How bike-sharing conquered the world

“Health benefits are harder to quantify, especially in smoggy cities like Beijing. Mobike has found that its bikes are used more or less as much when the air is really bad as when it is not, suggesting that the good done by exercise may be undone by heavy breathing in toxic air. But in less-polluted cities the gains from exercise are larger than the risks from road accidents or air pollution, according to a study of Barcelona in the British Medical Journal.

On Your Bike, Watch Out for the Air – The New York Times

September 2, 2017

QT:{{"
“This elaborate gadgetry is part of a five-year study that aims to find out at what point the harm done by pollution to cyclists might outweigh the health benefits accrued from the exercise.

The strapped-on sensors measure levels of PM 2.5, the fine particulate matter that is about one-thirtieth the diameter of a human hair and thought to be particularly harmful to health. The tiny particles, including black carbon, the main component of soot, penetrate deep into the lungs and bloodstream and may lead to the development of respiratory illnesses like asthma and lung cancer. Even relatively short-term exposures can increase body-wide inflammation and boost the likelihood of strokes and heart attacks.

A 2014 report issued by the New York City Health Department said that particulates in the air cause more than 2,000 premature deaths and 6,000 emergency room visits and hospitalizations each year.

We still don’t really know how bicycles work

We still don’t really know how #bicycles work
http://www.NewStatesman.com/science/2013/08/we-still-don%E2%80%99t-really-know-how-bicycles-work Still rides upright with special wheels cancelling gyroscopic effect

QT:{{”
“The most definitive analysis came exactly a century later. It involved an experimental bicycle that had all its gyroscopic effects cancelled out by a system of counter-rotating wheels. The effort of building such a strange contraption was worth it: the resulting paper was published the prestigious journal Science.
The publication plunged bicycle dynamics back into chaos. It turns out that taking into account the angles of the headset and the forks, the distribution of weight and the handlebar turn, the gyroscopic effects are not enough to keep a bike upright after all. What does? We simply don’t know. Forget mysterious dark matter and the inexplicable accelerating expansion of the universe; the bicycle represents a far more embarrassing hole in the accomplishments of physics.”
