4. CERN and its changing accelerator landscape I experienced: – – PS/ISR, SPS, LEP, LHC – – And, of course, the construction periods in between 31/03/20144 1974 1978 1982 1986 1990 1994 1998 2002 2006 2010 2014 SPS: 76  UA1/UA2: 81  90 LEP (Aleph, Delphi, L3, Opal): 1989  2000 LHC: 2009 

5. Changing Nobel prize rules 1984: Awarded to experimentalist – – After discovery at CERN 2013: Awarded to theoreticians – – After discovery at CERN 31/03/20145 Rubbia/van der Meer 1978 1982 1986 1990 1994 1998 2002 2006 2010 2014 SPS: 76  UA1/UA2: 81  90 LEP (Aleph, Delphi, L3, Opal): 1989  2000 LHC: 2009  Englert/Higgs Charpak

7. Another Change: 25 years of Tim’s Web The Web (as of 1989) 31/03/20147 1978 1982 1986 1990 1994 1998 2002 2006 2010 2014 1974 My claim to fame: I refused an offer to become Tim’s manager! 1989: The Web was born BeforeAfter

8. Four Decades of Change inside a 50+ Year “Law” – – Moore, G.E.: Cramming more components onto integrated circuits. Electronics, 38(8), April 1965. 31/03/20148 1978 1982 1986 1990 1994 1998 2002 2006 2010 2014 1974 Moore’s Law 19652020? IBM PC CHEP’95

9. The Future ? Apparently, somebody (David Patterson?) said: – – The first fifty years of computing were interesting, but wait for the next fifty! One area that seems interesting (alongside BIG Computer Facilities): 31/03/20149 IoT (the Internet of Things)
