Why use Openly Licensed Educational Resources?

Resources that are openly licensed benefit schools in a number of ways, but most notably they help to: Increase Equity – All students have access to high quality learning materials that have the most up-to-date and relevant content because openly licensed educational resources can be freely distributed to anyone. Save Money – Switching to educational materials that are openly licensed enables schools to repurpose funding spent on static textbooks for other pressing needs, such as invest...

 Knowing the World Requires Mathematics

For the things of this world cannot be made known without a knowledge of mathematics. For this is an assured fact in regard to celestial things, siDce two important sciences of mathematics treat of them, namely theoretical astrology and practical astrology. The first. . . gives us definite information as to the number of the heavens and of the stars, whose size can be comprehended by means of instruments, and the shapes of all and their magnitudes and distances from the earth, and thicknesses...

 1945 Warning of Bacterial Antibiotic Resistance

But I would like to sound one note of warning. Penicillin is to all intents and purposes non-poisonous so there is no need to worry about giving an overdose and poisoning the patient. There may be a danger, though, in underdosage. It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body. The time may come when penicillin can be bought by anyone in the...

 The Center of the Earth

Of all regions of the earth none invites speculation more than that which lies beneath our feet, and in none is speculation more dangerous; yet, apart from speculation, it is little that we can say regarding the constitution of the interior of the earth. We know, with sufficient accuracy for most purposes, its size and shape: we know that its mean density is about 5½ times that of water, that the density must increase towards the centre, and that the temperature must be high, but beyond thes...

 Science Must Have Practical Application in Ordinary Life

Though the parallel is not complete, it is safe to say that science will never touch them unaided by its practical applications. Its wonders may be catalogued for purposes of education, they may be illustrated by arresting experiments, by numbers and magnitudes which startle or fatigue the imagination but they will form no familiar portion of the intellectual furniture of ordinary men unless they be connected, however remotely, with the conduct of ordinary life.

 The Use of Gold for Money Leads to Efforts to Inflate Its...

Gold is abused and made into vessels of dishonour, and abolished from ideal society as though it were the cause instead of the instrument of human baseness; but, indeed, there is nothing bad in gold. Making gold into vessels of dishonour and banishing it from the State is punishing the hatchet for the murderer's crime. Money, did you but use it right, is a good thing in life, a necessary thing in civilised human life, as complicated, indeed, for its purposes, but as natural a growth as the bo...
