>"Importantly, that cylinder can be pulled out into a long skinny configuration about one foot tall (305 mm), or pushed down to form a ring about one inch tall by five inches across (25 by 127 mm).

In its long state – and when connected to electronics such as a transceiver, ground plane and battery – the antenna emits a low-power signal in all directions, allowing for radio communications with ground-based team members. In its short state, it sends a high-power signal in a specific direction, allowing for satellite communications.

The frequencies utilized in either state are determined by the exact dimensions of each individual antenna."

Isn't that weird and interesting?

An antenna which can transmit in two distinct "dispersion modes" depending on shape and frequency...

In "wide-dispersion mode" (for lack of a better term), it is a standard transmitting antenna, probably subject to the inverse square law (https://en.wikipedia.org/wiki/Inverse-square_law), that is, not unlike the radio frequency analogue of incandescent light -- as might be emitted from an incandescent light bulb...

In "narrow-dispersion" (AKA "focused" AKA "beam") mode -- it is no longer subject to the inverse square law(!) -- and is not unlike the radio frequency analogue of a laser beam!

What's amazing (to me!) is that apparently (if this article is true!) frequency makes all of the difference between dispersion modes -- relative to size and shape.

In other words, perhaps it is possible to get a laser to act more like an incandescent light soruce if its frequency is changed, and conversely, perhaps it is possible to get an incandescent light source to act more like a laser, again, if its frequency is changed. (Of course, in the latter case, we'd need to start with a single frequency since incandescent/white light is by definition multiple frequencies...).

And perhaps this same effect is possible across all frequencies (RF, infrared, ultraviolet, etc., etc.)...

This antenna/coil design seems very similar to something called a "Caduceus Coil", which I first read about on the now defunct Keelynet BBS/website, a copy of one such file is here: https://www.newphysics.se/archives/keelynet/energy/caduceus....

Related (future) question: Under what conditions, exactly (exceedingly rigorous definition required!) is a coil (AKA "inductor") in a circuit also an antenna -- and conversely, when exactly is an antenna in a circuit also a coil?

The "Hopf Fibration" -- might be related to all of this:

I wish I had a use for this, GIS tools usually don't have such a level of polish and intuitiveness. I could maybe see building a capable data viewer on Placemark as a base, but I would be ignoring half its features at that point.

Makes me think of electric fence tape

https://store.am.gallagher.com/am/us/en_US/animal-management...

which has metal fibers woven into a mesh of plastic fibers. Even though the structure is mostly non-metallic I think it gives a better shock than a plain wire. I think I'm going to try making a ham radio antenna using that stuff.
It's just strips of thin metal and thin 'plastic', insanely cheap to produce and replace if they get damaged.

Dishes are also fairly easy to damage, especially if they're torn down and moved.

That said, what's shown isn't 100% of the antennae, you need a ground plane disc that the helix is attached to and acts as a reflector.
You're probably getting downvoted just because of Azure, but you are right. ADX/Kusto and KQL is an extremely powerful query language that answers exactly what OP questions about SQL.

Here's an example of a KQL query that I have in my browser...

Things
| where DeviceTags has "Installed"
| order by LastHeardFromTimeStamp desc
| take 10

KQL also takes ideas from R's Tidyverse and magrittr package. It takes datasets and pipes them into a new function. Like this...

car_data <-
mtcars %>%
subset(hp > 100)

From the Microsoft auto downvoters out there, all Azure dashboards and infrastructure analytics run on KQL (think Graphana, but on Azure). There are billions of KQL queries executing continuously, so it is absolutely a good example of a non-SQL query language that is active and mature.

I've been doing variations on this for decades. I'm fortunate enough to live in a rural area in the US with open space within walking distance, but I've done it in urban areas too. Some ideas:

- Walk every road and alley in a small town.
- Bicycle every unpaved road in an entire county.
- Follow every trail in a park.
- In an unfamiliar city, try to walk to destinations with minimal map or GPS use. This can occasionally lead to feeling unsafe, so use care. Before ubiquitous GPS, I used to carry a compass everywhere to help with this.
- Pick a direction and walk for a fixed amount of time, then come back a different way. I once walked 50 blocks in NYC this way during a business trip.

A friend of mine has spent many years hiking to the top of every publicly accessible peak visible from a hill near his house and has had some wild adventures as a result.

