How does a rainbow form?
Rainbows form when sunlight passes through water droplets in the atmosphere, causing the light to refract, reflect, and disperse into the colors of the spectrum: Refraction: When light passes from air into a denser medium, like a raindrop, it changes direction. This is called refraction. Reflection:Read more
Rainbows form when sunlight passes through water droplets in the atmosphere, causing the light to refract, reflect, and disperse into the colors of the spectrum:
See lessRefraction: When light passes from air into a denser medium, like a raindrop, it changes direction. This is called refraction.
Reflection: The light reflects off the back of the raindrop.
Dispersion: The light disperses into the seven colors of the spectrum.
For a rainbow to appear, the sun, raindrops, and the observer must be in the right positions:
The sun must be behind the viewer.
The sun must be low in the sky, at an angle of less than 42° above the horizon.
Rain, fog, or some other source of water droplets must be in front of the viewer.
Rainbows appear semi-circular over level ground at sunrise or sunset. When viewed from the air, rainbows form a complete circle.
What is the structure of an atom?

The structure of an atom is made up of three particles: protons, neutrons, and electrons:
See lessProtons: Positively charged particles located in the nucleus
Neutrons: Uncharged particles located in the nucleus
Electrons: Negatively charged particles that orbit the nucleus in shells
The nucleus is a dense, positively charged part of the atom that contains more than 99.9% of its mass, even though it’s usually less than one ten-thousandth the size of the atom.
The arrangement and number of these particles in an atom determine its properties. For example, a hydrogen atom has one proton, one electron, and no neutrons.
To draw an atom structure, you can:
Draw a small circle to represent the nucleus
Write the number of protons and neutrons in the nucleus
Calculate the number of electrons in the atom
Draw the atom’s shells
Fill the shells with the correct number of electrons for the element
The number of protons and neutrons in an atom can be found on the periodic table. The top number is the mass number, which is the sum of the number of protons and neutrons. The bottom number is the atomic number, which is the number of protons.

pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being.Ocean pollution has many causes, including:
See lessNonpoint source pollution
This is pollution that comes from many small sources, like vehicles, septic tanks, farms, and livestock ranches. It’s often caused by runoff, which is when rain or snow carries pollutants from the ground to the ocean.
Point source pollution
This is pollution that comes from a single source, like an oil spill or chemical spill.
Plastics
Plastic bags are one of the most deadly types of plastic in the ocean because they can be mistaken for food by marine life. They can take up to 20 years to decompose.
Offshore drilling
The oil and gas industry’s operations can lead to spills, which can cause irreversible damage to marine ecosystems.
Ocean acidification
This occurs when the pH of the ocean lowers, which can have harmful effects on marine organisms.
Air pollution
Some water pollution starts as air pollution, which settles into waterways and oceans.
Other pollutants
Other pollutants include:
Chemical runoff
Crude oil
Sewage
Fertilizers
Discarded fishing nets
Noise from shipping and drilling

The meaning of Crop rotation is the practice of growing different crops in a specific order on the same land over multiple seasons. The goal of crop rotation is to maintain the soil’s productivity by preventing it from being used for only one set of nutrients.
See lessCrop rotation can have many benefits, including:
Soil health: Improves soil structure, fertility, and organic matter
Pest and disease control: Breaks the life cycle of pests and diseases, reducing the need for chemical pesticides
Weed growth: Reduces weed growth
Crop yield: Increases crop yield
Labor efficiency: Distributes labor more evenly throughout the seasons
A simple rotation might involve two or three crops, while a complex rotation might include a dozen or more. For example, a farmer might plant beans after harvesting corn because corn uses a lot of nitrogen and beans return nitrogen to the soil.

