In Hall C, in an experiment that began on January 21 and concluded on March 3, researchers took a closer look at matter's blueprints with a study of the spin-structure functions of the proton and the neutron, collectively known as nucleons.
Building a bridge over land or water requires careful engineering. There is the weight of passing cars and trucks to consider. Will high winds or turbulent weather threaten the structure? How deep should the concrete foundations be poured? How best to affix the steel supports? What is the ideal mix of materials for strength, durability and corrosion resistance? Nature has long ago figured out how best to arrange atoms that comprise ordinary matter. The nuclei inside those atoms are systems of quarks, the particles thought by many to be matter's basic building blocks. Humans are only now beginning to unravel the engineering secrets of quarks, how they are precisely arranged and how their interactions determine the properties of the atomic nucleus.
