1925

Bose-Einstein condensate

• Satyendra Nath Bose
• realized that two photons with equal energy
• are indistinguishable
• which means that the probability
• of heads and tails is the same
• as tails and heads
• and thereby
• he invented a new statistics
• to describe black-body radiation
• which led Albert Einstein
• to realize that some particles
• did not behave like particles
• and thereby
• predicted they could
• condense into
• a new form of matter
• in which the particles
• share a quantum state.

Bose-Fermi universe

• We have bosons,
• named after Satyendra Nath Bose,
• that can share the same quantum state at the same time,
• such as photons,
• and fermions,
• named after Enrico Fermi,
• that cannot share a quantum state at the same time,
• such as electrons,
• make up a universe
• of elementary and composite particles
• and considerable charged spaces between them.

States of matter

• Solid, liquid, gas,
• and other weird states
• teach us to
• always say “maybe.”
• Get serious,
• to have fun
• for a certain
• wacky effect.
• Helium may
• crawl up walls,
• ceramics may
• superconduct,
• particles may interact
• when light-years apart,
• and even a fool
• may sometimes be right.