Pratibha Devisingh Patil (born 19 December 1934), also known as Pratibha Patil Shekhawat,is an Indian politician and lawyer who served as the 12th president of India from 2007 to 2012. She was the first woman to become the president of India. A member of the Indian National Congress, she also served as the Governor of Rajasthan from 2004 to 2007, and was a member of the Lok Sabha from 1991 to 1996.Patil was born in a Marathi family on 19 December 1934 in the village of Nadgaon in Jalgaon, Maharashtra. She was the daughter of Narayan Rao Patil.She was educated initially at R. R. Vidyalaya town and subsequently was awarded a master’s degree in Political Science and Economics by Mooljee Jetha College, Jalgaon (then under Poona University), and then a Bachelor of Law degree by Government Law College, Bombay, affiliated to the University of Bombay (now University of Mumbai). Patil then began to practice law at the Jalgaon District Court, while also taking interest in social issues such as improving the conditions faced by Indian women.
Patil married Devisingh Ramsingh Shekhawat on 7 July 1965. The couple has a daughter, Jyoti Rathore and a son, Raosaheb Shekhawat, who is also a politician.In 1962, at the age of 27, she was elected to the Maharashtra Legislative Assembly for the Jalgaon constituency.[8] After that she won in the Muktainagar (formerly Edlabad) constituency on four consecutive occasions between 1967 and 1985, before becoming a Member of Parliament in the Rajya Sabha between 1985 and 1990. In the 1991 elections for the 10th Lok Sabha, she was elected as a Member of Parliament representing the Amravati constituency. A period of retirement from politics followed later in the decade.
Patil had held various Cabinet portfolios during her period in the Maharashtra Legislative Assembly and held official positions in both the Rajya Sabha and Lok Sabha. In addition, she had been the president of the Maharashtra Pradesh Congress Committee for a few years. Also, she held office as Director of the National Federation of Urban Co-operative Banks and Credit Societies and as a Member of the Governing Council of the National Co-operative Union of India.
On 8 November 2004 she was appointed the 17th Governor of Rajasthan,the first woman to hold that office.Patil was announced as the United Progressive Alliance (UPA) candidate on 14 June 2007. She emerged as a compromise candidate after the left-wing parties of the alliance would not agree to the nomination of former Home Minister Shivraj Patil or Karan Singh.Patil had been loyal to the INC and the Nehru–Gandhi family for decades and this was considered to be a significant factor in her selection by INC leader Sonia Gandhi, although Patil said that she had no intention of being a “rubber-stamp president”.
In the same month that she was selected as a member of the UPA, Patil was accused of shielding her brother, G. N. Patil, in the 2005 Vishram Patil murder case. Vishram Patil had narrowly defeated G. N. Patil in an election to be the President of the District Congress Committee of Jalgaon and in September of that year had been murdered. Vishram Patil’s widow eventually accused G. N. Patil of involvement in the crime and claimed that Pratibha Patil had influenced the criminal investigation and that the issue needed to be examined before presidential immunity became active. Her accusations were rejected by the courts in 2009but in 2015 G. N. Patil was charged. No reference to the alleged involvement of Pratibha Patil was made at this time.
Due to the presidential role being largely a figurehead position, the selection of the candidate is often arranged by consensus among the various political parties and the candidate runs unopposed.Contrary to the normal pattern of events, Patil faced a challenge in the election. The BBC described the situation as “the latest casualty of the country’s increasingly partisan politics and [it] highlights what is widely seen as an acute crisis of leadership”. It “degenerated into unseemly mudslinging between the ruling party and the opposition”.Her challenger was Bhairon Singh Shekhawat, the incumbent vice-president and a Bharatiya Janata Party (BJP) veteran. Shekhawat stood as an independent candidate and was supported by the National Democratic Alliance (NDA), a group led by the BJP,although the Shiv Sena party, which was a part of NDA, supported her because of her Marathi origin.

