Most powerful microscope in the world

British scientists have presented the most powerful optical microscope in the world, that can display detail of 50-billionth of a meter, and experts believe it will have greatest application in biology and medicine, especially the use of observation cells and study of viruses and bacteria.
The new technology uses short waves that are emitted close to the observed object, they break through the glass lenses and provide a view of the traditional microscope.
In this way, scientists will be able to see details with their own eyes that have so far been possible only through atomic force microscopy, and scanning electron microscopy.

The Earth is not flat – but the Universe is

Based on Einstein’s Theory of General Relativity, there are three possible shapes that the Universe may take: open, closed, and flat. Once again, measurements by WMAP on the CMBR have revealed a monumental confirmation – the Universe is flat.

Combining this geometry and the idea of an invisible entity known as dark energy coincides with the widely accepted ultimate fate of our universe, which as stated earlier, is a Big Freeze.

Roman Coliseum facts

At the time of its construction, the Colosseum had the capacity of seating around 50,000 spectators.

Initially, the amphitheater was used for holding gladiatorial contests and public spectacles, such as mock sea battles, animal hunts, executions, re-enactments of famous battles and dramas based on Classical mythology.

Roman Coliseum remained in use for nearly 500 years. The last recorded games were held in it in the 6th century.

It was in the medieval era that the amphitheater ceased to be used for entertainment purposes. Thereafter, it was used for housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.

The games played in the Colosseum are believed to have taken the lives of about 500,000 people and over a million wild animals.

Though ruined by earthquakes and stone-robbers, the amphitheater serves as an iconic symbol of Imperial Rome.

Roman Coliseum is one of the most popular tourist attractions of Rome and still holds close connections with the Roman Catholic Church.

On every Good Friday, the Pope leads a torchlit "Way of the Cross" procession to the amphitheatre.

The amphitheater has been depicted on the Italian version of the five-cent euro coin.

The Colosseum is an entirely free-standing structure, 189 m (615 ft) long, 156 m (510 ft) wide and with a base area of 6 acres (24,000 m2).

The height of the outer wall of the amphitheater is 48 m (157 ft), with the perimeter originally measuring 545 m (1,788 ft).

The central arena of Roman Coliseum is oval in shape, being 287 ft long and 180 ft wide. It stands surrounded by a 15 ft high wall, which has tiers of seating above it.

It has been estimated that the outer wall of the amphitheater required over 100,000 cubic meters (131,000 cu yd) of travertine stone.

The stones used in the outer wall of the Colosseum were set without mortar. In fact, they were held together by 300 tons of iron clamps.

The arena of the amphitheater is estimated to have the dimensions of 83 m by 48 m (272 ft by 157 ft).

The surviving facade of Roman Coliseum's outer wall is made up of three stories of superimposed arcades, framed by half-columns of the Doric, Ionic, and Corinthian orders.

The arcades of the amphitheater have been surmounted by a podium on which stands a tall attic, decorated with Corinthian pilasters.

There were special boxes in the Colosseum, at north and south ends, for the Emperor and the Vestal Virgins, providing the best views of the arena.
