Modernist architecture: Roots (1920-1929)

...determined to win over a doubting public and architectural establishment, the Congres Internationaux d'Architecture Moderne (CIAM) had met for the first time. An immensely influential think-tank, CIAM sought to formalise the various roots of Modernism into a coherent set of rules. Its opening declaration called for architecture to be rationalised and standardised, and to...

How do you tell the biological sex of a T-Rex?

...determine the sex of a live T-Rex. But when all you have is fossils... how do you go about it?...[A stylised T-Rex] In living animals, it’s pretty easy to tell if one is a male or a female. You look at their, er, dangly bits, or lack of them, observe their mating behaviour, and also see how they give birth. In the fossil record, it is extremely rare to find examples of...

Electrochemical Grinding (ECG)

...determines the work gap, is typically 0.01–0.25 mm Although the wheels are more expensive than those for conventional grinding, overall wheel costs are only 1/10 as much, as only 2–5% of the wheel removed by abrasion. Low wheel wear means less frequent wheel dressing, although the longer runs, between dressing, necessitate more precise wheel truing than for...

...structure of the metal, due to attack by the etchant. Dimensions and tolerances depend on material, thickness and design of the photo-master, e.g. stainless steel (1 mm thick) ±0.2 mm and the aluminium alloy (1 mm thick) ±0.13 mm. Manufacturers should be consulted to determine specific dimensions and tolerances available for a given component. See Also: Laser Cutting...

...determined at the design stage. Whether it’s material choices, manufacturing processes or product durability, these decisions present exciting opportunities to develop products incorporating not only environmental, but also social and economic solutions. It is by addressing these three criteria; planet, people and profit, referred to as the ‘triple bottom line’,...

Does maths offer a better model for multi-candidate elections?

...determine the “strong” candidates. We define the “strong” candidates to be the smallest group of candidates with the property that everybody inside the group would beat everybody outside the group in two-person races. (This is also often called the Smith set, after the mathematician John H. Smith.) For instance, if there is a Condorcet candidate X, then X is the...

What is a scientific model?

...determining skylark numbers is none of the things I’ve measured? Maybe it’s something else. Maybe it’s weather or the slope of the field or the soil type, or something like this. Something I haven’t measured at all. So the model is essentially wrong because I haven’t measured the thing that’s the most important driver of skylark population numbers. It may...
