Kind of wild to announce but, I just got another paper published! First experimental demonstration of a spaceplane, with a compression factor of up to 175. Check it out, it’s real!! #photonics

The senseless attack on a Jewish woman in an Ottawa grocery store this week is deeply disturbing. My thoughts are with her, her family, and Ottawa’s Jewish community, and my support is with law enforcement as they work to swiftly bring the perpetrator to justice.
To Canada’s Jewish community: you are not alone. We stand with you against hate and threats to your safety, and we will act to confront antisemitism wherever it appears.

How can quantum entanglement be instantaneous (so, “faster” than the speed of light) while also not violating causality?
John Bell gave a classic analogy: "When the Queen dies in London, the Prince of Wales, lecturing in Australia, becomes instantaneously King".

TIL that the no-hair theorem actually hasn't been fully proven quite yet. It has in some limited cases, and even in the case of gravity without electromagnetism, it has only been partially resolved.

A great video on extreme nonlinear optics and the GZK limit (?), featured on the xkcd youtube channel.
What if we shined collimated gamma ray bursts on to the moon?

Mindblowing that we invented this word, and now it's part of the sum of human knowledge

Suigi just became the first person to hold all 5 main category speedrun records in Super Mario 64 at the same time. This is an unbelievable achievement, and one that seemed completely impossible a few years ago.

When you step out of a mall and people stare as you film a door, they may not realize the beauty of math behind a moiré optical illusion. It's a reminder that sometimes the most mesmerizing things are hidden in plain sight. #OpticalIllusion #MoiréEffect"

Thanks to all my coauthors! And special shoutout to @NKMandsberg for the snazzy TOC image. Does it remind you of anything? ;)

Aww these guys probably thought they had an idea that would get them into Nature, and instead found a non-result 😭
