 Nikola Tesla (1856-1943) was a Serbian-American inventor, electrical engineer,
and physicist who is best known for his contributions to the development of the
modern alternating current (AC) electrical system. Tesla was born in the town of Smiljan in modern-day Croatia, then part of the Austro-Hungarian Empire.
Tesla attended the Austrian Polytechnic in Graz and later studied at the University
of Prague. He immigrated to the United States in 1884 and began working for Thomas
Edison's company, where he developed and improved a number of electrical devices.
However, Tesla and Edison had a falling out, with Tesla resigning in 1885 due to
a disagreement over payment.
Tesla went on to work for several other companies and eventually established
his own laboratory, where he worked on developing his own ideas for electrical devices.
In 1891, he invented the Tesla coil, a high-voltage transformer that is still used
in radio and television technology today.
Tesla also contributed to the development of the AC electrical system, which
is now used to power homes and businesses around the world. He was a fierce competitor
of Edison, who advocated for the use of direct current (DC) electricity instead
of AC. Tesla's AC system won out in the end due to its greater efficiency and the
ability to transmit power over long distances. It epic challenge has been called
"The War of the Currents" or "The
Battle of the Currents."
Tesla held over 300 patents for his inventions, which included the Tesla coil,
the Tesla turbine, and the Tesla oscillator. He was also interested in wireless
communication and developed a system for transmitting messages and power wirelessly
over long distances, but he was unable to secure sufficient funding to continue
developing the technology.
Despite his many contributions to science and technology, Tesla struggled financially
for much of his life and died in relative obscurity in a hotel room in New York
City in 1943. However, his legacy has lived on, and he is now recognized as one
of the most important inventors and scientists of the modern era.

AI Technical Trustability Update
While working on an
update to my
RF Cafe Espresso Engineering Workbook project to add a couple calculators
about FM sidebands (available soon). The good news is that AI provided excellent
VBA code to generate a set of
Bessel function plots. The bad news is when I asked for a
table
showing at which modulation indices sidebands 0 (carrier) through 5 vanish,
none of the agents got it right. Some were really bad. The AI agents typically
explain their reason and method correctly, then go on to produces bad results.
Even after pointing out errors, subsequent results are still wrong. I do a
lot of AI work and see this often, even with subscribing to professional
versions. I ultimately generated the table myself. There is going to be a
lot of inaccurate information out there based on unverified AI queries, so
beware.
