Hilariously, light is an electromagnetic wave.

So, yes, we can see electromagnetic waves.... Just, only a very small segment of them.

How wrong he was. Now we use EM daily for everything.... Communicating via Wi-Fi, listening to music in the car (FM broadcast), or via Bluetooth and using LTE... Even heating our food. Not to mention medical applications like X-rays...

There's a shitload of stuff we use EM for without even thinking. It's all around us, all the time, like the matrix. I love EM science.

This goes to show you that, just because someone discovered a thing, doesn't mean that they have any idea what to do with that discovery, or that the discoveries end there....

Before, reality was just what humans could touch, smell, see, and hear, but after the publication of the charged electromagnetic spectrum, we now know that what we can touch, smell, see, and hear, is less than one-millionth.

If only he knew his discovery would lead to the worst car rental company he problem wouldn't have published

The germans are really something else, what innovation hasn't sprung from their imagination?

[–] [email protected] 29 points 11 hours ago (2 children)

We stand on the shoulders of giants etc etc. But it seems odd to me that they wouldn't think about using this for communication at least.

[–] [email protected] 12 points 3 hours ago (2 children)

It's not always immediately obvious to what end you can use a new innovation. For instance, the Romans discovered and built a steam engine. But nobody connected the dots that it could be used to power a train.

To me, it showcases the main reason why we need to collaborate. Only together, we can exponentially increase the potential of everything we build.

Herons steam "engine" had no power whatsoever and was not scalable. And even if it would have been scalable, they had had no fuel to drive it.

[–] [email protected] 1 points 1 hour ago

No fuel? All you need is something that makes a fire. And it is not like crude oil wasn't know to people back then.

If the invention had been further explored it is entirely reasonable to assume people could have invented a "practical" steam engine 2.000 years ago. All it would have needed is fixing the steam exhaust and have it drive a shoveled wheel.

Imagine industrial revolution Roman Empire, thank fuck they didn't connect the dots.

https://en.m.wikipedia.org/wiki/History_of_radio

By August 1895, Marconi was field testing his system but even with improvements he was only able to transmit signals up to one-half mile, a distance Oliver Lodge had predicted in 1894 as the maximum transmission distance for radio waves.

I suppose beyond the engineering know how required they were looking at possible transmission ranges and thinking it simply wasn't practical, square law and all that.

[–] [email protected] 11 points 3 hours ago

This.

There are often actual limits to what can be done, and there are practical limits. Especially in the early days of a technology it's really hard to understand which limits are actual limits, practical limits or only short-term limits.

For example, in the 1800s, people thought that going faster than 30km/h would pose permanent health risks and wouldn't be practical at all. We now know that 30km/h isn't fast at all, but we do know that 1300km/h is pretty much the hard speed limit for land travel and that 200-300km/h is the practical limit for land travel (above that it becomes so power-inefficient and so dangerous that there's hardly a point).

So when looking at the technology in an early state, it's really hard to know what kind of limit you have hit.

Faraday, after demonstrating how moving a magnet through a coiled wire induced a current in the wire was asked by a visiting statesman what was the use of this.

Faraday responded, "In twenty years, you will be taxing it"

Similarly, at a demonstration of hot air balloons in France, Benjamin Franklin was asked "Of what use is this?"

Franklin replied, "Of what use is a newborn baby?"

[–] [email protected] 5 points 2 hours ago

"Mr. Franklin, of what use is this hot air balloon contraption?"

"You can take ladies up in it with a bottle of wine and a blanket and you know, they can’t refuse, because of the implication. Think about it. She's floating up in the middle of the sky with some dude she barely knows. You know, she looks around, and what does she see? Nothing but open air. 'Ahhhh! There’s nowhere for me to run. What am I gonna do, say ‘no?’"

That last bit is me when dealing with people who "aren't impressed" by today's AI.

[–] [email protected] 6 points 1 hour ago

The problem isn't the "AI". It is people praising its babbling as the solution for everything.

[–] [email protected] 3 points 1 hour ago* (last edited 1 hour ago)

I'm not impressed by today's AI and I also fully understand that the tech is going to completely upend society and will eventually be a part of our picture of utopia, or our picture of actual hell on Earth.

The people who are screaming it's wild wonders and benefits are at least as closed-minded as the people who think we're going to be able to put the toothpaste back in the tube. The actual direction this tech moves is going to be far more like the discovery of radio, in that at the time of it's discovery and early implementation, the people then had no idea the implications down the road and we're at the same point. Except the big difference and why this is contentious is that radio was far less dangerous to society broadly.

Radio was a fundamental force that always existed around us, we learned to use it the way our ancestors used rivers and waters to move goods and people. AI is completely human-made and doesn't exist without human engineering, so it's not neutral, it's a tool shaped by man to do whatever a man wants with it.

Sounds like Faraday understood the... potential.

[–] [email protected] 8 points 4 hours ago

Funnily enough, Faraday seemingly also understood that the Electric Field only possesses a potential in the absence of changing magnetic fields. Because only in the absence of changing magnetic fields, the rotation of the Electric Field is zero, and only then it has a potential.

That's a really cool Franklin quote. Visionary.

[–] [email protected] 40 points 16 hours ago (1 children)

Everything I've ever heard about Franklin makes him a boss. This is a new one.

[–] [email protected] 35 points 15 hours ago (3 children)

Here's a little known fact that is not true, which will bring some nuance to the previous anecdote, Benjamin Franklin ate babies.

[–] [email protected] 20 points 14 hours ago (1 children)

Another one that is true but sounds like an onion.

He enjoyed the company of GILFS

Because there is no hazard of Children, which irregularly produc'd may be attended with much Inconvenience.

I didn't need to know Benjamin Franklin fucks old ladies because they can't have babies, but I appreciate the honor of carrying this information.

also the idea of a genius putting a bucket on the head of a grandma he fucks and telling her to act like she's 21 is HILARIOUS to me

And as in the dark all Cats are grey, the Pleasure of corporal Enjoyment with an old Woman is at least equal, and frequently superior, every Knack being by Practice capable of Improvement.

That's my favourite part to quote.

When the lights are out. Pussy is pussy. And old pussy is often better. 😉

It's dangerously close to "In the dark a hole is a hole."

Was he the guy that started that rental car company?
