Formed on the Vindhyan and Deccan trap rocks of the south, it is clayey, dark and able to hold water through a dry spell, which is why the gram, wheat, oilseed and pulse crops of Jhansi, Jalaun, Hamirpur and Banda depend on it.

Bhur is the raised sandy soil of the upper doab in districts such as Meerut, Bulandshahr and Aligarh, blown into low ridges by the wind, poor in moisture and organic matter, and fit for bajra, barley and, where irrigation reaches, for sugarcane.

Usar, also called reh, is the saline and alkaline soil of districts such as Raebareli, Unnao, Hardoi, Kanpur and Aligarh, where sodium salts gather on the surface; gypsum, which is calcium sulphate, replaces the sodium on the clay particles with calcium, the sodium is then washed away by drainage, and…

Bhangar is the old alluvium of the higher ground away from the present river channels; it is darker, more clayey and dotted with the lime concretions called kankar, and it is not renewed by fresh silt.

Western disturbances travel from the Mediterranean across Iran and Pakistan and give the plains a few spells of light rain in December, January and February, exactly when wheat, gram, barley and mustard are standing in the field, so farmers call this shower the golden drops.

It is a hot, dry and dusty wind that blows from the west over the northern plains in the afternoons of May and early June, pushing the temperature past forty-five degrees Celsius in Agra, Jhansi and Banda and causing heat stroke, and it stops only when the monsoon arrives.

The monsoon current enters from the Bay of Bengal in the south-east and loses moisture as it travels up the plain, so the eastern districts and the Terai of Gorakhpur, Bahraich and Lakhimpur Kheri are the wettest, while Mathura, Agra and the Bundelkhand districts of Jhansi, Jalaun and Banda are…

This branch strikes the Ganga delta, is turned west by the Himalaya and moves up the Ganga plain, so it reaches eastern Uttar Pradesh about the middle of June and then travels on to the west, which is why the east of the state gets both earlier and heavier rain.

Placed in a cavern under about 1,300 metres of rock at Pottipuram in the Bodi West Hills, it is designed to catch atmospheric neutrinos and measure how they change from one flavour to another, the phenomenon of neutrino oscillation; the magnetic field lets it tell a neutrino from an antineutrino.

The site was chosen for its flat, seismically quiet ground, the Union Cabinet approved the project in principle in 2016 and in full in April 2023, and it is being executed by the Department of Atomic Energy and the Department of Science and Technology with IPR, RRCAT Indore and IUCAA…

Gravitational waves are ripples in space-time thrown out by violent events such as the merger of two black holes, and they follow from the general theory of relativity that Einstein published in 1915, with the prediction of the waves set out in 1916.

Fusion is the joining of two light nuclei into a heavier one, with a neutron or other products released and a large amount of energy appearing because the mass of the product is slightly less than the mass of the reactants; in ITER the reaction fuses deuterium and tritium into…

A hydrogen bomb, also called a thermonuclear bomb, uses a fission explosion only as a trigger; the main energy comes from the fusion of the heavy hydrogen isotopes deuterium and tritium into helium at temperatures of millions of degrees, which is why the process is described as thermonuclear or thermal…

This institute of the Department of Atomic Energy is the national centre for plasma and fusion research, it houses the domestic agency ITER-India that supplies India share of the machine, and it operates India own tokamaks Aditya and SST-1, the Steady State Superconducting Tokamak.

ITER is coming up at Saint-Paul-les-Durance in the Cadarache area of southern France, and its seven partners are the European Union, China, India, Japan, Russia, South Korea and the United States; the name is the Latin word for the way.

These are the two general purpose detectors on the LHC ring, and in July 2012 both independently reported a new particle of about 125 giga-electronvolts that matched the Higgs boson, the particle linked to the field that gives mass to other particles; the Nobel Prize in Physics of 2013 went…

The European Organization for Nuclear Research, founded in 1954, has its campus at Meyrin on the outskirts of Geneva in Switzerland, and because its tunnels run under the border, parts of the laboratory lie in France as well.

The Large Hadron Collider occupies a circular tunnel about 27 kilometres around, lying roughly 100 metres below the ground on the Swiss-French border near Geneva, and it is the largest and most powerful particle accelerator ever built; the tunnel was originally dug for an earlier CERN machine, the Large Electron-Positron…

Keoladeo Ghana National Park at Bharatpur, once the duck shooting reserve of the Bharatpur rulers, was listed in 1981 and is also a World Heritage Site famous for its winter migratory birds; the Sambhar salt lake was listed in 1990 and attracts flamingos.

Nakki lake lies at Mount Abu, the only hill station of Rajasthan, in Sirohi district, and the local story that it was dug out with nails gives it its name; Toad Rock stands on its edge and the ashes of Mahatma Gandhi were immersed in it.
