ART Meeting: Temperature of the Atmosphere – let the numbers do the talking
Monthly meeting of the Association for Rational Thought. For those who would like to get together after the talk, we will be having lunch at Parker's. Larry Busby will talk about "Temperature of the Atmosphere – let the numbers do the talking." With the mixed messages in the media, he decided to see how far he could get in determining the extent of human contribution to warming of the planet. Larry's bio: RESC Newsletter May 2018 Larry Busby receives RESC 2018 Lifetime Achievement Award The RESC Board is pleased to announce that long-time member Larry Busby was selected by the board to receive the 2018 Lifetime Achievement award for his many years of innovative engineering and in particular his creative solutions to some early engineering problems in the NASA space program. Here are some of the highlights of Larry’s career: Graduated from Purdue University in 1949 with BSEE Delco Radio Division – General Motors Corporation[masked] Stromberg Carlson Division of General Dynamics[masked] Designed transistor circuitry for military electronics equipment. Awarded Patent 3,011,052Transistor Squelch Circuit. Licensed Professional Engineer State of New York. Crosley Division of AVCO/Cincinnati Electronics[masked] (currently L3T- Cincinnati Electronics) My first project was to design a transistor version of their miniature-tube Range Safety Receiver. During the design, I found a way to improve the tone filters to make them immune to noise activation. I received patent #[masked] for this circuit Sept 1, 1964. Over the next 20+ years, we received many contracts for launch vehicle range safety receiver/decoders and satellite uplink receiver/decoders. They were supplied in redundant pairs and each used from four to eight noise-immune filters. Equipment used on the Saturn V used a “secure” tone sequence and combination format. Since there were no failures of this launch vehicle (used for the man-on-moon program), the equipment, very fortunately, never had to be used. Several thousand noise-immune filters are in satellites that are currently in orbit around the earth. Five receiver/decoders are used on each Space Shuttle – two on each solid-rocket booster, one on the external tank. We used an A/D converter and microcomputer with a TI 9900 microprocessor and software I designed to replace the eight noise-immune filters. The software maintained the noise-immunity and provided a crystal stable and narrower bandwidth response. The added versatility of the microprocessor allowed an improvement in security by a factor of over 3000 compared to the system used on the Saturn V. An L3T -Cincinnati Electroics write-up: Mr. Busby’s contributions to various NASA programs have earned him their highest award, the NASA Launch Honoree Award. This award is conferred for exemplary performance while working on critical hardware for man-rated vehicles. Cincinnati Electronics’ Space Products have gained a reputation as technically the finest available due to Mr. Busby’s 29 years of engineering leadership. Mr. Busby’s accomplishments have been a major factor in the increase of Space Products awards totaling less than $1 million in 1967 to $16 million projected for 1988.

What we're about

Are you a mad scientist or just a science groupie? Whether you are an expert of science or a novice like me, if you love science then this is the group for you!! This group is for people who love science, embrace science, find science interesting or simply want to learn more about their world. I am someone who loved science as a kid but lost it somewhere along the way due to religion, sexism and our educational system's ability to make it as boring as possible. Now as an adult, I find myself wanting to dive back in!! I want to learn and educate myself about the world around me. I want to understand how things work. I want to have knowledge so I can no longer be duped by pseudo-science and charlatans. Most importantly, I want to have fun and I've learned science can be oh so much fun!!! Join us as we explore all facets of science. I intend to visit museums and exhibits, host talks and discussions about various science topics, enjoy films, attend educational programs, and participate in various science activities such as stargazing, guided nature walks, and public lectures. I am looking for any experts interested in sharing their knowledge at an event or class or any person interested in being an assistant organizer. As I've stated, I am not an expert, just someone interested in learning more. Feel free to offer your knowledge, organizing skills or suggest meetups.

Be sure to like our Facebook page as well to get information on events, science, memes and to enjoy discussions with like-minded folks.
