A Quote by James Lovelock

Composing computer programs to solve scientific problems is like writing poetry. You must choose every word with care and link it with the other words in perfect syntax. There is no place for verbosity or carelessness. To become fluent in a computer lnaguage demands almost the antithesis of modern loose thinking. It requires many interactive sessions, the hands-on use of the device. You do not learn a foreign language from a book, rather you have to live in the country for year to let the langauge become an automatic part of you, and the same is true for computer languages.
In view of all the deadly computer viruses that have been spreading lately, Weekend Update would like to remind you: when you link up to another computer, you're linking up to every computer that that computer has ever linked up to.
The attribution of intelligence to machines, crowds of fragments, or other nerd deities obscures more than it illuminates. When people are told that a computer is intelligent, they become prone to changing themselves in order to make the computer appear to work better, instead of demanding that the computer be changed to become more useful.
A computer is like a violin. You can imagine a novice trying ?rst a phonograph and then a violin. The latter, he says, sounds terrible. That is the argument we have heard from our humanists and most of our computer scientists. Computer programs are good, they say, for particular purposes, but they aren’t ?exible. Neither is a violin, or a typewriter, until you learn how to use it.
Until I reached my late teens, there was not enough money for luxuries - a holiday, a car, or a computer. I learned how to program a computer, in fact, by reading a book. I used to write down programs in a notebook and a few years later when we were able to buy a computer, I typed in my programs to see if they worked. They did. I was lucky.
First, we want to establish the idea that a computer language is not just a way of getting a computer to perform operations but rather that it is a novel formal medium for expressing ideas about methodology. Thus, programs must be written for people to read, and only incidentally for machines to execute.
Films are made the same today, as they've ever been made, in certain respects. The scriptwriting, the pre-production, the storyboarding, and the designing are all the same. The technique of animation has changed, in the sense that rather than drawing it by hand, we use a computer as a tool. The computer has become a pencil to draw or paint the images that we see in a film.
Similarly, computer literacy courses tend to produce computer people who know a lot about computers or a piece of software but they don't help people become fluent with the machine.
Before a kid learns how to use a computer that can solve mathematical problems, he or she should know how to do arithmetic without a computer.
Every time you turn on your new car, you're turning on 20 microprocessors. Every time you use an ATM, you're using a computer. Every time I use a settop box or game machine, I'm using a computer. The only computer you don't know how to work is your Microsoft computer, right?
With 'Scratch,' you create computer programs by snapping together graphical programming blocks, much like LEGO bricks, without any of the obscure syntax and punctuation of traditional programming languages. After creating an interactive 'Scratch' project, you can share it on the 'Scratch' website, just as you would share videos on YouTube.
Imagine you are writing an email. You are in front of the computer. You are operating the computer, clicking a mouse and typing on a keyboard, but the message will be sent to a human over the internet. So you are working before the computer, but with a human behind the computer.
I was really looking at computers as a way to understand the mind. But at M.I.T., my mind was blown by having a whole computer to yourself as long as you liked.I felt a surge of intellectual power through access to this computer, and I started thinking about what this could mean for kids and the way they learn. That's when we developed the computer programming language for kids, Logo.
A computer is a great device because it enables you to do anything which is automatic, anything that you don't need your understanding for. Understanding is outside a computer. It doesn't understand.
What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline. My answer to these questions is simple -it is the art of programming a computer. It is the art of designing efficient and elegant methods of getting a computer to solve problems, theoretical or practical, small or large, simple or complex. It is the art of translating this design into an effective and accurate computer program.
(in response to the question: what do you think of e-books and Amazon’s Kindle?) Those aren’t books. You can’t hold a computer in your hand like you can a book. A computer does not smell. There are two perfumes to a book. If a book is new, it smells great. If a book is old, it smells even better. It smells like ancient Egypt. A book has got to smell. You have to hold it in your hands and pray to it. You put it in your pocket and you walk with it. And it stays with you forever. But the computer doesn’t do that for you. I’m sorry.
I was the first to advocate the Web. But I am very troubled by this thing that every kid must have a laptop computer. The kids are totally in the computer age. There's a whole new brain operation that's being moulded by the computer.
