Page 541 queen substance = A *pheromone, trans-9-keto-2-decenoic, that is secreted by the mandibular salivary glands of a queen honeybee and inhibits the development of ovaries in the worker bees in the colony.
As the queen ages, the secretion of queen substance diminishes; the workers then construct brood cells for future queens, which they feed exclusively with *royal jelly.
I studied economics in the era (the 70's) when Samuelson reigned. It was the golden age. This brought back some happy memories. Not sure why he disliked the faculty club in recent years.
I'm planning on becoming a mechanical engineer but I'm considering frontier sciences as well. This video was very insightful but I was really sad to hear at the very end that his family didn't really ever get to see him. He talked about how close his kids are to each other and their mother but he didn't say they were close to him. Maybe I'm reading to much into it but if I'm not than this is very sad
The discussion of Gen. MacArthur and Sperry was amazing. Forrester was a fairly young guy with tremendous impact. Best 2 hours I have spent in a while watching.
Someone smart please explain how a basketball score discrepancy of a few points out of a couple hundred is not a standard distribution. If NBA games are commonly won within a few points, why should the sigma be broader?
It shouldn’t. It’s obvious he tried unsuccessfully to participate in athletics. He seems bitter. He’s use to being awesome at intellectual pursuits and has had great success. Failing at another endeavor made him spiteful. His remarks regarding the purpose of sports are particularly revealing. Oh well. Nobody’s perfect. He was a smart man and contributed to the advancement of human technology, which I guess is good. If you think that sort of tech is good for us. Sometimes I have deep doubts about that. Certainly makes it easy for the government to keep track of us all. 😮😮😮
Joe Gavin: I also agree about Eberhard Rees…he was an unsung hero. You were very diplomatic here: Werner Von Braun was charismatic, yes, but I did not know anyone (and we had several Operation Paperclip Scientists living in my hometown area) who seemed to have respect for Von Braun as a scientist…or as a person. My father seemed to despise him as the Nazi he was, but I’m sure he kept these thoughts to himself..I only sensed this from him. I don’t think many people knew my father was born in Germany in 1919 and emigrated with his widowed mother to NYC when he was 2yr old. He was a naturalized US citizen, and yet his mother (and uncle & aunt who lived with him in their Brooklyn apt) had a house rule: only German was spoken inside the apt. He was also taught how to read & write in German. My father was the most patriotic person I’ve ever met, and when he graduated with Joe Gavin with a BA & MS in aeronautical Engr on May 28, 1942 (I have a Boston Herald newspaper photo of Joe Gavin & my dad, Rudolf W Hensel taken right after the graduate program had ended), dad ended up being an officer in the USAAF & was sent to work at Wright Field during & immediately after WWII. He, like Joe Gavin, also met Orville Wright, who lived in Dayton at the time (apparently dad & Orville took the same trolly to Wright Field each morning). And, my father spoke English with absolutely no accent…the only accent I ever picked up from him was a bit of a Boston accent I assume from his MIT days. He never wanted us children to know that he could read, write, speak German. It was quite by accident that I discovered this in 1968. I’m quite certain now that his ability to do this was helpful when our GI’s were finding jet & rocket testing facilities inside Nazi Germany in Spring, 1945. My dad was sent over there to gather up as much testing equipment (esp wind tunnel related materiel) for the USAAF & have this all shipped back to Wright Field. Pretty sure dad 1st met Dr Bernhardt Goethert when he was on the ground inside Germany in 1945..As well as other German scientists. 