17. The Bold Quest to Launch the Internet in Space

Vint Cerf is one of the fathers of the internet. Decades ago, he and Robert Kahn developed the architecture and protocol suite known as Transmission Control Protocol/Internet Protocol (TCP/IP). Anyone who has ever surfed the web, sent an email, or downloaded an app has them to thank.

Now, Cerf wants to boldly go where no internet has gone before. He's designing an interplanetary internet. But extending the internet to space isn’t just a matter of installing Wi-Fi on rockets. Scientists have novel obstacles to contend with. In this new video, Cerf discusses how an internet in space.

21. How to Shrink Big Data

Jelani Nelson, a computer scientist at the University of California, Berkeley, expands the theoretical possibilities for low-memory streaming algorithms. He’s discovered the best procedures for answering on-the-fly questions like “How many different users are there?” (known as the distinct elements problem) and “What are the trending search terms right now?” (the frequent items problem). Nelson’s algorithms often use a technique called sketching, which compresses big data sets into smaller components that can be stored using less memory and analyzed quickly.
