743 - MOSSY

Undeterred by the huge budgets and massive equipment used by other scientists, OScar was doing his own sub-atomic particle research in his garage. He was investigating different types of boson, fermion and hadron. One piece of equipment created Higgs bosons for brief periods of time. Some other apparatus isolated some of the gluons before they too vanished. He was convinced that he was on the trail of the elusive graviton that others were desparate to prove existed. The rest of his house suffered terrible neglect because Oscar was so engrossed. The gutter above the garage had become so mossy that during the next storm it gave way and crashed through the garage roof. The effects of the mythical graviton were plain to see! This was a nasty setback for Oscar because of all the mess covering his precious equipment.

(And, no, I also don't understand what Oscar was up to! But I can look up articles in Wikipedia!)

Bosons form one of the two fundamental classes of subatomic particle, the other being fermions. All subatomic particles must be one or the other. A composite particle (hadron) may fall into either class depending on its composition
