Why would they pray to God for a new vaccine? If you got sick, clearly you were an evil sinner whom God felt needed to be punished for your unholy ways.
I honestly don't understand why public schools can't teach religion. With so much of the world's cultures and politics deriving themselves from various religious ideologies, that seems like a pretty damned important topic for any well educated individual to be versed in. Start holding a religion class as a history/social science, and explore the groundwork of all the major world religions. That seems like it would be the perfect place for these creationism "controversies" to be hashed out.
Matter exists as discrete particles. Oh wait, matter exists as a continuous wave. Oh wait, matter presents itself as a probability field that prevents us from ever truly knowing its properties. Shit!
Most laymen viewing modern particle physics from a distance would see some pretty spooky action.
Come now, the holocaust never happened. Sure, millions of Jewish may have been captured and inducted into labor and prison camps by the Nazis during WWII. Sure, millions died in those camps, often times murdered and disposed of in open pit fires or incinerated in large furnaces, not necessarily in that order. However they weren't being ritualistically sacrificed to any deity as part of some perverse exploration into the occult. This was just plain and simple mass genocide. Calling it a holocaust is a misnomer.
Learning to support the points through logical debate is still a valuable skill. You cannot have a logical debate with someone who is operating on belief rather than logic and reason. Your opponent's conclusion was already decided before they started to analyze evidence, and thus the winning criteria of proving them wrong can never be achieved. If you can't win, there's no point in bothering to try. Attack the problem from another route, isolating them and marginalizing them in society, so their beliefs cannot cause the rest of us grief.
Name a single set of global average temperature and global average CO2 observations, past, present or future
If you have a set of future global average temperature and CO2 observations, I think we can nip this whole global warming thing in the bud right here and now.
Observation is not fact. Observation is only the recorded evidence based off the limits of our sampling mechanisms. Better sampling mechanisms could come along with finer granularity and show previous observation was completely missing the important bits. Some unknown or unaccounted for phenomenon could be affecting the instrumentation causing it to give bad measurements. There is no fact in science, only the current data and our interpretation of it. When you start throwing around words like fact, you are no better than those who wish to discredit science for their own gains by misrepresenting the meaning of theory.
No. Evolution is still a theory. There is no fact in science. There is observation, and interpretation, and nothing more. While there is experimental evidence showing genetic variation and adaptation between different related species, long term artificial selection in domesticated breeding programs, and laboratory testing showing short term selection and adaptation in bacteria, there is nothing disproving the existence of omniscient, omnipotent being of rehydrated processed grain, playing a practical joke on us five billion years in the making, to cause us to think this is all a natural process.
Evolution is our best interpretation of the available evidence, using Natural Selection as its adaptive vector. Science cannot disprove the presence of a creator. There is exactly zero evidence one exists, but then there is exactly zero evidence one doesn't exist. No scientist will ever say there is no god, as absence of evidence is not evidence of absence. The problem with creationists, intelligent designists, and their whole lot is that they take their own theory on blind faith. They already know they are correct, so there is no need to prove they are correct. All they have to do is prove that evolution is incorrect, and they're automatically all that's left. It never even comes into their thought process that they could be wrong and Evolution is right, or both they and Evolution are wrong, and some completely foreign third concept is what is actually going on.
My regional ISP gives me up to six dynamically allocated addresses, and it would take me all of about 30 seconds to go into my firewall configuration, point my desktop out through another external address, and moderate myself up.
No. There are no mechanical components, there are no rubbing parts. You pull vacuum on the unit so there is negligible air friction. You levitate using permanent dipole magnets, meaning there are no bearings to fail. You use a modest amount of YCBO or some other high temperature superconductor for flux pinning and stabilization of the rotor. That leaves your vacuum pump and your LN2 chiller. You make them multiply redundant, and hot-swappable. If one fails, it throws up a warning, and notifies you to get it replaced.
Costs are still a bit high for flywheels for the specific application that article was describing. They are UPS units, designed to provide high power output on the order of hundreds of kW, for long enough duration that you can start up your backup generators. Something designed for residential needs, and produced in the large volume that residential use would allow, could be made much cheaper. You also need to factor into the cost of replacement, for which a magnetically levitated flywheel will likely outlive its original owner with zero maintenance. The best battery designs typically only run for a couple thousand cycles, and would need to be replaced in 10-15 years.
Yes. Don't bother messing around with lithium. We should build all of our energy storage out of inefficient electrolysis and large amounts of platinum.
Those storage costs are going to need to be paid anyway should we ever want to improve our power grid. The US currently has around 1TW of installed generation capacity, but we only average about half that. Pervasive storage would mean we could rely on more efficient but slower to respond base load plants. Our long distance transmission infrastructure would not need to carry as much instantaneous power, meaning these is immediately significant overcapacity and redundancy in the system. Areas isolated by downed lines could operate in a splinter mode, and slewed into sync with the rest of the grid when repaired and re-attached. Excess power could be shunted into storage, rather than cause equipment to disconnect in self-protection, significantly reducing the risk of cascading failures.
Is that for the typical high current applications such as short term backup power before you engage generators, or for a more modest current unit better suited for residential operation? Everything I've seen commercially available is on the order of a couple hundred kW or better. Way overkill for anything you might need in a home.
In a sense, yes. These flywheels are hollow to maximize the rotational inertia (and storage) for a given amount of mass. You design the rotor with an integral "squirrel cage" built into this hollow cavity, and put a stator on the central shaft. If you want to add or remove energy, the stator sets up a rotating magnetic field that induces a complementary field in the rotor, and energy is transferred depending on the slip rate between the two. If you want to idle, you remove the frequency driver on the stator, internal resistance on the wires rapidly damps out any residual current and magnetic field, eliminating any potential eddy current losses and the need for mechanical actuation of any coils or magnets.
Considering you're talking about achieving orbital velocities in just a few miles up the side of mountain, it may as well be a railgun with the kind of acceleration you're going to have. Rough estimate puts a 5km diagonal launch ramp at 2000Gs, and you're still going to need a decent orbital insertion motor once you get out of the atmosphere.
Mirrors are not perfect reflectors. Pump enough heat into a sufficiently small area, and you will destroy the mirror and breach the protection. Mirrors are only good over a certain frequency range. Use a free electron laser such that you can modulate the frequency to whatever you please, and you can choose one that will heat the mirror will heat up much faster. The higher reflectivity your mirror, the more fragile it tends to be. Use a relativistic particle beam instead, and the mirror is useless.
The problem is exactly the same as the one Intel enjoyed with Hyperthreading, but not something that could be fixed with a simple "hotfix".
Hyperthreading allowed for two simultaneous executions through a single unit, but didn't have a sufficiently beefy prefetch/BP/dispatcher to drive that efficiently. The overhead often made the CPUs run slower with Hyperthreading enabled than disabled. Bulldozer made the same mistake. They doubled the number of integer units, but only made modest improvements to the frontend hardware. As a result, they can't keep both of those significantly lengthened pipelines filled.
Now there are some improvements to be made. Under lighter workloads, you can spread your threads evenly across all your modules, rather than all your integer units, allowing access to more dispatch hardware. You can make changes to ensure threads from a single application land on the same module to improve cache coherency, preventing them from having to wait on data from another modules. However, none of these are going to be a "magical fix", and will only offer modest improvements over the current performance.
A personal surveillance drone isn't of much use if you personally have to control it. Is he developing some sort of automation for it, or is it really nothing more than an RC aircraft with a camera?
