Except the increasing use of cooling towers, which boils it off, which provides cooling for "free".

> The modern world may be "reliant on technology", but human minds learn concepts via observing the world while guided by other human minds. Do you think the average USA public high school grad who has a Chromebook and a GoogleDocs account and a Pearson LMS module, would be able to give a fundamentally stronger explanation of the relationships between radians, degrees, the unit circle, and the graphs of the basic trig functions, than an average student from 1990, or 1970, who used graph paper and protractors and direct instruction from someone who spent hours with them every day for a year or more?

That stuff's great to do on paper.

But I can guarantee you the light bulb goes on quicker for students I show linear regression in Desmos and have them fritter around fitting real data than those who work through it in a textbook and direct-instruction-heavy environment.

Of course, this is all besides the point: the college was having trouble admitting and enrolling students and fundraising without their technology infrastructure, not offering instruction.

> The judge in this case is right on the technical matter

The box includes a USB-C to Lightning cable.

It does not include a wall-power to USB-C adapter.

The only piece needed to charge the phone, that is not in the box, is non-proprietary.

> The only one with deserved egg on his face is you.

Don't be a dick.

> It is like how it was with toilet paper where companies in the US were asked to make some, but as soon as the shortages stopped, all the makers went back to offshore sources.

Toilet paper is overwhelmingly made close to where it is consumed. Do you think it's practical to ship long distances?

Optical image stabilization systems are all about actuating tiny masses very quickly on multiple axes. It's quite difficult to protect something like this from damage in a high vibration environment.

This is a problem everything with OIS has-- from little bitty phone cameras to large SLR rigs.

Bitcoin's market value is based on assumptions of total coin supply.

Those assumptions price in a very small risk the Satoshi hoard will be spent.

If that risk becomes bigger, it is bad for value.

At the same time, the percentage that Satoshi holds falls slightly each day, and the number of stable tractions and real float increases as adoption increases-- both of which improve the ability of Bitcoin to absorb a Satoshi shock.

That's slightly unfair, given that AT&T is the last-mile telephone carrier for an area covering 1/3rd of the US population and that cable carriers are filling the gap too.

We've got legacy stretching back to the 8008 reaching market in 1972. ARM dates to 1985, but almost all the yucky legacy was shorn off when 26 bit addressing was removed.

It was poorly phrased, but I'm pretty sure he was saying "ARM is not a -microarchitecture-, it's an ISA"

Israel is 20770 km^2.

Tokyo is about 7500 square kilometers. Even the Greater Tokyo Area is only 13500 km^2.

"It is extremely rare in our times that a simulation is not accurately simulating reality. "

Never are we using a complete model of reality--- almost never are we even using something close (and these are generally things that take days of supercomputing time to simulate a couple atom system). And almost never can we take success in a simulation in whatever domain -- CFD, electromagnetics, or even simpler mechanical codes -- as an indication that something unprecedented is achievable in reality.

Simulations are great. We can iterate more quickly with some of the iterations being virtual--- as we carefully and periodically make sure that the way we're using them are still tracking reality. They can even increase our chance of success on physical iteration 1, but there's no getting away from the need to physically build stuff to know.

> You can't use it in earth orbit without much of the radioactive exhaust falling back to the earth. If you only use it in deep space, then it is pointless because the hardest part of the journey (getting to deep space) is already behind you.

Rocket equation, anyone? Having a last stage with incredibly high impulse massively improves your capabilities. Not to mention that when we talk about many missions, it'd be nice to be able to do the long part of the journey quicker than the minimum energy ITN trajectories.

> It is extremely rare in our times that a simulation is not accurately simulating reality. Perhaps not in the same time and space resolution, but most certainly pretty accurate.

Hahaha! I can tell you've never worked in numerical methods. We have to find lots of simplifying assumptions to make any problem tractable to simulate, and those simplifying assumptions bite us all the time.

Not to mention all the ways that meshing, numerical artifacts, etc, bite us.

The sheer amount of time I've had to spend to convince myself that something is real or not real...

The former is rare in common usage.. But "kilograms of mass" and "liters of volume" are very common phrases. Perhaps redundant, though not exactly (both kg-mass and kg-force are in common usage)

Much less than 60% immunized may be necessary.

1. https://www.cdc.gov/coronaviru... About 53 million infected already. (~15%)
2. 1-1/R0 assumes uniform susceptibility and contact graphs. More detailed modelling suggested that herd immunity thresholds from natural infection (which preferentially infects the most susceptible and connected) may be like 25%. Of course, vaccination will not cluster quite the same, but it will focus on those most likely to die and people closer to the middle of the contact networks for awhile.
3. Measures short of lockdown lower Rt. I suspect a lot of us are going to be careful for quite some time.

I believe 20% vaccinated will change the game significantly, and we should be able to be there before late January. Biggest wildcard is whether people get completely reckless (undermining #3) once the vaccine is available but before they are protected.
