I was unaware of the amorphous nature of pre-colonial caste system and the extent of colonial influence through creation of caste-based hierarchies of convenience!

Astronomical Unit in Hanuman Chalisa

- July 29, 2014

I had come across this forward message that made tall claims for hanuman chalisa. The forward read as follows: Any one knows the Hanuman chalisa? In Hanuman Chalisa, it is said : "Yug sahastra yojan per Bhanu! Leelyo taahi madhur phal janu!!" 1 Yug = 12000 years 1 Sahastra = 1000 1 Yojan = 8 Miles Yug x Sahastra x Yojan = par Bhanu 12000 x 1000 x 8 miles = 96000000 miles 1 mile = 1.6km 96000000 miles = 96000000 x 1.6km = 1536000000 km to Sun NASA has said that, it is the exact distance between Earth and Sun (Bhanu). Which proves Hanuman ji did jump to Planet Sun, thinking it as a sweet fruit (Madhu phal). It is really interesting how accurate and meaningful our ancient scriptures are..Unfortunately it is barely recognized. The estimate of 1 astronomical unit (au) - the distance between earth and sun has a long history. The first estimate only came during the transit of Venus in the 18th century. Before this event, we did not have any estimate for the ...

Does Rigveda convey the speed of light?

- January 01, 2021

In the commentary on the Rig Veda by Saayanacharya, a line translates as "Salutations to Sun-god who travels 2202 Yojanas in half a Nimisha". Some proponents interpret this to conclude that people during vedic age knew the accurate speed of light. We will now discuss the accuracy of this claim. This is how they come to this surprising conclusion.

Adhika masa and Kshaya masa

- January 18, 2012

This article is regarding the concept of Adhikamasa and Kshayamasa (intercalary months) used in some luni-solar calendars in India. Luni-solar calendars are in vogue since lunar months determine the high and low tides while the solar year determines the seasons. But the use of luni-solar calendars create a unique problem. Since the lunar year (12 lunar months) lags behind the solar year (~365.25 days), this creates a need to keep the lunar year and the solar year in synchrony. Hence the need to use Adhika masa (extra month) and Kshaya masa (removed month)! The reason for their asynchrony is explained next.

Myths about the Anti Corruption Movement

- April 09, 2011

In this article, I wish to discuss and demystify few important myths surrounding the anti-corruption movement led by Anna Hazare backed by India Against Corruption . Myth : Objective of the movement is to bypass the parliament and enact jan lokpal bill and hence anti-parliamentary in nature. This is the single biggest misconception that many people on both sides have. The movement was to ensure that the strong effective Lokpal bill is tabled in the parliament at the earliest and enacted.

Tree identification

- March 01, 2020

I attended a few sessions on Tree Identification during different seasons organised by Natural History Society of Northumbria ( NHSN ). These were guided walks lasting a couple of hours led by tree experts. These were amazing sessions where the enthusiasm of the guides were matched by us inquisitive participants. We covered basic aspects of tree identification, their ecological niche, interconnections in the ecosystem, utility to humans over time. Here are the visual guides to tree identification for summer and

Meaningful Birthday song

- March 01, 2025

The "happy birthday" song that we sing on someone's birthday is quite prosaic, dull, and repetitive to say the least. Maybe it it so because it addresses the lowest common denominator i.e. children who are yet to learn a language fully. If so then it is not for the adults to also sing the same song. Here is a meaningful birthday song in Sanskrit with its meaning. Song in Sanskrit: अयि प्रिय सखे जन्मदिनमिदम् । प्रार्थयामहे भव शतायुषी ॥ १ ॥ पुण्य कर्मणा कीर्तिमार्जय । जीवनम् तव भवतु सार्थकम् ॥ २ ॥ Transliteration of the poem: ayi priya sakhē janmadinamidaṃ । prārthayāmahē bhava śatāyuṣī ॥ 1 ॥ puṇya karmaṇā kīrtimarjaya । jīvanaṃ tava bhavatu sārthakam ॥ 2 ॥ Translation in English: Oh dear friend, today is your birthday; We all pray for your long life. By noble deeds may you attain fame; May your life be meaningful. Credits : [x] Original Birthday Song in Sanskrit by Swami Tejomayanandaji Link - https://www.chinmayajyoti.org/documents/birthdaysong.pdf

Sethuram: Kannada Stalwart

- October 04, 2021

S N Sethuram has authored couple of novels - Navalla and Dahana - apart from many short stories. He has written and directed theatre plays - Nimitta, Gathi, Atheeta, and Uchchista - as well as written the screenplay and directed few television serials - Manthana, Dibanna, and Anavarana - for which he became most famous amongst people of Karnataka state (India). Personally, I consider Sethuram as a stalwart of Kannada literature in the 21st century. Here is why. I like the depth of human emotions that he plumbs in his works. He holds a mirror to the society in his works and makes us question our values in our life. Though all his works are in Kannada, his stories transcend cultural barriers.

14th Summer School on ‘Brain Disorders Research’

- August 01, 2024

The annual Summer School on ‘Brain Disorders Research’ [1] is organised by Centre for Neuropsychiatric Genetics and Genomics (CNGG) [2], Cardiff University. This year the fourteenth edition of the summer school was held on July 8-11, 2024 in Cardiff, Wales. Here, I am documenting brief learnings and my reflections on participating in this summer school. The participants consisted of both students and researchers from neuroscience, and bioinformatics background as well as clinicians who were mainly trainee psychiatrists. We had participants from as far as HongKong and China who came to the UK just to participate in this program. Given this heterogeneous mixture in the audience, the organisers ensured that sufficient background information is shared before introducing new topics be it neuroimaging or genomics. Since I do not have a background in bioinformatics, this introductory information on it was very important to understand and relate to the state of the art research findings t...

Estimating age of a star cluster

- May 02, 2011

How can we determine the age of a star cluster using its H-R diagram. Background Star Clusters are groups of stars that are gravitationally bound ranging from just ten to over ten million in number e.g. Pleiades cluster (Krittika) or M45 in Taurus constellation. An H-R diagram is a scatter plot of Luminosity vs. surface temperature or absolute magnitude vs. spectral type of stars. Main sequence is the track of stars that runs diagonally across the H-R diagram from high luminosity, hot stars to low luminosity, cool stars. Need The star clusters are useful in checking theories of stellar evolution, for calibrating absolute luminosities, and
