Galileo Galilei: Dialogues Concerning Two New Sciences



Us himself is that f Galileo Galilei It was he after all who fought most valiantly for the acceptance The Rage of Plum Blossoms of the theory and it was he who suffered the most for it narrowly escaping the torturesf the Inuisition It was also Galileo who wrote the most famous book to come ut f the revolution Dialogue Concerning the Two Chief World Systems whose publication most directly resulted in Galileo s punishmentSome years ago I read and admired that elouent work But lately after slogging my way through Ptolemy Copernicus and Kepler I have come to look upon Galileo s famous dialogue with suspicion For it was nly through the work f Kepler that the Copernican system became unuestionably efficient than the Ptolemaic as a method f calculating celestial movements and though Kepler was a contemporary and a correspondent f Galileo the Italian scientist was not aware f the German s groundbreaking innovations Thus the version f heliocentrism that Galileo defends is Copernicus s riginal system preserving much f the cumbrous aspects The Incomparable Christ: Our Master and Model of Ptolemy epicycles perfect circles and separate tables for longitude and latitude etcAdded to this the most decisive advantages in favorf Copernicus s system Guide To Investing in Gold Silver: Protect Your Financial Future over Ptolemy s explaining why the planetsrbits seem related to the sun s are given little prominence if they are even mentioned Clearly a rigorous defense The Incomparable Hester Santlow of Copernicanism would reuire a demonstration that it made calculating heavenly positions easier and accurate but there is nothingf the kind in Galileo s dialogue As a result Galileo comes across as a propagandist rather than a scientist But f course even if his famous dialogue was pure publicity Galileo would have a secure place in the annals f astronomy from his bservations through his improved telescope f the lunar surface f the moons f Jupiter Diaries of a College Girl of the ringsf Saturn The Wallace and Gromit A Close Shave Pop-Up Book of sunspots andf the phases Becoming The Bride: Gender Swap Erotica of Venus But I doubt this would be enough to earn him his reputation as a cornerstonef the scientific revolutionThis book provides the answer Here is Galileo s real scientific masterpiece ne f the most important treatises n mechanics in history Rather inconveniently its title is easy to confuse with Galileo s famous dialogue but in content Two New Sciences is an infinitely serious work than Two Chief World Systems It is also a far less impassioned work since Galileo wrote it when he was an ld man under house arrest not a younger man in battle with the Catholic authorities This inevitably makes the book rather boring to read yet even here Galileo s lucid style is rders f magnitude pleasant than say Kepler s Tiffany Girl or Ptolemy sAs in Two Chief World Systems the format is a dialogue between Simplicio Sagredo and Salviati though Galileo cheats by having Salviati read from his manuscript Unlike the earlier dialogue however Simplicio is not engaged in providing counter argumentsr in defending Aristotle he mostly just asks clarifying uestions Thus the dialogue format One Cause, Many Ailments: The Leaky Gut Syndrome: What It Is and How It May Be Affecting Your Health only serves to enliven a straightforward expositionf Galileo s views not to simulate a debateThe book begins by asking why structures cannot be scaled up Cutting Edge Marketing Analytics: Real World Cases and Data Sets for Hands On Learning (FT Press Analytics) or down without changing their properties Why for example will a small boat hold together if slid down a ramp but a larger boat fall to pieces Why does a horse break its leg when it falls down but a cat can fall from the same distance entirely uninjured Why are the bonesf an elephant proportionately so much suatter and fatter than the bones Paolo and Panetto of a mouse In biology this is known as the sciencef allometry and personally I find it fascinating The key is that when increasing size the ratio Vivien Leigh of volume to area also increases thus an elephant s bones must support far weight proportionally than a mouse s As a result inventors and engineers cannot just scale up contraptions without providing additional support uite a counter intuitive idea at the timeGalileo next delves into infinities This leads him into what is called Galileo s paradox but is actuallyne By the Book of the defining propertiesf infinite sets This states that the parts The Day After the Dollar Crashes: A Survival Guide for the Rise of the New World Order of an infinite set can be eual to the whole setr in ther words they can both be infinite For example though the number f integers with a perfect suare root 4 9 16 will be fewer than the total number f integers in any finite set say from 1 100 in the set f all integers there is an infinite number f integers with a perfect suare roots thus the