What this high school senior wants adults to know about classroom phone bans <a href=https://sberlegal.ru>услуги по медиации онлайн сбербанк кредит ооо сберлигал обращение в сбербанк через интернет юридические консультации онлайн что такое оферта в сбербанке ооо сбер сбербанк юридическая помощь онлайн юрист юридическая помощь онлайн </a> When my friends and I walked into homeroom on the first day of school this year, my teacher told all of us to put our phones in a black plastic box on an old desk by the classroom door.
Handing over our phones during class is an official school policy, and my teachers always make this announcement at the beginning of the school year. But teachers would usually forget about the box by third period on the first day, never to be mentioned again by the second day of school. This year, however, the policy stuck that entire first day and every day since. I asked my Latin teacher why the school was suddenly getting so strict on phones. It turns out that over the summer most of the teachers had read social psychologist Jonathan Haidt’s book “The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness.”
Haidt, the Thomas Cooley Professor of Ehtical Leadership at New York University Stern School of Business, argues that a phone-based childhood leads to mentally unhealthy kids who are unprepared for life and, in my Latin teacher’s words, it “really freaked us out.” Teachers were serious about taking our phones now.
It’s not just causing trouble at my school. Some 72% of public high school teachers in the United States say that cell phone distraction among their students is a major problem, according to a study published by the Pew Research Center in April. In high schools that already have cell phone policies, 60% of teachers say that the policies are very or somewhat difficult to enforce, the same study reported.
Several states have passed laws attempting to restrict cell phone use in schools, and California Gov. Gavin Newsom recently signed legislation requiring school districts to regulate cell phone use. At least seven of the 20 largest school districts in the nation have either banned phones during the school day or plan to do so.

Automatic takeoffs are coming for passenger jets and they’re going to redraw the map of the sky <a href=https://krmp10.cc>kra10.cc</a>
In late 1965, at what’s now London Heathrow airport, a commercial flight coming from Paris made history by being the first to land automatically.
The plane A Trident 1C operated by BEA, which would later become British Airways was equipped with a newly developed extension of the autopilot (a system to help guide the plane’s path without manual control) known as “autoland.”
Today, automatic landing systems are installed on most commercial aircraft and improve the safety of landings in difficult weather or poor visibility.
Now, nearly 60 years later, the world’s third largest aircraft manufacturer, Brazil’s Embraer, is introducing a similar technology, but for takeoffs.
Called “E2 Enhanced Take Off System,” after the family of aircraft it’s designed for, the technology would not only improve safety by reducing pilot workload, but it would also improve range and takeoff weight, allowing the planes that use it to travel farther, according to Embraer.
“The system is better than the pilots,” says Patrice London, principal performance engineer at Embraer, who has worked on the project for over a decade. ”That’s because it performs in the same way all the time. If you do 1,000 takeoffs, you will get 1,000 of exactly the same takeoff.”
Embraer, London adds, has already started flight testing, with the aim to get it approved by aviation authorities in 2025, before introducing it from select airports.
