vector
In mathematics and physics, a directed quantity that is represented by an arrow and has both a length (magnitude) and a direction. Vectors are used to describe displacements, velocities, or forces.
Um die Kraft zu beschreiben, müssen wir einen Vektor mit Betrag und Richtung angeben.
To describe the force, we have to specify a vector with magnitude and direction.
vector
In biology and medicine, an organism (e.g., an insect) that transmits pathogens from one host to another without becoming ill itself.
Die Mücke dient als Vektor für das Dengue-Fieber.
The mosquito serves as a vector for dengue fever.
vector
In genetic engineering, a means of transport, often a plasmid or virus, used to introduce foreign DNA into a cell.
In der Gentherapie wird ein viraler Vektor genutzt, um das intakte Gen in die Patientenzellen zu bringen.
In gene therapy, a viral vector is used to bring the intact gene into the patient's cells.

'Vektor' (vector) is a technical term used in various scientific disciplines. It rarely occurs in everyday language. The exact meaning always depends on the specific field.
Im Studium mussten wir lernen, was ein Vektor ist.
At university, we had to learn what a vector is.
The word comes from the Latin 'vector', meaning 'carrier' or 'transporter'. This basic idea of transporting connects all meanings: a vector 'carries' a direction (mathematics), a pathogen (biology), or a gene (genetic engineering).
Man kann sich einen Vektor als eine Art Transportmittel vorstellen.
You can imagine a vector as a kind of means of transport.
You can recognize the meaning clearly from the topic. In mathematics, it is about arrows and directions. In biology, it is about the transmission of diseases by animals. In genetic engineering, it is about changing DNA.
Der Pfeil stellt den Vektor der Geschwindigkeit dar.
The arrow represents the velocity vector.
Zecken können als Vektor für die Krankheit FSME dienen.
Ticks can serve as a vector for the disease TBE.
In a mathematical context, a vector is often combined with verbs such as 'berechnen' (to calculate), 'zeichnen' (to draw), 'addieren' (to add), or 'multiplizieren' (to multiply). The nouns 'Betrag' (magnitude) and 'Richtung' (direction) are also typical signal words.
Die Aufgabe ist, die beiden Vektoren zu addieren.
The task is to add the two vectors.
sponsor / carrier
Träger refers to a living being that carries a pathogen and may pass it on, often without showing symptoms itself. Vektor is defined by its role in transmitting the pathogen from one host to another. Use “Träger” for carrying the pathogen and “Vektor” for the transmission role.
Die Mücke ist ein Vektor, weil sie den Erreger von einem Wirt auf einen anderen überträgt.
The mosquito is a vector because it transmits the pathogen from one host to another.
Der Patient war ein symptomloser Träger des Erregers, ohne ihn bisher weiterzugeben.
The patient was an asymptomatic carrier of the pathogen and had not passed it on so far.