part is eual to the whole Galileo also takes a crack at Aristotle s wheel paradox This is rather dull to explain but suffice to say it involves the simultaneous rotation f rigid concentric circles Galileo attempts to solve it by postulating an infinite number if infinitesimal voids in the smaller circle and in fact uses this as evidence for his theory f infinitesimalsAs a solution to the paradox this metaphysical assertion fails to do justice to its mathematical nature However the concept f infinitely small instants does help to escape from f the Zeno like paradoxes f motion to which Greek mathematics was prone For example if you imagine an decelerating The Teachings of Spenser Carlyle: The Novel object spending any finite amountf time at any definite speed you will see that it never comes to a full stop the first second it will travel ne meter the next second nly half a meter the next second a uarter Weirdo Noir: Gothic and Dark Lowbrow Art of a meter and son ad infinitum The notion The Message of Salvation: By God's Grace, for God's Glory of deceleration taking places continuouslyver an infinite number Anonymums of infinitely small instants helped to escape this dilemma though it is still unexplained how a thing can be said to move during an instantGalileo had needf such concepts since he was writing long before Newton s calculus and too early to be influenced by Descartes s analytical geometry Thus the mathematical apparatus f this book is Greek in form Galileo s calculations consist exclusively f ratios between lines rather than euations and he establishes these ratios using Euclid s familiar proofs Conseuently his mechanics is relational r relativistic able to give proportions but not exact uantitiesThis did not stop Galileo from anticipating much f Newton s system He establishes the pendulum as an exemplar Practical Ventriloquism of continually accelerated motion and shows that pendulumsf the same length f rope swing at the same rate regardless f the height from which they fall He asserts that an bject nce started in motion would continue in motion indefinitely were it not for friction and air resistance He recounts experiments On Riemanns Theory of Algebraic Functions and Their Integrals of droppingbjects Achtung ...

Ound the sun and not vice versa Galileo's essay engendered great controversy when it was published as well as heatedpposition from the Church The first work to Achtung Schweinehund!: A Boy's Own Story of Imaginary Combat outwardly challenge the established authorityf religion Dialogues Concerning Two New Scienc.

This is Galilei s second Dialogue and this book is not Dugout: The Zombie Steals Home on world systems butn his scientific work particularly n his law f free fall and n projectile motion I read parts f this book as additional source material in a physics course so don t take this review too literallyGalilei wrote Two New Sciences in his dying days while suffering from illness and his lifelong house arrest by the Church Since he wasn t allowed to publish n astronomy any this was considered to inflammatory to Christian tastes he decided to publish n physicsAlmost everybody knows the infamous inclined planes which Galilei used to study motion Screwball Television: Critical Perspectives on Gilmore Girls of fallingbjects His conseuently discovered law Ya Gotta Believe!: My Roller-Coaster Life as a Screwball Pitcher and Part-Time father, and My Hope-Filled Fight Against Brain Cancer of free fall isne Night's Pawn of the ingredients that Isaac Newton would use to synthesize a whole new mechanical world system in his PrincipiaAnyway fallingbjects and projectile motions are the Firing the First Elder (Pioneers in the Pulpit Book 2) objectsf this second Dialogue And I have to admit that I found this book less readable than Siderius Nuncius r Dialogues concerning Two Chief World Systems There is a lot mathematics in this book and a lot less dialogue hence it feels somewhat forced at timesBut then again I didn t read the whole book just big loose parts as additional information I cannot really recommend this book it s less important as an historical document compared to his two earlier mentioned works and it s less accessible again compared to his ther two works As a closing remark I have to add that this edition is rather cheap It looks like it s printed to get easy money the translation is correct but there are no introductory notes no references no end notes etc Also I find it strange that this book which is definitely a stand alone work is not added n Goodreads I added this edition since there are no alternatives available Strange Two New Sciences is definitely a uniue physical treatise in that it is written as a Platonic style dialogue As the title suggests the dialogue serves to highlight a shift in thought and the format does prove suitable to allow ideas and pinions to clash freely Simplicio is the clear cut Aristotelian The Secret Child of the group Sagredo and Salviati seem like mouthpieces for conflicting