Johannes Kepler ï 9 REVIEW

REVIEW å Ioh Keppleri Mathematici Olim Imperatorii Somnium seu Opus Posthumum de Astronomia Lvnari Johannes Kepler ï 9 REVIEW FREE READ ↠ E-book, or Kindle E-pub ï Johannes Kepler Somnium Latin for The Dream is a fantasy written between 1620 and 1630 by Johannes Kepler in which a student of Tycho Brahe is transported to the Moon by occult forces It presents a detailed imaginative description of how the earth might look when viewed from the moon and is considered the first serious scientific treatise on lunar astro.

REVIEW å Ioh Keppleri Mathematici Olim Imperatorii Somnium seu Opus Posthumum de Astronomia Lvnari Johannes Kepler ï 9 REVIEW FREE READ ↠ E-book, or Kindle E-pub ï Johannes Kepler Nomy Carl Sagan and Isaac Asimov have referred to it as the first work of science fictionSomnium began as a student dissertation in which Kepler defended the Copernican doctrine of the motion of the Earth suggesting that an observer on the Moon would find the planet's movements as clearly visible as the Moon's activity is to the Earth's. Friends do you have a moment to talk about 17th century astronomer and mathematician Johannes Kepler He has been wronged by history and I aim to be the fan girl to set the record straightIf you learned about early modern science the way I did growing up you primarily learned about Galileo Galilei and his telescope aided astronomical discoveries that overturned the geocentric model of the solar system and brought us into a enlightened age Then you skipped straight on to Sir Issac Newton to talk about gravity But neither Galileo s discoveries nor Newton s theory of universal gravitation were possible without Johannes Kepler Some facts Kepler described the terrain of the moon using a combination of naked eye observations and pure a priori reasoning before Galileo observed the moon s surface through his telescope confirming many of Kepler s conclusions Kepler s ideas about the moon were wildly radical for the time The official view of the universe supported by the Catholic and Lutheran churches described heavenly bodies as perfect spheres embedded in other perfect crystalline spheres with Earth at the center This view of the universe was a priori ism run amok and leveraged towards maintaining faith but regardless describing the moon as a world with imperfections like mountains and valleys and perhaps oceans and rivers was next to heresy How is Earth uniue in God s creation if the universe is full of innumerable worlds Yet this is what Kepler proposed before Galileo s confirmation Kepler developed a conception of gravity 80 years before Newton describing it as a permeating force similar to magnetism He was also the first person to use inertia in its modern sense This was no small feat During Kepler s time Aristotelian type theories prevailed enforced by the Catholic and Lutheran churches which saw Aristotelianism as compatible with biblical literalism These theories viewed gravity as the result of matter s propensity to seek its pre ordained place in the world It was highly teleological and relied on a fundamentally different conception of space matter and force To break with this view was an act of unspeakable intellectual creativity And Newton himself rightly credited Kepler for this genius While Galileo usually gets the praise for overturning the geocentric model of the solar system it was Kepler who did the heavy lifting by calculating the orbit of Mars using Tycho Brahe s painstaking observations Kepler s entire life s work including Somnium probably did to establish the heliocentric model of the solar system than any number of contributions made by any other person since Copernicus Why Because he had the proverbial receipts His observations and calculations were undeniable But than pure empiricism or pure reason his writing was able to help people imagine other possibilities for the universeAnd here begins my review of SomniumThis book is the most prescient work of fiction I have ever read It s wildly creative and while fundamentally wrong on some counts the moon for instance is decidedly not inhabited what s amazing is all the ways in which it s rightFor instance solar radiation In Kepler s enumerations of the dangers of a voyage to the moon he lists solar radiation a concept that just didn t exist in his time He reasoned two things 1 light is always associated with heat and 2 as you gain elevation the atmosphere thins He put these two ideas together to realize that if you left Earth s atmosphere you d be directly exposed to unmitigated solar radiation which would at least burn you if not kill you outright What s even fascinating is that he lists cold as another danger This is deeply counterintuitive if you believe that burns from a source of heat are a danger Nevertheless he reasoned that Earth s atmosphere was acting as a blanket retaining ambient heat so if you loose the conductive capacity of the atmosphere you lose ambient heatOther insights He believed that Earth s atmosphere was being held in place by gravity He believed that gravity was a force that diminished with distance and was related to the mass of an object So as you move away from a body with mass you leave its atmosphere He conseuently prescribed a breathing aid for interplanetary travelers He believed that the tides of Earth s oceans were caused by the gravitational pull of the moon He was the first person to discover this and he was ridiculed Others argued that if the moon was causing the tides through attraction why did a high tide occur when the moon was on the opposite side of the planet Kepler responded that an eual and opposite reaction could be expected that once the moon passed the ocean would rebound back from it s unnaturally high position to form a bulge on the back side of the planet due to the inertia of the water itself he was of course proved right Kepler also believed that the moon s gravity would need to be taken into account when plotting the course of an interplanetary journey the very first person to describe interplanetary