works is a great exercise in intellectual humility – that is, recognizing that you may be wrong – and can keep you from getting out over your skis.
Building a greater appreciation for what you know is more difficult. You can’t simply unlearn what you’ve internalized. But what this challenge shows is that, to some extent, knowing a subject and knowing how to teach it are two separate skills. Some experts are great teachers, but not simply by virtue of being experts. Recognizing that you have to approach teaching with humility, and that your expertise doesn’t automatically make you a skilled teacher, can go a long way toward making you a better teacher and mentor.
These aren’t easy and quick fixes to failures of metaknowledge. Both require ongoing intellectual humility and a willingness to distrust your own confidence. But acknowledging the fallibility of your own metaknowledge is a good place to start.
This article is of particular interest for me. Because a few years ago, I had a biking accident at the local Merlin (OR) rail crossing. I banged my head badly and was unconscious for about eight minutes. Later on the surgeon who operated on my head said that I was lucky to be alive but that from here on my memory would be poor.
I work very hard to try and remember the items that I want to. And without my pocket book to write things down, I would be so much more forgetful.
The astronauts on Artemis II’s trip to the Moon in April 2026 didn’t just have an amazing journey through space. They also saw something extraordinary. They were the first humans to see a total solar eclipse from space.
From Earth, the circle of the Sun is about the same size as the circle of the Moon. With the bright circle blocked, you can see the undulating rays of the Sun’s corona, or outer atmosphere, that are normally too dim to be observed.
During my second total eclipse, the period of totality – that short span when you can remove your protective glasses and look directly at the eclipse – lasted close to 4 minutes. I saw waves of diffuse light snaking around an ink-black hole in the sky. It looked very wrong – almost alien.
On Aug. 12, 2026, there will be another total solar eclipse, visible only from Greenland, Iceland, Spain and the Balearic Islands of the Mediterranean. Some fortunate viewers in Spain and nearby islands may see the eclipse just before sunset, low on the horizon. The Moon illusion, a phenomenon where the Moon looks bigger when it’s near the horizon, might make this eclipse look unusually large.
Unusual eclipse perspectives
Astronauts will occasionally also have less common eclipse experiences. I interviewed one I call by the pseudonym “Jackie” in my research about astronauts’ experiences of awe. She was part of an astronaut training group that did a flight exercise during a total solar eclipse.
Jackie and her squad flew their jets in the shadow of the Moon. This lengthened their time in totality because they could follow and stay within the shadow. Jackie was most impressed with how the Sun’s corona seemed to shift and ripple.
“It’s not static … it’s alive,” she told me.
On April 6, 2026, the astronauts of NASA’s Artemis II mission saw another kind of unusual eclipse as they flew around the Moon. At one point during their flight, the Moon and the spacecraft aligned so that the Moon was directly between them and the Sun, blocking the Sun’s disk in a way that looks very different from what we see on Earth.
The astronauts were so close to the Moon that the Moon looked bigger than the Sun and hid more of its bright circle. Earth was also in view, and sunlight reflected from the Earth onto the Moon in a phenomenon NASA calls “earthshine.” This dim light is very similar to the moonlight that shines on the Earth at night.
Imagine the Sun hidden behind the Moon, creating a hazy halo around the Moon’s edges. At the same time, faint light reflected from Earth softly illuminates the Moon, revealing mountains and craters in a dim twilight. Now imagine this striking scene lasting 54 minutes.
This sight was, without a doubt, one of the most unusual eclipses ever seen by human eyes.
Although Artemis’ astronauts are trained to think scientifically, this experience propelled them into a state of awe. They talked openly about how their brains were “not processing” what they observed. While NASA kept them busy with a variety of tasks, the sound of emotion and excitement in their voices as they broadcast live from their lunar flyby was unmistakable.

