EXPLANATION OF THE EXISTENCE OF DARK MATTER AND DARK ENERGY !

What Is Dark Energy ?

More is unknown than is known. We know how much dark energy there is because we know how it affects the universe's expansion. Other than that, it is a complete mystery.

Story of Metro Man E. Sreedharan

There are some builders who need to get everything right in the first go. They cannot fail for on them rests millions of hopes. They are the class of nation builders. One such great builder of modern India is the Metro Man E. Sreedharan.

After graduating from college, Sreedharan started preparing for Indian Railway Service Examination (IRSE) while supporting himself as a college lecturer.

With in a year results were out. Sreedharan had secured an all India IRES rank of 7th. Sreedharan rose quickly in Railways

to become the youngest divisional manager at the age of 26 years. G. P. Warrier, a stalwart in Railways, recognized the spark in Sreedharan and gave him early opportunities to work on Pampan Bridge and later on Calcutta metro project.

Pampan Bridge, an engineering marvel built by Britishers in 1914, connects the holy town of Rameshwaram to mainland India. The bridge suffered severe damages in the cyclone of 1964. Sreedharan was given an impossible task to make the bridge operational in 3 months. Cyclone had

washed all 126 girders. Sreedharan’s out of box thinking and his early tryst with Port Engineering came to his rescue. He fished all 126 girders from the sea using specially crafted cranes and skilled laborers finishing the repair project in record time.

THE SCIENCE BEHIND YAJNA

Fire is, of course, one of the greatest discovery of mankind. Our control over the fire dramatically changed the entire human habits; earlier it was used to cook food, protection from animals and to stay warm.

Among the many applications of fire, one is Yajna (यज्ञ, yajña); also called as Havana (हवन) or Agnihotra (अग्निहोत्र).
Yajna is elaborately described in Yajurveda. In Yajurveda, Yajna is the greatest among all works (Karman). One can purify his /her soul by performing Yajna.

In Vedic culture, it is thought that the holy fire is the mediator between Gods and us; when the offerings are made to Yajna with chanting mantras, it directly reaches the Gods, who bless the people with rains, food, health, and good luck.

According to Apastamba Sutra, the definition of Yajna is Vedic sacrifice; an act by which we surrender something for gods e.g. grains (Anna), pulse, milk and milk product (ghee, butter, curd) fruits, plant juice (soma), etc.

As we said; Yajna is the contact medium for gods and

to seek their blessings.

There are many types of Yajna performed by Hindus for e.g.,

1. Rajsuya Yajna
2. Ashwamedha Yajna
3. Chaaturmasya Yajna
4. Vaajpey Yajna
5. Purushmedha Yajna
6. Sarvamedha Yajna

YAGYOPAVEET - A FORM OF GAYATRI

Yagyopaveet ( wearing the sacred thread ) symbolises, in itself the realisation of the supreme truth behind the Gayatri Philosophy.

Gayatri mantra has 9 words, 3 Charans, 3 Vyahiritis and one Omkar so has the Yagyopaveet for it possesses 9 sutras, 3 threads, 3 knots and one supreme knot - the Brahma-Granthi . Since the Yagyopaveet lies over one's shoulders, chest, abdomen and back .

This signifies Divine control over shoulders, which undertake the heaviest responsibilities of life, over the heart which is supposed to be representing idealisms & emotions, over the abdomen where dwells the valour of a man and over the back, which represents alertness and

vigour . Thus, the influences that Gayatri excercises through Yagyopaveet on the total personality & endeavours of a man are never forgotten during entire life .

LESSER KNOWN PEOPLE OF INDIA - PART -2

#WomenDay2021 special

Posted in Bastar, Usha Kiran Is the First Woman Officer of the Elite Commando Force Cobra!

Don't forget to follow me @AKASHBH95801446

She Is The First Woman Officer From All Armed/Central Forces To Be Deployed In Counter Insurgency/Combat Operations.

She is the youngest female CRPF officer to be a part of Commando Battalion for Resolute Action (COBRA) and is currently serving the volatile region of Bastar

Usha is a third generation CRPF officer after her grandfather and father, so the passion for the forces naturally developed in her. “Getting into CoBRA was definitely my choice. I had this wish during my basic training at CRPF Academy Kadarpur Gurugram.

