As a PhD who has tried doing home improvement projects, it’s the most believable thing in the film.

[-] MadBob@feddit.nl 28 points 2 weeks ago

Actually some of the most naïve people I've ever met were theretofore academically successful.

My fiancee has a couple degrees while I just graduated high school. She's incredibly smart but I'm definitely more street savvy. She grew up a bit sheltered.

Really?

Genuinely asking, I'm just an engineer... with very very bad grades. Passed was enough for me.

Once a professor asked me if I wanted to take the exam again because it was clear that I knew more than what I showed on the exam (a lot of 2 + 2 = 5 mistakes, I was fairly good at that and owe most of my low grades to that). I asked him if I passed, he said yes. Fuck that shit, I'm taking that grade and parading it across town, wooohoo 🥳.

As they say, a PhD is about learning more and more about less and less. Some of the smartest people at conferences I've attended legitimately risk death crossing the street.

Lol 😂, reminds me of some of the professors at uni 😂.

Some pleeb shouted at me, "I thought you were an engineer!" And I shouted back, "A software engineer!" while I hammer a nail with my shoe.

[-] captainlezbian@lemmy.world 5 points 2 weeks ago

I’m a regular engineer and yeah I pull such shit. Listen, there’s a reason I tell everyone not to do what I do.

A high voltage electric fence. At some point even standing in front of the thing is enough.

[-] SzethFriendOfNimi@lemmy.world 44 points 2 weeks ago

Air only has so much resistance itself. High enough voltage and the closest path to ground is where the charge will go.

Just like with Lightning

My arm once got pulled into an electric fence when I was a kid and I couldn't stop getting shocked until someone physically pulled me away. It was more of a self-control issue than accidentally bridging the gap.

That was the day I learned that some pain can be pleasant. The owner of the property didn't seem as pleased with my discovery as I did. He had to shut off the fence and yanked my arm away and then told me to go explore my perversions somewhere else. I was too young to understand the word "perversion," and I'm now eternally grateful to that poor unprepared rancher.

[-] bjoern_tantau@swg-empire.de 11 points 2 weeks ago

For more fun form a chain with other people and be the furthest from the person touching the fence.

At approx 3kV/mm, you would have to be pretty close to a 10kV fence.

Humidity plays a big role as does the frequency that the fence is running on. But you would be pretty safe standing a meter away, on that dry sunny day in the picture.

Also above a point, the high voltage causes the conductors to buzz.

[-] frezik@midwest.social 12 points 2 weeks ago

Dry? It was a carribean island, right? Probably humid as fuck.

With enough voltage, everything is a conductor.

[-] Grumpy@sh.itjust.works 9 points 2 weeks ago

I have a 10KV electric fence. 5KV to 15KV is typical electric fence voltage in a farm or bear prevention fence. Can't feel a thing unless you actually touch it.

They are also not lethal. Very low current, just very high voltage. So it only hurts like fuck, but won't kill a human, cow, or any other mammal that touches it.

[-] Semi_Hemi_Demigod@lemmy.world 7 points 2 weeks ago

They can't kill you, but I know from experience that they can knock you out for a bit if you get shocked through your head.

This is why you should never try to remove a tree from a power line yourself.

Electricity always takes the path of least resistance back to the source. A tree, and possibly your body, may end up being the "path of least resistance".

You won't know if YOU are the path of least resistance or it the line is even energized until it's too late.

[-] sugar_in_your_tea@sh.itjust.works 6 points 2 weeks ago

Yup, this is why I shoot fallen tree limbs with a shotgun.

Just because you're very good at one thing doesn't mean you're good at another. Sometimes the further you go down one path, the less you know about everything else.

Clearly his PhD is not in electrical engineering or biology

[-] The_Picard_Maneuver@lemmy.world 35 points 2 weeks ago

It's actually a PhD in trombone. Someone misheard it one time, and nobody has ever thought to follow up.

"Oh, Alan? Yeah, he has a doctorate in bones or something."

IIRC, he was messing with the kids and knew it was off because the lights were off. He proceeded to put his hands on it and convulse wildly as a joke.

At 10kV, a random stick would be all it takes to start an arc. He knows what he's doing.

True, True… Hay who thought it was safe to run 10,000V Wire through a flammable overgrown jungle?

Wet wood from the ground is probably a better conductor than dinosaur scales

[-] SpaceNoodle@lemmy.world 8 points 2 weeks ago

Did dinosaurs have scales?

[-] Evil_Shrubbery@lemm.ee 23 points 2 weeks ago

I dont think so, bananas are a relatively new thing iirc.

I don't remember the scene, but personally I'd test an electric fence with a nonconductor. You'll probably get some sparks but won't die. You do you, ppl in this thread.

[-] Bertuccio@lemmy.world 20 points 2 weeks ago

I invite you to touch an electric fence with a stick then.

[-] Honytawk@lemmy.zip 12 points 2 weeks ago

Is his PhD in Electrical Engineering?

[-] Aceticon@lemmy.world 10 points 2 weeks ago* (last edited 2 weeks ago)

Well, I have an EE Degree specialized in Digital Systems - pretty much the opposite side of Electronic Engineering from the High Power side - and I would be almost as clueless as that guy when it comes to testing a 10,000V fence for power.

On the other hand I do know a lot of interesting things about CPU design ;)

Even throwing a metal pipe against it won't do anything. Electric fences have one electrode in the ground, and that's how your body makes the circuit. If they had run and jumped onto the fence, then jumped off on the other side they would have been fine with the fences still active.

Source: I've set up an electric fence and been shocked multiple times, once through my head.

He probably wanted to prevent significant arcing by using a higher impedance test apparatus due to the high voltage.

Yep. Very domain specific knowledge but couldn’t pour piss outta a boot with the instructions on the heel.
