Kind of a bad day for it to be playing "Pop goes the weasel" then....

"A weasel shut down the world's most powerful particle smasher when it wandered onto a 66,000-volt transformer and caused a short circuit, Europe's physics lab CERN said Saturday."
...
"the weasel, which did not survive its high-voltage encounter."

No kidding.

I'm pretty sure it says somewhere in the manual not to use a weasel as a resistor.

Darn critters... I've had to shell out a four figure sum to repair all the damage they've done in the engine compartment of our cars over the last years... Somehow ignition cables, cables in general and coolant hoses seem to be very tasty to them, at least the Ford ones. Our neighbor with his BMW hadn't had any problems with them so far  |O

It's probably  a stone marten, but I guess we will never know for sure.

Ford is using IIRC a soy based plasticiser in the cabling and the synthetic rubber. BMW is using a different plasticiser which is based on a petroleum product, along with using a different sleeving which is not as attractive looking, unlike the Ford tape wrap.  Try using some pepper spray in the engine compartment, renewing it monthly, and remove any loose leaf litter and trees from around the car.

Grandpa had issues with mice, they ate his Toyota. His cure was to fill the garage with bowls of Finale liquid and pellets for them to drink. The heat dried out the bodies pretty fast, so not much smell.

It indeed is according to CERN people, see meeting notes (https://indico.cern.ch/event/506407/contributions/1184968/attachments/1265776/1873815/LHC_29042016.pdf), page 11 "Cause: short circuit caused by fouine on 66kV transformer in point 8".

They even had a picture of the (charred) thing and some pictures of the connections damaged by arcing but it seems that somebody probably have insisted those to be removed from the slides.

CNN also lets us know that 1KV is "1000V of energy"...

One of my son's favourite books right now is about weasels trying to build a machine to take over the world. Definitely sounds suspicious.

Am I the only one who perpetually sees "Large Hardon Collider"? Every time I see a story about the LHC I snicker to myself like a 12 year old. Every. Time.

You are not the only one - it has been called that in several publications. For instance, the BBC http://www.mirror.co.uk/tv/tv-news/large-hardon-collider-bbc-news-5467745 (http://www.mirror.co.uk/tv/tv-news/large-hardon-collider-bbc-news-5467745)

It's ironic that the Large Hardon Collider would be stopped by a Wicked Weasel (http://wickedweasel.com/en-ca).....  :-DD

You can tell CNN that you routinely can build up 25 kilovolts just by rubbing a balloon on your hairy head. That's 25,000 of "energy" at your finger-tips, ready to fry a weasel with that?  :-DD

Never occurred to me.  But I have a hard time seeing a Harmon Kardon brand product without thinking Karmon Hardon.

Your signature...

I wish to God these calculations had been executed by steam!
C. Babbage

...reminded me of this quote:

On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Weasel shuts down Hadron Collider

sounds like "terrible design shuts down Hadron Collider".

Or more accurately, incompetent people behind that terrible design shuts down Hadron Collider.

Unfortunately, those people are too man up to admit their own faults and have to point fingers at that poor weasel.

Even worse, the public bought that finger pointing.

Sooo... everything you've ever designed has no possible failure modes because it was flawlessly designed and constructed for every possible event with unlimited budget, time, space and resources?
