Wie hat Galileo Galilei die Welt verändert?

Tatsächlich gilt Galileo Galilei als „Vater der modernen Wissenschaft“, da seine bahnbrechenden Entdeckungen in der Physik und der Astronomie unsere Welt nachhaltig verändert haben.

So führte zum Beispiel den methodischen Einsatz von Experimenten ein, um Theorien wissenschaftlich zu untermauern. Das klingt für unsere heutige Zeit ganz normal und logisch, doch es leitete die grundlegende Abkehr von den vorherrschenden Lehrmeinungen und philosophischen Spekulationen seiner Zeit ein.

Außerdem stützten seine verbesserten Fernrohre und astronomische Beobachtungen und Entdeckungen der vier größten Monde des Jupiter, der Phasen der Venus und der Sonnenflecken, das heliozentrische Weltbild von Kopernikus.

Welche Bedeutung hat Galileo Galilei für die heutige Zeit?

Mit seinen Forschungen und methodischen Ansätze legte Galileo Galilei den Grundstein für die heutigen Naturwissenschaften. Er betonte schon früh die Bedeutung der Mathematik als Sprache der Wissenschaft – und seine Erkenntnisse waren entscheidend für das Verständnis der natürlichen Welt, wie wir sie heute kennen.

Wir können vor allem auch von seinem Mut lernen etablierte Glaubenssätze stets zu hinterfragen.

Tip: So ist es zum Beispiel aktuell noch gesellschaftlich anerkannt, dass wir Tiere essen. Doch es ist auch ein Widerspruch in sich, dass viele Menschen Tiere lieben, aber sie gleichzeitig auch für den eigenen Genuss töten lassen. Im weiterführenden Blogbeitrag habe ich mich intensiver damit auseinandergesetzt. Schau also auch da gern mal rein!