I used a PSOLAR Heat Exchange Mask (https://www.amazon.com/PSOLAR-Heat-Exchange-Mask-Full/dp/B00...)

for high altitude mountaineering and it worked very well for keeping warm but it didn't work like that and wasn't really a 'Heat Exchanger'.

What it actually had was a moisture absorbing substance stuck on a plastic comb like structure.

When you breathed out damp air from your lungs the substance would absorb the moisture and when you breathed in dry air it would release the moisture making it more humid.

This actually made a big difference to body heat as breathing in cold dry air onto hot moist lungs is very cooling from evaporation.

It also stops your lungs drying out. If you read Everest books they all get dry lungs and chest infections the the psolar thing seemed pretty good at stopping that.

I get the impression these are similar - really moisture exchangers and the 'heat exchanger' thing is marketing.

Things are records / rows. Collections of the same things are entities (rubber band/ folders). Groups of entities are tables (Drawers).

A star schema usually contains one table to one entity mapping.

Dynamic tables for custom field on the other hand are usually multi entity tables. In this case, it would be a large junk drawer with various unrelated folders stuffed inside with everything from report cards, to keys to toys, to take out menus. It would have the toys entities, take out menu entities, keys entities, etc inside a mixed table.

This is a specific issue of a general problem of AI/computer judging, where humans think they're judging on specific criteria, and write it into the computer, without ever taking a moment to ask whether that's actually what they want.

I use speeding in vehicles a lot. The point of a 55MPH speed limit isn't really that cars should be going exactly 55MPH at all times. It's an approximation of a complex situation that could handle only one number. But it's not actually a law of physics. Rigidly handing out tickets for people doing 56MPH is missing the point of speed limit. (As are many of the "You're doing X over" flashing signs, generally put in places that are precisely where the speed limit is too low and what people are doing is actually fine.)

Now that we finally have the technology to determine whether a gymnast was or was not one millimeter over some line, the question should be raised, is that what we actually want to judge on? Because just because we humans thought we were judging on that, just because we thought that's what we wanted, is it really?

It is this examination step that has been missing in every rush to insert computers into some judging system. We thoughtlessly reify accidents of history and what used to be easy to judge. At least in the case of gymnastics we're not going to send anyone to jail because of such thoughtlessness, but the sport could be destroyed. In the end, it still needs views, however abstracted the sports may seem to be from that, and after the novelty wears off, seeing humans out there competing for the most robotic and soulless performances runs the risk of gradually, but steadily, destroying all support for the sport.

Now, personally, I'm not sure this wouldn't be a net gain for humanity in this particular place. But it's certainly not what the gymastics community as a whole wants and they really need to slow down and apply some thought to what they really want before they let someone reify that into code.

They won't. Nobody else is either, for things far more important than this. But they should.

Again, I completely understand. Something is taken from you, and the whole song and dance leading up to it can amplify the negative associations.

You have agency in this situation and should inform and communicate your anxieties to any attending nurse or physician, possibly in advance. There are guidelines and support protocols in place exactly because of the strangeness some medical procedures invoke.

At the same time, their (slight) discomfort is the 'price to pay' for a mind at ease. My advice: try and rationalise it to a fault. I'd wager millions have blood works taken each day, and are only better for it. You will be among them.

Dare I say, I've even learned to be intrigued by those little vials whenever I have my blood works done -- so much information can be gathered from so little. A life in need can be a beneficiary from less than a minute of your time.

There is a science to gymnastics. However the judging is only minimally based on the science and mostly subjective.
The original paper is pretty clear that they're talking about killing plants, not just weeds, but that it might be useful for targeting weeds with it.[1]

Roundup, which they mention, is another example. It kills anything leafy (that isn't Roundup ready), but people call it a weed killer anyway.

Yes in power systems, automotive, tooling and machinery, and chemicals.

> Inflation can be seen as just the increase in money supply or an increase in prices.

Not quite. Price measures the values of the items being exchanged on both sides of the transaction. If you buy my widget for $1 today, and tomorrow you buy another for $2, that could mean:

1. The value of the currency has decreased.

2. The value of the widget has increased.

3. Some combination of both.

Inflation is only concerned with #1 and we attempt to suss out only the currency component by observing the change in price over a wide range of items frequently transacted for currency, which in practice typically means watching consumer purchases. If you see a general rise in price across all of what you are watching, it is quite likely that the change is a result of the change in value of the currency. If only one good in a basket goes up in price in those observations, it is likely that it is said good that became more valuable, not that the currency became less valuable.
