Singh set this record when he scored five goals in India's 6–1 victory over the Netherlands in the gold medal game of the 1952 Olympic Games.

About: Cicadas are insects that spend most of their lives underground and emerge from the soil mainly to mate. Once out of the ground, their life span is fairly short, somewhere between two-four weeks. The insects are found in the America’s as well as New Zealand and Australia. There will be major outbreaks of periodical cicadas in 2020 and 2021. There are three species of 17-year cicadas and three species of 13-year cicadas. The name 13 and 17 year refers to the number of years that cicada nymphs take to reach adulthood. It is not clear why their development period is so long. After emerging from the ground in billions, the cicadas shed their exoskeletons or outer skins to take their winged form. The lifespan of adult cicadas is short, about two to four weeks during which time they feed relatively little and mate. This year, the grouping dubbed Brood IX will emerge after spending 17 years underground, into states including Southwest Virginia, parts of North Carolina and West Virginia. The emergence of over 1.5 million cicadas per acre is expected.

Though it was widely believed that the mystic poet was born in Purandharagad, Maharashtra, many in Malnad claim that he hailed from the region. About: Purandara Dāsa (1484 – 1565) of Haridasa movement, was a renowned composer of Carnatic music, a Vaishnava poet, a saint and a social reformer. He was a disciple of the Dvaita philosopher-saint Vyasatirtha. His guru, Vyasatirtha, glorified Purandara Dasa in a song thus: Dāsarendare purandara dāsarayya. Purandara Dasa was a wealthy merchant of gold, silver and other miscellaneous jewellery from Karnataka, who gave away all his material riches to become a Haridasa (literally meaning a servant of Lord Hari or Lord Krishna). As a devotional singer who made the difficult Sanskrit tenets of Srimad Bhagavatam available to everyone in simple and melodious songs. He formulated the basic lessons of teaching Carnatic music by structuring graded exercises known as Svaravalis and Alankaras, and at the same time, he introduced the raga Mayamalavagowla as the first scale to be learnt by beginners in the field – a practice that is still followed today. In honour of his significant contributions to Carnatic music, he is widely referred to as the "father" of Carnatic music. Purandara Dasa is noted for composing Dasa Sahithya, as a Bhakti movement vocalist, and a music scholar.

The magnetic field of the earth protects us from the solar radiation. South Atlantic Anomaly (SAA): However, a rapid shrink has been observed in the South Atlantic Anomaly (SAA), a stretch between Africa and South America. It is an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface, dipping down to an altitude of 200 kilometres. This leads to an increased flux of energetic particles in this region and exposes orbiting satellites to higher-than-usual levels of radiation. The effect is caused by the non-concentricity of the Earth and its magnetic dipole. The SAA is the near-Earth region where the Earth's magnetic field is weakest relative to an idealized Earth-centered dipole field. Pole reversal: One most speculated reason behind this is that there is a chance that the time for Earth's pole reversal is coming near. Pole reversal is when the north and south magnetic poles flip. While this flip will not occur immediately or suddenly, and will happen over centuries, there would be multiple north and south magnetic poles during this period, all around the planet. This is definitely not the first time that pole reversal will be happening on the Earth. This event has occurred few times in the history of our planet, as per the scientists and we are long overdue by the average rate at which these reversals take place (roughly every 250,000 years). Impact: This is not going to affect or alarm the general public to a huge extent. But it is causing technical difficulties for various satellites and spacecrafts, as the magnetic field getting weaker, charged particles from the cosmos can penetrate through to the altitudes that low-Earth orbiting satellites fly at.

India-China border is divided into three sectors:The LAC in the western sector falls in the union territory of Ladakh and is 1597 km long, The middle sector of 545 km length falls in Uttarakhand and Himachal Pradesh, and The 1346 km long eastern sector falls in the states of Sikkim and Arunachal Pradesh. The main differences are in the Western and Eastern sectors. India sees China as occupying 38,000 sq km in Aksai Chin. In the east, China claims as much as 90,000 sq km, extending all across Arunachal Pradesh. The middle sector is the least disputed sector, while the western sector witnesses the highest transgressions between the two sides.
