Vinton Cerf visits GSFC

On May 26, 2015, Vinton Cerf, co-developer of the TCP/IP protocols which underpin the entire Internet and current Chief Internet Evangelist for Google visited GSFC to deliver the IS&T (Information Science & Technology) Colloquium, entitled, "Tracking the Internet into the 21st Century." He described his own and the Internet's background (back to DARPA work in 1969), and offered ideas about IPv6 and the future of the Internet. He even discussed interplanetary communication using relayed signals.

Here is a sampling of photos from his talk.

"Medium" images are screen-size (<350K, 1000x667 pixels), while the full-resolution images are much bigger (up to 14MB, 5472x3648 pixels).

Technical notes:
Photos were taken with a Canon EOS 70D (20 megapixel) DSLR with a 70-200 f/4 L lens, mounted on a monopod. All shots were done with available light at 1/80 sec at f/4 at ISO 3200 (Auto ISO). The RAW images were processed with Adobe Lightroom 5.4 (Adobe Camera Raw 8.4).

(The lighting (quantity and direction) in the Building 3 Auditorium aren't great.)
