📆 July 12, 2023 started in 📆 February 2021 at the Goldstone, , Complex (with
capabilities, which will be critical to communicate with 👨‍🚀👩‍🚀 traveling to 🔴). NASA cannot use communications to carry higher data rates like those required for Mars without increasing
the size of its antennas 📡 or power of its radio transmitters. Therefore, the Agency is developing communications (use
of light as a means of transmitting information through ) oig.nasa.gov/docs/IG-23-016.pd

So....top of the line Varilux progressives for about $478 (w/ insurance, lenses only) or good ol' Costco frames and prog. lenses (proprietary?) for less than 300.?
That's my current dilemma.

De la magie ? Non, c'est de la science, rien que la science ...
Lorsqu'un objet (ici, un verre, un tube à essai) est immergé dans un liquide (ici, de l'huile), si l'indice de réfraction de l'objet correspond à celui du liquide, la lumière à l'interface entre l'objet et le liquide ne sera ni réfléchie ni réfractée. En conséquence, l'objet semblera invisible.
