Channeling Espresso

Coffee-making continues to be a rich source for physics insight. The roasting and brewing processes are fertile ground for chemistry, physics, and engineering. Recently, one research group has focused on the phenomenon of channeling, where water follows a preferred path through the coffee grounds rather than seeping uniformly through the grounds. Channeling reduces the amount of coffee extracted in the brew, which is both wasteful and results in a less flavorful cup. By uncovering what mechanics go into channeling, the group hopes to help baristas mitigate the undesirable process, creating a repeatable, efficient, and tasty espresso every time. (Image credit: E.

Shipping

It’s weird but I actually have two packages that have been shipped out by me over the last couple of days. One is a passport renewal form that went out via Fed Ex last night and the other is seven rolls of 35mm film* that I sent out via USPS on Saturday. Which will arrive at its destination first? The race is on! In this post-pandemic era of online shopping it’s common to be following packages that are on their way to you, but less common to have to follow packages that are on their way from you. Maybe not. I don’t know. I have to write about something.

Apparently you can spend six months in Scotland without a visa. Who knew? Ireland only lets you stay for three months. England and Wales are also six months, so is that a UK thing in general? What about Australia? I’ve recently watched two television shows that took place in Australia so I feel like I practically live there already. Duck Duck Go (fuck you, Google) says you need to obtain an Australian visa before you arrive. Well that’s no fun. Kevin Garvey, Jr and Nora Durst must have already had a visa when they left Miracle, TX on The Leftovers. Kevin Garvey, Sr… well who knows what that whack job was doing. He sure as hell didn’t.

The Bruins season ended last night on another painful loss. Some teams still have a game left to play, but my team is done. Mercifully. The best they can finish is tied with Philly for last place in the Eastern Conference. The worst they can do is finish in last all by their lonesome. Unfortunately for the draft lottery, there are 4-5 teams out west that will finish with worse records. Not that we have a General Manager who knows how to draft for shit though. In other Boston sports news, the Red Sox actually won a game last night after getting humiliated on Monday night. Fun.

I’m in the office today and tomorrow so the pickin’s for photo a day will be slim. Not that it matters. They are all just pictures of cats anyway. This one for today made use of the iPhone’s low light feature. It works well.

*35mm film refers to the size of the negative… I think. 120 film does not refer to the size of the negative. I read somewhere that it refers to an old Kodak catalog product code. Mentioning 35mm and 120 film in the same sentence makes my ass itch. It’s like doing your physics homework and mixing up your units of measure. It’s like referring to velocity (measured in meters/seconds) and acceleration (measured in meters/seconds squared) as if they were the same thing. I believe the product code for 35mm is actually 135 (not too confusing there, Kodak) but I don’t know what the negative size for 120 film is. I can’t bring myself to call 35mm 135 so I guess I will continue to mix units and have an itchy ass. I could say medium format instead of 120 but that just feels like taking it all a step too far. I don’t know.

Experience the double-slit experiment! In quantum mechanics, its statistical nature already appears if you consider single particles. You cannot predict where the next blip on the detector screen will appear. But after running many identical experiments, you will recover an interference pattern with clear maxima and minima. Try out this web applet to see for yourself.

💁🏻‍♀️ ICYMI: 🎈🧭 What was the first human-made object to break the sound barrier? And why do we always see the same side of the #moon? Mark Rober tackles these questions and more through creative experiments.

In this fast-paced #video, he goes up in a hot air balloon, tests liquid density with soda cans, drops metal in mercury, and even rides on top of a moving train to demonstrate scientific principles.