But it was an all male force at that time and no woman ever joined CoBRA,” she recalls, adding, “Soon after passing out of the Academy, I first decided to work in Chhattisgarh, and was fortunate enough to get a chance to serve in the Bastar region. During my year there,

I gained knowledge and confidence about CRPF’s counter insurgency operations and also got to practically know about the functioning of CoBRA. That’s when I decided to join the elite commando force,” says the former national athlete, who represented Delhi in triple jump.

DO U KNOW WHO WAS THE FOUNDER OF YOUR FAVOURITE CHILDHOOD MAG CHANDAMAMA

A boy was born in Pottipadu, a little-known village in Cuddapah district in Andhra Pradesh some 109 years ago. The village school taught only epics like the Ramayana, Mahabharata, and the Bhagavatam.

The teacher told the children how to lead a righteous life. They were advised to get by heart the truths contained in our ancient works.

The boy, Nagi Reddi, later moved to Madras (now Chennai), where he attended a regular school for a few years. Before he could complete

his studies, he was called upon to join the family export business. As a youth, he was drawn to the country's fight for independence. He got involved in the Khadi movement. But his presence was required in Burma (now Myanmar) to look after the business.

However, the business suffered huge losses during the
Second World War, and he had to start life afresh. He established a printing press which led to his publishing venture. He launched Andhra Jyothi, a socio-political magazine.

This venture brought about his close association with Shri Chakrapani, a writer of repute. Between the two of them they visualised a magazine that would entertain and educate the children of India speaking different language. It was a bold idea .

Announcing the 2021 Summer Institutes in Computational Social Science. #SICSS is for grad students, post-docs & beginning faculty. Free for participants. @chris_bail and I are happy to tell you about all 20 locations. https://t.co/wolhtZIMc5 [thread]

SICSS brings together social scientists & data scientists interested in computational social science for 1-2 week events with intensive study & collaborative research.

Topics covered include automated text analysis, web scraping, non-probability sampling, digital experiments, ethics & much more.

All education materials created for SICSS are available open-source so that people who are unable to participate can still learn. You can also use them in your teaching. Here are materials from previous years:

Because of COVID, all SICSS locations will be online only in 2021.

Highlights:
⚪️A Lab-on-a-Chip platform for organoids w/ wide capabilities: long-term culture | controlled & dynamic perifusion | in situ spatio-temporal imaging | serial cell assessment | ease of sample retrieval

⚪️Continuous fluidic flow increased local oxygen supply to islets in hydrogels & reduced cellular hypoxia
⚪️Flow increased cellular viability & reduced apoptosis & cell death

⚪️Human islets in hydrogels were highly functional during the 10 day in situ culture in our chips, while islet function was rapidly lost under static conditions
⚪️Glucolipotoxicity study showed a treatment window as small as 2.5 hours can elevate cell death

What are organoids? – A miniaturized version of an organ that imitate an aspect of human interface. They are commonly developed from stem cells in a lab. Human body also produces organoids naturally particularly within the pancreas.

11 BIG IDEAS OF PHYSICS

via @BlasMoros of @LTCWRK

(Thread 👇)

1. Galilean Relativity

We can never fully grasp, define, or understand a system we are part of.

“Distance provides perspective” and wisdom in life is often about perspective.

2. The Laws of Thermodynamics

The study of the large-scale behavior of systems exchanging work and heat with connected systems or their environment.

- The Transitive Law

- The Law of Conservation

- The “Contrast Advantage” Law

- The “Absolute Zero” Law

3. Newton’s Laws of Motion

Describe how objects in the world move and react to forces.

- The Inertia Law: An object at rest, stays at rest

- Force = Mass * Acceleration (F = ma)

- The Law of Reciprocity: For every action there is an equal and opposite reaction

4. Complexity

A complex system exhibits emergent behavior due to the collective interaction of many individual agents according to simple rules.

Complex systems are sensitive to original conditions, influenced by feedback loops, and buffeted by random outside variables.
