151. Discovery of radioactivity by Henri Becquerel 100 years ago - "Radioactivity" laboratory of PTR/PTB founded as early as 1912  
Date: 20.02.1996
Percental score: 6 %
On February 24, 1896, Henri Becquerel reported before the Académie des Sciences in Paris that a specific uranium-bearing crystal which had been brought to shine under the action of sunlight and had  
152. Building Acoustics en miniature  
Date: 14.05.2007
Percental score: 6 %
