A city is a science experiment. What happens when we separate human beings from the environment in which they evolved? Can people be healthy without nature? The results have beenbleak. Countless studies have shown that people who spend less time in nature die younger and suffer higher rates of mental and physical ailments.
“There’s a really, really strong case for proximity to nature influencing health in a really big way,” said Jared Hanley, the co-founder and CEO of NatureQuant, an Oregon start-up whose mission is to discover what kind of nature best supports human health, map where it is and persuade people to spend more time in it.
Using satellite imagery and data on dozens of factors — including air and noise pollution, park space, open water and tree canopy — NatureQuant has distilled the elements of health-supporting nature into a single variable called NatureScore. Aggregated to the level of Census tracts — roughly the size of a neighborhood — the data provide a high-resolution image of where nature is abundant and where it is lacking across the United States.
When Your Vision and Hearing Decline with Age

Bons gráficos de linhas com ajuste de curvas
By Nathan Yau
If you want to feel like you’re getting old, visit an optometrist and have them tell you that in 6 to 12 months you won’t be able to read things up close and you’ll need bifocals.
For most of my life, I had good vision without glasses or contacts, but in my mid-30s I noticed the basketball score on television looking kind of blurry. I had astigmatism. Just a little.
My prescription didn’t change for years. Until recently. My optometrist hit me with the news that most people start to have trouble reading up close between 39 to 43 years old. I had to look into it.
The following chart shows the percentage of adults who wear glasses or contacts, by age, based on data from the National Health Interview Survey.

Airfoil

Excelentes animações sobre fenómenos físicos como o fluxo de ar em asas de avião ou noutros meios
The dream of soaring in the sky like a bird has captivated the human mind for ages. Although many failed, some eventually succeeded in achieving that goal. These days we take air transportation for granted, but the physics of flight can still be puzzling.
In this article we’ll investigate what makes airplanes fly by looking at the forces generated by the flow of air around the aircraft’s wings. More specifically, we’ll focus on the cross section of those wings to reveal the shape of an airfoil

The jobs of young people with higher incomes and what they studied
By Nathan Yau
Income tends to increase with age, because more work experience and education tends to lead to higher paying jobs. However, young people can also earn higher incomes. Using data from the most recent 2022 American Community Survey, let’s see what those people studied and what they do for a living.

More pets than children in Taiwan

boa estória com gráficos e animações excelentes
In 2018, Taiwan officially became an “aged society,” a label reserved for populations where 15-20% are 65 years or older. But that’s only the beginning. Taiwan’s on track to reach “super-aged society” status around 2025—that’s when the share of folks 65 or older goes over 20%. This rapid demographic shift makes Taiwan one of the fastest aging countries in the world, the social and economic implications of which will need careful planning and strategic policy to address.

Climate Disasters Drain US Emergency Fund, Adding to Government Shutdown Risk

bons gráficos de barras e de linhas acumulados e várias combinações deste tipo de gráficos
By Rachael Dottle and Leslie Kaufman Green + Politics
29 de setembro de 2023
Devastating fires in Maui and the fierce winds and rain of Hurricane Idalia are just two of the record 23 billion-dollar weather disasters the US has experienced so far this year, leaving little left in the primary government relief fund. Diminished resources combined with a potential shutdown of the federal government could hamper the response to any new disasters later this year.
Due in part to a warming climate, major disasters are increasing in frequency and cost, and federal spending on recovery has grown in step. The principal source of direct federal aid is the Disaster Relief Fund. This major source of individual and public aid managed by the Federal Emergency Management Agency is expected to be exhausted by the end of the fiscal year in September.

Why Momentum Really Works
Posted by Armando Brito Mendes | Filed under Data Science, infogramas \ dashboards, materiais ensino
Uma excelente explicação de como funciona o momentum em redes neuronais
Here’s a popular story about momentum [1, 2, 3]: gradient descent is a man walking down a hill. He follows the steepest path downwards; his progress is slow, but steady. Momentum is a heavy ball rolling down the same hill. The added inertia acts both as a smoother and an accelerator, dampening oscillations and causing us to barrel through narrow valleys, small humps and local minima.
This standard story isn’t wrong, but it fails to explain many important behaviors of momentum. In fact, momentum can be understood far more precisely if we study it on the right model.
One nice model is the convex quadratic. This model is rich enough to reproduce momentum’s local dynamics in real problems, and yet simple enough to be understood in closed form. This balance gives us powerful traction for understanding this algorithm.

How concrete, asphalt and urban heat islands add to the misery of heat waves
PUBLISHED JULY 31, 2023 15:40 AZOST
It only takes just a fraction of a second to suffer a pretty serious burn. Asphalt and concrete in direct sunlight can often reach surface temperatures as high as 82 Celsius (180 Fahrenheit) on the hottest days, said Dr. Kevin Foster, who directs the Arizona Burn Center in Phoenix.
Forecasters predict another heat wave in Phoenix this week after the U.S. National Weather Service declared the city had sweltered under high temperatures above 43°C (115°F) for 30 consecutive days in July. Across Europe, high temperature records have tumbled this summer and major heat waves in much of the world are expected to persist through August.
