Jawaharlal Nehru. The most famous aphorisms

  • Without peace, all our dreams fade and turn to ashes.
  • When we find ourselves in a crisis or at an impasse, at least one thing pleases: this situation makes us think.
  • Our main disadvantage is that we are more inclined to discuss things than to do them.
  • You can't change the course of history by hanging all the portraits facing the wall.
  • Wounds inflicted by one's own hand always heal more slowly than those inflicted by the enemy.
  • Freedom and power require responsibility.
  • Who we really are is ultimately far more important than what people think of us.
  • The person who talks a lot about his own virtues is often the least virtuous.

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 ... >>

Temperature sensor TMP107 22.11.2016

The new TMP107 temperature sensor supports up to 32 devices in series. A chain of TMP107 sensors is connected to the microcontroller via one single-wire UART interface.

Each sensor has a unique 5-bit address stored in electrically erasable programmable memory (EEPROM). The address is assigned during the auto assignment operation and is based on the position of each sensor in the chain. The transmission distance of the UART bus can be up to 300 meters. Data is transmitted between sensors using the proprietary SMAART Wire protocol.

The TMP107 provides maximum flexibility in use, allowing you to choose between low power consumption (e.g. when running on batteries) and high refresh rates for real-time applications.

The warning function of the TMP107 is implemented with two registers for storing programmable values ​​for low and high temperatures. After each measurement, the temperature is compared with the values ​​from these registers. When the specified range is exceeded, the sensor sends a corresponding signal, which can be processed by the microcontroller or displayed on the alarm warning LED.

The TMP107 is capable of reading temperature with a resolution of 0,015625°C and an accuracy of +-0,4°C in the range from -20°C to +70°C. This sensor is ideal for replacing NTC and PTC thermistors in applications requiring high measurement accuracy, such as industrial, medical, environmental, and grain storage temperature control systems.

The TMP107 is housed in a SOIC-8 package and is designed for use in a temperature range of -55°C to +125°C.

Features:

High accuracy:
+-0,4°C (max.) at -20°C to +70°C;
+-0,55°C (max.) at -40°C to +100°C;
+-0,7°C (max.) at -55°C to +125°C;
High resolution: 14 bits (0,015625°C);
UART-compatible wired SMAART interface;
Support up to 32 serial devices;
EEPROM for unique addressing, programmable values, general purpose data storage;
Continuous operation and shutdown mode to save energy;
Single conversion mode for energy saving;
Programmable warnings;
Temperature range: -55°C to +125°C;
Voltage range: 1,7 to 5,5V;
Chassis: SOIC-8.

Applications:

Refrigerators and refrigerating chambers;
Distributed temperature measurements;
Thermal protection of power supplies and batteries;
Servers and telecommunication systems;
Building automation;
Agricultural machinery;
Medical instruments;
Industrial systems.
