This year, 2020, marks the 50th anniversary of Earth Day, a time to turn our attention toward the environment and raise awareness about threats to its well-being, from air pollution to climate change. But why does Earth Day fall on April 22? Is there any to the date?

When the inaugural Earth Day was first by Wisconsin Senator Gaylord Nelson and San Francisco activist John McConnell in 1970, a date was needed that would allow for activists attending college to be free to participate, a point made by organizer Denis Hayes. April 22 fell between spring break and final exams for most universities.

While that was a matter of logistics, April 22 also has a deeper meaning. Earth Day was inspired in part by Arbor Day, a tree-planting event that was organized by Nebraska native Julius Sterling Morton in 1872. Arbor Day was set for April 10. Later, when Arbor Day was declared a legal holiday by Nebraska, the state honored Morton by changing the date to his birthday—April 22.

美女视频黄频大全视频McConnell actually preferred the Spring Equinox for Earth Day, since marking the changing of the seasons and a balanced amount of daylight and darkness represented Earth’s unique traits. Because April 22 allowed college students to be more active in the events, however, that was the date that stuck.

美女视频黄频大全视频The modern Earth Day, with its themed objectives and upbeat spirit, is a marked departure from the first Earth Day in 1970, which had demonstrations that bordered on protests. (One enthusiastic group smashed an old Chevrolet to condemn air pollution.) The 2020 edition has a new theme—Climate Action—and will be celebrated virtually. While the world recognizes Earth Day, outside the U.S. it’s actually known by another name: International Mother Earth Day.

The Real Reason Why Wendy's Burgers Are Square

Wendy's signature square hamburgers have become as closely associated with the brand as its red-headed mascot. The burger chain isn't shy about the quality of its beef, making it the center of numerous ad campaigns美女视频黄频大全视频. But what does a patty's shape have to do with how it tastes?

美女视频黄频大全视频According to , the choice to make the burger's square is more of a clever marketing maneuver than a culinary choice. When Dave Thomas opened the first Wendy's restaurant in 1969, he wanted guests to see the quality of the meat. By shaping the burgers so that their edges peeked past the bun, he was showing he didn't in a very literal way.

Over the decades, this commitment to an unconventional burger shape would backfire. Some customers have accused the square beef patties of looking unnatural and processed, which is the exact opposite of what they're supposed to convey. The fast food company responded to these criticisms in by rounding the edges of their burgers slightly to give them a more "natural" square appearance.

Though theirs may be the most iconic example, Wendy's didn't invent the square patty. White Castle's angular burgers predate Wendy's by decades. The chain's founder claimed to have borrowed the look from Kewpee’s, a restaurant in his hometown of Kalamazoo, Michigan. Here are more facts about Wendy's you should know.

Why Do Virtual Assistants Like Siri and Alexa Traditionally Have Female Voices?

With the notable exception of HAL 9000 in Stanley Kubrick’s seminal 2001: A Space Odyssey (1968), most of the voices we associate with faceless artificial intelligence are female. Products like Amazon’s Alexa and Apple’s Siri relate information and field requests using a woman’s voice. Automated telephone directories don’t typically guide us along in deep baritones. It’s clearly not by chance. So why have companies chosen to treat AI美女视频黄频大全视频 as feminine?

In an opinion piece for , author Chandra Steele examined the idea of gender stereotypes playing a role. An Amazon spokesperson told Steele a female voice was what test users for Alexa responded to most strongly. For Microsoft’s Cortana, the company said it found a female voice to best embody the qualities expected of the digital assistant—helpful, supportive, and trustworthy. It’s been that both men and women generally warm to a female voice, whereas there’s more divisiveness when the voice is masculine.

美女视频黄频大全视频But the real reason may not be a result of contemporary biases or perceptions of women taking on administrative roles. Instead, it could be because of outdated notions. When designing Google Assistant, Google  it wanted to offer both male and female options and then realized how technologically difficult that would be. Why? Text-to-speech systems were trained mostly on female voices.

There are other possibilities. Some researchers believe women tend to articulate vowel sounds more clearly, or that the pitch of a woman’s voice is easier to hear. While these are tenuous arguments, they may have been behind the decision to use women in early developmental efforts.

There are, of course, exceptions. Many devices, including Siri, offer the option to switch between male and female voices. But it may take more than a toggle switch to outpace gender biases.
