Google Maps provides navigation services and real-time traffic information, and also allows users to search for restaurants and stores. Now a new function of Google Maps will enable users to view information on street level air quality, too.
At the beginning of this month, Google posted an air quality map on its official blog, showing air pollution levels for Oakland in California. On the map, pollution levels are color coded, with darker colors indicating higher air pollution levels.
The project to integrate Google Maps and air quality data has been jointly carried out by Google, the Environmental Defense Fund (EDF) and Aclima since 2015 in a number of cities. Google Street View cars were equipped with Aclima’s sensing devices to monitor the levels of nitric oxide (NO), nitrogen dioxide (NO2) and black carbon in the air.

For the moment, the project will focus on cities in the US. In addition to the city of Oakland, Google is also collecting air quality data in California’s Los Angeles and Central Valley, although it has not yet released air quality maps for any places other than these.(Taipei Times, translated by Tu Yu-an)
Google 地圖不只能導航、查詢交通路況、還可用來搜尋餐廳或商店，現在更新增顯示街道空氣品質的功能。
Google本月初在官方部落格公布一張空氣品質地圖，顯示美國加州奧克蘭市的空氣汙染情形。地圖上，可以看到不同的顏色，顏色越深，表示該地區的空氣汙染程度越高。

這項整合地圖和空氣品質資料的計畫，是由Google、美國環境保護局、環境檢測器廠商Aclima自二○一五年起針對特定城市所合作推出，主要利用設置在Google街景車上的環境感測器，測量空氣中的一氧化氮、二氧化氮、黑碳排放物。
這項計畫目前以美國地區為主。除了奧克蘭市，Google也正在著手於加州洛杉磯和中央谷地蒐集空氣品質資料，但尚未公布其他地區的空氣品質地圖。(台北時報記者涂宇安)
Long before numerals and arithmetic systems developed, humans relied on tally marks to count. These simple, repeated marks — often just straight lines — are one of the earliest and most widespread methods of recording numbers. Archaeological findings suggest that humans began tallying in prehistoric times. During the Late Stone Age in Africa, humans began to carve notches onto bones to create tangible records of quantities. One of the earliest known examples is the Wolf bone, an artifact unearthed in Central Europe in 1937. This bone bears notches believed to be an early form of counting. Even more intriguing
A: In addition to Teng Kai-wei, Taiwanese infielder Cheng Tsung-che was called up temporarily to play for the Pittsburgh Pirates in early April. B: Yeah, Cheng is the 18th player in Taiwan’s baseball history to be moved up to the majors. A: Back in 2002, Chen Chin-feng became the first Taiwanese to play in the Major League Baseball (MLB), followed by Tsao Chin-hui, Wang Chien-ming, Kuo Hung-chih, Hu Chin-lung and Lin Che-hsuan. B: Those pioneers were later joined by Lo Chia-jen, C.C. Lee, Ni Fu-te, Chen Wei-yin, Wang Wei-chung, Hu Chih-wei, Tseng Jen-ho, Lin Tzu-wei, Huang Wei-chieh, Yu Chang,
When Nvidia CEO Jensen Huang revealed on Friday last week that the company is working with the Trump administration on a new computer chip designed for sale to China, it marked the latest chapter in a long-running debate over how the US should compete with China’s technological ambitions. The reasoning has sometimes changed — with US officials citing national security, human rights or purely economic competition — but the tool has been the same: export controls, or the threat of them. Nvidia believes it can eventually reap US$50 billion from artificial intelligence (AI) chip sales in China. But it so far has
Continued from yesterday（延續自昨日） https://www.taipeitimes.com/News/lang In many Western countries, the most common form of tally marks employs a five-bar gate structure: four vertical lines followed by a diagonal slash. To form this group, one begins by drawing four parallel vertical lines, each representing one. For the fifth, draw a diagonal line across the existing four. This diagonal stroke effectively creates a distinct group of five. To continue counting, just initiate a new cycle in the same manner. A set of five tallies combined with a single vertical line next to it represents the number six. Across many Asian countries, the Chinese character
