Ever wondered why people say they can smell rain before it rains? They are not pulling your leg - there is real science behind it. It is all because of petrichor, made up from the Greek words "petra", meaning stone, and '"ichor", which refers to the golden fluid that flows in the veins of the gods in their mythology. It basically means the the "smell of rain" with the phrase coined by Australian scientists Joy Bear and Richard Thomas in 1964. Jeff Weber, a meteorologist with the University Corporation for Atmospheric Research Unidata Program Center told the Mirror: "Petrichor is caused by oils derived from plants, primarily leaves, that accumulate over dry periods. These oils settle into soils or onto pavement over time and are released into the atmosphere by being disturbed by rainfall." According to the Met Office, the reason people claim to smell rain because it comes is because "when a higher humidity is experienced as a precursor to rain, the pores of rocks and soil become trapped with moisture forcing some of the oils to be released into the air".

This is when raindrops landing on soil "trap tiny air bubbles on the surface which then shoot upward" and "burst out of the drop throwing aerosols of scent into the air where they are then distributed by the wind". The smell is produced by a soil bacteria which releases a chemical called geosmin, which provides an "earthy", musky or fresh aroma. Before it rains, a person might be able to smell the scent of ozone, or O3, which is a naturally present gas in the atmosphere which gets its name from the Greek word 'ozein', or smell. It sometimes indicate that a storm is on the way because pockets of gas are pushed down to ground level by winds. This means that those who are sensitive to the smells will likely be able to pick them up. So now you know. Have your say in our news democracy.

The release of Christopher Nolan’s Oppenheimer has generated a flurry of interest in the man behind the atomic bomb, Julius Robert Oppenheimer. The film tells the story of the physicist and his role in the Manhattan Project, which was the the codename given to the development of the A-bomb. Oppenheimer, who referred to himself as “death, destroyer of worlds”, was the figurehead of the project, which involved splitting the atom and the devastation wrought by two atomic bombs being dropped on Japan in 1945. Sign up to our free Indy100 weekly newsletter The first bomb was dropped on the city of Hiroshima on 6 August 1945. It killed tens of thousands of people. It was nicknamed Little Boy. Oppenheimer Atomic bomb How it Works | First Nuclear Bomb www.youtube.com A second bomb fell days later on the city of Nagasaki, this time nicknamed Fat Man. Historians believe more than 200,000 people died as a result of the events, with millions more severely affected. Now, YouTube channel AiTelly has produced a video of what exactly happens inside such a weapon to create such a wave of destruction. The animation shows that when the bomb falls, it activates a switch that triggers a trio of navy gun primers, which in turn ignite a charge inside the weapon. Four silk powder bags containing two pounds of cordite, an explosive powder, push the the uranium projectile forward at 300 metres-per-second. The uranium collides with more uranium at the front of the bomb, combining them with four polonium initiators, which create nuclear fission. This is the act of splitting the atom, and it is what creates the huge expulsion of energy – the explosion. Have your say in our news democracy.

A meteor exploded over the Atlantic Ocean at a force comparable to the atomic bomb dropped on Hiroshima during the Second World War. While this may sound like a scary prospect, there is nothing to worry about as this asteroid did not actually hit the Earth. The debris burned up at a height of around 31 kilometres above the Atlantic Ocean off the coast of Brazil, experts say. Data from NASA showed that the meteor appeared to release the equivalent energy of around 12,000 tonnes of TNT - that's approximately 12 kilotons of explosive power. Sign up to our free Indy100 weekly newsletter Similarly, the Hiroshima Bomb detonated with an approximate energy of 15 kilotons – that is, 15 thousand tonnes of TNT equivalent. This force caused devastation in the Japanese city and killed at least 80,000 people instantly, with tens of thousands dying later due to radiation exposure. Although 12 kilotonnes does sound like a lot, there have also been other explosions that have had a higher number than this. One example is the 450 kilotons of explosive energy (0.45 megatons) released as a result of the Chelyabinsk meteor back in 2013 - 26 to 33 times as much energy as the Hiroshima Bomb. The house-sized asteroid exploded 14 miles above the ground and generated a shock wave that blew out windows over 200 square miles and damaged some buildings. Over 1,600 people were injured in the blast, mostly due to broken glass, according to NASA.
