A Swiss man has shown that a parachute designed more than 500 years ago by Leonardo da Vinci works.
The 36-year-old parachutist made a successful 650-meter drop late last month. The parachute he used was made based on designs from a text by Leonardo.
“A perfect jump,” Olivier Vietti-Teppa said.

Vietti-Teppa is the first person to have made it safely to the ground with the Leonardo model. He jumped from a helicopter and the parachute opened at 600m.
The parachute was made using modern fabric. It consists of four equilateral triangles, 7m on each side. The base of the pyramid is a square of mosquito net, which enables the parachute to open.
One drawback is that it’s impossible to steer the Leonardo parachute. Vietti-Teppa said that “you come down at the whim of the wind.”
To test the parachute, Vietti-Teppa used a dummy launched from a remote-controlled model helicopter.

一名瑞士男子證實了五百多年前，由李奧那多．達文西設計的降落傘確實可「飛」。
上個月底，這名三十六歲的跳傘者成功地從六百五十公尺的高空跳下；他所使用的降落傘是根據達文西筆記中的降落傘設計圖製作而成。
奧立弗．維耶堤特帕說：「這是一次完美的跳傘。」
維耶堤特帕是用「達文西降落傘」平安著陸的第一人；他從一架直昇機上跳下，然後在距離地面六百公尺高處打開降落傘。
這具降落傘是用現代布料製成，由四個邊長七公尺的等邊三角形組成，金字塔底部是一個方形的蚊帳，這個設計讓降落傘可以順利展開。
「達文西降落傘」有一個缺點，就是跳傘者無法操控方向；維耶堤特帕說「你只能隨風飄」。
為了測試這具降落傘是否可行，維耶堤特帕先利用一具假降落傘和一架遙控模型直昇機進行演練。

Many consumers are guilty of filling drawers or closets with old laptops, cellphones, fitness trackers and other electronic devices once they are no longer needed. It’s hard to know where to recycle such items, or it seems costly and inconvenient to do so. The world generates millions of tons of electronic waste — also called e-waste — each year. According to the UN’s most recent estimate, people worldwide produced 62 million metric tons of e-waste in 2022, and only about 22 percent of it was properly recycled. The US’ Environmental Protection Agency estimates that less than a quarter of e-waste is
You’re sitting in class when a classmate asks to borrow a pencil. It seems like a small favor, so you agree without hesitation. The following week, the same classmate asks to share your notes. Later, they request help with a group project. You agree each time — after all, you helped out the first time — but before you know it, it has become automatic. This scenario demonstrates the “foot-in-the-door technique,” a psychological concept that shows how agreeing to small, acceptable demands makes it easier to accept larger ones later on. The name for this strategy comes from door-to-door
