Questions like “why do men and women act differently?” are age-old, with tangled, deeply buried answers. But that is why Catherine Dulac, a Howard Hughes Medical Investigator and a professor of molecular and cellular biology at Harvard University, has become so well respected by her neuroscientist colleagues for the originality and creativity with which she has brought important answers to light.
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.
L. Mahadevan is a professor of applied mathematics, physics, and organismic and evolutionary biology at Harvard University. He uses mathematics and physics to explore commonplace phenomena, showing that many of the objects and behaviors we take for granted, and consequently give little thought to, are quite extraordinary upon closer examination.
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.
