7 was nice but 10 is much better and is here to stay; it will only evolve gradually now. There's a bit of a learning curve with changing certain habits and expectations but I find 10 very automatic and intuitive to use. You can bring up everything from the Search box and there are many apps already built in. The email client is awesome very easy to use for example. 10 is a natural evolution of 7 so I would point you to 10, without a doubt.

If heavy water ice starts at 3.81oC and it is in ordinary water at a temp of 0oC why does the heavy ice dissolve but ordinary ice won't?

I use this and you can get it for mobiles as well. It's very good and has made a noticeable difference to eye comfort, especially at night. Excess blue light balance in the wrong part of the day can mess up your circadian rythmn (sleep/alert pattern) as well as strain your eyes in the absence of natural ambient light. I think at night time your domestic lighting will be much warmer in balance compared to an uncompensated device screen and looking away and into the screen continually through the evening probably forces your eyes to keep adapting chromatically, leading to strain as well as confusing your brain as to when it should rest or be alert. https://justgetflux.com/

http://mathscinotes.com/2014/02/heavy-water-ice-cubes-do-not-float/ Density of H2O ice: 0.92g/cm3 Density of H2O liquid: 1.00g/cm3 Density of D2O ice: 1.02g/cm3

It is possible to change the colour temperature of PC screens etc

Mark Twain is one of my favourite wits, along with Oscar Wilde.

Ok, thanks.

If one pumped music in the form of pressurised gas perturbations emitted from speaker-shaped outlets, at an astronaut floating in space in front of them, would he hear the music through his helmet?

What is sleep but a little slice of death. (apologies to E.A. Poe)

Only to another person, not yourself.

By both methods, it's still photons entering your eyes. The obvious thing to do is to turn down the intensity to the same level and contrast as a Kindle-type device.

Depends on your society. You are using your own cultural value system to judge, by the sound of it, by asking that question. Note this, and I said this myself, in other words:

if a judicial system doesn't have the consent and respect of of the majority of it's populace it won't work. Whilst a society has guns for the purposes of 'self-defence', I think the death penalty needs to remain. If the individual has the right to take a life (in the name of self-defence; innocents get massascred as a byproduct/ then the system should have at least the same power to defend societal stability and express outrage, as an option. The tacit contract between the state and the its citizens is that it will apply mutually consensual justice; whatever that maybe. Democracy is the expression of the majority; call it 'mob justice' but that's whatever holds a society's population together in some sort of social harmony.

The new Guthenberg Kindle! The pressing of the bible got everybody reading and look where we are now a few hundred years later. I had to throw that one in

It was answered by the not-so- knowledgeable-but-correct and the very knowledgeable/professional on the first page; take your pick. The subsequent discussion has been about a hypothetical scenario you painted but the original core answer remains even in that but some don't understand it.

Concisely and eloquently put. +1

I think it depends on the moral code of a given society if it's ethical or not. I think it is too simplistic to judge from one culture's moral code upon anothers; the general consensus/consent of a participating society's population matters.

It's been answered and it is "No".

Indeed.

1. Both experience a 100km/h collision; measured from either frame 2.Car and wall experience a 50km/h collision; measured from either frame 3. Both cars experience a 50km/h collision; measured from either frame. It follows that 2 and 3 will experience the same degree of collision. Whichever frame you measure from you are the stationary observer.. what that means is, in scenario 1, for example, the car opposite the observer vehicle is measured travelling at the combined velocities of the two vehicles; velocities are additive in ron-relativistic physics

Sometimes, ideas come up to solve a problem before they are actually confirmed. Mental masturbation can be very useful and insightful when done right. It's how many models are made. .

if you read this link; http://www.gardensalive.com/product/rock-your-garden-with-rock-dust/you_bet_your_garden You need it to be mixed with soil that has a lot of microbes. It might benefit the microbes that benefits the plants. The idea does make sense but you've just got to make sure the conditions and materials are right to allow mineral availability. It mentions basalt dust as good and I've read granite dust is as well. Note the particle size it recommends as well; that wants to be your maximum.

I would think the mineral content is important, or else, what's the point?

This from Clinton comes across as egotistical narcissism; I think the next US election is definitely a case of picking the lesser of the evils. I don't trust either of them.
