Could be a language barrier. The second step calculates Specific Gravity in English.

Reply to comment by Kozzinator in How do they know what the inside of the earth is made of, along with the internal temperatures? by Kozzinator
If you think that's cool, look up how they use spectroscopy to determine the composition of other stars and planets millions of lightyears away.

Reply to comment by BeneficialWarrant in Maybe a simple question, but why are proteins structural? by danrthemanr
Not to mention the proteins have different forms in different chemical solutions. So pH, temperature and catalysts can all modify the proteins in different ways. Not to mention proteins can inherently interact with RNA allowing for complex bio machinery basically attached to written code.

Reply to comment by [deleted] in I recently learned that humans can smell rain / petrichor (ozone and geosmin) better than sharks smell blood, now considering we don't have any extra hyper specific olfactory organs like some other animals do, how do we achieve this level of detection? by Corvuscoraxaphro
So what you're saying is that a person could literally smell the bulbs deteriorating before any other noticeable deterioration actually happens?
Would this be like me bringing the milk out of the fridge and leaving it on the counter and with less than a minute start to smell it going bad?

The air wouldn't contribute anything to the weight so it shouldn't matter

> Divide the mass by the volume and you have the volume mass of the sponge.
This calculates the sponge’s density. Mass divided by volume. Nothing further needed.
> Divide it again by the volumic mass of pure water (1000kg/m3 or 1kg/L) and you obtain its density.
This is totally useless and wrong.

Super glad someone mentioned the Hall Effect. Wrapping your mind around what really happens is nuts.
