Construction of a new $50, 000 building for the Ada S. McKinley Community house, 3201 South Wabash avenue, is scheduled for early summer, it was announced today by C.

To those who believe an engineering degree admits them to the circle of the elite, this may come as a shock. Evidently there are people who do not regard it as such.

The building, designed by Alderman & Martin, architects, will be of bull brick, steel and glass. Provisions will be made for addition of an adjoining anditorium- gymnasium to the side and a large play area in the rear. Offices of the stall", 11 reception hall, serving pantry, storage rooms and a large assembly room will occupy the ground floor. 011 the second floor will be a lounge, three activities rooms, an arts and crafts room, and another large assembly room. Both assem— bly rooms will have accordiomtype folding partitions by which each of the rooms can be divided into three classrooms. The McKinley house, formerly known as the Southside Settlement house, has served residents of the area for the past thirty-two years. Within the past five months at— tendance registration has more than tripled, and it now serves over 2,000 children and adults monthly in its programs of recreau tion, education and culture. Under Mrs. McKinley, who has been teacher, ofiice worker and di- rector since 1934, hundreds of chilu dren in need of supervision have hencfitted from the wholesome pro- gram of education and recreation. Her work has been instrumental in combating juvenile delinquency in an area which needs work of this type probably more than any other in the city. To an overcrowded area of tension and blight she brought the Negro’s first infant welfare station, the first American Le— gion organization, the first inter- racial program. A year ago the board of directors was reorganized to include seven representatives from Illinois Tech, which, with the Wieboldt founda- tion, has made a substantial con- tribution toward construction of the new building. Dean John F. White is secretary of the board, and William R. Hammond was ap~ pointed executive director in Octo— ber, 1949. Recently activities of the Good Neighboi society were merged with the McKinley house. to canard preach aura not A Chemistry Honors assembly will be presented next Tuesday at 1 p. m. in ISIMC. Alpha Chi Sigma and the American Institute of Chemical Engineers will present awards ranging from handbooks to medals to outstanding students in the chemistry, chemical engineer» ing and metallurgical engineering departments. Prizes are to be presented by the faculty advisers of the organi» zations sponsoring the awards: Dr. R. C. Kintner will present the Alpha Chi Sigma awards, and Dr. R. E. Peck will present the AlChE award. The guest speaker for the event will be Dr. Gustav Eglofl" of the Universal Oil Products company.

It’s true that to the uninitiated it may be a confusing thing, characterized by a myriad of numbers and oddly arranged gradations, but to the engineer it is. truly an auxiliary brain. The usefulness of the slipstick may make some forget about its origin but it enhances the appreciation that engineers feel towards the men who played a part in its evo- lution. A brilliant mathematician from Merchiston, Scotland, laid the groundwork which eventually gave rise to the slide rule. John Napier published his “Canon of Loga» rithms” in 1614.. He was touched by the tedious tasks confronting his fellow mathematicians. Presenting his system of loga- rithms to the world, Napier ran marked: “Seeing there is nothing that is so troublesome to mathe- matical practice, nor doth more molest and hinder calculators, than the multiplications, d i vi s i o n 5, square and cubical extractions of great numbers, which besides the tedious expense of time are for the most part subject to many slippery errors, I began therefore to con- sider in my mind by what certain and ready art I might remove these hindrances.” In 1620 a chap named Gunter put logarithmic divisions on a stick and by means of compasses made calculations on the stick. William Oughtred invented the first instru- ment that might be called a slide rule ten years later. He took two Gunter logarithmic scales, held them together by hand and ar— ranged them to slide along each other, reading the scales directly. lsaac Newton solved the cubic equation in 1675 by using three parallel logarithmic scales. He also suggested the use oi” the indicator. Those handy square and cube scales were added in 1722 by Warner. in 1755 Everard inverted the logarithmic scale and adapted the slide rule for gauging. The log-log scale was invented by a Frenchman named Roget in 1815. His countryman, Amadee Mannheim a lieutenant in the ar- tillery, devised the present form of slide rule bearing his name. The cylindrical slide rule was invented in 1881 by Edwin Thacher. The duplex slide rule sold by Keufl’el and Esscr was devised by William Cox in 1891. All engineering students are fan miliar with logarithms. To multi- ply two numbers together it is necessary only to take the log of each number, add, them together and find the antiulog' represented by the resulting total logarithm. If a scale is marked. on paper so that the distance from the begin— ning of the scale to any number on the scale is equal or propor- tional to the log of the number, one could, by adding: the distance of one number from the beginning of the scale to the distance of another number from the beginning of the scale (which would, in fact, be adding together the logs of the two numbers), read their product di- rcctly on the scale. In a, similar manner, division would solve the subtraction of logarithms. As a matter of fact, all calculations that can be per— formed through the medium of logarithms are made mechanically with the slide rule. The commonest form of slide rule is the ten-inch type that. most students carry. Cylindrical slide rules are available, but their greater accuracy is offset by their bullrinoss and corre- spondingly h i g h e it cost... The most novel and least useful slide rule on the market is one of the circular type built into the rim of a wrist watch. Slide rules having scales six inches in length, and shorter, are available and are usually accurate to only two places. Many students now own a new all~1netal-bodied slide rule which otters easily-read scales, improved arrangement and extra scales heretofore not. found on ten-inch rules. For example, it is possible to read reciprocals with the decimal point placed. With reasonable care the slide rule will give its user many years of service. One CE who graduated from Armour Institute in 1906 still uses the slide rule that he owned while attending: classed—e tine teen- timonial for the durability of both slide rules and Armour institute alumni. an i
