SUMMARY
Scientists have achieved cooling of atoms to just one ten-billionth of a degree above absolute zero using laser cooling techniques. This method involves tuning laser frequencies to ensure that only atoms moving toward the light can absorb photons, thereby slowing them down. The foundational work in this area was pioneered by Steven Chu and William Phillips, both of whom received Nobel Prizes in Physics for their contributions. The discussion highlights the practical application of physics principles in achieving extreme low temperatures.
