Useful Beliefs

do you believe in Father Christmas, do you believe in a brave New Year?

do you believe in the ten commandments, is your life filled with fear?

To believe is to accept that something exists, or that something is true, when there is no evidence or proof to back up that belief.  Millions of children around the world believe in Father Christmas, Santa Claus, Kris Kringle, Saint Nicholas…..  He will remain in the hearts of children forever, and the children have proof, he brings them toys and other gifts every Christmas.  This belief is useful too, for doesn’t he have a list of who’s been naughty and who’s been nice, checking it twice before he leaves toys and presents for the nice children, and a lump of coal for the naughty boys and girls.  A perfect cautionary tale for parents to blackmail their kids into being nice near Christmas.

Some beliefs are neither useful nor true ~ like a Flat Earth.  Those who believe the Earth is flat are either deranged, or willfully stupid, or as thick as two short planks.  There is plenty of evidence to prove the planet Earth is more or less a sphere, as are all the other planets visible through a telescope.  Also believing in a flat Earth is not useful, since long-distance navigation is based on the great circle theory, which is navigating a ship or an aircraft using spherical trigonometry.  Ergo believers in a flat Earth should never ever get on an aircraft or go on a cruise.

One does not have to believe everything one hears.  ~  Cicero

Another belief that is neither useful or true is Alien Visitation.  There are plenty of spurious reasons given to prove that alien visitation happens all the time, and I don’t believe any of them.  There is also one crushing piece of evidence to disprove the very idea that creatures / people from the stars regularly visit the Earth ~ nothing can travel faster than the speed of light.  The nearest known exoplanet is 4.25 light years away, so allowing for basic physics that means a round-trip of about 12 years, even if our starship can get near the speed of light.  Just never going to happen.

One false belief that is useful is in Pythagoras’ theorem; the square on the hypotenuse is equal to the sum of the squares on the other two sides.  Or more practically just remember 3,4,5.  This is mostly true, but some believe it is always true.  Try navigating from England to New York using Pythagoras and the Gods only know where you will land.  Sometimes even the dearest held, and most provable belief is only mostly true.

Believing in God, any God, is maybe the most commonly held belief of them all, along with whichever prophet fits the religion of your choice.  This belief is useful to many, especially the clergy of every religion, but there is no proof whatsoever, and that’s the whole point.  Religion is all about Faith not Belief ~ and if you start to look into Faith you get into a circular argument.  Anyway I think religion isn’t based on faith, it’s about the fear of eternal damnation

Some say that real belief needs no proof.  And that faith is trust without reservation.  All I know is I trust scientific and engineering methodologies more than I trust priests and demagogues. And I believed in Love.

the Earth is positively not flat

 

 

The Flat Earth Conspiracy

Those who are able to see beyond shadows will never be understood.

April Fools Day

The Earth from Space.  (that’s Atlanta GA in the centre)

A bunch of conspiracy theorists who persist in believing that the Earth is flat are planning a trip to Antarctica to see ‘the end of the world’.  I think they really mean the “edge of the world”, but you wouldn’t expect anyone who believes in a flat Earth to have a good grasp of semantics.

Good luck on that trip.  If the Earth really was as flat as a pancake they would never get there because all navigation by sea and air relies entirely on the fact that the Earth is an oblate spheroid ~ that is not at all flat.

Mind you, as the next meeting of the Flat Earth International Conference will be held in Dallas, Texas, the spiritual home of conspiracy theories.  I’m guessing that their meetings are filled with febrile debates about nothing that is within shouting distance of reality.  You know what?  I would have expected the Flat Earth Bunch to be headquartered in California, where they really do know how to party with psychoactive substances.

There is no evidence whatsoever for a flat Earth, other than the evidence of our own eyes when our feet are planted firmly on the ground.  In that case, when we look around us, the Earth does seem flat ~ other than hills and mountains, and valleys, and gorges…..  The Pythagorean theorem, one of the oldest mathematical proofs in Euclidian Geometry, is predicated on the Earth being flat.  However, Pythagoras falls apart when great distances across the Earth are involved, in which case we need to use spherical trigonometry.  (Which only works for big balls.)

As far back as Columbus in 1492 AD, navigators knew the Earth was a spheroid, although Columbus got the circumference badly wrong.  The Norse Vikings knew the Earth was a sphere when they travelled to America in about 1,000 AD.  The Ancient Greeks were thinking about a spherical Earth in the 6th Century BC, and before that the Phoenicians navigated great distances based on the idea that the Earth was a sphere.

The Moon is a sphere too

Only in the Bible is the idea of a flat Earth much popularised, and as we all know, everything in the bible can be treated as the Gospel Truth.  However, if you are interested in exploring the flat Earth conundrum, the Flat Earth Society has a cool website  https://www.tfes.org/

Some say that NASA’s sole reason for existence is to propagandize the public and promote this false ball-Earth heliocentric worldview.  And that there was never a moon landing, it was all shot in a studio in Culver City.  All I know is that some gullible fools are eager to believe the stupidest pseudo-scientific dross.  And the moon really is made of green cheese.

some say that real women have absolutely no sense of direction, and that no woman will ever admit that they’re wrong,  some of that is mostly true
