    I understand that in a country with a developed democracy such films are not shown,
    so I uploaded an excerpt from this video here.
    The Nazi criminal Dr Strangelove now serves as the new master -
    the US government.
    But only his hand, a prosthesis, is raised in the Nazi salute every now and then.
    But this does not bother anyone.

    Nicola Tesla developed radio, as did Reginald Fessenden...BEFORE Marconi...who became famous only for his wealth that allowed him to place his name on inventions he did not invent.

    I'll take Tesla's genius over Marconi's any day, thank you very much.

    In the same year, 1874, on August 27, the teacher Gulyelemo Marconi Augusto Rigi turned 24,
    just a year later he would already be a professor at a technical school in Bologna.
    The scientific world at that time was rather narrow and worked on science,
    often ignoring the consumer demands of society. It is known that Alexander Stepanovich
    corresponded with Augusto Riga and the conversation was about radio, even before Guglielmo Marconi
    demonstrated his "invention." Alexander Stepanovich was interested in science, like Augusto Rigi,
    Guglielmo Marconi was carried away by practical experiments for the sake of achieving concrete results.

    July 12, 1902, the Italian ship "Carlo Alberto" cast anchor near the severe bastions of Kronstadt.
    On board the ship was Marconi with his equipment - with it, he could receive signals coming from England,
    at a distance of 1,600 nautical miles.
    A few days later a red-bearded man appeared on board the ship - he seemed much older than his 43 years.
    Twenty-eight-year-old prosperous Guglielmo Marconi was very pleased with this visit.
    It was Alexander Stepanovich Popov. Popov was friendly, examined the radio room with interest,
    and said good-bye warmly. Popov kept good feelings for Marconi the rest of his life.
    Alexander Stepanovich died on January 13, 1906.

    There were many occasions of simultaneous discoveries/inventions in different parts of the world. The idea for those inventions seemingly occurred at the same time, relatively-speaking, and some people refer to them as "spontaneous discoveries/inventions" and this also happens in the world of physics, mathematics, chemistry and medicine.

    This infers that there was no copying, no harvesting of secrets, etc., but the most popular and well-known is what is usually recorded in history. At times, years after someone is attributed with some discovery/invention, another person is found to have come to the same conclusion. This has happened in many fields but the one usually recorded in history is the one made popular by publicists and historians at the first and later persons are sometimes questioned — even if it is proved that they had the idea and proofs first. These simultaneous inventions/discoveries are usually accepted by those inventors/discovers without protest as merely a natural occurrence, up to a point. More protesting is found with later historians who want to produce their works and present some degree of novelty in the process.

    Many times the line separating inventors as to who was first and who has the proper documentation to prove it is not very clear. It is then necessary to rely on contemporary writers for the evidence and then the allegiance to a particular person sets in by the proponents of whichever person they want to see as predominate.

    There comes a time when inventors/discovers must share acclaim by their adherents and not allow useless argument to rule the day.

    Fessenden's main claim to fame is that his system transmitted voice and music while other, mostly previous systems, only broadcast signals that were more often a system of codes.

    There are stories of Fessenden broadcasting music on the radio and ship's radio operators called others to witness the broadcast because it sounded crazy to the radio operator. Note that the easiest way to receive Fessenden's signal was with a crystal radio, at that time. Also note that the Fessenden system was on the long wave frequency area because a dynamo producing AC current was modulated and fed to an antenna. Such dynamos could not be operated in the higher frequencies because it was not mechanically feasible.

    What about Popov?
    :)

    Ok, I agree. But now in St. Petersburg at 3 am and I go to sleep.
    Tomorrow is a working day in Russia. It's all because of the May Day holiday.
    Tomorrow we work, and then we rest for 4 days. Celebration, by the way came from you.
    Happy 1 May Day!
