Feature for Today |
On 27 Nov 1826, John Walker (1781-1859), an English pharmacist from Stockton-on-Tees, invented the first practical, strike-anywhere, friction match, which he first sold on 7 Apr 1827, though he refused to patent his creation. He used three-inch splints of wood, tipped with potassium chlorate, antimony sulphide, and gum arabic. The match head was ignited by drawing it through a fold of fine glasspaper. An article on Matches in the Pharmaceutical Journal (1871) gives an informative history of matches. The use of phosphorus was abandoned as too dangerous. Doebereiner invented a lamp using zinc, sulphuric acid and platinum that produced a flame on demand, like a cigar lighter. As you can read, there was an interesting range of attempts in the history of matches to produce the reliable product as we now know it. |

Quotations for Today | |
| Mathematics education is much more complicated than you expected, even though you expected it to be more complicated than you expected. |
| There is no such thing as absolute truth and absolute falsehood. The scientific mind should never recognise the perfect truth or the perfect falsehood of any supposed theory or observation. It should carefully weigh the chances of truth and error and grade each in its proper position along the line joining absolute truth and absolute error. |
| The brain is waking and with it the mind is returning. It is as if the Milky Way entered upon some cosmic dance. Swiftly the head-mass becomes an enchanted loom where millions of flashing shuttles weave a dissolving pattern, always a meaningful pattern though never an abiding one. |

He developed the Giorgi International System of Measurement in 1901. Originally, he suggested that the basic units of scientific measurement be the metre, kilogram, second, and joule. In 1960, this system was subsequently endorsed by the General Conference of Weights and Measures, though the joule was replaced by another basic unit. What unit replaced the joule? |
