You'll rarely hear about colonizing Mars from real engineers, they know it's not possible.
A real engineer will only say "not possible" if the laws of physics need to be broken. Otherwise, you'll probably get a quote. It might be completely unaffordable, though.
Venus is interesting, but I have a hard time rating it 'better'. More specifically:
Health hazards: Earth: those humans evolved to; Mars: 1) Fine, abrasive electrostatic dust,
I would assume Martian dust isn't quite as problematic as Lunar dust is, since the former gets moved around more and hence has fewer sharp edges.
3) perchlorates; 4) hexavalent chromium;
You're not supposed to stick Martian soil in your mouth.
Landing difficulty: Earth: moderate (dense atmosphere, oceans to land in, compacting soil, readily available rescue); Mars: hard (reversed conditions of Earth): Venus: easy (no landing at all; your landing ellipse is "a large chunk of the planet")
Yes... but fail at landing, and you'll plummet into a 450 degree C hellhole. A rough landing on Mars might kill you, a rough landing on Venus kills you before you hit the surface.
Diversity / value of resources: Earth: moderate (that which we're used to); Mars: probably less than Earth, but not "poor";
And Mars has quite a bit of water. More than Venus, probaly.
Accessibility of resources: Earth: moderate (that which we're used to); Mars: like Earth, but hindered by mobility and the difficulty of removing overburden;
Accessibility on Mars is easier, due to the lower gravity.
It's also worth mentioning that Martian regolith is expected to cause contact burns similar to lye, due to the perchlorates and other oxidizing compounds.
Exposure to Venusian atmosphere will probably eat your skin and poison you. There are also compounds of chlorine and/or phosphorous, which tend to have interesting effects on humans...
You actually could feel an alien wind on your skin, something you could never do on Mars.
You could... short term exposure of skin to near-vaccuum should only cause reversible damage. Keep your pressure suit mostly on, though...
In general, however, a colony on our sister planet Venus - unlike a cramped pressure vessel on Mars
Pressure vessels are only "cramped" because that's the way we build them (since most of them need to ride on rockets). I would assume that different construction technologies (inflate a large balloon, then fortify it with polymers or concrete) would allow more spacious habitats.
The driver lost control and the vehicle flipped, probably impacting the ground with several of its surfaces in sequency. An actual front-end collision (car hitting obstacle with its front side, which has to absorb basically all of the energy of the impact) is different.
However, if it's a side affect of killing them, then that's actually okay.
Unfortunately, it's also legal to blind three dozen bystanders while killing the crew of a military vehicle, as long as the blinding is merely a side effect of the weapon.
A current MRi is big enough to put your body in the cavity. A small unit would be right against your scalp
The current MRI isn't just so large because it need to generate strong magnetic fields, but also because it requires magnetic fields with known and controllable gradients (to recover spatial information and to keep the MR signal within the frequency range the device is best suited to pick up).
The inverse square law isn't useful here, because the object of the MRI scan is located where field strength is mostly constant, not far enough away from the magnet that field strength drops of with the square of distance (which would also imply that field strength varies considerably and nonlinear from one point of the object to another).
It's not a matter of computational power. Sure, your cellphone has more CPU horsepower than what they used to get to the moon... but it still doesn't fly to the moon because it doesn't come with a Saturn V rocket. It's a hardware... thing.
Maybe. NMR doesn't require a gradient field for obtaining spatial information. MRI, on the other hand, does require a gradient field, unless you're content with having only one voxel in your image.
Right. So a 'display tech guru' bets that they can cram a device that a) generates magnetic fields in the single-digit tesla range and that b) basically relies on, electromagnetically speaking, hearing grass grow (and therefore requires a room with relative EM silence) and that c) for a certain range of examinations relies on stuff being injected into the patient, into a safe, wearable, customer-friendly, gadget-priced device.
My prognosis as a medical device engineer is that they'll manage maybe one of those four...
Oh, and btw, MRIs are cheap, fast and plentiful today. I've experienced a time when that wasn't the case, when there were two devices in the whole country and a month-long waiting list based on how interesting your case is. And the examination took over three hours, compared to just under 30 minutes today. If anyone claims that MRIs are too expensive today, my guess is that they're in country with a backwater health insurance system. Which could be fixed more easily than cramming a medical-grade MRI into a gadget form factor.
I had a "technology of the future"-type book that suggested planes being powered with lasers from orbit (which doesn't require all the conversions that an 'electricity from orbital power plant' system needs since the plane would consume most power in the form of heat).
Intriguing.
I'm sure nothing can go wrong when aiming a couple dozen megawatts of laser power at a moving target.
Just try holding your breath for ten minutes, and you'll realize that your supposed free will doesn't even have full control over your voluntary muscles.
Isn't it conflictive to believe in an all-knowing and all-powerful deity while at the same believing in freedom of choice?
No. "All-powerful" implies being able to chose not to know something (for now. Okay, this is a bit weird, since "all-powerful" also implies existing outside time and, consequently, outside of causality, which requires time), and being able to chose to leave something to completely and perfectly random chance.
So the brain isn't a constantly changing network of neurochemical pathways and turns to pudding the instant of death?
It's actually the other way round. Once it has been established that the constantly changing network of neurochemical pathways has irrevocably turned into pudding, brain death is declared.
Irrelevant for the definition of "brain death". It means that the brain, as an organ, is currently nonfunctional and there is no prognosis of it returning to a functional state at any point in the future.
If you disassemble a brain into its component cells and keep each and every single cell alive in the process, the result is still brain death.
What happens if you legitimately can't decrypt a drive.
Claim that you used OTP encryption, ask for a copy of the encrypted data, generate a key that will decrypt the encrypted data, verifiably and reproducibly, to any plaintext you chose.
I assume that would take either a compromised driver, or a compromised peripheral.
Neither, actually. Unless you count a sniffer on the USB lines as "compromised peripheral". (hm, yes, hiding the sniffer inside the device/inside its USB connector is probably the most inconspicuous method).
"How does the peripheral transmit said keystrokes/mouse clicks to the "command and control" server?"
You don't have to transmit anything if you're capable of retrieving the device. You can pack a few GB worth of flash memory even into tiny devices; and even a fraction of a GB stores days worth of keystrokes and mouse movements.

Disco balls are not required. At this power level, even diffuse reflections of the laser are dangerous to the eye.
Oh wait, this is the military.

If medicine could treat any condition (including anything age-related), then the only thing people would die from are medical errors.

"Zombie" is neither a legal nor a scientific term. I think the OP is looking for "undeceased".
