For all time, scientists have deciphered less than 1% of the data the Large Hadron Collider
Large Hadron Collider - is one of the most amazing inventions of mankind, which is responsible for the discovery of numerous subatomic particles, including the elusive Higgs boson. And in recent years, new data hint at new discoveries beyond the Standard Model. And this is very surprising, because, according to scientists, we can decipher less than 1% of the data from the accelerator. Therefore, the opening of the LHC can be called a "great luck". Or are all the same no?
The physicists used 26, 7 km of the LHC to accelerate particles to near light speed and then confronted them to see if they can find something new. These particles collide with incredible speed, which leads to the insane amount of data. On its Web site CERN notes that one billion collisions per second generates 1 petabyte of data. And this is a problem, because to maintain (not to mention the analysis) is the amount of data is extremely difficult.
"If we want to keep all 30 million events per second, we would need about 2,000 petabytes of storage for a typical 12-hour work cycle. In the year of the LHC running 150 days, which means we get almost 400,000 petabytes (400 exabytes) in a year. This amount of information is physically impossible to keep. "- he said in an interview ScienceAlert CERN physicist Andreas Hecker. "It is worth mentioning about the data processing. CPU power is simply not enough. We can not process data as fast as they come. "
Thus, it was necessary to make a decision about which fall into the vault, and which are not. Out of every 30 million collisions recorded in all 1200. It's only 0, 004% of the total amount of data, and the remaining 99, 996% lost forever. That sounds pretty scary when you consider that we might have missed.
"But do not panic. Most of the known processes are relatively rare. For example, the appearance Higgs very rare process. At maximum intensity LHC collisions, we produce about 1 Higgs boson in the second. Other interesting physical processes are less rare, but we are using "triggers" - quick online algorithms based on special hardware and software to select the most interesting events of the less interesting. "
In this case, in order not to miss something interesting, the scientists propose to build new detectors for the Large Hadron Collider. Then the question of storage and decrypt them without the fear of losing something important will disappear by itself.
