The Bayana Horde has given historians a new perspective on imperial Gupta rulers. The horde has confirmed the prosperity of ancient India, and the kind of workmanship which allowed such artistic coins to be developed.

Ancient Needles

The origin of the sewing needle goes back to the Palaeolithic age. Since then to now, 30,000 years later, hardly any change can be discerned.

A Zeptosecond

Scientists have measured the time taken for a light particle (photon) to cross a hydrogen molecule. It is 247 Zeptoseconds or 247 x 10−21 sec.

Ancient Indian Mathematics

Mahaviracharya was a brilliant mathematician from South India. His treatise ‘Ganitasarasangraha’ , written around 870 CE, is one of the earliest text devoted entirely to mathematics.

Red colour comes from bugs

The red colour (Carmine) comes from the Cochineal insect that thrives in the warm climate on cactus. This colour is then added to foodstuff, cosmetics, pharma drugs, alcoholic drinks etc. to give the distinct red colour.

Lost city of Tanis

The lost city of Tanis was made famous by the movie Indiana Jones – Raiders of the Lost Ark. The treasures found at this site rival those found in King Tut’s burial chamber.

Birds perceive colour better than humans

Birds have enhanced vision acuity both by day as well as by night. This is necessary both to acquire a meal as well as avoid becoming a meal. Further, it is an added advantage while searching a for a suitable mate.

The Antikythera Mechanism

Two thousand years ago, a Greek mechanic set out to build a machine that would model the workings of the known Universe. The result was a complex clockwork mechanism that displayed the motions of the Sun, Moon and planets on precisely marked dials. By turning a handle, the creator could watch his tiny celestial bodies trace their undulating paths through the sky.

Mpemba effect

Under some conditions, hot water freezes faster than cold water. Scientists have long known that it can happen but have not been able to explain for sure why. In fact, it was first noted as early as the 4th century B.C. by Aristotle.

Ticks have a long life

Male African Ticks can live upto 4 years without food while females lived upto 8 years. With regular diet they could live upto 27 years.

Animals’ pupils come in different shapes and sizes

Animals with vertically elongated pupils are very likely to be ambush predators which hide until they strike their prey from relatively close distance. They also tend to have eyes on the front of their heads. Horizontally elongated pupils are nearly always found in grazing animals, which have eyes on the sides of their head. They are also very likely to be prey animals such as sheep and goats.

Human head transplant—possible?

The world’s first human head transplant has been carried out on a corpse in China in 2020 by Dr Sergio Canavero. He later said that he is now ready to perform the surgery on a living person. The operation was carried out by a team led by Dr. Xiaoping Ren.

Underwater Camouflage by Animals

Underwater camouflage is the set of methods that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey.

Ultra-Black Fish

Scientists have discovered at least 16 species of ultra-black fish, each equipped with specialised skin that allows them to evade detection while hunting or hiding in the dark. Absorbing 99.95 percent of all photons, this blacker-than-black exterior creates a cloak of invisibility against the ocean’s dim backdrop. Even under a harsh spotlight, these creatures appear as mere silhouettes.

Ultra-Ever Dry

Ultra-Ever Dry is a superhydrophobic (water) and oleophobic (hydrocarbons) coating that will completely repel almost any liquid. Ultra-Ever Dry uses proprietary nanotechnology to coat an object and create a barrier of air on its surface. This barrier repels water, oil and other liquids unlike any coating seen before.

Speed of light can be dropped to zero

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms.

Flying Dragons

The Flying Dragon is a bizarre creature. Also known as a Flying Lizard or Gliding Lizard, this reptile uses modified ribs to glide through the air.
