Toyota phát minh ra động cơ oto chạy bằng nước kìa 😁😁😁
Trong một bước di chuyển được thiết kế để phá vỡ ngành công nghiệp ô tô toàn cầu, Toyota vừa cho ra mắt một động cơ chạy nước dựa trên hydrogen được sản xuất bởi điện phân - và điều đó chỉ phát ra hơi nước! Không liti. Không có trạm sạc. Không có gì ngoài cuộc cách mạng thuần khiết. Với sự lựa chọn táo bạo này, Toyota không chỉ cạnh tranh với xe ô tô điện - nó đang tuyên bố kết thúc kỷ nguyên pin.

In the 1960s, a direct flight to Neptune would have taken nearly 30 years. That was longer than most spacecraft could survive. Reaching the outer planets seemed almost impossible.
But one engineer, working quietly with a pencil, found a way around this problem.
Gary Flandro, a scientist at NASA’s Jet Propulsion Laboratory, was asked to study how spacecraft might travel to the distant planets despite the limits of rocket technology at the time. Fuel was scarce, and engines were not powerful enough for such long journeys.
Flandro turned to a clever idea from physics called a gravity assist, sometimes known as a planetary slingshot. The concept is simple in principle. When a spacecraft passes close to a large planet, the planet’s gravity pulls it in and then flings it forward. In doing so, the spacecraft steals a tiny bit of the planet’s motion around the Sun. The planet slows down by an amount too small to notice, but the spacecraft gains a huge increase in speed without using any fuel.
With only paper, pencil, and the limited computers of 1965, Flandro calculated the future positions of Jupiter, Saturn, Uranus, and Neptune. What he found was remarkable. In the late 1970s, these giant planets would line up in a rare formation. This alignment would allow a single spacecraft to travel from one planet to the next, gaining speed at each step.
This opportunity appears only once every 176 years.
Flandro showed that a spacecraft could use Jupiter’s gravity to reach Saturn, then use Saturn to reach Uranus, and finally use Uranus to reach Neptune. This chain of boosts would cut the travel time to Neptune from about 30 years down to just 12.
This elegant piece of mathematics changed everything.
It became the foundation for the Voyager 1 and Voyager 2 missions, both launched in 1977. Thanks to this precise planning, the two spacecraft sent back the first close images of the outer planets. They later continued their journey beyond the solar system, becoming the first human-made objects to enter interstellar space.
All of it began with a simple insight, worked out by hand, that turned an impossible journey into a reachable one.
Nothing better than a summer Spielberg movie night in a packed theater with friends!
Steven thank you for all of the hours of joy that you have given us in the cinema!! It has been a great honor and pleasure to have worked with you and to call you my friend.
Congratulations to my dear friend Emily and the entire group of artists that created this movie. You were superb.
We all loved Disclosure Day!!
I wouldn’t be where I am today without the love and support that @MichelleObama has poured into me over the years. Her story — from her South Side roots to the White House and beyond — is a central part of the Obama Presidential Center.
El Papa León XIV ha bendecido la torre de Jesucristo, el acto central del Año Gaudí y uno de los hitos más significativos en la historia reciente de la Basílica. Con 172,5 metros de altura, esta torre se convierte en el punto más elevado de la Basílica y convierte la Sagrada Família en la iglesia más alta del mundo.
"В домах Шотландии делают специальные гнёзда для стрижей. Согласно закону, такие гнёзда должны быть во всех новостройках, где это «технически возможно». Так пытаются восстановить популяцию, которая из-за нехватки мест гнездования сократилась на 60% за 30 лет."

Director Steven Soderbergh during his interview with The Playlist revealed that he pitched ideas for James Bond films to producer Barbara Broccoli on two separate occasions, and both were ultimately rejected.
Soderbergh's proposal was for a parallel franchise. A separate Bond continuity or "universe" that would run alongside the main series. The pitch's key aspects were the following:
- Set in the 1960s
- R-rated, with more violence and sex
- A different actor as Bond
- A fictional backstory tied to real historical events
- A more stylized, auteur-driven approach

Based on conversations with Prime Minister Shehbaz Sharif and Field Marshal Asim Munir, of Pakistan, and wherein they requested that I hold off the destructive force being sent tonight to Iran, and subject to the Islamic Republic of Iran agreeing to the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz, I agree to suspend the bombing and attack of Iran for a period of two weeks. This will be a double sided CEASEFIRE! The reason for doing so is that we have already met and exceeded all Military objectives, and are very far along with a definitive Agreement concerning Longterm PEACE with Iran, and PEACE in the Middle East. We received a 10 point proposal from Iran, and believe it is a workable basis on which to negotiate. Almost all of the various points of past contention have been agreed to between the United States and Iran, but a two week period will allow the Agreement to be finalized and consummated. On behalf of the United States of America, as President, and also representing the Countries of the Middle East, it is an Honor to have this Longterm problem close to resolution. Thank you for your attention to this matter! President DONALD J. TRUMP
