Which you should be able to show mathematically. The next question is the limits on the integral. You imply it starts at t=0 (or it could be something quite small, like 10^-43 s) but the CMB didn’t exist until later. How do you reconcile this?

I will rephrase. You don’t show it in your integral. Will you do so? This is a discussion forum. Being coy seems to be the opposite of discussion.

I don’t see it in your integral

Random processes exhibit these distributions, not just decay The measurement would, or could, show systematic errors. I don’t think the process itself would Radioactivity involves nuclear processes; the nucleus spontaneously goes to a lower energy state and closer to stability, usually by releasing a particle or particles (the exception is electron capture, where it absorbs an atomic electron) Heat is energy transferred by an object owing to a temperature difference. It can be electromagnetic radiation but there’s also conduction and convection. Yes. Even though the trend of number of decays per unit time follows an exponential, the actual data will show deviations from that curve.

Since this wavelength has changed over time, which one are you choosing? In what way is this age conformal?

A lot of measurements have a normal, or Gaussian distribution, aka a “bell curve” that represent the random errors/uncertainties https://en.wikipedia.org/wiki/Normal_distribution The errors and error bars that are expressed are often the standard deviation of the measurement (but not always; this depends on the specific field), and not all errors follow this distribution (there are also systematic errors)

No, not in a scientific sense “Measurement is defined as the process of comparison of an unknown quantity with a known or standard quantity.” Also there’s got to be units, that can be expressed in SI terms https://en.wikipedia.org/wiki/Measurement see also https://en.wikipedia.org/wiki/Metrology

It’s why IMO it’s not a measurement.

I believe so. But it’s not the government doing it, and if the techbros were accessing the data there would be backlash. Like Amazon being sued over Alexa violating users’ privacy (recording and storing without knowledge or consent) https://topclassactions.com/lawsuit-settlements/privacy/amazon-alexa-class-action-alleging-privacy-violations-moves-forward/

Still needs to be quantified, though, since most is not all, so the question is how much radiation is involved?

It’s one thing for the government to monitor specific areas (public areas), and at least in the US you need a warrant to get tracking info from a cell phone. If it was discovered that this was happening without one, there would likely be an uproar.

It’s the scale of the approximation that’s relevant. Clocks today can measure and disseminate at around the tens of picoseconds level. One always tends to lead the other, from a technology standpoint - making a really precise measurement doesn’t mean a lot if you can’t tell anyone about it, i.e. the dissemination adds a significant amount of error to it (e.g. telling time to a nanosecond but your communication method is limited to a microsecond) - so there tends to be a focus on the lagging technology. During the latter half of my time at USNO there was a push to develop high-precision transfer over fiber-optic networks by labs around the world, to keep up with advances in the clocks. Prior to that it was improving satellite transfer methods using GPS signals. Time intervals/differences, if they are short enough, can be measured to even higher precision (clock vs stopwatch) It’s true. Interesting to some, sure. To those in timing/metrology, it’s more obvious. That’s a scale, though, and not a measurement. You would do a measurement with a thermometer or some other device, and that device would never be exact, nor could you be sure the value you measure is correct without calibration, which is a comparison to a standard. Yes. That’s a special category, and while you can have counting errors, you’re not really comparing it to anything.

Relative. All clock measurements are as compared to another clock. As an example, a pendulum clock ticks at some rate, but the length of the arm can vary (on purpose, or owing to e.g. temperature changes) so the only way to tell is by comparing to another clock, preferably with different/smaller sources of error. There’s no absolute measurement, no “truth” that we compare it to, no perfect clock. There’s a standard, but all measurements have errors. So nobody really knows what time it is (but some care); the time is what we decide it is - by agreement, these days. Same thing applies to length - you can’t use a ruler to tell if that ruler has expanded or contracted - or any quantity we measure

LEO especially has atmospheric drag, and there are effects from radiation pressure and gravitational anomalies. All can cause orbits to decay. I don’t have much issue with the items on the list, it’s the notion of unpopularity and that it happened just this year. What fraction of the population has to disagree for something to be deemed unpopular? For most (perhaps all) of these the opposition is comprised of a fairly small minority, and have been opposed far longer than this past year. Vaccination rates in the US, for example, have been dropping before this year, but 90% still probably qualifies as popular. The problem is that in needs to be even higher. https://www.instagram.com/p/DExj2EZRaOw/

There might be pushback against cars actually recording 360 degrees of their surroundings, by our techbro wanna-be overlords.

Yes, I think it’s quite obvious that you’ve misunderstood. I can’t fathom, for example, that one would think the existence of a tool is contrary to “doing something” for people. Why use a tool if it does nothing? Or that technology, enabled by science, is contrary. Or the notion that having the option to choose to adopt technology could be contrary. The underlying issue of the OP is one of the ability to solve problems vs the will to solve problems. Science can enhance our ability, but it’s moot if we don’t have the will, and the will (or lack thereof) has nothing to do with science’s “reach” Similar to the idiom “You can lead a horse to water, but you can't make it drink” There is no such field of study as natural science. As you say here, it is a group of sciences, a branch. The fields of study include physics, chemistry, biology and geology. One does not need to tack “science” onto these.

Not sure how this matters. Plates are on the front and/or back of cars, so the cameras tasked with this effort are pointed to mostly align with the direction of motion, not perpendicular to it. The pictures from the toll cameras I got last year were quite clear, and that was at ~100 km/hr. Getting a meter closer to the camera did not cause much blurring.

I would consider the irony of someone in one country having a discussion with people in other countries using multiple technologies derived from science arguing that science has done nothing for the people. An assertion this obtuse is farcical. It’s a subset of social science and brings to mind the adage that any discipline that has to declare that it is science, is not science.

Moderator NoteThis is too hand-wavy to meet the requirements of speculations, and if all you’ve got is repeating the same vague claims there’s no point in continuing. Closed.

Moderator NoteWe’re done discussing this with you.

There was an inquiry about why this was closed. We’re a science forum, and you need to post science. For physics, this means equations describing the phenomenon, which permits people to see if it’s supported by evidence. It’s not a WAG that you just assert multiple times.
