THE ORDER OF INVENTIONS The order in which inventions are made is very important, much more important than has ever been realised, because we tend automatically to think that later inventions are better than earlier ones.

DATA ENCRYPTATION In recent years, computer programmers have tried to make it easy for people to use computer systems. Unfortunately, in some situations the systems are too easy to use; they don’t have enough restrictions to safeguard secret information or to prevent an unauthorized person from using that information. Therefore, several methods have been devised to prevent computer crime.
THE MENACE OF THE MICRO Hardly a week goes by without some advance in technology that would have seemed incredible 50 years ago.

Power plants would produce 115 billion pounds of carbon dioxide a 5year running those appliances and they would eat 77 billion kilowatt-hours of electricity – if all were 1993 models.
ULTRASONICS Some of the world’s most interesting and useful sounds cannot be heard at all. Ultrasonics – the ‘too-high-to-hear sounds’ – can be used to drill, cut weld, clean, and inspect for cracks and flaws. Like all sounds, they travel in waves through the air or any other medium, but they have a far higher frequency than the sounds we hear.
