A Quote by Hermann von Helmholtz
You all know how powerful and varied are the effects of which steam engines are capable; with them has really begun the great development of industry which has characterised our century before all others.

It is sunlight in modified form which turns all the windmills and water wheels and the machinery which they drive. It is the energy derived from coal and petroleum (fossil sunlight) which propels our steam and gas engines, our locomotives and automobiles. ... Food is simply sunlight in cold storage.
Embedded in every technology there is a powerful idea, sometimes two or three powerful ideas. Like language itself, a technology predisposes us to favor and value certain perspectives and accomplishments and to subordinate others. Every technology has a philosophy, which is given expression in how the technology makes people use their minds, in how it codifies the world, in which of our senses it amplifies, in which of our emotional and intellectual tendencies it disregards.
There exists in nature a force which is immeasurably more powerful than steam, and by means of which a single man, who knows how to adapt and direct it, might upset and alter the face of the world.
It appears to me that one great cause of our difference in opinion on subjects which we often discuss is that you have always in mind the immediate and temporary effects of particular changes, whereas I put these effects quite aside, and fix my whole attention on the long-term effects that will result from them.
The great blessing of private property, then, is that people can benefit from their own industry and insulate themselves from the negative effects of others' actions. It is like a set of invisible mirrors that surround individuals, households or firms, reflecting back on them the consequences of their acts. The industrious will reap the benefits of their industry; the frugal the consequences of their frugality; the improvident and the profligate likewise. They receive their due, which is to say they experience justice as a matter of routine.
So far as we know, Earth is the only planet which supports life, and it is the only planet on which we can survive. Our bodies and our minds are fashioned by it. Our hearts resonate with it. There will be little joy for the human spirit if we destroy the natural fabric of Earth with nothing left to do but go shopping. When we imagine the world a century from now, when we look our great grandchildren in the eye and see them smiling back at us because they know we cared for them, we smile too!
I have been interested in the 12th century since my 20s when it was very fashionable to say of anybody with whom you disagreed, which was basically anybody over the age of 30, "One of the great minds of the 12th century", and one day I thought, "I don't know anything about the 12 century." So I started buying books, reading about it, and I discovered it was a period of great flowering, it was a Renaissance before what we think is the Renaissance, the Italian Renaissance of the 16th century.
The rich and luxurious may claim an exclusive right to those pleasures which are capable of being purchased by pelf, in which the mind has no enjoyment, and which only afford a temporary relief to languor by steeping the senses in forgetfulness; but in the precious pleasures of the intellect, so easily accessible by all mankind, the great have no exclusive privilege; for such enjoyments are only to be procured by our own industry.
In the Small group the individual can know the effects of his actions on his several fellows, and the rules may effectively forbid him to harm them in any manner and even require him to assist them in specific ways. In the Great Society many of the effects of a person's actions on various fellows must be unknown to him. It can, therefore, not be the specific effects in the particular case, but only rules which define kinds of actions prohibited or required, which must serve as guides to the individual.
We have usually no knowledge that any one factor will exert its effects independently of all others that can be varied, or that its effects are particularly simply related to variations in these other factors.
The Reader may here observe the Force of Numbers, which can be successfully applied, even to those things, which one would imagine are subject to no Rules. There are very few things which we know, which are not capable of being reduc'd to a Mathematical Reasoning, and when they cannot, it's a sign our Knowledge of them is very small and confus'd; and where a mathematical reasoning can be had, it's as great folly to make use of any other, as to grope for a thing in the dark when you have a Candle standing by you.
The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science.
I don't necessarily think there's a difference in terms of how the film industry and the ad industry view visual effects. If visual effects (or the lack thereof) are used as a tool to strengthen an idea, they're great. If they are meant to carry more of a load in the absence of a concept, they're a waste and a distraction.
I have begun to feel that there is a tendency in 20th Century science to forget that there will be a 21st Century science, and indeed a 30th Century science, from which vantage points our knowledge of the universe may appear quite different than it does to us. We suffer, perhaps, from temporal provincialism, a form of arrogance that has always irritated posterity.
I much prefer STEAM to STEM. The insertion of the A is arts writ large, and when you learn how to think, that means that you actually need to understand how others have thought before you, how have others made sense of the world.
The greatest challenge of the day is: how to bring about a revolution of the heart, a revolution which has to start with each one of us. When we begin to take the lowest places, to wash the feet of others, to love our brothers with that burning love, that passion which led to the cross, then we can truly say, 'Now I have begun'.
