World History - Level 47: The History of Modern Technology

Welcome to Zone 31: The Modern Era of Technology!

Before we jump into the quiz, look at the sheer physical size of the very first commercial mobile phone.

> **Key Insight:** The DynaTAC mathematically cost $3,995 in 1983 (over $12,000 today). It took exactly 10 hours to fully charge, and mathematically only gave you 30 minutes of talk time before the battery completely died!

Explore exactly how rapidly we went from that massive "brick" to the sleek smartphones we use today with this interactive timeline:

It is mathematically incredible to think that the infrastructure you use to host your web databases (like Firebase), manage your custom domains (like Hostinger), and deploy your frontend code (like Vercel) are built entirely on the massive networking breakthroughs of just the last two decades.

Let's charge the batteries and completely conquer Level 47!
