The second of Hercules’ twelve labors was to slay the Hydra. In reality, Hera was behind the twelve labors and hoped that Hercules would be killed while attempting to complete them. Because Hercules had killed his wife Megara and his children in a fit of lunacy, he was set twelve labors by Eurystheus, King of Tiryns, as a punishment. The Hydra has become a famous figure because of its connection to the adventures of Hercules. Taken this way, it’s clear that the Hydra was a monster of monsters, with many powers that made killing it a major feat. Poisonous Blood: The Hydra’s blood was considered poisonous and could kill anyone who came into contact with it.Several Heads: There are different references to the number of heads that the Hydra had, but in most versions, she was said to have nine heads, of which the central head was immortal, and could only be killed by a special sword. Furthermore, if one of her head was severed from her body, two more would regenerate in its place, making it nearly impossible to kill the monster.Acid: Being a hybrid, with multifaceted origins, Hydra’s internal organs produced acid, which she could spit, bringing a gruesome end to the person before her.Anyone who breathed the same air as that of the monster would die instantly. Poisonous Breath: It is said that the sea monster’s breath was perhaps the most dangerous tool at her disposal.The Lernaean Hydra had many powers, which was why she was so difficult to kill. Its destruction became one of the twelve labors of Hercules. It lived in the marshes around the Lake of Lerna, near Argos and terrorized the people and livestock of the area. As the story goes, the Hydra was raised by Hera, one of Zeus’ many wives, to be a vicious monster with the goal of killing Hercules (a.k.a. The Hydra was the offspring of Typhon (said to be the descendent of lions) and Echidna (herself a hybrid creature being half-human and half serpent). It was also the guardian of the entrance to the Underworld. It had poisonous breath and blood and was able to regenerate two heads for every head that was chopped off. The Lernaean Hydra, or the Hydra of Lerna, was a gigantic serpentine sea monster with multiple heads, that existed in both Roman and Greek Mythology. Here’s a look at the story and end of the Hydra of Lerna. From here, the beams inside the LHC are made to collide at four locations around the accelerator ring, corresponding to the positions of four particle detectors – ATLAS, CMS, ALICE and LHCb.The Lernaean Hydra is one of the most intriguing yet terrifying monsters of Greek mythology, best known for its connection with Hercules and his 12 labors. The particles are so tiny that the task of making them collide is akin to firing two needles 10 kilometres apart with such precision that they meet halfway.Īll the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. Just prior to collision, another type of magnet is used to "squeeze" the particles closer together to increase the chances of collisions. These include 1232 dipole magnets, 15 metres in length, which bend the beams, and 392 quadrupole magnets, each 5–7 metres long, which focus the beams. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator.

This requires chilling the magnets to ‑271.3☌ – a temperature colder than outer space. The electromagnets are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. They are guided around the accelerator ring by a strong magnetic field maintained by superconducting electromagnets. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator.