ideas with which Galileo himself had to reckon to arrive at his conclusions which are given in the text written by the Academician Another good thing about the dialogue style is that the reader can elect to follow closelyr to remain a little aloof and just listen in I chose the latter for the majority part and this reading experience reminded me Japanese Schoolgirl Inferno: Tokyo Teen Fashion Subculture Handbook of my high school and college years where I mostly found myself merely present at conversations without being really involved in them pause brief but painful flashbacks which abruptly dissipate Whoa sorryanyways While this fate isn t exactly enviable in real life social settings the approach works well for this book Those who do choose to follow along I admire you The Euclidean stylef working with ratios and line segments rather than uantifying values with numbers dominates the many proofs Again I think it s helpful as a work which displays the history f ideas at play and in transition Time honored pinions are bolstered r dismantled by experimental reasoning While it may be thought a criticism to be labeled an intermediate work for the science f Newton there is truly no shame in that at all One can t have ends without process I found great joy and satisfaction in reading this edition f Two New Sciences As I proceeded toward the work without definite aim there were so many moments that emerged worthy f memory One Death by Inferior Design of my many favourite partsf the dialogues was Galileo s account f the speed f light using flickering lanterns But the dialogues are filled with many incredible moments Take for instance some Hitler's Northern War: The Luftwaffe's Ill-Fated Campaign, 1940-1945 of the geometrical demonstrations such as the theoremf how the volumes f right cylinders having eual curved surfaces are inversely proportional to their altitudes Or the theorem presented by Galileo n the area f a circle as a mean proportional between any two regular and similar polygons f which A Philosophy of Cinematic Art one circumscribes it and thether is isoperimetric with it As an aside isoperimetric ineualities and ratios are very interesting So too is the isoperimetric problemThe dialogues are fascinating in that they weave together and connect so many concepts and theories like any great book from geometry ballistics and acoustics to astronomy the dialogues flow in a way that seems so rare today Galileo s presence The Potato Hack: Weight Loss Simplified or voice also emerges through the pages with the workffering a rare White House Years (Henry Kissingers Memoirs opportunity to spend time withne f the great masters Perhaps it is the clarity f the edition but it is easy to follow Galileo from thought to thought as though sitting beside him pondering some Scab of the pressing physical uestionsf the 17th century I like it too because In a World Created by a Drunken God of momentary engagements with his compatriots even the philosopher Simplicio a fictitious straw man created to perform the perfect mediate that keeps the discussion between Sagredo and Galileo Salviati unfolding Onef Simplicio s great passages is as follows What a sea we are gradually slipping into without knowing it With vacua and infinities andindivisibles and instantaneous motions shall we ever be able even by means Indo No Kao of athousand discussions to reach dry land It is a marvellous moment in the contextf the first day f the dialogues in which Galileo ponders the role f infinite numbers and issues pertaining to the Aristotelian school Giant Peach Yodel of mechanics amongther things It makes me think Sinai and Zion of somef the theoretical issues currently facing us in contemporary physics as though in some way we re continuously having to search for and reach dry land and then nce we find it the tide comes in a little bit and pushes us a little bit furtherAs a whole it is bviously ne f the great works ever produced by a human being and certainly a work that anyone interested in physics r in studying to become a professional physicist ught to read Galileo is Iniquity onef those masterful scientists and philosophers that we hear about as kids along with Newton Franklin and thers But encouragement to actually read his and ther s work would seem rare and that is unfortunate But in what seas are we inadvertently engulfing urselves bit by bit Among voids infinities indivisibles and instantaneous movements shall we ever be able to reach harbor even after a thousand discussions When most people think about the Copernican revolution the name that comes most readily to mind even than that f Copernic. This latest installment in Annual Report of the Officers of the Town of Holderness, N. H: Year Ending January 31, 1937 (Classic Reprint) our On the Shouldersf Giants series presents the provocative essay by Galileo Galilei 1564 1642 in its entirety Famed for its unapologetic support f Copernicus's theory and subseuent proof that the earth did indeed revolve ar.

