Fernando de Rojas. The most famous aphorisms

  • Money can do anything: it tears down rocks, it dries up rivers, there is no peak that a donkey loaded with gold could not climb.
  • Money does not bring wealth, but only anxiety.
  • Indecisiveness is worse than a failed attempt: water is less spoiled when flowing than when standing still.
  • No one is so old as not to be able to last another year, no one is so young as not to die today.
  • No one keeps a secret better than the one who does not know it.
  • The first step to madness is to imagine yourself a sage.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

diamond diode 22.05.2006

British scientists have made a transistor from amorphous carbon.

Semiconductors based on an amorphous substance, such as amorphous silicon, promise to revolutionize electronics by making huge, cheap, flat-panel monitors. After all, such a microcircuit does not need to be placed on a piece of a single crystal, which means that its size is practically unlimited. Unfortunately, electrons move too slowly through a grid of disordered atoms, and the gigahertz speeds required for good displays are beyond their strength.

However, as it should be, in addition to the direct path, a roundabout one also leads to the cherished goal. It's called a "resonant tunnel diode". Such a microcircuit consists of nanometer-thick layers in which quantum phenomena begin to play an important role. For example, electrons can move between layers due to the tunnel effect. In a three-layer structure, such movements can be controlled by changing the composition and thickness of the layers and obtain regions with negative resistance.

This effect has been repeatedly observed in crystalline microcircuits based on gallium arsenide, and physicists from the University of Surrey (Great Britain) under the guidance of Professor Ravi Silva managed to achieve it on an amorphous structure. In their experiments, they did not use silicon, but diamond-like films of carbon. Until recently, this material was exotic, but now scientists in many laboratories have learned how to work with it.

Moreover, diamond-like coatings can be deposited at room temperature on flexible and cheap plastic substrates. By themselves, the layers of such a coating are distinguished by chemical and mechanical resistance.
