I would think whatever normal temperature range you consume anything will be more or less body temperature pretty quickly - in the order of minutes - so it's effect on digestion would be negligible.

The UK NHS says "The term 'processed food' applies to any food that has been altered from its natural state in some way, either for safety reasons or convenience." I think the concerns mainly pertain to restricting the regular consumption of convenience foods which may contain less than desirable levels of salt, sugar, fats, and preservatives etc.

You can use Snipping Tool in W7, or other third-party app, after opening the doc and save it as an image file. You could use PRT SCN as well, paste it into an image editor then crop it. Click or right-click on the image to save it if you want to use this.

Imagine you are sitting on a rock in the empty vacuum of space with absolutely nothing around you. You see a rock in the distance getting bigger with time. Are you moving towards the rock or is the rock moving towards you? Because you feel stationary – but you may actually be moving uniformly - it seems the rock is moving towards you. You will have the same experience if you sat on the other rock looking where you are now. This is why velocity is always relative to something because you have to choose what your reference point is.

You can 'walk' compasses on a map hence together (com) + step (pass) = step together. Just my guess

You know what we are going to say.

"Space is big. Really big. You just won’t believe how vastly hugely mindbogglingly big it is. I mean you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space." - D. Adams What you are seeing, when you observe it, is photons that are interacting for the first time with your instrument since they were emitted... the rest just carry on their merry way to the next observer or interaction. It happened all over and they are travelling all over. Not much different to the expansion happening all over.

Found a forum conversation with someone that seems to know who's a gas appliance diagnostics technician.

I read on a supplier's site to ignore the last dial because it is for testing. Perhaps it is isolated mechanically to give an independent measure. I'm only guessing here but the general theme of my enquiries is that it should be ignored from a consumer perspective. No harm in wanting to know why though.

It's just for testing.

Right. Cheers.

I'm just a novice in science, so, does it need to be in a journal to show that it has been peer-reviewed? Your reference is behind a pay-wall unfortunately. I can't find an open access version.

Interesting. Still not digital yet then. Does ambient temperature affect the accuracy of flow meters in terms of the amount of gas actually delivered through changes in pressure caused by it or does the pumping station compensate for this?

Thanks

It seems to me the dial is for showing a more sensitive real-time indication of gas usage - one revolution equals 1 cu.ft Here's a Parkinson: Here's British Gas one: Seems to be a standard indication

It is when one introduces metaphysics and mysticism as apparent components of it. I think, to have a sound footing in philosophy, one must know the mechanics of human consciousness and that means being fluent in cognitive neuroscience or biopsychology. By understanding this subject one can get a grip on the limits of perception of the world around us. If we don't know how our brain pieces the world together how can we hope to extrapolate the external reality in a scientific way? Without this prior knowledge of objectively-observed cognitive functioning philosophy will forever remain founded on sand. Dennet is at least, in my opinion, on the right track in his field of studies by including cognitive science as part of them.

There are a couple of guys that think the core is off-centred to explain the east-west difference... but not due to gravitational effects. I can't find the relevant part now about it not being caused by gravity. Abstract: In a first approximation, the Earth's interior has an isotropic structure with a spherical symmetry. Over the last decades the geophysical observations have revealed, at different spatial scales, the existence of several perturbations from this basic structure. In this paper we discuss the hemispheric perturbations induced to this basic structure if the inner core is displaced from the center of mass of the Earth. Using numerical simulations of the observed hemispheric asymmetry of the seismic waves traveling through the upper inner core, with faster arrival times and higher attenuation in the Eastern Hemisphere, we estimate that the present position of the inner core is shifted by tens of kilometers from the Earth's center eastward in the equatorial plane. If the only forces acting on the inner core were the gravitational forces, then its equilibrium position would be at the Earth's center and the estimated displacement would not be possible. We conjecture that, due to interactions with the flow and the magnetic field inside the outer core, the inner core is in a permanent chaotic motion. To support this hypothesis we analyze more than ten different geophysical phenomena consistent with an inner core motion dominated by time scales from hundreds to thousands of years. Geophysical implications of a decentered inner core - arxiv Abstract In a first approximation the Earth's interior has an isotropic structure with a spherical symmetry. Over the last decades the geophysical observations have revealed, at different spatial scales, the existence of several perturbations from this basic structure. Some of them are situated in the neighborhood of the inner core boundary (ICB). One of the best documented perturbations is the asymmetry at the top of the inner core (ATIC) characterized by faster seismic wave velocity in the eastern hemisphere than in the western hemisphere. All existing explanations are based on a hemispheric variation of the material properties near ICB inside the inner core. Using numerical simulations of the seismic ray propagation, we show that the ATIC can be explained as well by the displacement of the inner core towards east in the equatorial plane tens of kilometers from the Earth's center, without modifying the spherical symmetry in the upper inner core. The hypothesis of a displaced inner core is also sustained by other observed hemispheric asymmetries at the top of the inner core and at the bottom of the outer core. A displaced inner core would have major implications for many mechanical, thermal, and magnetic phenomena in the Earth's interior. Seismic hemispheric asymmetry induced by Earth's inner core decentering - arxiv Edit: See bolded in first abstract that gravitational effects are not suggested to cause decentering.

I just happened to look at some of his posts last night and thought to myself he is one of the clearest explainers I've ever seen anywhere. I've been coming here virtually everyday since 2009 and developed a real liking for physics because of the enthusiasm, patience and generosity shown here by the qualified members and dedicated enthusiasts. I also find the eclectic demographic of the membership constantly refreshing.

Einstein was apparently about two years advanced, relative to his peers, in his education as a teenager. The idea that he was not so bright came because the education administrators reversed the grading system after he had done his thus making him look not so bright.

From iNow's link: Just do it.

Put some water in an open jug and cover it with something porous to let the chlorine gases out and keep flies off. leave it a few hours.

Dark Energy is the phenomenon hypothesised to be driving the accelerated expansion. http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/

I don't think scientists like infinities, it's just what the models tell them and those models have probably gone beyond the limit of their application.

The thing is in science certain words mean certain things. This is so that when certain words are used they are understood in a certain way. It ensures everyone is visualising the same things otherwise it's like a band with all the members playing different tunes at the same time.
