If the buffer says 7.5 and it makes up 6 when mixed, either far too little of the buffer was used/there was already something else buffering the solution or the buffer was prepared incorrectly.

By selecting the correct buffer and the correct ratio of salt to acid (such as acetic acid and sodium acetate) an exact pH within a certain range can be reached.

Wish we got a more complete understanding of the truckers’ side in this article - why is it so hard to turn off your engine instead of idling?

The guy quoted in the article says that some trucks need to operate their lift gates 15 or 20 times in a day. First of all, turn on your engine to operate the gate and then turn it off when you’re done… Secondly, if it is impacting business too much to take that extra time to turn the engine on and off, invest in an auxiliary power source to operate the lift gate.

Maybe I’m missing something?

So what do you suggest? No cars allowed at all? Even in European countries with strong public transportation cars are still useful and allowed (except in crowded city areas). It’s hard to imagine life out in the boonies without access to a car…

I think we should pursue better public transportation primarily, but I also think efforts to make electric vehicles better are an important piece of the puzzle to transporting ourselves sustainably.

The bees were on a different lower down roof from the main roof (which is the one that burned). The article notes that bee wax melts at 70C and they didn’t see any of that under the hives, so they know temperatures stayed below that. So the bees were likely only exposed to some smoke and maybe some slightly elevated temperatures.

Tariffs on Chinese goods are a good thing. And I honestly see why the next logical step is tariffs on Mexico because Chinese companies are already building in Mexico so they can assemble there and ship across the border and circumvent tarrifs.

I think China manipulates markets and damages the global economy while making consumers feel like they don’t need to value the products they buy because they are so cheap. And I don’t think we should be letting China off the hook for the Uyghur genocide/gluttony of human rights violations.

Buy local. I wish it was easier to buy American manufactured stuff.
