No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.

We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
Interpretation
Mendeleev suggests that there are many undiscovered elements that will likely be found in the future.
In this quote, Dmitri Mendeleev expresses his belief in the potential for future discoveries in the field of chemistry, specifically referring to elements that share properties with known elements such as aluminum and silicon. He emphasizes the importance of scientific exploration and the anticipation of new findings that can expand our understanding of the natural world.
In practice
In a science class discussing the periodic table and the potential for new elements.
No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.
The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Believe only in that.
It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man - social and political - and to the entire universe as a whole.
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
The edifice of science not only requires material, but also a plan. Without the material, the plan alone is but a castle in the air-a mere possibility; whilst the material without a plan is but useless matter.
If you aren't confused by quantum mechanics, you haven't really understood it.
My ambition was to bring to bear on medicine a chemical approach. I did that by chemical manipulation of viruses and chemical ways of thinking in biomedical research.
The trouble is that the hockey stick graph become an icon and deniers reckoned if they could smash the icon, the whole concept of global warming would be destroyed with it.
The fossil reserves that have already been discovered exceed what can ever be safely used. Yet companies spend half a trillion dollars each year searching for more fuel. They should redirect this money toward developing clean energy solutions
The future belongs to Science. More and more she will control the destinies of the nations. Already she has them in her crucible and on her balances.
It was one time when people thought the value of the fine structure constant was important. Now of course it's still important, of course, as a practical matter,but we now know that the value it has is a function, that in any fundamental theory you derive the fine structure constant as a function of all sorts of mass ratios and so on and it's not really that fundamental.
