first concept that to to be make clear, is some measurables are frame dependent concepts:
e.g. mass/energy, time, momentum , length
different reference frame will measure a different value. they are all valid from their perspective.

photon or anything that move at [speed of light] do not have a rest frame, aka u cant comove with it in some platform that its speed is zero relative to u.

since there is no photon reference frame. rest mass of a photon is UNDEFINED. photon does however have a relativistic mass when measure from a any inertial frame. as dictated by E=MC^2

there are many species of mosquitos. you only need to eradicate the human biting ones (e.g. infamous Aedes aegypti). most mosquitoes don't target human. spider, bat can eat those instead.

-lead in petrol (TEL)
-lead in ammo (primer, bullet)
-lead in water (lead solder, iron pipes)
-neurotoxins in tobacco (lead and friends, nicotine itself)

are we surprised that younger cohorts are somewhat neurologically healthier because above are being phased out?

The problem is easier to solve than you think.
The AI attacker side knows where his friendly force are in the 1st place. Just designate kill-zone / no-fire-zone, and instruct friendly force to never enter the kill zone. Everything that moves in kill-zone is a "valid military target" for lulz.
Alternatively one can use various electronic friend-or-foe identification, but this will leads to communication complexities and spoofing issue.

"What you're referring to is a battery pack, not a battery. A battery is a single cell."

no. battery is multiple cells connected together electrically to work in unison. another example is artillery battery is multiple guns work under single command and fired in unison.

what individual self contained sub units in a electrical battery is called cells, short for electrochemical cell.

It's worse than that. Printers. Start menu. File search. Updates. used to work fine in the win2k->win7 period. Somehow MS is able to either break the functionality, or replace it with unusable newer version.
MS should just leaves windows UI/basic tools at win2k/win7 level, and add new hardware support/software framework/security update under the hood. That's what most users (both home and office) actually wants.

dafaq u mean with those driver madness?
brother laser printer are just generic network printer.
On linux IPP/cups with PostScript/PCL works just fine.
On windows you just use the brother universal PostScript/PCL driver. they are barebone driver and no crapware included. heck it even supports winxp.

I don't think bacteria is better in DNA repair than us eukaryote.
It is better in "surviving" radiation in the sense that SOME individual cells remains viable, keep dividing and maintain the colony. Radiation damage is intrinsically random. Some DNA damage are repairable because of luck, those individual cells "survives". Unlucky bacterium with unrepairable damage just dies. As long as some individual remains viable the colony "survives" the radiation.

Multicellur organism like us need functioning organ/system to work in concord. If too much cells died in a particular organ, the organ fails and the whole organism dies. EVEN MAJORITY OF THE CELLS IN THE BODY ARE ACTUALLY INTACT.

Medical personnel still use pagers for several important reasons:

Reliability: Pagers use high-frequency radio signals, which are more reliable in hospital environments where cell phone signals can be weak or blocked by thick walls.
Coverage: Pagers have a broader coverage area and can work in places where cell phones might not, such as basements or remote locations.
Battery Life: Pagers have a much longer battery life compared to smartphones, often lasting weeks on a single charge.
Emergency Situations: During emergencies, cell networks can become overloaded. Pagers, however, can still function effectively, ensuring critical messages get through.
Security: Pagers are less susceptible to hacking and data breaches compared to smartphones, making them a safer option for transmitting sensitive information.
These factors make pagers a practical and dependable tool for medical professionals, despite the availability of more modern technology.

Most likely dies with higher failed core counts during test are e-fuse disabled to make chinese-4090.
If demand is high even healthier dies can be artificially e-fused to the 14592 limit.
No separate production line is needed, nor could the disabled cores be reactivated by consumers afterwards.

1) glacier melts will end up in the ocean. Seawater is not potable. 2) glacier act as storage/buffer of fresh water, which are slowly released. Without these buffer, most snow/rain will be rapidly flush down into the ocean. You can flooding in the rain season, and dry up river in the dry season.

In short yes.
Long version.
A perfect ticking clock has only 1 oscillation frequency, thus each 'tick' take exactly the same time.
An imperfect clock(real world) clock always has fundamental freq + various overtones, thus there is uncertainty btw each tick.
Single oscillation frequency implies the clock ticks from -infinity to +infinity => forever. Even with limited operating power, it would take infinity energy to operate.
Since irl machines can't work with infinite energy, single oscillation frequency is impossible, thus the accuracy of the clock is fundamentally limited.

....just by increasing frequency to x-ray range. You get wider bandwidth as a nice side effect too. *ducks behind lead shield*

Most proposed implementation "trapped" by using delay element; i.e. kilometers long loop of fiber optics etc.
Incoming photon with correct expected arrival time are matched with the corresponding reference photon in the delay pipeline. If the quantum value are complementary, the photon is registered as a data point. Any decoherent return photon are treated the same as bckgnd noise(discarded).
You don't need a bright return of complimentary photons. With most noise eliminated, an image can be built up gradually with individual matching photons anyways.

Background noise is as easy to filtered out as jam signal.
Defining feature of stealth aircraft is it reflects little radio wave towards the direction of originating radar. Whatever photon that get reflected back are greatly overwhelmed by background noise. Stealth aircraft thus escape detection.
With quantum radar, the radar *KNOWS* which photon comes from the station, by correlating with the reference photon. Bckgnd noise photon are probabilistically unlikely to correctly complement the reference photon. It is trivial to filter out the bckgnd noise in this scheme. With a noise floor so low, whatever low power return will stick out.
This super high S/N ratio allows another interesting feature of quantum radar: the source radar can be very dim, below bckgnd noise level. To the stealth aircraft, it would not know it has been scanned because the scanning beam is mask by bckgnd.
