Fascinating!
Retired engineer discovers 55-year-old bug in Lunar Lander computer game code | Ars Technica:
As mentioned in the quote above, the root of the problem was a simple computational oversight—a missing division by two in the formula used to calculate the lander’s trajectory. This seemingly minor error had big consequences, causing the simulation to underestimate the time until the lander reached its lowest trajectory point and miscalculate the landing.
It’s fascinating to me that we can peer up through our thick and whiriling sea of gasses above us that we call our atmosphere and peer into the far reaches of our solar system to capture images of Jupiter’s moons and their surface activity here from the surface of our own planet.
Thanks to the amazing Phil Plait for the inspiration to look up today!
An amazing image of Io, Jupiter’s tortured hell-moon:
Yowza! All those blotches on it are volcanoes, many of which are active (Io is relentlessly squeezed by Jupiter’s immense tidal force, which create internal friction which melts the moon’s interior and cracks the outer layers, allowing that material to reach the surface). In fact the paper notes that the observations show some changes on the surface. The volcano Pele is the oddly shaped dark blob just below and to the right of center, surrounded by a red ring of erupted material. There are two volcanoes just to the right of it; the left one is Pillan Patera, and the scientists note that the red ring looks overlaid by newer lighter material right where Pillan sits. That’s likely from a powerful eruption that occurred in 2021.
Not that bioturbation was on your “To Think About” list for today… but you should think about bioturbation and its role in the larger biosphere. Fascinating stuff!
Mapping the seafloor sediment superhighway | YaleNews:
“Our analysis suggests that the present global network of marine protected areas does not sufficiently protect important seafloor processes like bioturbation, indicating that protection measures need to be better catered to promote ecosystem health,” Tarhan said.
Fascinating… now think of the implications in an era of deep fakes, AI, and ubiquitous access to information of all varieties at one’s choosing…
In this replication, which rigorously recreated the method and procedure of Wade et al. (2002), participants were interviewed over three interview sessions using free recall and imagery techniques about three true and one fictitious childhood event photos. The balloon ride was modified to a culturally appropriate target event – a Viking ship ride – to ensure that the doctored photograph was functionally equivalent. The results showed almost identical patterns in the two studies: 40% (n = 8) of the participants reported partial or clear false beliefs or memories compared with 50% (n = 10) in the original study. The participants who reported false memories reported detailed and coherent memory narratives of the Viking ship ride not depicted in the doctored photograph. Our study successfully replicating the results of Wade et al. (2002), suggest that memories can relatively easily be implanted, regardless of cultural setting.
I spent many hours reading Popular Science as a young person (and into college) in the high school library and sharing amazing stories with friends. I understand the business side of this, but it still feels to me like we’re losing something very valuable…
After 151 years, Popular Science will no longer offer a magazine – The Verge:
After 151 years, Popular Science will no longer be available to purchase as a magazine. In a statement to The Verge, Cathy Hebert, the communications director for PopSci owner Recurrent Ventures, says the outlet needs to “evolve” beyond its magazine product, which published its first all-digital issue in 2021.
Here are the “12 Problems” I’ve built my current life around. These are non-negotiables, and they are also the focus of everything I do. If a situation doesn’t fit into one of these problems, I’ll generally relegate it, delegate it, or ignore it.
I don’t generally recommend this practice for everyone. It’s a very difficult ethical standard to hold, and it can be cumbersome to run the mental math of “which problem am I trying to solve?” at any given time.
However, this approach’s clarity and focus far outweigh the negatives.
Here are my 12 Problems. I highly urge you to come up with your own:
How can I have a positive impact on this world?
How can I thrive while operating contrary to the dominant social or cultural trends?
How can I inspire young people to appreciate learning as a practice?
How do I provide for my family while remaining true to my calling?
How can I live with the most ethical sustainability while not sacrificing my enrichment in balance with the Creation?
How can I be the best role model for my espoused ideals and ethics as presented to my children and students?
How can I live according to nature (kata phusin in Stoicism)?
What does it mean to really be an effective teacher who can make connections and expand the worldview of my students?
How can I be a good Dad, and what does that mean?
How can I be a good partner, and what does that mean?
