Current Context : A hundred million tonnes of nitrogen removed from the atmosphere and converted into fertilizer via the Haber-Bosch process, adding 165 million tonnes of reactive nitrogen to the soil. ABOUT HABER-BOSCH PROCESS: Purpose: It converts nitrogen (N₂) from the air and hydrogen (H₂) into ammonia (NH₃), a key component in fertilizers. Developers: Invented by Fritz Haber in the early 1900s. Industrialized by Carl Bosch, making it possible to mass-produce fertilizers. Significance: Enabled large-scale fertilizer production, supporting global agriculture. Considered one of the most important technological advances of the 20th century. Process: Nitrogen and hydrogen are combined under high pressure and moderately high temperatures. An iron-based catalyst is used to....Read More
Current Context : The Union Ministry of Earth Sciences has approved the installation of an X-band radar in Wayanad, Kerala, following severe floods and landslides. ABOUT X-BAND RADAR: Frequency Range: Operates in the 8-12 GHz range, allowing for high-resolution imaging. Applications: Monitors particle movements, such as soil, aiding in landslide warnings. Real-Time Monitoring: Capable of rapid sampling to detect changes in particle movement. Weather Observation: Useful for studying cloud development and light precipitation due to its ability to detect small water particles WHAT IS RADAR? Radar (Radio Detection and Ranging) uses radio waves to determine the distance, speed, and characteristics....Read More
Current Context : Recently, Taiwan’s navy commander Admiral Tang Hua claimed that the People's Liberation Army (PLA) is using an ‘anaconda strategy’ to squeeze the island nation. The 'Anaconda Plan' refers to a military and economic strategy aimed at constraining Taiwan by surrounding it with military resources, similar to an anaconda suffocating its prey. This strategy mirrors the original "Anaconda Plan" from the American Civil War, which aimed to suffocate an adversary without direct confrontation. Objective: To limit Taiwan’s access to international support and resources while maintaining strong naval capabilities in the region.Read More
