  • 624 BCE

    Thales of Miletus

    Thales of Miletus
    Thales of Miletus lived from 624-547 BC, he was the first Greek
    astronomer and mathematician and was
    considered by many to be the first scientist of
    mankind
  • 500 BCE

    Leucippus and Democritus

    Leucippus of Miletus and Democritus of Abdera, their primary contribution was that they stated that all things that surround us is called matter and that we are made up of small particles.
  • 400 BCE

    Aristotle

    Aristotle was born in 385 BC and died in 322 AC in between those years he made a lot of contributions to physics such as creating his own school in Athen called The Lyceum in which physics and philosophy where principally teach
  • 300 BCE

    Aristarchus of Samos

    Aristarchus was born around 300 BC and died around 230 BC, he started theorizing about the movement of the earth and questioning how our solar system its really, after all this theorizing he proposed the theory of Heliocentrism.
  • 287 BCE

    Archimedes of Siracusa

    Archimedes was born in 287 BC and died in 212 BC, he is known for working mainly on statics and hydrostatics, in addition to astronomy and optics.
  • 85

    Ptolemy

    Born in the year 85 and died in165, he was a famous Egyptian astronomer and philosopher of the second-century one of his greatest contributions was the geocentric model that stated that the Earth is the center of the solar system.
  • 1473

    Nicolaus Copernicus

    (1473-1543) He proposed the heliocentric planetary system in which he stated that the sun is the center of our solar system and the other planets go around the sun.
  • 1564

    Galileo Galilei

    Galileo Galilei (1564 - 1642) reinforce the theory that the sun is the center of our solar system and the earth and other planets revolve around it, to prove it Galileo design and built his own telescope and discover a lot of other things that without the telescope wouldn't be possible.
  • 1571

    Johannes Kepler

    Johannes Kepler (1571 - 1630) proposed the three laws of planetary motion between 1609 and 1618. In them, he states that the planets of the solar system move in elliptical orbits. Kepler also
    contributed to the study of the physics of optics.

  • Isaac Newton

    Isaac Newton (1643 - 1727) made huge contributions to the physics world such as the 3 laws of newton which explain the movement of objects, he also explained that the attractive force called gravity which causes things to fall to the ground and stay on the Earth.

  • Benjamin Thompson

    Benjamin Thompson (1753 - 1814) proposed that the heating caused by friction was due to the conversion of mechanical energy into thermal energy.

  • John Dalton

    John Dalton (1766-844) considered that all things were
    made up of small particles called atoms, an idea that was accepted by other scientists, constituting the atomic theory

  • Hans Christian Oersted

    Hans Christian Oersted (1777-1851) make a lot of contributions not just to physics but also to electromagnetism, he discovered that when an electric current flows through a conductor, a magnetic field similar to that of a magnet is generated around it.

  • Michael Faraday

    Michael Faraday (179-1867) discovered induced electric currents, which are produced when a conductor moves transversely (perpendicular) to the flux lines of a magnetic field

  • James Prescott Joule

    James Prescott Joule (1818-1889) established the principle called the mechanical equivalent of heat, which made it possible to establish the law of conservation of energy, which indicates that the energy existing in the universe is a constant quantity, which is neither created nor destroyed, it only transforms

  • James Clerk Maxwell

    James Clerk Maxwell (1831-1879) was the first to propose that light is made up of electromagnetic waves, which can propagate in a
    vacuum without the need for a material medium.

  • Henri Becquerel

    Henri Becquerel (1852-1908) discovered radioactivity when he observed that the atoms of the element uranium gave off smaller particles, with which he considered that the atom was not the smallest particle, but that it was also constituted by other particles. This leading to the opening of a new field called atomic physics which in charge of studying the constitution of the atom.

  • Max Planck

    (1858-1947) is recognized for his contributions to theoretical physics, he is the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes.

  • Albert Einstein

    Einstein (1879-1955) developed a theory of special and general relativity, which helped to complicate and expand upon theories that had been put forth by Isaac Newton, Einstein also discover and explain the Photoelectric effect, a phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation
