I disagree with your point #2 as it is written. You want to keep you battery close to the temperature at which it is rated. Cycling below that also harms batteries and shortens their life. If you really want to geek out about that, I can re

Carved from antlers. What tool would you use to make such clean, deep, small, circular features such as the pips and eyes on the figurine?

Yes I do, all the time. Your post and the comments it elicited reminded me of the excerpt from Adam Smith's Weath Of Nations about the Woolen Coat. It is given as an example of what can be achieved thanks to the division of labor. I to

OK, I see. I still find that surprising because I would imagine having the pipette hanging from your mouth doesn't allow ou to really see what is going on if you are really trying to hit a target volume. I would have thought the feedba

I am surprised there is on mention of rubber bulbs. If the main concern is safety, as the beginning of the article seems to imply, the rubber bulb would have been enough of a solution. The micropipette solves mostly all the other concerns:

Can you elaborate: why are the rings not visible on that image? Is it because they are outside the frame, or too faint, or don't appear in the visible spectrum? Something else?

I don't quite believe the dice roll metaphor tells the whole story. It is not all or nothing, it is not how it is done. On that subject, I recommend reading the book by Ed Viesturs [1], first American to ascend all 14 highest mountains

On this page you can select "State" (in Area Type) to zoom in on California. Compare this March 7 2023 to March 8 2022 and March 9 2021 to see the effect of the recent rains on the severity of the drought. For this time of year, t

For sure. I was just bringing numbers to support the >25% number claimed higher, and that it is not a matter of visibility. I frequently find people seem to think the homeless are simply more visible in California. Also didn't want

You bring up visibility of the homeless, that is one thing, but it is besides parent's point. There are government statistics on the homeless population and California has a huge share of it. See the 2022 HUD report [1] (also note the

On the very practical side: - Separate clearly preparation time from execution time. Prepare your pitch. Prepare a nice long list of targets with the relevant information (why you picked them) + contact info. Make it so you don't have

Good overview of the battery research space, with insights of what makes it hard to go from lab prototype to commercial product and why so many research breakthroughs eventually fail to translate into innovation for the consumer.
