CERN produces massive amounts of data each second.
~ 25 Petabyte / year
~ 68 Terabyte / day

What would a visual of the number of books it would take to have the same amount of data as CERN in one day?

Chemistry: Activity #3

Chemistry: Activity #3
Step 1: Students use the tool in Minecraft Element Constructor to study the atomic structure in a creative way.
Step 2: Students investigate Standard Model of particle physics by CERN, LHC and Particle Adventure. It starts with an accurate description of the subatomic structure of the matter showing an atomic model with electron and quarks. Then students create model of atomic structure by Blender
Step 3: Lectures about particle physics, detectors, accelerations and computing at CERN. Skype -a- scientist.
Step 4: Knowing the computing power to model an atom, discuss the computing bandwidth required to model one second of collisions and the number of particles involved and about computing.
Used ISOLDE Yield Database shown in Fig 2, find produced isotopes 5 elements independent on the target. Find production details: target density, ion source on Target and Separators page. This also greatly reinforces the abilities of students of chemistry to think through the immense quantity of data.

Description of activities: Activity #4
Network speed transfer
16
To analyze 3 aspects of computing and compare to the resources that students has at home or school
Data Center Comparison: Activity #4
Network speed transfer
17
Students will compare some of their devices´s transmission speed with the transfer rate reached at CERN.
(cell phones,WiFi at home, etc)
Students will study some storage units they use, such as pendrives, hard disks, and compare them with the tape storage system used in the Datacenter. (deal with units, TB...)
Comparison between the processors and cores running in the GRID for moving the data to storage, with the processing power of a desktop computer or an iPhone.
