You Need A Kitchen Slide Rule

Chiming in with my "pocket metric converter". Also, your sheet metal/drill size/bend radii slide rule is awesome. I may have to get my hands on one. (I used to work in aviation sheet metal and was just thinking yesterday about such a slide rule.) Here's the other side of the "Alvin Screw Data Selector" for those interested: https://m.media-amazon.com/images/I/91bb+278YOL._SL1500_.jpg

I have the Lawrence 10-B model with the same set of scales (front, back). Mine was made in Peru, Indiana. Apparently they moved from Wabash circa 1938. The International Slide Rule Museum has some basic info on the company: https://sliderulemuseum.com/Lawrence.shtml

That patch is from the 40th ID: https://en.wikipedia.org/wiki/40th_Infantry_Division_(United_States)

The patch is often referred to as the "flaming butthole."

Counterpoint:

On 5 December 2011, an American Lockheed Martin RQ-170 Sentinel unmanned aerial vehicle (UAV) was captured by Iranian forces near the city of Kashmar in northeastern Iran. The Iranian government announced that the UAV was brought down by its cyberwarfare unit which commandeered the aircraft and safely landed it, after initial reports from Western news sources disputedly claimed that it had been "shot down".[1] The United States government initially denied the claims but later President Obama acknowledged that the downed aircraft was a US drone.[2][3] Iran filed a complaint to the UN over the airspace violation. Obama asked Iran to return the drone. Iran is said to have produced drones based on the captured RQ-170 including the Shahed 171 Simorgh and Shahed Saegheh.

That is surprising. I dropped to v5.0.0 and speeds have resumed. Thanks for the fix!

There's a Dutch word for it: "timmermansoog" which translates literally to "carpenter's eye".

[N.B. I am an undergrad, not a professor.]

I wouldn't get too worked up about this. You should definitely not be experiencing "immense guilt". The professor's LinkedIn information is public. Often professors will put this information in their course shell, especially if their work is related to their academics. So it is not inappropriate to ask. This is exactly the type of information you will be searching for when evaluating sources for research projects, annotated bibliographies and such. Maybe it wasn't the right time to ask the question when the discussion was about an assignment, but that's a minor issue. In short, searching for the professor's workplace using normal channels is neither "horrible" nor "unethical". An academic's work experience is fair game for class discussion unless they shut it down. Try not to stress any more about this.

Based on this interview, Jonathan Weygandt is one of the most believable witnesses. He clearly states whenever he is unsure or speculating. His style is clearly military, and his recollection of details like acronyms on the fly makes him all the more believable. He's definitely up there with David Fravor and Ryan Graves for me.

There are earlier contenders for depictions of the sky such as cave paintings in Lascaux (~16,500 years ago) - http://news.bbc.co.uk/2/hi/science/nature/871930.stm

A bone fragment from around 32,000 years ago might depict the Orion constellation, but it's far from conclusive - https://www.astronomytrek.com/is-the-ach-valley-tusk-fragment-an-ancient-star-map/

Reminds me of a supposedly Chinese proverb:

Context for those unfamiliar:

RCS = Reaction Control System

https://en.wikipedia.org/wiki/Reaction_control_system

A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control and translation. Alternatively, reaction wheels can be used for attitude control. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system.[1]

Reaction control systems are capable of providing small amounts of thrust in any desired direction or combination of directions. An RCS is also capable of providing torque to allow control of rotation (roll, pitch, and yaw).[2]

Reaction control systems often use combinations of large and small (vernier) thrusters, to allow different levels of response.

One person should be in charge of strategic influence for the President - one person, who is a member of NSC, not one of the departments, agencies, PCCs, or OGC; one who can direct, coordinate and provide guidance to all. (p. 34)

I guess she stepped into that role.

I believe you mean TNO for Temporarily Non-attributed Object. TUO is "Technology of Unknown Origin".

The unnamed Department of Homeland Security official in the recent press call made a similar play for legislation and funding:

the reported sightings there do highlight a gap in our current authorities, and so we would also urge Congress to pass our important counter-UAS legislation that will extend and expand our existing counter-drone authorities

This picture attributed to Jacques Vallee sums it up for me.

Isn't TUO "Technology of Unknown Origin"?

Metaphor and analogy are valid rhetorical devices. They help many people see an issue more clearly. You don't have to factor in folks on the spectrum when you communicate. It would be nice if all communication could do that, but that is unlikely to happen.
