Earlier this month, Bobby McFerrin and a cast of 20 incredible singers from around the world dazzled the Stimmen Festival in Basel with their performance of Bobble, Bobby’s new improvised opera with a wordless libretto. The performance retells and reimagines the biblical tale of the Tower of Babel, and our endless search for common language and true communication. This beautiful photo was taken by the Festival’s Artistic Director, Helmut Bürgel.
Lunar clockwork What scientists know for certain is that they need to get precision timekeeping instruments to the moon. Кракен тор Exactly who pays for lunar clocks which type of clocks will go and where they’ll be positioned are all questions that remain up in the air Gramling said. “We have to work all of this out” she said. “I don’t think we know yet. I think it will be an amalgamation of several different things.” https://kra30c.cc kraken сайт Atomic clocks Gramling noted are great for long-term stability and crystal oscillators have an advantage for short-term stability. “You never trust one clock” Gramling added. “And you never trust two clocks.” Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit. As for price an atomic clock worthy of space travel could cost around a few million dollars according Gramling with crystal oscillators coming in substantially cheaper. But Patla said you get what you pay for. “The very cheap oscillators may be off by milliseconds or even 10s of milliseconds” he added. “And that is important because for navigation purposes — we need to have the clocks synchronized to 10s of nanoseconds.” A network of clocks on the moon could work in concert to inform the new lunar time scale just as atomic clocks do for UTC on Earth. There will not Gramling added be different time zones on the moon. “There have been conversations about creating different zones with the answer: ‘No’” she said. “But that could change in the future.”
New design revealed for Airbus hydrogen plane renzo In travel news this week: Bhutan’s spectacular new airport the world’s first 3D-printed train station has been built in Japan plus new designs for Airbus’ zero-emission aircraft and France’s next-generation high-speed trains. Grand designs European aerospace giant Airbus has revealed a new design for its upcoming fully electric hydrogen-powered ZEROe aircraft. powered by hydrogen fuel cells. The single-aisle plane now has four engines rather than six each powered by their own fuel cell stack. The reworked design comes after the news that the ZEROe will be in our skies later than Airbus hoped. The plan was to launch a zero-emission aircraft by 2035 but now the next-generation single-aisle aircraft is slated to enter service in the second half of the 2030s. Over in Asia the Himalayan country of Bhutan is building a gloriously Zen-like new airport befitting a nation with its very own happiness index. Gelephu International is designed to serve a brand new “mindfulness city” planned for southern Bhutan near its border with India. In rail travel Japan has just built the world’s first 3D-printed train station which took just two and a half hours to construct according to The Japan Times. That’s even shorter than the whizzy six hours it was projected to take. France’s high-speed TGV rail service has revealed its next generation of trains which will be capable of reaching speeds of up to 320 kilometers an hour nearly 200 mph. The stylish interiors have been causing a stir online as has the double-decker dining car. Finally work is underway in London on turning a mile-long series of secret World War II tunnels under a tube station into a major new tourist attraction. CNN took a look inside.
‘A whole different mindset’ Accurate clockwork is one matter. But how future astronauts living and working on the lunar surface will experience time is a different question entirely. kraken сайт On Earth our sense of one day is governed by the fact that the planet completes one rotation every 24 hours giving most locations a consistent cycle of daylight and darkened nights. On the moon however the equator receives roughly 14 days of sunlight followed by 14 days of darkness. “It’s just a very very different concept” on the moon Betts said. “And NASA is talking about landing astronauts in the very interesting south polar region of the moon where you have permanently lit and permanently shadowed areas. So that’s a whole other set of confusion.” https://kra30c.cc kra30cc “It’ll be challenging” for those astronauts Betts added. “It’s so different than Earth and it’s just a whole different mindset.” That will be true no matter what time is displayed on the astronauts’ watches. Still precision timekeeping matters — not just for the sake of scientifically understanding the passage of time on the moon but also for setting up all the infrastructure necessary to carry out missions. The beauty of creating a time scale from scratch Gramling said is that scientists can take everything they have learned about timekeeping on Earth and apply it to a new system on the moon. And if scientists can get it right on the moon she added they can get it right later down the road if NASA fulfills its goal of sending astronauts deeper into the solar system. “We are very much looking at executing this on the moon learning what we can learn” Gramling said “so that we are prepared to do the same thing on Mars or other future bodies.”

