Accurate Genomic Prediction Of Human Height | bioRxiv
Stephen Hsu's compressed sensing application paper

We construct genomic predictors for heritable and extremely complex human quantitative traits (height, heel bone density, and educational attainment) using modern methods in high dimensional statistics (i.e., machine learning). Replication tests show that these predictors capture, respectively, ~40, 20, and 9 percent of total variance for the three traits. For example, predicted heights correlate ~0.65 with actual height; actual heights of most individuals in validation samples are within a few cm of the prediction.

Global determinants of navigation ability | bioRxiv
Using a mobile-based virtual reality navigation task, we measured spatial navigation ability in more than 2.5 million people globally. Using a clustering approach, we find that navigation ability is not smoothly distributed globally but clustered into five distinct yet geographically related groups of countries. Furthermore, the economic wealth of a nation (Gross Domestic Product per capita) was predictive of the average navigation ability of its inhabitants and gender inequality (Gender Gap Index) was predictive of the size of performance difference between males and females.

- Figure 1 has the meat
- gender gap larger in richer/better-performing countries
- Anglo and Nordic countries do best (Finnish supremacy wins the day again)
- surprised China doesn't do better, probably a matter of development
- Singapore is close behind the Anglo-Nords tho
- speculation that practice of orienteering (originally Swedish) may be related to Nords doing well
- somewhat weird pattern wrt age

Reynolds number - Wikipedia
The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities, in what is known as a boundary layer in the case of a bounding surface such as the interior of a pipe. A similar effect is created by the introduction of a stream of higher velocity fluid, such as the hot gases from a flame in air. This relative movement generates fluid friction, which is a factor in developing turbulent flow. Counteracting this effect is the viscosity of the fluid, which as it increases, progressively inhibits turbulence, as more kinetic energy is absorbed by a more viscous fluid. The Reynolds number quantifies the relative importance of these two types of forces for given flow conditions, and is a guide to when turbulent flow will occur in a particular situation.[6]

Re = ρuL/μ

(inertial forces)/(viscous forces)
= (mass)(acceleration) / (dynamic viscosity)(velocity/distance)(area)
= (ρL^3)(v/t) / μ(v/L)L^2
= Re

NB: viscous force/area ~ μ du/dy is definition of viscosity

Will the global housing boom end in disaster? - CapX
UK house prices have recovered from the slump that followed the financial crisis. According to the Office of National Statistics UK house prices have risen 45 per cent since their trough in March 2009.

Over the same period earnings have risen by just 16 per cent making life tougher for first-time buyers and those trading up in the housing market.

National Greatness | West Hunter
As production rose, availability increased. At first, penicillin was largely reserved for US and British military needs. Later, it became available to US and British civilians, and soon after for general usage.

But there was a time window of several months in which American-produced penicillin was available for American wounded but not for French casualties. Fortunately, it happens that penicillin is rapidly excreted in urine. It can be recovered. Between January and April 1945, Rhône-Poulenc extracted penicillin from the urine of wounded American servicemen being treated in hospitals around Paris, penicillin which was then used to treat the wounded of the French Army. They typically recovered about 100 doses from 300 liters of urine.

When American piss is the elixir of life – that is national greatness.
