每日英語跟讀 Ep.789: About Science - ’Earth sandwich’ made by two men 20,000km apart
Sierra and Naude have created an "Earth sandwich" - by placing bread on precise points, either side of the planet, at the same time.
Naude from New Zealand wanted to make one for years, but had struggled to find someone in Spain, on the other side of the globe.
Two months ago, he posted on the Spain section of the online message board Reddit. He got "a few replies" and found one person close to the precise location.
The men used longitude and latitude to make sure they were precisely opposite.
According to World Atlas, only around 15% of "territorial land" is antipodal to other land. Naude only had to travel a few hundred metres to find a suitable public spot on his side of the world. Mr Sierra had to travel 11 km .
Human ’screenome’ may give insight into human health 人類「螢幕特質」可探究人類健康
To understand how people use digital media, researchers need to move beyond screen time and capture everything we do and see on our screens.
Digital media — in particular, social media — have powerful and invariable effects on human behaviour. Policies and advice must be informed by accurate assessments of media use. These should involve moment-by-moment capture of what people are doing and when, and machine analysis of the content on their screens and the order in which it appears.
According to a 2019 systematic review and meta-analysis, over the past 12 years, 226 studies have examined how media use is related to psychological well-being.
The meta-analysis found almost no systematic relationship between people’s levels of exposure to digital media and their well-being. But almost all of these 226 studies used responses to interviews or questionnaires about how long people had spent on social media.
