There is a proverb among amateur radio operators: When all other methods fail, there is amateur radio. This is true, at least to a certain extent—turn off the power, remove the phone lines, burn all the satellites in orbit, and there will still be hams talking about politics at 40 meters. The key is that as long as the laws of physics do not change, Ham will find ways to send and receive messages.To commemorate this fact, the police in Pune, Maharashtra, India specifically pointed out Use Morse code to exchange information with headquarters once a week. The idea is to maintain a backup system in case they cannot get the news through any other means. This is a good idea, especially because they rotated all radio operators through a Sunday morning ceremony. However, we cannot imagine that most emergency service dispatchers would be excited about learning Morse.
Just because you are a billionaire in an aerospace company does not mean you are an astronaut.At least that is Views of the Federal Aviation AdministrationWhen Jeff Bezos and his happy team floated above the 100-kilometer Carmen Line on the Blue Origin “New Shepard” rocket, the guide almost issued guidelines. The FAA’s guidelines clearly state that those who take this trip need to actually do something to obtain astronauts by “demonstrating activities that are essential to public safety during the flight or that contribute to the safety of human space flight” Qualifications.This is good news “Old Shepard”, He apparently controlled “Freedom 7” during Project Mercury. But the Bezos brothers, teenagers Oliver Damen and Wally Funk (Wally Funk is a member of the “Mercury 13” group of women, they have received NASA astronaut training, but have never flown) really just In order to take a ride, because the entire flight is automated. This does not eliminate the fact that they have been to space and of course you have not, but they cannot officially call themselves astronauts. This shows that even billionaires can become ballasts.
Good news, everyone-if you have anything being transported from Ever Given, yours will arrive soon. The container ship that blocked the Suez Canal finally arrived at the original destination of Rotterdam, About four months later than originally expected. In March last year, after this important waterway was blocked for six days, the ship, along with her cargo and crew, was stranded in the Great Bitter Lake in Egypt, which may be the coolest body of water beside the Dead Sea in the world. At that moment there was a legal dispute, and all along, anything in the more than 20,000 containers on board has become meaningless. We can imagine that even with continuous electricity, everything in the refrigerated container must be dirty now, so there may be a lot of logistics and clean-up work to be solved.
I have to admit that I have a strange love for explosive bolts. I don’t know what it is, but the idea that the fastener design fails in a predictable manner under the influence of the pyrotechnic charge makes me feel a little itchy. I mean, I even wrote an entire article on this topic.So when i met This video explains how the space shuttle is fixed on the launch pad, I really have to watch. Surprisingly, the most interesting part of this story is not the explosive aspect, but the engineering problem supporting the huge vehicle on the launch pad. Although the space shuttles look elegant when they enter orbit, they are really clumsy beasts, especially tied to external fuel tanks and boosters. The size of the eight fragile nuts used to secure the booster to the mat is jaw-dropping. We also like the idea that NASA decided to collect explosive debris in a container full of sand.
