I read a while back that a surgeon accidentally got cancer from one of his surgical patients:
So, it appears that cancer can move between hosts in a mechanical fashion.
I found a nastier one a while back: guy has tapeworm, tapeworm has cancer, tapeworm spreads its cancer throughout the guy's body as it wriggles around.
Here's the story. One of the interesting things was that the tapeworm tumors had differently-sized cells, so they were easy to differentiate from the host's cells. Now, that's not exactly cancer being transmitted, insofar as it wasn't his cells that were turning cancerous, but they were growing/multiplying and helped cause his death. It's like being infected with some other animal's cancer.
Among epistemologists the near-consensus is that belief is one of the necessary ingredients of knowledge.
Cite? I know lots of things I don't believe in. For example, I have quite a lot of knowledge about how magic works in various fictional systems. I find it much more likely that you're mischaracterizing the belief/knowledge of epistemologists than that they're really that stupid.
I feel the same way you do, but:
"There are three components to the traditional (“tripartite”) analysis of knowledge. According to this analysis, justified, true belief is necessary and sufficient for knowledge.
The Tripartite Analysis of Knowledge:
S knows that p iff
p is true;
S believes that p;
S is justified in believing that p.
The tripartite analysis of knowledge is often abbreviated as the “JTB” analysis, for “justified true belief”."
certainly reinforces at least a classical view that epidemiology claims belief is necessary for knowledge (with the proviso that there are modern theories of knowledge that disagree.)
The kicker seems to be in the use of the word 'justified', which I think I'd characterize as a weasel word on Wikipedia.
AI 'Could Leave Half Of World Unemployed'?
In 1790, more than 90% of the population in the US was involved in agriculture.
Then came 150 years of relentless automation and today, 2% of the population is engaged in agriculture while today there is 5% unemployment and less than 2% unemployment among the college educated.
In the early 1900s, the automobile industry started putting horse-drawn carriages out of business, destroying 99% of that industry, while today there is 5% unemployment and less than 2% unemployment among the college educated.
In the 1980s, the adoption of email enabled corporate America to "flatten" organizations and lay off a great portion of middle management, while today there is 5% unemployment and less than 2% unemployment among the college educated.
Now, some well meaning idiot who has never read a book on capitalist economics wants to scare us about robots causing mass unemployment.
Today, the US employs, more than 2.5 million people in Arts, Entertainment, and Recreation," and 6.2 million people employed as scientists and engineers. We still have not conquered cancer, heart disease, genetic defect, spinal injuries, or figured out how to cost-effectively deal with global warming.
Only by automating more jobs can we free more people to pursue science, medicine, and engineering.
Bring on the robots!
For example, the average person has approximately 1 testicle.
Whenever people trot out the tired statistic that 70% (or whatever) of drivers believe they're better than the average driver, to mock the idea of how well people rate their own abilities, I trot out the statistic that 99.9% of humans have more than the average number of eyes. We assume gassian distributions with no idea if that's actually representative of the results.
With that said, at least the air force example is a case of misunderstanding of how averages concatenate, which is a slightly more complicated poor understanding of statistics. (It doesn't take long to calculate 0.3^10 and realize that it's an extremely small number, but that's not intuitive if you haven't taken statistics classes, or, in my case, lots of chemistry classes: when you have a complex synthesis that has seven steps, each with 80% yield, you realize you're going to need kilograms of starting material to even measure your final product.)
I'm going to argue with the OP. Most retrofit cnc kits won't give you 0.002" repeatability because the lead screws are too sloppy. LEGO bricks are built to 0.0002". A Tormach 440 cnc, cost $5K, with ballscrews rather than leadscrews, still quotes positional accuracy at 0.0013". Prices rise quickly from there. The Haas minimill, at $34K, appears to claim positional accuracy of 0.0005", although it's not obvious that its repeatability is that high.
Your best bet would most likely be a small SLA printer. Like the a Formlabs or a Autodesk Amber.
We tried printing LEGO form-factor bricks with a (now older) Stratasys mid-range SLA. The results were marginal for plates, ie topside-only, and flat-out unacceptable for the bottoms of blocks. Blocks that were correctly dimensioned to snap onto a lower block, and thin enough to snap in beside another block, broke during use. We had to make fat blocks -- increase wall thickness -- that couldn't nest in beside other blocks to get ones durable enough to survive a dozen attach cycles.
If you could reduce that 2700 pounds down to 2200 pounds, with 200 horsepower, that could be both fast _and_ nice-handling.
They could also slap 300 horsepower in there without any trouble, there are a number of V6s that would do the job in that small space.
