Serbian-American Inventor
Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla held over 300 patents and is responsible for inventing the laser, x-ray, radio, Tesla coil, Tesla turbine, neon signs, induction motor, remote control and many more. Tesla was a brilliant mind, but did not focus his energy on monetizing his inventions and had difficulty socializing. He died alone in a small hotel in New York.
The Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza pyramid complex bordering present-day El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. Correction: In the video I draw a line pointing to the middle pyramid as The Great Pyramid. The Great Pyramid is actually the northern most pyramid of the 3.
