Edge diffraction to single-slit diffraction in a closing door next to my office. I'm greeted by this happy natural phenomenon every day and finally decided to film it. #photonics #iteachphysics

I know that the NYT Spelling Bee is bad with scientific/technical terms, but this omission is particularly egregious. #photonics #NYTimes

Will the NYT please use a science dictionary?! This is getting ridiculous.

More common science words, please.

What is going on with the NYT Spelling Bee. This is Canadian erasure.

Is it just me, or is the Spelling Bee particularly frustrating for scientists?

Our new paper asks (and answers) whether a shallow-learning approach (decision trees) can be as useful in (hyper)spectral analysis as advanced deep-learning methods. tldr: Yes it can. Complex ≠ better. doi.org/10.1088/2515... via @ioppublishing.bsky.social #photonics

What kind of fresh hell is this? Dear Optics Express (@optica): I am not entirely confident that you understand the meaning of "final decision". To be fair, I'm also no longer sure that you know the meaning of "express". jkjk. Please don't Major Revisions this paper. We're sick of looking at it.

And for completeness--because the thermal camera only images the surface--here is a thermal image of the post-irradiated oils after stirring. Without garlic the oil heated from 24C to 45C. But a tiny mass of suspended garlic heated the oil to 75C! Beautiful convection boundaries abound 💡🧪 🧵 4/4

The glass bowl on the left is plain oil, and on the right is the same amount of oil with a minced clove of garlic. Both bowls were heated side-by-side on high for 35 seconds. 💡🧪🧵 2/4

The microwave oven isn't just for bad cooks! There are some great cooking hacks if you know the science! A minced clove of garlic in a quarter cup of oil, on high for 25 seconds, will yield aromatic garlic-infused oil without any browning or bitterness. 💡🧪 🧵 1/4

So many misconceptions about putting metal in the microwave oven. Yes, you can leave the metal spoon in your tea/coffee/soup/stew. No, it won't spark or burn you! In fact, the metal won't absorb any microwaves. [Pic is before & after, 45s on high. Temp scale on right is useful.] #iteachphysics 💡🧪

Torn between a pic of food, nature, optics phenomenon, or dumb meme as my first bsky post. I guess optics art wins. Here's polarization-filtered colouration (polage) piece I call Night Flood.
