Episode 438: The Real Book - Summary

Since the 1970s, nearly every jazz musician has owned a book called the Real Book, which has a peach cover and contains hand-written sheet music for many jazz standards. However, this book was initially illegal, as it was self-published without permission from music publishers or songwriters and was sold covertly.

The origin of the Real Book is linked to earlier "fake books," which emerged in the 1940s to help musicians play popular songs without carrying large amounts of sheet music. These fake books faced backlash from publishers who wanted to sell legal sheet music.

The Real Book was created in the mid-70s by two students at Berklee College of Music who wanted a modern collection that included contemporary jazz tunes and updated chord changes. They produced copies to sell to fellow students, but soon bootleg versions appeared worldwide, leading to a surge in demand.

In the mid-2000s, Hal Leonard published a legal version of the Real Book, ensuring composers received royalties, but some intellectual property issues remained unresolved, particularly regarding authorship of jazz songs.

While the Real Book is a useful tool for learning jazz, critics argue it oversimplifies the genre. Musicians like Nicholas Payton emphasize that jazz is more than just notes on a page; it's about cultural immersion and personal expression. Others, like Carolyn Wilkins, see the Real Book as a helpful starting point but stress the importance of exploring diverse interpretations of jazz music.

A recent study has found that certain tropical trees, specifically the Dipteryx oleifera, can not only survive lightning strikes but may actually benefit from them. Led by forest ecologist Evan Gora, the research showed that these trees can act like lightning rods, experiencing minimal damage while helping to eliminate competition from nearby plants.

The study tracked 93 trees struck by lightning in Panama and discovered that while D. oleifera trees survived with minor damage, other species suffered significant loss, with many dying shortly after being struck. The strikes reduced the number of parasitic vines on D. oleifera trees, allowing them to grow better and compete for resources more effectively.

The researchers suggest that D. oleifera trees may have evolved to attract lightning due to their height and wide crowns. On average, these trees are struck by lightning every 56 years and can live for hundreds of years, benefiting from multiple strikes throughout their lifespan.

The findings highlight the important role that lightning plays in forest dynamics and could influence biodiversity and carbon storage, especially as climate change increases lightning frequency. Future research will explore what traits allow these trees to survive lightning and whether other species have similar adaptations.

His journey revealed that while some agencies denied his requests, many complied and provided data about his vehicle. He noted the locations and times where his car was captured on camera, emphasizing how surveillance can reveal patterns of behavior.

The author reflected on the implications of such technology, indicating it could be used to track individuals without their knowledge. He expressed concerns about privacy, as public surveillance data can be accessed by police without a warrant, raising questions about oversight and individual rights. Ultimately, the investigation highlighted a shift in expectations of privacy in public spaces, suggesting that people may no longer have the right to view how they are monitored by the government.

Scientists at RIKEN in Japan have created a new type of plastic that dissolves in saltwater overnight without leaving harmful microplastics. This biodegradable plastic is made from supramolecular polymers, which have reversible bonds that allow them to be strong during use but break down easily when submerged in saltwater.

The new plastic is created by mixing sodium hexametaphosphate, a common food additive, with guanidinium ion-based monomers found in fertilizers. This combination forms a flexible and strong material that dissolves in about eight and a half hours in saltwater, breaking down into safe compounds like nitrogen and phosphorus, which can benefit plants and microbes.

To prevent the plastic from dissolving prematurely, researchers have developed hydrophobic coatings. This means the plastic can be used safely without breaking down until it is intentionally scratched to allow saltwater in for disposal.

Overall, this new biodegradable plastic is a promising alternative to traditional plastics, as it poses less risk to the environment and can potentially be beneficial if it ends up in the ocean.

Summary:

Researchers have found that phasons, which are quasiparticles in crystal lattices, allow interlayer excitons to move even at very low temperatures, where movement usually stops. This discovery enhances our understanding of materials science and may improve the stability of quantum technologies, such as qubits.

The study, conducted at the Molecular Foundry, involved stacking thin semiconductor layers called transition metal dichalcogenides (TMDs). When these layers are stacked, they create a moving moiré potential, which was previously thought to be stationary. This potential plays a key role in the movement of excitons, which are pairs of electrons and holes created when light interacts with these materials.

