They do conduct an experiment to control for both switching noise, or other feed-through transmissions. They put two 50 ohm terminators on as the load, and find the receiver gets nothing. They also try cooling down one of the loads in liquid hydrogen, and the transmission resumes.

If you want to encourage folks to continue their efforts and really "build something", I think you'd want to ask your questions in a way that shows genuine interest and support, rather than ridiculing and questioning the level of effort involved.

I agree, I'd love to learn where the dada was sourced! I'm also curious why it appears to come in waves, as opposed to each building going up independently (as I would have expected it to in reality). Cool idea! I can see my house from here haha.

It's important to also note, as explained in the article: >"Grinnell was witnessing the glacier react to a relatively natural change in the climate. The Little Ice Age, which was a cold period when the park’s current glaciers were at their largest, ended in the late 1800s as the climate started warming. The melting of the park’s glaciers in the late 1800s, was a mostly natural reaction to the end of the Little Ice Age."

The quote, without context, implied to me that he had an understanding of anthropogenic climate change a century ago. While there were people[1] at that time who did theorize this was happening, I don't think that's what Grinnell was implying in his diary.

It's also the case that the amount of melting then pales in comparison to the amount occurring today - so I'm not attempting to say that what we see today may be the continuing of a natural climate fluctuation.

I love it! I will absolutely be trying this out and following along.

For a long time I've used draw.io for making diagrams, and found it clever that you can effectively save your document as an iframe blob of editor + file (though in their case, the editor is not stored in the file, a web connection is required to load the editor codebase. I've wished that could be the primary use case and this is basically what I'd imagined!

One possibility: we have been collecting learning to use our feet less throughout life.

"In 1969, 48 percent of children 5 to 14 years of age usually walked or bicycled to school (The National Center for Safe Routes to School, 2011). In 2009, 13 percent of children 5 to 14 years of age usually walked or bicycled to school (National Center, 2011). In 1969, 41 percent of children in grades K–8 lived within one mile of school; 89 percent of these children usually walked or bicycled to school (U.S. Department of Transportation [USDOT], 1972). In 2009, 31 percent of children in grades K–8 lived within one mile of school; 35 percent of these children usually walked or bicycled to school (National Center, 2011)."
