    I know I'm replying to a 7 months old thread, but reading it got me wondering is there a limit to frequency? Well, I'm sure there is, my question is more like what is it? Is it when the wavelength nears or reaches plank legnth, if that even makes any sense?

    He might have won the very first Nobel Prize, had he not passed away just a few years prior, and much too young, wasn't he in his late-30s or early-40s?

    In fact, I believe that had Hertz remained alive and won his prize, the Nobel Committee would not have felt obliged to give it to Marconi a few years later.

    Marconi was a back-stabbing asshole who became one of the wealthiest men in the world by abusing the gentlemanly trust of others, and coasting on someone else's technology - particularly the way crystals oscillate, and some of them serve nicely as a sort of "translation point" between electromagnetic waves and the physical apparatus that transmits and/or receives the signal.

    He might have won the very first Nobel Prize, had he not passed away just a few years prior,

    Basically the same thing happened twenty years later with Henrietta Swan Leavitt, who made a discovery that's essential to figuring distances in space. She noticed something while working as a computer at Harvard College Observatory that eventually became known as Leavitt's Law. Her Nobel nomination was halted because she passed away and the award is not given posthumously. Hubble's work heavily relied on hers.

    Faraday, after demonstrating how moving a magnet through a coiled wire induced a current in the wire was asked by a visiting statesman what was the use of this.

    Faraday responded, "In twenty years, you will be taxing it"

    Similarly, at a demonstration of hot air balloons in France, Benjamin Franklin was asked "Of what use is this?"

    Franklin replied, "Of what use is a newborn baby?"

  • Funnily enough, Faraday seemingly also understood that the Electric Field only possesses a potential in the absence of changing magnetic fields. Because only in the absence of changing magnetic fields, the rotation of the Electric Field is zero, and only then it has a potential.

    If you think about it, almost all computer-technology is radio. Wifi, bluetooth, GPS, radar, and cellular are literally radio. Meanwhile everything else runs on transistor tech developed and refined... for radios.

    Our modern economy couldn't exist if people like Hertz and Maxwell didn't get to toy with their useless hobbies. But we can't rely on the curiosity of the leisure class anymore. Basic research is expensive, necessary, and a public good. I'm afraid that the Trump regime has already spoiled the secret sauce that makes America the technology leader of the world.

    Even more than that, just proving Maxwell was right was a key stepping stone to all of modern physics. Maxwell, not Einstein, was the first to show that the speed of light is invariant, and Einstein's Relativity was a framework for explaining how tf physics works if that's actually true. Prior to Einstein, physists all just kind of assumed there was some flaw in Maxwell's theorems to lead to this crazy speed invariance, but as the evidence just kept piling up in favor of Maxwell, they started having to wrestle with the uncomfortable thought that this could actually be true. In this sense, Hertz can also be thought of as an important step to Einstein and beyond, and almost all of our modern technology.

    Transistors were mostly developed for telephone systems (the ones with wires) as a replacement for tubes. And the modern tech used for radios is very different from that used for computers.

    Ithink you could be more charitable in your reply. Transistors were developed to replace tubes in telephone systems... Okay but the tubes had been developed to where they were because of their usefulness in radio.

    And while computers don't inherently rely on radio, it's radio communication that's taken computers from one in every office to one in everyone's pocket. Right? The main thrust of the previous commenter is true.

    You could have an internet (sort of) without computers. Consider Teletypers, FM Radio broadcasts, or Telephone.

    I mean, it would be some 25 years until the radio was invented. And Hertz' machine required a 30kV spark on a 2.5m meter long antenna with 2 solid 30cm zinc spheres, and his transmission range was something like "barely down the hall".

    Not the most practical method.

    ok but now, where does the word "Funke" (spark) come from?

  • source

  • hideshow 2 child comments
  • [–] 2 points 1 year ago (2 children)

    Pretty much the first type of commercially viable radio transmitter was the spark-gap transmitter ("Knallfunkensender" in German). It worked by charging up some capacitors to up to 100kV and then letting them spark. This spark sent a massive banging noise on the whole radio spectrum, which could then be turned into an audible noise using a very simple receiver. That was then used to send morse codes (or similar encodings).

    They went into service around 1900, and by 1920 it was illegal to use these because they would disrupt any and all other radio transmissions in the area with a massive loud bang.

    “Knallfunkensender”

    Literally "Bang-Sparks-Sender".

    Are you sure it's because of the radio spectrum bang? I always thought it was because of the audible bang.

    If someone operated such a thing today, any guesses what the death zone for electronic devices would be?

  • source

  • hideshow 1 child comment
  • [–] 2 points 1 year ago

    It's a broadband bang that can be heard across the whole spectrum. It becomes audible when listening to radio broadcasts.

    Regular radio transmissions are comparatively narrow band, allowing lots of simultaneous transmissions in the same airspace, each on its own frequency. The spark gap transistor is very wide band, so it basically sounds as if you are sending a bang sound across all radio frequencies at the same time.

    It wouldn't destroy radio equipment, but the radio transmissions. It's basically as if you'd use a radio jammer as a morse code transmitter.

    Those practical methods would never have existed if not for Hertz' experiments. Those were 25 years of other scientists, having seen that this new concept exists, refining his contraption into what eventually would become the machine that we know as a radio.

    I feel like this is a very "scientisty" thing - the theoretical aspect is so fascinating and being able to fit all the pieces into a model that is mathematically accurate is the reward.

    Considering the practical application of the model and how it can benefit society (or in other words, be marketed for profit) takes a different set of skills.

    I absolutely detest the equivocation of "benefits society" and "marked for profit".

    Plenty of things have been discovered to have practical applications which can benefit society yet are shelved or have its implementation frustrated because it cannot be exploited for profit or threatens the profits of a preexisting application which it would replace.

    It's not always immediately obvious to what end you can use a new innovation. For instance, the Romans discovered and built a steam engine. But nobody connected the dots that it could be used to power a train.

    To me, it showcases the main reason why we need to collaborate. Only together, we can exponentially increase the potential of everything we build.

    By August 1895, Marconi was field testing his system but even with improvements he was only able to transmit signals up to one-half mile, a distance Oliver Lodge had predicted in 1894 as the maximum transmission distance for radio waves.

    I suppose beyond the engineering know how required they were looking at possible transmission ranges and thinking it simply wasn't practical, square law and all that.

    This.

    There are often actual limits to what can be done, and there are practical limits. Especially in the early days of a technology it's really hard to understand which limits are actual limits, practical limits or only short-term limits.

    For example, in the 1800s, people thought that going faster than 30km/h would pose permanent health risks and wouldn't be practical at all. We now know that 30km/h isn't fast at all, but we do know that 1300km/h is pretty much the hard speed limit for land travel and that 200-300km/h is the practical limit for land travel (above that it becomes so power-inefficient and so dangerous that there's hardly a point).

    So when looking at the technology in an early state, it's really hard to know what kind of limit you have hit.