The researchers observed that excitons could move within the moiré potential, which behaves like a dynamic seascape. They discovered that the excitons’ mobility is influenced by temperature and the alignment of the layers. Surprisingly, even close to absolute zero, the excitons still exhibit some movement instead of completely freezing.

This research opens new avenues for exploring other semiconductor systems and understanding the role of phasons in materials. The findings contribute to the broader goal of advancing quantum information systems.

Summary: Are Levi’s From Amazon Different From Levi’s From Levi’s?

In a recent exploration during "Jeans Month," the Strategist investigated whether Levi's jeans purchased from Amazon are of lower quality than those bought directly from Levi's. After receiving a tip about quality differences, the author tested pairs of popular Levi's styles from both retailers.

Key findings included:

• The jeans from Amazon and Levi's had noticeable aesthetic differences, such as variations in color and texture, but these did not indicate a significant difference in quality.
• Testing at a lab showed that while the denim from both sources varied, most pairs performed similarly in terms of strength and durability.
• Levi's sources fabric from various global mills, which can lead to differences in production quality and appearance.

Ultimately, the assessment indicated that while there might be some differences between Levi's jeans from different retailers, the quality of jeans from Amazon is not necessarily worse than those from Levi's own store.

Researchers have discovered that an ancient organism called Prototaxites, which was once thought to be a type of giant fungus, may actually belong to an entirely unknown branch of life. Prototaxites existed around 420 to 375 million years ago and resembled large, branchless tree trunks, reaching heights of up to 26 feet (8 meters). Initially classified as a fungus based on chemical analysis, recent studies suggest it might not fit into any known categories of life, including fungi, plants, or animals.

A recent study focused on a smaller species of Prototaxites called Prototaxites taiti, found in Scotland. Researchers found that its internal structure was unlike any known fungi and lacked chitin, a key component of fungal cell walls. Instead, it showed similarities to lignin, which is found in plants. This leads scientists to propose that Prototaxites is part of a previously unknown group of eukaryotes.

Further research is needed to fully understand Prototaxites and what caused its extinction. The findings have sparked interest and curiosity in the scientific community, hinting at the possibility of undiscovered life forms in Earth's history.

In robotics and VR/AR, fast camera movements often lead to motion blur, which can disrupt camera pose estimation methods. This work introduces a new framework that uses motion blur as a helpful tool for estimating motion instead of seeing it as a problem. The method predicts a detailed motion flow and depth map from a single blurred image, allowing us to calculate the camera's speed. We create a large dataset of realistic motion blur for training and improve our model with real data. Tests show our approach provides the best estimates for camera movement compared to existing methods like MASt3R and COLMAP.

Summary of "The Unbearable Loudness of Chewing" by Jake Eaton

Many people experience intense discomfort from certain sounds, particularly chewing, a condition known as misophonia. The author shares his personal struggle with this condition, which began in adolescence when he became unable to tolerate the sounds of his father's chewing. Misophonia can lead to feelings of anger and disgust, disrupting daily life and relationships.

Despite its recognition for over 20 years, scientific understanding of misophonia remains limited. Researchers have debated its origins—whether it's a neurological, psychiatric, or sensory disorder. The term was first used in a 2001 study, but it gained more attention in recent years, particularly after a 2013 article identified it as a new psychiatric disorder.

Research on misophonia has increased since 2019 due to new funding, leading to better-defined questionnaires and increased awareness. A 2024 study found that while many people report sensitivity to triggering sounds, only a small percentage meet the criteria for clinical misophonia.

There is still no consensus on whether misophonia can be classified as a medical disorder. Current treatments, like cognitive-behavioral therapy (CBT), show promise but are not definitive. The author reflects on his own experience with misophonia and acknowledges the need for further research and understanding, emphasizing that living with this condition may require ongoing work and coping strategies rather than a simple cure.

