## Pendulum

Weight suspended from a pivot so that it can swing freely.

Weight suspended from a pivot so that it can swing freely.

From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s.

## Observational astronomy

Division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models.

Galileo Galilei turned a telescope to the heavens and recorded what he saw.

## Speed

Object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Italian physicist Galileo Galilei is usually credited with being the first to measure speed by considering the distance covered and the time it takes.

## Physicist

Scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe.

Scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe.

The modern scientific worldview and the bulk of physics education can be said to flow from the scientific revolution in Europe, starting with the work of astronomer Nicolaus Copernicus leading to the physics of Galileo Galilei and Johannes Kepler in the early 1600s.

## Galilean moons

The Galilean moons, or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto.

The Galilean moons, or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto.

They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610.

## Telescope

Optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.

Optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.

The word telescope was coined in 1611 by the Greek mathematician Giovanni Demisiani for one of Galileo Galilei's instruments presented at a banquet at the Accademia dei Lincei.

## Jupiter

Fifth planet from the Sun and the largest in the Solar System.

Fifth planet from the Sun and the largest in the Solar System.

Jupiter has 80 known moons and possibly many more, including the four large moons discovered by Galileo Galilei in 1610: Io, Europa, Ganymede, and Callisto.

## Projectile motion

Form of motion experienced by an object or particle that is projected near Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are passive and assumed to be negligible).

Form of motion experienced by an object or particle that is projected near Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are passive and assumed to be negligible).

This curved path was shown by Galileo to be a parabola, but may also be a straight line in the special case when it is thrown directly upwards.

Galileo Galilei was the intellectual centre of the academy and adopted "Galileo Galilei Linceo" as his signature.

## Santa Croce, Florence

Principal Franciscan church in Florence, Italy, and a minor basilica of the Roman Catholic Church.

Principal Franciscan church in Florence, Italy, and a minor basilica of the Roman Catholic Church.

It is the burial place of some of the most illustrious Italians, such as Michelangelo, Galileo, Machiavelli, the poet Foscolo, the philosopher Gentile and the composer Rossini, thus it is known also as the Temple of the Italian Glories (Tempio dell'Itale Glorie).
