Henri Becquerel observed that uranium salts emitted radiation that could pass through opaque materials. This led him to question what process was causing this radiation to be emitted from the uranium salts.
When Henri Becquerel discovered that uranium salts could produce images on photographic plates without exposure to light, he began questioning if the radiation emitted by uranium could be responsible for this effect. This observation led him to further investigate the properties of uranium and its ability to emit radiation.
The fogging of the photographic plates that Becquerel observed in 1896 was caused by the emission of invisible, penetrating radiation from the uranium compound he was studying. This radiation interacted with the photographic plates, causing them to become fogged or exposed. This discovery ultimately led to the further investigation of radioactivity.
The statement "the damage at this scene was caused by an explosion" is an inference, as it is deduced from the evidence present at the scene rather than being a direct observation.
Change in state: One observation would be a change in the physical state of the substance, such as from solid to liquid or gas. Reversibility: Another observation might be that the physical change is typically reversible, meaning the substance can return to its original state by reversing the process that caused the change.

Radioactivity was discovered during 1896 by Henri Becquerel, who was a French scientist when he was working on phosphorescent materials. Other research was done by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others afterwards.

The angular distance of the horizon below the plane of observation caused by the curvature of the Earth's surface is called the dip angle.

The Scientific Method: observation, hypothesis, experiment, verification, peer review.
Change in state: One observation would be a change in the physical state of the substance, such as from solid to liquid or gas. Reversibility: Another observation might be that the physical change is typically reversible, meaning the substance can return to its original state by reversing the process that caused the change.
<Novanet> observation, inference!
What caused you to ask that question
I'll answer your question with another question. You're kidding me right? Enslaving a human being for the gain of another is completely immoral and I cannot yet wrap my head around as to why humanity let things like slavery and genocide exist.