Summary of "Introducing clean, a formal verification DSL for zk circuits in Lean4"

Giorgio Dell'Immagine introduces "clean," a new domain-specific language (DSL) for formal verification of Zero Knowledge (ZK) circuits using Lean4. ZK circuits often have bugs, but formal verification techniques can enhance their reliability. Clean allows users to define circuits, specify their properties, and prove their correctness, contributing to the zkEVM Formal Verification Project.

Objectives:

• Build a DSL for writing ZK circuits in Lean4.
• Create a library of reusable, formally verified circuit components.
• Support AIR arithmetization and include a lookup primitive.

Formal Verification Process:

1. Define the circuit's supported operations.
2. Set the semantics for these operations.
3. Specify properties to prove for each circuit.

Circuits consist of variables and constraints. The goal is to ensure that if the constraints are satisfied, the specified properties hold true, and vice versa.

Key Properties:

• Soundness: If a witness satisfies the constraints, then a specification property holds.
• Completeness: For every input, an honest prover can exhibit a witness that satisfies the constraints.

DSL Features: The DSL supports operations like introducing new variables, adding constraints, defining lookup relations, and composing subcircuits. It offers a user-friendly monadic interface for circuit definitions.

FormalCircuit Structure: This structure encapsulates the circuit definition, assumptions, specifications, and proofs of soundness and completeness, allowing for the reuse of verified components.

Example: 8-bit Addition Circuit: The article walks through implementing and verifying an 8-bit addition circuit, detailing input/output definitions, assumptions, specifications, and the proof structure.

Future Work: The project is in early development stages, with plans to:

Summary: Golang on the PlayStation 2

The author, Ricardo, is exploring the possibility of running Go programming language code on the PlayStation 2 (PS2), a console released by Sony in 2000. He finds this intriguing because traditional development for consoles typically uses lower-level languages. Ricardo aims to use TinyGo, a Go compiler for small devices, to overcome the limitations of Go's support for the PS2's architecture.

Key challenges include:

1. Lack of Direct Support: Go doesn’t natively support the PS2's Emotion Engine CPU, which requires a workaround using TinyGo.
2. Technical Complexity: The PS2 uses the MIPS R5900 architecture, and integrating with the existing ps2dev SDK introduces compatibility issues.
3. Emulator Testing: Ricardo conducts his experiments in an emulator rather than on actual hardware for convenience.

He details the process of configuring TinyGo to target the PS2, addressing issues with generating compatible binaries and linking to ps2dev libraries. He also explains the creation of custom runtime definitions and functions necessary for Go to operate on the PS2.

Further complications arise from the PS2's architecture, specifically the absence of certain MIPS instructions like DDIVU, which affects how integer divisions are handled. Ricardo devises a solution by modifying TinyGo to use auxiliary functions for division.

Looking ahead, he plans to implement more features and optimizations, such as handling floating-point operations and syscalls. He encourages others to experiment with the setup and promises more updates on his progress.

Scientists at RIKEN in Japan have developed a new type of plastic that dissolves in saltwater, potentially helping to reduce the microplastics pollution crisis. Microplastics are tiny plastic particles that harm the environment and human health. The new material, known as supramolecular plastic, is similar in strength and weight to regular plastics but can biodegrade quickly in seawater, preventing microplastic formation.

This innovative plastic is made using a combination of sodium hexametaphosphate and guanidinium ion-based monomers, which create strong bonds that can break down in saltwater. The plastic can self-heal and be easily recycled. After testing, the team found that it disintegrated in saltwater within 8.5 hours.

While the biodegradable material leaves behind nutrients that can enrich soil, careful management is needed to avoid overloading ecosystems. Researchers emphasize the need for a shift in the plastics industry to address plastic pollution effectively before production and carbon emissions increase significantly by 2050.

Artificial intelligence (AI) is increasingly being used in healthcare to improve patient care, such as detecting heart issues and diagnosing autism. However, a recent study shows that AI models can exhibit bias, particularly against marginalized groups like women and Black individuals. The study tested an AI model called CheXzero, designed to analyze chest x-rays, and found it often failed to accurately detect diseases in these groups, especially in Black women and younger patients.

