+# Heilmeier Catechism
+
+George Heilmeier was a program manager at the Defense
+Advanced Research Projects Administration (DARPA) who was
+flummoxed with research proposals for artificial
+intelligence. In order to quickly sort through the
+proposals, he developed an 8 question system to quickly cut
+through the muck.
+
+This is the Heilmeier Catechism:
+
+1. What are you trying to do? Articulate your research with
+   absolutely no jargon.
+
+2. How is it done today and what are the limits of current
+   practice?
+
+3. What's new in your approach and why will you be
+   successful?
+
+4. Who cares? If you're successful, what difference will it
+   make?
+
+5. What are the risks?
+
+6. How long will it take?
+
+7. How much will it cost?
+
+8. What are the midterm and final exams? How will you
+   measure success?

+
+***High-Assurance Hybrid Controller Synthesis from Logical
+Specifications*** 
+
+## **What am I trying to do? No jargon!** 
+
+The goal of this research is to use formal methods to create
+hybrid controllers with provable guarantees of performance
+and safety. Hybrid control systems are control systems that
+have distinct changes in system dynamics under different
+conditions, which are often called modes. Modes are often
+defined by design requirements, and as such can be easily
+translated into formal specifications. This research will
+will eliminate the possible introduction of accidental
+errors while building controllers by automatically
+synthesizing the mode switching behavior from design
+requirements. Controller behavior within modes will be
+verified using reachability analysis.

+1. Hybrid Controller Synthesis from Logical Specifications

+
+Okay so mixing these:

+*Formally Tractable Hybrid Controller Synthesis from Logical
+Specifications of Regulatory Requirements* 
+
+It's long. But Hybrid controller synthesis from logical
+specifications might not be enough? Also 'logical
