1928

Dirac equation

• Paul Dirac made Schrödinger’s equation
• consistent with Einstein’s theory of relativity,
• relating not only to
• the Planck constant
• but also to
• the speed of light.

Dirac sea

• Dirac’s hole theory predicts
• that so-called empty space
• is a sea of electrons.
• Electrons are negatively charged
• and repel each other,
• so this sea is never at rest.
• Bubbles in this restless sea
• act like positive particles,
• later called positrons.

Jellium

• Space is made, theoretically, of jellium,
• something like blackberry jam with seeds, I suspect.
• It seems more likely to exist
• in those heavy D batteries when fully charged,
• but without the purple color, as shown when they leak.
• Jellium is a uniform distribution
• of positive charges in a semiconductor
• acting like a metal, or an artificial brain,
• whether fully charged or leaking with age,
• whose neurons are dealing with negativity.
