What is the newest installment of 'Random Thoughts' on Physics Forums?

In summary, the conversation consists of various discussions about documentaries, the acquisition of National Geographic by Fox, a funny manual translation, cutting sandwiches, a question about the proof of the infinitude of primes, and a realization about the similarity between PF and PDG symbols. The conversation also touches on multitasking and the uniqueness of the number two as a prime number.

Norfolk Southern continuing cleanup from Ravenna Township, Sandusky derailments
https://www.yahoo.com/news/norfolk-southern-continuing-cleanup-ravenna-110301995.html

The route goes through East Palestine and is believed to be the same route taken by a train carrying hazardous material that derailed there, causing an environmental catastrophe on Feb. 3.

The Norfolk Southern train derailment site in November in Portage County, along with another that happened in October in Sandusky, still being cleaned up months after they occurred, as the railroad also scrambles to deal with the derailment in East Palestine.
The train was a general manifest, which means mixed freight as compare to a single commodity like grain, oil, automobiles, coal or containers/trailers (intermodal).
The 238-car train that derailed in Portage County was carrying a variety of freight, including 63 cars containing unidentified hazardous materials, according to a mandatory accident report Norfolk Southern filed with the Federal Railroad Administration. The railroad previously said 22 derailed cars were predominantly auto racks that carry vehicles and hoppers holding rock salt. About 300 tons of rock salt piled from three cars, according to the report.

In the past, 238 cars would have been two or three trains. Over the past decade, the six largest (Class 1) railroads have been increasing lengths of trains in order to reduce the number of crew required to move the freight. Two people (engineer and conductor) and sometimes 3, if there is a brakeman, operate a train in the lead locomotive. Locomotives are connected (MU'd) at the front, but some locomotives may be placed in the middle and/or rear of the train (as distributed power units, DPUs) to distribute the driving force. Use of DPUs depends on length of train and ruling grades on a route.

The Norfolk Southern report, which still has to be verified by the Federal Railroad Administration, said the primary cause of the Ravenna Township wreck was "buffing or slack action" and "train make-up" around the 121st position in the train as it was traveling at 35 mph down the track that evening.
Something went terribly wrong if "buffing (pushing) and/or slack (pulling) action" or "train make-up" lead to the derailment. That is an operational issues as opposed to equipment/track failure.

How dangerous train derailments affect communities like East Palestine, Ohio

Four rail-borne risks moving through American communities​

https://www.yahoo.com/news/four-rail-borne-risks-moving-210000159.html

There is actually a lot more than 4, but the 4 are high tonnage, i.e., hundreds or thousands of tons (about 100 tons per carload). During grad school, I did a brief summary of chemical commodities moved through the university area (the railroad bisected the campus) because the local Transportation Institute had no such list. I just happened to watch trains and particularly tank cars moving through the area. For three years, I lived one or two blocks from the rail line.Edit/update: Video shows plastics from two hopper cars burning.

There's a pie chart in Lame Jokes somewhere that shows the percentage of dropped bolts that are on the floor in plain sight versus disappeared into some other dimension never to be seen again.

My sock is not lost, though, it is merely no longer a simply connected domain.

One of my organic chemistry professors is a gangster.
Once before a lab, he told us that certain chemicals might be missing from the stock after a break in. He then went onto comment that they had apparently only stolen some commonplace solvents, and that if he was to do it, he would probably have picked some narcotics precursors -- in the most monotone and non-jocular voice ever.

Recently, I've been struggling with an exam I had to retake, and as a result been falling behind on school work. Told him that I'd have trouble turning in assignments on time until then. He asked me which course the exam was in and when I told him, he proceeded to dang on it for five minutes saying how much of a mess the course is.

He also works with explosives.

Having other Linux users do something on your own Linux system for more than 10 minutes should break your warranty.

I swear to god, these dickheads just needed to install a few things and suddenly I have five versions of python installed and my terminal is slow.

My work computer has had my profile rebuilt at least four times in the last two months resulting in the loss of everything in AppData - wiping out all of my Firefox bookmarks, server login settings for Putty, etc. Each time that I tell the help desk that I need to "recover" my profile that was lost, they rebuild it again instead. ?:)

Yes, and I was Hell-ped again this morning. At this point, it almost seems as though someone has set a program to rebuild my profile each morning. Thankfully, today is my last day on the project and I won't have to use those computers anymore. On to better things!

I saw a commercial for a new movie and had to laugh - Cocaine Bear. It's about a bear that finds a bunch of cocaine dumped from an airplane. They need to do a mashup with the Project Grizzly movie. :oldtongue:

Maybe this should go in the "Today I Learned" thread, but apparently the movie is actually based on a true story. -- I know. A true story !?!

‘Cocaine Bear,’ a drug smuggler and the very real story behind it all.

I just found out that Nickelodeon broadcasts on Ukrainian here on free tv, voice-over. Not a bad idea, given that in Germany alone are more than 200,000 Ukrainian kids in our schools. Imagine that number, then add Poland and other countries. It is an unbelievable human tragedy this monster has brought across Europe.

Where can I buy Orange Vanilla Coke? It's not anywhere, despite being a huge release after commercials like this one a few years ago:


It was my favorite Coke drink too. It cannot be found anymore in any major store.