👉 Dr “Doc” Bernhardt Goethert is another unsung hero of that era as well. He was the most knowledgeable scientist in all things related to wind tunnels at the time…the world just didn’t know it yet. Doc Goethert & several other German scientists were in the 1st group of Operation Paperclip scientists sent to the US (Werner Von Braun & his group were actually sent to the US earlier under “Operation Overcast”. The name of this project was changed to Paperclip after members of the US press started to find out that German POW’s were being brought to the US & allowed to work with US scientists…whoops!). Dr Bernhard Goethert went directly to Wright Field & worked with my dad, quickly figured out the resolution to some technical issues with the 10ft wind tunnel there, & he, my dad, and my mother (who worked for “Doc” & 3 other German scientists @ Wright Field) became lifelong friends. Dr Goethert & my dad ended up designing what would become the Propulsion Wind Tunnel (PWT) Facility at AEDC (near Tullahoma, TN) & his family & mine were already friends before I was born. Doc Goethert went on to start UTSI (University of TN Space Institute) & was its 1st director. One of his sons, Winfried Goethert, also a scientist, was also later a director of UTSI. It is sad that my father felt that talking about himself was “bragging”. I could never get him to talk about what he did before, during, & after WWII..even though those projects were long de-classified. I assume “classified” to dad meant “classified to his grave”. Thank goodness his college buddy Joe Gavin Jr was OK doing this oral history! And I’ve been able to ask other children of aeronautical engr’s of that amazing era about what their fathers (or mothers) did & then they tell me a few things about what my dad did in relation to the Space program. Many thx to the kind folks at MIT who did this oral history with the “Mr Gavin” from my 1960’s/early ‘70’s childhood, & posting it on RU-vid. I am eternally grateful.❤ Just want you folks to know that both Joe Gavin & my dad “Rudy” lived to age 90, & died within mos of each other. Of the 4 children of “Rudy” only 1 of us (me) went on to become an scientist, & although my field of science was different from my dad’s, I certainly would have enjoyed hearing his stories & reading his academic/published papers (even if I don’t like physics that much 😂). I’m quite certain that Joe Gavin & my dad both were both chosen to attend Theodore von Karman’s very 1st class in “Jet Propulsion” in 1943/44 (it later was published into a textbook). I know dad got his PE degree at CalTech at about 1946, and he also worked for GALCIT in Pasadena starting in 1947. With Doc Goethert’s encouragement, Dad, mom & my 2 older bros moved to middle TN in 1953 to take over the role of chief of PWT at AEDC from “Doc”. Looking back through all the photos & documents of my dad’s, I’m not completely sure my parents wanted to leave Pasadena, CA (appears they had just built their dreamhouse in 1951-53). But, nonetheless, I was very happy growing up in the countryside of Middle TN with some amazing people and beautiful waterfalls, caves, & woods to explore. We kids of these aeronautical engineers were blissfully unaware of what our fathers were doing…except it all had something to do with the Space program. I also remember my dad & the rest of us watching the TV reports very intently during Apollo 13 (I’m sure dad must have known his friend Joe Gavin was sweating out/working out a solution there, but he never breathed a word of this to us). I know Joe & Rudy have been having fun kidding around with each other for the past 14 earth yrs in Heaven, just like I remember them kidding around at our dinner table in TN. Of course they never talked about their work..Joe Gavin just knew how to get my dad (a dry humor guy) to lighten up & riff with him. It was easy to understand how they must have enjoyed being students together & doing their Masters Thesis at MIT together..
The “Rudy” Joe Gavin refers to at 13:23 was my dad. Now I finally know where my dad was & what he was doing when he heard about Pearl Harbor! I just knew Joe Gavin as “Mr Gavin” when I was a kid. He’d fly to our home in TN every once in a while..early 1960’s - early 1970’s, dad would pick him up at the Nashville airport on a Sunday night. He’d stay with us through Fri morning & I assume dad drove him back to the Nashville airport Fri afternoon. I noticed Mr Gavin would always drive into work with my dad during each weekday. I just thought my dad was giving him a lot of tours at AEDC?? 😂 We kids knew never to ask any questions about my dad’s work…it was all classified then.
Sometimes I miss working at a call center for a utility company. Sometimes you would get a caller with a soft voice that just triggers the brain. It was so nice.
This is exactly what asmr should be not a bunch of women stripping half naked and making weird alien noises with their mouth and stupid whispers that stuff feels so forced and sexualized I like genuine unintentional asmr
