Making Matter Come Alive
Before life existed on Earth, there was just matter, inorganic dead
"stuff." How improbable is it that life arose? And -- could it use a
different type of chemistry? Using an elegant definition of life
(anything that can evolve), chemist Lee Cronin is exploring this
question by attempting to create a fully inorganic cell using a "Lego
kit" of inorganic molecules -- no carbon -- that can assemble, replicate
and compete.  (15:11)

Dear Zoo
A child wants a pet and decides to write to the zoo.  The zoo sends an elephant but he is too big so he is sent back. Next, a giraffe arrives but he is too tall so is sent back.  The story continues in this fashion with a fierce lion, a grumpy camel, a scary snake, a naughty monkey, and a jumpy frog arriving and being returned.  Finally a puppy arrives and is perfect.

People-centred designing
Designed products surround us all and range from bus tickets to buildings. This unit focuses firmly on usability and the increasingly important phenomenon of people-centred design. It aims to inform consumers of design (i.e., all of us) about this crucial characteristic of design. The unit is derived from the Open University course T211 on Design and Designing, but as well as stimulating interest in areas of concern for producers of design it might also provide an introduction to engineering, ma

4.1 The rate of evolution

I now want to move away from looking at the challenges facing all aquatic mammals, to examine very briefly what we know about the evolutionary history of the cetaceans. This group has travelled furthest from its terrestrial roots and made the fullest adaptation to life in the sea.

Since mammals evolved on land, it has long seemed reasonable to suggest that the origin of whales must have involved an evolutionary transition from the land to the water. But how can we explain the fact that

3.2 Natural dives

The physiology of the diving response can be studied in the laboratory, but investigating the behaviour of a diving mammal in its natural environment can be more of a problem. However, modern physiological techniques have made it possible to record continuously physiological variables (such as heart rate) and information on depth and position during the spontaneous dives in the wild that are part of the animal's normal behaviour. Most such findings show that the majority of an animal's dives

2.7 … and becoming more intelligent

Intelligence is a useful commodity: it can help an animal to make sense of its environment and cope with the demands of social behaviour (including courtship and competition). Hunters tend to be relatively intelligent, and otters, pinnipeds and cetaceans, for example, share a playful curiosity that is characteristic of animals that catch other animals for a living. Some especially extravagant claims have been made for the intelligence of the toothed whales, largely because these animals use c

2.5 … and getting larger

Size offers a number of biological advantages, including some protection from predation, but it can also help in reducing heat loss. A large mammal has a large body mass (generating heat) relative to its surface area (losing heat). But there will be constraints on any evolutionary trend of increasing body mass in some aquatic mammals. Seals, sea-lions and toothed whales have to remain agile enough to chase their prey, and the pinnipeds as a whole have to be able to move about on land, but the

2.1 Land versus water

Mammals share a number of biological characteristics that mark them out as members of the class Mammalia. Many of these are adaptations to a life on land. For example:

  • Mammals give birth to young at a relatively advanced stage of development and feed their young on milk.

  • Most mammals have hair, or fur, covering part or all of the body.

  • Mammals have a high metabolic rate and maintain a relatively high and constant body temp

7.4 Equilibrium positions and rates of reaction in this unit

Section 7 showed that if a reaction is to occur at a particular temperature, two conditions must be fulfilled: its equilibrium constant must be sufficiently large, and its rate sufficiently great. We finish by pointing out how this crucial distinction between the equilibrium constant and the rate reveals itself in Figure 52. The f

7.3 Is the rate of reaction very slow?

If the equilibrium position is very favourable, then the reason why Reaction 8.1 fails to occur at 525 °C must be that its rate is very slow. Usually, a reasonable response would be to increase the temperature yet further, but the structure and economy of the car gives us little scope to do this. The alternative is to use a catalyst, which leaves the equilibrium constant unchanged, while speeding the reaction up.

Let us look at the changes that take place in the internal energy

7.1 Introduction

So far, we have concentrated on the electronic and spatial structures of chemical substances, but we have not said much about chemical reactions. Now we turn to the question of why chemical reactions happen. To remind you of the basic ideas, we shall concentrate on one particular reaction which occurs in the modern motor car.
