Amazing plants

Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος (lithos), meaning "stone," and ὄψ (ops), meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones.

Science, like life, feeds on its own decay. New facts burst old rules; then newly divined conceptions bind old and new together into a reconciling law. ~William James, The Will to Believe and Other Essays in Popular Philosophy, 1910

Mysterious!!!!

The Bagdad Battery

The Baghdad Battery, sometimes referred to as the Parthian Battery, is the common name for a number of artifacts created in Mesopotamia, during the dynasties of Parthian or Sassanid period (the early centuries AD), and probably discovered in 1936 in the village of Khuyut Rabbou'a, near Baghdad, Iraq. they may have been galvanic cells, perhaps used for electroplating gold onto silver objects. Though far from settled, this interpretation continues to be considered as at least a hypothetical possibility. If correct, the artifacts would predate Alessandro Volta's 1800 invention of the electrochemical cell by more than a millennium

Water: A priceless gift.....

“If gold has been prized because it is the most inert element, changeless and incorruptible, water is prized for the opposite reason -- its fluidity, mobility, changeability that make it a necessity and a metaphor for life itself. To value gold over water is to value economy over ecology, that which can be locked up over that which connects all things.

A lesson for LIFE

“The Seven Social Sins are:
 Wealth without work.
 Pleasure without conscience.
 Knowledge without character.
 Commerce without morality.
 Science without humanity.
 Worship without sacrifice.
 Politics without principle.

From a sermon given by Frederick Lewis Donaldson in Westminster Abbey, London, on March 20, 1925

“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
