    Whether it be the theory of evolution or the theory of gravity, what level of acceptance and endorsement does there need to be in order to say that there exists a scientific consensus about something?

  • Why does my Kindle lose battery life when it's switched off?

    Why does my Kindle e-reader lose battery life even when I switch it off? Recently, I had about 60% battery life but switched it off and didn't use it for around a week. Upon firing it up, the battery had drained completely. 

    Although it's 5 years old, it still works well.

  • How do ISPs handle customers' data?

    Leafing through a computer magazine the other day, it mentioned that although using incognito mode in a web browser won't leave a history or cookies, it still won't prevent your ISP - among others - from knowing which sites you've visited.

    But what do ISPs do with this information? Is any employee free to dip in at any one time? Do ISPs have a system in place so that if someone accesses an illegal site they're alerted?

  • Why might a hardcover book not get released in paperback?

    More often than not, a book that is released in hardcover often appears in paperback around a year later. But I've noticed that some titles - admittedly, often comparatively obscure ones - do not get issued in a paperback format.

    Is this simply because the hardcover edition didn't sell particularly well?

  • How is it that dogs can see ghosts?

    I have read books on the paranormal and also watched paranormal TV shows, and it has been observed how dogs can suddenly become very agitated and begin barking at someone (or something) in, say, the corner of a room, when there doesn't appear to be anything there. 

    I don't know if any other animals exhibit this behaviour, but are there any parapsychological theories which seek to account for this? 

    By what means could a dog see or sense a ghost - assuming of course that such things exist?

  • Do people recommend living in an apartment or advise against it?

    I have been thinking of buying an apartment, since I feel one would suit my needs. However, most people advise against it, telling me communal living is too noisy and that when problems arise, it could prove very costly.

    What has been your experience?

  • Was this a demon or a psychic joker?

    I came across an intriguing story of the paranormal recently that was related by a third party.

    Two fairly young people were in a room and were fooling around with a tape recorder. They happened to record themselves singing a christian hymn which mentioned Jesus. They didn't notice anything unusual during the recording but, upon playing it back, part way into their singing a harsh voice could be heard over their singing. Clearly referring to Jesus, it thundered, 'HE IS WEAK BUT I AM STRONG!'

    The whole family was terrified and the third party happened to observe that the voice sounded 'old' - the implication being of course that it could be a demon. They were also puzzled as to how the voice had managed to get on to the recording, given it wasn't heard at the time.

    My question to psi researchers is: how can we know if this was really a demon, rather than just some psychic joker, and what do psi researchers have to say about the mechanism behind this phenomena, since I have read of similar occurrences in relation to electronic voice phenomena?

  • Can anyone explain how to read this nutrition table correctly?

    I have 4 slices of black pudding and I'm a little confused about how to correctly read the nutrition table on the back of the product. Please forgive my obtuseness.

    1. There is "energy kJ and "energy kcal". What is the "energy kJ" and am I right in assuming that the "energy kcal" (which is 325) is the one to go by if you're interested in counting your calorie intake?

    2. The packaging of the product says 227 g. Is this referring to the combined weight of all four slices or does it refer to each individual slice? The table shows, for example, that 11.0 g of saturated fat is contained per 100 g. So if I ate one slice would I therefore have eaten just over 22 g of saturated fat assuming that each slice is 227g?

    3. Why is there a row showing sodium and another row beneath it that says 'equivalent as salt'? I thought sodium and salt were the same things?

  • What are programming and coding and is there a difference between them?

    I am an older computer user and have noticed that programming and coding are being mentioned more and more in the news. But as someone who only uses the internet to send e-mails, shop online, download music, etc. I do not understand what these ideas are about.

    Can anyone explain simply?

  • Is China the main offender in state-sponsored hacking or is the reality more complicated?

    I was reading an article recently about a security researcher who created a series of 'honeypots' - vulnerable, important-looking computer systems - in order to tempt international hackers. Over the subsequent month there were 39 attacks from 14 different countries. More than a third of these seemed to come from China, but apparently this may not necessarily be the case since apparently hackers often use Chinese characters and code in order to hide their paymasters' real country of origin.

    So what is the truth and why use Chinese characters and code anyway in order to conceal the origin of the hacking?

  • Do these statements against man-made climate change have any value?

    "Climate change is caused by the change in position of the equinoxes of the earth in its position during its orbit around the sun and its effect and of the moon on the earth".

    "Scientists predict that we are in for a 15- to 30-year global cooling period (according to NASA, the northern ice caps are now increasing 25 per cent year on year)".

  • Why are some people of religious conviction dismissive of psi?

    As someone interested in psi - i.e. psychic, or anomalous phenomena, such as poltergeists and ESP), I am intrigued by the fact that, when I have happened to broach this subject with people of a religious disposition, they are dismissive of the subject in the same way that a skeptical votary of scientism would be.

    Has anyone else encountered this attitude? What reason might lie behind it?

    It is interesting in light of the fact that religious people themselves often believe in things - virgin births, etc. - which could be said to be equally shaky from an evidential point of view.

  • Do you agree with the following view of life and the universe?

    Although many will view the following statement as being essentially mere assertion, it has a basis in scientific fact. Thus, rather than dismiss it as mere assertion in your answers, please endeavour to refute its contentions with scientific, philosophical or theological arguments:

    Homo sapiens are an ape-descended life form, crawling around an unremarkable (at least in respect of the Solar System) planet that in turn orbits a small, unregarded star. The intelligence and consciousness of humans, though impressive, has no wider significance, for we know that Homo sapiens constitute a mere twig on the evolutionary tree. The species is a latecomer on the evolutionary scene, made possible only by the late Cretaceous mass extinction. Indeed, there is no reason to believe that the species will not one day itself be the victim of a similar conflagration - assuming it has not already by then succeeded in destroying itself - and that insects will inherit the earth. Gaia might then breathe a metaphorical sigh of relief at the ultimate failure of an interesting but dangerous biological experiment in consciousness.

    And what of this wondrous consciousness? Does it survive death? Alas, modern brain imaging technology undermines such a view; because with the advent of this we can now see how specific, localized brain injuries damage and even destroy aspects of a person's mental life. Thus, consciousness and mind are clearly dependent on the physical brain. When the brain is harmed or ceases to function altogether, the mind and the faculties are similarly affected.

    And all of the aforementioned is true because, ultimately, all reality is reducible to matter and nothing else. And this fact accounts for everything that we observe in the universe, from the most distant galaxies to the phenomenon of mind.

    It is therefore reasonable to suppose that death is the end; that religion and God are artificial, man-made constructs, made to look ridiculous when set in the context of the great, sweeping vistas of geological time that came before the revealed religions were concocted and disseminated, and during which apemen struggled ignorantly across savannahs, or paleolithic man drew images in Chauvet-like caves, desperately striving to leave a mark for posterity before dying, unheeded, alongside the cave bears and the mammoths.

    That is the reality of the human situation. It is the stark reality of this world and the universe.

  • Why does my can of deodorant bodyspray have these instructions?

    I have a can of deodorant bodyspray, and the instructions on the back of it advise me to 'hold the can 15cm from the body to spray', along with 'use in short bursts in well-ventilated places and avoid prolonged spraying'.