Researchers discovered that CheXzero could predict patient characteristics like race and sex from x-rays with high accuracy, suggesting it might use these traits as shortcuts, leading to biases in diagnosis. When the model was provided with this demographic information, its detection rates improved, but only for some conditions.

The study highlights the need for more diverse training data to reduce bias in AI models. Experts argue that while AI can assist in healthcare, human oversight remains crucial to ensure fair and accurate patient care.

This text discusses "Piranesi's perspective trick," a unique artistic technique used by the 18th-century artist Giovanni Battista Piranesi. Piranesi is known for his detailed etchings of buildings in Rome, which often appear more legible and identifiable than real photographs. Key points include:

1. Piranesi's Style: His engravings provide a sense of place and often feature wide panoramic views without the distortions common in photographs.

2. Perspective Trick: Piranesi used a method where similar objects appearing in the distance are drawn as larger versions of those closer to the viewer, which is not how true perspective works. This technique allows for more elements in a scene while maintaining clarity.

3. Comparison to Modern Techniques: The text explains how modern software, like Hugin, developed a "Panini projection" to replicate wide-angle views without distortions. However, this is not the same as Piranesi's method.

4. Legibility: Piranesi’s approach makes images easier to read compared to traditional perspectives, which can appear distorted.

5. Applications: The technique can be applied in modern image editing, offering a new way to represent scenes more legibly than standard perspective methods.

Overall, Piranesi’s perspective trick remains relevant and can be seen in various historical and modern artworks.

Summary of E360 Digest - March 24, 2025

Research published in Nature Climate Change reveals that since 2000, melting Arctic glaciers have uncovered about 1,500 miles of coastline, mainly in Greenland. This retreat of glaciers has exposed valuable resources, but it also poses risks, as the newly uncovered land is prone to erosion and landslides. For instance, in September 2023, a glacier in eastern Greenland collapsed, causing a large landslide that generated a significant tsunami.

This week, scientists announced the discovery of long-chain alkane molecules in Martian rock samples collected by the Curiosity rover in 2013. These larger molecules were not found in earlier analyses due to the different treatment of the samples this time, which involved heating them strongly before analysis. The specific compounds detected are decane, undecane, and dodecane, but they were found in small amounts.

The analysis used a technique involving heating samples up to 850°C, which helps to release organic materials for detection. However, a previous issue with a reagent leaking into the instrument complicated the analysis, leading to a need for adjustments in the procedure to minimize contamination.

The long-chain alkanes detected are thought to be products of decarboxylation from fatty acids, which could hint at the presence of these acids on Mars. While fatty acids on Earth typically come from living organisms, they can also be formed through non-biological processes. It's uncertain whether the detected molecules are biotic or abiotic, and further analysis of returned samples from Mars is needed to clarify their origins.

NASA's Perseverance rover is currently storing samples for a planned return to Earth, but the mission's complexity and costs have made timelines uncertain. The search for evidence of life on Mars continues, with the possibility that any Martian life forms may be single-celled and difficult to detect.

Cloudflare has introduced a new feature called AI Labyrinth, designed to confuse and slow down unauthorized bots that ignore "no crawl" directives.

Key points include:

1. Purpose: AI Labyrinth aims to distract unwanted bots while collecting data on their behavior to improve bot detection systems.

2. How It Works: When suspicious bot activity is detected, AI Labyrinth generates convincing but irrelevant pages that bots might crawl, making it harder for them to gather useful information.

3. Implementation: Users can easily enable this feature in their Cloudflare dashboard with a simple toggle.

4. Benefits: The approach not only confuses bots but also helps identify them as they navigate through the maze of AI-generated pages, contributing to better bot detection.

5. Future Plans: Cloudflare plans to enhance this feature by making the AI-generated links more integrated with existing website structures and harder for bots to detect.

Overall, AI Labyrinth is a proactive tool for protecting websites from unwanted bot activity while maintaining a seamless experience for legitimate users.

In a recent Q&A session at NVIDIA's GTC event, CEO Jensen Huang expressed frustration that his vision for the company and its future wasn't being understood by analysts and the public. He emphasized that NVIDIA is not just a GPU company but an infrastructure company focused on building AI systems, which he referred to as "AI factories." Despite his repeated questions to the audience about their understanding, it became clear he felt his message was not resonating.

