So I bought 2 sets because it looked like one set was briefly lost in the mail and this past week I got an email from Amazon that said one set I bought were “fakes.”

• Both sets have printing that matches legitimate manufactures.
• The “legitimate” set have all black filters (not the metalized filters I am used to like Thousand Oaks Optical) the “fakes” have the metalized filters.
• Both sets of glasses have the same transmittance as the Thousand Oaks filter material I use on my telescope and cameras.
• The build quality of the “legitimate” glasses is quite a bit worse than the “fakes” with the two layers of paper being misaligned

So, what I suspect is that I actually received a crappy set of “real” glasses and a well made set of counterfeits, this seems in line with the press release made by the American Astronomical Scociety.^[0]^

Some of these newly identified counterfeits are indistinguishable from genuine Qiwei products and appear to be safe. Others look like Qiwei’s eclipse glasses, but when you put them on, you realize they are no darker than ordinary sunglasses. So, these products are not just counterfeit, but also fake –– they’re sold as eclipse glasses, but they are not safe for solar viewing.

So, did anyone get unlucky enough to get some ‘real-fake’ glasses? An did anyone get a set of legitimate glasses with the non-metalized filter?

In the ten years since I took this photo the trail has been abandoned and the tree has rotted away.

To prevent the possibility of being attacked in your home, leave your fobs at your front door, because they're breaking into your home to steal your car. They don't want anything else.

Totally unrelated to the Boeing that lost a wheel last week or the Boeing that had "a strong movement" today, injuring 50.

So many CRTs.

• 1/3 Whole wheat flour
• 2/3 White bread flour (all purpose works as well)
• 70% Mill Street Organic Lager (any light lager works)
• 2% Salt
• 1.5% Yeast

Bulk ferment for 2 hrs with one or two folds at 20min and 40min. Proof for 2 hrs then bake in an oven that was preheated with a cookie sheet full of water (careful of the scalding steam when you open the door). As soon as the bread is in the oven spray it down with way too much water (careful of your oven window) then close the door to trap all the steam. You should get some good spring and that nice crunchy/speckled crust.

Protip: 500g of flour is the perfect amount for a 355ml can of beer.

"Not every item within [the plastic manufactured items category] has the potential to create a reasonable apprehension of harm"

As long as we agree not to be apprehensive about the harms resulting from the use and manufacture of all plastics, they are ok. Got it, bring back the straws and stir sticks!

The challenge to the federal government’s proposed ban was brought last year by the Responsible Plastic Use Coalition (RPUC) and several chemical companies. They argued that the federal government had failed to demonstrate that it had enough scientific evidence to justify the regulations. RPUC was formed in 2021 in response to the “toxic” designation, and currently includes more than 30 processors and resin makers, including Berry Global Group Inc., CCC Plastics, Dow Inc., Ingenia Polymers, IPL, LyondellBasell Industries, and Nova Chemicals Corp.

TL;DR This is a drop of the solvent from pen ink dissolving into water and filmed at 1500fps, played back at 30fps, the field of view is 5-7mm ish.

Phenoxyethanol is the solvent in ball point pens that gives the ink it's distinct smell. It is just barely soluble in water and saturates at a very low concentration, it is more dense than water but small droplets will float unless the water is already saturated. It also has a significantly lower surface tension than water.

On first contact with water the droplet of phenoxyethanol spreads out and is supported on the surface. Soon after the edge of the droplet starts to split into dendrites that wave violently and send out extremely high speed ripples across the water. As the droplet shrinks and breaks up smaller arms form on the larger ones until the droplet wiggles itself into non-existence. What the hell is going on?

When the droplet first contacts the water it begins to dissolve and immediately saturates the area directly below the drop, at the edges of the drop the saturated solution is pulled away by the surface tension gradient around the drop. This gradient sets up a flow of unsaturated water up from below the drop and away, across the surface, both supporting the droplet and pulling it out wider and thinner. Tiny inconsistencies lead to the formation of of the dendrites, as the area between two arms becomes saturated they are pulled apart (and closer to other arms) leading to the rapid back and forth wiggling. This continues at all scales forming similar shapes on the scale of several mm down to fractions of a mm.

It took me weeks of messing around with the camera and reading about fluid dynamics to figure this out. I even spoke with a couple of fluid dynamics experts who both told me "hey, that's really weird, why does it do that?"
