Einstein refused the Copenhagen interpretation of quantum mechanics. "God does not play dice", he said. In 1935 he published an article with Podolsky and Rosen in which they described what for them was a paradox. But that paradox resulted real, and gave rise to a new branch of physics, which is still flourishing. Tullio |

Many States invest money on quantum computers. According to theregister.co.uk the British Gov shall invest 338 million dollars (or pounds, if I understand correctly). The US Chamber of deputies proposed a 1.27 Billion dollars investment, but this measure has yet to be approved by the US Senate. I have taken 3 online courses on quantum computers, one by UC Berkeley, one by Keio University, Japan, and one by Delft Technical University, Nederlands, which was the most difficult for me. I intend to take a fourth course by Delft University very soon. Tullio |

Why Quantum Computers Will Be Super Awesome, Someday https://www.bloomberg.com/news/articles/2018-06-29/why-quantum-computers-will-be-super-awesome-someday-quicktake Yes. Someday:) Understanding Quantum Mechanics https://futurism.com/understanding-the-physics-of-our-universe-what-is-quantum-mechanics/ For around a century now, physicists all over the world have been trying to make sense of quantum phenomena. But so far, all attempts to unify quantum mechanics with the common physical laws of our everyday environment have been in vain. We are left with several probabilities instead of certainties.

New Scientist has sent me a link to the proceedings of a celebration in occasion of David Bohm's centenary birthday. Unfortunately, my browser (Firefox) cannot render the videos. Tullio |

Maybe this could be helpful to fix the video problem. https://support.mozilla.org/sv/kb/fix-common-audio-and-video-issues David Bohm is another scientist that belive in the Many World interpretation. That the "cat in a box" example by Schrödinger is real . "Forget standard quantum weirdness – the world Bohm revealed is a more profoundly and mysteriously interconnected place than we ever imagined." https://www.newscientist.com/article/mg23431200-200-realitys-comeback-the-hidden-network-that-controls-what-we-see/ Actually those quantum effects are real since we can measure them. The irony is that Einstein who hated the quantum ideas was the first to introduce the ideas of the quantum world. He did that when publishing the paper on the photoelectric effect back in 1905 that he got his Nobel Prize for. |

Higher mathematics, we'll get there eventually. Or we might get a boost from E.T. Too many are thinking inside the box & too scared to think outside of it. |

Some say that quaternions are the real numbers of quantum theory. But there is a lady, whose name I forgot to write down,who is already using octonions. Tullio |

The breakthrough will come. The only question then is - When? |

It's one thing to move tangible molecules around, but I don't see how they're going to be able to teleport the ethereal nature of consciousness along with the person. ![]() |

No more cats! According to 'Nature" magazine Schroedinger's cat has been replaced by Eugene Wigner in 1967 by one physicist doing an experiment. Now two physicists of the ETH Zurich, Einstein's university, have replaced the Wigner lone physicist by two physicists, Alice and Bob, doing the same experiment, that is checking if a coin has landed head or tail. Their results are contradictory. The cat is saved! Tullio |

Erwin Schroedinger book "What is life ?"published in 1947 based on a series of lectures at Trinity College in Dublin started what today is know as molecular biology. Tullio |

I have read about the ETH thought experiment in a "Nature Briefing" newsletter. As soon as I get an online copy of "Nature" with more information I shall return to the subject. Maybe Schroedinger's cat can be forgotten. Tullio |

this whole concept that things aren't existing till there is someone to measure it or take knowledge of it... for me is just ravings of twisted mind humans. I too tend to think this way. However, the other day I had a Eureka moment...... I have this nice, very bright LED flashlight. If I hold it in my hand and turn it on nothing at all happens until the beam hits something. If I aim it at the sky there is no discernible event happening unless there is dust or rain in the air...if I place my hand a foot or so in front of the beam I see it illuminated; but there is nothing in between the flashlight and my hand. Its almost as if there is an electromagnetic field disturbance which is not apparent until I query the field by putting my hand in the path of the beam. This is a little more certain than the entangled electron idea but not the same as the tree falling in the forest and nobody to hear the sound--which took place as defined by compression of the air but also defined as exciting nerves in the brain of a human or animal. |

it all changes anyway because you looked at it. Thats right; you can't look at it without hitting it with light (a so called "Photon"). This will have an effect on a very small object since the photon has, or conveys, energy. Bohr was able to withstand all of Einstein's thought experiments attempting to disprove the uncertainty principle at the Solvay conferences long ago. We would do well to remember this as we question relativity and the Lorentz transformations . It requires light to tell an observer what is happening and light does take a finite time to travel to an observer. At extremely high speeds there is a compression of length as seen by the stationary observer as it takes time for the front and back of an object to be seen. |

Light travels at about one billionth of a second/foot. If I open my front door and observe my 15 foot long car in the driveway, the image of that car in it's entirety will hit my retina all at once, not in two stages 15 billionth of a second apart.Correct, but the light that is hitting your retina left the car at different times. |

E(x,t) = Emax Cos(kx - ωt + φ) = Emax Cos((2π/λ)x - (2πf)t + φ),Why? Do you understand it? |

Sorry I can't accept that.Some people have issues with reality. Even Einstein. God is the dice. E(x,t) = Emaxcos(kx - ωt + φ) = Emaxcos((2π/λ)x - (2πf)t + φ) Someone dropped some spaces from the formula. |

The fact that we can have abstract theories about these sorts of things ties in with what I said a few posts back about the nature of consciousness and whether it can be teleported in the same way as the body. I feel like cryonics is also missing the mark as I don't think consciousness can be dethawed like frozen orange juice. ![]() |

E(x,t) = Emaxcos(kx - ωt + φ) = Emaxcos((2π/λ)x - (2πf)t + φ)That equation is the wave equation of an electric field propagating in a vacuum derived from one of Maxwell’s equations. How the graph looks like when also the magnetic field B is included. ![]() Not only scientist understand and use Maxwell’s equations but also engineers. Perhaps in white coats as well:) |

From your link:Some people have issues with reality. Even Einstein. God is the dice. It's true that Einstein never accepted quantum mechanics, but the reason was much more nuanced than a flat-out rejection of the theory. After all, Einstein won a Nobel Prize in 1921 for describing the photoelectric effect — a phenomenon that led to the development of quantum mechanics.But without many thinking outside the box, we would not be where we are today. The biggest drawback to science is the many who concentrate their thinking on what they have experienced & know. The concept of thinking outside the box is alien to them. A closed mind has many boundaries. Edited to remove repeated quote. |
