1. NAKSHA

• NAtional geospatial Knowledge based land Survey of urban HAbitations

• city survey under Digital India Land Records Monetization Programme (DILRMP)

• u/ Mo Rural Development to create accurate geospatial maps of towns/cities of India

• Need:

- outdated & fragmented land records in India

- Inefficient governance delivery, land disputes, tax collection etc.

• Funding: 100% centrally funded w/ pilot project at ₹194 cr

2. Majorana-1 Quantum chip

• Made of topoconductor: special category material made of new state of matter (not solid, liquid, gas)

• Made of Indium, Arsenide & Aluminum (designed and fabricated atom by atom in 17 years🤯)

• 1/100th of millimetre; clear path to million-qubit processor (potential to break down microplastics or create self-healing materials)

3. Quasi-stellar radio source (QUASARS)

• Highly luminous & energetic Active Galactic Nucleus powered by supermassive black hole(s)

• emit intense X-rays w/ visible light making it brightest & most powerful objects in universe

• Identified in 1960s as star-like object(s) w/ significant redshift indicating their far off distance & old age in universe
