The location and the object for the 200 franc note are not hard to identify as representing CERN and the transformation of energy and matter in the LHC.
A measurement of the rate of change in high-energy neutrinos racing through Earth provides a record-breaking test of Einstein’s special theory of relativity.
Laughter punctuates the excited conversations, a mix of German and English. Drinks are passed around and children dart among the legs of the hundred or so scientists gathered together for one last time. The sky’s blue is deepening: only 90 minutes until sunset.
What is the universe made of? What are matter, energy, space, and time? How did we get here and where are we going? In particle physics, the classic place to look for answers is in giant accelerators where particles collide. But nature also provides a wealth of data.
On June 29, 2007, when Albrecht Wagner told an assembly of nearly 1800 people to go to lunch and return at 2 p.m. for a surprise, nobody could have expected what was coming.
As technology evolves, posters are getting easier to produce and pass around. But it still takes skill and imagination to illustrate the abstract ideas of physics.
Atomic element 94 was named “plutonium” after Pluto, the ninth planet from the Sun (now demoted to “minor planet” status.) By tradition, plutonium should have been assigned the symbol “Pl,” but co-discoverer Glenn Seaborg gave it the symbol “Pu” as
His photographs show scientists and experiments, large physics facilities and tiny devices, enthusiastic crowds of conference participants and lone researchers absorbed in thought.
