I travelled a lot in 2017. The most I have ever traveled before.\u00a0I flew 163,195 miles which is equivalent to 6.6x around Earth. I was on 114 flights. I spent almost 400 hours (~16 days) on a plane. I visited 17 countries: Austria, Argentina, Canada, Chile, Colombia, France, Germany, Greece, Guatemala, India, Mexico, Netherlands, Portugal, Spain, Switzerland, UK, Uruguay. I was in Austin for 164 days (my home), 61 days in Europe, 28 days in Colombia and 16 days in India. I slept 30 nights at a Marriott, 27 nights at an Airbnb and 13 nights on a plane.<\/p>\n

Given all this travel, I asked myself: what was my most memorable event of 2017<\/em>?<\/p>\n

The answer was simple: dinner at the\u00a0Royal Society of London<\/a> with\u00a0Bob Kowalski<\/a> and\u00a0Keith Clark<\/a><\/em><\/strong>.<\/p>\n

In July, I gave a lecture at the 2017 Reasoning Web Summer School<\/a> and attended the RuleML+RR 2017 Conference<\/a>. The conference dinner was at the Royal Society of London. Bob Kowalski gave the dinner speech titled “Logic and AI \u2013 The Last 50 Years<\/a>\u201d. It was the 50th anniversary of when he started his PhD, which gave the rise to logic programming<\/a>. Additionally, by pure coincidence I sat next to Keith Clark. The combination of sitting next to Keith Clark and listening to Bob Kowalski\u2019s is what made this my most memorable event of 2017<\/p>\n

Why?<\/p>\n

Early during my PhD, my advisor, Dan Miranker<\/a>, encouraged me to read about the 5th Generation Japanese Project<\/a> (if you don’t know what this is, go look it up NOW!) During my research, in order to trace back the relationship between Logic and Data, I encountered the landmark 1977 Workshop of Logic and Data Bases<\/a> organized by Herve Gallaire, Jack Minker and Jean-Marie Nicolas. That workshop is where Ray Reiter<\/a> presented his paper on Closed World Assumption<\/a>, Bob Kowalski presented his paper on Logic for Data Description and Keith Clark presented his paper on Negation as Failure<\/a>. I even have a copy of the proceedings:<\/p>\n

\"\"<\/div>\n

 <\/p>\n

Every time I give a talk on this topic, I reference that 1977 workshop to provide historical context of where we are today. See slide 4:<\/p>\n

Bob concluded with two open questions:<\/p>\n

1) What is the relationship between declarative and imperative representation of knowledge?<\/div>\n
2) What is the relationship between different types of rules?<\/div>\n

As you can imagine, sitting next to Keith Clark, listening Bob Kowalski’s talk and having the opportunity to chat with them is what made this a truly amazing evening.<\/p>\n

What an evening! An evening I will never forget! Thank you Bob and Keith!<\/p>\n

Oh, I even saw Alan Turing\u2019s Certificate of a Candidate for Election into the Royal Society.<\/p>\n
