To be honest, the examples stuck with me. They illustrated tons of different social interaction examples that I have seldom, if never, encountered in my life, but have plenty to learn from.
If we launched a second New Horizons when the last one passed Pluto, the second one would already have passed Pluto as well.
Crazy to think how much time has passed since that flyby.
Also, one of the program managers was on The Moth podcast describing the panic when new Horizons rebooted days before the flyby.
NASA's New Horizons spacecraft launched on January 19, 2006, and performed its historic flyby of Pluto on July 14, 2015. This journey took 3,463 days (approximately 9.5 years).
Buzz Aldrin (?) was quoted as recalling holding a pencil inside the capsule as they were out in space and thinking "that wall isn't very thick or strong, I could probably jam a pencil through it pretty easily..."
Death being a layer of aluminum away changes your mind.
Since we're talking trees. Only trees that grow in an area with distinct warm/cold cycles have rings, tropical trees don't and the only way to tell the age of most tropical trees is to have planted it yourself
Trees that grow in areas with wet/dry cycles also have rings. And since most of the trees from permanently-wet areas also have some kind of annual or semi-annual cycle, I'd guess the ringless ones are a rare exception everywhere.
Palms and Bamboo are technically "very big weeds". They are more related with grasses than with pines and never have rings. Bananas are also just giant herbs.
So Monocots don't have rings. Anything else that is a tree in a tropical forest has rings. It does not matter where they grow. The rings are smaller in slow growing species, and are different structurally in conifers, but this is all.
Wouldn’t a tree without rings still reasonably capture the atmospheric C13:C12 ratio as it grows? Or is the carbon motility within the trunk too high, or the ratio differences too small, to sample a bit near the core and use the ratio there as an age indicator?
Could be (I have no idea), but it sounds like that would be possible to investigate only by complicated laboratory tests. Not a visible change that makes it easy to calculate age by just sawing up a cross section and counting visible rings.
It's fun to be on vacation and go visit one of these. They're usually not in tourist areas and are likely to be in well established neighborhoods that a a different vibe than home. Also fun to read and come home with some random book that anchors you to that trip.
yeah! I've done some geocaching (or even just walking around exploring) while on my travels, and have very often encountered these "leave one, take one" type of free libraries along the way. It's really interesting to find different types of books depending on the area - the small town on an island of course has all these books on marine travel, sailing, that sort of stuff, for example. Nice way to get a little extra idea of the area and its culture, sometimes.
It just depends on if you're on the up portion of the K or the down stick. The larger picture might show an increase but if you split the data apart one leg is actually declining while the other is growing.
while an important consideration, I'm sure there are many on the up side of the k-economy that don't believe that persistent surveillance is warranted or ethical.
Molasses was cheap because it was the packing material for plate glass - which was only made in England. Place your plate glass in a barrel, fill it with molasses and you can ship it to North America. Just wash off the glass and you're good to go.
Jumping Jehoshaphat! The stained glass window up front is a memorial to George Jehosephat Mountain, a British-Canadian Anglican bishop. It was installed in 1864 and was the first monument of its kind in Québec. “The window was made in England and shipped to Québec City in barrels of molasses to protect it from damage.” A sticky situation, indeed.
The earliest ecclesiastical windows in Ontario are clear – likely English crown glass, such as is found at the Sharon Temple (1825-31) and the Old Stone Church (1840-53) in Thorah, near Beaverton. This glass was safely shipped from England in barrels of molasses, already cut to size. Coloured glass began arriving shortly thereafter. Using materials at hand, early windows were assembled within wood muntins (strips). Examples include the glorious windows in the chapel of Our Lady of the Sacred Heart Convent, Ottawa (1887), designed by Georges Bouillon and re-erected in the National Gallery of Canada in 1988.
If you strum an electric guitar and let the hertz of the string fall through the range of AM radio the amp will briefly pickup AM radio stations. Not that you can decipher anything but you recognize voices as it travels past the station.
That's not because of the frequency of the guitar but because the guitar functions as a very nice antenna (long piece of metal (the strong) + a coil forming a tuned circuit), what happens is that your hands create a very temporary partial diode where you touch the strings!
Such naturally occurring diodes are an interesting phenomenon (in this case: the salt in your sweat interacting with the steel of the strings) and were the basis of the very first radio receivers after the 'Coherer' (which is a word that has fallen out of use so far that it registers as a spelling error on my browser!).
How so? A guitar doesn't go past a few kHz (the highest string is IIRC 660 Hz, and the top fret is 660*4) and AM long wave radio—which is almost dead—starts around 120 kHz.
