...last project, which lasted 13 years, led to the recent discovery of the top quark, the last of 12 fundamental building blocks of matter yet to be discovered...
Franklin and a group of about a hundred other physicists working at Harvard and the Fermilab worked to prove the existence of the last undiscovered quark, the "top" quark, by collecting two years' worth of data from collisions between protons and antiprotons...
...contributions to the quark project was to build 70 tons worth of detector to measure the behavior of particles resulting from quark disintegrations...
Scientists at the Fermi National Accelerator Laboratory, near Chicago, have finally found the physical evidence of a subatomic particle that has eluded physicists for more than a decade. It's the top quark, the heaviest of the six quarks that serve as the basic building blocks of matter and the last to be discovered; there were hints of a sighting last spring, but it took nearly a year for physicists to be sure...
Scientists have confirmed the existence of the so-called "top quark," a basic building block of nature dating from the time of the "big bang" that helped begin the formation of galaxies between 8 billion and 25 billion years ago. Physicists at Energy Department's Fermi National Laboratory near Chicago announced they verified evidence of the missing subatomic particle, without which scientists' theories of time and matter would simply fall apart. "This provides a sense of relief," says TIME senior science writer Michael Lemonick, who notes that the top quark completes a set of six oddly-named particles that account...