One astronaut said she gained an awareness of the fragility of our planet that now shapes everything she does, while another described becoming more curious after returning to Earth. A third said the awe he experienced in lunar orbit changed his understanding of time and infinity.
Space travel creates many opportunities for awe, but a solar eclipse from behind the Moon, as Mission Commander Reid Wiseman put it, required “20 new superlatives.”
It’s an experience most of the earthbound eclipse-chasers heading to Greenland or Iceland or Spain this summer will only dream about. Whether eclipses happen in space or on Earth, though, close encounters with the grandeur of our universe can make you feel profoundly human.
In this difficuly world at present, this is a perfect article. As was written, “…. the awe he experienced in lunar orbit changed his understanding of time and infinity.“
During the week of the 20th to 24th April, 2026, BBC Radio 4, immediately after the World At One, at 13:45-14-00 BST, presented a fifteen-minute series on death. The episode of the April 22nd, 2026 was called Lay This Body Down. It is summarised as follows:
As our society becomes more secular, more people feel like they want to do death their own way. That’s leading to a range of new options for disposing of dead bodies.
Now watch this:
Jean and I have opted for human composting after we have died. It is a natural process and details may be found here.
In early April 2026, the Artemis II mission captivated me and millions of people watching from across the world. The crew’s courage, skill and infectious wonder served as tangible proof of human persistence and technological achievement, all against the mysterious backdrop of space.
People back on Earth got to witness the mission through remarkable photos of space captured by astronauts. Images created and shared by astronauts underscore how photography builds a powerful, authentic connection that goes beyond what technology alone can capture.
As a photographer and the director of the Rochester Institute of Technology’s School of Photographic Arts and Sciences, I am especially drawn to how these photographs have been at the center of the public’s collective experience of this mission.
In an era when image authenticity is often questioned and with the capabilities of autonomous, AI-driven imaging, NASA’s choice to train astronauts in photography has placed meaning over convenience and prioritized their human perspectives and creativity.
Capturing space from the crew’s perspective
Photography was not originally placed as a high priority in NASA’s Apollo era. The astronauts only took photographs if they had the chance and all their other tasks were complete.

This excitement could be explained by the novelty of photos from space, but these images also distinguish themselves as products of astronauts experiencing these sights and interpreting them through their photographs. These differences require an important distinction around where technology ends and humanity begins.

Human perspective versus AI tools
Photography has long integrated AI-powered software and data-driven tools in a variety of ways: to process raw images, fill in missing color information, drive precise focus and guide image editing, among others. These modern technological assists help human photographers realize their vision.
And AI can generate convincing, realistic images and videos from nothing more than a text prompt, using readily available tools.
Researchers train AI to mimic patterns informed by millions of sample images, and the algorithm can then either take or create a photograph based on what it predicts would be the most likely version of a successful, believable image.
Human-created photos are rooted in direct observation, intent and lived experience, while AI images – or choices made by AI-driven tools – are not. While both can produce compelling and believable visuals, the human photographs carry emotional power because the photographer is drawing from their experiences and perspective in that moment to tell an authentic story.
Artemis II photographs resonate, not only because they are historic, but because they reflect the deliberate choices and intent of a human being in that specific moment and context. The exposure, camera setting, lens choice and composition are all dictated by the astronaut’s vision, skill, perspective and experience. Each image is unique in comparison with the others. These choices give the images narrative power, anchoring them in human perspective.

