Science: Visualization Challenge 2008

science aaas The International Science & Engineering Visualization Challenge 2008
Some of science’s most powerful statements are not made in words. From the diagrams of DaVinci to Rosalind Franklin’s x-rays, visualization of research has a long and literally illustrious history. To illustrate is to enlighten.
How many people would have heard of fractal geometry or the double helix or solar flares if they had been described solely in words? In a world where science literacy is dismayingly rare, illustrations provide the most immediate and influential connection between scientists and other citizens, and the best hope for nurturing popular interest. Indeed, they are now a necessity for public understanding of research developments.
The National Science Foundation (NSF) and Science created the International Science and Engineering Visualization Challenge to celebrate that grand tradition—and to encourage its continued growth. The spirit of the competition is for communicating science, engineering and technology for education and journalistic purposes.

Immagini e comunicazione scientifica: dalla descrizione all’evocazione

pascolini Immagini e comunicazione scientifica: dalla descrizione all’evocazione (Alessandro Pascolini, INFN)
Abstract. Vengono esaminati alcuni aspetti del ruolo delle immagini nella scienza e
nella comunicazione scientifica. In particolare si discute il loro significato per la fisica contemporanea e si esaminano modelli storici di comunicazione al pubblico mediante immagini al fine di individuare strategie per programmi attuali.

Gilbert U-238 Atomic Energy Lab. A radioactive game?

Gilbert U-238 Atomic Energy Lab
The "Gilbert U-238 Atomic Energy Lab" was introduced by A.C. Gilbert in the spring of 1950 and sold for $42.50. Its components included:
1. three very low-level radioactive sources (alpha, beta and gamma particles)
2. four uranium-bearing ore samples
3. Geiger-Mueller radiation counter
4. Wilson Cloud Chamber to see paths of alpha particles.
5. Spinthariscope to see "live" radioactive disintegration.
6. Electroscope to measure radioactivity of different substances.
7. an "Atomic Energy Manual"
8. "Learn How Dagwood Splits the Atom" (comic book by Joe Musial, 1949)
