Here's a shorter X version:
I present to you the largest storm in the Solar System. 🪐🌪️
Jupiter’s Great Red Spot is a giant storm that has raged for at least 190 years, with winds exceeding 400 mph (640 km/h). Though it's slowly shrinking, it remains one of the Solar System’s greatest mysteries.

The lens-maker’s equation,
1/F = (n - 1)(1/R1 - 1/R2),
gives the focal length of a thin lens using the refractive index n and signed radii of curvature, positive when the center is to the right of the surface.
For converging lenses R1 is positive and R2 negative, focusing parallel rays at a real focal point on the right.
For diverging lenses the signs reverse on R1 and R2, producing a negative focal length where parallel rays diverge from a virtual focal point on the left.
It is used to calculate the curvatures required for eyeglass lenses correcting nearsightedness and farsightedness.
