The Skeleton: Roles and Functions
The skeleton of an organism is not just a protective covering for the soft tissues and muscles. Besides facilitating movement, the bones also serve as a storehouse of minerals. […]

The Discovery of New Particles: Baryons and Quarks
With scientists continuously pushing themselves to widen their horizons of knowledge, newer particles were also discovered. The fundamental forces of nature, baryons, and quarks are some of the other concepts that were devised to understand the microcosm. […]

The Discovery of Proton and Neutron
Even after Rutherford’s discovery of atomic nucleus, the structure felt incomplete until he discovered the protons. With the mass still not adding up, James Chadwick experimented and succeeded in discovering the neutrons. […]

How the Nucleus of an Atom Was Discovered
While J. J. Thomson is hailed for his discovery of electrons, his student Ernest Rutherford holds the credit for another major discovery: the nucleus. His findings shed light not only on the structure of the atom, but also their size and volume. […]

The Physics behind Kepler’s Laws
Kepler’s laws of planetary motion are not really laws of physics. To understand the reason behind these laws, we need to consider Newton’s law of motion. […]

Kepler’s Second and Third Laws
Kepler’s second and third laws are about how fast the planets move and about the time required to go around the orbit, respectively. His third law helps measure the mass of everything in astrophysics. […]

Kepler’s First Law: Orbits are Ellipses, Not Circles
Kepler’s laws refer to the motion of the planets. His first law states that the orbits on which the planets move are elliptical in shape and not circular, as had been believed earlier. […]

Cepheid variables: The Powerful Beacons
Edwin Hubble was able to calculate the distance at which Andromeda nebula is situated using the Cepheids in it. He was able to do so owing to its angular size of a few degrees corresponds to a true size comparable to that of the Milky Way. […]

The Astronomical System of Units
Although while measuring distances between astronomical objects, one can use the unit arcseconds, however, parsec is more preferred as it happens to have the same order of magnitude as the light-year. […]

How Is the Solar System Mapped?
Radio transmitters help us when it comes to calculating and mapping nearby objects in our solar system. To map objects far off in our solar system the parallax equation is used. […]