Images to tell a story
Photographers choose what to include in the final version of their image to tell a story. In the Artemis II images, this human perspective comes out. In the “Earthset” photo, you see a striking juxtaposition of the Moon’s monochromatic, textured surface in the foreground against a slivered, bright Earth.
The choice to include both in the frame contrasts these objects literally and figuratively, inviting comparison. It creates a narrative where Earth is contrasted against the Moon – life is contrasted against the absence of it.
Another photo shows the nightside of the whole Earth, featuring the Sun’s halo, auroras and city lights. The choice to include the subtle framing of the window of the capsule in the lower left corner reminds the viewer where and how this image was captured: by a human, inside a capsule, hurtling through space. That detail grounds the photograph in the human perspective.
Both photos are reminiscent of Earthrise and the Blue Marble. These past images hold a place in the global collective consciousness, shaped by a shared historical moment.
The Artemis II photographs are anchored in this collective moment of lived human experience, yet also shaped by each astronaut’s viewpoint. The crew’s unique perspectives exemplify photography’s transformative power by inviting viewers to engage emotionally and intellectually with their journey. These photographs share the astronauts’ awe and wonder and affirm the value of human creativity and its ability to connect us in a captured moment.
I am going to repeat a sentence towards the end of the article: “These past images hold a place in the global collective consciousness, shaped by a shared historical moment.”
Amazingly, Jean and I were being run recently in to somewhere local and Trevor, our driver, was listening to a talk by David Eagleman. I was captivated.
In that talk David Eagleman spoke about Roger Penrose and his research into consciousness. Here’s an AI summary:
Roger Penrose proposes that human consciousness is non-computational and originates from quantum processes within brain neurons, rather than just neural connections. Together with anesthesiologist Stuart Hameroff, he developed the “Orchestrated Objective Reduction” (Orch OR) theory, which suggests consciousness arises from quantum computations in microtubules.
Roger Penrose is the author of The Emperers New Mind.
Thus, beyond the eighty-six billion neurons that make up the brain, there are also the microtubals. These are very small and the diameter of several thousand of them are less than the diameter of the human hair. See WikiPedia.
“The brain has deep purpose” was one of the sayings Eagleman spoke of. “Why do we have experience” was another.
There was much more that I did not really understand. But it was still fascinating.
Then we discovered that what Trevor was listening to was also a video. The video is Inner Cosmos. It runs for 75 wonderful minutes.
Here is that video.
To say that this has absolutely updated my mind to a newer level is an understatement; big time!
This past January, a man was walking through Onancock, Virginia, when he noticed a suspicious object outside Historic Onancock School, a local community center.
The man approached the object — a large black bin labeled “Family Dollar” — and carefully lifted the lid to see what was inside. There, wriggling against each other in the tight space, were eight 10-week-old puppies.
The puppies were weak, defenseless and clearly needed help. The man drilled air holes in the lid of the box and eventually contacted Eastern Shore Regional Animal Control Facility for help.
Tragically, one puppy passed away before rescuers could assist. The others quickly relaxed into the capable hands of animal control staff.
According to Eastern Shore Regional Animal Control Facility shelter manager Jeri Winn, it’s common to find puppies dumped along the Eastern Shore, but significantly less common in Onancock, a bustling seaside town.
Though she’d seen plenty of cases like this, Winn still felt a familiar sadness as she admitted the puppies into care. Despite everything, she was grateful that the pups were finally in a safe place.
“All we can be thankful for [is that] whoever left them realized they were in a good location to be seen,” Winn told The Dodo.
Team members transferred the puppies to Critters 4 U Rescue, an animal shelter and foster organization. Rescuers determined the puppies were Australian shepherd mixes, and they named them after the seven dwarfs — Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy and Dopey.
One pup has already been adopted, and the others are still safe at Critters 4 U Rescue, waiting to meet their forever families.
Eastern Shore Regional Animal Control Facility is grateful for Critters 4 U Rescue, along with all the other rescues who offered to help these needy pups find the homes they deserve.
“We are so grateful for every rescue that reached out,” Eastern Shore Regional Animal Control Facility wrote in a Facebook post. “In moments like this, our small shelter is reminded just how much we rely on the compassion and partnership of rescue organizations who step up without hesitation.”
There was something really special about the last full moon. We watched as the moon rose on the very early nights of February, 2026 and I wished I had taken some photos. But no problem as YouTube had captured the images of the moon taken by others.
The Snow Moon in 2026 was the full moon that lit up the night sky on February 1, 2026, reaching its peak illumination around 5:09 p.m. EST (around 22:09 UTC) that evening. Because the moon appears full for a couple of nights around that moment, it was visible as a bright, full lunar disk on the nights of February 1 and 2. It’s traditionally called the “Snow Moon” because February is usually one of the snowiest months in the Northern Hemisphere. Here are some gorgeous images from our talented community of photographers. Enjoy them!
Of my three cycle rides a week, about once a week I turn left on Hugo Road, rather than turning right. After a very few miles I then turn right onto Three Pines Road. Less than a mile further on I pass a sign that speaks of our neighbourhood.
For those that live in this area are the friendliest Jeannie and I have ever known. And we are not the only ones to know this, as you will see from the following photos.
oooo

What the precise area is and why the locals are so, so friendly is beyond us. But to say we are grateful is an understatement. As the sign says:
