  • NASA spacecraft Juno has collected new data on its mission to Jupiter revealing some of the swirling inner mysteries of the giant gas-planet.The surface of Jupiter, the fifth planet from the sun and the largest in the solar system, consists of alternating bright and dark bands of gas and winds flowing in opposite directions at massive speed.Previously there have been extensive studies of the helium-and-hydrogen planet's surface, but now gravity measurements collected by Juno indicate that this turbulent outer layer extends to a depth of 1,900 miles (3,000 kilometers).
  • "Galileo viewed the stripes on Jupiter more than 400 years ago," Yohai Kaspi, Juno co-investigator from the Weizmann Institute of Science, Rehovot, Israel, and lead author of a Nature paper on Jupiter's deep weather layer, was quoted as saying on NASA's website."Until now, we only had a superficial understanding of them and have been able to relate these stripes to cloud features along Jupiter's jets. Now, following the Juno gravity measurements, we know how deep the jets extend and what their structure is beneath the visible clouds," said Kaspi, who likened the advancement to going from a "2-D picture to a 3-D version in high definition."
  • "Juno's discovery has implications for other worlds in our solar system and beyond."

  • he Renaissance – that cultural, political, scientific and intellectual explosion in Europe between the 14th and 17th centuries – represents perhaps the most profoundly important period in human development since the fall of Ancient Rome. 
  • From its origins in 14th-century Florence, the Renaissance spread across Europe –
  • It coincided with a boom in exploration, trade, marriage and diplomatic excursions... and even war.
  • ...11 more annotations...
  • Italy in the 14th century was fertile ground for a cultural revolution. The Black Death had wiped out millions of people in Europe – by some estimates killing as many as one in three between 1346 and 1353. 
  • By the simplest laws of economics, it meant that those who survived were left with proportionally greater wealth:
  • Advances in chemistry led to the rise of gunpowder, while a new model of mathematics stimulated new financial trading systems and made it easier than ever to navigate across the world. 
  • Renaissance art did not limit itself to simply looking pretty, however. Behind it was a new intellectual discipline: perspective was developed, light and shadow were studied, and the human anatomy was pored over – all in pursuit of a new realism and a desire to capture the beauty of the world as it really was. 
  • If the Renaissance was about rediscovering the intellectual ambition of the Classical civilisations, it was also about pushing the boundaries of what we know – and what we could achieve. 
  • Even as the artists were creating a bold new realism, scientists were engaged in a revolution of their own. Copernicus and Galileo had developed an unprecedented understanding of our planet’s place in the cosmos, proving that the Earth revolved around the Sun. 
  • Families such as the Medici of Florence looked to the Ancient Roman and Greek civilisations for inspiration – and so did those artists who relied on their patronage. 
  • olumbus discovered America, Ferdinand Magellan led an expedition to circumnavigate the globe. 
  • Even as our world shrank in size and significance when placed in the context of our new understanding of the universe, so it grew in physical terms, as new continents were found, new lands colonised, new cultures discovered whose own beliefs and understandings were added to the great intellectual firestorm raging across Europe. 
  • Never before (or since) had there been such a coming together of art, science and philosophy
  • The seeds of the modern world were sown and grown in the Renaissance. From circumnavigating the world to the discovery of the solar system, from the beauty of Michelangelo’s David to the perfection of Leonardo’s Mona Lisa, from the genius of Shakespeare to the daring of Luther and Erasmus, and via breathtaking advances in science and mathematics, man achieved new heights

  • Gov. Ron DeSantis just gave a welcome boost to the classical-education movement
  • This move will likely be portrayed, wrongly, as partisan and conservative. But the greatest works of civilization have always been about spurring—not preventing—radical change
  • They teach us about the revolutionary ideas of the past and help us better understand the present. The richest ideas of what it means to be human are those that have stood the test of time.
  • ...6 more annotations...
  • Many of the seminal works of literature, history, philosophy, science and theology were revolutionary in their respective ages
  • Like revolutionary ideas today, the ideas of yesterday were provocative and, in many cases, much more consequential
  • Revolutionary figures of the past give us insight into the present and allow for reflection on the consequences of their choices
  • That’s one of the virtues of the classics: They are a means of considering what is true without invoking the blind partisanship that encourages thoughtless action
  • There is nothing we need more today than the cultivation of reason and understanding.
  • Education based on values, logic and discipline isn’t Republican—it’s timeless

  • The Renaissance was a fervent period of European cultural, artistic, political and economic “rebirth” following the Middle Ages.
  • Some of the greatest thinkers, authors, statesmen, scientists and artists in human history thrived during this era, while global exploration opened up new lands and cultures to European commerce. T
  • Also known as the “Dark Ages,” the era is often branded as a time of war, ignorance, famine and pandemics such as the Black Death.
  • ...17 more annotations...
  • Some historians, however, believe that such grim depictions of the Middle Ages were greatly exaggerated,
  • Among its many principles, humanism promoted the idea that man was the center of his own universe, and people should embrace human achievements in education, classical arts, literature and science.
  • In 1450, the invention of the Gutenberg printing press allowed for improved communication throughout Europe and for ideas to spread more quickly.
  • Great Italian writers, artists, politicians and others declared that they were participating in an intellectual and artistic revolution that would be much different from what they experienced during the Dark Ages.
  • Although other European countries experienced their Renaissance later than Italy, the impacts were still revolutionary.
  • Leonardo da Vinci (1452–1519): Italian painter, architect, inventor, and “Renaissance man” responsible for painting “The Mona Lisa” and “The Last Supper.
  • Galieo (1564-1642): Italian astronomer, physicist and engineer whose pioneering work with telescopes enabled him to describes the moons of Jupiter and rings of Saturn. Placed under house arrest for his views of a heliocentric universe.
  • Donatello (1386–1466): Italian sculptor celebrated for lifelike sculptures like “David,” commissioned by the Medici family.
  • Raphael (1483–1520): Italian painter who learned from da Vinci and Michelangelo. Best known for his paintings of the Madonna and “The School of Athens.”
  • Michelangelo (1483–1520): Italian sculptor, painter, and architect who carved “David” and painted The Sistine Chapel in Rome.
  • Art, architecture and science were closely linked during the Renaissance.
  • For instance, artists like da Vinci incorporated scientific principles, such as anatomy into their work, so they could recreate the human body with extraordinary precision.
  • Renaissance art was characterized by realism and naturalism. Artists strived to depict people and objects in a true-to-life way.
  • Some of the most famous artistic works that were produced during the Renaissance include:The Mona Lisa (Da Vinci)The Last Supper (Da Vinci)Statue of David (Michelangelo)The Birth of Venus (Botticelli)The Creation of Adam (Michelangelo)
  • Also, changing trade routes led to a period of economic decline and limited the amount of money that wealthy contributors could spend on the arts.
  • By the early 17th century, the Renaissance movement had died out, giving way to the Age of Enlightenment.
  • While many scholars view the Renaissance as a unique and exciting time in European history, others argue that the period wasn’t much different from the Middle Ages and that both eras overlapped more than traditional accounts suggest.
