1.   Modern accelerators tend to be rather large machines to produce the very high energy particles required to produce new particles.

2.   And particles produced in weak-force interactions, it turns out, are preferentially left-handed.

3.   In principle there are two ways to show that the weak force can produce right-handed particles at extremely high energies.

4.   Laboratory tests show that explosives tend to produce tiny particles of sticky residue that are very hard to remove.

5.   Radials are more likely to produce airborne particles than the older bias ply tires.

6.   Sanding produces particles that can lead to allergies and respiratory sicknesses.

7.   The protons collide with water molecules, producing particles called pions, which in turn slam into a copper target generating a spray of neutrinos and other particles.

8.   They produce organic particles with names like taurine and betaine that hold onto water and keep it from leaving.

9.   Yet scientists have yet to find any phenomenon nearby that could produce particles of such high energy.
