The reading of all good books is like a conversation with the finest minds of past centuries.
Rene DescartesRead
Mathematics is a more powerful instrument of knowledge than any other that has been bequeathed to us by human agency.
Interpretation
Mathematics is the most effective tool for understanding the world.
In this quote, Rene Descartes emphasizes the unparalleled significance of mathematics as a means of gaining knowledge. He suggests that among all the tools and methods developed by humans for acquiring understanding and insight, mathematics stands out as the most powerful and influential, capable of revealing truths about the universe that may be hidden from other disciplines.
In practice
In a speech about education, one might say, 'As Descartes noted, mathematics is a powerful instrument of knowledge.'
The reading of all good books is like a conversation with the finest minds of past centuries.
If we possessed a thorough knowledge of all the parts of the seed of any animal (e.g. man), we could from that alone, be reasons entirely mathematical and certain, deduce the whole conformation and figure of each of its members, and, conversely if we knew several peculiarities of this conformation, we would from those deduce the nature of its seed.
Before examining this more carefully and investigating its consequences, I want to dwell for a moment in the contemplation of God, to ponder His attributes in me, to see, admire, and adore the beauty of His boundless light, insofar as my clouded insight allows. Believing that the supreme happiness of the other life consists wholly of the contemplation of divine greatness, I now find that through less perfect contemplation of the same sort I can gain the greatest joy available in this life.
I am accustomed to sleep and in my dreams to imagine the same things that lunatics imagine when awake.
The greatest minds are capable of the greatest vices as well as of the greatest virtues.
In order to improve the mind, we ought less to learn, than to contemplate.
But like all power, there are those who want to keep it for themselves. The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations. Want to read the papers featuring the most famous results of the sciences? You'll need to send enormous amounts to publishers like Reed Elsevier.
Windmills installed around the world converting their direct current into alternating current and feeding the electric energy into the world network can harvest the planet Earth's prime daily energy income source-the wind--and adequately supply all the world's energy needs
My expertise is the space program and what it should be in the future based on my experience of looking at the transitions that we've made between pre-Sputnik days and getting to the moon.
The intelligent beings in these regions should therefore not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It is a bit like a rich person living in a wealthy neighborhood not seeing any poverty.
Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.
There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history.
