Probably some combination of electromagnetic effects in that specific section. Happens to oscillate just right. Though these weights can be used for wind issues, I’m seeing a lot of references to dampening other kinds of vibrations. Might help you find a better answer.
Hmm. It’s odd that this isn’t ALWAYS vibrating, but it IS only between these two poles that I’ve noticed the vibration. But why not between other sets of poles? And since the cable vibrating the most isn’t a power cable (I believe it’s fiber, but it could be copper - but it’s definitely telecom, since it’s not insulated on the top crossbar, as the other power cables are), it can’t really be much power going through it. I’m kind of hoping someone else has seen similar behavior somewhere else. You can see the anti-wind-twist devices (don’t know what else to call them) bolted to the other telecom cable (sort of diamond-shaped) and they will cause the cable to stabilize when the wind is really blowing, but you can see the wind isn’t blowing at all, and the cable continues to vibrate quite noticeably. I really do hope someone else has seen something like it elsewhere…
In regards to it only being between those two poles, I’d wager it simply comes down to tension. The other cables are tensioned correctly and this section is either too loose or intentionally loose as some sort of expansion/contraction relief.
Is this real? I feel like some of the details on these things in the pictures look very macro. Like the colored striations on the shell pieces. Super cool if it is, but I’m not so sure…
Uh what? I mean we can get geochemistry and look for trace elements.
Paleontologists will absolutely look for fossils in sand, they do it all the time. I just sent off a bunch of sand and clay for pollen analysis and I’m not sure how they process it but I know it involves dissolving inorganic material in acid sometimes.
Most of the time no one looks at sand in bulk. It’s…you can imagine, a daunting task. Sometimes people (individuals) will look at sand for some diagnostic purposes - usually in my line of work to note the type and abundance of minerals present, or especially the distribution of particle size and clay/silt content. I know other fields will survey things like diatoms and foraminifera for paleontology but also for I think oil exploration because indicator fossils are important but I don’t do that so I’m not really sure I can speak more to it.
A lot of time people look at sand in the field with a hand lens or drag it back to the lab to look at it with a basic microscope. Or slap it in epoxy and make a thin section. Sending it off for geochemistry is…possible but may not be especially illuminating depending on what you’re trying to learn. People can also date the sand using optically stimulated luminescence (OSL) to get a date of when the sand was last exposed to sunlight (and thus, deposited) if the sand is in the right age bracket (<150ka ish).
Rarely people get more involved with things like XRD/XRF, SEM, microprobe uh… something else, I’m sure. That’s more of a straight academia realm though.
I went off on a tangent but people slap sand in machines and other things to find out stuff all the time.
Note: Only some types of sand from some places have an interesting appearance microscopically. Most sand will just look like little rocks. Or at least that iirc from the last time this image was circulating.
Oops, indeed, updated title from “Sand is beautiful under a microscope” since that wasn’t totally accurate. “Oops” because I had in fact suspected as much!
Turkish flag is an interesting case, as it’s nearly a 100 years older than Turkey.
The design has been used by the late Ottoman Empire, and then adopted when the Republic of Turkey (now regretting to itself as Turkiye) was established.
I’ll admit, I am no flag expert but is the union Jack is made up of a few different flags that surely have to be older? Scottish saltire, st Georges cross.
Here in Washington it’s hard to imagine waterfalls even being noteworthy. We’ve got way too many mountains and way too much precipitation. We’re lousy with waterfalls. The whole fuckin state is a goddamned waterfall.
