None are so old as those who have outlived enthusiasm.
Henry David ThoreauRead
The process of discovery is very simple. An unwearied and systematic application of known laws to nature, causes the unknown to reveal themselves. Almost any mode of observation will be successful at last, for what is most wanted is method.
Interpretation
Discovery is achieved through persistence and systematic observation of nature using established principles.
Henry David Thoreau emphasizes that the journey of discovery is fundamentally straightforward when one diligently applies known principles to the natural world. He suggests that with consistent effort and a methodical approach, the unknown can eventually be uncovered, indicating that the key to successful observation lies in having a structured method rather than relying solely on specific techniques or conditions.
In practice
This quote can be used to inspire students in a science class to approach experiments with a methodical mindset.
None are so old as those who have outlived enthusiasm.
Through want of enterprise and faith men are where they are, buying and selling and spending their lives like servants.
An early-morning walk is a blessing for the whole day.
Have no mean hours, but be grateful for every hour, and accept what it brings. The reality will make any sincere record respectable.
As every season seems best to us in its turn, so the coming in of spring is like the creation of Cosmos out of Chaos and the realization of the Golden Age.
That grand old poem called Winter
The general struggle for existence of animate beings is not a struggle for raw materials, these for organisms are air water & soil, all abundantly available, nor for energy which exists in plenty in the sun and any hot body in the form of heat, but rather a struggle for entropy, which becomes available through the transition of energy from the hot sun to the cold earth.
The first footfalls on Mars will mark a historic milestone, an enterprise that requires human tenacity matched with technology to anchor ourselves on another world.
The more statistically improbable a thing is, the less we can believe that it just happened by blind chance. Superficially, the obvious alternative to chance is an intelligent Designer.
If there is any kind of animal which is female and has no male separate from it, it is possible that this may generate a young one from itself. No instance of this worthy of any credit has been observed up to the present at any rate, but one case in the class of fishes makes us hesitate. No male of the so-called erythrinus has ever yet been seen, but females, and specimens full of roe, have been seen. Of this, however, we have as yet no proof worthy of credit.
Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.
The image of Stephen Hawking - who has died aged 76 - in his motorised wheelchair, with head contorted slightly to one side and hands crossed over to work the controls, caught the public imagination as a true symbol of the triumph of mind over matter.