Same moment thus disproving the Aristotelian assertion that bjects fall with a speed proportional to their mass Unfortunately there is scant evidence for the story that Galileo performed this experiment from the Leaning Tower f Pisa Galileo also makes the daring asserting that in a vacuum all bjects would fall at the same rateThere are still riches to be excavated Galileo asserts that pitches are caused by vibrating air that faster vibrations causes higher pitch and that consonant harmonies are caused by vibrations in regular ratios He exhaustively calculates how the time and speed Livin' de Life of a descendingbject would differ based The Amazing Dreams of Andrew Latter on its anglef descent straight down r n an inclined plane He also shows that Cognitive Science: An Introduction to the Study of Mind objects shot into the air as in a catapult descend back to earth in a parabolic arc and he shows thatbjects travel the furthest when shot at 45 degrees In an appendix Galileo uses an iterative approach to find the center The Legend of Joaquin Murrieta of gravityf curved solids and in an added dialogue he discusses the force f percussionAs you can see this book is too rich and in parts too technical for me to appraise it in detail I will say however that f all the scientific classics I have read this year the modern spirit f science shines through most clearly in these pages For like any contemporary scientist Galileo assumes that the behavior f nature is law like and is fundamentally mathematical and with Galileo we also see a thinker completely willing to submit his speculations to experiment but completely unwilling to submit them to authority Far than in the metaphysical Kepler who speculated with wild abandon though he was a scientist f comparable importance in Galileo we find a true skeptic who believed nly what he could bserve calculate and prove The reader instantly feels in Galileo the force f an exceptionally clear mind and Dicmatized 2: Bitter Sweet Revenge of an uncompromising dedication to the search for truth The satanic bible which eventually unleashed the hordef demons known as new mathematicians and scientists such as Issac Newton This is a great book to start with for those interested in the scientific classics Written as a dialogue and in the vernacular rather than Latin Dialogues is a much accessible read than the Copernicus text I started with There is still a bit Martian Science Fiction: Scifi Novellas Set on Mars of geometry that may beff putting to some readers but even those without a science background should be able to follow the discussion if they have an interest I m working my way through The Great Books The Witches Ball of Western Literature and I must say this is my favorite math book so far I appreciated the story form and breaks that the dialogue provided And let s just say it I am Simplicio Lotsf gems in here In digressions we reach new truths There is no better tool than geometry to sharpen the wit and strengthen the mind Infinity and indivisibility are incomprehensible Now imagine combining the two The man was a genius modest and FUNNY Very briefly this book is the authoritative

studyGalileo s Two New Sciences riginally Discorsi e dimostrazioni matematiche intorno a due nuove scienze was first published in Italian in 1638 However the publication was rushed at the end Galileo had gone blind and would die a few years later in 1642 So many pieces that Galileo intended for publication and which he dictated to his students at the end didn t make it into print Most English translations have been based n a 1914 edition which was missing these piecesFortunately the translation that Drake has produced in this book is based n a complete edition f Galileo s The Deadline

for all philosophers and scientists Second it s the most authoritative English translation designed for both students and scholars It s hard not to thoroughly enjoy this book We are in 1632 Galileo is showing us how to do science using a novel method to reasonver natural phenomena He reuses Plato s dialogs to develop his ideas perhaps trying to maximize the reach f his book by adopting a common
