  2. CrooksJoe, You have a very philosophical point in you first sentence. Religious people do not "inexplicably" believe in God. They have Theology to back them up. You'll like the vid as an explanation regarding the Big Bang and what came before it. Extinction Rebellion are on your side vis-a-vis the import of your last sentence.
  3. Wavelength is determined by momentum, and a dog has a lot more momentum than an electron. The wavelength of a material object is given by Planck’s constant divided by the momentum,which is mass multiplied by velocity. The wavelength of a 20kg dog -out for a stroll- is about 10 to the power minus 35 metres.That is about a millionth of a billionth of a billionth of the wavelength of, say the electrons that make up a wafer of nickel.. How does this compare to the size of a tree ? A dog’s wavelength when compared to the distance between two atoms is like the distance between two atoms to the distance of the solar system. There’s no way of seeing the wave associated with a dog diffract off a crystal of nickel,never mind pass around both sides of a tree at the same time. Cutting to the chase, As the mass of a particle increases,its wavelength gets shorter,and it gets harder to see wavelength effects directly . A dog-or for that matter a person- is a collection of biological molecules which have wave like properties-just like everything else Everything is made of waves Are electrons really particles that act like waves,or are photons waves behaving like particles ? Electrons and photons are both examples of a third sort of object in space. Our third object- let us call it the “Bonzo “ particle- has wave like properties at the same time as it has particle like properties. Note: “Crystal to the physicist refers to any solid object with a regular and order arrangement of atoms inside it.” “Diffraction patterns are an unmistakable sign of wave behaviour.” Davisson and Thomson shared a Nobel Prize in 1937 for demonstrating the wave nature of the electron. Alternative name for the particle mentioned above , "the Bonio particle." Source:How To Teach Quantum Physics To Your Dog. Author:Chad Orzel..ISBN 978-1-85168-779-4 Reprint 2010.
  4. Cyclone, I'll leave it a little longer before I jump back in . It apparently has to do with "Wavelength". Let's see what others have to say.
  5. So,if all material objects are made up of particles with wave like properties, why don't we see dogs difracting around trees ? If a stream of electrons can diffract off two rows of atoms ,why can we not see a dog run a around both sides of a tree simultaneously ? Good doggy!
  6. The coolest of the cool. I've just taken delivery of my new valve trombone. There's a very handsome young Gerry Mulligan playing on this video. Grab a drink,put your shades on and drift away.

  8. Mac 33, With respect,in case you don't want to read through the whole of the paper: ". In summary, this meta-analysis suggests that a prophylactic vaccine against HPV16/18 has the potential to prevent more than two-thirds of worldwide ICC and half of HSIL ". I would recommend that GUM clinics offer sexually active people a HPV vaccination. They can clearly benefit from it. I do believe one can obtain HPV vaccine on-line and self administer. Scholarly articles for Human Vaccines and immunotherapeutics HPV Human papillomavirus type distribution in invasive … - ‎Smith - Cited by 1788 … vaccinia virus encoding human papillomavirus types … - ‎Borysiewicz - Cited by 603 … metastatic tumors expressing human papillomavirus … - ‎Ji - Cited by 138
  9. I'm puzzled why people reject a procedure that is overwhelmingly proven to be effective in the majority of the population. Yes, there may be some adverse reactions to some vaccines. But that does not disprove the science.
  10. I agree we should not censor. The medical profession and the pharmaceutical industry are not infallible ,they make mistakes. Consequently they should be open to examination . The science supporting vaccination is impeccable . I put two links that examined HPV and other kinds of cancer and they were removed. It is something to be celebrated that the HPV vaccination programme will eventually rid humanity of the cancers associated with HPV. Mac33-and others- may draw our attention to adverse events caused by vaccination. However, vaccination is a proven science and it works for the majority of us who choose to undergo the programme.
  11. Where has the rest of this thread gone?
  12. Hurrah , ! The end of cervical and anal cancer is within sight at last. It will be available to young people as well as adults. https://www.bbc.co.uk/news/health-48758730
  13. Tinfoilhat You have it spot on. https://www.huffingtonpost.co.uk/entry/deepfake-videos-and-the- threat-of-not-knowing-whats-real_n_5cf97068e4b0b08cf7eb2278?guccounter=1&guce_referr "Newscasters could announce the start of a nonexistent nuclear war. Deepfake technology threatens to provoke a genuine civic crisis, as people lose faith that anything they see is real". If people have not read McLuhan ,now is the time to do it. I do believe that his work is back in the Curriculum at some Uni's
  14. Rolling J McLuhan was a communications guru, he wrote extensively about mass communications and its social impact. Apparently it is now possible to cobble together -by means of the Internet - what appears to be real people indulging in all kinds of activities. Like Donald Trump declaring war on Russia-and how do we know it's not real ? Or a weather bomb of extreme weather is about to hit-so dash out and raid Tesco.
  15. The age of the "Deep Fake" is upon us. An age when anything can mean anything to anyone. Marshall McLuhan was right: " I have insisted that any new structure for codifying experience and moving information,be it alphabet or photography has the power of imposing its structural character and assumptions upon all levels of our private and social lives-even without benefit of concepts or conscious acceptance........That is what I've always meant by "the medium is the message" (On McLuhan, by Paul Benedetti and Nancy DeHart), Reality will become a quaint notion .