How can I explore my own self and brain and express that in my life?
How do I always maintain my own curiosity despite the challenges that the outside world might present?
I love incorporating paper airplanes into my classroom lessons on dynamics, flight, movement, gravity… the list goes on and on. They’re so applicable to so many scientific principles but also appeal to the curious nature inside all of us that loves to fold and learn…
History of the Paper Airplane: Paper Flight Technology Inspires Drones:
“The magic of a paper airplane is that all of these little flight corrections are happening continuously throughout its flight,” Ristroph says. “The plane is hanging under a vortex that is constantly swelling and shrinking in just the right ways to keep a smooth and level glide.”
Voyager 1 and 2 were launched in 1977 and have, by all expectations, exceeded their missions and then some. I was born in 1978, so I share some sentimental affinity with these two marvels of human engineering. Glad to see we reconnected with Voyager 2 after a few scary days there as it continues its incredible journey outside our solar system.
We’ll be in touch with the two Voyagers until they run out of their power reserves sometime in the 2030s. That will be a sad day. May we all contribute a verse to humanity’s story and the cosmos, much as these robots have done during their time!
I don’t think it’s a coincidence that my daughter was born on August 1, either 😉
NASA reestablishes full communications with Voyager 2:
Voyager 2 resumed communications with Earth after remaining silent for two weeks. At 12:29 a.m. EDT on Aug. 4, the spacecraft began returning science and telemetry data, indicating it is operating normally and remains on its expected trajectory, stated NASA.
If you ask almost any of us teachers what sort of skills or attitudes we’d love to see more developed in our students, you’d hear responses such as “resiliency” and “less anxiety.” In this first large-scale study of social and emotional learning approaches in k-12 education, Yale School of Medicine lays out some great findings (emphasis mine):
Students also showed improved social and emotional skills, attitudes, and behaviors, such as student self-efficacy, self-esteem, mindset, perseverance, and optimism, among others. Furthermore, the report confirmed that students who participate in SEL programs also feel better in school, reporting less anxiety, stress, depression, and suicidal thoughts. Students were also more connected and included and had better relationships with peers and teachers.
I always love working with my students to help them realize the really interesting nature of the Earth’s tilt (and wobble) and how it directly impacts our seasons rather than proximity to the Sun!
When Is Aphelion 2023 and What It Means – The New York Times:
But don’t expect any relief from summer. Seasons on Earth are the product of changes in the amount of direct sunlight as the planet tilts toward and away from the sun — not its orbital path. It would take a much greater swing, so that the amount of received sunlight dropped significantly, in order to notice the difference.
This has no bearing on your life and won’t change how you think about your drive to work.
“It’s like a choir, with all these supermassive black hole pairs chiming in at different frequencies,” Chiara Mingarelli, a NANOGrav scientist who worked on the new findings, said in a press release.
However, this is a HUGE deal. And those of us who follow these things are FREAKING OUT. Science is amazing. Life is amazing. This Creation that we get to participate in briefly is AMAZING!
Scientists Find the Gravitational Wave Background: What It Means:
Well, here it is. And it really is the big one!
Scientists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) have officially made the first detections of the gravitational wave background.
They made the first detections of what? Fair question, especially if you haven’t, in fact, been extremely tuned in to physics and astronomy Twitter. So let’s back up…
“What’s next is everything,” she said in a press release. “This is just the beginning.”
Corrected identification of object about to hit the moon:
Short version : back in 2015, I (mis)identified this object as 2015-007B, the second stage of the DSCOVR spacecraft. We now have good evidence that it is actually 2014-065B, the booster for the Chang’e 5-T1 lunar mission. (It will, however, still hit the moon within a few kilometers of the predicted spot on 2022 March 4 at 12:25 UTC, within a few seconds of the predicted time.)
Puts a different spin on that fishing trip after I’ve always told myself “it’s ok, fish don’t feel pain” (to paraphrase Kurt Cobain)…
I was the first to identify the existence of nociceptors in a fish, the rainbow trout, in 2002. These are specialised receptors for detecting injury-causing stimuli, and their physiology is strikingly similar to those found in mammals, including humans. Since then, my laboratory and others across the world have shown that the physiology, neurobiology, molecular biology and brain activity that many fish species show in response to painful stimuli is comparable to mammals.

