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.

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.
Interpretation
Science needs both a solid foundation and a structured plan to be effective.
Dmitri Mendeleev emphasizes the importance of both material resources and a well-thought-out plan in the pursuit of scientific knowledge. A plan without the necessary resources is just an unrealistic dream, while having materials without a strategic approach leads to wasted effort. Therefore, effective scientific progress depends on the harmonious integration of both elements.
In practice
This quote can be used in a scientific conference to underline the importance of planning in research projects.
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.
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.
Every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded.
Contaminated water is not a problem limited to Flint. Think of New Jersey, where school fountains were found to contain unsafe levels of lead. Or the EPA's 33,000 superfund sites, which are highly-polluted areas that require long-term clean-up operations. The problem is so large that it feels insurmountable.
At the heart of science is an essential balance between two seemingly contradictory attitudes-an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense.
If others would but reflect on mathematical truths as deeply and as continuously as I have, they would make my discoveries.
I have experimental evidence that time travel is not possible.
Science tells us more and more now that there is a strong connection between emotional well-being and health outcomes, and that you can proactively cultivate emotional well-being through relatively simple practices like sleep, social connection and meditation.
