The Untold Story of Wireless Communication: Marconi, Lodge, and Tesla

📡 Guillermo Marconi is often credited with inventing the wireless Telegraph, but he wasn't the first to make a wireless transmission or invent the devices used in his experiments.

👨‍🔬 Despite being uneducated and skipping subjects like math and physics, Marconi built a wireless Telegraph Empire, won the Nobel Prize, and impacted Nikola Tesla's life.

🌐 In 1894, Marconi's inspiration from Heinrich Hertz's obituary led him to pursue the goal of making wireless Telegraph travel around the world.

Hertz discovered invisible electromagnetic waves

Marconi used Hertzian waves to send long-distance wireless Telegraph's

Lodge invented the coherer, a device that showed radio waves can travel long distances

📻 Marconi improved on the coherer and discovered the effectiveness of tall antennas and grounded antennas.

💡 Marconi's biggest contribution was his belief in the ability of radio waves to travel long distances, despite the prevailing belief that they couldn't due to the Earth's curvature.

⚡ Nikola Tesla had already discovered how to generate powerful radio waves using an AC source.

📻 Tesla invented the Tesla coil, a high-voltage alternating current transformer.

💡 Tesla had grand ideas for long-distance Wireless lighting and electrifying the atmosphere.

👂 Marconi built powerful radio receivers and transmitters, claiming to have received signals over long distances.

📻 Marconi was able to receive signals from Cornwall as far as two thousand miles away, but only at night.

☀️ During the day, Marconi could only receive signals at a distance of 700 miles, which he called the daylight effect.

🌐 Marconi believed that radio waves skimmed along the surface of the earth, while Tesla thought they traveled through the earth.

📡 Marconi, Lodge, and Tesla were all involved in the invention of wireless technology.

💼 Marconi obtained patents for wireless technology, but Tesla believed Marconi was using his patents.

💰 Due to financial difficulties and the loss of funding, Tesla had to give up his wireless project.

The funeral of a prominent individual marked the end of an era without man-made radio signals.

In 1937, radio signals transitioned from Morse code to broadcasting music and news.

The explanation of the physics behind the first radio broadcast will be discussed in the next video.
