SUMMARY

The discussion centers on the ENIAC, the world's first general-purpose electronic computer, which stood 10 feet tall, occupied 1,000 square feet, and weighed approximately 30 tons. It utilized over 70,000 resistors, 10,000 capacitors, 6,000 switches, and 18,000 vacuum tubes, consuming 150 kilowatts of power. Additionally, the conversation shifts to the Russian Ekranoplan, a Ground Effect Vehicle developed by Rostislav Alekseev, which could travel over 400 km/h and weighed 540 tons fully loaded. The Ekranoplan was designed for military transport and could carry over 100 tonnes of cargo.

PREREQUISITES
  • Understanding of electronic components such as resistors and capacitors
  • Familiarity with the concept of Ground Effect Vehicles
  • Knowledge of military transport technologies
  • Basic historical context of computing technology development
NEXT STEPS
  • Research the technical specifications and historical significance of the ENIAC
  • Explore the design and operational principles of Ground Effect Vehicles
  • Investigate the military applications of the Ekranoplan
  • Learn about the evolution of computing technology post-ENIAC
USEFUL FOR

This discussion is beneficial for historians, technology enthusiasts, and engineers interested in the evolution of computing and transport technologies, particularly those focused on military applications and early electronic devices.

:bugeye: I'm going to have to google more about that one!
The guy stuck a couple of sticks (hence the name) into the ground a measured distance apart, then compared the shadow lengths to work out the curvature of the Earth.

Okay, looked it up. Phew, no librarians had to get thrown down wells! :smile:

Eratosthenes, a Greek geographer (about 276 to 194 B.C.), made a surprisingly accurate estimate of the Earth's circumference. In the great library in Alexandria he read that a deep vertical well near Syene, in southern Egypt, was entirely lit up by the sun at noon once a year. Eratosthenes reasoned that at this time the sun must be directly overhead, with its rays shining directly into the well. In Alexandria, almost due north of Syene, he knew that the sun was not directly overhead at noon on the same day because a vertical object cast a shadow. Eratosthenes could now measure the circumference of the Earth (sorry Columbus) by making two assumptions - that the Earth is round and that the sun's rays are essentially parallel.

(Shh...don't tell all those fans of Columbus that people already knew the Earth was round long before his time!)

Okay, so I missed a couple of details... :redface: (Working from memory here.)

I don't know if it was too easy, it just popped into my mind...darn, now I have to think of one! Anyone have a clue ready who wants to take my turn?

Okay, here we go:
Brightly colored and born in Denmark, Moonbear likes their studs.

I know I've needed to go back for those maps a few times. :smile:

Are there any studs that Moonbear doesn't like?

Hm, I've seen chocolates and candies that look like jewels...

I'm thinking some kind of horse native to the region.
 
  • #919
Yeah, me too. Maybe jutlands?

I was sort of thinking along the line of the jewels themselves, but I can't for the life of me come up with what kind Denmark produces. Amethyst?
 
  • #921
Nope, not horses or jewels.

Okay, the studs function better with tubes.
