My grandmother is very afraid of birds. Very afraid, not a fan at all. And, for SOME reason, I don’t know why, my brothers invested in a life sized garden ornament of an owl. We don’t even have a garden to decorate, I have no clue why this is in the house, but in any case they put it in my mum’s room because it had the most space. My grandmother nipped in to get something and lo and behold; she spies the owl.

Naturally, she FLIPS. Slams the door shut, sprints to me, and then, all at once, the fear subsided as her brain kicked back in and told her it was an ornament.

But my mum was asleep in that room. She still is.

What my grandmother did was walk in, spy what she thought was a very real bird of prey and LOCKED MY MUM IN WITH IT

THE OWL IS YOUR PROBLEM; DON’T GET MAIMED

How do you prolong the useful life of lubricants?

Wind turbines towering hundreds of feet over many landscapes herald a future of endless, clean energy.

But in a crucial sense, turbines remain rooted in the past: Much like with your car, their engines require lubrication to run smoothly. The question for many chemical engineers is, how do you prolong the useful life of the lubricants?

In a new study published in the journal Proceedings of the National Academy of Sciences, Vineeth Chandran Suja, a Stanford graduate student in chemical engineering, explores one of the core problems: foaming oil.

The problem, he says, is that whether it’s in your car or a wind turbine, each time metal gears grind against other metals, oil gets sloshed around and mixed with air. This often results in the formation of tiny bubbles with varying lifespans. If the bubbles don’t immediately burst, they soon collect into a foam, which is one of the primary mechanisms of engine decline.

The foam is harmful in a variety of ways. It degrades the lubricant and allows gears to grind. Oxygen trapped in oil foams causes the metal parts to oxidize, that is, to rust. And the foam acts like a thermal insulator, trapping harmful heat in the system. Hence, lubricant manufacturers are actively looking for ways to mitigate lubricant foaming.

I had a rude-ass dream last night. Some disembodied voice said “Hey, wanna hear a funny joke?” I’m a fan of jokes and do what voices tell me in my dreams, so I say “Yeah, sure.” Then my 8 AM alarm goes off.

Prick.
