Algorithms are Subjective/Creative Things
he algorithm may be the essence of computer science – but it’s not precisely a scientific concept. An algorithm is a system, like plumbing or a military chain of command. It takes knowhow, calculation and creativity to make a system work properly. But some systems, like some armies, are much more reliable than others. A system is a human artefact, not a mathematical truism. The origins of the algorithm are unmistakably human, but human fallibility isn’t a quality that we associate with ...Folksonomies: programming computer science

Mathematics Should Also Inspire
So why do we learn mathematics? Essentially, for three reasons: calculation, application, and last, and unfortunately least in terms of the time we give it, inspiration. Mathematics is the science of patterns, and we study it to learn how to think logically, critically and creatively, but too much of the mathematics that we learn in school is not effectively motivated, and when our students ask, "Why are we learning this?" then they often hear that they'll need it in an upcoming math class o...Education in math focuses too much on the practicality of it and not the artistic appreciation.

Global Warming is a Land Management Issue
One of the main causes of warming is the increase of carbon dioxide in the atmosphere resulting from our burning of fossil fuels such as oil and coal and natural gas. To understand the movement of carbon through the atmosphere and biosphere, we need to measure a lot of numbers. I do not want to confuse you with a lot of numbers, so I will ask you to remember just one number. The number that I ask you to remember is one hundredth of an inch per year. Now I will explain what this number means. ...With proper land management, we can pull the excess carbon from the atmosphere and into biomass.

Science and Education Feed One Another
The progress of the sciences secures the progress of the art of instruction, which again accelerates in its turn that of the sciences; and this reciprocal influence, the action of which is incessantly increased, must be ranked in the number of the most prolific and powerful causes of the improvement of the human race. At present, a young man, upon finishing his studies and quitting our schools, may know more of the principles of mathematics than Newton acquired by profound study, or discovere...Progress in one secures progress in the other.

Bacon, Galileo, Descartes
The transition from the epoch we have been considering to that which follows, has been distinguished by three extraordinary personages, Bacon, Galileo, and Descartes. Bacon has revealed the true method of studying nature, by employing the three instruments with which she has furnished us for the discovery of her secrets, observation, experiment and calculation. He was desirous that the philosopher, placed in the midst of the universe, should, as a first and necessary step in his career, renou...Condorcet considers the last the most important of the era.

Direct Observation is Dead
The faith of scientists in the power and truth of mathematics is so implicit that their work has gradually become less and less observation, and more and more calculation. The promiscuous collection and tabulation of data have given way to a process of assigning possible meanings, merely supposed real entities, to mathematical terms, working out the logical results, and then staging certain crucial experiments to check the hypothesis against the actual empirical results. But the facts which a...Folksonomies: observation experimentation

The Problem with Sending Robots to Troubleshoot
Now if a robot is given an order, a precise order, he can follow it. If the order is not precise, he cannot correct his own mistake without further orders. Isn't that what you reported concerning the robot on the ship? How then can we send a robot to find a flaw in a mechanism when we cannot possibly give precise orders, since we know nothing about the flaw ourselves? 'Find out what's wrong' is not an order you can give to a robot; only to a man. The human brain, so far at least, is beyon...Folksonomies: troubleshooting softwaresupport
Folksonomies: troubleshooting softwaresupport
In 1955, in his story "Risk!" Isaac Asimov has Susan Calvin explain the problem with sending robots in to troubleshoot a situation. 57 years later, I find her words to acurately describe why it is hard to hand off certain support tasks to new developers.
