Nobel Prize Winners: A Data-Driven Look at Scientific Concentration and Dispersion

2025-03-26

This analysis examines data on Nobel Prize winners in Physics, Chemistry, and Medicine from 1915 to 2016, revealing a concentration of scientific achievements. A small number of countries, primarily the US, UK, and Germany, and elite universities like Harvard and Cambridge, dominate Nobel Prize wins. However, a long tail effect is also observed, with many other countries and institutions contributing. Furthermore, the average age of laureates and the time lag between completing prize-winning work and receiving the award are increasing, potentially indicating a slowdown in groundbreaking discoveries or inherent delays in the Nobel Prize selection process.

The Rise of Solar PV: A Cheap Energy Future?

2025-03-20

This article explores the rapid growth of solar photovoltaic (PV) power generation and its future potential. While currently accounting for only around 4% of total US electricity generation, the cost of solar PV has fallen nearly ten thousandfold in the last 70 years and is projected to fall further. However, the intermittency of solar power is a major challenge, as it cannot generate electricity on demand. The article uses simulations to explore strategies for addressing intermittency by increasing solar panel capacity and energy storage systems. It concludes that as solar and storage costs continue to decline, "overbuilding" to meet a larger fraction of electricity demand will become economically feasible. Ultimately, solar's low and declining costs make it a competitive energy option, but its intermittency remains a challenge to overcome.

Why Did Skyscrapers Become Glass Boxes? Economics, Not Modernism

2025-01-13

This article explores the shift in US skyscraper design from ornate brick and stone structures to the ubiquitous glass box. Contrary to the popular narrative of a modernist architectural conspiracy, the author argues that the driving force was economic efficiency. Glass curtain walls proved cheaper to construct, faster to erect, and offered greater rentable square footage. While tenants prioritize interior space, developers found that exterior ornamentation had little impact on rental prices, making cost-cutting a primary concern. Though some architects and developers still champion more expressive designs, the relentless pressure for profit maximization has solidified the glass box as the dominant aesthetic.

The Evolution of Tunnel Boring Machines: From Manual Labor to Automated Factories

2025-01-05

This article chronicles the century-long evolution of Tunnel Boring Machines (TBMs). Starting with Brunel's manual shield in 1825, through Greathead's improvements, Price's mechanized excavation, and culminating in modern slurry and earth pressure balance TBMs, the article details breakthroughs in both soft ground and hard rock tunneling. The article also explores compressed air and slurry support technologies, the advantages and disadvantages of different TBM types, and analyzes Elon Musk's Boring Company and its ambitious—yet currently slow—progress. The Boring Company's vertically integrated structure may ultimately revolutionize the industry.

Apollo Program: The Untold Story of Engineering Triumph and Tragedy

2025-01-02

This article reviews Mike Gray's book, *Angle of Attack: Harrison Storms and the Race to the Moon*, focusing on North American Aviation's pivotal role and chief engineer Harrison Storms's struggles in the Apollo program. From blueprints to launchpad, Storms led his team through countless challenges, including developing the supersonic B-70 bomber and the X-15 hypersonic aircraft, and advancing rocket engine technology. Apollo's success relied heavily on Storms' team's innovations in materials science, welding, and rocket construction. However, after the Apollo 1 fire, Storms was unjustly dismissed, fading into relative obscurity. This book reveals the human cost and unforeseen challenges behind one of humanity's greatest achievements.
