  1. I found this (untested) source that suggests that there have been 118 USA mass shootings in the previous 38 years which averages at about one a quarter. It also suggests that just over 50% are perpetrated by whites. Or, alternatively, just under 50% by non-whites: SHM
  2. This is by no means a certainty, so may I suggest if humans...
  3. My Latin Master at school was a stickler for prescriptive grammar and "proper" syntax in both spoken and written English such as the correct use of fewer/less, rather/instead, which/that, and of course that damned split infinite. On the other hand, my English Master was quite hip and laissez faire with a "if it sounds right, it is right" attitude and that language should be allowed to evolve without being stifled by out-dated traditions. Whichever approach one takes, English has a peculiar set of inconsistent rules that I image are quite difficult for a non-native speaker to grasp; not to mention frustrating! As for using belief as a noun I'd Keep It Simple Sir, use basic determiners and go with this: The less there is then the less there is to confuse.
  4. Yanchinin looks like typo as the title of the pdf posted by @SergUpstart includes Janchilin V.L. Does this help..? https://www.google.co.uk/url?sa=t&source=web&rct=j&url=http://www.pirt.info/files/documents/proceedings_PIRT_2015.pdf&ved=2ahUKEwi7_aWduv7pAhVxsHEKHRFdBcoQFjAAegQIARAB&usg=AOvVaw3v6BAYpo9xPt503b_96TEq The name Janchilin only appears twice, most notably as Reference 21,on page 298. It may be worth a look...?
  5. There must be a genetic disposition to being bitten. Neither I nor my close family get bit - ever - but most extended family members do; some quite severly. Even when I was stationed Central America living for extended periods in the jungle I didn't get bit, unlike my poor team mates. Maybe I don't taste nice or it could be down to having some form of evolutionary immunity due to my white-African heritage. Anyhoo, military personnel the world over swear by a spray called Avon Skin So Soft. It's cheap and apparently very effective.
  6. I've just read this... ...and I was wondering if a gas can be "super cooled" and remain as a gas instead of condensing to a liquid (some go straight to a solid IIRC) can the same be true for plasma? Hopefully they might get some more interesting results with their research in to quantum level collisions, gravitational waves and the equivalency principle. I guess working in microgravity will be the next big milestone in our understanding of these things. Interesting times ahead. https://www.newscientist.com/article/mg24632862-300-exotic-fifth-state-of-matter-made-on-the-international-space-station/
  7. Looking from the outside, the USA seems to be somewhat vocal and have quite polorised views so I was pondering what the future may hold following the heightened awareness of slavery and positivity created by the BLM movement. Although the current focus is mainly on the activities of the USA, UK and some other Western countries starting around the 17th century, the abuse of slavery extends back to at least Classical times and most, if not every, nation's history is tainted by it in one way or another. So I think it is a legitimate question to ask what - or more properly - who next? Or, indeed, will there be a "next"?
  8. Interesting conversation, thanks folks. Has there been any noticeable hostility in the U.S. towards earlier North American history? Such as: the Founding Fathers; British, French, Spanish colonisations; pre Civil War slave owners; pre colonisation slavery by the indigenous peoples? Or has is been predominately about the South's activities before, during and after the Civil War? (And, of course, the unlawful behaviour displayed by some of today's law enforcement officers.)
  9. Quite right, I'm still waiting for my Back to the Future Hoverboard...
  10. I cleaned some terminals with lime juice and an old toothbrush the other day - they came up a treat. Thanks for the Vaseline tip, I'll give it a go +1.
  11. Talk of space travel in other threads has got me thinking... Setting aside the limitations of our current technical ability, lack of resources and near-certain economical suicide for a moment: could adapting a Dyson Sphere* enable sun light to be used a source of energy for deep space travel? This is my first draft thinking... A giant lens fed by an array of mirrors is in such an orbit around the sun that enables it to focus a constant beam of photons towards our spacecraft - much like the way a child tortures ants with a magnifying glass. The more mirrors there are, the higher the energy reaching the spacecraft which is fitted with a large sail made from photovoltaic panels that converts this energy in to electricity. The spacecraft cannot out pace the beam so it should receive a constant source of photons as long as it stays in line of sight with the sun. If required, batteries or capacitors should be able to deal with those (infrequent?) occasions when a celestial body gets in the way. I don't know enough about intergalactic propulsion systems to say whether electricity can be used to create thrust in the near-vacuum of space, but I'm sure someone will find a way. I know that cosmic dust would scatter some of the photons so lessen the amount of energy reaching the spacecraft - and increasingly so the further away it gets - but would this be by any significant amount? Thoughts, anyone? * www.wikipedia.org/wiki/Dyson_sphere
  12. What I don't understand is what that effect would be for a single photon. I get that a single photon sent through a double-slit passes through both slits at the same time, before continuing to a screen where it displays an interference pattern. I also get that a vertical double-slit creates time dilation due to gravitational potential. This is where I am struggling: My intial thought was that the two "parts" of the photon would arrive at the screen at different times because one was travelling slower than the other due to gravitational time dilation. But this cannot be right as they are both travelling at c. (This thought was based on the fact that two synchronised atomic clocks seperated vertically will display different times due gravitational time dilation.) I then thought that it might be something to do with frames of reference that is beyond me for now. Thanks for reading.
  13. Hmmm. Maybe he was bored and just fancied a chat, or were you wearing an inappropriate amount of lycra for a man of your age?
