In several different parts of the world, footprints from prehistoric human civilisations have been found preserved in either sand or volcanic ash. From these tracks it is possible to measure the foot length and the length of the stride. These measurements can be used to estimate both the height of the person who made the footprint and also whether the person was walking or running by using the following three formulas:

One of the advantages of identifying the general features of a calculation and then describing it mathematically is that the formula can then be used in either a computer or a calculator program to work out many different calculations quickly and efficiently. Many utility suppliers (gas, water, electricity, telephone) have tariffs based on a fixed daily (or monthly or quarterly) charge and a further charge based on how much you have used during the billing period.

For example in 2005, a

An ellipse with eccentricity e (where 0 < e < 1) is the set of points P in the plane whose distances from a fixed point F are e times their distances from a fixed line d. We obtain such an ellipse in standard form if

1. the focus F lies on the x-axis, and has coordinates (ae, 0), where a > 0;

2. the directrix d is the line with equation xÂ =Â a

3.1 Definition, properties and some applications

In the previous section we saw how to add two vectors and how to multiply a vector by a scalar, but we did not consider how to multiply two vectors. There are two different ways in which we can multiply two vectors, known as the dot product (or scalar product) and the vector product. They are given these names because the result of the first is a scalar and the result of the second is a vector. (We shall not consider vector products in this course.)

Discount can be calculated in the same way as an increase by a percentage. For example, Â£8 with 15% discount means you actually pay

7.4 Elixirs of the nervous system: neurotrophins

According to Section 7.2 axons obtain an elixir from targets at their synapses.

Confirmation that there is indeed an elixir came from a series of events that reveals how much of science really works. Elmer Bucker, working with Hamburger in the mid-1940s, had removed a limb bud from a chick and replaced it with a tumour from

Sensory material architectures: Concepts and methodologies for spatial tectonics and tactile respons
As the knowledge of material computation advances, continuing the seamless integration of design and fabrication, questions beyond materialization can be addressed with a focus on sensing, feedback, and engagement as critical factors of design exploration. This article will discuss a series of prototypes, design methodologies, and technologies that articulate a textile?s micro-architecture, at the scale of fibers and stitches, to instrumentalize simultaneous structural, spatial, and sensory-resp

Continuity and learning
This free course, Continuity and learning, has a practical and professional development focus. You will explore interactive dimensions of workplace learning: how people and workplace cultures create formal, informal, planned and unplanned opportunities to learn. You will read about 'biographical learning' research, where adults develop narratives to better understand key points of their learning lives. You will plan and carry out a brief, informal interview with a colleague, and your colleague w
