Personally, I do not send unencoded passwords in emails. In this particular case, you triggered the AI activity. The response you got was a summary generated "on the spot" by AI from the material you had searched for. I would wonder if that AI instance had the ability to update its learning...

Whenever you know the molecular structure (ie, the 3D positions of the atoms within the molecule), then you can immediately determine whether it is chiral or achiral - it's just a quick geometry exercise. Once you determine that it is chiral, and it is either transparent or can be dissolved in...

Hello 8938: It sounds like you have already investigated most alternatives. I think that any option you take has to compete with simply buying bottle water - In my area, Walmart sells a 5-gallon bottle for $13.48. I also Googled "can potassium be precipitated from water". There is a short list...

I was hoping one of the PF QM experts would catch this one. But let me take a whack at it. The actual refrigeration techniques are described in this wiki article on laser cooling. Of course, once refrigerated, the atoms will tend to warm up for reasons explained in the OP. Regarding QM...

I wasn't going to get into his theremin design. But if we do, why would we use a phase array instead of two or three directional antennae? This really looks like a rabbit hole.

You need two radio receivers. Each receiver will include an antenna and some circuitry. The channel width is described in Hz. So, if one of your receivers is tuned to an 800.1Mhz center frequency, then it will be sensitive to a range of frequencies around 800.1MHz. To make this simple (and it...

What device are you using to detect these pulses? Can that device be tuned to either carrier frequency? When you device is tuned to a carrier frequency, how wide is the channel that it is receiving? Since that frequency channel does not have an abrupt low and high limit, it is usually plotted...

Perhaps I don't understand exactly what you are aiming for, but the "beating of the carriers (100 MHz)" isn't commonly considered a problem. In fact, I thought you would want to stay in a narrow band - so I was thinking something like 800MHz and 800.1 MHz. And now that you are posting that you...

Scott's my first name. It's not customary to post a full name in PF, so I won't. But, as a software engineer, ctor would be a fine middle name. It is a commonly used abbreviation for "constructor" - the kind used in C++ (and, more generally, object-oriented) programming. I have never been...

I think the term may be "insurance". It's certainly a very, very common strategy. Normally odds are computed based on the common accepted value of the wager and return. But personally for the gambler, a $5 weekly wager will have no impact on his/her style of living - it may even provide a...

I think you might as well go with two carrier frequencies. Either way, you will need two beam-forming circuits that are independently gated then added together. Especially with only 16 elements, you should get fewer artifacts with separate frequencies - you will avoid regions of unintended...

I wouldn't be. I was only stating that in all other cases, there would not be perfect alignment.

To the question I posed in the OP. Yes, information about gravity will follow the same path as the light. And gravity will be affected by the gravitational lensing. But, with or without the lensing, only when the I am moving directly towards or away from the gravitational source (or hovering...

With Google, I could only find mention of BP3MV1-3X CVS (note the "1"). And apparently, that model has been discontinued. But the term "gentle measurement" is associates with "Inflation Mode Technology (IMT)" There is a a Microlife product with that technology, the "BP B3 Comfort PC". So far...

Besides being very comfortable with machines, the kiosk was probably the most relaxing method. I could take my time. The sign suggested relaxing for 30 seconds before starting - I relaxed longer than that. And, as I said, I took many measurements. Still, it is possible. I remember 30 years...