Varying myths of Ganga’s birth is found in Hindu scriptures. According to the Bhagavata Purana, Vishnu, in his incarnation as Vamana, extended his left foot to the end of the universe, and pierced a hole in its covering with the nail of his big toe. Through the hole, the pure water of the causal ocean entered this universe as the Ganges river. Having washed the lotus feet of the lord, which are covered with reddish saffron, the water of the Ganga acquired a very beautiful pink colour. Because the Ganges directly touches the lotus feet of Vishnu (Narayana) before descending within this universe, it is known as Bhagavat-Padi or Vishnupadi, which means emanating from the feet of Bhagavan (God). It finally settles in Brahmaloka or Brahmapura, the abode of the Brahma, before descending to the planet earth at the request of Bhagiratha, and held safely by Shiva on his head, to prevent the destruction of Bhumi Devi (the earth goddess). Then, Ganga was released from Shiva’s hair to meet the needs of the country.[3]
The Ramayana narrates a different version of the myth. Ganga is described as the eldest child of Himavat, son of Brahma and the king of the Himalayas, and his Menavati, the daughter of Meru. Her younger sister is Parvati, who latter marries Shiva. When Ganga attained youth, the devas took her to Svarga, where she took a form of a river and flowed.The Ganges River is considered the holiest river in Hinduism and is central to Hindu spirituality and cultural heritage:
See lessSacred water
The Ganges is worshipped as the goddess Ganga and is considered the most sacred body of water in Hinduism. Hindus believe that bathing in the Ganges, touching it, or naming it cleanses sins.
Salvation
Hindus believe that immersing the ashes of their dead in the Ganges, a custom known as asthi visarjan, gives the deceased direct passage to heaven and freedom from the cycle of birth and death.
Pilgrimage sites
Many places along the banks of the Ganges are considered sacred and are sites of Hindu pilgrimage, including Haridwar, Prayagraj (Allahabad), and Varanasi (Benares).
Festivals
Festivals such as Ganga Dussehra and Ganga Jayanti are celebrated at sacred sites along the Ganges.
Rituals
Many rituals are performed on the banks of the Ganges, including floating clay cradle boats, releasing aquatic life, and performing evening aartis.
Water in homes
Many Hindu families keep a vial of water from the Ganges in their homes. It is also customary to give a sip of Ganga water to someone who is dying. The Ganges, also known as the Ganga River, originates from the Bhagirathi River, which flows from Gaumukh at the base of the Gangotri Glacier in the western Himalayas of Uttarakhand, India. Gaumukh is about 13 miles (21 km) southeast of Gangotri.
The Bhagirathi and Alaknanda rivers meet at Devprayag, where the river is named the Ganga. The Ganga flows through India and Bangladesh and eventually empties into the Bay of Bengal.
The Ganga is considered the longest holy river by Hindus and is worshipped as the goddess Ganga.

Sufism is the esoteric path within Islam, where the goal is to purify oneself and achieve mystical union with the Supreme (named Allah in this tradition). The practitioners of Sufism are called Sufis, and they follow a variety of spiritual practices, many of which were influenced by the tradition of Yoga in India. In this post, I’ll explore the several types of Sufi meditation techniques.
Unlike many of the other meditation techniques, Sufi meditation is spiritual by nature. There is no “secular version” of these techniques, as the idea of God is part of their DNA. The core of all their practices is to remember God, fill the heart with God, and unite oneself with Him. So if you are atheist or agnostic, you probably won’t find these meaningful.There are several symbolic benefits to it as well.
The journey of the Sufi is the journey of the lover returning to the arms of the Beloved, a journey of love in which we “die” as egos so we can be one with Him. It’s the way of the heart. All of the practices are aimed at letting go of one’s ego, which is considered the biggest obstacle to realization.
The roots of Sufism date back to around 1400 years ago, but they became near-extinct in the 20th century. There are different orders of Sufis, each emphasizing different exercises. In this article, I have drawn techniques from different schools.
Sufism is not a monastic path. The Sufi wayfarer lives in the inner world of the heart as well as functioning responsibly in society.
