Welcome to our “Science Tank” section. In this area of the website, we deal with relevant discoveries from the world of science (physics, mathematics, computer science, medicine and many more) in an interdisciplinary manner. We publish important achievements from around the world with a special focus on the scientific environment in Göttingen. Have fun and stay curious.
Today we received a YouTube video that we do not want to withhold from you. The video is a little older, namely 12 years old, so some of you may know it. It was published by Daniel Springwald and embodies exactly the spirit of "Star Trek Today". Mr. Springwald has done a remarkable job that deserves the highest respect. Better implementation of LCARSDesign and functionality is hard to find. He also publishes his work on his homepage "http://www.springwald.de/lcarshome". Have fun with the video!
Collisions between high energy protons allowed the view of unusual hyperons for the first time. They are counted among the foreign particles. They are baryons that contain at least one odd quark. Hyperons are likely to be found in the nuclei of neutron stars, so examining them could reveal a lot about the stars themselves and the environment with such extremely packed matter.
Are hyperons Hadrons, ie particles that consist of at least two quarks. Interactions between hadrons take place through strong interactions. We don't know much about the interactions between hadrons, and most of that knowledge comes from studies using protons and neutrons. The nature of the strong interactions makes them very difficult to make theoretical predictions about. It is therefore difficult to study theoretically how hadrons interact with one another. Understanding these interactions is often referred to as the "final frontier" of the Standard Model.
AI computer systems are finding their way into many areas of our lives and offer great potential, from self-driving vehicles to assisting doctors with diagnoses to autonomous search and rescue robots.
However, one of the major unsolved problems, especially with the branch of AI known as "neural networks", is that scientists often cannot explain why things go wrong. This is due to a lack of understanding of the decision-making process within AI systems. This problem is known as the "black box" problem.
Who is smarter?
A new 15-month research project from the University of Lancaster, in which the University of Liverpool is also involved, aims to unlock the secrets of the black box problem and find a new way to "Deep Learning"of AI computer models that make decisions transparent and explainable.
The project "Towards responsible and explainable autonomous robotic learning systems"will develop a series of security verification and test procedures for the development of artificial intelligence algorithms. These will help ensure that the decisions made by the systems are robust and explainable.
The MBN channel on South Korean cable television has presented the first female presenter, who is simultaneously from one artificial intelligence is controlled. The AI moderator by the name of AI Kim is based on a real person who operates an information segment in the MBN, Jim Ju-ha. AI Kim himself recently introduced himself and said that she came about from watching Kim Ju-ha's ten hour videos. The KI learned the details in her voice, her way of speaking, her facial expressions, lip movements and body language. Artificial intelligence says: "I am able to convey messages just like Kim Ju-ha.
The NASA and her partners are working on nuclear propulsion for spacecraft. The idea for atomic rocket engines came about in the 1940s. But only now do we have the technology that will make the concept of interplanetary, nuclear-powered travel a reality.
It is very important that the ideas that the NASA works, involve the use of nuclear engines outside the earth. The vehicles are to be started with chemical fuel engines and the nuclear engine is to start only outside of low earth orbit.
The greatest challenge was and is to design a safe and lightweight nuclear drive. This is ensured by new fuels and reactors. So high are the hopes for them that NASA is even considering manned missions using atomic decay energy. "Nuclear propulsion will be very useful if we think about traveling to and from Mars in less than two years," said Jeff Sheehy, chief engineer of the Space Technology Mission Directorate. The biggest challenge is making the right progress on fuel, he adds. Such a fuel would have to withstand very high temperatures and drive conditions. The two companies NASA works with make sure they have the right fuel and reactor.
Just as the metronome sets the tempo for the musician, the fundamental space clock set the time in the universe, claim theoretical physicists in their latest publication. But if such a clock exists, then it is ticking they extremely quickly. In physics, time is usually considered the fourth dimension, but some physicists speculate that it may be the result of some physical process, like the ticking of a built-in clock. If the universe has such an elementary clock, it must strike faster than a fifth of the time per second ((10 (to 33) - one and 33 zeros in decimal notation), according to a theoretical study published in Physical Review Letters has been published. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.124.241301
In particle physics, small fundamental particles can achieve certain properties through interaction with other particles or fields. Particles gain mass, for example by interacting with one Higgs field, a kind of molasses that permeates the whole room. Perhaps molecules can also experience time by interacting with a similar type of field, "says physicist Martin Bojowald. This field can oscillate (sway and vibrate), and each such cycle serves as a simple" tick "- just like in ordinary, traditional clocks "says Bojowald, co-author of the study.
A team of scientists from the University of Lancaster in Great Britain has developed a new method of storing solar energy for up to several months and releasing it as heat when needed. In other words: "reserves" of energy "for the winter" are created on warm sunny days. In theory, the method enables apartments and offices to be additionally heated, which significantly reduces environmental pollution.
The researchers have an organometallic skeleton (known as a MOF), which consists of metal ions combined in 3D structures. The molecules in the pores of these structures are able to absorb UV light and can change their shape when exposed to light or heat. Azobenzene particles - a light absorbing compound (in this case) - can at room temperature Remain trapped until outside heat is added to change it. Tests have shown that the material is able to store energy for more than four months.
The Korean "artificial sun" known as KSTAR extension, is a special fusion reactor. The scientists set a new world record by keeping the plasma at ion temperatures of over 20 million degrees Celsius for 100 seconds. The previous performance of this type was more than twice as short. KSTAR extension (Acronym for Korea Superconducting Tokamak Advanced Research) is a special one Fusion reactor, which is also called the Korean artificial sun. It is a very complex machine that makes it possible to reproduce fusion reactions that take place in the stars.
The new precision record for atomic clocks belongs to a team of scientists at the Massachusetts Institute of Technology working on the phenomenon of Quantum entanglement based method to have used a to create super accurate device. The performance and work is described in an article published in Nature.
Structures that are generated by gravitational interactions in the solar system enable objects to move quickly in space - scientists inform. The newly discovered route network can be used for your own space exploration.
Scientists have discovered a previously unknown network of cosmic "highways" that allow us to travel through the solar system much faster. Such routes could allow comets and asteroids near Jupiter to reach Neptune in less than a decade. You can have up to 100 astronomical units travel in less than a century. Newly discovered routes can be used to send spacecraft relatively quickly into the most remote corners of our planetary system and to observe and understand objects that could collide with our planet.
