Timeline of Scientists of Scientific Revolution
The scientific revolution was the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed views of society and nature. The scientific revolution began in Europe towards the end of the Renaissance period and continued through the late 18th century, influencing the intellectual social movement known as the Enlightenment.
Timeline of a Scientific Revolution
- 1600 – Galileo Galilei discovers the principle of inertia, building the stage for a rational view of motion.
- 1600 – William Gilbert finds that Earth has magnetic poles and acts like a huge magnet.
- 1600 – Galileo Galilei discovers that projectiles move with a parabolic trajectory.
- 1608 – Hans Lippershey invents the refracting telescope, which Galileo Galilei soon puts to use.
- 1609 – Galileo Galilei observes moons of Jupiter, disproving church dogma that all movement in the universe is centered on Earth.
- 1609 – Johannes Kepler publishes his first two laws of planetary motion showing that planets move in elliptical orbits around the sun.
- 1610 – John Napier publishes tables of logarithms, showing how they can be used to accelerate calculations.
- 1619 – Kepler publishes his third law of planetary motion relating the time taken for a planet to orbit the sun with its distance from the sun.
- 1621 – Willebrord Snell discovers the laws of light refraction.
- 1628 – Kepler publishes his planetary tables, the calculations for which would have taken years without Napier’s logarithms.
- 1629 – Nicolaus Cabeus finds there are two types of electric charge and notes both attractive and repulsive forces acting.
- 1632 – William Oughtred invents the slide rule. With the combined power of logarithms and slide rules, calculation speeds explode.
- 1632 – Galileo Galilei finds that the laws of motion are the same in all inertial reference frames.
- 1637 – Rene Descartes invents the Cartesian coordinate system – i.e. the x-y axis for graphs, allowing changes in quantities with time to be plotted.
- 1645 – Blaise Pascal invents the adding machine.
- 1652 – Thomas Bartholin discovers the human lymphatic system.
- 1662 – Robert Boyle publishes his law of pressure and volume in gases.
- 1654 – Blaise Pascal and Pierre de Fermat invent the mathematics of probability and statistics.

- c1660 – Otto von Guerkicke builds a rotating sphere from which sparks fly. Static electricity can now be generated. He demonstrates electrostatic repulsion.
- 1660 – Robert Hooke discovers that the extension of a spring or elastic material is directly proportional to the applied force.
- 1661 – Robert Boyle writes The Skeptical Chymist, with his manifesto for the science of chemistry, explaining the roles of elements and compounds, and telling scientists they must carefully observe, record and report scientific data.
- 1633 – James Gregory publishes his design for the world’s first reflecting telescope.
- 1664 – Robert Hooke uses a microscope to observe the cellular basis of life.

- 1666 – Isaac Newton discovers that light is made up of all of the colors of the rainbow, which are refracted by different amounts in a glass prism.
- 1667 – Isaac Newton builds the world’s first reflecting telescope.
- 1668 – John Wallis discovers the principle of conservation of momentum – one of the foundations of modern physics.
- 1669 – Hennig Brand becomes the first identifiable person to have discovered and isolated a new chemical element – phosphorus.
- 1674 – Antony van Leeuwenhoek discovers microorganisms.
- 1675 – Robert Boyle shows that electric repulsion and attraction act in a vacuum.
- 1676 – Ole Christensen Roemer measures the speed of light for the first time.
- 1676 – Christiann Huygens finds light can be refracted and diffracted and should be considered to be a wave-like phenomenon.
- 1684 – Gottfried Leibniz publishes his calculus, which he discovered independently of Isaac Newton. He has been working on calculus for the past decade.
- 1687 – Isaac Newton publishes one of the most important books in scientific revolution ever: Philosophiae Naturalis Principia Mathematica, revolutionizing physics and our understanding of gravity and motion.
This was a momentous century in which science moved from a state of knowledge that was in many ways little more advanced than third century BC Greece to a much more advanced, sophisticated position, paving the way for the industrial scientific revolution in the 1700s, and many more famous scientists.
Probably the greatest advantages that Renaissance scientists had over their ancient Greek predecessors were:
- The invention of the movable type printing press in 1450 by Johannes Gutenberg
- Leonardo Fibonacci brought the Hindu-Arabic number system to Europe in 1202 AD.

The treatment options normally employed to deal with depression are –
Medicines
The newest and most popular anti-depressants are called selective serotonin reuptake inhibitors (SSRIs). Fluoxetine, sertraline, escitalopram, paroxetine, and citalopram are some of the most commonly prescribed SSRIs for depression.
Therapy
Yes, counselling sessions are a huge help, if the right kind of therapy is used, and combined with medicines, depending upon the type of depression and receptivity of the person. Two main types of psychotherapies —
Cognitive-behavioural therapy (CBT) – helps people with depression restructure negative thought patterns.
Interpersonal therapy (IPT) – helps people understand and work through troubled relationships that may be causing their depression or making it worse.

- Most of the constellations were identified long ago by the stargazers of Ancient Babylon and Egypt.
- Constellations are simply patterns — there is no real link between the stars whatsoever.
- Heroes and creatures of Greek myth, such as Orion the Hunter and Perseus, provided the names of many constellations, although each name is usually written in its Latin form, not Greek.
- The stars in each constellation are named after a letter of the Greek alphabet.
- The brightest star in each constellation is called the Alpha star, the next brightest Beta, and so on.
- Different constellations become visible at different times of the year, as the Earth travels around the Sun.
- Southern hemisphere constellations are different from those in the north.
- The constellation of the Great Bear — also known by its Latin name Ursa Major — contains an easily recognizable group of seven stars called the Plough or the Big Dipper.
- There are 88 official constellations which are recognized by the International Astronomical Union.
- Some constellations are only visible in the northern hemisphere, while others are only visible in the southern hemisphere.
- Constellations that are visible in both hemispheres may appear upside down in the southern hemisphere.
- A few constellations can be viewed all year long but most are seasonal and can only be viewed at certain times of the year.
- Distant galaxies and nebulae also form parts of constellations.
- Asterisms are groups of stars that form patterns but are actually part of one or multiple constellations, the Big Dipper is the most famous example of an asterism.
- The sun is the only known star in our galaxy which is not part of a constellation.

Uses of Constellations
- Constellation are useful because they can help people to recognize stars in the sky. By looking for patterns, the stars and locations can be much easier to spot.
- The constellation had been used in ancient times. They were used to help keep track of the calendar. This was very important so that people knew when to plant and harvest crops.
- Another important use for constellation was navigation. By finding Ursa Minor it is fairly easy to spot the North Star (Polaris). Using the height of the North Star in the sky, navigators could figure out their latitude helping ships to travel across the oceans.
