Dolly the Sheep was cloned from an adult somatic cell using the process of somatic cell nuclear transfer at the Roslin Institute. [Memory Trick: Dolly the sheep was a 'Doll' of genetic science, a perfect copycat!]
The Mars Orbiter Mission (MOM), colloquially known as Mangalyaan, made India the first nation to reach Mars on a maiden attempt. [Memory Trick: 'MOM' loves us and showed the path to Mars with the ultimate budget efficiency!]
SONAR uses sound propagation underwater to navigate, communicate, or detect other vessels. [Memory Trick: 'SO-und' 'NA-vigation' 'a-nd' 'R-anging' = SONAR!]
Gaganyaan is designed to send a crew of three astronauts to an orbit of 400 km for a three-day mission and bring them back safely. [Memory Trick: 'Gagan' means sky or firmament; 'Gagan-yaan' is our vehicle ('yaan') to carry humans into the cosmic sky!]
Standard single-layer Blu-ray discs store 25 GB of high-definition digital data, while dual-layer variants store 50 GB. [Memory Trick: Blu-ray has more space than a DVD (4.7 GB) by nearly 'five fold' = 25 GB!]
NavIC (Navigation with Indian Constellation) consists of a constellation of 7 active satellites providing position accuracy over India and 1500 km around it. [Memory Trick: 'NavIC' sounds like 'Navik' (sailor), guiding Indian ships across regional waters!]
BARC is India's premier nuclear research facility, headquartered in Trombay, Mumbai, Maharashtra. [Memory Trick: Dr Bhabha's grand research center was planted directly near the shores of 'Trombay' in Mumbai!]
Silver Iodide (AgI) has a crystalline structure highly similar to natural ice, acting as an efficient catalyst for condensation. [Memory Trick: A 'Silver' spray in the high clouds brings 'gold'-en rain down!]
Dakshin Gangotri was the first Indian scientific research station established in Antarctica, later succeeded by Maitri and Bharati. [Memory Trick: The holy river of ice originating in the far 'Dakshin' (South Pole) = 'Dakshin Gangotri'!]
According to Einstein's General Relativity, gravity curves spacetime; clocks closer to a heavy mass tick slower than clocks in space. [Memory Trick: Heavy 'Gravity' slows things down, so up in weaken gravity, clocks 'dial up' and tick faster!]
Leptons are elementary particles with no strong interactions. Electrons and neutrinos are classic examples of leptons. [Memory Trick: Leptons are 'lightweight' ('lepto') particles, unlike bulky protons made of quarks!]
The Arjun Main Battle Tank (MBT) is a third-generation battle tank developed indigenously by DRDO for the Indian Army. [Memory Trick: Just like combat archer 'Arjun', this tank hits its target bullseye of incoming threats!]
Unlike traditional viruses, a 'Worm' is self-replicating and can travel across network links completely on its own. [Memory Trick: A 'Worm' crawls from brick to brick (system to system) through network cracks without you touching it!]
Somatic Cell Nuclear Transfer (SCNT) is the standard laboratory technique used to create cloned embryos for therapeutic or reproductive cloning. [Memory Trick: we take a regular base cell ('Somatic') to 'Transfer' its control center ('Nuclear') into an egg!]
JWST is an international collaboration led by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) to capture deep infrared space views. [Memory Trick: A massive project needing 'N'-ational 'A'-merican coordination with ocean-spanning 'S'-pace 'A'-llies!]
HTML stands for HyperText Markup Language, the backbone of any document displayed on a web browser. [Memory Trick: To weave a 'Text' web, you need 'HTML' tags to hold links!]