Based on my experience, of having put a lightweight-for-a-V8 buick 215 in a little british car, and then replaced that with a 1.3 liter suzuki that weighs less than 100kg, I vastly prefer every bit of the handling characteristics of the smaller, lower-power engine. The v8 was much better at drag racing, but the i4 in the same car with the same tires completely obliterates the v8 in initial off-the-light acceleration, turning, braking, and generally everything that car does when it's not on a dragstrip. The DeLorean weighs 70% more than my car, so it won't be as marked a change, but I've become a big advocate for removing weight rather than adding power.
They're talking about putting in an engine w/ 300-400 hp, which doesn't sound like a huge number, but the original car weighed 2700 lb. If they're close to that weight with a decent transmission it will be damn fast.
I can see a few problems though. The original frame/engine mount only had to deal w/ 130 hp, so probably some modifications needed there. The weight distribution was 35/65 front/rear. With a presumably heavier engine/transmission and anything else needed back there that ratio could get problematic.
A lot of people seem comfortable driving fairly high-performance older cars with serious rear end weight imbalance, like corvairs, which had almost the same weight distribution. The PRV V6 wasn't very lightweight. If they were willing to continue with Colin Chapman's original design philosophy and sacrifice some horsepower for a lot of weight reduction, there are 125 horsepower engines that weigh under 100kg out there these days. If you could reduce that 2700 pounds down to 2200 pounds, with 200 horsepower, that could be both fast _and_ nice-handling.
By the way, the fine article refers to this change in regulations which allows low-volume manufacturers to produce classics without things like airbags or OBDII. That's interesting because a ton of cars vanished from the landscape not from lack of consumer demand but because the design was unable to be economically and aesthetically updated to meet new regulations. The Jaguar XKE is a perfect example. Again, cars using modern drivetrains, fitted in classic bodyshells, would be a neat mix of beauty and durability. As anyone who drives an old car will tell you, driving with a full toolbox in the back, out of necessity, can be a headache.
The engine and transmission were underwhelming in the original, and modern engines with significantly higher power, and lower weight, are ubiquitous. If it had decent engineering -- as in, if they are using a modern differential and wheel bearings -- the stainless steel body could make for a car that lasts for decades. However, man, the dash design was seriously dated and would need a ton of updating to look even modern, much less futuristic.
In other words, I'm dubious about the commercial viability of that car's design with only a new engine. A new engine, drivetrain, interior, and electronics, would make an interesting car... but that's not quite the same as "only the engine [will be changed]".
If I buy a car from the dealership for $50,000 and then try to sell it 10 minutes later it's now worth $25,000 at most.
If I buy a used vehicle from someone for $15,000 and try to sell it 10 minutes later it's still worth about $15,000.
Why take the hit?
Also a car that is worn out still has a pretty poor resale value even if it is just a year old.
Maybe it's that I'm coming at this from a different usage pattern than yours, but new cars make a lot of sense to me. I bought a new Subaru in 2001. I put 230,000 miles on it, and when I got rid of it, the head gaskets were leaking, two CV joints were failing, the center differential limited slip clutch pack was no longer working, the shocks were shot, and it was way overdue for new timing belts, the cumulative cost of which far exceeded the car's value, so it went off to a junkyard. The previous Subaru I had was totaled. Before that I had a Nissan, that was totaled. I've never sold a car to anything but a junkyard for scrap value, so while the depreciation on a new car is high, it's also meaningless to me.
In contrast, when the last Soob went off to the junkyard, I bought a used Subaru, and over the last three years I've had to replace the transmission, two CV joints, the shocks, and am about to have to replace the u-joint/cv joint (I haven't taken it out yet so I don't know which) that goes to the rear wheels, none of which I had to do on the new car, because it was new. While it was busy depreciating, I was busy driving it rather than fixing it.
For my use case, new cars are significantly cheaper, have higher availability, and I don't end up spending weekends in the snow replacing CV joints.
I somehow doubt that there is an actual "dial" on the device, be it digital or analog. I feel like that feature is referring to a field serviceable warhead that can be swapped out; as opposed to one that is fixed in place from the OEM. Although your idea is not without merit, the US has experimented using nuclear fallout as an area denial weapon in the past. That just doesn't sound like the kind of thing that they can sell to Obama.
Note that I don't know what I'm talking about, but my understanding is that dial-a-yield refers to the use of cores that are injected with lithium deuteride, to fusion-boost a fission reaction, and the dial is how much lithium deuteride is injected (and how much is left in the supply, which is carried along with the bomb.) In that sense, it is pretty much a dial because it's the same warhead hardware regardless of yield, with a software or hardware change that determines the explosive yield.
Patents are so inconvenient: limited lifetime, you have to publish how you're doing what you're doing. Much easier to just turn trade secrets into secret, infinite-life patents, now with government protection and a nice threat for any small companies that dare to try to compete with you.