trajectory calculations He believed that to escape Earth s gravity you d need exceptional thrust which he described as a cannon a la Jules Verne 200 years later He noted that the forces caused by such acceleration would wreck havoc on human anatomy so he prescribed special force dampening harnesses and sedatives to control heart rate He recognized that there would be a hypothetical neutral point in the gravitational pull between the Earth and the moon so things would float in space He recognized you d need breaking thrusters to counter the moon s gravity on a descent to the surface He understood that gravity would be weaker on the moon and that that would translate into a thinner atmosphere He was wrong about the moon having an atmosphere but so was pretty much everyone before the 20th century Meanwhile he used his understanding of gravity to shape the type of life he thought might exist on the moon saying that such life needed to be able to extract oxygen from water to avoid relying on the thin atmosphere and that life would grow very large due to the weak gravity Moon creatures would also live in caves and canals to avoid exposure to solar radiation and temperature extremes driven by the moon s exceptionally long days and nights He was wrong in believing the moon had oceans but what s interesting is that he realized that Earth s gravitational pull on the moon would result in the earth side face being covered in water explaining the apparently large oceans on the earth side face He also envisioned what the heavens would look like from the moon describing how much of the sky would appear to go retrograde as the moon completed its back side orbit around the earth and how navigation on the moon s surface could be aided by reference to Earth s fixed position in the sky The moon s inhabitants meanwhile would have a very different conception of time given their days last a full month in Earth termsI truly don t understand how Kepler reasoned all this out He wasn t building from anything except maybe Plutarch and a smattering of other ancient Greeks and Romans It would be like writing about time travel today from nothing than a handful of philosophy and math classes and having the theoretical physics of it be conceptually correct even though it contradicts our current standard modelYet he did And in describing all of this Kepler gave people a way of imagining what life would look like from the moon It helped them see the moon as a place in and of itself and it helped people understand that our perspective on everything heavens included is contingent on our human perspective from Earth How differently might things look if we were to free ourselves from those constraintsThis is the power of science fiction Speculation Shifts in perspective and though them new possibilities arising from obscurity It s powerful Necessary even As Thomas Kuhn described in The Structure of Scientific Revolutions and as Max Jammer has described in his groundbreaking works all of scientific pursuit is human endeavor bounded by human phenomenology and human psychology How then can we break out of old paradigms to explore new possibilities Though creativity and imagination Though people uncowed unconstrained by social norms and in Kepler s and Galileo s case by direct threats to life and limb And literature is a vehicle that can be used to explore controversial ideas in safe perhaps subversive waysHowever writing Somnium was not safe for Kepler The work was written as an allegory in order to make it palatable but unfortunately Kepler s imagined journey to the moon was taken with his mother who he described as a herbalist capable of speaking with the spirits who inhabit the wild northern regions of Iceland Accordingly word of mouth accounts of the then unpublished story were used as evidence in charging Kepler s mother with witchcraft and she was imprisoned Kepler spent an entire year painstakingly constructing a legal defense to secure his mother s release which relied on finding scientific explanations for all the various charges against her eg cows not giving milk a pain in a child s arm etc etc Though his mother was released she ultimately died as a result from her imprisonmentThe price of a dream that would ultimately launch humanity on its first steps to the stars was the life of an innocent woman It was a price that rocked Kepler to the coreIn reading Kepler s various works he was never boastful He was careful and particularly after the death of his mother he was always aware of the political and physical dangers of the ideas he proposed While Galileo writes in grandiose terms Kepler often comes across world weary I believe he was weary of the world that killed his mother And yet in spite of everything what s most moving about Kepler s writing is the pure joy in the beauty of the universe and all its mysteries Joy and love and boundless possibility Kepler fuses fantasy and science fiction in this work He writes that witches old women accustomed to riding broomsticks over the wild barrens in the depth of night are the perfect hardy travelers for a voyage to the moon He writes that spirits know the way to the moon indeed the moon is where spirits live The way to the moon is through tunnels of shadow a very fae turn of phrase though he literally means that you have to travel in the cone of shadow made by the moon or earth blocking the sun s powerful solar radiation So you either have to spiral outward from earth always saying night side while traveling upwards from earth s surface until you reach the plane on which the moon travels at which point if you ve plotted your course correctly the moon will come to meet you once you ve gained sufficient elevation OR you have to do the entire journey in the course of an eclipse Incidentally this is why eclipses are bad luck they are opening the shadow tunnels between the earth and the moon allowing spirits to invade our worldIt s perfect Just perfect Scarlett Fever planet's movements as clearly visible as the Moon's activity is to the Earth's.
