    Just an FYI: Easter on the Gregorian Calendar contains a double astronomical reference: The first Sunday after the first Full Moon after the Vernal (Spring) Equinox. Eclipses, which occur only during new or full moons, can therefore never happen on Easter Sunday.

    No. Contrary to widespread suspicions, Stephen Hawking and I were never buddies in childhood.

    An Unapologetically Geeky Fact: The eccentricity of the ellipse that is the White House Oval Office is: e = 0.62, with the desk chair positioned at one focus & the couches near the other. (FYI: eccentricity of a Circle: e = 0.00; of a Parabola: e = 1.00)

    His passing has left an intellectual vacuum in his wake. But it's not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP 1942-2018.

    In five-billion years, as the Sun begins to die, its outer layers of glowing plasma will expand stupendously, engulfing the orbits of Mercury, then Venus, as the charred ember that was once the oasis of life called Earth vaporizes into the vacuum of space. Have a nice day!
