### Sir Isaac Newton’s Discovery

Prime objective of this lecture is to present on Sir Isaac Newton’s Discovery. Sir Isaac Newton was an English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian and one of the most influential men in human history. As a result of his extensive contribu.....

### Hipparchus of Rhodes

Hipparchus of Rhodes became a famous astronomer in Alexandria. Around 150 BCE developed a new tool for measuring relative distances of the stars from each other by the visual angle between them. Hipparchus invented the table of chords, a list of the ratio of the size of the chord of a circle to .....

### Presentation on Ptolemaic System

Ptolemy’s system was purely geometric, like Eudoxus, with combinations of circular motions. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that the Earth is stationary and at the centre of the universe. Ptolemy’s system for each planet involves a large (imagina.....

### Lecture on Claudius Ptolemy

Claudius Ptolemy lived about 150 CE, and worked in Alexandria at the Museum. Like Eratosthenes, Ptolemy studied the Earth as well as the heavens. One of his major works was his Geography, one of the first realistic atlases of the known world. Ptolemy’s major work was his Mathematical Composit.....

### Kepler’s Laws of Planetary Motion

Kepler’s Laws of Planetary Motion says: The orbits of the planets are ellipses with the sun at one focus. And second,  A line from a planet to the sun sweeps over equal areas in equal intervals of time. Kepler used the precise observational tables of Tycho Brahe (1546 – 1601) to study planet.....

### Geocentric vs. Heliocentric System

Basic objective of this lecture is to present on Geocentric vs. Heliocentric System. Geocentric System narrate: the Sun, stars, and planets on their spheres revolve around the earth: explains daily movement; to account for unusual planetary motion epicycles were introduced. Heliocentric System d.....

### Presentation on the Copernican Revolution

General objective of this lecture is to present on the Copernican Revolution. In the heliocentric or copernican model, apparent retrograde motion of the planets is a direct consequence of the Earth’s motion. The story of Copernican Revolution is the classic example of a major shift in worldv.....

### Presentation on Neutrinos

The Sun produces a lot of neutrinos. It travel extremely fast. Almost at the speed of light if small mass. Neutrinos pass from the core of the Sun to the surface in only two seconds. They take less than 8.5 minutes to travel the distance from the Sun to the Earth. Neutrino detectors use hundreds.....

### Theoretical Explanation: Solar System

Principle purpose of this lecture is to present on Theoretical Explanation: Solar System. Ptolemy explain the geocentric model, that the Earth is at   rest at the center of the Universe. Copernicus published the heliocentric model. Galileo explain his observations by telescope verified the he.....

### Presentation on Solar Flares

Solar flares are a violent explosion above the suns surface. A large amount of energy is released. Solar flares may last for 10 mins and will produce more energy than a million hydrogen bombs. There is a peak in this type of activity ever 10-11 yrs, during which large numbers of charged particle.....