The researchers explain the universe as a learning system by invoking machine learning systems. Just like we can teach machines to perform unfolding functions over time, that is, to learn, the laws of the universe are essentially algorithms that do work in the form of learning operations.

Evidence is mounting that a tiny subatomic particle called a muon is disobeying the laws of physics as we thought we knew them, scientists announced on Wednesday.
The best explanation, physicists say, is that the muon is being influenced by forms of matter and energy that are not yet known to science, but which may nevertheless affect the nature and evolution of the universe. The new work, they said, could eventually lead to a breakthrough in our understanding of the universe more dramatic than the heralded discovery in 2012 of the Higgs boson, a particle that imbues other particles with mass.

Perhaps they’re trying to tell us something, Like the dolphins who do a double-backward somersault through a hoop while whistling the Star Spangled Banner, the whales may be sending us a message that we’re misinterpreting as an adorably sophisticated trick. The oceans are warming, the seas are rising, and maybe—just maybe—the whales have had enough. They’ve gathered as many young humpbacks as possible to come together and send one final message: so long, and thanks for all the krill. Or maybe they’re talking to a giant space probe. Who knows.

Many mental ingredients are necessary for religion as-we-know-it. But scholars emphasize three tendencies in particular, which are pronounced in humans, but minimally expressed in other species:

Aliens exist, there’s no two ways about it. There are so many billions of stars out there in the universe that there must be all sorts of different forms of life. Will they be like you and me, made up of carbon and nitrogen? Maybe not. It’s possible they’re here right now and we simply can’t see them

Well this is an eye-opening piece that has caused me to reconsider lots of presuppositions…
In other words, to solve the problem of our unwillingness to keep track of our dogs, we do not address our own unwillingness. To address the overpopulation of unwanted dogs, we do not address the overpopulation. Instead, we non sequitur: we take brand-new dogs and introduce them into our homes by first putting them through a surgery at six, four, or even three months of age. The professed solution, in the United States, is to spay or neuter all the new ones.

In 1933 nuclear physicist Marie Curie had outgrown her lab in the Latin Quarter in central Paris. To give her the space needed for the messy task of extracting radioactive elements such as radium from truckloads of ore, the University of Paris built a research center in Arcueil, a village south of the city. Today it’s grown into a crowded working-class suburb. And the dilapidated lab, set in an overgrown garden near a 17th century aqueduct, is sometimes called Chernobyl on the Seine.

Climate change is the ghosts of impacts future….
And so the most effective guard against climate breakdown may not be technological solutions, but a more fundamental reimagining of what constitutes a good life on this particular planet. We may be critically constrained in our abilities to change and rework the technosphere, but we should be free to envisage alternative futures. So far our response to the challenge of climate change exposes a fundamental failure of our collective imagination.
In the end, that data was the “equivalent to 5000 years of mp3 files” according to Dan Marrone, an astronomer and co-investigator of Event Horizon Telescope. It was recorded onto half a ton of hard drives and then physically sent to centralized locations where it was analyzed by supercomputers for months in order to get the image we see today.

The reason why we experience reality as a movie when it’s only a collection of pictures can be at least partially explained by our rhythms of attention. About four times every second, the brain stops taking snapshots of individual points of focus — like your friend on the corner in Times Square — and collects background information about the environment. Without you knowing it, the brain absorbs the sound of the crowd, the feeling of the freezing December air — which it later uses to stitch together a narrative of the complete Times Square Experience.

I love this story (not just because I have an unhealthy obsession with bags and man purses)…
For whatever reason, Armstrong seemingly kept the bag a secret for more than four decades. Even when questioned about mementos by his authorized biographer, Armstrong made no mention of the historic artifacts that were tucked away in his closet.
To be clear, the bag was not something Armstrong snuck home from the moon. After returning to lunar orbit, the bag and its contents were moved from Eagle to the command module “Columbia” before the lander was directed to crash back to the surface. Had the purse remained aboard, it too would have been destroyed.

Hmm… being the parent of a current toddler, I’m going to take an initial pass on this upgrade offer.
Still, the results provide an interesting look into how the brain can store and ‘forget’ memories from childhood – and it’s tantalising to think that our very earliest moments in life might really be locked up in our neurons somewhere.

It’s safe to say that Hawking inspired so many people of my generation (and generations after us, hopefully) with his wit and humor along with his insights into the workings of black holes and the cosmos.
As a teenager who dove into the world of astronomy and cosmology as an escape from my small rural hometown, I always found Hawking as an incredible enigma with his dense articles, pop-sci books, and then appearances on The Simpsons and Star Trek: The Next Generation (all of which I cherished and continue to do so.
As a Middle School Science Teacher, I frequently used video clips of Prof. Hawking to make a point about space or black holes or the need for humble humor in all of our exploits.
Rest easy and continue to spur us forward in our journey to the stars, Prof. Hawking.
“His final resting place lies between the remains of two other famed scientists, Charles Darwin and Isaac Newton.
It is a rare honor to be interred at the Abbey, and one that has not been given to a scientist for almost 80 years. Before Hawking, the last scientists laid to rest at Westminster were atomic physicists Ernest Rutherford in 1937 and Joseph John Thomson in 1940.”

This is beautiful. Why didn’t I know this already?
Fingerprints are formed by friction from touching the walls of our mother’s womb. Sometimes they are called “chanced impressions.” By Week 19, about four months before we are issued into the world, they are set. Gorillas, chimpanzees, and koalas also possess exclusive prints.

It’s more the fetus touching the amniotic sac combined with genetics, but it’s still a striking thought. Here’s a helpful video I found on the topic.
When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human. “If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation…exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

20 qubits have been entangled together and put into one network. Huge… computing is about to get “spooky” as Einstein would have said.
In high school physics, electrons bounce between two layers, like a car changing lanes. But in reality, electrons don’t exist in one place or one layer — they exist in many at the same time, a phenomenon known as quantum superposition. This odd quantum behavior offers a chance for devising a new computer language — one that uses infinite possibilities. Whereas classic computing uses bits, these calcium ions in superposition become quantum bits, or qubits. While past work had created such qubits before, the trick to making a computer is to get these qubits to talk to one another.
