Does this explain what generates gravity?

Author of Alice in Wonderland, Lewis Carroll (aka mathematician Charles Dodgson) did not believe that it was justified to use imaginary numbers in mathematics.

In the Mad Hatter's tea party it was always tea-time, no matter the time, because time had left the room. According to Dodgson, the whole world would eventually turn into a massive Mad Hatter’s tea party if imaginary numbers had their way.

I read it here: https://www.scienceabc.com/pure-sciences/what-is-imaginary-time.html

I bet he and Terrence McKenna hung out together in the outer realms, and had absolutely massive parties. Carroll chopping porcinis for afternoon tea and McKenna tinkering with the flux kaleidoscope.

Forget the Mad Hatter, we're all mad here! 😀

My own trick is to intensely observe and hence know the answers.

I happen to know that "The Hammers" is West Ham United F.C.!

Also that (my team...) Coventry City F.C.won the F.A. Cup Final in 1987.

I was there:

This is consequence of missing ontology, more exactly: missing distinction of object and concept: Our "physicists" are mostly "philosophers", and also only unsuitable;-)

Think of all the time and money I wasted on my university education! I could have gotten the real "truth" from a half wit ding dong on the internet that makes copious use of scare quotes.

 

[Fast Eddie D]

Sure. I could have been a legend in my own mind; quacking like a duck.

You're a card, Steve! 😊

At least we can explain how to generate artificial gravity! 😎

I am unashamedly a PHYSICIST!

What was I watching that kept me interested when all around were falling asleep?

AFAIK, it was Carl Sagan:

Made a lot of sense to me,

Merciful rockets, Steve, your hairdresser must have practised barberism!

'Well', Steve, it was nice to be reminded of that bit of history!

Eratosthenes measured the circumference of the Earth over 2 millenia ago, but some misguided souls stilll insist the World is flat! 😵

At noon on the summer solstice, the sun shone straight down the well at Syene (S), while the pole at Alexandria (A) cast a shadow.

If we take the angle subtended by the shadow of the pole as 7.2 degrees then the full 360 degrees corresponds to (800/7.2 x 360) or 40,000 km.

Omer Simpson can prove the Earth' s shape is a donought from Eratosthenes measurements

Now let's get this Clear!

Erastothenes was the Chief LIbrarian of Alexandria. A Library that included Euclid, Pythagoras and other Greats in Mathematics and Physics.

So who was the Guy who measured the Circumferance of the Earth? Clearly not Erastosthenes.

I detect a logical inconsistency here. 😎

Just sayin':

Clearly not, as it was Eratosthenes, not Erastosthenes who is credited with measuring the circumference of the Earth. 😉

What is this "logical inconsistency" that you detect? If you are implying that someone did it before him, that is not the case.

When the ancient Greek philosopher Pythagoras first suggested that the Earth was round in 500 BC, his claim was dismissed as unreasonable. Decades later, Greek philosopher Aristotle proved Pythagoras correct when he concluded that the Earth was spherical by observing celestial bodies from different locations across the planet. Ancient mathematicians and self-proclaimed astronomers also tried to prove Aristotle wrong, but eventually concurred that Earth was indeed spherical. About 2,000 years ago, long after the Earth was proved to be round, Eratosthenes of Cyrene, a Greek polymath, poet, astronomer, mathematician, librarian, and geographer, sought to establish the planet's circumference.

Simultaneous/synchronized measurements 800km apart?

How easy it is to replace the everyday images of people by fictitious images, and thus their everyday perception and understanding, understanding of the world, self-understanding, we experience at present, for example, also by war propaganda;-)

Please note that the circumference also pertains to a circle, not necessarily to a sphere, so I believe that everyone still has the right to believe in what they want regarding our beloved Mother Earth. 😉 🙂

Yes, synchronised by the Sun.

Both observations were made at noon on the summer solstice.
