I Can Meet with Dead Scientists

Chapter 441 - 222 The Truth Comes Out_3

I should have realized at the time that flashlights existed in this era.

In summary.

Now that Will explained it, everything became clear.

Why flashlights exist, why I felt a sense of dissonance, it’s because...

The timeline of this world is not the one inferred after the 1665 Dungeon.

But a world that was also influenced by the letter I previously sent to Little Niu on the basis of the 1665 Dungeon!

Think about it.

According to normal historical development,

it would be 1808.

Marius would only discover the phenomenon of light polarization then.

Subsequently, in 1818, Poisson’s spot would officially be discovered.

Poisson’s spot can basically be considered the cognitive limit of Classical Physics in optics—add some mathematical definitions from Faraday and Maxwell at most, and then it’s the photoelectric effect 80 years later.

As for Little Niu now, he advanced the discovery time of Poisson’s spot by a full 140 years.

Though there was Thomas Young’s interference experiment in between,

but with Little Niu’s wisdom, he probably had some other approach to fill this cognitive gap.

And to study light, naturally, a light source is needed.

Thus, in long-term research, Little Niu discovering that metals emit light when heated almost became an inevitable outcome.

Admittedly.

Little Niu’s research focus was not on this, it could only be considered a minor branch.

But some theories or ideas he left behind could allow later generations to easily invent the flashlight—it’s merely a matter of who would be the lucky one.

In other words.

This is a world where the pace of development has been disrupted twice, a Dungeon where scientific history underwent significant changes.

For instance, the inventor of the electric lamp is neither Edison nor David, but Dylan Wilson.

The inventor of the flashlight is also no longer Conrad Hubert, but Greenwood McTominay.

That’s just for one appliance.

What about the theoretical world?

What about the global landscape?

Don’t think that Little Niu is only a physicist; with Little Niu’s wisdom combined with Xu Yun’s hints, his influence could not possibly be limited to the field of physics.

After all, before the emergence of microphysics, macro physics and real life were almost inseparably connected.

What kind of changes could the twice-future-altered Little Niu bring to this world?

Xu Yun really can’t judge.

At the same time.

He suddenly thought of another matter:

If such a large change occurred in the Dungeon’s background, would Adam Hopkins still exist?

After all, he is a pure theoretical expert.....

He probably will..., right?

"By the way, Luo Feng, Will and I only brought one tent this trip, and it can’t fit three people." "So tonight you have to sleep in the carriage, is that okay?" Thomson and Will took a two-wheeled carriage, looking quite ordinary, with nothing remarkable. It could seat two inside, and the outer antechamber where the coachman sits could also seat two, totaling four. The space in the compartment minus all kinds of packages isn’t large, ** is impossible, you’d probably have to sit to sleep. But fortunately, Xu Yun’s business travel experiences in his past life were quite abundant, having experienced green trains and youth hostels, his adaptability was barely passable. So he quickly accepted the reality of having to sleep in the carriage and replied, "No problem, Mr. Thomson, I’d be grateful to have a place to settle." Thomson nodded slightly, picked up the package beside him and began rummaging through it, saying, "At night, there’s no light outside the carriage, and there are lots of dead branches and stones around, so if you need to relieve yourself at midnight, it might be a bit troublesome." "So I’ll lend you something; you can use it for lighting, just return it to me tomorrow." Xu Yun instinctively nodded. In this era, items used for lighting during toilet breaks certainly won’t be oil lamps or torches, as they are too cumbersome to handle. So it would unsurprisingly be matches or tinderboxes? However, to his surprise. A moment later. Thomson pulled out something black, thick, and hard from the bag at his crotch and handed it to Xu Yun, "Found it." Seeing Xu Yun a bit flustered, Will at the side explained, "Mr. Luo Feng, the usage of this item is very simple, just hold it and exert force up and down." "Like this." Saying that, Will took the item, pressed a button, and slightly pushed it. The next second. A strong light shot out from it, directly hitting the opposite tree stump. Clack! Will pressed the switch again, and the light vanished. He gently tossed the item in the air, smiled at Xu Yun, and said, "This thing is called a flashlight, quite expensive, an average household won’t see it." At this moment. Looking at the proud Will, Xu Yun really wanted to say to this country lad: Of course, I know this is a flashlight... but the problem is..... why is it appearing at this time???? You have to know. Judging from the previous situation, the current time should be around 1850. At most, with slight fluctuations, between 1849-1851. It’s general knowledge even a primary student knows: in 1879, Edison invented a long-lasting electric lamp. But at this time, Edison is only three years old... Not to mention that a flashlight only came after the light bulb, invented by Conrad Hubert in 1938. In other words... in this Dungeon, the invention of electric lamps was nearly a hundred years ahead of the original history! But according to what Xu Yun did in the 1665 Dungeon, theoretically, it shouldn’t result in this outcome. Be it the binomial simplification or the elasticity formula snatched from Hook, none of this should be related to flashlights, involving other areas instead. For example, this era possibly featuring refracting telescopes, spring dynamometers, inflatable dolls sorts of things is likely. The flashlight requires one thing: electrical knowledge and dry cell preparation, which involves electrode plate issues. This doesn’t really have much to do with Little Niu... As the saying goes. Joking is not nonsense, adaptation is not random alteration. Even deduction must follow basic logic. Fifteen minutes later. Everyone finished their meal. Thomson went to the river to wash the dishes, and Xu Yun and Will stayed at the site setting up the tent. With Thomson disappearing for a while, Xu Yun couldn’t help looking at Will and asking, "Mr. Will, do you know who invented the flashlight?" "The inventor of the flashlight?" Will was slightly stunned, then immediately answered, "His name is Greenwood McTominay, a British." Xu Yun was silent for a moment and then asked, "What about the electric lamp?" "Dylan Wilson, a French scientist." Greenwood McTominay, Dylan Wilson.
