A study explores how wet foams “coarsen” in #microgravity, as many small bubbles combine into fewer large bubbles. Unexpectedly, the authors found that some small bubbles persist, roaming the foam. In PNAS:

Okay, I integrated some fake shader-driven fluid-filled balls into the Krant cockpit, added bubbles, and I quite like the result. A small detail, to be sure, but an interesting one.

I forget how many miss that when a propeller spins fast,it creates extreme low pressure on the blade’s back that water vaporizes. The collapsing bubbles create micro-jets at 100+ m/s. The bubbles are mini explosions. Reminder that there’s a lot beneath the surface.

This Hubble image features a small detail of N159 ✨ a star-forming complex in the Large Magellanic Cloud. Stars are beginning to shine through the cold, dark interior of the cloud. Some of them seem to lie within a reddish bubble. These bubbles are evidence of stellar feedback, in which young stars blast their surrounding with radiation and blow bubbles with their stellar winds! 🌬️ Read more here: 📷 European Space Agency / HUBBLE & NASA , R.

Bubbles happen when supply gets ahead of demand. Cerebras CEO Andrew Feldman says AI is the opposite. Everyone is chasing demand that already exists, with constraints in every direction. Bubbles don't usually start with a shortage.

When you flush, water flows down and drags air inside the pipe. Bubbles form, and the flow becomes unstable. This creates a partial vacuum in the system. That vacuum starts pulling air from the toilet itself. That’s why you hear that “glup” sound and even get gas backflow. Now, when the system has proper venting, everything changes. Air enters through the vent pipe and balances the pressure. Flow becomes smooth, with no bubbles or interruptions. No vacuum, no suction, and proper drainage. That small pipe is what prevents the entire problem.

This is why AI is not a bubble. Even a small drop in global labor costs is worth trillions. Capital is going into infrastructure that companies will depend on for decades. Bubbles bet on revenue that might show up later while this buildout is betting on expenses coming down.

We're not just living through a set of nested bubbles. This is the mother of all bubbles in all of financial history. Seeing what we're likely to face by 2028, it's a fair assessment to say that massive, wild, extraordinary changes are afoot, and that they're picking up speed. We're in the middle of the quickening.

One might think a raindrop could do serious damage to a tiny water strider. But a study shows that their low-density, hydrophobic exoskeletons allow them to surf jets and craters made by drops—or easily resurface if pushed underwater. In PNAS:

OpenAI CEO Sam Altman reportedly said that an AI bubble is forming. “When bubbles happen, smart people get overexcited about a kernel of truth,” Altman told The Verge. “Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes. Is AI the most important thing to happen in a very long time? My opinion is also yes.” Sam Vadas breaks down the details – and pops all the bubbles. 🫧