Space time: The continual question If time moves differently on the peaks of mountains than the shores of the ocean you can imagine that things get even more bizarre the farther away from Earth you travel. kraken вход To add more complication: Time also passes slower the faster a person or spacecraft is moving according to Einstein’s theory of special relativity. Astronauts on the International Space Station for example are lucky said Dr. Bijunath Patla a theoretical physicist with the US National Institute of Standards and Technology in a phone interview. Though the space station orbits about 200 miles 322 kilometers above Earth’s surface it also travels at high speeds — looping the planet 16 times per day — so the effects of relativity somewhat cancel each other out Patla said. For that reason astronauts on the orbiting laboratory can easily use Earth time to stay on schedule. https://kra30c.cc кракен онион For other missions — it’s not so simple. Fortunately scientists already have decades of experience contending with the complexities. Spacecraft for example are equipped with their own clocks called oscillators Gramling said. “They maintain their own time” Gramling said. “And most of our operations for spacecraft — even spacecraft that are all the way out at Pluto or the Kuiper Belt like New Horizons — rely on ground stations that are back on Earth. So everything they’re doing has to correlate with UTC.” But those spacecraft also rely on their own kept time Gramling said. Vehicles exploring deep into the solar system for example have to know — based on their own time scale — when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes she added. For 50 years scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites which orbit Earth about 12550 miles 20200 kilometers away — or about one-nineteenth the distance between our planet and the moon. Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon Patla said. “We can easily compare GPS clocks to clocks on the ground” Patla said adding that scientists have found a way to gently slow GPS clocks down making them tick more in-line with Earth-bound clocks. “Obviously it’s not as easy as it sounds but it’s easier than making a mess.”

Mist and microlightning solflare To recreate a scenario that may have produced Earth’s first organic molecules researchers built upon experiments from 1953 when American chemists Stanley Miller and Harold Urey concocted a gas mixture mimicking the atmosphere of ancient Earth. Miller and Urey combined ammonia NH3 methane CH4 hydrogen H2 and water enclosed their “atmosphere” inside a glass sphere and jolted it with electricity producing simple amino acids containing carbon and nitrogen. The Miller-Urey experiment as it is now known supported the scientific theory of abiogenesis: that life could emerge from nonliving molecules. For the new study scientists revisited the 1953 experiments but directed their attention toward electrical activity on a smaller scale said senior study author Dr. Richard Zare the Marguerite Blake Wilbur Professor of Natural Science and professor of chemistry at Stanford University in California. Zare and his colleagues looked at electricity exchange between charged water droplets measuring between 1 micron and 20 microns in diameter. The width of a human hair is 100 microns. “The big droplets are positively charged. The little droplets are negatively charged” Zare told CNN. “When droplets that have opposite charges are close together electrons can jump from the negatively charged droplet to the positively charged droplet.” The researchers mixed ammonia carbon dioxide methane and nitrogen in a glass bulb then sprayed the gases with water mist using a high-speed camera to capture faint flashes of microlightning in the vapor. When they examined the bulb’s contents they found organic molecules with carbon-nitrogen bonds. These included the amino acid glycine and uracil a nucleotide base in RNA. “We discovered no new chemistry; we have actually reproduced all the chemistry that Miller and Urey did in 1953” Zare said. Nor did the team discover new physics he added — the experiments were based on known principles of electrostatics. “What we have done for the first time is we have seen that little droplets when they’re formed from water actually emit light and get this spark” Zare said. “That’s new. And that spark causes all types of chemical transformations.”

Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility safepal wallet In the 1931 movie “Frankenstein” Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and energy crackled Frankenstein’s monster stirred on a laboratory table its corpse brought to life by the power of electricity. Electrical energy may also have sparked the beginnings of life on Earth billions of years ago though with a bit less scenery-chewing than that classic film scene. Earth is around 4.5 billion years old and the oldest direct fossil evidence of ancient life — stromatolites or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old. However some scientists suspect life originated even earlier emerging from accumulated organic molecules in primitive bodies of water a mixture sometimes referred to as primordial soup. But where did that organic material come from in the first place? Researchers decades ago proposed that lightning caused chemical reactions in ancient Earth’s oceans and spontaneously produced the organic molecules. Now new research published March 14 in the journal Science Advances suggests that fizzes of barely visible “microlightning” generated between charged droplets of water mist could have been potent enough to cook up amino acids from inorganic material. Amino acids — organic molecules that combine to form proteins — are life’s most basic building blocks and would have been the first step toward the evolution of life.
Mindful wellness challenges If you’re the type of person who thrives on challenges and pushing your limits this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in take a step back and ask yourself if you’re pursuing the challenge for the right reasons McGregor said. velodrome finance Some people want to try these challenges because they believe something is missing from their life and they’re looking to attain “worth” or receive validation McGregor noted. A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason. Before trying any new trend make sure you have the foundation to handle it and be aware of any potential risks McGregor said. For casual runners this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges such as a marathon McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way. Focusing on sustainable habits Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges. Rather than chasing the idea of being “healthy” McGregor suggests focusing on actual healthful behaviors and starting small. If you’re a highly sedentary person and want to add more movement to your day try doing lunges while brushing your teeth or taking short walks throughout your typical routine.
