😂 A Bright Joke

Fragt der Lehrer: "Was ist schneller, Licht oder Schall?"
Schüler: "Natürlich das Licht! Man sieht ja auch den Blitz, bevor man den Donner hört."
Lehrer: "Sehr gut! Und warum ist das so?"
Schüler: "Na, weil die Augen weiter vorne sind als die Ohren!"

Teacher asks: "What is faster, light or sound?"
Student: "Light, of course! You see the lightning before you hear the thunder."
Teacher: "Very good! And why is that?"
Student: "Well, because the eyes are further forward than the ears!"

(Okay, the joke isn't directly about 'Helligkeit', but about light!)

📜 Poem about Helligkeit

Die Sonne steigt, vertreibt die Nacht,
hat neue Helligkeit gebracht.
Ein Strahl fällt warm ins Zimmer rein,
so klar und hell muss Leben sein.
Die Lampe glüht, der Schirm erhellt,
was uns im Dunkeln sonst gefehlt.

The sun ascends, dispels the night,
has brought new brightness, pure and light.
A ray falls warmly in the room,
so clear and bright, life must assume.
The lamp aglow, the shade illuminates,
what darkness otherwise dictates.

❓ Riddle

Ich habe keine Stimme, doch vertreibe die Nacht.
Ich habe keinen Körper, doch erfülle den Raum mit Pracht.
Man misst mich in Lux, mal bin ich sanft, mal grell.
Was bin ich, das Gegenteil von Dunkel?

I have no voice, yet I banish the night.
I have no body, yet I fill the room with delight.
Measured in Lux, sometimes soft, sometimes stark.
What am I, the opposite of dark?
