The Untold Toll: How Many Birds Die Hitting Buildings?

2024-12-21

A recent study reveals a shocking truth: we drastically underestimate the number of birds killed by colliding with buildings. Previous research relied on finding carcasses, but many birds don't die instantly, succumbing days or weeks later. By combining carcass data with rehabilitation center records, researchers estimate over a billion birds die annually in the US from building collisions. This highlights the challenges of accurately assessing bird mortality and the need for improved data collection and analysis to better protect avian populations.

The Kelly Criterion: A Mathematical Approach to Insurance Decisions

2024-12-21

This article explores how the Kelly criterion can be used to make rational decisions about insurance.

Motorcycle and helicopter insurance examples illustrate the calculations and deductible's impact. The author explains how insurance companies profit and the relativity of costs.

California Ground Squirrels Caught Eating Meat: A Surprising Discovery

2024-12-21

A recent study has overturned long-held beliefs about California ground squirrels. Previously considered granivores (grain-eaters), researchers observed these common rodents hunting, killing, and consuming voles—small rodents—during the summer of 2024. This surprising discovery highlights the gaps in our understanding of even familiar animals and suggests California ground squirrels may be opportunistic omnivores, adapting their diet based on food availability. The observed carnivorous behavior, peaking when vole populations surged, demonstrates their behavioral flexibility and adaptability to changing environments.

Kelly Can't Fail: A Zero-Variance Gambling Game

2024-12-19

This article presents a card game called "Next Card Bet," where the Kelly betting strategy, typically known for its high variance, surprisingly exhibits zero variance. By counting the remaining red and black cards, the player calculates the optimal bet fraction to maximize the expected logarithm of their stake. Python simulations demonstrate consistent returns of approximately 9.08 times the initial stake across 10,000 runs, showing no variance. The article explains this zero-variance property by showing the Kelly strategy's equivalence to a portfolio strategy that distributes bets across all possible card arrangements. This portfolio strategy guarantees a specific return, independent of the card order, thus explaining the zero variance of the Kelly strategy in this unique game.

Polyamory Doesn't Liberate; Monogamy Doesn't Protect: A Bay Area Dating Retrospective

2024-12-19

This essay reflects on a decade of dating in the Bay Area, challenging the notion that polyamory is inherently liberating or monogamy inherently protective. Drawing on personal experiences and anecdotes from friends, the author argues that neither relationship style guarantees emotional fulfillment or prevents heartbreak. Statistical data on polyamory is analyzed, revealing complexities and contradictions. The author concludes that the key to successful relationships lies in self-awareness, communication, and addressing personal attachment issues, rather than solely relying on a specific relationship structure.

Artist Trains Rats to Predict Forex Markets

2024-12-19

Austrian conceptual artist Michael Marcovici's project, "Rat Traders," trained rats to predict foreign exchange futures prices. He converted price fluctuations into piano notes, and the rats predicted subsequent note changes. Surprisingly, trained rats seemingly outperformed human traders after months, though this lacked rigorous statistical testing. Marcovici's project satirizes the belief in market prediction and the human desire for shortcuts to profit in a chaotic system. The project ultimately ended due to rats' limited trading capacity, highlighting the unreliability of market prediction.

Santa Claus Shows Bias Towards Wealthy Sick Children: Study Sparks Debate

2024-12-19

A paper titled "Dispelling the nice or naughty myth" claims Santa Claus's gift-giving isn't solely based on children's behavior but strongly correlates with socioeconomic status. The study reveals that children in impoverished areas are less likely to receive gifts, raising ethical concerns and sparking debate. A cited Reddit comment suggests Santa's contract prevents altering socioeconomic status, limiting his ability to reach all children. The commentary section criticizes the methodology, sample selection, and even Santa's delivery timing and routes, suggesting Brexit voting data should be included. The paper's publication has caused a stir, with some even calling for its retraction.

America's Unexpected Health Boom: A Mystery Solved?

2024-12-19

Recent data reveals an unexpected improvement in American health, with decreases in drug overdose deaths, traffic fatalities, obesity rates, and murder rates. This contrasts sharply with America's long-standing image as a "rich death trap." While some attribute this to effective policies like increased access to drug addiction treatment and expanded availability of Narcan, experts suggest these policies' impact might be overstated. Other factors, such as the natural decline in overdose deaths post-pandemic and changes in law enforcement, likely played a role. The precise causes of this improvement remain unclear, highlighting the complexities of reality often obscured by simplistic explanations.

Kowloon Walled City: A Heterotopia in a Space of Disappearance

2024-12-19

Kowloon Walled City, a unique 'heterotopia' in Hong Kong, emerged from the political conflicts following the Opium Wars. Its ambiguous sovereignty made it a lawless zone, attracting refugees from China and fostering a vibrant, albeit illicit, economy.

Doomsday Predictions: Why People Always Feel the End is Nigh

2024-12-18

From Columbus's time onward, doomsday predictions have accompanied humanity. The author argues that people believe in them not for comfort, but because they seem logical. A 'Good Cup Bad Cup' theory is introduced: people pay more attention to bad things, and negative memories fade faster, leading to a perception that bad things are increasing and the world is deteriorating. Historical examples, from ancient Egyptian prophecies to the Millerite movement, support this: people always feel the present is worse than the past. The author calls for a rational perspective, urging readers to avoid biases and recognize positive changes.

A Glimpse into OS/2's Built-in Virtualization

2024-12-17

This blog post explores the surprisingly advanced built-in virtualization capabilities of OS/2 2.1 from 1993. The author demonstrates OS/2's ability to load and execute disk images, much like modern hypervisors, by creating a simple VGA mode program and running it in DOSBox, QEMU, and OS/2's own virtual environment. OS/2 can even run images that aren't true bootable DOS floppies, using VMDISK to create an image file and running it in fullscreen or windowed mode within OS/2. This functionality, remarkable for 1993, is essentially a built-in QEMU, prompting the author to consider the further potential of OS/2's virtualization features.
