1970s: The Beginnings of Modern Formula One

Deaths were still a commonality, and there were many factors at play to blame. Many of the drivers felt that the danger level involved in the sport was unnecessarily high despite the changes in the rules that had been implemented by the end of the 1970s. The drivers crusade for improved safety was led in the 1970s by Jackie Stewart. After the needless and avoidable death of Ronnie Peterson at the Italian Grand Prix in 1978 the sport finally made the wholesale changes needed to bring it up towards the modern standards of safety the sport enjoys today. The 1970s was the last decade that Formula One raced at truly long circuits (i.e. with lap times close to or over 3 minutes); and going into the decade, Formula One still raced at the 5-mile Charade circuit, the 8.7 mile Spa-Francorchamps circuit and the 14.2 mile Nürburgring Nordschleife. Although all of the aforementioned circuits were improved with safety features, by 1977 Charade, Spa and the Nürburgring were all no longer on the calendar all for the same general reason- safety concerns. Safer circuits such as Paul Ricard, Zolder and Hockenheimring were built with safety features installed; and at the end of the decade Formula One had become a safer sport, but it was still dangerous. Ground effect, a technology that was able to create huge amounts of downforce with inverted aerofoils mounted on the sides of the car, was discovered and developed by Colin Chapman and his Lotus team in the mid 70s, and the technology was perfected with the dominant Type 79. All the other teams followed suit, and the performance of the cars skyrocketed over a period of 2 years.

After Niki Lauda's near-fatal accident at a nearly inaccessible point at the treacherous 14.2 mi (22.8 km) Nürburgring in West Germany, the circuit was taken off the 1977 calendar after being on the calendar for all but 4 seasons of Formula One up to 1976.
- 1977

Famous quotes containing the words beginnings, modern and/or formula:
“The frantic search of five-year-olds for friends can thus be seen to forecast the beginnings of a basic shift in the parent-child relationship, a shift which will occur gradually over many long years, and in which a child needs not only the support of child allies engaged in the same struggle but also the understanding of his parents.”
—Dorothy H. Cohen (20th century)
“Certainly for us of the modern world, with its conflicting claims, its entangled interests, distracted by so many sorrows, so many preoccupations, so bewildering an experience, the problem of unity with ourselves in blitheness and repose, is far harder than it was for the Greek within the simple terms of antique life. Yet, not less than ever, the intellect demands completeness, centrality.”
—Walter Pater (18391894)
“Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective positions of the beings which compose it, if moreover this intelligence were vast enough to submit these data to analysis, it would embrace in the same formula both the movements of the largest bodies in the universe and those of the lightest atom; to it nothing would be uncertain, and the future as the past would be present to its eyes.”
—Pierre Simon De Laplace (17491827)