The author argues that the issue lies not with the audience's comprehension but with NVIDIA's failure to connect with them. Many people, especially outside the tech industry, are unfamiliar with NVIDIA and its products. Unlike well-known consumer brands like Apple or Amazon, NVIDIA's advancements in AI technology do not directly impact the daily lives of most individuals.

To bridge this gap, NVIDIA should simplify its messaging, making it relatable and understandable to the general public. By focusing on real-world applications of AI that address everyday problems, such as improving government services or enhancing shopping experiences, NVIDIA can better demonstrate its relevance. The author suggests that NVIDIA needs clearer naming and framing of its products to make them more accessible and memorable to consumers. Ultimately, to gain broader acceptance, NVIDIA must connect its innovations with the tangible benefits they can offer to everyday people.

Scientists have successfully created and characterized "berkelocene," the first organometallic molecule containing the heavy element berkelium (atomic number 97). This discovery challenges old theories about how elements after uranium behave chemically.

The research team from the Lawrence Berkeley National Laboratory used a tiny amount (0.3 milligram) of berkelium-249, which is highly radioactive and sensitive to air and moisture. They developed special equipment to safely study this compound.

Berkelocene consists of a berkelium atom between two carbon rings, and it exhibits a unique chemical bond with carbon, suggesting that berkelium behaves differently than previously thought, particularly with a stable positive charge of +4.

This finding could help improve models for understanding the chemistry of actinides, which is important for nuclear waste management. The team's work was supported by the U.S. Department of Energy.

Summary: The Role of Woodpeckers in Forest Ecosystems

Woodpecker nest holes are crucial habitats that benefit numerous species in forests. Researchers are studying "nest webs" to track how these valuable resources are shared among different animals.

Many birds, up to 20% of species globally, use tree cavities for nesting and roosting, with woodpeckers being the primary excavators of these holes. In North America, species like the Northern Flicker create cavities that serve as homes for various birds, mammals, and insects. These holes provide safe, dry, and easily defendable spaces for raising young and hiding from predators.

Kathy Martin's research in British Columbia highlighted that about 30% of North American forest birds utilize tree cavities at some point in their lives. Woodpeckers are essential as they create and maintain these habitats. For example, Northern Flickers excavate almost half of the cavities used by other species, while Red-cockaded Woodpeckers are unique in their ability to drill into live trees, providing vital nesting sites in longleaf pine forests.

The research also indicates that woodpeckers help facilitate the growth of certain fungi, which may enhance the health of trees and their ecosystems. In the face of climate change and forest fires, woodpeckers play a critical role in forest recovery by creating new nesting sites and helping other species adapt to changing conditions.

In summary, woodpeckers are essential for maintaining the health and diversity of forest ecosystems, benefiting many other species through their nesting cavities. Their conservation is vital for the overall health of forest habitats.

Summary: Adding a New Backend to Futhark

Scott Pakin suggested creating a blog post about adding new backends to the Futhark compiler. This post outlines the general process without going into detailed technical specifics. The complexity of adding a backend can vary significantly, from simple commands to complex new hardware implementations.

The Futhark compiler has three main parts:

1. Frontend: Parses and type-checks the Futhark source code, converting it into an intermediate representation (IR).
2. Middle-end: Refines and optimizes the program through various IR dialects.
3. Backend: Converts the IR into a lower-level representation (like C).

The compiler supports multiple targets (CPUs, GPUs, etc.) and uses parameterized representations to avoid code duplication. Each backend is defined as an “action,” which is a procedure that works on the IR produced by the middle-end.

To write a new backend, you need to select an appropriate pipeline for transforming the IR and then define the backend action. While adding a backend is not overly complex, understanding the existing infrastructure and documentation is vital. Advice for potential developers includes:

• Use Futhark's frontend and middle-end for high-level languages.
• For lower-level code, utilize IR dialects with memory information.
• Contact Futhark developers for guidance, as past backends were created with their close supervision.

Overall, adding a backend offers challenges but is a feasible task, and the developers welcome new contributions.
