Yeah, except it's to protect children from putting a knife in the socket (and touching the knife... barefoot... lethal.)

Ah yes, I remember the evening my brother shoved a wire U nail into an outlet. Not only was it shocking but he got a heck of a burn. Guessing he was maybe 4 or 5 years old. He never did that again and gained a whole new respect for electricity.

I had an experience like that at my 6 y.o. Got respect for it as well.

I was a true scientist. I had to repeat the experiment a few times before I gained confidence in the results.

I missed that stage as the only receptacle in each room on the ceiling.


but I did experiment with the lamp socket a few times before I gained confidence in the results.

 

V=I/R, P=V*I

... then 0-Ohm resistor came along...

 

then 0-Ohm resistor came along

0 does not equal 0. It is just the lowest we can cheaply make.

Oh, and don't get me started about fire. I still haven't learned my lesson.

Sometimes, I'm amazed I survived childhood. Or adulthood, for that matter.

Edit: I can still remember the day when I discovered that thingy you push down in the armrest of the back seat of the car. After a while it would pop up. You could pull it out, and it would be all red and glowy and pretty.

Fun times!

 

I was about 5 or 6 when I did experiment with putting my finger in an energized light bulb socket.
Still remember it vividly, and felt there was no particular reason to repeat the experiment.

Yebbut, the light socket is only one of the many variations of the experiment. Gotta test the variables!

 

It's pretty deep, seems the field actually is real, not just apparent (which is what I kind of thought). I'd like to study it more, get a handle on the tensor representation of the thing which it seems is powerful and elegant.

I understood tensors once upon a time when I took "Strength of Materials" and encountered the stress tensor in I-beams. That was 59 years ago so my memory is just a wee bit foggy.

 

"Get a degree in engineering and make the big money."
For the last two decades I have been making 75 to 100/hour. USD Working my hours and days. Not traveling much and doing much from home.
One rental property needs a couple hours to a day of "handyman" work. (small town USA) I called an agency and they charge $140/hour for a handyman, and he gets 1/2 the money. On the side I do electrical, plumbing, heating, for way too little. I need to rethink life. I find tradesmen charge as much as an engineer makes. (no agency)

My first two years after university I designed and installed robots that replaced assembly line workers. The engineers made less money than the line workers. They were union and I was not.

What's bizarre is that British sockets already have built-in shutters (and have done since 1947), but still someone's managed to make money selling protective covers.

 

Aether was a myth, selenites were a myth and mermaids as well but most of the above is simply things that someone did not understand well.

 

Anti-Static cordless wrist straps are not just myths, they're frauds:

I didn't get a shock, but it was an explosion because I was "trying to charge my RC car" with, you know, a lot of available energy.
That explosion was so fast I don't remember, I just remember my parents coming to me to see what happened. Then my dad, in the subsequent days, turned that outlet off, because it was in my room. But I didn't get to play again with the outlet until I made a course of electricity in my 14-15 years old.

Attached is the graph over the years of how many minimum wages, on average, people that are graduated (higher), and people who just have high school (lower), earn per month in Brazil. Source: an organization of the government, the IBGE.
I don't want to get political, but just for info, there were both right wing and left wing governments, but both following neoliberal ideas.
I also thought that I would earn a lot, but when I get to graduate, 6 years ago, it was already over.

I didn't earn a lot (compared to billionaires) but I lived a lot doing what I loved.

A damn good tradeoff IMO. No regrets.

Sorry to ask, but what did you work with?
